ISBN 5-89822-086-0 © Ставропольская государственная медицинская академия, 2007 Lesson № 1. Introduction to economics. Simply stated, economics is the study of how societies choose to allocate scarce resources among competing uses. Many of the decisions we make are economic decisions, and many of our interactions with others are influenced by economic institutions. To understand society, you must have a basic knowledge of economics. As you begin your study of economics, keep in mind that economics will teach you a new way of looking at the world. In some cases, you will find that the topics we discuss are completely unfamiliar to you. But most of the time you will be looking at things that you already know about from a different perspective. Probably the most important reason for studying economics is to learn a particular way of thinking. A good way to introduce economics is to review three of its most fundamental concepts - opportunity cost, marginalism, and efficient markets. If your study of economics is successful, you will find yourself using these concepts every day in making decisions, both on economic matters and on matters that have nothing to do with economics. Opportunity cost. What happens in an economy is the outcome of thousands of individual decisions. Households must decide how to divide up their incomes over all the goods and services available, in the marketplace. Individuals must decide whether to work or not to work, whether to go to school, and how much to save. Businesses must decide what to produce, how much to produce, how much to charge, and where to locate. It is not surprising that economic analysis focuses °n the process of decision making. Nearly all decisions involve trade-offs. There are advantages and disadvantages, costs and benefits, associated with every action and every choice. A key concept that recurs again and again in analyzing the decision-making process is the notion of opportunity cost. The full «cost» of making a specific choice includes what we give up by not making the alternative choice. That which we forgo, or give up, when we make a choice or a decision is called the opportunity cost of that decision. The concept applies to individuals, businesses, and entire societies. The opportunity cost of going to a movie is the value of the other things you could have done with the same money and time. If you decide to take time off in lieu of working, the opportunity cost of your leisure is the pay that you would have earned had you worked. Part of the cost of a college education is the income you could have earned by working full time instead of going to school. If a firm purchases a new piece of modem equipment for $3000, it does so because it expects that equipment to generate more profit. There is an opportunity cost, however, since that $3000 could have been deposited in an interest-earning account. To a society, 3 the opportunity cost of using resources for military hardware is the value of the private/civilian goods that could have been produced with the same resources. The reason that opportunity costs arise is that resources are scarce. Scarce simply means limited. Consider one of our most important resources - time. There are only 24 hours in a day, and we must live our lives under this constraint. Many things in life are scarce, and much of economics is concerned with behaviour in the face of scarcity. People are forced to make choices in the face of scarcity. If your neighbour mows his lawn today, he won't have time to take his children to the zoo, and this is an opportunity cost of mowing the lawn. Read the text and answer the questions. Text 1. THE SCOPE OF ECONOMICS. Most students taking economics for the first time are surprised by the bread of what they study. Some think that economics will teach them about the stock market or what to do with their money. Others think that economics deals exclusively with problems like inflation and unemployment. In fact, it deals with all these subjects, but they are pieces of a much larger puzzle. Economics has deep roots in, and close ties to, social philosophy. An issue of great importance to philosophers, for example, is distributional justice. Why are some people rich and others poor, and whatever the answer, is this fair? A number of nineteenth century social philosophers wrestled with these questions, and out of their musings economics as a separate discipline was born. The easiest way to get a feel for the breadth and depth of what you will be studying is to explore briefly the way economics is organized. First of all, there are two major divisions of economics: microeconomics and macroeconomics. Microeconomics deals with the functioning of individual industries and the behaviour of individual economic decision-making units: single business firms and households. Microeconomics explores the decisions that individual businesses and consumers make. The choices of firms about what to produce and how much to charge and the choices of households about what to buy and how much of it to buy help to explain why the economy produces the things it does. Another big question that microeconomics addresses is who gets the things that are produced. Wealthy households get more output than do poor households, and the forces that determine this distribution of output are the province of microeconomics. Why do we have poverty? Who is poor? Why do some jobs pay more than others? Why do teachers or plumbers or baseball pitchers get paid what they do? Think again about all the things you consume in a day, and then think back to that view out over a big city. Somebody decided to build those factories. Somebody decided to construct the roads, build the housing, produce the cars, knit the shirts, and smoke the bacon. Why? What is going on in all those buildings? It is easy to see that understanding individual micro decisions is very important to any understanding of your society. Macroeconomics, in its turn, deals with the functioning of national economic complex and the behaviour of the main classes and social groups. 4 Questions: 1. Do you like economics as a branch of science? If so, why? 2. How many years have you already studied economics? Have you got a feel for the breadth and depth of what you have studied? 3. Does economics have deep roots in, and close ties to, social philosophy? Why? 4. What problems does economics deal with? 5. Why, do you think, are some people poor and others rich? How can you explain this social phenomenon? 6. Which two main divisions of economics do you know? 7. What do microeconomics and macroeconomics deal with? 8. Which issue of economics is of great importance to philosophers and why? 9. Are there really a lot of people in our country, who lead a miserable existence? Give a short summery of the text. Text 2. WHY STUDY ECONOMICS? Some of you may already be excited by the prospect of studying economics, but others among you will answer the question posed in the heading with 'It was part of my course of study, so I had no choice.' To both the reluctant conscripts and the willing volunteers we offer hope and encouragement. Economics studies topics that are highly relevant both to decision-making in most jobs that you are likely to do in life and to understanding many of the most pressing issues facing today's world—free markets versus government intervention, resource exhaustion, pollution and environmental degradation, global warming, the revolution in digital communications media, government taxes and spending, employment and unemployment, inflation, the EU, the euro, changing living standards in advanced nations, growth and stagnation among many of the world's poorest nations. Thus, economics is both a preparation for taking day-today decisions in a firm or other organization, and training in the analysis of many of the 'big issues' of our time. One of the most important events in the first three quarters of the twentieth century was the rise of communism. One of the most important events in the last quarter of that century was communism's fall. By the first decade of the twentyfirst century, the century-long battle between free markets and government planning as alternatives for organizing economic activity had been settled in almost all countries with a degree of decisiveness that is rare for great social issues. Understanding why market-oriented, capitalist economies perform so much better than fully planned or highly government-controlled economies is a core issue in economics. Economic theories are expressly designed to help us understand the successes (and, where they occur, the failures) of free-market economies. 5 The triumph of market-oriented economies suggests that income- and wealth-creating activities are usually best accomplished through the efforts of private citizens operating in largely unregulated markets. But this is not the end of the story, for at least three fundamental reasons. First, although market economies certainly work better than fully planned economies, they do not work perfectly. One of today's great social issues is how best to allocate the responsibilities of government, leaving it to do what it can do best and leaving free markets to do what they can do best. We ask: 'What are the important roles that governments can play in improving the functioning of a basically market-oriented economy?' Second, market economies produce severe short-term cycles as well as longterm growth. Long-term growth has raised the living standards of the ordinary working person from the horrors and degradations in the early and mid-nineteenth century and described by Charles Dickens to those of the property-owning workers of today, whose living standards are higher than those of 99.9 per cent of all the people of all classes who ever lived on Earth. Yet capitalist growth is uneven growth because economic activity cycles around its rising trend. In recessions, unemployment is high and living standards typically stand still or even fall. Although each cycle tends to leave living standards higher than all previous cycles, the ups and downs of uneven market-driven growth can be upsetting to those affected by it. Third, capitalist growth is unequal growth. Although it is desirable to create national income and wealth, we also care about how these are distributed among all citizens. Poverty for a minority in the midst of plenty for the majority has always been a problem in wealthy countries—just as poverty for the majority has always been a problem for poor countries. We ask: 'What can governments do to alleviate the poverty and suffering of those who do not share in the income and employment that well-functioning market economies create for the majority?' The world is complex, and fully understanding its economic aspects requires much more economic theory than can be packed into one elementary textbook. But mastery of the subject to the level of this one book will contribute greatly to your understanding of many important issues and many of the policies directed at dealing with them. It will also provide you with a toolbox that will prove useful in the world of work, whatever occupation you eventually enter. *** A modern economy makes available millions of goods and services for people to choose from. It provides jobs for most people who want to work. It allows us to travel and communicate easily with anybody anywhere in the world. Yet no one has sat down and planned how all this will work. It has evolved as a response to economic forces interacting with individuals and institutions. One of our main tasks in this book is to understand how such an economy works, how well it works, and what can be done when it does not work well. If you want a pint of milk, you go to the shop and buy it. The shop owner is just one part of a complex supply chain that makes this milk available when you 6 want it. When the shop owner needs more milk, she orders it from the distributor, who in turn gets it from the bottling plant, which in its turn gets it from the dairy farmer. The dairy farmer buys cattle feed and electric milking machines, and gets power to run all his equipment by putting a plug into a wall socket where the electricity is supplied as he needs it. The milking machines are made from parts manufactured in several different countries throughout the world, while these parts in their turn are made from materials mined and refined in a dozen or more different countries. As it is with the milk you drink, so it is with everything else that you buy. When you go to the appropriate shop, what you want is normally in stock. Those who make these products find that all the required components and materials are available when needed — even though these things typically come from many different parts of the world and are made by people who have no direct dealings with each other. The economy is so good at delivering what we want when we want it that we only tend to notice when it goes wrong. Read the text and answer the questions. Text 3. HOW TO STUDY ECONOMICS? The study of economics should begin with a sense of wonder. Pause for? moment and consider a typical day in your life. For breakfast you might have bread made in a local bakery with flour produced in Minnesota from wheat grown in Kansas and bacon from pigs raised in Ohio, packaged in plastic made in New Jersey. You spill coffee from Colombia on your shirt made in Texas from textile shipped from South Carolina. After class you drive with a friend in a Japanese car on an interstate highway system that took 20 years and billions of dollars worth of resources to build. You stop for gasoline refined in Louisiana from Saudi Arabian crude oil brought to the United States on a supertanker that took three years to build at a shipyard in Maine. At night you call your brother in Mexico City. The call travels over newly laid fiber-optic cable to a powerful antenna that sends it to; transponder on one of over 1.000 communications satellites orbiting the earth. You use or consume tens of thousands of things, both tangible and intangible every day: buildings, the music of a rock band, the compact disc it is recorded on, telephone services, staples, paper, toothpaste, tweezers, soap, a digital watch, fire protection, antacid tablets, beer, banks, electricity, eggs, insurance, football fields, computers, buses, rugs, subways, health services, sidewalks, and so forth. One hundred twenty million people in the United States - almost half the total population -work at hundreds of thousands of different kinds of jobs producing nearly six trillion dollars worth of goods and services every year. Some cannot fine work, some choose not to work for pay. Some are rich, others are poor. The United States imports $60 billion worth of petroleum and petroleum products each year and exports $37 billion worth of food. High-rise office buildings go up in central cities. Condominiums and homes are built in the suburbs. In other places homes are abandoned and boarded up. Some countries are 7 wealthy. Others are impoverished. Some are growing. Some are stagnating. Some businesses are doing well. Others are going bankrupt. Economics is the study of how individuals and societies choose to use the scarce resources that nature and previous generations have provided. The key word in this definition is «choose». Economics is a behavioural science. In large measure it is the study of how people make choices. The choices that people make, when added up, translate into societal choices. Questions: 1. Are modern economies interacted now? How can you prove it? 2. What are the main features of modern world economies? 3. Is there a common international market today? 4. Does this market have influence on economic situation in Russia? 5. Why do students begin the study of economics with a sense of wonder? 6. Why, in your opinion, are some countries wealthy and others are impoverished? 7. Do you know how many people live in poverty in todays world? Is it possible to put an end to impoverishing people or not? What do you think of it? 8. Foreign scientists assure that economics is the study of how individuates and societies choose to use the resources provided them by nature and previous generations. Do you agree with such a point of view? 9. Are there specific economic laws that determine development of societies or people make their choices ignoring them? 10. Do you agree with the affirmation that economics is a behavioural science? How did the great economists of the past define economics? Exercises: 1. Complete the sentences by using the words from the texts: A) … deals with the functioning of national economic complex and the behaviour of the main classes and social groups. B) … explores the decisions that individual businesses and consumers make. C) By the first decade of the twenty-first century, the century-long battle between … and … as alternatives for organizing economic activity had been settled in almost all countries with a degree of decisiveness that is rare for great social issues. D) Economics is the study of how individuals and societies choose to use the … resources that nature and previous generations have provided. 2. List some of the choices you make on a daily basis in terms of how you spend your time and how you spend your money. 8 3. Make a list of all the different goods and services you typically buy in a normal week. In how many different markets does this suggest that a typical individual trades on a regular basis? 4. In what ways does money facilitate specialization and the division of labour? New vocabulary: economy; economics; microeconomics; macroeconomics; household; national economy; inflation; unemployment.

Give us some examples of positive statements. What does normative statement mean? Give us some examples of normative statements. What are the methods of Economics? Read the text and answer the questions: Text 1. METHODS OF ECONOMICS Economics asks and attempts to answer two kinds of questions, positive and normative. Positive economics attempts to understand behaviour and the operation of economic systems without making judgements about whether the outcomes are good or bad. It strives to describe what exists and how it works. What determines the wage rate for unskilled workers? What would happen if we abolished the corporate income tax? Who would benefit? Who would lose? The answers to such questions are the subject of positive economics. Normative economics, on the other hand, looks at the outcomes of economic behaviour and asks if they are good or bad and whether the outcomes can be made better. Normative economics involves judgements and prescriptions for preferred courses of action. Should the government be involved in regulating the price of gasoline? Should the income tax be changed to reduce or increase the burden on upper income families? Should AT&T have been broken up into a set of smaller companies? Should we protect the automobile industry from foreign competition? Should the savings and loan industry be regulated? Normative economics is often called policy economics. Questions: 1. What kind of questions does economics ask and attempt to answer? 2. What problems does positive and normative economics attempt to understand? 3. Does positive economics make judgements about behaviour and operation of economic systems and their outcomes? 4. Does normative economics involve judgements and prescriptions for preferred courses action of economics systems? 5. Should the income tax be raised or reduced in our country? What do you think of it? 6. Do you find that modern system of taxation in Russia is fair? 7. Why do people grumble at taxation today? Are modern taxes high now or don’t people like paying taxes at all? 8. Who collects taxes in Russia? How often do you fill in a tax declaration? 9. Do our modern industries need to be protected from foreign competition? 10. What are the outcomes of the national economy development within last 10 years? Read about methods of economics else and give a short summery of the texts. Text 2. ECONOMIC ADVICE: POSITIV AND NORMATIVE STATEMENTS Economists give advice on a wide variety of topics. If you read a newspaper, watch television news, or listen to commentaries on the radio you will often notice some economist's opinions being reported, perhaps on the prospects for unemployment, inflation, or interest rates, on some new tax, or on the case for privatization or regulation of an industry. Advice comes in two broad types: normative and positive. Normative statements depend on value judgements. They involve issues of personal opinion, which cannot be settled by recourse to facts. In contrast, positive statements do not involve value judgements. They are statements about what is, was, or will be: that is, statements that are about matters of fact. It is difficult to have a rational discussion of issues if positive and normative issues are confused. Much of the success of modern science depends on the ability of scientists to separate their views on what does, or might, happen in the world, from their views on what they would like to happen. For example, until the eighteenth century almost everyone believed that the Earth was only a few thousand years old. Evidence then began to accumulate that the Earth was thousands of millions of years old. This evidence was hard for most people to accept since it ran counter to a literal reading of many religious texts. Many did not want to believe the evidence. Nevertheless, scientists, many of whom were religious, continued their research because they refused to allow their feelings about what they wanted to believe to affect their search, as scientists, for the truth. Eventually all scientists came to accept that the Earth is about 4,000 million years old. Distinguishing what is true from what we would like to be, or what we feel ought to be, depends to a great extent on being able to distinguish between positive and normative statements. Text 3. MODELS. Economists often proceed by constructing what they call economic models. This term has several different but related meanings. Sometimes the term 'model' is used as a synonym for a theory, as when economists speak of the model of the determination of national income. Sometimes it may refer to a particular subset of theories, such as the Keynesian model or the neoclassical model of income determination. More often, a model means a specific quantitative formulation of a theory. In this case, specific numbers are attached to the mathematical relationships defined by the theory, the numbers often being derived from observations of the economy. 11 The specific form of the model can then be used to make precise predictions about, say, the behaviour of prices in the potato market, or the course of national income and total employment. Forecasting models used by the Bank of England and the International Monetary Fund (IMF) are of this type. The term 'model' is often used to refer to an application of a general theory in a specific context. So if we take our theory of consumer demand and apply it to the egg market in southern England, we might speak of a model of the southern English egg market. Finally, a model may be an illustrative abstraction, not meant to be elaborate enough to be tested. The circular flow in the scheme is a model of this sort: Illustrating how income flows between consumers and producers helps us to understand how the decisions of these two groups influence each other through labour markets and goods markets. However, the actual flows in any real economy are vastly more complex than the simple flows shown in the figure. Figure 2.1. The circular flow of income and expenditure The model helps us to understand what is going on without being detailed enough to yield specific testable predictions about real-world behaviour. In some ways, a model of this sort is like a political caricature. Its value is in the insights it provides that help us to understand key features of a complex world. Exercises: 1. Complete the sentences by using the words from the texts: A) Sometimes the term 'model' is used as a synonym for …, as when economists speak of the model of the determination of national income. B) Sometimes a model means a … of a theory. C) a model may be …, not meant to be elaborate enough to be tested. 2. Why does the distinction between positive and normative statements matter for economics? Which of the following statements are positive? A. Higher interest rates cause people to save more. B. People should save more. C. People are more worried about inflation than unemployment. D. Governments should do more to reduce carbon emissions in order to save the planet from global warming. E. High taxes on cigarettes discourage smoking. F. Smoking should be discouraged. 3. Which of the following statements are normative? 12 A. High income tax rates discourage effort. B. Road-use charges would increase traffic. C. Governments should tax the rich to help the poor. D. The tax system should be used to reduce traffic. E. Technical change is a bad thing because it puts some people out of work. F. The burning of fossil fuels is causing global warming. 4. Discuss the view why do economists use models in order to help explain how the economy works? New vocabulary: positive statement, normative statement, scientific method, economic model. Homework: 1.

Read the text “The famous Economists”. Adam Smith Adam Smith was a great scientist who made extraordinary contributions in economics. He was born in 1723 in Kirkcaldy, a small fishing town near Edinburgh, Scotland. His father was a customs officer. He died before his son was born. At the age of 28 Adam Smith became a Professor of Logics at the University of Glasgow. It was his first academic appointment. Some time later he became a tutor to a wealthy Scottish duke. Then he received a grant of £300 a year. It was a very big sum, 10 times the average income at that time. With the financial security of his grant, Smith devoted 10 years to writing his work which founded economic science. Its full title was An Inquiry into the Nature and Causes of the Wealth of Nations. It was published with great success in 1776. Adam Smith made economics a science. This Scottish economist is often regarded as the founder of political economy too. Adam Smith (1723-1790) developed the intuition that as long as firms are constrained by robust competition, their self-interested profit seeking inadvertently causes them to act in ways that are socially optimal — as though they are guided by an invisible hand to do the right thing. But Smith was not naive. He believed that businessmen prefer to collude rather than compete whenever possible, and that governments have a very important economic role to play in fostering the robust competition needed for the invisible hand to work its magic. He also believed that governments must provide many 15 essential public goods, like national defense, that aren't readily produced by the private sector. The Development of Economics: Adam Smith. Economics, like every other intellectual discipline, has its roots in early Greece and Rome; but economics was first considered as a branch of domestic science (home economics) dealing with such matters as the management of slaves and the allocation of manure among alternative agricultural uses. In the revival of learning that followed the Middle Ages, economics emerged as a branch of moral philosophy concerned with such issues as the ethics of loan interest and the «justness» of market-determined wages and prices. By the beginning of the eighteenth century, the subject had lost most of its theological overtones and had taken shape as an academic discipline, largely as a branch of political theory dealing with problems of government intervention in economic affairs. Then in 1776 the Scottish moral philosopher Adam Smith published the first edition of his monumental Inquiry into the Nature and Causes of the Wealth of Nations, and economics soon became an independent science. The Vision of Adam Smith Smith lived in an age when the right of rulers to impose arbitrary and oppressive restrictions on the political and economic liberties of their subjects was coming under strong attack throughout the civilized world. As other men of that time were arguing that democracy could and should replace autocracy in the sphere of politics, so Adam Smith argued that laissez-faire could and should replace government direction and regulation in economics. The «should» was so mixed with the «could» portion of Smith's analysis that much of his book seemed almost as much a political tract as a work of science. What gave the book lasting significance was the Smith's strong arguments that the economic activities of individuals would be more effectively coordinated through the indirect and impersonal action of natural forces of self-interest and competition than through the direct and frequently ill-conceived actions of government authorities. Smith opened minds to the existence of a «grand design» in economic affairs similar to that which Newton had earlier shown to exist in the realm of physical phenomena. The impact of Smith's ideas upon his contemporaries was widespread and immediate. As one modern scientist observed: «Before Adam Smith there had been much economic discussion; with him we reach the stage of discussing economics». That Smith's vision of the economy should ever have been considered original might seem strange to modern minds, but that would be because we now see economic phenomena in the light of his conception. As two leading scholars recently remarked, «The immediate «common sense» answer to the question, «What will an economy motivated by greed and controlled by a large number of different agents look like?» is probably: There will be chaos». That is certainly the answer that would have been given by most of Smith's contemporaries—before they read his book. The greatness of Smith's accomplishment lies precisely in the fact that he, unlike his predecessors, was able to think away extraneous 16 complications and so perceive an order in economic affairs that common sense did not reveal. It is one thing, of course, to say that Smith's conception of economic phenomena is original, another to suggest that it corresponds to contemporary experience. According to Smith, society in its economic aspect is a vast concourse of people held together by the desire of each to exchange goods and services with others. Each person is concerned directly only to further his own self-interest, but in pursuing that aim each «is led by an invisible hand» to promote the interests of others. Forbidden by law and social custom to acquire the property of other people by force, fraud, or stealth, each person attempts to maximize his own gains from trade by specializing in the production of goods and services for which he has a comparative advantage, trading part of his produce for the produce of others on the best terms he can obtain. As a consequence, the «natural forces» of market competition—the result of each person attempting to «buy cheap and sell dear»— come into play to establish equality between demand and supply for each commodity at rates of exchange (prices). The economic system (so Smith and later writers argued) is an essentially selfregulating mechanism that, like the human body, tends naturally toward a state of equilibrium (homeostasis) if left to itself. There are two types of commercial banks. A national bank is chartered by the federal government. About one third of all commercial banks are national. A state bank, which is smaller than a national bank, is chartered by an individual state. Alfred Marshall Alfred Marshall (1842-1924) invented the supply-and-demand method for analyzing markets. Applying mathematics to economic theory, he clearly differentiated between shifts of demand and supply curves and movements along demand and supply curves. In doing so, he cleared up 2,000 years of faulty reasoning. He also made the revolutionary prediction that the market price would be where the demand and supply curves cross. Marshall then went one step farther and realized that by comparing points along demand and supply curves with the market price, you could quantify the benefits that consumers and producers derive from market transactions. These benefits are, respectively, consumer surplus and producer surplus, and their sum is the total economic surplus. This method of quantifying the benefits of production and consumption is still used today and forms the basis of welfare economics, which studies the costs and benefits of economic activities. This method also just happens to illustrate in a very simple graph the intuition behind Adam Smith's invisible hand. The free market equilibrium, where demand and supply cross, is exactly the same as what a benevolent social planner would choose to do if she were trying to maximize social welfare by maximizing total economic surplus. In other words, a free market does indeed act "as if moved by an invisible hand" to promote the common good. 17 David Ricardo David Ricardo (1772-1823) discovered comparative advantage and argued correctly that international trade is a win-win situation for the countries involved. Comparative advantage destroyed the intellectual respectability of mercantilism, the mistaken theory behind colonialism that viewed trade as being one-sided and consequently argued that trade should be set up to benefit the mother country at the expense of its colony. In addition, Ricardo correctly analyzed the economic phenomenon of diminishing returns, which explains why costs tend to increase as you increase production levels. He was also a strong early proponent of the quantity theory of money, the idea that increasing the money supply will increase prices. John Maynard Keynes John Maynard Keynes, first Baron Keynes (1883—1946) is an English economist, whose The General Theory of Employment, Interest and Money (1936) proposed the prevention of financial crises and unemployment by adjusting demand through government control of credit and currency. He is responsible for that part of economics now known as macroeconomics. John Maynard Keynes saw the cause of a depression as reduced aggregate demand, and in the absence of any automatic stimulus to demand he argued that governments must intervene to increase aggregate demand and end depression. He suggested that governments stimulate consumption by putting money into consumers' pockets through tax cuts or directly increase governments' own expenditure to add to aggregate demand. John Maynard Keynes (1883-1946) invented modern macroeconomics and the idea of using government-provided economic stimuli to overcome recessions. Much of the rest of 20th-century macroeconomics was a series of responses to his seminal ideas. His most famous ideas were developed in response to the long agony of the Great Depression of the 1930s. He first asserted that the Great Depression was the result of a collapse in the expenditures being made on goods and services. He then asserted that monetary policy had been ineffective in combating the decline in expenditures. And he finally concluded, given his dismay about monetary policy, that fiscal policy was the only remaining source of salvation. In particular, Keynes believed that the best way to increase expenditures in such dire circumstances was for the government to spend heavily to pay for programs that would buy up lots of goods and services in order to get the economy moving again. Keynes's policy prescriptions were adopted during the Great Depression in many countries, including the United States. And while many of his specific ideas about the cause of the Great Depression and the best policies for dealing with 18 recessions are no longer embraced, his underlying idea that governments are responsible for taming the business cycle remains very much with us today. Karl Marx Karl Marx (1818-1883) was the foremost economist among 19th-century socialists. None of his major economic theories is now believed to be true, but because proponents of his Marxist ideas came to power in dozens of countries during the 20th century, he is surely one of the most influential economists who ever lived. (Marx gets the most space here not because he's the most important economist on this list, but because I have to take the time to explain his ideas before discrediting them. The ideas of the other economists on this list are already explained in detail in other places in this book.) Marx's most important intellectual contribution is his idea that capitalism is a historically unique form of social and productive organization. In Capital, he analyzed capitalism as a brand-new form of social and economic organization based on capital accumulation and factory production. He called the owners of the factories "capitalists" and argued that they would be forced to exploit the workers who labored in their factories. In particular, he believed that the only capitalists who would survive and whose businesses would grow were those who paid workers the minimum salaries necessary for the workers to survive. Thus, even as productivity and output rose rapidly, workers would endure permanent, grinding poverty out of which they could never rise except by means of a violent overthrow of the capitalists — an overthrow in which the workers would gain control over the factories. Marx argued that this violent overthrow would be facilitated by what he saw as an inevitable tendency toward concentration and monopoly. When there was only one monopoly firm in each industry, it would be much easier for the workers to revolt and take over the system. With a century and a quarter of hindsight, we know that Marx was wrong in his economic thinking. In particular, workers' wages do rise over time — in fact, they rise on average as fast as technological innovation increases productivity levels. That's because capitalists compete over the limited supply of workers, and wages get bid up as quickly as productivity improvements allow one capitalist to bid higher wages to steal workers away from other capitalists. In addition, competition does not lead to each industry being dominated by a single monopoly firm. Rather, competition remains robust in most industries and consequently delivers all the benefits of Adam Smith's invisible hand. Milton Friedman Milton Friedman (b. 1912) convinced economists that the quantity theory of money is, in fact, true: Sustained inflations are the result of sustained increases in 19 the money supply (printing too much money). This insight put limits on using monetary policy to stimulate the economy. Friedman also argued that the Great Depression was chiefly a monetary disaster and that its severity was the result of a gruesomely tight money supply that kept real interest rates much too high. This diagnosis of the cause of the Great Depression is now the standard explanation, meaning that the intellectual ammunition for Keynes's solution to recessions — large increases in government spending — has lost much of the sway that it once had. It has also led economists to conclude that monetary policy is more important than fiscal policy for regulating the economy and preventing recessions. Paul Samuelson Paul Samuelson (b. 1915) has made many contributions to economics. Perhaps the most important was crystallizing the idea that all economic behavior can be thought of as consumers and firms maximizing either utility or profits subject to a set of constraints. This idea of constrained maximization has become the dominant paradigm that governs how economists conceive of economic behavior. Samuelson also developed a judicious blending of Keynesian and classical ideas about the proper use of government intervention in the economy. Keynes argued for large government interventions to mitigate recessions. Classical economists like Smith and Ricardo argued for minimal government interventions, fearing that government interventions tend to make things worse. Samuelson's neoclassical synthesis states that during recessions the government should be willing to make large interventions in the economy to get it moving again, but when the economy is operating at full potential, the proper role of government is to provide public goods and take care of externalities. Many economists embrace this view of the government's place in the economy. Robert Solow Robert Solow (b. 1924) has made huge contributions to the understanding of economic growth and rising living standards. In addition to developing innovative models of how economies grow over time, he also showed that the dominant longrun force propelling economic growth is technological innovation. Before Solow, the economic profession believed that increases in output were the result of increases in inputs. In particular, increases in output were solely the result of either using more workers or more capital (such as bigger factories). What Solow demonstrated was that at most 50 percent of the long-run growth of living standards can be explained by increases in labor and capital. The rest has to be the result of technological innovation. This insight created a huge paradigm shift among economists that has resulted in the systematic study of technological innovation and the ways in which it can be 20 improved by government policies like patents and copyrights. It also opens up the refreshing possibility that technological innovation will allow us to enjoy higher living standards without having to constantly increase our use of the earth's resources.

Read the texts and answer the questions: Text 1. THE FACTORS OF PRODUCTION The private enterprise system, as do all economic systems, requires resources for its business to produce goods and services. The resources used to provide goods and services are the factors of production: land, labour, capital, and entrepreneurship. These four factors are blended together by a business to produce goods and services as shown in Figure. Let's examine each. Land is the natural resources that can be used to produce goods and services. Natural recources are all resources growing on and under the earth's surface, such as trees, minerals, oil, and gas. Labour is the total human resources required to turn raw materials into goods and services. It would include all employees of the business from top management through the entire organisation structure. Land Labour Capital Entrepreneurship Production Processes Finished Goods and Services Figure 4.1. Factors of production. Capital is the total of tools, equipment, machinery, and buildings used to produce goods and services. In this case capital does not refer simply to money. Money by itself is not productive: but when it purchases drills, typewriters, forklifts, and the building to place them in it becomes productive. Entrepreneurship is the group of skills and risk taking needed to combine the other three factors of production to produce goods and services. Entrepreneurship is the catalyst - like heat to a fire. It is supplied by an entrepreneur, an individual or individuals who are willing to take risks in return for profits. Text 2. ECONOMIC POLICY. EFFICIENCY Economic theory helps us understand how the world works, but the formulation of economic policy requires a second step. We must have objectives. 23 What do we want to change? Why? What is good and what is bad about the way the system is operating? Can we make it better? Such questions force us to be specific about the grounds for judging one outcome superior to another. What does it mean to be better? Four criteria are frequently applied in making these judgements: 1. Efficiency; 2. Equity; 3. Growth; 4. Market equilibrium. EFFICIENCY. In physics «efficiency» refers to the ratio of useful energy delivered by a system to the energy supplied to it. An efficient automobile engine, for example, is one that uses up a small amount of fuel per mile for a given level of power. In economics efficiency means allocative efficiency. An efficient economy is one that produces what people want and does so at the least possible cost. If the system allocates resources to the production of things that nobody wants, it is inefficient. When steel beams lie in the rain and rust because somebody fouled up a shipping schedule, this is inefficient. If a firm could produce its product using 25% less labor and energy without sacrificing quality, it is also inefficient. To use the term more technically, an efficient change in the allocation of resources is one that at least potentially makes some people better off without making others worse off. The clearest example of an efficient change is a voluntary exchange. If you and I each want something that the other has and we agree to exchange, we are both better off, and no one loses. If a company reorganizes its production or adopts a new technology that enables it to produce more of its product with fewer resources, without sacrificing quality, this is an efficient change; at least potentially, the resources saved could be used to produce more of something. Inefficiencies can arise in numerous ways. Sometimes they are caused by government regulations or tax laws that distort otherwise sound economic decisions. When only one firm exists in a market and competition is prohibited or nonexistent, the incentive for efficient allocation and innovation may be lost. If firms that cause environmental damage are in no way held accountable for their actions, the incentive to minimize those damages is lost, and the result is inefficient. We shall deal with the concept of efficiency in much more detail later. For now, though, it is important to understand two things about it. First, it assumes that the ultimate purpose of an economic system is to produce what people want. When we say a change makes people better off, it is the people themselves who define what «better off» means. For example, by engaging in a voluntary exchange, you and I reveal that we are both better off afterwards than before. A voluntary exchange is efficient because it improves the well-being of the participants as they themselves define it. Second, since most changes that can be made in an economy will leave some people better off and others worse off, we must have a way of comparing the gains and losses that may result from any given change. Most often we simply compare their sizes in dollar terms. A change is at least I potentially efficient if the value of the resulting gains exceeds the value of the J resulting losses. 24 Questions: 1. What does economics help us understand? 2.

What should we all do to increase the effeciency of national economic? Text 3. ECONOMIC POLICY. EQUITY While efficiency has a fairly precise definition that can be applied with some degree of rigour, equity («fairness») lies in the eye of the beholder. Few people agree on what is fair and what is unfair. To many fairness implies a more equal distribution of income and wealth. Fairness may imply alleviating poverty but the extent to which poverty should be reduced is the subject of enormous disagreement. For thousands of years philosophers have wrestled with the principles of justice that should guide social decisions. They will probably wrestle with such questions for thousands of years to come. Despite the impossibility of defining equity or fairness universally, public policy makers judge the fairness of economic outcomes all the time. Rent control laws were passed because some legislators thought that landlords treated low income tenants unfairly. Certainly most social welfare programs are created in the name of equity. Questions: 1. What is equity in your own opinion? How can you define this social category? 2. Do all people agree on what is fair and what is unfair? 3. Does fairness imply any poverty? To what extent? 4. What principles have philosophers wrestled with for thousands of years? Have they come to a common denominator? 5.

Are modern social welfare programs created in the name of equity or not? 8. Are students treated fairly or unfairly by the government? Text 4. ECONOMIC POLICY. GROWTH As the result of technological change, the building of machinery, and the acquisition of knowledge, societies learn to produce new things and to produce old things better. In the early days of the US economy it took nearly half the population to produce the required food supply. Today less than 2% of the country's population is engaged in agriculture. When we devise new and better ways of producing the things we use now and develop new products and services, the total amount of production in the economy increases. Economic growth is an increase in the total output of an economy. If output grows faster than the population, output per capita rises, and standards of living increase. Presumably, when an economy grows there is more of what people want. Rural and agrarian societies become modern industrial societies as a result of economic growth and rising per capita output. Some policies discourage economic growth and others encourage it. Tax laws, for example, can be designed to encourage the development and application of new production techniques. Research and development in some societies are subsidized by the government. Building roads, highways, bridges, and transport systems in developing countries may speed up the process of economic growth. If businesses and wealthy people invest their wealth outside their country rather, than in its own industries, growth in their home country may be slowed. Efficiency and growth of economic outcomes witness to stability of economic situation in this or that country. But stability itself is explicitly witnessed to by market situation taking into account that most national economics are market economies. Thus, market appears as the exterior and total criterion for judging economic. Questions: 1. Does acquisition of knowledge encourage to produce new things and to produce old things better? 2. Under what conditions does the total amount of production in the economy increase? 3. When does per capita output rise? 4.

Read the texts and answer the questions: Text 1.THE MAIN TYPES OF ECONOMIC SYSTEMS An economic system is the method society uses to allocate its resources (land, labour, capital, and entrepreneurship) to satisfy its needs. What distinguishes one economic system from another is the control of the factors of production and the interaction of business, government, and consumers. In the modern world there are three main types of economic systems: capitalism (or pure capitalism), mixed capitalism and communism (socialism). Capitalism (or pure capitalism, or a market economy), as it was originally described by Adam Smith in his eighteenth-century book «Wealth of Nations», is an economic system where the factors of production are in private hands and , economic decisions are made freely according to the market forces of supply and I demand. In this system the economic questions of What is to be produced? How much will be produced? Who will produce it? How much will it cost? Who will get it? are determined by the consumers in the marketplace. In pure capitalism consumers demand more of a product as its price decreases. This follows the common sense notion that people are willing to purchase something if it costs less. On the other hand: producers are more willing to supply a product that can be sold for a higher price. Being motivated by profit, they expect to earn more profit when they supply more. In pure capitalism the two factors of supply and demand will balance each other out in such a way that some middle ground called an equilibrium price will 29 be achieved. Producers will make as many units of a product as consumers are willing to purchase at the price producers must charge to make a reasonable profit. In pure capitalism industry and individuals use resources as they choose. The government takes a laissez-faire, or hands-off, approach and does not interfere in the economic system. Producers and consumers pursue their own self-interests. Producers make as much as they can sell and consumers buy as much as they can afford. In this system each person behaves in the best interests of society, as if guided by an invisible hand. The marketplace is regulated by the interaction of the buyers and producers. If a company produces a defective product or charges too much for the product it is rejected by consumers. As a result, the producer has to improve the quality of the product or reduce the price to make any sales. The marketplace, in essence the invisible hand, regulates economic conduct. Government does not have to do any regulating. Questions: 1. What is an economic system? 2. What distinguishes an economic system from another one? 3. What types of economic systems do you know? 4. In whose hands are the factors of production in capitalism? 5. Who makes economic decisions under capitalism? Does the marketplace have influence on them? 6. By what are producers motivated when they supply products to the market? 7. Whose interests do producers and consumers pursue in the market? 8. If a company produces a defective product or charges too much for the product, will it be sold or rejected by consumers? What do think of if? 9. Some economists affirm that the government does not interfere in the economic system. Are they right or wrong? Is it possible under capitalism? 10. Are you for or against the government's regulating of economic conduct in Russia? Text 2. MIXED ECONOMY Over time the United States has evolved to a system of mixed capitalism -an economic system based on a market economy with limited government involvement. The government has abandoned the principle of the invisible hand in favor of a more visible involvement in economic life. In mixed capitalism the government has two economic tools: the power to tax and the power to spend. By taxing individuals and businesses it acquires funds to provide essential public programs: defense, education, transportation, and social services. In turn the money spent for these services creates more demand for the goods and services produced by businesses. 30 In addition, the government has become involved in the economic system through: Government-owned entities such as the Tennessee Valley Authority, which provides power to rural communities; Government agencies that regulate the activities of some businesses, as when the Food and Drug Administration prevents a pharmaceutical company from selling a new medicine until tests are made; Government involvement in employer-employee relations, for example, setting a minimum wage and initiating programs to create jobs for the unemployed. Questions: 1. Which is the difference between pure and mixed capitalism? 2. What is mixed capitalism as an economic system based on? 3. In favour of what principle has the government of Russia abandoned the principle of the invisible hand? 4. Which economic tools does the government have in mixed capitalism? 5. How are the necessary funds acquired by the government to provide essential public programs? 6. Do the money spent for social services create more or less demand for the goods produced businesses? 7. May the Russian government interfere in the activities of private companies now or not? 8. Are you a partisan of free market or government regulating of economic conduct in our country or not?

COMMAND ECONOMY Another economic system is communism. This is an economic system under which the government controls the factors of production. Land, labour and capital are under the control of the government and entrepreneurship is supplied by the government. As a result, all the economic decisions about production, distribution, consumption, and property ownership are made by the government. It decides what will be produced, who will produce it, how many units will be made, how much it will cost and who will receive it. Supply and demand and competition have no influence in this system. Central government planners make all the economic decisions about production and resource allocation. Historical practice has shown that communism would not change capitalism automatically and directly. Its partisans assure of communism's coming through socialism which is considered as the first stage of communist society, or as an economic subsystem in which much ownership is private, but the government 31 controls the operation and direction of basic industries. This control and direction are based on the belief that there are certain products and services that everyone should have. In essence this means that these need to be controlled so that all people will have them - not just those people who have enough money. The industries normally are under control of the government include mining, steel production, transportation, communication, health care, and automanufacturing. In Sweden, for example, the government owns the transportation network, communications, the banks, and the mining, steel, and chemical industries. Questions: 1. What is communism?

MODERN ECONOMIC SYSTEMS When you examine the economic systems in the world today you will discover, that no examples of pure capitalism, or pure communism exist. Most economies are grouped in the center of a continuum that stretches from the complete private ownership and market economy of pure capitalism to the total public ownership of communism. Even in the Soviet Union some private enterprise existed. Private vendors, for example, could be seen in railroad stations and on country roads selling homegrown flowers and vegetables. Other economies that are called communist have even more traces of private ownership. Yugoslavia has developed an interesting variation of public ownership, with production decisions being made at the factory, rather than by the central government, and being regulated by supply and demand. 32 Questions: 1. Are there any examples of pure capitalism or pure communism in the world today? 2. Where are most of economic systems grouped now? 3. What kinds of ownership do you now? Which difference is between them? 4. Which ownership dominates under capitalism? And in socialism? 5.

TRADITIONAL SYSTEMS A traditional economic system is one in which behavior is based primarily on tradition, custom, and habit. Young men follow their fathers' occupations— typically, farming, hunting, fishing, and tool-making. Women do what their mothers did—typically, cooking, mending, and fieldwork. There are few changes in the pattern of production from year to year, other than those imposed by the vagaries of nature. The techniques of production also follow traditional patterns, except when the effects of an occasional new invention are felt. The concept of private property is often not well denned, and property is frequently held in common, such as common grazing land. Finally, production is allocated between the members of society according to long-established traditions. In short, the answers to the economic questions of what to produce, how to produce, and how to distribute are determined by what has happened in the past. Such a system works best in an unchanging environment. Under static conditions, a system that does not continually require people to make choices can prove effective in meeting economic and social needs. Traditional systems were common in earlier times. The feudal system under which most people lived in medieval Europe was a largely traditional society. Today only a few small, isolated, self-sufficient communities still retain mainly traditional systems; examples can be found in some of the most isolated parts of the Canadian Arctic, the Himalayas, the Amazon jungle, and isolated parts of Papua New Guinea. Text 6. GOVERNMENT IN THE MODERN MIXED ECONOMY Modern market economies in advanced industrial countries are based primarily on market transactions between people who voluntarily decide whether 33 or not to transact. Private individuals have the right to buy and sell what they wish, to accept or refuse work that is offered to them, and to move where they want when they want. But governments create the legal framework that governs transactions. Key institutions are private property and freedom of contract, both of which must be maintained by active government policies. The government creates laws of ownership and contract, and then provides the courts to enforce these laws. Governments are also responsible for provision of a stable-valued money which is the measuring rod for all prices. In modern mixed economies governments go well beyond these important basic functions. They intervene in market transactions to correct what are called 'market failures'. These are identifiable situations in which free markets do not work well. For example, natural resources such as fishing grounds and common pastureland tend to be overexploited to the point of destruction under free-market conditions. Some products, called public goods, are not provided at all by markets because, once produced, no one can be prevented from using them. So their use cannot be restricted to those who are willing to pay for them. Defence and law and order are public goods. In other cases private agents impose costs called externalities on others by their economic activities, such as when factories pollute the air and rivers—the public is harmed but has no part in the producers' decisions about what to make and how to make it. These are some of the reasons why free markets sometimes fail to function in desirable ways. They explain why citizens want governments to intervene and alter the outcome that would result if everything were left to the market. There are also some products, like health and education, that could be provided through the market, but which governments have decided should be provided by the state and (in some cases) free of charge. These are not pure public goods, but many countries' governments have decided that some level of minimum provision must be available to all, so this cannot be left to the market. These are sometimes referred to as merit goods. Also, there are important equity (or fairness) issues that arise from letting free markets determine people's incomes. Some people lose their jobs because firms are reorganizing in the face of new technologies. Others may keep their jobs, but the market values their services so poorly that they face economic hardship. The old and the chronically ill may suffer if their past circumstances did not enable them to save enough to support themselves. For many reasons of this sort, we accept government intervention to redistribute income by taking something from the 'haves' and giving it to the 'have-nots'. Almost everyone accepts that there should be some redistribution of incomes. Care must be taken, however, not to kill the goose that lays the golden egg. Taking too much from the 'haves' risks eliminating their incentive to work hard and produce income, some of which would be redistributed to the 'have-nots'. Governments also play a part in influencing the overall level of prices and in attempting to stabilize the economy against extreme fluctuations in income and employment. A stable price level and full employment are the two major goals of 34 what is called the government's macroeconomic policy. These are dealt with in the second half of this book. These are some of the reasons why all modern economies are mixed economies. Throughout most of the twentieth century, in advanced industrial societies the mix was altering towards more and more government participation in decisions about the allocation of resources and the distribution of income. In the last two decades of the century, however, there was a worldwide movement to lower the degree of government participation. Read the text and discuss about it. Text 7. MARKET AND FIRMS The term market structure refers to the type of market in which firms operate. Markets can be distinguished by the number of firms in the market and the type of product that they sell. The competitiveness of the market depends on the power of individual firms to influence market prices. The less power an individual firm has to influence the market in which it sells its product, the more competitive that market is. The extreme form of competitive structure occurs when each firm has zero market power. In such a case many firms sell an identical product and each must accept the price set by the forces of market demand and market supply. The firms can sell as much as they choose at the prevailing market price and have no power to influence that price. This extreme is called a perfectly competitive market structure. (Usually the term 'structure' is dropped and economists speak of a perfectly competitive market.) In it, there is no need for individual firms to compete actively with one another, since one firm's ability to sell its product does not depend on the behaviour of any other firm. For example, Essex and Somerset wheat farmers operate in a perfectly competitive market over which they have no power. The price of wheat is set in world markets, and there are thousands of suppliers to that market in many different countries. The perfectly competitive market structure—usually referred to simply as perfect competition—applies directly to a number of real-world markets. It also provides an important benchmark for comparison with other market structures. Our analysis of perfect competition is built on a number of key assumptions relating to the firm and to the industry. • Assumption 1. All the firms in the industry sell an identical or homogeneous product. • Assumption 2. Buyers of the product are well informed about the characteristics of the product being sold and the prices charged by each firm. • Assumption 3. The output of each firm, when it is producing at its minimum long-run average total cost, is a small fraction of the industry's total output. • Assumption 4. Each firm is a price-taker. This means that each firm can alter its output without significantly affecting the market price of its product. Each 35 firm must passively accept the existing market price, but it can sell as much as it wants at that price. • Assumption 5. There is freedom of entry and exit, which means that any new firm is free to enter the industry and start producing if it so wishes, and any existing firm is free to cease production and leave the industry. The difference between the wheat farmers that we considered earlier and Shell is in their degree of market power. Each firm that is producing wheat is an insignificant part of the whole market and so has no power to influence the price of wheat. The oil company, on the other hand, does have power to influence the price of petrol, because its own sales represent a significant part of the total sales of petrol, even though all the firms in the industry are selling a product that is close to homogeneous. A perfectly competitive market is one in which individual firms have zero market power. Monopoly is at the opposite extreme from perfect competition. A monopoly occurs when one firm, called a monopolist or a monopoly firm, produces an industry's entire output. In contrast to perfectly competitive firms, which are pricetakers, a monopolist sets the market price. Most real firms operate under intermediate market structures rather than the two extremes of perfect competition and monopoly. On the one hand, they are not monopolies because their industries contain several firms, which often compete actively against each other. Firms manufacturing cars, refrigerators, TV sets, breakfast cereals, and many other consumer goods are in industries containing several close rivals, usually both foreign and domestic. Even in small towns, residents find more than one chemist, garage, hairdresser, and supermarket competing for their patronage. On the other hand, these firms do not operate in perfectly competitive markets because the number of competing firms is often small and, even when the number is large, the firms are not price-takers. We may see firm behaviour in two intermediate market structures. One, which is called monopolistic competition, is close to perfect competition with one important difference: firms do not sell a homogeneous product. The second, called oligopoly, deals with industries that typically contain a few large firms that compete actively with each other. One easily tractable model of imperfect competition is monopolistic competition. Tractability of this model is achieved by limiting the form of interdependence between producers. We deal with this case first before discussing more general types of strategic interactions between firms in oligopolistic market structures. Monopolistic competition refers to a market in which there are many firms but each sells a differentiated product and so faces a downward sloping demand curve for its own product. The theory is based on four key assumptions. 1. Each firm produces one specific variety, or brand, of the industry's differentiated product. Each firm thus faces a demand curve that, although 36 negatively sloped, is highly elastic, because many close substitutes are sold by other firms. 2. The industry contains so many firms that each one ignores the possible reactions of its many competitors when it makes its own price and output decisions. Each firm makes decisions based on its own demand and cost conditions, and does not take any account of potential reactions by other firms. 3. There is freedom of entry and exit in the industry. If existing firms are earning profits, new firms have an incentive to enter. When they do, the demand for the industry's product must be shared among more brands. 4. There is symmetry. When a new firm enters the industry selling a new version of the differentiated product, it draws customers equally from all existing firms. For example, a new entrant that captured 5 per cent of the existing market would do so by capturing 5 per cent of the sales of each existing firm. Oligopoly is imperfect competition among the few; it applies to an industry that contains only a few competing firms. Each firm has enough market power to prevent it from being a price-taker, but at the same time each firm is subject to enough inter-firm rivalry to prevent it from considering the market demand curve as its own. In most modern economies this is the dominant market structure for the production of consumer and capital goods as well as many basic industrial materials such as steel and aluminium. Services, however, are often produced in industries containing a larger number of firms—although product differentiation prevents them from being perfectly competitive. Also, the absence of symmetry prevents them from being monopolistically competitive. Since some firms' products are closer substitutes for each other than other firms' products, firms do tend to take account of the behaviour of their closest competititors. In contrast to a monopoly, which has no competitors, and to a monopolistically competitive firm, which has many competitors, an oligopolistic firm faces a few competitors. Because there are only a few firms in an oligopolistic industry, each firm realizes that its competitors may respond to any move it makes. The prudent firm will take such possible responses into account. In other words, oligopolists are aware that all the decisions made by the various firms in the industry affect the other firms. This is the key difference between oligopolists on the one hand and perfect competitors, monopolistic competitors, and monopolies on the other. The behaviour of oligopolists is strategic, which means that they must take explicit account of the impact of their decisions on competing firms and of the reactions they expect from competing firms. In contrast, firms in perfect and monopolistic competition engage in non-strategic behaviour, which means they make decisions based on their own costs and their own demand curves without considering any possible reactions from their large number of competitors. The behaviour of a monopolist is also non-strategic: it has no competitors with whom to interact. In oligopolistic industries prices are typically administered. Products are usually differentiated. Firms engage in rivalrous behaviour, although the intensity of the rivalry varies greatly across industries and over time. Some aspects of this rivalrous behaviour can be analysed using the tools of economics, but it is also the 37 subject of strategy courses in business schools and the central topic running through thousands of business management books (a sample of which can be seen in any airport bookstore). Successful captains of industry, whose memoirs often sell millions of copies, are not those who are just good at deciding where marginal cost is equal to marginal revenue: rather, they are those who lead a large team of managers and workers in a complex competition to develop winning products and gain market share against teams of others trying to do the same.

MARKETS AND MONEY People who are specialized in doing only one thing, whether they are factory workers or computer programmers, must satisfy most of their needs by consuming goods and services produced by other people. In early societies exchange of products took place by simple mutual agreement between neighbours. In the course of time, however, trading became centred on particular gathering places called markets. For example, the French markets, or trade fairs, of Champagne were well known throughout Europe as early as the eleventh century. Even now, many towns have regular market days. For economists, however, the term 'market' has a much broader meaning. We use the term market economy to refer to a society in which people specialize in productive activities and meet most of their material wants through voluntarily agreed exchanges. Most employed people, for example, work for a single employer (at any one time) and buy goods and services in a wide range in outlets (such as shops and restaurants, or by phone, internet, etc.). Specialization must be accompanied by trade. People who produce only one thing must trade most of it to obtain all of the other things they require. Early trading was by means of barter, the trading of goods directly for other goods. But barter is costly in terms of time spent searching out satisfactory exchanges. If a farmer has wheat but wants a hammer, he must find someone who has a hammer and wants wheat. A successful barter transaction thus requires what is called a double coincidence of wants. Money eliminates the restrictive system of barter by separating the transactions involved in the exchange of products. If a farmer has wheat and wants 40 a hammer, she does not have to find someone who has a hammer and wants wheat: she merely has to find someone who wants wheat, and takes money in exchange. Then she finds a person who wishes to trade a hammer and gives up the money for the hammer. The existence of 'money' greatly expands the possibilities of specialization and trade. Questions: 1. What does barter mean? 2. When do economists use term market economy? 3. What is role of money in market economy? 3. How does money eliminate the restrictive system of barter? Text 2. WHAT IS MONEY? Money is denned as any generally accepted medium of exchange. A medium of exchange is anything that will be widely accepted in a society in exchange for goods and services. Although being a medium of exchange is usually regarded as money's defining function, money can also serve other roles: Money acts as a medium of exchange and can also serve as a store of value and a unit of account. A medium of exchange. if there were no money, goods would have to be exchanged by barter (one good being swapped directly for another). The major difficulty with barter is that each transaction requires a double coincidence of wants: I can only buy from someone who wants what I can offer in exchange. Anyone who specialized in producing one commodity would have to spend a great deal of time searching for suitable trading partners. Thus, a thirsty economics lecturer would have to find a brewer who wanted to learn economics before he could swap a lesson in economics for a pint of beer. The use of money as a medium of exchange alleviates this problem. People can sell their output for money and subsequently use the money to buy what they want from others. So a monetary economy typically involves exchanges of goods and services for money and exchanges of money for goods and services—but not exchanges of goods and services for other goods and services. The double coincidence of wants, which is required for barter, is unnecessary when a medium of exchange is used. By facilitating transactions, money makes possible the benefits of specialization and the division of labour, which in turn contribute to the efficiency of the economic system. It is not without justification that money has been called one of the great inventions contributing to human freedom and well-being. To serve as an efficient medium of exchange, money must have a number of characteristics. It must be readily acceptable and therefore of known value. It must 41 have a high value relative to its weight. (Otherwise it would be a nuisance to carry around.) It must be divisible, because money that comes only in large denominations is useless for transactions having only a small value. Finally, it must be difficult, if not impossible, to counterfeit. A store of value. Money is a convenient way to store purchasing power; goods may be sold today, and the money taken in exchange for them may be stored until it is needed. To be a satisfactory store of value, however, money must have a relatively stable value. A rise in the price level leads to a decrease in the purchasing power of money, because more money is required to buy a typical basket of goods. When the price level is stable, the purchasing power of a given sum of money is also stable; but when the price level is highly variable this is not so, and the usefulness of money as a store of value is undermined. Although in a non-inflationary environment money can serve as a satisfactory store of accumulated purchasing power for a single individual, even in those circumstances it cannot do so for society as a whole. A single individual can accumulate money and, when the time comes to spend it, can command the current output of some other individual. However, if all individuals in a society were to save their money and then retire simultaneously to live on their savings, there would be no current production to purchase and consume. Society's ability to satisfy wants depends on goods and services being available. If some of this wantsatisfying capacity is to be stored up for society as a whole, some goods that are produced today must be saved for future periods. In other words, money may be accumulated as savings to help individuals buy future goods, but it is the future real capital stock and labour resources that will determine future real output. Money and real wealth should not be confused. Money is a store of value for individuals but not for society as a whole. A unit of account Money also may be used purely for accounting purposes, without having a physical existence of its own. For instance, a government store in an imaginary centrally planned society might say that everyone had so many 'pounds' to spend or save each month. Goods could then be assigned prices and each consumer's purchases recorded, the consumer being allowed to buy until his or her allocated supply of pounds was exhausted. These pounds need have no existence other than as entries in the store's books, yet they would serve as a perfectly satisfactory unit of account. Whether they could also serve as a medium of exchange between individuals would depend on whether the shop would agree to transfer credits from one customer to another at the first customer's request. Banks will transfer pounds credited to current account deposits in this way, and so a bank deposit can serve as both a unit of account and a medium of exchange. Notice that the use of 'pounds' in this context suggests a further sense in which money is a unit of account. People think about values in terms of the monetary unit with which they are familiar. A related function of money is that it can be used as a standard of deferred payments. Payments that are to be made in the future, on account of debts and so 42 on, are reckoned in money. Money's ability to serve as a unit of account over time in this manner can be diminished if there is significant inflation. Questions: 1. When the double coincidence of wants, which is required for barter, is unnecessary? 2. Does money makes possible the benefits of specialization and the division of labour, which in turn contribute to the efficiency of the economic system? 3. When the purchasing power of a given sum of money is stable? 4. When the usefulness of money as a store of value is undermined? 5. Is money a store of value for individuals or for society as a whole? 6. May money used purely for accounting purposes? 7. How does money’s ability to serve as a unit of account over time alter if there is significant inflation? Give a short summery of the texts. Text 3. METALLIC MONEY All sorts of commodities have been used as money at one time or another, but gold and silver proved to have great advantages. They were precious because their supplies were relatively limited, and they were in constant demand by the wealthy for ornament and decoration. Thus, these metals tended to have a high and stable price. Further, they were easily recognized, they were divisible into extremely small units, and they did not easily wear out. Before the invention of coins, it was necessary to carry the metals in bulk. When a purchase was made, the requisite quantity of the metal was carefully weighed on a scale. The invention of coinage eliminated the need to weigh the metal at each transaction, but it created an important role for an authority, usually a monarch, who made the coins by mixing gold or silver with base metals to create convenient size and durability, and affixed his or her seal, guaranteeing the amount of precious metal that the coin contained. This was clearly a great convenience, as long as traders knew that they could accept the coin at its 'face value'. The face value was nothing more than a statement that a certain weight of gold or silver was contained therein. However, often coins could not be taken at their face value. A form of counterfeiting—clipping a thin slice off the edge of the coin and keeping the valuable metal— became common. This, of course, served to undermine the acceptability of coins, even if they were stamped. To get around this problem, the idea arose of minting the coins with a rough edge; then the absence of the rough edge would immediately indicate that the coin had been clipped. This practice, called milling, survives on some coins (such as the current UK 5p, lOp, Ј1, and Ј2 43 coins) as an interesting anachronism to remind us that there were days when the market value of the metal in the coin was equal to the face value of the coin. Not to be outdone by the cunning of their subjects, some rulers were quick to seize the chance of getting something for nothing. The power to mint coins placed rulers in a position to work a really profitable fraud. They often used some suitable occasion—a marriage, an anniversary, an alliance—to re-mint the coinage. Subjects would be ordered to bring their coins into the mint to be melted down and coined afresh with a new stamp. Between the melting down and the recoining, however, the rulers had only to toss some further inexpensive base metal in with the molten coins. This debasing of the coinage allowed the ruler to earn a handsome profit by minting more new coins than the number of old ones collected, and putting the extras in the royal vault. The result of debasement was inflation. The subjects had the same number of coins as before, and hence could demand the same quantity of goods. When rulers paid their bills, however, the recipients of the extra coins could be expected to spend them. This caused a net increase in demand, which in turn bid up prices. Debasing the coinage was a common cause of increases in prices. It was the experience of such inflations that led early economists to stress the link between the quantity of money and the price level. To this day, the revenue generated from the power to create currency is known as seigniorage. Today the possibility of debasement does not enter. The term applies to the revenue that accrues from the powers to print banknotes (which have very low production costs relative to their face value) and to require private banks to place non-interest-bearing deposits at the central bank. The benefits of seigniorage could arise simply because the monetary authorities print money and spend it, so its value would be equal to the increase in note issue each period. In practice, the relevant monetary authority is the central bank, which is a government-owned institution that is the sole money-issuing authority and acts as banker to the commercial banking system. The UK central bank is the Bank of England; for the United States it is the Federal Reserve Board, and for the euro area it is the European Central Bank (ECB). When the central bank provides bank notes to the private sector, it typically buys interest-bearing bonds with each new issue of notes. The seigniorage from the notes in circulation is thus equal to the interest per period on those bonds. So, for example, if the note issue was £100 and the central bank had bought £100 worth of bonds in issuing those notes, and the yield on the bonds was 5 per cent, then seigniorage would be £5 per year. Some seigniorage also arises from the policy of many central banks of forcing commercial banks to place non-interest-bearing deposits with them, which the central bank can also use to purchase interest-bearing securities. Text 4. PAPER MONEY The next important step in the history of money was the evolution of paper currency, one source of which was goldsmiths. Since goldsmiths had secure safes, 44 the public began to deposit their gold with them for safekeeping. Goldsmiths would give their depositors receipts promising to hand over the gold on demand. When any depositor wished to make a large purchase, she could go to her goldsmith, reclaim some of her gold, and hand it over to the seller of the goods. If the seller had no immediate need for the gold, he would carry it back to the goldsmith for safekeeping on his behalf. If people knew the goldsmith to be reliable, there was no need to go through the cumbersome and risky business of physically transferring the gold. The buyer needed only to transfer the goldsmith's receipt to the seller, who would accept it as long as he was confident that the goldsmith would pay over the gold whenever it was needed. If the seller wished to buy a good from a third party who also knew the goldsmith to be reliable, passing the goldsmith's receipt from the buyer to the seller here too could effect the transaction. The deposit receipt was 'as good as gold'. The convenience of using pieces of paper instead of gold is obvious. When it came into being in this way, paper money represented a promise to pay so much gold on demand. In this case the promise was made first by goldsmiths and later by banks. Such paper money, which became banknotes, was backed by precious metal and was convertible on demand into this metal. Text 5. FRACTIONALLY BACKED PAPER MONEY Early on, many goldsmiths and banks discovered that it was not necessary to keep a full ounce of gold in the vaults for every claim to an ounce circulating as paper money. At any one time, some of the bank's customers would be withdrawing gold but others would be depositing it, and most would be trading in the bank's paper notes without indicating any need or desire to convert them into gold. As a result, the bank was able to issue more money (initially notes, but later deposits) redeemable in gold than the amount of gold that it held in its vaults. This was good business, because the money could be invested profitably in interestearning loans (often called advances) to individuals and firms. The demand for loans arose, as it does today, because some customers wanted credit to help them over hard times or to buy equipment for their businesses. To this day, banks have many more claims outstanding against them than they actually have in reserves available to pay those claims. We say that the currency issued in such a situation is fractionally backed by the reserves. The major problem with a fractionally backed, convertible currency was maintaining its convertibility into the precious metal by which it was backed. The imprudent bank that issued too much paper money would find itself unable to redeem its currency in gold when the demand for gold was even slightly higher than usual. It would then have to suspend payments, and all holders of its notes would suddenly find that their notes were worthless. However, the prudent bank that kept a reasonable relationship between its note issue and its gold reserve would find that it could meet a normal range of demand for gold without any trouble. 45 If the public lost confidence and demanded redemption of its currency en masse, however, the banks would be unable to honour their pledges. The history of nineteenth-and early-twentieth-century banking around the world is full of examples of banks that were ruined by 'panics', or sudden runs on their gold reserves. When this happened, the banks' depositors and the holders of their notes would find themselves with worthless pieces of paper. Text 6. MODERN MONEY The total amount of money in the economy is called the money supply or the money stock. The creation of high-powered money is only part of the story of how the money supply is created, because most measures of the money supply include a wider range of assets than just the monetary base. In particular, money is usually defined to include bank deposits. Today's bank customers frequently deposit coins and paper money with the banks for safekeeping, just as in former times they deposited gold. Such a deposit is recorded as a credit to the customer's account. A customer who wishes to pay a debt may come to the bank, claim the money in currency, and then pay the money to someone else, who may himself redeposit the money in a bank. As with gold transfers, this is a tedious procedure. It is more convenient to have the bank transfer claims to money on deposit. As soon as cheques, which are written instructions to the bank to make a transfer, became widely accepted in payment for commodities and debts, bank deposits became a form of money called 'deposit money'. Deposit money is denned as money held by the public in the form of deposits in commercial banks that can be withdrawn on demand. Cheques, unlike banknotes, do not circulate freely from hand to hand; thus cheques themselves are not currency. However, a balance in a current account deposit is money; the cheque simply transfers that money from one person to another. Because cheques are easily drawn and deposited, and because they are relatively safe from theft, they have been widely used. New technology has recently replaced many cheque transactions by computer transfer. Plastic cards such as Visa, Mastercard, and Switch enable holders of bank accounts to transfer money to another person's account in new ways. The principle is the same, however: the balance in the bank account is the money that is to be transferred between customers, not the cheque or the plastic card. When commercial banks lost the right to issue notes of their own, the form of bank money changed, but the substance did not. Today banks have money in their vaults (or on deposit with the central bank) just as they always did. Once it was gold; today it is the legal tender of the times—fiat money. It is true today, just as in the past, that most of the banks' customers are content to pay their bills by passing among themselves the banks' promises to pay money on demand. Only a small proportion of the value of the transactions made by the banks' customers involves the use of cash. 46 Bank deposits are money. Today, just as in the past, banks can create money by issuing more promises to pay (deposits) than they have cash reserves available to pay out. The main reason that we are interested in the money stock is that if it grows too fast it will cause inflation. For this purpose, it is the broad measure of the money stock that includes bank deposits that is most relevant, as bank deposits can be used in payment for goods and it is often said that 'too much money chasing too few goods' is the source of inflation.

THE NATURE OF DEMAND The amount of a product that consumers wish to purchase is called the quantity demanded. Notice two important things about this concept. First, quantity demanded is a desired quantity. It is how much consumers wish to purchase, not necessarily how much they actually succeed in purchasing. We use phrases such as quantity actually purchased or quantity actually bought and sold to distinguish actual purchases from the quantity demanded. Second, note that quantity demanded is a flow. We are concerned not with a single isolated purchase, but with a continuous flow of purchases. We must, therefore, express demand as so much per period of time—for example 1 million oranges per day, or 7 million oranges per week, or 365 million oranges per year. The concept of demand as a flow appears to raise difficulties when we deal with the purchases of durable consumer goods (often called 'consumer durables'). It makes obvious sense to talk about a person consuming oranges at the rate of 30 per month, but what can we say of a consumer who buys a new television set every five years? This apparent difficulty disappears if we measure the demand for the services provided by the consumer durable. Thus, at the rate of a new set every five years, the television purchaser is using the service (viewing TV programmes) at the rate of 1/60 of a set per month. Five main variables are assumed to influence the quantity of each product that is demanded by each individual consumer: 1. The price of the product 2. The prices of other products 3. The consumer's income and wealth 4. The consumer's tastes 5. Various individual-specific or environmental factors List is conveniently summarized in what is called a demand function: Qdn=f(pn, p1…pn-1, I, H) 51 The term Qdn stands for the quantity that the consumer demands of some product, which we call 'product n'. The term pn, stands for the price of this product, while p1, … , pn-1 is a shorthand notation for the prices of all other products. The term I is the consumer's income. The term H stands for a host of factors that will vary from individual to individual, such as age, number of children, place of residence (e.g. big city, small town, country), and other assets. (Car owners, for example will demand petrol while non-car owners will demand train tickets.) There are also some environmental factors that will affect demand patterns, such as the state of the weather and the time of year. Although these factors matter in real markets, they are not central to our current analysis. Finally, the precise way in which the variables listed above affect demand is determined by the tastes of the consumer. The demand function is just a shorthand way of saying that quantity demanded, which is on the left-hand side, is assumed to depend on the variables that are listed on the right-hand side. The form of the function determines the nature of that dependence. (Recall that the 'form of the function' refers to the precise quantitative relation between the variables on the right-hand side of the equation and the variable on the left.) We will not be able to understand the separate influences of each of the above variables if we ask what happens when all of them change at once. To avoid this difficulty, we consider the influence of the variables one at a time. To do this, we use a device that is frequently employed in economic theory. We assume that all except one of the variables on the right-hand side of the above expression are held constant. Then we allow this one variable, say pn to change and see how the quantity demanded (Qdn) changes. We are then studying the effect of changes in one influence on quantity demanded, assuming that all other influences remain unchanged which means 'other things being equal' or 'holding others things constant'. Text 2. DEMAND AND PRICE We are interested in developing a theory of how products get priced. To do this, we hold all other influences constant and ask, 'How will the quantity of a product demanded vary as its own price varies?' A basic economic hypothesis is that the lower the price of a product, the larger the quantity that will be demanded, other things being equal. This negative relationship between the price of a product and quantity demanded is sometimes referred to as the law of demand. Why might this law be true? A major reason is that there is usually more than one product that will satisfy any given desire or need. Hunger may be satisfied by meat or vegetables; a desire for green vegetables may be satisfied by broccoli or spinach. The need to keep warm at night may be satisfied by several woollen blankets, or one electric blanket, or a bedsheet and an efficient central heating system. The desire for a holiday may be satisfied by a trip to the Scottish Highlands or to the Swiss Alps; the need to get there by an aeroplane, a bus, a car, or a train; and so on. Name any general desire 52 or need, and there will usually be several products that will contribute to its satisfaction. Now consider what happens if we hold income, tastes, population, and the prices of all other products constant and vary the price of only one product. First, suppose the price of the product rises. The product then becomes a more expensive way of satisfying a want. Some consumers will stop buying it altogether; others will buy smaller amounts; still others may continue to buy the same amount; but no rational consumer will buy more of it. Because many consumers will switch, wholly or partially, to other products to satisfy the same want, less will be bought of the product whose price has risen. For example, as meat becomes more expensive, consumers may switch some of their expenditure to meat substitutes; they may also forgo meat at some meals and eat less meat at others. Second, let the price of a product fall. This makes the product a cheaper method of satisfying any given want. Consumers will buy more of it and less of other similar products whose prices have not fallen. These other products have become expensive relative to the product in question. For example, when a bumper tomato harvest drives prices down, shoppers buy more tomatoes and fewer other salad ingredients, which have now become relatively more expensive than tomatoes. Text 3. THE DEMAND SCHEDULE AND THE DEMAND CURVE A demand schedule is one way of showing the relationship between quantity demanded and price. It is a numerical tabulation that shows the quantity that will be demanded at some selected prices. Table 7.1 shows one consumer's demand schedule for eggs. Mrs. Brown often eats boiled eggs for breakfast, and, living on her own, she often finds omelettes a convenient evening meal. But she does not have a lot of money, so she keeps an eye on the price of eggs when she does her weekly supermarket shopping. The table shows the quantity of eggs that she wishes to buy each month at six selected prices. For example, at a price of Ј1.50 per dozen, Mrs. Brown demands 3.5 dozen per month. For easy reference, each of the price-quantity combinations in the table is given a letter. Next we plot the data from Table 7.1 in Figure 7.1, with price on the vertical and quantity on the horizontal axis. The smooth curve drawn through these points is called the demand curve, even though it may often be drawn as a straight line. It shows the quantity that Mrs. Brown would like to buy at every possible price, and its negative slope indicates that the quantity demanded increases as the price falls. 53 Table 7.1. Mrs. Brown’s demand schedule for eggs Reference letter Price Quantity demanded (£ per dozen) (dozen per month) a 0,50 7,0 b 1,00 5,0 c 1,50 3,5 d 2,00 2,5 e 2,50 1,5 f 3,00 1,0 A single point on the demand curve indicates a single price-quantity relationship. The whole demand curve shows the complete relationship between quantity demanded and price. Economists often speak of the conditions of demand in a particular market as 'given' or as 'known'. When they do so they are referring not just to the particular quantity that is being demanded at the moment (i.e. not just to a particular point on the demand curve) but to the whole demand curve. The whole demand curve remains in one place so long as all variables other than the price of the product itself remain unchanged. Figure 7.1. Mrs. Brown’s demand curve So far we have discussed how the quantity of a product demanded by one consumer depends on the product's price, other things being equal. To explain market behaviour, we need to know the total demand of all consumers. To obtain a market demand schedule, we sum the quantities demanded by each consumer at a particular price to obtain the total quantity demanded at that price. We repeat the process for each price to obtain a schedule of total, or market, demand at all possible prices. A graph of this schedule is called the market demand curve. In practice, our knowledge of market demand is usually derived by observing total quantities of sales directly. The derivation of market demand curves by summing individual curves is a theoretical operation. We do it to understand the relation between curves for individual consumers and market curves. Text 4. SHIFTS IN THE DEMAND CURVE The demand schedule and the demand curve are constructed on the assumption of ceteris paribus (other things held constant). But what if other things change, as surely they must? What, for example, if consumers find themselves with more income? If they spend their extra income, they will buy additional quantities 54 of many products even though market prices are unchanged. But if consumers increase their purchases of any product whose price has not changed, the new purchases cannot be represented by the original demand curve. The rise in consumer income shifts the demand curve to the right, as shown in Figure 7.2. This shift illustrates the operation of an important general rule. A demand curve shifts to a new position in response to a change in any of the variables that were held constant when the original curve was drawn. Any change that increases the quantity of a product consumers wish to buy at each price will shift the demand curve to the right, and any change that decreases the quantity consumers wish to buy at each price will shift the demand curve to the left. Figure 7.2. Shifts in the demand curve We saw that demand curves have negative slopes because the lower a product's price, the cheaper it becomes relative to other products that can satisfy the same needs. Those other products are called substitutes. A product becomes cheaper relative to its substitutes if its own price falls. This also happens if the substitute's price rises. For example, eggs can become cheaper relative to pizzas either because the price of eggs falls or because the price of pizzas rises—either change will increase the amount of eggs that consumers are prepared to buy. For example, Mrs. Brown may eat more omelettes and fewer pizzas whenever she wants a quick meal. A rise in the price of a product's substitute shifts the demand curve for the product to the right. More will be purchased at each price. Products that tend to be used jointly with each other are called complements. Cars and petrol are complements; so are golf clubs and golf balls, bacon and eggs, electric cookers and electricity, or an aeroplane trip to Austria and tickets on the ski lifts at St Anton. Since complements tend to be consumed together, a fall in the price of either will increase the demand for both. For example, a fall in the price of cars that causes more people to become car owners will, ceteris paribus, increase the demand for petrol. A fall in the price of one product that is complementary to a second product will shift the second product's demand curve to the right. More will be purchased at each price. If consumers receive more income, they can be expected to purchase more of most products even though product prices remain the same. A product whose demand increases when income increases is called a normal good. A rise in consumers' incomes shifts the demand curve for normal products to the right, indicating that more will be demanded at each possible price. For a few products, called inferior goods, a rise in consumers' income leads them to reduce their purchases (because they can now afford to switch to a more expensive, but superior, substitute). 55 A rise in income will shift the demand for inferior goods to the left, indicating that less will be demanded at each price. If total income and all other determinants of demand are held constant while the distribution of income changes (i.e. some become richer and others become poorer), the demands for normal goods will rise for consumers gaining income and fall for consumers losing income. If both gainers and losers buy a good in similar proportions, these changes will tend to cancel out. This will not, however, always be the case. When the distribution of income changes, demand will rise for those goods favoured by those gaining income and fall for those goods favoured by those losing income. Changes in the characteristics of the individuals who make up the market will cause demand curves to shift. For example, a reduction in the typical number of children per family, as happened in the twentieth century, will reduce the demands for the things used by children or in childcare. If the number of retired people increases, there will be a rise in the demands for goods consumed during leisure times. Demand for some products is different at different times of year. Some of this is due to weather; for example, demand for electricity is higher in the winter when days are short and the weather is cold,3 and demand for cold lager and ice cream is higher in the summer during hot weather. Other variations may be due to traditions associated with annual festivals, such as buying presents at Christmas, or the timing of school holidays. From the point of view of our theory of demand these are exogenous forces—things that lie outside the theory, affecting demand, sometimes greatly, but not themselves being explained by the theory. If there is a change in tastes in favour of a product, more will be demanded at each price, causing the demand curve to shift to the right. In contrast, if there is a change in tastes away from a product, less will be demanded at each price, causing the entire demand curve to shift to the left. Notice that, since we are generalizing beyond our example of eggs, we have relabelled our axes 'price' and 'quantity', dropping the qualification 'of eggs'. The term quantity should be understood to mean quantity per period in whatever units the goods are measured. The term price should be understood to mean the price measured in pounds per unit of quantity for the same product. A movement down a demand curve is called an increase (or a rise) in the quantity demanded; a movement up the demand curve is called a decrease (or a fall) in the quantity demanded. Text 5. FIRMS’ MOTIVES Economic theory gives firms several attributes. First, each firm is assumed to make consistent decisions, as though it were run by a single individual decision-maker. This allows the firm to be treated as the agent on the production or supply side of product markets, just as the consumer is treated as the individual unit of behaviour on the consumption or demand side. 56 Second, firms hire workers and invest capital and entrepreneurial talent in order to produce goods and services that consumers wish to buy. (There are some markets in which firms sell to other firms, or the government, and in the labour market individuals sell their services to firms. But here we focus on consumer goods markets for simplicity.) Third, firms are assumed to make their decisions with a single goal in mind: to make as much profit as possible. This goal of profit maximization is analogous to the consumer's goal of utility maximization. The amount of a product that firms are able and willing to offer for sale is called the quantity supplied. Supply is a desired flow: it indicates how much firms are willing to sell per period of time, not how much they actually sell. Here we make a start on the analysis of supply, establishing only what is necessary for a theory of price. In later chapters we study the behaviour of individual firms, and then aggregate individual behaviour to obtain the behaviour of market supply. For present purposes, however, it is sufficient to go directly to market supply, the aggregate behaviour of all the firms in a particular market. Three major determinants of the quantity supplied in a particular market are: 1. The price of the product 2. The prices of inputs to production 3. The state of technology This list can be summarized in a supply function: Qsn=f (pn, F1, … Fm), where Qsn is the quantity supplied of product n; pn is the price of that product; F1, … Fm is shorthand for the prices of all inputs into production; and the state of technology determines the form of the function S. (Recall, once again, that the form of the function refers to the precise quantitative relation between the variables on the right-hand side of the equation and the one on the left.) Text 6. SUPPLY AND PRICE For a simple theory of price, we need to know how quantity supplied varies with a product's own price, all other things being held constant. We are only concerned Qsn=f (pn), that is, between the quantity that firms wish to supply and the price of the product itself. We will have much to say in later chapters about this relationship. For the moment, it is sufficient to state the hypothesis that, holding other things constant, the quantity of any product that firms will produce and offer for sale is positively related to the product's own price, rising when the price rises and falling when the price falls. All we need to note is that the basic reason behind this relationship is the way in which costs behave as output changes. Typically, the cost of increasing 57 output by another unit tends to be higher the higher is the existing rate of output. So, for example, if the firm is already producing 100 units per week, the cost of increasing output to 101 units per week might be Ј1, while if 200 units were already being produced, the cost of increasing output to 201 units might be Ј2. Clearly, the firm will not find it profitable to increase output if it cannot at least cover the additional costs that are incurred. As the price of the product rises, the firm can cover the rising costs of more and more additional units of output. As a result, higher and higher prices are needed to induce firms to make successive increases in output. The result is a positive association between market price and the firm's output. The supply schedule given in Table 7.2. It records the quantity that all producers wish to produce and sell at a number of alternative prices, rather than the quantity consumers wish to buy. Table 7.2. A market supply schedule for eggs Reference letter Price Quantity supplied (£ per dozen) ('000 dozen per month) u 0,50 5,0 v 1,00 46,0 w 1,50 77,5 x 2,00 100,0 y 2,50 115,0 z 3,00 122,5 The six points corresponding to the six price-quantity combinations shown in the table are plotted in Figure 7.3. The curve drawn through the six points is a supply curve for eggs. It shows the quantity produced and offered for sale at each price. The supply curve in Figure 7.3 has a positive slope. This is a graphical expression of the following assumption: The market price and the quantity supplied are positively related to each other. Figure 7.3. A supply curve for eggs Text 7. SHIFTS IN THE SUPPLY CURVE A shift in the supply curve means that, at each price, a different quantity is supplied. An increase in the quantity supplied at each price is plotted in Figure 7.4. 58 This change appears as a rightward shift in the supply curve. A decrease in the quantity supplied at each price causes a leftward shift. For supply-curve shifts there is an important general rule similar to the one stated earlier for demand curves: When there is a change in any of the variables (other than the product's own price) that affect the amount of a product that firms are willing to produce and sell, the whole supply curve for that product will shift. Figure 7.4. Shifts in the supply curve All things that a firm uses to produce its outputs—such as, in the case of an egg producer, chicken feed, labour, and egg-sorting machines— are called the firm's inputs. Other things being equal, the higher the price of any input used to make a product, the less will be the profit from making that product. Thus, the higher the price of any input used by a firm, the lower will be the amount that the firm will produce and offer for sale at any given price of the product. A rise in the price of any input shifts the supply curve to the left, indicating that less will be supplied at any given price; a fall in the price of inputs shifts the supply curve to the right. At any time, what is produced and how it is produced depend on the technologies in use. Over time, knowledge and production technologies change; so do the quantities of individual products that can be supplied. A technological change that decreases costs will increase the profits earned at any given price of the product. Since increased profitability leads to increased production, this change shifts the supply curve to the right, indicating an increased willingness to produce the product and offer it for sale at each possible price. As with demand, it is essential to distinguish between a movement along the supply curve (caused by a change in the product's own price) and a shift of the whole curve (caused by a change in something other than the product's own price). We adopt the same terminology as with demand: quantity supplied refers to a particular quantity actually supplied at a particular price of the product, and supply refers to the whole relationship between price and quantity supplied. Thus, when we speak of an increase or a decrease in supply, we are referring to shifts in the supply curve such as the ones illustrated in Figure 7.2. When we speak of a change in the quantity supplied, we mean a movement from one point on the supply curve to another point on the same curve. Text 8. PRICE ELASTICITY OF DEMAND In Figure 7.5 we were able to compare the responsiveness of quantity demanded along the two demand curves because they were drawn on the same 59 scale. You should not try to compare two curves without making sure that the scales are the same. Figure 7.5 The effect of the chape of demand curve Also, you must not leap to conclusions about the responsiveness of quantity demanded on the basis of the apparent steepness of a single curve. The hazards of so doing are illustrated in Figure 7.6. Both parts of the figure plot the same demand curve, but the choice of scale on the 'quantity' and 'price' axes serves to make one curve look steep and the other flat. In order to get a measure of responsiveness that is independent of the scale we use, so that it can be compared across products, we need to deal in percentage changes. A given percentage change in the amount of petrol purchased will be the same whether we measure it in gallons or litres. Similarly, although we cannot easily compare the absolute changes in kilos of carrots and barrels of oil, we can compare their two percentage changes. Figure 7.6 One demand curve draw on different scales Figure 7.7. Three constant-elasticity demand curves 60 These considerations lead us to the concept of the price elasticity of demand, which is defined as the percentage change in quantity demanded divided by the percentage change in price that brought it about. This elasticity is usually symbolized by the lower-case Greek letter eta, η: η = percentage change in quantity demanded percentage change in price The value of price elasticity of demand ranges from zero to minus infinity, in this section, however, we concentrate on absolute values, and so ask by how much the absolute value exceeds zero. Elasticity is zero if quantity demanded is unchanged when price changes, namely when quantity demanded does not respond to a price change. A demand curve of zero elasticity is shown as curve Dl in Figure 7.7 It is said to be perfectly or completely inelastic. As long as there is some positive response of quantity demanded to a change in price, the absolute value of elasticity will exceed zero. The greater the response, the larger the elasticity. Whenever this value is less than one, however, the percentage change in quantity is less than the percentage change in price and demand is said to be inelastic. When elasticity is equal to one, the two percentage changes are then equal to each other. This case, which is called unit elasticity, is the boundary between elastic and inelastic demands. A demand curve having unit elasticity over its whole range is shown as D3 in Figure 7.7. When the percentage change in quantity demanded exceeds the percentage change in price, the elasticity of demand is greater than one and demand is said to be elastic. When elasticity is infinitely large, there exists some small price reduction that will raise quantity demanded from zero to infinity. Above the critical price, consumers will buy nothing. At the critical price, they will buy all that they can obtain (an infinite amount, if it were available). The graph of a demand curve with infinite price elasticity is shown as D2 in Figure 7.7. Such a demand curve is said to be perfectly or completely elastic. Text 9. WHAT DETERMINES ELASICITY OF DEMAND? The main determinant of elasticity is the availability of substitutes. Some products, such as margarine, cabbage, Coca Cola, and the Peugeot 406, have quite close substitutes— butter, other green vegetables, Pepsi, and the VW Passat. When the price of any one of these products changes, the prices of the substitutes remaining constant, consumers will substitute one product for another. When the price falls, consumers buy more of the product and less of its substitutes. When the price rises, consumers buy less of the product and more of its substitutes. More broadly denned products, such as all foods, all clothing, tobacco, and petrol, have few if any satisfactory substitutes. A rise in their price can be expected to cause a smaller fall in quantity demanded than would be the case if close substitutes were available. 61 A product with close substitutes tends to have an elastic demand; one with no close substitutes tends to have an inelastic demand. There is no substitute for food: it is a necessity of life. Thus, for food taken as a whole demand is inelastic over a large price range. It does not follow, however, that any one food—say Weetabix or Heinz tomato soup—is a necessity in the same sense. Each of these has close substitutes, such as Kellogg's Cornflakes and Campbell's tomato soup. Individual food products can have quite elastic demands, and they frequently do. Durable goods provide a similar example. Durables as a whole have less elastic demands than do individual durable goods. For example, after a rise in the price of TV sets, some consumers may replace their personal computer or their hifi system instead of buying a new TV. Thus, although their purchases of television sets fall, their total purchases of durables fall by much less. Because many specific manufactured goods have close substitutes, they tend to have price-elastic demands. A particular Marks and Spencer own-brand raincoat could be expected to be price elastic, but all clothing taken together will be inelastic. This is because, while it is easy to substitute a Marks and Spencer raincoat with a John Lewis, or Self-ridge raincoat, you have to wear something in the winter and you cannot avoid wearing clothing altogether when its price in general rises relative to, say, the price of food. Any one of a group of related products will tend to have an elastic demand, even though the demand for the group as a whole may be inelastic. Text 10. INCOME ELASTICITY Economic growth has raised the real income of the average citizen of Europe and North America quite dramatically over the past two centuries. At low levels of income most money is spent on such basics as food, clothing, and shelter. As income rises an increasing proportion of expenditure tends to fall on manufactured goods, particularly such durables as cars, TV sets, and refrigerators. At yet higher levels of income more and more of any additional income goes to services such as foreign travel, entertainment, and education. The responsiveness of demand for a product to changes in income is termed income elasticity of demand, and is defined as percentage change in quantity demanded percentage change in income For most products, increases in income lead to increases in quantity demanded, and income elasticity is therefore positive. If the resulting percentage change in quantity demanded is larger than the percentage increase in income, ηy will exceed unity. The product's demand is then said to be income-elastic. If the percentage change in quantity demanded is smaller than the percentage change in income, ηy will be less than unity. The product's demand is then said to be incomeinelastic. In the boundary case, the percentage changes in income and quantity ηy = 62 demanded are equal, making ηy unity: the product is said to have a unit income elasticity of demand. If the product is a normal good, a rise in income causes more of it to be demanded, other things being equal, which means a rightward shift in the product's demand curve. If the product is an inferior good, a rise in income causes less of it to be demanded, which means a leftward shift in the product's demand curve. So normal goods have positive income elasticities while inferior goods have negative income elasticities. Finally, the boundary case between normal and inferior goods occurs when a rise in income leaves quantity demanded unchanged, so that income elasticity is zero. While virtually all observed price elasticities are negative, income elasticities are observed to be both positive and negative. The important terminology of income elasticity is summarized in Figure 7.8. These figure illustrates all possible reactions by showing a product whose income elasticity goes from zero to positive to negative. No specific good is likely to show a pattern exactly like this. Most goods will have a positive income elasticity at all levels of income—people demand more as they get richer. (It should be obvious that no good can have a negative income elasticity at all levels of income.) Figure 7.8. The relation between quantity demanded and income/ Text 11. CROSS-ALASTICITY The responsiveness of quantity demanded of one product to changes in the prices of other products is often of considerable interest. Producers of, say, beans and other meat substitutes find the demands for their products rising when cattle shortages force the price of beef up. Producers of large cars find their sales falling when the price of petrol rises dramatically after a large oil price rise. The responsiveness of demand for one product to changes in the price of another product is called cross-elasticity of demand. It is defined as percentage change in quantity demanded of product x ηxy = percentage change in price of product y Cross-elasticity can vary from minus infinity to plus infinity. Complementary goods have negative cross-elasticities, and substitute goods have positive cross-elasticities. Mobile phones and the calls that can be made on them, for example, are complements. A fall in the price of calls causes an increase in the demand for both 63 handsets and calls. Thus, changes in the price of calls and in the quantity of handsets demanded will have opposite signs—price of calls goes down and demand for handsets goes up. In contrast, mobile calls and fixed-line calls are substitutes: a fall in the price of mobile calls increases the quantity of mobile calls made but reduces the quantity demanded of fixed-line calls. Changes in the price of mobile calls and in the quantity of fixed-line calls demanded will, therefore, have the same sign. Text 12. SUPPLY ELASTICITY The price elasticity of supply is defined as the percentage change in quantity supplied divided by the percentage change in price that brought it about. Letting the lower-case Greek letter epsilon, ε, stand for this measure, its formula is percentage change in quantity supplied εs = percentage change in price Supply elasticity is a measure of the degree of responsiveness of quantity supplied to changes in the product's own price. Since supply curves normally have positive slopes, supply elasticity is normally positive. Figure 7.9 illustrates three cases of supply elasticity. The case of zero elasticity is one in which the quantity supplied does not change as price changes. Figure 7.9. Three constant-elasticity supply curves This would be the case, for example, if suppliers persisted in producing a given quantity and dumping it on the market for whatever it would bring. Infinite elasticity occurs at some price if nothing is supplied at lower prices but an indefinitely large amount will be supplied at that price. Any straight-line supply curve drawn through the origin, such as the one shown in part (iii) of the figure, has an elasticity of unity. The reason is that, for any positively sloped straight line, the ratio of p/q at any point on the line is equal to the ratio ∆p/∆q that defines the slope of the line. Thus, in the formula (∆q/∆p)(p/q) the two ratios cancel each other out. The case of unit supply elasticity illustrates that the warning given earlier for demand applies equally to supply. Do not confuse the geometric steepness of supply curves with elasticity. Since any straight-line supply curve that passes through the origin has an elasticity of unity, it follows that there is no simple correspondence between geometrical steepness and supply elasticity. The reason is that varying steepness (when the scales on both axes are unchanged) reflects varying absolute changes, while elasticity depends on percentage changes. 64 Text 13. WHAT DETERMINES ELASICITY OF SUPPLY? What determines the response of producers to a change in the price of the product that they supply? First, the size of the response depends in part on how easily producers can shift from producing other products to producing the one whose price has risen. If agricultural land and labour can be readily shifted from one crop to another, the supply of any one crop will be more elastic than if labour cannot easily be shifted. Here also, as with demand, length of time for response is critical. It may be difficult to change quantities supplied in response to a price increase in a matter of weeks or months, but easy to do so over a period of years. An obvious example concerns the planting cycle of crops. Also, new oilfields can be discovered, wells drilled, and pipelines built over a period of years, but not in a few months. Thus, the elasticity of supply of oil is much greater over five years than over one year, and greater over one year than over one month. Second, elasticity is strongly influenced by how costs respond to output changes. Exercises: 1.

The operation of the market clearly depends on the interaction between suppliers and demanders. At any moment, one of three conditions prevails in every market: (1) the quantity demanded exceeds the quantity supplied at the current price, a situation called excess demand; (2) the quantity supplied exceeds the quantity demanded at the current price, a situation called excess supply; or (3) the quantity supplied equals the quantity demanded at the current price, a situation called equilibrium. 71 Excess Demand Excess demand exists when quantity demanded is greater than quantity j supplied at the current price. Figure 9.1, which plots both a supply curve and a demand j-curve on the same graph, illustrates such a situation. As you can see, market I demand at $1.75 per bushel (50,000 bushels) exceeds the amount that farmers I are currently producing (25,000 bushels). When excess demand occurs in an unregulated market, there is a tendency for price to rise as demanders compete against each other for the limited supply. This tendency continues until the excess demand is eliminated. In Figure this occurs at $2.50, where quantity, demanded, has fallen from 50,000 to 35,000 bushels per year and quantity supplied has increased from 25,000 to 35,000 bushels per year. When quantity demanded and quantity supplied are equal and there is no further bidding, the process has achieved an equilibrium, a situation in which there is no natural tendency for further adjustment. Graphically, the point of equilibrium is the point at which the supply curve and the demand curve intersect. Such a process is called establishing proportional prices, and it is in foundation of different mechanisms of regulating them in the market. Figure 9.1. Excess demand. Excess Supply Excess supply exists when the quantity supplied exceeds the quantity demanded at the current price. As with excess demand, the mechanics of price adjustment in the face of excess supply can differ from market to market. When there is a surplus of a particular product, that product remains unsold. If automobile dealers find themselves with unsold cars in the fall when the new models are coming in, for example, you can expect to see price cuts. Sometimes dealers offer discounts to encourage buyers; sometimes buyers themselves simply offer less than the price initially asked. In any event, when quantities supplied exceed quatities demanded at the current prices, stores cut prices. Questions: 1. What does the operation of the market depend on? 2.

Macroeconomics is the study of how the economy behaves in broad outline without dwelling on much of its interesting, but sometimes confusing, detail. Macroeconomics is concerned largely with the behaviour of economic aggregates, such as total national product, total investment, and exports for the entire economy. It is also concerned with the average price of all goods and services, rather than the prices of specific products. These aggregates result from activities in many different markets and from the behaviour of different decision-makers such as consumers, governments, and firms. In contrast, microeconomics deals with the behaviour of individual markets, such as those for wheat, computer chips, or strawberries, and with the detailed behaviour of individual agents, e.g. firms and consumers. In macroeconomics we add together the value of cornflakes, beer, cars, strawberries, haircuts, and restaurant meals along with the value of all other goods and services produced, and we study the aggregate national product. We also average the prices of all goods and services consumed and discuss the general price level for the entire economy— usually just called the price level. In practice, the averages of several different sets of prices are used. For example, one important index measures the average price of the goods and services bought by the typical consumer. In Britain it is known as the retail price index (RPI), while the equivalent in some other countries (and the measure used for the official inflation target in the UK) is called the consumer price index (CPI). We know full well that an economy that produces much wheat and few cars differs from one that produces many cars but little wheat. We also know that an economy with cheap wheat and expensive cars differs from one with cheap cars and expensive wheat. Studying aggregates and averages often means missing such important differences, but in return for losing valuable detail we are able to view the big picture. In macroeconomics we look at the broad range of opportunities and difficulties facing the economy as a whole. When national product rises, the output 73 of most firms, and the incomes of most people, usually rise with it. When interest rates rise, most borrowers, including firms and homeowners, have to make bigger payments on their debts, though many savers will get a higher return on their savings. When the price level rises, virtually everyone in the economy is forced to make adjustments, because of the lower value of money. When the unemployment rate rises, workers are put at an increased risk of losing their jobs and suffering losses in their incomes. These movements in economic aggregates are strongly associated with the economic well-being of most individuals: the health of the sectors in which they work and the prices of the goods that they purchase. These associations between the health of the macroeconomy and the economic fortunes of many people are why macroeconomic aggregates (particularly inflation, unemployment, productivity, interest rates, and the balance of payments) are often in the news. We also study how governments can use monetary and fiscal policy to stimulate economic activity when they are worried about recessions, and to dampen it down when they are worried about inflationary pressures caused by booms. Text 3. MAJOR MACROECONOMIC ISSUES We need a separate subject called macroeconomics because there are forces affecting the economy as a whole that cannot be fully or simply understood by analysing individual markets and individual products. A problem that is affecting all firms, or many workers, in different industries may need to be tackled at the level of the whole economy. Certainly, if circumstances are common across many sectors of the economy, then analysis at the level of the whole economy may help us to understand what is happening. Let us look at some of the issues that are best thought about in a macroeconomic context. Economic growth Both total and per capita output have risen for many decades in most industrial countries. These long-term trends have produced rising average living standards. Long-term growth is the predominant determinant of living standards and the material constraints facing a society from decade to decade and generation to generation. Macroeconomics has traditionally taken the trend in output as given and looked at how to minimize deviations from that trend. Growth is therefore a clear objective of macro-economic policy. Business cycles The economy tends to move in a series of ups and downs, called business cycles, rather than in a steady pattern. During recessions many businesses go bust, while profits fall for the survivors. In contrast, during a boom demand for most products rise, profits rise, and most businesses find it easy to expand. Understanding the business cycle is therefore important for successful businesses. Expanding capacity during the onset of a recession could be a recipe for disaster, while having too little capacity during a boom may result in a lost opportunity. Most importantly, although business cycles are beyond the control of individual 74 firms, firms do need to understand that the economy moves in cycles. Governments sometimes claim that their policies will bring stable growth and the end to cycles, but business cycles have been around for a long time, and they are likely to be with us for much longer yet. Macroeconomics as a subject was invented to help produce policies that could ameliorate economic fluctuations. Much of what follows is devoted to explanations of I why the economy goes through these ups and downs, and what, if anything, the government can do about them. Productivity Economic growth can be achieved either by using more inputs, such as increased capital or numbers of workers, or by getting more output for any given amount of inputs. The latter is known as productivity growth. Increasing productivity is a central target of most governments, as this is the most obvious way to make real incomes grow. Labour productivity (calculated as either output per worker or output per hour worked) is especially important in this regard, as growth in this is a necessary condition for sustained growth of real wages. Those who do not work do not produce, so the real living standards of the entire population are ultimately determined by the output per head of each of those who are in work. Labour productivity can increase if workers have more capital to work with, but over the long term what matters is technical progress. Inflation Swings in economic activity have usually accompanied swings in inflation. Generally, attempts by governments to control high inflation have tended to bring about recessions. However, the relationship between inflation and recession has changed over time. An important policy problem for governments in the past has been to stimulate economic activity without causing inflation. The rise in inflation during boom times has often led policy-makers to raise interest rates or taxes in order to bring inflation under control. When inflation falls after a recession, policymakers have often felt that they have the leeway to stimulate the economy again. But they have to tread carefully to achieve a suitable balance between stimulus and contraction, and we will learn below that timing policy interventions in order to achieve a desired outcome is not a simple matter. More recently policy-makers have become much more cautious in their attempts to influence the cycle in the economy. Unemployment A recession in economic activity causes an increase in unemployment. A new bout of high unemployment can never be ruled out, even for those countries where it has been low for some time; and even in countries where aggregate unemployment is not a major problem there are still big problems of youth unemployment or unemployment among certain ethnic groups, which are of great social and political concern. The main method of reducing aggregate unemployment that economists developed early in the twentieth century was for governments to increase their spending and reduce taxes. Such deliberate use of government spending and taxes to influence the economy is known as fiscal policy. 75 Government budget deficits At one time it was thought that budget deficits might be good for the economy because government spending created jobs. Nowadays there is more concern about the potential burden of the debt, in the form of interest, which has to be paid by taxpayers and which, therefore, keeps taxes high. Interest rates In addition to fiscal policy, government (or the monetary authority where this is independent of government) has available the tools of monetary policy. Monetary policy involves changing interest rates in order to influence the economy. High interest rates are a symptom of a tight monetary policy. When interest rates are high, firms find it more costly to borrow, and this makes them more reluctant to invest. Individuals with mortgages or bank loans are also hit by high interest rates, since it costs them more to make their loan repayments. Hence high interest rates tend to reduce demand in the economy—firms invest less, and those with mortgages have less to spend. Low interest rates tend to stimulate demand. Another important channel of monetary policy is via the exchange rate, at least for countries whose exchange rates are flexible. Exchange rate changes can affect the relative prices, and thereby the competitiveness, of domestic and foreign producers. A significant rise in the cost of buying domestic currency on the foreign exchange market makes domestic goods expensive relative to foreign goods. This may lead to a shift of demand away from domestic goods towards foreign goods. Such shifts have an important influence on domestic economic activity. Targets and instruments The issues that we have just discussed are of two types. First, there are issues that really matter for their own sake, things that affect living conditions and the state of the economic environment. Living standards, unemployment, business cycles, and inflation are outcomes that matter. Almost everyone wants growing living standards, high employment, and low unemployment, as well as an avoidance of recessions and inflation. These are known as the targets of policy. 'Good' values of these variables are what governments would like to achieve. Fiscal and monetary policies (government spending, taxes, interest rates, and the money supply) are not valued so much for their own sake: rather, they are the instruments of policy and are valued for the effect they have on the targets. Instruments are the variables that the government can change directly in order to change the targets, which are the things that it would like to change. The macroeconomic policy problem is to choose appropriate values of the policy instruments in order to achieve the best possible combination of the outcomes of the targets. This is a continually changing problem, because the targets are perpetually being affected by shocks from various parts of the world economy. 76 Text 4. VALUE ADDED AS OUTPUT National output and national income are central topics in macroeconomics. For the most part we measure both of these by gross domestic product, which is usually shortened to GDP. The reason that getting a total for the nation's output is not quite as straightforward as it may seem at first sight is that one firm's output is often another firm's input. A maker of clothing buys cloth from a textile manufacturer and buttons, zips, thread, pins, hangers, etc., from a range of other producers. Most modern manufactured products have many ready-made inputs. A car or aircraft manufacturer, for example, has hundreds of component suppliers. Production occurs in stages: some firms produce outputs that are used as inputs by other firms, and these other firms in turn produce outputs that are used as inputs by yet other firms. If we merely added up the market values of all outputs of all firms, we would obtain a total that was greatly in excess of the value of the economy's actual output. The error that would arise in estimating the nation's output by adding all sales of all firms is called double counting. 'Multiple counting' would be a better term, since, if we added up the values of all sales, the same output would be counted every time that it was sold from one firm to another. The problem of double counting is resolved by distinguishing between two types of output. Intermediate goods and services are the outputs of some firms that are in turn used as inputs for other firms. Final goods and services are goods that are not used as inputs by other firms in the period of time under consideration. The term final demand refers to the purchase of final goods and services for consumption, for investment (including inventory accumulation), for use by governments, and for export. It does not include goods and services that are purchased by firms and used as inputs for producing other goods and services. If the sales of firms could be readily separated into sales for final use and sales for further processing by other firms, measuring total output would still be straightforward. Total output would equal the value of all final goods and services produced by firms, excluding all intermediate goods and services. However, when a textile manufacturer sells a piece of cloth, it does not necessarily know whether it is being purchased by a fashion house, which will sell it on in the form of a dress, or is being purchased by a consumer for use as, say, a sofa cover. Thus, at the point of sale it is not always obvious if this is a final or intermediate sale. The problem of double counting must therefore be resolved in some other manner. To avoid double counting, statisticians use the important concept of value added. Each firm's value added is the value of its output minus the value of the inputs that it purchases from other firms (which were in turn the outputs of those other firms). Thus, a steel mill's value added is the value of its output minus the value of the ore that it buys from the mining company, the value of the electricity and other fuel that it uses, and the values of all other inputs that it buys from other firms. A bakery's value added is the value of the bread and cakes it produces minus the value of the flour and other inputs that it buys from other firms. 77 The total value of a firm's output is the gross value of its output. The firm's value added is the net value of its output. It is this latter figure that is the firm's contribution to the nation's total output. It is what its own efforts add to the value of what it takes in as inputs. Value added measures each firm's own contribution to total output, the amount of market value that is produced by that firm. Its use avoids the statistical problem of double counting. The sum of all values added in an economy is a measure of the economy's total output. This measure of total output is called gross value added. It is a measure of all final output that is produced by all productive activity in the economy. Text 5. THE CIRCULAR FLOW OF INCOME, OUTPUT, AND SPENDING Figure 9.2 gives a stylized version of how income and expenditure interact with each other in what is called a circular flow diagram. To begin with, consider an economy that is made up solely of domestic individuals and domestic firms. For a moment we assume that the economy has no imports or exports and no government. The individuals provide labour for the firms and they buy the firms' output. The income that flows to individuals is represented by line in the figure running up the left-hand side of the diagram, and their spending on the final output of firms is represented by the line running down the right-hand side. National output (or national income) can be measured either from the spending side in terms of spending on final goods produced, or on the income side. These incomes of resource owners can be measured either as the sum of values added in the economy or as the sum of individual incomes. In practice, final spending is not made up simply of individuals' consumption spending, so when we approach the explanation of GDP from the spending side we need to add in investment spending, government consumption, and exports. Figure 9.2. An economy is made up of income and spending flows between firms and households The circular flow diagram shows how incomes give rise to spending which gives rise to output which gives rise to incomes. 78 Withdrawals, or leakages, arise from income that is not passed on in the circular flow through spending; while injections are spending that does not arise out of incomes but is exogeneous. Text 6. THE MEASURES OF NATIONAL INCOME AND NATIONAL PRODUCT The measures of national income and national product that are used derive from an accounting system that has recently been standardized by international agreement and is thus common to most major countries. It is known as the System of National Accounts. A more detailed specification of this accounting system applies to all EU member states under the European System of Accounts 1995. These accounts have a logical structure, based on the simple yet important idea that all output must be owned by someone. So whenever national output is produced, it must generate an equivalent amount of claims to that output in the form of national income. Corresponding to the two sides of the circular flow in Figure 9.2 are two ways of measuring national income: by determining the value of what is produced and the value of the income claims generated by production. Both measures yield the same total, which is called gross domestic product (GDP). When it is calculated by adding up the total spending for each of the main components of final output, the result is called GDP spending-based. When it is calculated by adding up all the incomes generated by the act of production, it is called GDP income-based. All value produced in the form of output must also generate a claim to the income generated in the process of creating that value. For example, any spending you make when you buy a TV set must also be received by the supplier of that set. The value of what you spend is the spending; the value of the product sold to you is the output. Thus, the two values calculated on income and spending bases are identical conceptually, and they differ in practice only because of errors of measurement. Any discrepancy arising from such errors is then reconciled so that one common total is given as the measure of GDP. Both calculations are of interest, however, because each gives a different and useful breakdown. Also, having two independent ways of measuring the same quantity provides a useful check on statistical procedures and on unavoidable errors in measurement. Text 7. GDP SPENDING-BASED GDP spending-based for a given year is calculated by adding up the spending going to purchase the final output produced in that year. Total spending on final output is expressed in the National Accounts as the sum of three broad categories of spending: consumption, investment, and net exports. Consumption is further divided into the consumption spending of government and that of private individuals (and non-profit organizations serving households). So there are four 79 important categories of spending that we will discuss: private consumption, government consumption, investment, and net exports. Private consumption spending (C) includes spending by individuals on goods and services produced and sold to their final users during the year—services such as haircuts, medical care, and legal advice; nondurable goods such as fresh meat, clothing, cut flowers, and fresh vegetables; and durable goods such as cars, television sets, and microwave ovens. When governments provide goods and services that their citizens want, such as health care and street lighting, it is obvious that they are adding to the sum total of valuable output in the same way as do private firms that produce cars and CDs. Spending by the government where the consumption cannot be assigned to specific individuals is called in the National Accounts collective government final consumption. In macroeconomics we lump together individual government final consumption and collective government final consumption into one term: government consumption, sometimes just called government spending. It is important to recognize that only government spending (G) on currently produced goods and services is included as part of GDP. A great deal of government spending is not a part of GDP. For example, when the Department of Health and Social Security (DHSS) makes a payment to an old-age pensioner, the government is not purchasing any currently produced goods or services from the retired. The payment itself adds neither to employment nor to total output. The same is true of payments on account of unemployment benefit, income support, student grants, and interest on the National Debt (which transfers income from taxpayers to holders of government bonds). All such payments are examples of transfer payments, which is government spending not made in return for currently produced goods and services. Investment spending (I) is denned as spending on the production of goods not for present consumption, but rather for future use. The goods that are created by this spending are called investment (or capital) goods. Investment spending can be divided into three categories: changes in inventories, fixed capital formation, and the net acquisition of valuables. Almost all firms hold stocks of their inputs and their own outputs. These stocks are known as inventories. Inventories of inputs and unfinished materials allow firms to maintain a steady stream of production in spite of short-term fluctuations in the deliveries of inputs bought from other firms. Inventories of outputs allow firms to meet orders in spite of temporary fluctuations in the rate of output or sales. Modem 'just-in-time' methods of production pioneered by the Japanese aim to reduce inventories held by manufacturing plants to nearly zero by delivering inputs just as they are needed. Most of the economy, however, does not achieve this level of efficiency and never will. Retailing, for example, would certainly not be improved if shops held no stocks. An accumulation of stocks and unfinished goods in the production process counts as current investment because it represents goods produced (even if only half-finished) but not used for current consumption. All of gross investment is included in the calculation of GDP. This is because all investment goods are part of the nation's total output, and their 80 production creates income (and employment) whether the goods produced are a part of net investment or are merely replacement investment. The fourth category of aggregate spending, and one that is very important to the economy, arises from foreign trade. How do imports and exports affect the calculation of GDP? A country's GDP is the total value of final goods and services produced in that country. It is convenient to group actual imports and actual exports together as net exports. Net exports are defined as total exports of goods and services minus total imports of goods and services (X- IM), which will also be denoted by NX. When the value of exports exceeds the value of imports, the net export term is positive. When the value of imports exceeds the value of exports, the net export term is negative. Total spending The spending-based measure of gross domestic product at market prices is the sum of the four spending categories that we have discussed above; in symbols, GDP = C + I+ G+ (X - IM). GDP spending-based is the sum of private consumption, government consumption, investment, and net export spending on currently produced goods and services. It is GDP at market prices. Text 8. GDP INCOME – BASED The production of a nation's output generates income. Labour must be employed, land must be rented, and capital must be used. The calculation of GDP from the income side involves adding up the income claims of owners of resource inputs (land, labour, capital, etc.) so that all of that value is accounted for. National income accountants distinguish three main categories of income: operating surplus, mixed incomes, and compensation of employees. Operating surpluses are net business incomes after payment has been made to hired labour and for material inputs but before direct taxes (such as corporation tax) have been paid. Direct taxes are those taxes levied on individuals or firms, usually in relation to their income. Operating surpluses are in large part the profits of firms, but also include the financial surplus of organizations other than companies, such as universities. Some profits are paid out as dividends to owners of firms; the rest are retained for use by firms. The former are called distributed profits, and the latter are called undistributed profits or retained earnings. Both distributed and undistributed profits are included in the calculation of GDP. Mixed incomes. This category covers the many people who are earning a living by selling their services or output but are not employed by any organization. It includes some consultants and those who work on short contracts but are not formally employees of an incorporated business; they are self-employed individuals running sole-trader businesses. Also included are some partnerships where the partners own the business. The reason why the incomes of this group are 81 referred to as mixed incomes is that it is not clear what proportion of their earnings is equivalent to a wage or salary and what proportion is the profit or surplus of the business. They are a mixture of the two. Compensation of employees. This is wages and salaries (usually just referred to as wages). It is the payment for the services of labour. Wages include take-home pay, taxes withheld, national insurance contributions, pension fund contributions, and any other fringe benefits. In other words, wages are measured gross. In total, wages represent that part of the value of production that is attributable to hired labour. Text 9. GROSS NATIONAL PRODACT While GDP measures the output, and hence the income, that is produced in this country, the gross national income (GNI) measures the income that is received by this country. To convert GDP into GNI, it is necessary to add three terms that combine to account for the difference between the income received by this country and the income produced in this country. The first term is employees' compensation receipts from the rest of the world minus payments to the rest of the world. Thus, if a London-based consultant sells her services to a French firm, the income received will contribute to UK GNI but will be part of French GDP. The second term is (minus) net taxes on production paid to the rest of the world plus subsidies received from the rest of the world. The logic of this is that we are measuring GNI (like GDP) at market prices. If some element of the market prices paid is an indirect tax that generates revenue for a foreign government, then that tax represents a loss of income for the domestic economy as a whole and reduces domestic gross national income. Equally, if the product is subsidized by a foreign government, then this raises domestic incomes by enabling us to consume a given amount of goods at lower prices. The third component of the difference between GDP and GNI is property and entrepreneurial income receipts from the rest of the world minus payments to the rest of the world. If, for example, you live in Manchester and own a holiday home in Spain that you rent out for part of the year, the revenue earned will count as part of GDP in Spain (as it is produced there), but the income accrues to a UK resident so it adds to UK GNI. Similarly, many UK firms have subsidiaries located in other countries. The value added of those subsidiaries counts as part of GDP in the host country, but profits remitted to the parent count as part of the UK's GNI. Conversely, a Japanese firm located in the UK contributes all its value added to UK GDP, but profits remitted back to Japan are deducted from GDP in order to arrive at GNI (as they are not part of UK income). Total output produced in the economy, measured by GDP, differs from total income received, measured by CNI, because of net income from abroad. It is important to note that the term gross national income was introduced as recently as 1998 to replace the term gross national product or GNP. GNI and GNP are conceptually identical. GDP and GNI (or GNP) at market prices are the most commonly used concepts of national output and national income. Once we 82 move on to theory in the next chapter, we shall ignore the small difference between GDP and GNI and refer to GDP at all times unless stated otherwise. *** Other income concepts Personal income is income that is earned by or paid to individuals, before allowing for personal income taxes on that income. Some personal income goes on taxes, some goes on savings, and the rest goes on consumption. Personal disposable income is the amount of current income that individuals have available for spending and saving; it is personal income minus personal income taxes and national insurance contributions. Personal disposable income is GNI minus any part of it that is not actually paid to persons (such as retained profits of companies) minus personal income taxes plus transfer payments received by individuals. Text 10. REAL AND NOMINAL MEASURES The information provided by National Accounts data is useful, but unless it is carefully interpreted it can be misleading. Furthermore, each of the specific measures gives different information. Each may be the best statistic for studying a particular range of problems, but it is important to understand these differences if you are going to use the data for analytical purposes. Here we discuss some of the caveats to bear in mind. It is important to distinguish between real and nominal measures of national income and output. When we add up money values of outputs, spending, or incomes, we end up with what are called nominal values. Suppose that we found that a measure of nominal GDP had risen by 70 per cent between 2000 and 2010. If we wanted to compare real GDP in 2010 with that in 2000, we would need to determine how much of that 70 per cent nominal increase was due to increases in the general level of prices and how much was due to increases in quantities of goods and services produced. Although there are many possible ways of doing this, the basic principle is always the same. It is to compute the value of output, spending, and income in each period by using a common set of base-period prices. When this is done, we speak of real output, spending, or income as being measured in constant prices or, say, 2000 prices. GDP valued at current prices (i.e. money GDP) is a nominal measure. GDP valued at base-period prices is a real measure of the volume of national output and national income. Any change in nominal GDP reflects the combined effects of changes in quantities and changes in prices. However, when real income is measured over different periods by using a common set of base-period prices, changes in real income reflect only changes in real output. 83 If nominal and real GDP change by different amounts over some timeperiod, this must be because prices have changed over that period. Comparing what has happened to nominal and real GDP over the same period implies the existence of a price index measuring the change in prices over that period. We say 'implies' because no price index was used in calculating real and nominal GDP. However, an index can be inferred by comparing these two values. Such an index is called an implicit price index or an implicit deflator. It is defined as follows: Implicit deflator = GDP at current prices GDP at base-period prices x 100 %. The implicit GDP deflator is the most comprehensive index of the price level because it covers all the goods and services that are produced by the entire economy. Although some other indexes use fixed weights, or weights that change only periodically, implicit deflators are variable-weight indexes. They use the current year's 'bundle' of production to compare the current year's prices with those prevailing in the base period. Thus, the 2000 deflator uses 2000 output weights, and the 2005 deflator uses 2005 output weights. Exercises: A) B) C) D) E) F) G) H) I) J) 1.

The deposit is a liability of the bank. It is the money owed to depositors. In turn the bank lends money to firms, households, or governments wishing to borrow. Commercial banks are financial intermediaries with a government license to make loans and issue deposits, including deposits against which cheques can be written. Major important banks in most countries are included in the clearing system in which debts between banks are settled by adding up all the transactions in a 87 given period and paying only the net amounts needed to balance inter-bank accounts. The balance sheet of a bank includes assets and liabilities. We begin by discussing the asset side of the balance sheet. Cash assets are notes and coins kept in their vaults and deposited with the Central Bank. The balance sheet also shows money lent out or used to purchase short-term interest-earning assets such as loans and bills. Bills are financial assets to be repurchased by the original borrower within a year or less. Loans refer to lending to households and firms and are to be repaid by a certain date. Loans appear to be the major share of bank lending. Securities show bank purchases of interest-bearing long-term financial assets. These can be government bonds or industrial shares. Since these assets are traded daily on the Stock Exchange, these securities seem to be easy to cash whenever the bank wishes, though their price fluctuates from day to day. We now examine the liability side of the balance sheet which includes mainly, deposits. The two most important kinds of deposits are sure to be sight deposits and time deposits. Sight deposits can be withdrawn on sight4 whenever the depositor wishes. These are the accounts against which we write cheques, thus withdrawing money without giving the bank any warning. Therefore, most banks do not pay interest on sight deposits, or chequing accounts. Before time deposits can be withdrawn, a minimum period of notification must be given within which banks can sell off some of their high-interest securities or call in some of their high-interest loans in order to have the money to pay out depositors. Therefore, banks usually pay interest on time deposits. Apart from deposits banks usually have some other liabilities as, for instance, deposits in foreign currency, cheques in the process of clearance and others. Exercises: I.

LIQUIDITY Liquidity is determined by the speed and certainty with which an asset can be converted into cash (notes and coins) in order to be used as a means of payment. The quicker an asset can be converted into cash, the more liquid it is. Therefore, money is sure to be the most liquid asset of all since it is widely accepted as a medium of exchange, while durable and highly specific assets such as machinery are the least liquid as such asset cannot be converted into money without finding a buyer and determining the value of the asset to be sold. A bank's assets can also be characterized in terms of their liquidity. Loans to households and firms do not appear to be very liquid forms of bank lending, for the borrower may not be able to repay the sum owed to the bank whenever the bank demands. Securities including government bonds and shares of firms, though traded on the stock exchange, cannot be relied upon for a certain amount of cash as their prices are known to fluctuate from day to day. Therefore, financial investment in securities seems also to be illiquid. Of all bank assets cash and short-term market loans are sure to be the most liquid ones.

RESERVE REQUIREMENT AS A TOOL OF MONEY POLICIES A banker would like his money holdings to be reduced to a minimum, since they produce no income. But there is always an important reason for the banker to hold his money balances at a certain level. The Central Bank makes him hold a certain share of his total balances in reserve. These reserve balances must be in the form of cash or of deposits made by commercial banks with a certain authorized bank. Most of reserve balances are known to be in the form of deposits. Setting the reserve requirements, the Central Bank can regulate money circulation and money supply in an economy. The Central Bank can, on the one hand, increase commercial banks' reserves by direct intervention. One way of doing this is by the so-called open market operations: it buys government bonds from the public; thus, the money that goes to the public in payment for these bonds will eventually be deposited with commercial banks, most likely in interest-earning deposits. Having been deposited with a bank, money stops being money, but it represents a net addition to reserve balances capable of supporting loan transactions several times their own value. For this reason, the Central Bank is said to have supplied "high powered" money to commercial banks. On the other hand, selling bonds to the public, the Bank can reduce the banking system's reserves and thus make the money supply reduce. Open market operations are not the only method of direct reserve intervention. Another way for the Central Bank to increase money in circulation is to make loans to commercial banks who in turn lend out to the public the money to be used for daily expenditure. Finally, the Central Bank can change the money supply without affecting the amount of reserves to be held by commercial banks. It can do this simply having changed the reserve requirement. Having been decreased from 20 percent to 10 percent, the reserve balances will actually double their capacity to support transactions. As a result, maintaining the same reserve balances, banks get a chance of handling loan transactions twice as large as before. Thus, the three monetary policies a Central Bank can implement are as follows: 1. Open market operations. 2. Loans to commercial banks. 3. Changes in reserve requirements. 90 Text 4. THE SUPPLY AND THE DEMAND OF MONEY In a modern economy the supply of money is determined by the interaction of the banking system and the non-bank private sector. In most major countries the authorities implement monetary policy by setting interest rates and letting the money stock be determined by how much is demanded at that interest rate. The amount of wealth that everyone in the economy wishes to hold in the form of money balances is called the demand for money. Because people can choose how to divide their given stock of wealth between money and bonds, it follows that if we know the demand for money, we also know the demand for bonds. With a given level of wealth, a rise in the demand for money necessarily implies a fall in the demand for bonds; if people wish to hold £1 billion more money, they must wish to hold £1 billion less of bonds. It also follows that, if households are in equilibrium with respect to their money holdings, they are in equilibrium with respect to their bond holdings. When we say that in first quarter of 2007 the quantity of money demanded was £1,300 billion (the approximate value of the broad money stock, M4, at that time), we mean that at that time the public wished to hold money balances that totalled £1,300 billion. But why do firms and individuals wish to hold money balances at all? There is a cost to holding any money balance. The money could have been used to purchase bonds, which earn higher interest than does money. For the present we assume no ongoing inflation, so there is no difference between real and nominal interest rates. The opportunity cost of holding any money balance is the extra interest that could have been earned if the money had been used instead to purchase bonds. Clearly, money will be held only when it provides services that are valued at least as highly as the opportunity cost of holding it. Three important services that are provided by money balances give rise to three motives for holding money: the transactions, precautionary, and speculative motives. The transactions motive. Most transactions require money. Money passes from consumers to firms to pay for the goods and services produced by firms; money passes from firms to employees to pay for the labour services supplied by workers to firms. Money balances that are held to finance such flows are called transactions balances. In an imaginary world in which the receipts and disbursements of consumers and firms were perfectly synchronized, it would be unnecessary to hold transactions balances. If every time a consumer spent £10 she received £10 as part payment of her wages, no transactions balances would be needed. In the real world, however, receipts and payments are not perfectly synchronized. Consider the balances that are held because of wage payments. Suppose, for purposes of illustration, that firms pay wages every Friday and that employees spend all their wages on goods and services, with the spending spread out evenly over the week. Thus, on Friday morning firms must hold balances equal to the weekly wage bill; on Friday afternoon the employees will hold these balances. 91 Over the week, workers' balances will be drawn down as a result of their purchasing goods and services. Over the same period, the balances held by firms will build up as a result of selling goods and services until, on the following Friday morning, firms will again have amassed balances equal to the wage bill that must be met on that day. The transactions motive arises because payments and receipts are not synchronized. What determines the size of the transactions balances to be held? It is clear that in our example total transactions balances vary with the value of the wage bill. If the wage bill doubles for any reason, the transactions balances held by firms and households for this purpose will also double, on average. As it is with wages, so it is with all other transactions: the size of the balances held is positively related to the value of the transactions. It is the average value of money balances that people choose to hold over a particular period that is relevant for macroeconomics, but we need to know how money demand relates to GDP rather than to total transactions. In fact, the value of all transactions exceeds the value of the economy's final output. When the miller buys wheat from the farmer and when the baker buys flour from the miller, both are transactions against which money balances must be held, although only the value added at each stage is part of GDP. Generally there will be a stable, positive relationship between transactions and GDP. A rise in GDP also leads to a rise in the total value of all transactions and hence to an associated rise in the demand for transactions balances. This allows us to relate transactions balances to GDP. The larger the value of GDP, the larger is the value of transactions balances that will be held. The precautionary motive. Many reasons for spending arise unexpectedly, such as when your car breaks down, or you have to make an unplanned journey to visit a sick relative. As a precaution against cash crises, when receipts are abnormally low or disbursements are abnormally high, firms and individuals carry money balances. Precautionary balances provide a cushion against uncertainty about the timing of cash flows. The larger such balances are, the greater is the protection against running out of money because of temporary fluctuations in cash flows. The seriousness of the risk of a cash crisis depends on the penalties that are inflicted for being caught without sufficient money balances. A firm is unlikely to be pushed into insolvency, but it may incur considerable costs if it is forced to borrow money at high interest rates in order to meet a temporary cash crisis. The precautionary motive arises because individuals and firms are uncertain about the degree to which payments and receipts will be synchronized. The protection provided by a given quantity of precautionary balances depends on the volume of payments and receipts. A £100 precautionary balance provides a large cushion for a person whose volume of payments per month is £800 and a small cushion for a firm whose monthly volume is £250,000. To 92 provide the same degree of protection as the value of transactions rises, more money is necessary. The precautionary motive, like the transactions motive, causes the demand for money to vary positively with the money value of GDP. For most purposes the transactions and precautionary motives can be merged, as they both show that desired money holdings are positively related to GDP. Indeed, they both show money being held in relation to transactions, either planned or potential. The speculative motive Money can be held for its characteristics as an asset. Firms and individuals may hold some money in order to provide a hedge against the uncertainty inherent in fluctuating prices of other financial assets. Money balances held for this purpose are called speculative balances. This motive was first analysed by Keynes. Professor James Tobin, the 1981 Nobel Laureate in economics, developed the modern analysis. Any holder of money balances forgoes the extra interest income that could be earned if bonds were held instead. However, market interest rates fluctuate, and so do the market prices of existing bonds (whose present values depend on the interest rate). Bonds are risky assets, because their prices fluctuate. Many individuals and firms do not like risk; they are said to be risk-averse. In choosing between holding money and holding bonds, wealth-holders must balance the extra interest income that they could earn by holding bonds against the risk that bonds carry. At one extreme, if individuals hold all their wealth in the form of bonds, they earn extra interest on their entire wealth, but they also expose their entire wealth to the risk of changes in the price of bonds. At the other extreme, if people hold all their wealth in the form of money, they earn less interest income, but they do not face the risk of unexpected changes in the price of bonds. Wealth-holders usually do not take either extreme position. They hold part of their wealth as money and part of it as bonds; that is, they diversify their holdings. The fact that some proportion of wealth is held in money and some in bonds suggests that, as wealth rises, desired money holdings will also rise. The speculative motive implies that the demand for money varies positively with wealth. Although one individual's wealth may rise or fall rapidly, the total wealth of a society changes only slowly. For the analysis of short-term fluctuations in GDP, the effects of changes in wealth are fairly small, and we will ignore them for the present. Specific individuals may undergo large wealth changes in response to bond price changes, but with inside wealth the total effect is small. When lenders gain, borrowers lose; and when lenders lose, borrowers gain. Over the long term, however, variations in aggregate wealth can have a major effect on the demand for money. Wealth that is held in cash or deposits earns less interest than could be earned by holding bonds; hence the reduction in risk involved in holding money carries an opportunity cost in terms of interest earnings forgone. The speculative motive leads individuals and firms to add to their money holdings until the reduction in risk obtained by the last pound added is just balanced (in each wealth93 holder's view) by the cost in terms of the interest forgone on that pound. A fall in the rate of return on bonds for the same level of risk will encourage people to hold more of their wealth as money and less in bonds. A rise in their rate of return for a given level of risk will cause people to hold more bonds and less money. The speculative motive implies that the demand for money will be negatively related to the rate of interest. The precautionary and transactions motives may also be negatively related to interest rates at the margin, because higher returns on bonds encourage people to economize on their money holding. However, in practice we only observe total money holdings, so we cannot distinguish the components held for different motives. Hence demand for money, as a whole, is likely to be positively related to GDP and wealth, and negatively related to the interest rate. Text 5. REAL AND NOMINAL MONEY BALANCES The money supply is a nominal quantity, but it is important to distinguish demand for real money balances from nominal money demand. Real money demand is the number of units of purchasing power that the public wishes to hold in the form of money balances. For example, in an imaginary one-product (wheat) economy, the number of bushels of wheat that could be purchased with the money balances held would be the measure of their real value. In a more complex economy it could be measured in terms of the number of 'baskets of goods', represented by a price index such as the RPI, that could be purchased with the money balances held. When we speak of the demand for money in real terms, we speak of the amount demanded in constant pounds (that is, with a constant price level): The real demand for money (or the demand for real money balances) is the nominal quantity demanded divided by the price level. In the twenty-four years from March 1982 to February 2006, on the M4 definition, the nominal quantity of money balances held in the country increased nearly ten-fold, from around £140 billion to around £1,333 billion. Over the same period, however, the price level, as measured by the RPI, approximately trebled. This tells us that the real quantity of money rose from £140 billion to about £500 billion, measured in constant 1982 prices, roughly a three-fold increase. So far we have held the price level constant, and so we have identified the determinants of the demand for real money balances as real GDP, real wealth, and the interest rate. Now suppose that, with the interest rate, real wealth, and real GDP held constant, the price level doubles. Because the demand for real money balances will be unchanged, the demand for nominal balances must double. If the public previously demanded £300 billion in nominal money balances, it will now demand £600 billion. This keeps the real demand unchanged at £600/2 = £300 billion. The money balances of £600 billion at the new, higher price level represent exactly the same purchasing power as £300 billion at the old price level. Other things being equal, the nominal demand for money balances varies in proportion to the price level; when the price level doubles, desired nominal money balances also double. 94 Text 6. INFLATION Inflation is generally defined as a persistent rise in the general price level with no corresponding rise in output, which leads to a corresponding fall in the purchasing power of money. In this section we shall look briefly at the problems that inflation causes for business and consider whether there are any potential benefits for anicnterprise from an inflationary period. Inflation varies considerably in its extent and severity. Hence, the consequences for the business community differ according to circumstances. Mild inflation of a few per cent each year may pose few difficulties for business. However, hyperinflation, which entails enormously high rates of inflation, can create almost insurmountable problems for the government, business, consumers and workers. In post-war Hungary, the cost of having was published each day and workers were paid daily so as to avoid the value of their earnings falling. Businesses would have experienced great difficulty in costing and pricing their production while the incentive for people to save would have been removed. Economists argue at length about the causes of, and «cures» for, inflation. They would, however, recognize that two general types of inflation exist: • Demand-pull inflation • Cost-push inflation Demand-pull inflation occurs when demand for a nation's goods and services outstrips that nation's ability to supply these goods and services. This causes prices to rise generally as a means of limiting demand to the available supply. An alternative way that we can look at this type of inflation is to say that it occurs when injections exceed withdrawals and the economy is already stretched (i.e. little available labour or factory space) and there is little scope to increase further its level of activity. Cost-push Inflation. Alternatively, inflation can be of the cost-push variety. This takes place when firms face increasing costs. This could be caused by an increase in wages, the rising costs of imported raw materials and components or companies pushing up prices in order to improve their profit margins. Exercises: 1.

Read the texts and give a short summery of the texts. Text 1. GOVERNMENT SPENDING Government consumption is part of GDP. When the government hires a civil servant, buys a paper clip, or purchases fuel for the navy, it is directly adding to the demand for the economy's current output of goods and services. Thus, desired government purchases, G, are part of aggregate spending. The other part of government spending, transfer payments, also affects desired aggregate spending, but only indirectly. Consider, for example, state pensions or unemployment benefit. These are payments (transfers) made by government to individuals, who will spend at least some of the money. Since that spending is recorded as personal consumption, we do not want to count it twice by recording it under G as well. Government transfer payments affect aggregate spending only through the effect that these payments have on personal disposable income. Transfer payments increase disposable income, and increases in 97 disposable income, via the consumption function, increase desired consumption spending. This distinction (between transfers and government consumption) is important when it comes to issues such as determining the amount of GDP that is accounted for by government. Measuring the size of government to include transfers makes it look as though government's share of GDP is much bigger than it really is. However, looking only at G makes the government's revenue needs look smaller than they are, since transfers must be financed by taxes or borrowing, just as spending on goods and services must be. In what follows, government spending always excludes transfers, unless the contrary is stated. Text 2. TAX REVENUES Tax revenues may be thought of as negative transfer payments in their effect on desired aggregate spending. Tax payments reduce disposable income relative to national income; transfers raise disposable income relative to national income. For the purpose of calculating the effect of government policy on desired consumption spending, it is the net effect of the two that matters. We define net taxes to be total tax revenues received by the government minus total transfer payments made by the government, and we denote net taxes as T. (For convenience, when we use the term 'taxes', we will mean net taxes unless we explicitly state otherwise.) Since transfer payments are smaller than total taxes, net taxes are positive, and personal disposable income is less than national income. TEXT 3. THE BUDGET BALANCE The budget balance is the difference between total government revenue and total government spending, or equivalently net taxes minus government spending, T- G. When revenues exceed spending, the government is running a budget surplus. The government will then reduce the national debt, since the surplus funds will be used to pay off old debt. When spending exceeds revenues, as it has for much of the period since the Second World War (1969-70, 1988-9, and 19982001 were the only exceptions between 1945 and 2005), the government is running a budget deficit. The government must then add to the national debt, since it must borrow to cover its deficit. When the budget surplus (and deficit) is zero, the government has a balanced budget. Since the budget deficit is simply a negative budget surplus, we generally use the term 'budget surplus' to cover both cases, so bear in mind that the budget surplus can be negative. TEXT 4. TAX AND SPENDING FUNCTION We treat government spending as exogenous; that is, it does not vary with GDP. The government is assumed to decide how much it wishes to spend in real terms and to hold to these plans whatever the level of GDP. We also treat tax rates 98 as exogenous. The government sets its tax rates and does not vary them as GDP varies. This makes tax revenues endogenous. As GDP rises with given tax rates, the tax revenue will rise. For example, when incomes rise, people pay more total tax, even if tax rates are unchanged. Table 11.1 The budget surplus function (£ million) GDP Government Net taxed Government spending (G) (T=0,1 GDP) surplus (T-G) 500 170 50 -120 1.000 170 100 -70 1.750 170 175 5 2.000 170 200 30 3.000 170 300 130 4.000 170 400 230 Table 11.1 and Figure 11.1 illustrate these assumptions with a specific example. They show the size of the government's surplus when its desired purchases (G) are constant at £170 million and its net tax revenues are equal to 10 per cent of GDP (national income). Notice that the government budget surplus (or public saving) increases with GDP. This relationship occurs because net tax revenues rise with GDP but, by assumption, government spending does not. The slope of the budget surplus function is just equal to the income tax rate. Figure 11.1 Budget surplus function For given tax rates, the government budget surplus (public saving) increases as GDP rises and falls as GDP falls. Text 5. FISCAL POLICY Fiscal policy involves the use of government spending and tax policies to influence total desired spending in order to achieve any specific goal set by the government. Since government spending increases aggregate desired spending and taxation decreases it, the directions of the required changes in spending and taxation are generally easy to determine once we know the direction of the desired change in GDP. But the timing, magnitude, and mixture of the changes pose more difficult issues. Any policy that attempts to stabilize GDP at or near any desired level (usually potential GDP) is called stabilization policy. 99 If the government has some target level of GDP, it can use its taxation and spending as instruments to push the economy towards that target. First, suppose the economy is in a serious recession. The government would like to increase GDP. The appropriate fiscal tools are to raise spending and/or to lower tax rates. Second, suppose the economy is 'overheated'. Without worrying too much about the details, just assume that the current level of GDP is higher than the target level that the government judges to be appropriate. What should the government do? The fiscal tools at its command are to lower government spending and to raise tax rates, both of which will have a depressing effect on GDP. The proposition that governments can alleviate recessions by deliberately stimulating aggregate demand created a major revolution in economic thought. This is still known as the Keynesian revolution. According to Keynesian theory, governments can use fiscal policy to increase aggregate spending by increasing government spending or reducing taxes (or both). The aggregate spending model of national income and output determination predicts that GDP can get stuck at a level below its full potential. It also suggests how fiscal policy might be used to return an economy to its potential level of GDP. Text 6. GOVERNMENT OBJECTIVES Governments have multiple objectives: 1 To protect life and property by exercising a monopoly of force and establishing property rights 2. To improve economic efficiency by addressing the various causes of market failure 3. To protect the environment 4. To achieve some accepted standard of equity 5. To protect individuals from others and from themselves 6. To influence the rate of economic growth 7. To stabilize the economy against income and price-level fluctuations Markets generate reasonably efficient allocations of the nation's resources because, most of the time, the information that they need to allow them to perform well, even if not optimally, is derived from agents' desires to improve their private circumstances. No one should be surprised, therefore, that markets do not efficiently allocate resources towards achieving such broad social goals as establishing an 'equitable' distribution of income and promoting shared community values. Markets do not directly foster these goals, precisely because individuals do not seek to achieve them when they are purchasing goods and services in markets. Instead, they look to the political system to achieve desired outcomes in this respect. The distribution of income. An important characteristic of any market economy is the distribution of income that it determines. People whose skills are scarce relative to supply earn large incomes, whereas people whose skills are plentiful relative to supply earn much less. 100 Differentials in earnings serve the important function of motivating people to adapt. The advantage of such a system is that individuals can make their own decisions about how to alter their behaviour when market conditions change. The disadvantage is that temporary rewards and penalties are dealt out as a result of changes in market conditions that are beyond the control of the affected individuals. The resulting differences in incomes will seem inequitable to many— even though they are the incentives that make markets work. Concerns about equity have two dimensions: horizontal and vertical. Horizontal equity means that people in similar circumstance should be treated similarly. Although this type of equity appeals to many people as desirable, it is not always a goal of government policies. For example, people who are exposed to similar natural risks are given more government assistance when they are planting crops than when they are mining ore, cutting trees, or extracting oil. This may be because farmers have more political power than others, or it may stem from a gut feeling on the part of the electorate that food production is more basic than any other economic activity. Vertical equity means treating people in different economic situations differently in order to reduce inequalities between them. Figure 11.2 shows what is called a Lorenz curve. It shows how much of total income is received by various proportions of the nation's income earners. It indicates how total income is distributed among individuals or groups. The further the curve bends away from the diagonal, the more unequal are the incomes of the people in society. The curve shows, for example, that the bottom 20 per cent of all individuals received only 2.6 per cent of all taxable income earned, while the bottom 80 per cent received only 51 per cent of total taxable income. The remaining 49 per cent went to the top 20 per cent of incomeearners. The income shown in the figure is taxable income, measured before taxes and benefits. After the impact of taxes and benefits is included, the share of the bottom 20 per cent rises to 9 per cent and the share of the top 20 per cent falls to 39 per cent. Thus, the tax-benefit system has the effect of substantially narrowing the large disparities in the distribution of income between the various income classes. Figure 11.2 A Lorenz curve of individual pre-tax income Redistributive policies are of two general types. Some, such as the progressive income tax, are concerned with vertical equity. They seek to alter the size distribution of income in quite general ways. High marginal rates of income tax, combined with a neutral spending system that benefits all income groups more or less equally, will narrow income inequalities. Other policies seek to mitigate the effects of markets on particular individuals. They seek not to narrow income gaps in general, but rather to deal 101 with specific unfortunate events. Should farmers bear all the losses associated with the destruction of livestock after an outbreak of foot and mouth or mad cow disease? Should heads of households be forced to bear the full burden of their misfortune if they lose their jobs through no fault of their own? Even if they lose their jobs through their own fault, should they and their families have to bear the whole burden, which may include starvation? Should the ill and the aged be thrown on the mercy of their families? What if they have no families? Policies designed to deal with such situations usually seek horizontal equity in treating similarly all those who fall into some group. Both private charities and a great many government policies are concerned with modifying the distribution of income that results from such things as one's parents' abilities, luck, and how one fares in the labour market. It is sometimes argued that egalitarian economic policy should devote more attention than it does to the distribution of wealth and less to the distribution of income. Wealth confers economic power, and wealth is more unequally distributed than is income. There are two main ways in which inequalities in the distribution of wealth can be reduced. The first is to levy taxes on wealth at the time that wealth is transferred from one owner to another, either by gifts during the lifetime of the owner or by bequest after death. The second method is an annual tax on the value of each person's wealth. Problems arise when government measures designed to improve equity seriously inhibit the efficient operation of the price system. Often the goal of a more equitable distribution conflicts with the goal of a more efficient economy. Text 7. GOVERNMENT POLICIES People can use and even abuse other people for economic gain in ways that the members of society find offensive. Child labour laws and minimum standards of working conditions are responses to such actions. In an unhindered free market, the adults in a household usually decide how much education to buy for their children. Selfish parents might buy no education, while egalitarian parents might buy the same education for all of their children, regardless of their abilities. Members of society may want to interfere in these choices, both to protect the child of the selfish parent and to ensure that some of the scarce educational resources are distributed according to ability rather than a family's wealth. All households are forced to provide a minimum of education for their children, and a number of inducements are offered—through public universities, scholarships, loans, and other means —for talented children to consume more education than they or their parents might choose if they had to pay the entire cost themselves. Members of society, acting through the government, often seek to protect adult (and presumably responsible) individuals not from others, but from themselves. Laws prohibiting the use of heroin, crack cocaine, and other drugs, and laws prescribing the installation and use of car seat belts, are intended primarily to 102 protect individuals from their own ignorance or short-sightedness. This kind of interference in the free choices of individuals is called paternalism. Whether such actions reflect the wishes of the majority in society or the interference of overbearing governments, there is no doubt that the market will not provide this kind of protection. Buyers do not buy what they do not want, and sellers have no motive to provide it. Paternalism is often closely related to merit goods. Merit goods are goods that society, operating through the government, deems to be especially important, or that those in power feel individuals should be encouraged to consume. Housing, education, health care, and cultural amenities such as museums and art galleries are often cited as merit goods. Critics argue that the concept is merely a way of imposing the tastes of an elite group on others. Policies to promote social obligations. In a free-market system, if you can persuade someone else to clean your house in return for £40, both parties to the transaction are presumed to be better off. You prefer to part with £40 rather than to clean the house yourself, and the person you hire prefers to have £40 than to avoid cleaning your house. Normally society does not interfere with people's ability to negotiate mutually advantageous contracts. Most people do not feel this way, however, about activities that are regarded as social obligations. For example, during major wars when military service is compulsory, contracts similar to the one between you and your housekeeper could also be negotiated. Some people, faced with the obligation to do military service, could no doubt pay enough to persuade others to do their tour of service for them. By exactly the same argument as we just used, we can presume that both parties will be better off if they are allowed to negotiate such a trade. Yet such contracts are usually prohibited as a result of widely held values that cannot be expressed in the marketplace. In times of major wars, of the sort that were experienced twice in the twentieth century, military service by all healthy males in the right age group is held to be a duty that is independent of an individual's tastes, income, wealth, or social position. Military service is not the only example of a social obligation. Citizens are not allowed to buy their way out of jury duty or to sell their votes, even though in many cases they could find willing trading partners. Even if the price system allocates goods and services with complete efficiency, members of a society do not wish to rely solely on the market for all purposes, since they have other goals that they wish to achieve. Policies for economic growth. Over the long haul, economic growth is the most powerful determinant of living standards. Whatever their policies concerning efficiency and equity, people who live in economies with rapid rates of growth find their living standards rising on average faster than those of people who live in countries with low rates of growth. Over a few decades, these growth-induced changes tend to have much greater effects on living standards than any policyinduced changes in the efficiency of resource allocation or the distribution of income. 103 For the last half of the twentieth century, most economists viewed growth mainly as a macroeconomic phenomenon related to total savings and total investment. Reflecting this view, most textbooks do not even mention growth in their chapters on microeconomic policy. More recently there has been a shift back to the perspective of earlier economists, who saw technological change as the engine of growth, with individual entrepreneurs and firms as the agents of innovation. This is a microeconomic perspective that is meant to add to, not replace, the macroeconomic stress on capital accumulation. Governments are aware of this microeconomic perspective on growth. Today few microeconomic policies escape being exposed to the question, 'Even if this policy achieves its main goal, will it have unfavourable effects on growth?' Answering yes is not a sufficient reason to abandon a specific policy. But it is a sufficient reason to think again. Is it possible to redesign the policy so that it can still achieve its main objective, while removing its undesirable side-effects on growth? Text 8. TAXATION Taxes and spending are by far the most important items on this list. Governments spend money to achieve many objectives, and that money must be either borrowed or raised through taxes. We leave borrowing aside here, as it is only a temporary measure. Interest must be paid on borrowed money, and if that too is borrowed the total government debt will eventually explode to unmanageable proportions. Sooner or later, all government spending must be paid for out of taxes. Borrowing only postpones the need to tax. As well as providing the revenues needed to finance all of the government's activities, taxes are also used as tools in their own right for a wide range of purposes. They can be used to alter the incentives to which private maximizing agents react, and to alter the distribution of income. Indirect taxes. Taxes are divided into two broad groups, depending on whether it is people or transactions that are taxed. An indirect tax is levied on a transaction and is paid by an individual by virtue of being involved in that transaction. Taxes and stamp duties on the transfer of assets from one owner to another are indirect taxes, since they depend on the assets being transferred. Inheritance taxes, which depend on the size of the estate being inherited and not on the circumstances of the beneficiaries, are another indirect tax. The most important indirect taxes in today's world are those on the sale of currently produced products. These taxes are called excise taxes when they are levied on manufacturers, and sales taxes when they are levied on the sale of goods from retailer to consumer. The EU countries levy a comprehensive tax of this sort on all transactions, whether at the retail, wholesale, or manufacturer's level, called the value added tax (VAT). Value added is the difference between the value of inputs that a firm purchases from other firms and the 104 value of its output. It therefore represents the value that a firm adds by virtue of its own activities. VAT is an indirect tax, because it depends on the value of what is made and sold and not on the wealth or income of the maker or seller. Thus, two self-employed fabric designers, each with a value added of £50,000 in terms of designs produced and sold, would pay the same VAT even if one had no other source of income while the other was independently wealthy. Indirect taxes may be levied in two basic ways. An ad valorem tax is a percentage of the value of the transaction on which it is levied. A specific or perunit tax is a tax expressed as so many pence per unit, independent of the commodity's price. Taxes on cinema and theatre tickets, and on each litre of petrol or alcohol, and on each packet of cigarettes are all specific, indirect taxes. Direct taxes. Taxes in the second broad group are called direct taxes. These are levied on people and vary with the status of the taxpayer. The most important direct tax is the income tax. The personal income tax falls sometimes on the income of households and sometimes separately on each member of the household. It varies with the size and source of the taxpayer's income and various other characteristics, such as marital status and number of dependants. Firms also pay taxes on their incomes. Companies are subject to corporation tax, which is levied on their profits. This is a direct tax, both in the legal sense that the company is an individual in the eyes of the law, and in the economic sense that the company is owned by its shareholders so that a tax on the company is a tax on them. A poll tax, which is simply a lump-sum tax levied on each person, is another direct tax. It is important for many purposes to distinguish average from marginal rates of any tax. The average rate of income tax paid by a person is that person's total tax divided by her income. The marginal rate of tax is the rate she would pay on her next pound's worth of income. Progressivity. The general term for the relation between the level of income and the percentage of income paid as a tax is progressivity. A regressive tax takes a smaller percentage of people's incomes the larger is their income. A progressive tax takes a larger percentage of people's incomes the larger is their income. A proportional tax is the boundary case between the two, since it takes the same percentage of income from everyone. Taxes on food, for example, tend to be regressive, because the proportion of income spent on food tends to fall as income rises. Taxes on alcoholic spirits tend to be progressive, since the proportion of income spent on spirits tends to rise with income. (Taxes on beer, on the other hand, are regressive.) Progressivity can be denned for any one tax or for the tax system as a whole. Different taxes have different characteristics. Inevitably, some will be progressive and some regressive. The impact of a tax system as a whole on high-, middle-, and low-income groups is best judged by looking at the progressivity of the whole set of taxes taken together. For example, income taxes are progressive in the United Kingdom, rising to a maximum marginal rate of 40 per cent. The overall tax system is also progressive, but much less so than one would guess from studying 105 only the income tax rates. This is because much revenue is raised by indirect taxes, which are much less progressive than income taxes. Exercises: 1.

Can you think of government programmes that would have effects on all three goals of equity, efficiency, and growth? Select those programmes that have desirable effects on some and undesirable effects on others of these three goals. (Assume that your equity criterion is to have a less unequal distribution of income.) Discuss the trade-offs involved in these policy conflicts. 3. Discuss the relative efficiency and equity effects of two programmes designed to assist certain needy groups. One programme provides coupons that reduce the purchase price of groceries by 50 per cent. (The shop returns the coupons to the governmentand gets back the discount that it gave to the coupon106 holder.) The other programme gives a money income supplement that has the same value as the food coupons. 4.

When you think of «business» what picture do you have in your mind Xerox, American Airlines, American Telephone and Telegraph? If so, you are on the right track. But business in America is more than the large corporations with which we are all familiar. Businesses come in all shapes and sizes. Businesses are either goods-producing or service-producing firms. Goodsproducing firms, such as mining, construction, and manufacturing firms, produce tangible products or goods -commodities that have a physical presense. Service-producing firms provide services - activities that benefit consumers or other businesses. Transportation firms, insurance companies, beauty shops, and repair shops are all examples of service businesses. But, regardless of whether a business produces a good or provides a service, the common ingredient is profit. Profit is the difference between a business's total revenues or sales receipts and the total of its production costs, operating expenses, and taxes. In a bread bakery example the bakery has to pay for its raw materials (flour, butter or shortening, yeast, salt), equipment (mixers, ovens, wrapping machines), employees, and the energy it uses. When the bakery sells the bread to the supermarket, it charges more than the cost of making the bread. That extra part of the selling price is profit. Why do businesses want profit? Profit is the ultimate goal of business. It is the measure of success for the businessperson and the reward for taking a chance. Each person who operates a business is risking money. The baker does not know that people will buy the bread when it is produced: but money is invested in the business on the possibility that people will buy. The baker is taking a chance, a risk. Were there no profits, it would not be worthwhile for the baker to risk the money. 114 Questions: 1. 2. 3. 4. 5. What is business? In what shapes do business come in? Why do businesses want profit? How do you understand the category of «profit»? Do people who operate businesses risk money? If there were no profits do people risk money in business? Text 2. BUSINESS AND PRIVATE ENTERPRISE In the private enterprise system businesses are owned by private individuals, not by public institutions like the government. Private enterprise is based on four principles or rights: the right to private property, freedom of choice, profits, and competition. The right to private property. In the private enterprise system individuals have the right to buy, own, use, and sell property as they see fit. This right of ownership includes land, buildings, equipment, and intangible property such as inventions. The right of freedom of choice. The private enterprise system also provides the right of freedom of choice. This freedom of choice applies to the individual's right to decide what type of work to do, where to work, and how and where money is to be spent. The right to profit. In the private enterprise system, the person who takes the chance in starting the business by investing is guaranteed the right to all profits. This right is what attracts people to begin businesses, and it is the ultimate goal of business. Not all entrepreneurs are successful, but the opportunity is there to start a business and reap the rewards. The right to compete. Under the private enterprise system people have the freedom to compete with others. Competition, along with profit, is the cornerstone of the private enterprise system. Competition makes for better products and more responsiveness to consumer needs. The private enterprise system, as do all economic systems, requires resources for its business to produce goods and services. The resources used to provide goods and services are the factors of production: land, labour, capital, and entrepreneurship. One of the major decisions an entrepreneur must make is to determine which legal form of business ownership to use in creating a business venture. There are three basic forms of business ownership: 1) sole proprietorship; 2) partnership; 3) corporation. Questions: 1. What principles or rights is private enterprise system based on? 2. Who owns the resourses necessary for production and business under the private 115 3. 4. 5. 6. enterprise system? What does the right to property mean in capitalism? How do you understand the right of freedom of choice under the private enterprise system? What is the cornerstone of the private enterprise system? What basic forms of business ownership do you know? Text 3. SOURCES OF FINANCING It is essential to start with sufficient capital. A company with inadequate financing is like a rowboat with a hole in the bottom: given enough time, it is bound to sink. Some small-business owners dream and save for so long that they reach the end of their patience and open the business come hell or high water. Rather than, start a company on a shoestring, it is best either to wait until there is enough capital to ensure success or to begin on a smaller scale than originally planned. Both accountants and trade associations can help potential business owners decide if they have enough capital to make a sound beginning. Personal savings. Personal savings is the source of financing used most often. Many observers advise small-business owners to avoid excessive borrowing. Firms that start off under the heavy weight of creditors' claims may take years to struggle out of debt, while their owners have to put up with the nervous questions and suggestions of the creditors. Still, under the right circumstances, a firm can profit impressively using the leverage of borrowed money. Thus the question of how much debt a firm should carry in relation to the owner's investment has no simple answer. Manufacturer financing of equipment. Manufacturers (and sometimes distributors) of equipment and fixtures may be willing to finance purchases made by financially sound customers or help them to arrange financing through a commercial bank. Even if they do not get involved directly, the supportive phone call from a well-established manufacturer to a bank lending officer might make it considerably easier for a customer firm to get a loan. Commercial banks. A commercial bank may make a term loan that the small business can pay off within several years. In addition, commercial banks give qualified small businesses a line of credit or a revolving credit agreement. Naturally the business owner will have to provide financial statements listing personal and company assets and debts. Unfortunately banks are often reluctant to lend money to companies that have only been operating for a few years unless the loan also is secured by the Small Business Administration /SBA/. The Small Business Administration. The steps in the SBA lending process are: 1. Describe the kind of business to be started. 2. List the owner's experience and management capabilities. 3. Estimate the amount the owner is prepared to invest and the amount he or 116 4. 5. 6. 7. 8. 9. she will need to borrow. Prepare a personal financial statement listing the owner's assets and debts. Develop pro forma statements of the business's sales, expenses and profits for the first 2 years. List the owner's collateral (security) for the loan, at current market value. Ask a commercial bank for a letter stating the amount of the loan the owner requested, the interested rate, the payment terms, and the reason for rejecting the application. If the bank agrees to be involved in the SBA's guarantee or participation plans (in which the bank joins with the SBA to make the loan), the banker will contact the SBA to negotiate the terms. If the bank declines to be involved, contact the SBA for a direct loan. Questions: 1. 2. 3. 4. May a company do business without sufficient capital? What are the main sources of financing business? Are personal savings used in starting a business? On what terms do commercial banks usually lend money to small-owners? Are they reliable partners in business? 5. What kind of financial help can the Small Business Administration provide to small-owners and on what terms? Text 4. BUSINESS TERMINATION There are several ways in which a company may be terminated (dissolved): its registration may be cancelled, it may be removed from the register if it has simply ceased to function as a company; or, it may be liquidated, or wound up. This means that its resources will be used to pay creditors in an established order priority. It is likely that the reason the company is being wound up is that it is bankrupt - that is, it cannot pay all its debts. This means that creditors may only get a proportion of what they are owed. As mentioned above, shareholders may be liable for up to the value of shares they hold but have not, yet paid for. Sometimes liquidation is voluntary, at the insistence of most of the shareholders, and sometimes it is ordered by the court. Setting up, running, and winding down a company are not the only legal matters businessmen have to deal with. At some stage, most of them employ the services of lawyers for advice on how to minimize their tax liabilities and to make sure their business does not exceed noise or pollution regulations. Company directors, partners and sole traders alike have to consider the legal implications of making contracts to buy and supply goods and services, and the torts they may face if a product injures a consumer. Questions: 1. In what ways may companies be terminated? 117 2. A company may be liquidated or wound up. How are its resources used in this case? Whom do they pass to? 3. For which value of shares are shareholders liable in case their company has gone bankrupt? 4. May companies be liquidated at the insistence of the shareholders or not? If they may, then in what cases? 5. What kind of legal matters do businessmen usually deal with in their business daily activities? Do they employ the services of lawyers? In what cases? Read the texts and give a short summery of the texts. Text 5. INFLATION AND BUSINESS Inflation can adversely affect business in a number of ways: 1. Accounting and financial problems. Significant rates of inflation can cause accounting and financial problems for businesses. They may experience difficulty in valuing assets and stocks, for example. Such problems can waste valuable management time and make forecasting, comparisons and financial control more onerous. 2. Falling sales. Many businesses may experience falling sales during inflationary periods for two broad reasons. Firstly, it may be that saving rises in a time of inflation. We would expect people to spend more of their money when prices are rising to avoid holding an asset (cash), which is falling in value. However, during the mid-1970s, when industrialized nations were experiencing high inflation rates, savings as a proportion of income rose! It is not easy to identify the reason for this, but some economists suggest that people like to hold a relatively high proportion of their assets in a form which can tie quickly converted into cash when the future is uncertain. Whatever the reason, if people save more they spend less and businesses suffer falling sales. The economic model predicts that if savings rose the level of activity in the economy would fall. Clearly, if this happened we would expect businesses to experience difficulty in maintaining their levels of sales. Businesses may be hit by a reduction in sales during a time of inflation for a second reason. As inflation progresses, it is likely tliat workers' money wages (that is, wages unadjusted for inflation,) will be increased broadly in line with inflation. This may well take a worker into a higher tax bracket and result in a higher percentage of his or her wages being taken as tax. This process, known as fiscal drag, will cause workers to have less money available to spend on firms' goods and services. The poverty trap has a similar impact. As money wages rise, the poor may find that they no longer qualify for state benefits to supplement their incomes and at the same time they begin to pay income tax on their earnings. Again, this leaves less disposable income to spend on the output of firms. Finally, it may be that the wages of many groups are not index-linked and so they rise less quickly 118 than the rate of inflation, causing a reduction in spending power and demand for goods and services. Once again, the economic model can be used to predict that increases in the level of taxation will increase withdrawals, lowering the level of economic activity and depressing firms' sales. Not all businesses will suffer equally from declining demand in an inflationary period. Those selling essential items, such as food, may be little affected whilst others supplying less essential goods and services, such as foreign holidays, may be hard hit. 3. High interest rates. Inflation is often accompanied by high interest rates. High interest rates tend to discourage investment by businesses as they increase the cost of borrowing funds. Thus, investment may fall. Businesses may also be dissuaded from undertaking investment programmes because of a lack of confidence in the future stability and prosperity of the economy. This fall in investment may be worsened by foreign investment being reduced as they also lose some confidence in the economy's future. Such a decline in the level of investment can lead to businesses having to retain obsolete, inefficient and expensive means of production and cause a loss of international competitiveness. Finally, a fall in investment can lower the level of economic activity, causing lower sales, output and so on. Thus, to some extent, businesses can influence the economic environment in which they operate. 4. Higher costs. During a bout of inflation firms will face higher costs for the resources they need to carry on their business. They will have to pay higher wages to their employees to compensate them for rising prices. Supplies of raw materials and fuel will become more expensive as will rents and rates. The inevitable reaction to this is that the firm has to raise its own prices. This will lead to further demands for higher wages as is called the wage-price spiral. Such costpush inflation may make the goods and services produced by that enterprise internationally less competitive in terms of price. An economy whose relative or comparative rate of inflation is high may find that it is unable to compete in home or foreign markets because its products are expensive. The economic model tells us that a situation of declining exports and increasing imports will lower the level of activity in the economy with all the consequent side-effects. Text 6. THE MAIN FORMS OF BUSINESS ORGANIZATION Business is the production, distribution, and sale of goods and services for the benefit of the buyer and the profit of the seller. In the modern world the control of production is largely in the hands of individual business people or entrepreneurs, who organize and direct industry for gaining profits. The main forms of business organization are described below. Individual Proprietorship (Sole Trader or Sole Proprietor). This is the simplest way of starting a business. You are self-employed and fully responsible for all the aspects of the management of your business. 119 In this form of organization the owner is in sole charge of the business and is responsible for its success or failure. Any line of business is open to an owner. Although this form of small business has its advantages, it has certain drawbacks. In the first place the single owner is seldom able to invest as much capital as can be secured by a partnership or a corporation. If single owners are able to invest large amounts of capital, they run great risk of losing it all because they are personally liable for all the debts of their businesses. This is called unlimited liability. Partnership. Two or more people starting a business together can set up a partnership. All partners are responsible for the debts of the partnership and profits and losses are shared between them. The agreement to form an association of this nature is called a partnership contract and may include general policies, distribution of profits, fiscal responsibilities, and a specific length of time during which the partnership is in effect. Public and private companies. A company is usually formed for the purpose of conducting business that is separate from its owners, the shareholders. The main difference is between public and private companies. Private companies cannot sell shares to or raise money from the general public. Public companies can sell their shares to the general public (which they usually do through a stock exchange). A company continues to exist despite changes in (or deaths among) its owners. A company can hold assets; it can sue, and it can be sued. The profits are distributed to the members as dividends on their shareholding. Losses are borne by the company. The day-to-day management of the company is carried out by a board of directors. Private limited companies are often local family businesses and are common in the building, retailing and clothing industries. A private company can be formed with a minimum of two people becoming its shareholders. They must appoint a director and a company secretary. If the company goes out of business, the responsibility of each shareholder is limited to the amount that they have contributed; they have limited liability. Such a company has Ltd (Limited) after its name. Many large businesses in the UK are Public Limited Companies (PLC), which means that the public can buy and sell their shares on the stock exchange. Marks & Spencer, British Telecom and the National Westminster Bank are the examples of public limited companies. In the US, businesses take the same basic forms. American companies have abbreviations Inc and Corp. Other types of companies are: 1) Associated company, which is a company over which another company has substantial influence; for example it owns between 20 per cent and 50 per cent of its shares. 2) Holding company, a company that owns another company or other companies and which is sometimes referred to as the parent company (most public companies 120 operate through a number of companies controlled by the group's holding company); 3) Subsidiary company, a company controlled by a holding company, usually because the holding company owns (or indirectly owns through another subsidiary) more than 50 per cent of the subsidary company's shares. The Corporation. As business became more competitive, new and more complex corporate combinations appear. Single ownerships and the partnerships have finance weaknesses and that is the reason why the corporation came into existence. The major simple forms of integration are the following: • A vertical integration characterizes companies that engage in the different steps in manufacturing or marketing a product. • A horizontal combination brings under one control companies engaged in the sale of the same or similar products. • A complementary combination takes place when companies, selling allied but not competitive products, combine. • A conglomerate combination involves firms in widely diverse industries, such as a motor company owning a food manufacturer or book publisher. • Of great economic importance are multinational corporations. Such companies maintain extensive business activities and large-scale production facilities throughout the world, and their revenues sometimes exceed the total revenues of some countries in which they operate. International business is a dynamic activity which changes, adapts and responds according to the conditions. Apart from conventional trade it takes various forms such as franchising, buy-back transactions, turnkey projects, transactions in patents, licences, know-how, services, various joint ventures, joint banks, mixed commissions and many other forms. Franchising. Franchising is a form of business in which a product or service may be provided by people or firms who have obtained a licence from the originators or owners of that product or service. A franchise agreement is drawn up in which the rights of the two parties are set down. The parties to the agreement are: a) the franchisor — usually the person or firm who develops a new product or service under licence b) the franchisee — the person or firm who buys the license granting the right to provide the product or service. The franchisor will have tried the product out by piloting it for a reasonable trading period before selling it to potential franchisees. The franchisee is provided with a total package for marketing the product, including tho product's name and logo, any patented processes, accounting procedures, marketing strategy and training services. The franchisee has to raise capital to pay the franchise fee, find suitable premises, equip them according to the franchisor's house-style, buy or lease equipment, and market the product to the standard specified by the franchisor. The franchisee is not employed by the franchising company, but has to establish and operate his own business. The fees are to be paid to the franchisor 121 throughout the term of the franchise, usually as a royalty, for example a fixed percentage (typically 10%) of weekly takings. Advantages. Franchising provides the opportunity of developing business without having large capital sums. For the franchisee it: a) enables people to go into business with limited risk and outlay, b) insures that the product or service has been thoroughly tested and marketed before the franchise has been approved, c) provides a well-known brand name and image, and large-scale advertising backup, d) requires less capital than other forms of business start-up, e) provides continuing back-up support and advice during the period of the franchise agreement.

WHAT IS MARKETING? Marketing is the performance of business activities that direct the flow of goods and services from producer to consumer or user. Simply to produce a product is not enough: the product must be transported, stored, priced, advertised, and sold before the satisfaction of human needs and wants is accomplished. Marketing activities range from the initial conception and design of the product to its ultimate sale, and account for about half the cost of the product. Marketing is the whole process of having the right product, at the right time, in the right place, calling attention to it and thereby bringing a mutual benefit to customer and vendor. Customers benefit by having what they want, when and where they want it. Vendors benefit by making a profit. The greater the benefits customers perceive, the more frequently they will trade with the businesses that provide them. You are engaging in marketing when you: Design or develop a product or service. Transport and store goods. Provide a variety of choice. Buy in large volumes and sell them by item. Install, service, repair, instruct. Update and improve. Marketing is the Four Ps: The product, the place, the price, and the promotion. But most of all, marketing is research: finding out who the customers are and what they need. Successful vendors never forget that benefit lies in the customer's perception, not in the vendor's. Marketing is asking the question, «Who will buy my product or service?» Although many critics claim that the cost of marketing is too high, an analysis of the marketing functions does not bear these criticisms out. Rather than think of the cost of marketing, one should consider the value added through marketing. Marketing becomes too costly only when its cost exceeds the value it adds. Questions: 1. 2. 3. 4. 5. What is marketing? What benefits do vendors and customers have from marketing? What are the main tasks of marketing? How wide do marketing activities range? Is the cost of marketing high? What do you think of it. Give a short summery of the text Text 2. MARKETING The word marketing has a broad meaning including both the market research concerning the goods which are going to be produced and the advertisement 128 already existing ones. If you want to introduce a new product and find a ready market for it you should know the market situation in detail. When there is a business boom people have generally more money on luxury items. When there is a slack and unemployment tends to increase one can sell products, which are not necessary for life, even in big quantities, but only if their price is as low as possible. This is only one arbitrary example of the way to consider the general market situation. Particular market situation deals more with the tastes and fashions of the present and near future. Fashion and consumers tastes and needs are constantly changing. So market research-should promptly find out such changes. This was the case with the increase in price of fuel oil when wood and coal for heaters became popular again. Those who were prepared for this change in the market did a great business. Thus customers' wishes should be foreseen and satisfied. Of course market research may not disregard any existing or probable competition. To sell a similar product in the market succesfully a manufacturer should make sure whether the demand is sufficient. Then he should either improve the quality or offer lower prices. Advertisement is a very important branch of marketing which develops with the development of mass media. It is a well-known fact that more and more money is spent on advertisement every year. Apparently it pays off and it is not always true that the consumer has to pay more for the goods he buys because of the commercials being so expensive. Actually if an ad gives rise to an exceedingly high sales rate of a product its production cost can even become lower. Besides newspapers and magazines would be much more expensive but for advertisement covering most of the publishing costs. The most efficient ad is the so called directly addressed ad. This kind of advertisement addresses some certain sector of the society, taking into account the values the people of this particular group appreciate. It is essential to choose the right media, the most popular source of information among this group of people. An effective commercial should fulfill requirements. In America this ru|e is called «AIDA» which means that a good ad creates Attention, Interest and Desire and leads to Action. One of the oldest means of advertisement is a fair. Fairs date back to early middle ages and have proved to be really efficient ever since. At that time sovereigns could give their towns a privilege of conducting an event like that. Every year over 60 fairs and exhibitions take place in the Federal Republic of Germany. The biggest and most well known one is organized in Hannover, where more than 4500 home and foreign companies have the chance to display their products. 129 Read the texts and answer the questions Text 3. MARKETING FUNCTIONS Marketing adds value to the product by the specific functions it performs. These are: Marketing information. Market information flows throughout the marketing process, from consumer to retailer, from retailer to wholesaler, from wholesaler to manufacturer. Producers are made aware of coming trends because marketers inform them of changes in consumer wants, supply and demand, and new market developments. B u y i n g . Before stocking shelves, a retailer must first determine not only what to buy but how much, which models or styles, in what sizes and colors. Buying is a fine art that may involve forecasting or predicting fashion trends six months or even a year in advance. S e l l i n g . Marketers must not only know what goods are available but must also inform potential buyers of where those goods can be bought and how much they cost. Selling may also involve helping consumers discover their own unconscious needs and wants. T r a n s p o r t i n g . In order to have value, goods must first be transported from the place they are produced to the point where they are needed. S t o r i n g . Because marketers often maintain extensive inventories, the consumer desire to buy is satisfied without waiting. C r e d i t - g r a n t i n g . Most manufacturers grant credit to wholesalers who, in turn, grant credit to retailers, who grant credit to the consumer. This is an important function because it enables those involved in the marketing channel to operate with less capital. R i s k - t a k i n g . Marketers assume risk in granting credit and in storing inventories (e.g. spoilage, theft, obsolescence). P r i c i n g . Pricing involves the art of determining which price is best. Is demand elastic or inelastic? Will consumers buy proportionately more of a good at a lower price? Will the reverse hold true? S e r v i c i n g . Many retailers provide credit, delivery, shop-at-home services, catalog sales, layaways, etc. Standardizing and g r a d i n g . Standardizing involves the maintenance of uniform size and quality standards throughout an industry. In buying a lightbulb, for example, few of us have any doubts as to whether that bulb will fit or how much light it will furnish. Grading is also an important marketing function, particularly in the processing of agricultural products. Farm commodities, such as eggs, milk, wheat, etc., are assigned grades attesting their quality and uniformity. Questions: 1. Why does marketing add value to the product? 2. What are the essential functions of marketing? 130 3. What kind of information do marketers inform producers of? Why do producers need this information? 4. What can you say about such functions of marketing as credit-granting and pricing? How big is their role in today's trade? 5. Why are standardizing and grading important in marketing activities? Text 4. THE MARKETING CONCEPT This concept involves two ideas: (1) Th e ma r k e t i n g d e p a r t me n t b e c o me s t h e ma i n ma n a g e me n t f o r c e i n a c o mp a n y . The company recognizes that essentially every important decision facing the company is in reality a marketing decision. Because the firm has the technological ability to produce almost anything, most companies realize that production is no longer a problem. The problem today is one of determining whether or not the corporation can market the products it is capable of producing. (2) Th e c o mp a n y b e c o me s c o mp l e t e l y c o n s u me r - o r i e n t e d . Most of today's new products come about as a result of extensive marketing research. With the consumer foremost in the mind of the company, long before production begins, the firm must first answer such questions as: ▪ Is there a need or want for the product that we are capable of producing? ▪ What characteristics or (attributes should that product possess? ▪ How can we differentiate our product from similar and competing products? ▪ What styles, colors, models, sizes, etc., should be produced? ▪ What channels of distribution are best? ▪ What price policy will most maximize profits? ▪ What types of people or market segments will the product most appeal to? Questions: 1. What ideas does the marketing concept involve? 2. Why does the marketing department become the main management force in a company? 3. What makes the company be completely consumer oriented? 4. Which questions must the firm fist answer before it begins to produce goods or services? 5. Does your own firm follow this concept or does it have another one? Text 5.MARKETING RESEARCH Marketing research is defined as the systematic gathering, recording, and analyzing of marketing data. The five basic steps involved in conducting marketing research are: (1) defining the problem, (2) collecting secondary data, (3) collecting primary data, (4) compiling and collating the data, and (5) analyzing and interpreting the results. Defining the problem. Before attempting any type of research it is important that the firm come up with a clear and concise statement of the problem. This may 131 well be the most important step in conducting any form of research because if the wrong problem is defined, the wrong problem will be solved. Collecting secondary data. Secondary data is information easily obtained through examination of company records or through library research. In general, a firm should always try to solve its problem using secondary data rather than collecting primary or first-hand data: secondary information is much faster and cheaper. Two major problems do exist, however, when using secondary data: the data may be out of date, and there is the possibility of bias. Collecting primary data. The three basic methods for collecting primary data are: O b s e r v a t i o n me t h o d . Some marketing problems can be solved simply through observation. E x p e r i me n t a l me t h o d . This is the basic approach used in the sciences. For example, most firms introducing a new product first test-market the product in a limited location before attempting national distribution. S u r v e y me t h o d . This method simply involves questioning people. It can be accomplished either through telephone interviews, personal interviews, or mailed questionnaires. Compiling and collating the data. The data is organized (collected manually or with use of electronic data processing equipment) so that it may be studied. Interpreting the findings. The final step in marketing research involves using the data after it has been analyzed. Interpretation of the findings is extremely important because it generally exerts great influence on management decisions relating to the original problem. Questions: 1. How can marketing research be defined? What are the basic steps involved in conducting it? 2. The first step of marketing research is defining the problem. What does it mean? 3. Collecting data is one of the most important steps in marketing research. How can firms obtain the necessary information? 4. What must you do after collecting secondary and primary data? 5. Which is the final step in marketing research? What does it involve? Is it of much importance or not? Give a short summery of the texts. Text 6. CREAT A MEDICAL PRACTICE MARKETING PLAN Creating a marketing plan for a medical practice is no different from creating a marketing plan for any other business. The purpose of a marketing plan is to serve as a road map or blueprint for the future. Here is an analogy: if you are planning to go on a trip, you prepare by buying maps and guidebooks. Similarly, in 132 order to manage the future of your practice, you need a well-designed plan that includes future goals and a series of practical steps designed to reach those goals. A marketing plan is an analytic process designed to change amorphous concepts into clearly defined steps that lead to a desired result. A marketing plan has several basic elements: 1) Situation review 2) External environment assessment – Internal environment assessment 3) SWOT analysis 4) Objectives 5) Target audiences 6) Strategies 7) Tactics 8) Measurement 9) Budgeting Situation Review The situation review is like a diagnosis of your practice. It comprises an evaluation of your current situation and an overview of your current market. You begin by researching the internal and external environment. You will need to identify national trends, the competitive environment in your community, potential patients' needs, and current patients' perceptions and needs. You will use this information to identify opportunities and create the objectives of your marketing plan. Below are the important questions to ask and data to gather. External Environment Assessment Begin with the big picture. What are the national trends in insurance, particularly managed care? Is there under- or oversaturation of physicians in your specialty? What are the effects of changing referral pathways on your specialty or type of practice? Which new technologies are affecting your patients' care? Some key questions in this era of managed care are – What managed care plans are predominant in your community? How many enrollees are in each plan? How much growth is anticipated in managed care plans? Are you a provider on the panels of these plans? (If you are not participating in the right plans in your area, you are automatically eliminating a potential large patient base before you even begin to think about other aspects of marketing.) You can acquire information on the number of enrollees in managed care plans (both HMOs and PPOs) from insurance companies or state medical societies. To assess your competition, find out how many physicians are in your community (both physicians in your specialty and potential referrers). Ask two vital questions: What is the competition doing? What are they not doing? When you uncover something they are not doing, you have identified an opportunity. What are the demographics of your community? What are the current numbers and the projected growth over the next five years? Which groups are growing in number? Children, middle-aged women, the elderly? Your Chamber of Commerce probably can provide these data. What are the current medical trends in your community? For example, is there a trend toward preventive care, increased use of ambulatory care, shorter hospital stays, or increased home health care? Survey potential patients to learn whether they are interested in fitness, nutrition, sports medicine, or preventive medicine strategies. Are their main concern hours of operation? If so, do they require Saturday and evening hours? 133 Internal Environmental Assessment How many additional patients could your practice handle currently? What is your capacity? (Nothing would be worse than to attract so many patients that you could not offer them quality service.) What is your practice's market share in the community? Determine total projected number of visits based on the population (you can obtain the appropriate rate to use from your specialty's national organization), then determine what percentage of those visits are yours. Is your practice computerized so that you can generate accurate demographic data on your patients? In what ZIP codes do most of your patients live? Should you consider placing a satellite office in one or more of these? Can your computers provide a breakdown of patients in managed care plans and in Medicare and fee-for-service segments? (If you do not have a system that allows you to collect and analyze these data, be sure your next computer system does offer this capability.) Regularly survey your current patients to assess their perceptions and attitudes. The tool can be as simple as a postcard with five or six questions that are easy for an office staff member to tally on a weekly basis. For example, ask patients whether they were seen within 15 minutes of their arrival. Ask if their calls are returned promptly. Leave space for subjective opinions and suggestions for improved service. If you are a small practice, for example, you may learn that personalized service is a strong desire – and that is something you could provide better than a large organization or a multispecialty group practice. Not long ago, a group of pediatricians I know joined a large HMO. When one of their old patients called, she reached an answering service that said, "Please leave us your name and chart number and within one hour a doctor or nurse will call you back." In one hour a nurse did call back – a complete stranger who did not know how to handle the specific situation. The patient waited another two hours at home while the nurse gave the message to the doctor. Then a different nurse called back and answered the question. This patient never did get to speak to the doctor herself, and she still feels certain uneasiness about the lack of personal attention. That kind of story is a clue to a marketing opportunity. If I were a pediatrician in that city, I would position myself as someone who is available. "When you call our practice, you’ll hear a familiar voice, ready to help you, and you'll be able to speak directly to the doctor when you need to." A situation analysis is an opportunity to think about your strengths and capabilities and then base your marketing efforts upon the strengths you have to offer. Ask your colleagues and referral base to tell you about their perceptions about your practice. Ask for their suggestions – and be prepared to implement them if you do! That will demonstrate that you are concerned and that you are listening. SWOT Analysis Using the data acquired in your external and internal analyses, you should be able to write a quick list of your practice’s strengths, weaknesses, opportunities, and threats (SWOT). Using your SWOT list, you should be able to pinpoint 134 marketing objectives or desired outcomes for your marketing plan. Sample SWOT items are given below. Strengths • We have 40 percent managed care patients compared with the community's average of only 25 percent. • We are an obstetric practice delivering patients in a major tertiary hospital, with all the benefits of high technology and capable of caring for high-risk pregnancies. Weaknesses • We are a family practice with only three providers, so we are at capacity and already have waiting lists, particularly because we act as gatekeepers in so many managed care plans. • Our obstetric patients are increasingly moving out to the suburbs and say they would prefer to see a physician closer to home, even though they like the idea of delivering at a large downtown hospital. Opportunities • Recruit additional physicians, nurse practitioners, or physicians’ assistants to handle the growing patient load. • Open satellite offices in the suburbs in which the highest percentage of our patients live (as revealed by a ZIP code analysis). Threats • Younger, upscale families are moving into our community and insist on using a pediatrician instead of a family practice physician because their perception is that a family physician is not as well-trained to handle children. • More and more patients are seeking both obstetricians and hospitals closer to home. By systematically listing all SWOT factors, you have constructed the foundation of your marketing plan. You are basing your plans on research and analysis, not on speculative ideas and gut feelings. Shooting from the hip will not work in 1996 or beyond. You have to get the data and devise a systematic, informed research plan. Objectives You need to think in terms of different types of objectives – marketing and communications objectives as well as personal goals. It is not enough to just set very general goals. Do not just say, "I want to build up my practice." You need to set specific goals that include numerical values and usually a deadline. A typical marketing objective might be something like this: "We want to increase revenues by 15 percent and new patients by 10 percent within the next 12 months." Or you might say, "By the end of next year we'd like our clientele to be 40 percent managed care, 30 percent Medicare, and 30 percent fee-for-service." A primary care practice might set a goal of increasing pediatric patients by 10 percent, since pediatric patients are likely to stay with a practice for a long time. In any case, you need to think carefully about your goals and objectives and write them down in clear, specific language, because they provide the targets 135 against which you measure your success. Remember, you cannot hit a target you cannot see. Target Audiences First, analyze all the potential patients and customers in the community you want to influence, including individuals and organizations. Begin with your own employees. Are they satisfied? Do they feel good at the end of the day? Do they feel they are valued and appreciated and have opportunities to grow? Or are they stressed out? Do you have a high turnover rate? Any marketing plan must start at the top, but the employees must buy into it for it to succeed, since they will play an important role in implementing it. If the employees do not buy into it, all your effort will be wasted. Your current patients, both active and inactive, are another vitally important target audience. You have to look at ways to continue to satisfy your active patients as well as ways to reactivate patients who have drifted away. Look at a wide range of important target audiences: new patients, potential patients, referring physicians, insurance companies and providers, and managed care plans. In addition, think of all the target audiences that are sources of referrals: pharmacists and pharmaceutical representatives, attorneys, social workers, clergy, civic and community organizations. How much of an impact have you had in the media, print and electronic? Strategies A strategy is a general plan or method for accomplishing a goal. Suppose, for example, that your target audience is your employees and your goals include ensuring that your employees experience pride and high morale, are loyal to the practice, have low turnover, are very productive, and have opportunities for personal growth. Your strategies might include trying to improve employer-employee communication, instituting a reward system, arranging for continuing education, and demonstrating recognition of exemplary performance. If your target audience consists of current active patients and your goals include maintaining your relationship with these patients, promoting patient satisfaction and word-of-mouth marketing, and making these patients ambassadors of your practice, your strategies might include improving communication, service, and access to your practice and regularly surveying attitudes and perceptions. (Table 39-1 shows possible goals, key messages, and strategies for six target audiences.) Tactics Tactics are the specific, detailed methods used to carry out a strategy and achieve a goal. For example, if your goal is to provide outstanding service, you might want to perform a patient service cycle and evaluate the way the patients are treated from the time they enter the practice until they leave. Based on this evaluation, you would develop a specific tactical plan for improved service. Your tactics might include weekend, evening, and early morning hours if that is what your patients want. Develop effective scheduling so there is no waiting time. Provide patients a “no paperwork” service. Offer optional installment billing for elective surgery patients. Provide educational materials. 136 If your goal is to provide more services, you might want to set up a patient network where patients can talk to other patients about their experiences. You might consider offering the services of a nutritionist. Exercises: 1. Complete the sentences by using the words from the texts: A) Marketing is the Four Ps: ..

A number of different terms are often used instead of the term «manager», including «director», «administrator» and «president». The term «manager» is used more frequently in profit-making organizations, while the others are used more 140 widely in government and non-profit organizations such as universities, hospitals and social work agencies. So, who do we call a «manager»? In its broad meaning the term «managers» applies to the people who are responsible for making and carrying out decisions within a certain system. A personnel manager directly supervises people in an organization. Financial manager is a person who is responsible for finance. Sales manager is responsible for selling of goods. Almost everything a manager does involves decision-making. When a problem exists a manager has to make a decision to solve it. In decision-making there is always some uncertainty and risk. Management is a variety of specific activities. Management is a function of planning, organizing, coordinating, directing and controlling. Any managerial system, at any managerial level, is characterized in terms of these general functions. Managing is a responsible and hard job. There is a lot to be done and relatively little time to do it. In all types of organizations managerial efficiency depends on manager's direct personal relationships, hard work on a variety of activities and preference for active tasks. The characteristics of management often vary according to national culture, which can determine how managers are trained, how they lead people and how they approach their jobs. The amount of responsibility of any individual in a company depends on the position that he or she occupies in its hierarchy. Managers, for example, are responsible for leading the people directly under them, who are called subordinates. To do this successfully, they must use their authority, which is the right to take decisions and give orders. Managers often delegate authority. This means that employees at lower levels in the company hierarchy can use their initiative, that is make decisions without asking their manager. Questions: 1. What is manager's role in an organization? 2. What concrete activities a production manager (financial manager, personnel manager, marketing manager) is responsible for? 3. What is the difference between sales management and marketing management? 4. What means to delegate authority? Text 2. MARKETING MANAGEMENT Management is a function of planning, organizing, coordinating, directing and controlling. Any managerial system, at any managerial level, is characterized in terms of these general functions. Management is a variety of specific activities. Marketing management refers to a broad concept covering organization of production and sales of products, which is based on consumer requirements research. All companies try to look beyond their present situation and develop a long-term strategy to meet changing 141 conditions in their industry. Marketing management, therefore, consists of evaluating market opportunities, selecting markets, developing market strategies, planning marketing tactics and controlling marketing results. Strategic planning includes defining the company's long-term objectives as well as specific objectives, such as sales volume, market share, profitability and innovation, and deciding on financial, material and other resources necessary to achieve those objectives. In problems of market selection and product planning one of the key concepts is that of the Product Life Cycle. That products pass through various stages between life and death (introduction — growth — maturity — decline) is hard to deny. Equally accepted is the understanding that a company should have a mix of products with representation in each of these stages. Companies can make far more effective marketing decisions if they take time to find out where each of their products stands in its life cycle. However, the concept of the product life cycle seems frequently forgotten in marketing planning, which leads to wrong decision-making. This may well be seen in the following story. A supplier of some light industrial equipment felt that the decline in the sales of his major product was due to the fact that it was not receiving the sales support it deserved. In order to give extra sales support to this problem case, a special advertising campaign was run. This required cutting into marketing budgets of several promising products that were still in their «young» growth phase. In fact, the major product has long since passed the zenith of its potential sales, and no amount of additional sales support could have extended its growth. This became quite clear in the end-of-year sales results which showed no improvement. The promising products, however, went into gradual sales decline. In short, management has failed to consider each product's position in its life cycle. Questions: 1. What is strategic planning? 2. Why is the Product Life Cycle considered one of the key concepts in marketing? 3. What is marketing management? Give a short summery of the texts. Text 3. MANAGEMENT AND CONTROL OF COMPANIES The simplest form of management is the partnership. In Anglo-American common-law and European civil-law countries, every partner is entitled to take part in the management of the firm's business, unless he is a limited partner; however, a partnership agreement may provide that an ordinary partner shall riot participate in management, in which case he is a dormant partner but is still personally liable for the debts and obligations incurred by the other managing partners. The management structure of companies or corporations is more complex. The simplest is that envisaged by English, Belgian, Italian, and Scandinavian law, 142 by which the shareholders of the company periodically elect a board of directors who collectively manage the company's affairs and reach decisions by a majority vote but also have the right to delegate any of their powers, or even the whole management of the company's business, to one or more of their number. Under this regime it is common for a managing director (directeur general, direttore generale) to be appointed, often with one or more assistant managing directors, and for the board of directors to authorize them to enter into all transactions needed for carrying on the company's business, subject only to the general supervision of the board and to its approval of particularly important measures, such as issuing shares or bonds or borrowing. The U.S. system is a development of this basic pattern. By the laws of most states it is obligatory for the board of directors elected periodically by the shareholders to appoint certain executive officers, such as the president, vice president, treasurer, and secretary. The latter two have no management powers and fulfill the administrative functions that in an English company are the concern of its secretary; but the president and in his absence the vice president have by law or by delegation from the board of directors the same full powers of day-today management as are exercised in practice by an English managing director. The most complex management structures are those provided for public companies under German and French law. The management of private companies under these systems is confided to one or more managers (gerants, Geschaftsfuhrer) who have the same powers as managing directors. In the case of public companies, however, German law imposes a two-tier structure, the lower tier consisting of a supervisory committee (Aufsichtsrat) whose members are elected periodically by the shareholders and the employees of the company in the proportion of two-thirds shareholder representatives and one-third employee representatives (except in the case of mining and steel companies where shareholders and employees are equally represented) and the upper tier consisting of a management board (Vorstand) comprising one or more persons appointed by the supervisory committee but not from its own number. The affairs of the company are managed by the management board, subject to the supervision of the supervisory committee, to which it must report periodically and which can at any time require information or explanations. The supervisory committee is forbidden to undertake the management of the company itself, but the company's constitution may require its approval for particular transactions, such as borrowing or the establishment of branches overseas, and by law it is the supervisory committee that fixes the remuneration of the managers and has power to dismiss them. The French management structure for public companies offers two alternatives. Unless the company's constitution otherwise provides, the shareholders periodically elect a board of directors (conseil d'admi-nistration), which «is vested with the widest powers to act on behalf of the company» but which is also required to elect a president from its members who «undertakes on his own responsibility the general management of the company,» so that in fact the board of directors' functions are reduced to supervising him. The similarity to the German pattern is obvious, and French legislation carries this further by openly permitting public companies to establish a supervisory committee (conseil de 143 surveillance) and a management board (directoire) like the German equivalents as an alternative to the board of directors-president structure. Dutch and Italian public companies tend to follow the German pattern of management, although it is not expressly sanctioned by the law of those countries. The Dutch commissarissen and the Italian sindaci, appointed by the shareholders, have taken over the task of supervising the directors and reporting on the wisdom and efficiency of their management to the shareholders. Text 4. SEPARATION OF OWNERSHIP AND CONTROL The investing public is a major source of funds for new or expanding operations. As companies have grown, their need for funds has grown, with the consequence that legal ownership of companies has become widely dispersed. For example, in large American corporations, shareholders may run into the hundreds of thousands and even more. Although large blocks of shares may be held by wealthy individuals or institutions, the total amount of stock in these companies is so large that even a very wealthy person is not likely to own more than a small fraction of it. The chief effect of this stock dispersion has been to give effective control of the companies to their salaried managers. Although each company holds an annual meeting open to all stockholders, who may vote on company policy, these gatherings, in fact, tend to ratify ongoing policy. Even if sharp questions are asked, the presiding officers almost invariably hold enough proxies to override outside proposals. The only real recourse for dissatisfied shareholders is to sell their stock and invest in firms whose policies are more to their liking. (If enough shareholders do this, of course, the price of the stock will fall quite markedly, perhaps impelling changes in management personnel or company policy.) Occasionally, there are «proxy battles,» when attempts are made to persuade a majority of shareholders to vote against a firm's managers (or to secure representation of a minority bloc on the board), but such struggles seldom involve the largest companies. It is in the managers' interest to keep the stockholders happy, for, if the company's shares are regarded as a good buy, then it is easy to raise capital through a new stock issue. Thus, if a company is performing well in terms of sales and earnings, its executives will have a relatively free hand. If a company gets into trouble, its usual course is to agree to be merged into another incorporated company or to borrow money. In the latter case, the lending institution may insist on a new chief executive of its own choosing. If a company undergoes bankruptcy and receivership, the court may appoint someone to head the operation. But managerial autonomy is the rule. The salaried executives typically have the discretion and authority to decide what products and services they will put on the market, where they will locate plants and offices, how they will deal with employees, and whether and in what directions they will expand their spheres of operation. The markets that corporations serve reflect the great variety of humanity and human wants; accordingly, firms that serve different markets exhibit great differences in technology, structure, beliefs, and practice. Because the essence of 144 competition and innovation lies in differentiation and change, corporations are in general under degrees of competitive pressure to modify or change their existing offerings and to introduce new products or services. Similarly, as markets decline or become less profitable, they are under pressure to invent or discover new wants and markets. Resistance to this pressure for change and variety is among the benefits derived from regulated manufacturing, from standardization of machines and tools, and from labour specialization. Every firm has to arrive at a mode of balancing change and stability, a conflict often expressed in distinctions drawn between capital and revenue and long-and short-term operations and strategy. Many corporations have achieved relatively stable product-market relationships, providing further opportunity for growth within particular markets and expansion into new areas. Such relative market control endows corporate executives and officers with considerable discretion over resources and, in turn, with considerable corporate powers. In theory these men and women are hired to manage someone else's property; in practice, however, many management officers have come increasingly to regard the stockholders as simply one of several constituencies to which they must report at periodic intervals through the year. Text 5. EXECUTIVE MANAGEMENT Managerial decision-making. The guidelines governing management decisions cannot be reduced to a simple formula. Traditionally, economists have assumed that the goal of a business enterprise was to maximize its profits. There are, however, problems of interpretation with this simple assertion. First, over time the notion of «profit» is itself unclear in operational terms. Today's profits can be increased at the expense of profits years away, by cutting maintenance, deferring investment, and exploiting staff. Second, there are questions over whether expenditure on offices, cars, staff expenses, and other trappings of status reduces shareholders' wealth or whether these are part of necessary performance incentives for executives. Some proponents of such expenditures believe that they serve to enhance contacts, breed confidence, improve the flow of information, and stimulate business. Third, if management asserts primacy of profits, this may in itself provide negative signals to employees about systems of corporate values. Where long-term success requires goodwill, commitment, and cooperation, focus on short-term profit may alienate or drive away those very employees upon whom long-term success depends. Generally speaking, most companies turn over only about half of their earnings to stockholders as dividends. They plow the rest of their profits back into the operation. A major motivation of executives is to expand their operations faster than those of their competitors. The important point, however, is that without profit over the long term no firm can survive. For growing firms in competitive markets a major indicator of executive competence is the ability to augment company earnings by increasing sales or productivity or by achieving savings in other ways. This principle distinguishes the 145 field of business from other fields. A drug company makes Pharmaceuticals and may be interested in improving health, but it exists, first and foremost, to make profits. If it found that it could make more money by manufacturing frozen orange juice, it might choose to do so. Text 6. THE MODERN EXECUTIVE Much has been written about business executives as «organization men». According to this view, typical company managers no longer display the individualism of earlier generations of entrepreneurs. They seek protection in committeemade decisions and tailor their personalities to please their superiors; they aim to be good «team» members, adopting the firm's values as their own. The view is commonly held that there are companies-and entire industries-that have discouraged innovative ideas. The real question now is whether or not companies will develop policies to encourage autonomy and entrepreneurship among managers. In Japan, where the employees of large corporations tend to remain with the same employer throughout their working lives, the corporations recruit young men upon their graduation from universities and train them as company cadets. Those among the cadets who demonstrate ability and a personality compatible with the organization are later selected as managers. Because of the seniority system, many are well past middle age before they achieve high status. There are signs that the system is weakening, however, as efforts are more often made to lift promising young men out of low-echelon positions. Criticism of the traditional method has been stimulated by the example of some of the newer corporations and of those owned by foreign capital. The few men in the Japanese business world who have emerged as personalities are either founders of corporations, managers of family enterprises, or small businessmen. They share a strong inclination to make their own decisions and to minimize the role of directors and boards. Exercises: 1.

The XX-th century, along with the second millennium, is coming to its end. The XXI-st century along with the third millennium is entering into its rights. Mankind is approching a new and very important chronological boundary. On the threshold of the third millennium it is full of hopes. Never before the world had such unlimited possibilities for further developing civilization. But it is also a world that is overburdened by dangers and contradictions. This makes our time probably the most troubling period of history. How should countries and nations with different views, ideologies, and policies shape their relations in such a world? Will they make the simple laws of morality and justice, which ought to govern relations among private individuals, into the supreme laws also in relations among nations. Russia is prepared to do this. The differencies between social systems, countries and nations are both numerous and fundamental. But the need to solve urgent universal problems should compel them to cooperate, to awaken the instinct and forces of mankind's self-preservation. What is required is constructive cooperation of states on a global 148 scale so that, terrestrial civilization may survive. But the world cannot be saved of the way of thinking and actions built up over the centuries on the acceptability and permissibility of wars and armed conflicts are not shed once and for all, resolutely and irrevocably. Therefore Russia tries to base its relations with other countries on the following principles: First. The character of present-day weapons leaves no country any hope of safeguarding itself exclusively by military-technological means. The task of ensuring security is seen increasingly as a political problem. Second. Security can only be universal and mutual. Third. There is an objective need for ail states of the world to live in peace with each other and to cooperate on a basis of equality and mutual benefit. They must learn to live in a civilized manner, without ignoring their existing differencies, in other words, under conditions of civil international relations and cooperation. Confrontation between them must occur only and exclusively in forms of peaceful competition and peaceful rivalry. Questions: 1. What chronological boundary are we all approching? What hopes do you tie with this event? 2. What kind of problems does mankind face on the threshold of the third millennium? 3. Scientistis ensure us that global matters (problems) can be solved now. What do you think of it? 4. Is our world overburdened by dangers and contradictions? If so, which are they? 5. Are there in our days possibilities for further developing civilisation? 6. Do you think that our time is the most troubling period of history? 7. On which principles should countries and nations with different ideologies base their relations? 8. Is there an objective need for all states of the world to live in peace and decide their differencies by peaceful means? 9. Do you think that peaceful coexistence is possible between different civilisations? 10. How is the task of ensuring security seen now? Text 2. THE MAIN DIRECTIONS OF RUSSIAN FOREIGN POLICY Russia has never threatened anyone, nor does it threaten anyone now. We lay no territorial claims against any country in the world, nor do we intend to deprive anyone of his natural or any other wealth. The fundamental direction of Russia's foreign activity is the struggle against the nuclear threat, against the arms race, for the preservation and strengthening of universal peace. Its ultimate goal is to provide the Russian people with the possibility of working and living in conditions of lasting peace and freedom. 149 The world historic experience convincingly says that the genuinely reliable security of one nation cannot be ensured at the expense of the other nation. Security can be reliable only if it is equal, if no state lays claim to exclusiveness. This is clearly understood in today's Russia which attaches considerable significance to its relations with the nuclear powers, primarely with the United States, and seeks to promote cooperation with them on a basis of equality and mutual benefit. Russia also pays especial attention to maintaining its traditionally good relations with neighbouring coutries, that entered the Soviet Union not long ago and are forming now a new community - the Community of Independent States. The strengthening of close and friendly relations with socialist China and democratic India is in the centre of Russia's policy too. Russia is in favour of constructive quests for ways of defusing conflict situations in the Middle and Near East, Central America, Asia and the other regions. Crises and conflicts are fertile soil for international terrorisminciples, Russia rejects terrorism and is prepared to cooperate with all the countries in order to uproot it. One of the main directions of the Russian international activity is the European one. The future of Europe lies, in our view, in peaceful cooperation among the states of that continent. While preserving the experience that has already been accumulated, it is important to move further, to a more stable and dependable security through a radical reduction of nuclear and conventional weapons and close cooperation in deciding all other global problems. This is what we should think about, this is where the power of human intellect and hands should be directed. This should be done without delay, for time is pressing as never before. Questions: 1.

It has maped unprecedented plans for restructuring the economy and the mechanism of managing it. Important for this stage is the development of new forms of foreign economic activity, such as direct access for enterprises and organisations to the world market, joint ventures, broader direct links, industrial and technological cooperation, and the like. That is why Russia wants international economic relations to be normalized and economic development made stable and predictable. The situation in the world economy remains complicated and contradictory. On the one hand the international division of labour continues to develop, enhancing economic interdependance of states. On the other hand, the aggravation of many economic, trade and political problems hampers the development of international economic cooperation. Practice shows that spontaneous development of international economic relations compounds and increases problems and contradictions. Falling oil prices, the deteriorating debt problem, rapid changes in the correlation of leading currencies, and sharp fluctuations at the world stock exchanges prove the world economy and national economies defenceless before upheavals. This harms economic interests of states, breeding uncertainty in tomorrow. Would the world trade be overburdened with protectionism? Would an economic crisis in a major power trigger a chain reaction with unpredictable consequences? That is why Russia suggests establishing a broad dialogue on economic issues of all interested parties and finding solutions to problems on the basis of concord, which would guarantee that these solutions are objective and fair. At this stage of world development, economic cooperation, like political or militarystrategic cooperation, should be reformed on the basis of a new thinking, which is the ability to realistically assess this dynamic world. The Russian concept of economic security, on inalienable part of the comprehensive system of international security, is designed to establish on all-round international cooperation free from confrontation. Until we restore order in this sphere of international relations on principles acceptable to all, humanity would continue to be threatened by catastrophic crises and upheavals, which would inevitably affect all nations, however strong economically. Questions: 1. What kind of economic plans did Russia map ten years ago? At what are they directed? 2. Is the development of new forms of foreign activity important now? Why? 3. Which new forms of foreign economic activity do you know? 4. Does Russia want international economic relations to be normalized and made stable and predictable? 5. Why does the situation in the world economy remain complicated and contradictory? 151 6. Which problems in the world economy are, in your opinion, the sharpest and the most difficult to be solved? 7. On what basis does Russia suggest to solve sharp economic problems of the world? 8. What is the Russian concept of economic security designed to? 9. What can you say about today's correlation of Russian and foreign leading currencies? Is it fair? Exercises: 1.

INTERNATIONAL TRAD Sales and purchases of goods and services that take place across international boundaries are referred to as international trade. For example, the British buy BMWs made in Germany, Germans take holidays in Italy, Italians buy spices from Tanzania, Belgians import oil from Kuwait, Egyptians buy Japanese cameras, the Japanese depend heavily on American soybeans as a source of food, and the Taiwanese make many electronic goods whose parts are manufactured throughout Southeast Asia. There is substantial evidence to show that international trade and economic growth are positively linked. An economy that engages in international trade is an open economy. One that does not is a closed economy. A situation in which a country does no foreign trade is called autarky. The advantages realized as a result of trade are called the gains from trade. Although politicians often regard foreign trade as different from domestic trade, economists from Adam Smith on have argued that the causes and consequences of international trade are simply an extension of the principles governing domestic trade. Let us start by thinking about trade between individuals. Without trade, each person would have to be self-sufficient; each would have to produce all the food, clothing, shelter, medical services, entertainment, and luxuries that she consumed. 153 A world of individual self-sufficiency would be a world with extremely low living standards. Trade between individuals allows people to specialize in those activities they can do relatively well and to buy from others the goods and services they themselves cannot easily produce. A good doctor who is a bad carpenter can provide medical services not only for her own family, but also for an excellent carpenter who lacks the training or the ability to practise medicine. Thus, trade and specialization are intimately connected. Without trade, everyone must be selfsufficient. With trade, everyone can specialize in what she does well and satisfy other needs by trading. The same principles apply to regions. Without interregional trade, each region would be forced to be self-sufficient. With trade, each region can specialize in producing goods or services for which it has some natural or acquired advantage. Plains regions can specialize in growing grain, mountain regions can specialize in mining and forest products, and regions with abundant manpower can specialize in manufacturing. Cool regions can produce dairy products, wool, and crops that thrive in temperate climates, and hot regions can grow such tropical crops as rice, cotton, bananas, sugar, and coffee. Places with lots of sunshine and sandy beaches can specialize in the tourist trade. The living standards of the inhabitants of all regions will be higher when each region specializes in products in which it has some natural or acquired advantage and obtains other products by trade than when all regions seek to be self-sufficient. The same principle applies to nations. Nations, like regions or persons, can gain from specialization. Almost all countries produce more of some goods than their residents wish to consume. At the same time, they consume more than they produce of some other goods. International trade is necessary to achieve the gains that international specialization makes possible. Trade allows each individual, region, or nation to concentrate on producing those goods and services that it produces relatively efficiently, while trading to obtain goods and services that it would produce less efficiently than others. Specialization and trade go hand in hand, because there is no motivation to achieve the gains from specialization without being able to trade the goods produced for the different goods desired. The term 'gains from trade' encompasses the results of both. There are three main sources of gains from trade. The first is those differences between regions of the world in climate and resource endowment that lead to advantages in producing certain goods and disadvantages in producing others. These gains would occur even if each country's costs of production were unchanged by the existence of trade. The second source is the reduction in each country's costs of production resulting from the greater production that specialization brings. The third is the international competition, which usually promotes more rapid technological change and economic growth than would occur if domestic firms produced solely for a protected home market. 154 Text 2. GAINS FROM SPECIALIZATION WITH GIVEN COSTS In order to focus on differences in countries' conditions of production, suppose that each country's average costs of production are constant. We will use an example below involving only two countries and two products, but the general principles apply as well to the real-world case of many countries and many products. One region is said to have an absolute advantage over another in the production of good X when an equal quantity of resources can produce more X in the first region than in the second. These gains from specialization make possible the gains from trade. If consumers in both countries are to get the goods they desire in the required proportions, each must export some of the commodity in which it specializes and import commodities in which other countries are specialized. When each country has an absolute advantage over others in a product, the gains from trade are obvious. But what if one country can produce all commodities more efficiently than other countries? In essence this was the question that English economist David Ricardo (1772-1823) posed 200 years ago. His answer underlies the theory of comparative advantage, which is still accepted by economists today as a valid statement of the potential gains from trade. The gains from specialization and trade depend on the pattern of comparative rather than absolute advantage. Let us assume that there are two economies, the United States and the European Union. Both produce the same two goods, wheat and cloth, but the opportunity costs of producing these two products differ between countries. For the moment we assume that this opportunity cost is constant in each country at all combinations of outputs. The gains from trade arise from differing opportunity costs in the two countries. The slope of the production possibility boundary indicates the opportunity costs, and the existence of different opportunity costs implies comparative advantages and disadvantages that can lead to gains from trade. Conclusions about the gains from trade arising from international differences in opportunity costs can now be summarized. 1. Country A has a comparative advantage over country B in producing a product when the opportunity cost (in terms of some other product) of production in country A is lower. This implies, however, that it has a comparative disadvantage in the other product. 2. Opportunity costs depend on the relative costs of producing two products, not on absolute costs. 3. When opportunity costs are the same in all countries, there is no comparative advantage and there is no possibility of gains from specialization and trade. 4. When opportunity costs differ in any two countries, and both countries are producing both products, it is always possible to increase production of both products by a suitable reallocation of resources within each country. 155 Text 3. GAINS FROM SPECIALIZATION WITH VARIABL COSTS If costs vary with the level of output, or as experience is acquired via specialization, additional sources of gain are possible. Real production costs, measured in terms of resources used, often fall as the scale of output increases. The larger the scale of operations, the more efficiently large-scale machinery can be used and the more efficient the division of labour that is possible. Smaller countries such as Switzerland, Belgium, and Israel, whose domestic markets are not large enough to exploit economies of scale, would find it prohibitively expensive to become self-sufficient by producing a little bit of everything at very great cost. Trade allows smaller countries to specialize and produce a few products at high enough levels of output to reap the available economies of scale. One of the important lessons learned from patterns of world trade since the Second World War results from imperfect competition and product differentiation. Virtually all of today's manufactured consumer goods are produced in multiple differentiated product lines. In some industries many firms produce this range; in others only a few firms produce the entire product range. In both cases firms are not price-takers, and they do not exhaust all available economies of scale, as a perfectly competitive firm would do. This means that an increase in the size of the market, even in an economy as large as the USA or the EU, may allow the exploitation of some previously unexploited scale economies in individual product lines. These possibilities were first dramatically illustrated when the European Common Market (now called the European Union, the EU) was set up in the late 1950s. Economists had expected that specialization would occur according to the classical theory of comparative advantage, with one country specializing in, say, cars, another in refrigerators, another in fashion clothes, another in shoes, and so on. This is not the way it worked out. Instead, much of the vast growth of trade was in intra-industry trade. Today one can buy French, English, Italian, and German fashion goods, cars, shoes, appliances, and a host of other goods in the shops of London, Paris, Berlin, and Rome. Ships loaded with Swedish furniture bound for London pass ships loaded with English furniture bound for Stockholm; and so on. What free European trade did was to allow a proliferation of differentiated products, with different countries each specializing in differentiated sub-product lines. Consumers have shown by their expenditures that they value this enormous increase in the range of choice between differentiated products. As Asian countries have expanded into European and American markets with textiles, cars, and electronic goods, European and American manufacturers have increasingly specialized their production, and they now export textiles, cars, and electronic equipment to Japan even while importing similar but differentiated products from Japan. 156 The discussion so far has assumed that costs vary only with the level of output. They may also vary with the experience accumulated in producing a good over time. Text 4. TRADE AS A SOURCE OF TECHNOLOGICAL CHANG AND ECONOMIC GROWTH When countries protect their home markets with high tariffs, they reduce the amount of international competition faced by their domestic firms. This is particularly important when the countries are small so that there is room for only a few, or possibly even just one, domestic firm to serve the local market. In these circumstances, International trade can increase competitive pressures that face domestic firms. This in turn may lead to more product and process innovation than occurred under protection. Also, because firms throughout the world are innovating in both product and production processes, an open trading regime allows consumers to benefit from the many technological changes that occur in other countries as well as locally. Text 5. TERMS OF TRADE A rise in the price of imported goods, with the price of exports unchanged, indicates a fall in the terms of trade; it will now take more exports to buy the same quantity of imports. Similarly, a rise in the price of exported goods, with the price of imports unchanged, indicates a rise in terms of trade; it will now take fewer exports to buy the same quantity of imports. Thus, the ratio of these prices measures the amount of imports that can be obtained per unit of goods exported. Because actual international trade involves many countries and many products, a country's terms of trade are computed as an index number: Terms of trade = Index of export prices Index of import prices X 100% A rise in the index is referred to as a favourable change in a country's terms of trade. A favourable change means that more can be imported per unit of goods exported than previously. For example, if the export price index rises from 100 to 120 while the import price index rises from 100 to 110, the terms of trade index rises from 100 to 109. At the new terms of trade, a unit of exports will buy 9 per cent more imports than at the old terms. A decrease in the index of the terms of trade, called an unfavourable change, means that the country can import less in return for any given amount of exports or, equival-ently, that it must export more to pay for any given amount of imports. These are the real exchange rate and competitiveness. They also are indexes of the relative prices of domestic and foreign goods. However, both competitiveness and the real exchange rate normally relate to the prices of 157 domestic production relative to foreign production, while terms of trade apply just to the subset of outputs that are imported and exported. Text 6. THE CASE FOR FREE TRADE Government policy towards international trade is known as commercial policy. Complete freedom from interference with trade is known as a free trade policy. Any departure from free trade designed to give some protection to domestic industries from foreign competition is called protectionism. Today debates over commercial policy are as heated as they were two hundred years ago when the theory of gains from trade that we presented above was still being worked out. Should a country permit the free flow of international trade, or should it seek to protect its local producers from foreign competition? Such protection may be achieved either by tariffs, which are taxes designed to raise the price of foreign goods, or by non-tariff barriers, which are devices other than tariffs that are designed to reduce the flow of imports. Examples of the latter include quotas and customs procedures deliberately made more cumbersome than is necessary. The case for free trade is based on the analysis presented above. We saw that for any given set of costs, whenever opportunity costs differ among countries, specialization and trade will raise world living standards. Free trade allows all countries to specialize in producing products in which they have a comparative advantage. Free trade allows the maximization of world production, thus making it possible for each consumer in the world to consume more goods than she could without free trade. This does not necessarily mean that everyone will be better off with free trade than without it. Protectionism could allow some people to obtain a larger share of a smaller world output so that they would benefit even though the average person would lose. If we ask whether it is possible for free trade to improve everyone's living standards, the answer is 'yes'. But if we ask whether free trade does in fact always do so, the answer is 'not necessarily'. There is abundant evidence that significant differences in opportunity costs exist and that large gains are realized from international trade because of these differences. What needs explanation is the fact that trade is not wholly free. Why do tariffs and non-tariff barriers to trade continue to exist two centuries after Adam Smith and David Ricardo stated the case for free trade? Is there a valid case for protectionism? Text 7. THE CASE FOR PROTECTIONISM Two kinds of argument for protection are commonly offered. The first concerns national objectives other than total income; the second concerns the desire to increase one country's national income, possibly at the expense of world national income. 158 Objectives other than maximizing national income It is possible to accept the proposition that national income is higher with free trade, and yet rationally to oppose free trade, because of a concern with policy objectives other than that of maximizing income. Comparative advantage might dictate that a country should specialize in producing a narrow range of products. The government might decide, however, that there are distinct social advantages in encouraging a more diverse economy. Citizens would be given a wider range of occupations, and the social and psychological advantages of diversification would more than compensate for a reduction in living standards to, say, 5 per cent below what they could be with complete specialization of production according to comparative advantage. For a very small country, specializing in the production of only a few products—though dictated by comparative advantage—may involve risks that the country does not wish to take. One such risk is that technological advances may render its major product obsolete. Everyone understands this risk, but there is debate over what governments can do about it. The pro-tariff argument is that the government can encourage a more diversified economy by protecting industries that otherwise could not compete. Opponents argue among other things that governments, being naturally influenced by political motives, are in the final analysis poor judges of which industries can be protected in order to produce diversification at a reasonable cost. Another non-economic reason for protectionism concerns national defence. It used to be argued, for example, that the United Kingdom needed an experienced merchant navy in case of war, and that this industry should be fostered by protectionist policies even though it was less efficient than the foreign competition. The same argument is sometimes made for the aircraft industry. Agriculture has also been protected for strategic reasons in the past—we would need to feed ourselves if trade were disrupted by war. The United States does not allow foreign ships to transport cargo between its domestic ports on the grounds that a strong merchant navy, which would not exist without protection, is needed for times of war. Although free trade will maximize per capita GDP over the whole economy, some specific groups may have higher incomes under protection than under free trade. An obvious example is a firm or industry that is given monopoly power when tariffs are used to restrict foreign competition. If a small group of firms, and possibly their employees, find their incomes increased by, say, 25 per cent when they get tariff protection, they may not be concerned that everyone else's incomes fall by, say, 2 per cent. They get a much larger share of a slightly smaller total income and end up better off. If they gain from the tariff, they will lose from free trade. Tariffs tend to raise the relative income of a group of people who are in short supply domestically and to lower the relative income of a group of people who are in plentiful supply domestically. Free trade does the opposite. 159 Other things being equal, most people prefer more income to less. Economists cannot say that it is irrational for a society to sacrifice some income in order to achieve other goals. Economists can, however, do three things when faced with such reasons for adopting protectionist measures. First, they can ask if the proposed measures really do achieve the ends suggested. Second, they can calculate the cost of the measures in terms of lowered living standards. Third, they can see if there are alternative means of achieving the stated goals at lower cost in terms of lost output. Maximizing national income. Here we consider five important arguments for the use of tariffs when the objective is to make national income as large as possible. The oldest valid argument for protectionism as a means of raising living standards concerns economies of scale. It is usually called the infant industry argument. This comes in a static and a dynamic form. The static form assumes that world technology is given and constant. If an industry has large economies of scale, costs will be high when the industry is small but will fall as the industry grows. In such industries the country first in the field has a tremendous advantage. A newly developing country may find that in the early stages of development its industries are unable to compete with established foreign rivals. A trade restriction may protect these industries from foreign competition while they grow. When they are large enough, they will be able to produce as cheaply as foreign rivals and then will be able to compete without protection. The dynamic form emphasizes that technology is constantly changing endogenously and that those countries who are at the frontier of technological advance have an enormous advantage of experience and acquired ability in inventing and innovating over those who seek to industrialize later on. To develop these abilities, so goes the argument, a country needs to protect its domestic industries during the early stages of development. The object is not to move along a given falling long-run cost curve. Instead, it is to develop industries that will have cost curves that fall, over time, as fast as similar cost curves are falling in the advanced countries owing to invention and innovation. To prevent the new industries from becoming stagnant under the protection that shields them from foreign competition, protection must, it is argued, be contingent on achieving success in foreign markets within a stated period of time. Once they have developed the skills needed to hold their own in the intense international competition associated with new technologies, the protection can be removed. The advocates of this argument point out that virtually all the economically advanced countries developed their early industries under tariff protection. This was true of Germany and France (and to some extent also of the early English industries in the industrial revolution, which were helped by the prohibition of imports of Indian cotton goods), the United States, Canada, Australia, and New Zealand, as well as the most successful of the Asian economies, e.g. Taiwan, South Korea, and Singapore. 160 Those who support such polices argue that the assumption of fixed technology that is implicit in the major arguments for completely free trade is misleading in a world in which most competition is in terms of the technological change. They also point out that the argument does not deny the importance of trade: it just holds that, to take part in globalized trade as a fully developed country, early protection may be needed—for reasons found both in the theory of endogenous technological change and in the evidence of what most developed countries actually did in the early stages of their development. In so far as there is any validity in this argument, it provides a possible qualification to the proposition that free trade maximizes world income. If some limited protection actually raises the level of world innovation in new products and processes, world income may be higher with some protection than with pure free trade. What this possibility shows is that, just like all propositions that follow from economic theory, the proposition that free trade maximizes world income is open to empirical testing. It is not something that can be shown to be necessarily true in the real world by virtue of theoretical propositions alone. The dynamic version of the infant industry argument is supported by the argument based on learning by doing. Skills and other things that help to create comparative advantages are not fixed for ever: they can be learned by producing the new products if enough time is allowed for the learning to take place. Learning by doing therefore suggests that the pattern of comparative advantage can be changed. If a country learns enough through producing products in which it currently is at a comparative disadvantage, it may gain in the long run by specializing in those products, and could develop a comparative advantage as the learning process lowers their costs. The successes of such newly industrializing countries (NICs) as Brazil, Hong Kong, South Korea, Singapore, and Taiwan are based largely on acquired skills. For example, nothing in Singapore or Taiwan in 1960—in terms of natural resources, capital, or skills—suggested that they would become major producers of state-of-the-art electronic products well before the end of the twentieth century. This type of experience provides evidence that comparative advantages can change, and that they can be developed by suitable government policies. Also, government policies created favourable business conditions and encouraged the development of specific industries that went on to develop comparative advantages—although the importance of such policies in contributing to these developments is subject to debate. Protecting a domestic industry from foreign competition may give its management time to learn to be efficient, and its labour force time to acquire the needed skills. If this is so, it may pay in the very long run to protect the industry against foreign competition while a dynamic comparative advantage is being developed. Some countries have succeeded in developing strong comparative advantages in targeted industries, but others have failed. One reason such policies sometimes fail is that protecting local industries from foreign competition may make the industries unadaptive and complacent. Another reason is the difficulty of identifying the 161 industries that will be able to succeed in the long run. All too often, the protected infant grows up to be a weakling requiring permanent tariff protection for its continued existence; or else the rate of learning is slower than for similar industries in countries that do not provide protection from the chill winds of international competition. In these instances the anticipated comparative advantage never materializes. Where such a 'picking of winners' has succeeded, it has almost always been the result of co-operation between government bodies and private sector firms, rather than civil servants picking and fostering potential winners on their own initiatives. Examples are Japan's auto industry, Taiwan's electronics industry, Singapore's software industry, and the software and semiconductor industries of the United States. A recent argument for tariffs or other trade restrictions is that they enable the creation of a strategic advantage in producing or marketing some new product that is expected to generate profits. To the extent that all lines of production earn normal profits, there is no reason to produce goods other than ones for which a country has a comparative advantage. Some goods, however, are produced in industries containing a few large firms where large-scale economies provide a natural barrier to further entry. Firms in these industries can earn extra-high profits over long periods of time. Where such industries are already well established, there is little chance that a new firm will replace one of the existing giants. The situation is, however, more fluid with new products. The first firm to develop and market a new product successfully may earn a substantial pure profit over all of its opportunity costs and become one of the few established firms in the industry. If protection of the domestic market can increase the chance that one of the protected domestic firms will become one of the established firms in the international market, the protection may pay off. Many of today's high-tech industries experience declining average total cost curves because of their large fixed costs of product development. For a new generation of civilian aircraft, silicon chips, computers, software, and Pharmaceuticals, a very high proportion of each producer's total costs goes on product development. These are the fixed costs of entering the market, and they must be incurred before a single unit of output can be sold. In such industries there may be room for only a few firms. The production of full-sized commercial jet aeroplanes provides an example of an industry that possesses many of these characteristics. The development costs of a new generation of jet aircraft have risen with each new generation. If the aircraft manufacturers are to recover these costs, each of them must have large sales. Thus, the number of firms that the market can support has diminished steadily, until today there is room in the world aircraft industry for only two or three firms producing a full range of commercial jets. The characteristics just described are sometimes used to provide arguments for subsidizing the development of such industries and/or protecting their home markets with a tariff. Suppose, for example, that there is room in the aircraft industry for only three major producers of the next round of passenger jets. If a government assists a domestic firm, this firm may become one of the three that 162 succeed, and the profits that are subsequently earned may more than repay the cost of the subsidy. Furthermore, another country's firm, which was not subsidized, may have been just as good as the three that succeeded; without the subsidy, however, that firm may lose out in the battle to establish itself as one of the three surviving firms in the market. This example is not unlike the story of the European Airbus. The European producers received many direct subsidies (and they charge that their main competitor, the Boeing 767, received many indirect ones). Whatever the merits of the argument, several things are clear: the civilian jet aircraft industry remains profitable; there is room for only two or three major producers; and one of these would not have been the European consortium had it not been for substantial government assistance. Generalizing from this and similar cases, some economists advocate that their governments should adopt strategic trade policies more broadly than they now do. This means, for high-tech industries, government protection of the home market and government subsidization (either openly or by more subtle back-door methods) of the product development stage. These economists say that if their country does not follow their advice it will lose out in industry after industry to the more aggressive Japanese and North American competition—a competition that is adept at combining private innovative activity with government assistance. Opponents argue that, once all countries try to be strategic, they will all waste vast sums trying to break into industries in which there is no room for most of them. Advocates of strategic trade policy reply that a country cannot afford to stand by while others play the strategic game. Advocates also argue that there are key industries that have major 'spillovers' into the rest of the economy. If a country wants to have a high living standard, it must, they argue, compete with the best. If a country lets its key industries migrate to other countries, many of its other industries will follow. The country then risks being reduced to the status of a less developed nation. Opponents argue that strategic trade policy is just the modern version of mercantilism, a policy of trying to enrich oneself at the expense of one's neighbours rather than looking for mutually beneficial gains from trade. They point to the rising world prosperity of the entire period following the Second World War, which has been built largely on a rising volume of relatively free international trade. There are real doubts that such prosperity could be maintained if the volume of trade were to shrink steadily because of growing trade barriers. Tariffs may be used to prevent foreign industries from gaining an advantage over domestic industries by use of predatory practices that will harm domestic industries and hence lower national income. Two common practices are subsidies paid by foreign governments to their exporters and price discrimination by foreign firms, which is called dumping when it is done across international borders. These practices are typically countered by levying tariffs known as countervailing and anti-dumping duties. Trade restrictions can be used to turn the terms of trade in favour of countries that produce, and export, a large fraction of the world's supply of some 163 product. They can also be used to turn the terms of trade in favour of countries that constitute a large fraction of the world demand for some product that they import. When the OPEC countries restricted their output of oil in the 1970s, they were able to drive up the price of oil relative to the prices of other traded goods. This turned the terms of trade in their favour; for every barrel of oil exported, they were able to obtain a larger quantity of imports. When the output of oil grew greatly in the mid1980s, the relative price of oil fell dramatically, and the terms of trade turned unfavourably for the oil-exploring companies. These are illustrations of how changes in the quantities of exports can affect the terms of trade. Now consider a country that provides a large fraction of the total demand for some product that it imports. By restricting its demand for that product through tariffs, it can force the price of that product down. This turns the terms of trade in its favour, because it can now get more units of imports per unit of exports. Both of these techniques lower world output. They can, however, make it possible for a small group of countries to gain because they acquire a sufficiently larger share of the smaller world output. However, if foreign countries retaliate by raising their tariffs, the ensuing tariff war can easily leave every country with a lowered income. In today's world a country's products must stand up to international competition if they are to survive. Over time this requires that they hold their own in competition for successful innovations. Protection that is high enough to confer a national monopoly reduces the incentive for firms to fight to hold their own internationally. If any one country adopts high tariffs unilaterally, its domestic industries may become less competitive. Secure in its home market because of the tariff wall, the protected industries may become less and less competitive in the international market. As the gap between domestic and foreign industries widens, any tariff wall will provide less and less protection. Eventually the domestic industries will succumb to the foreign competition. Although restrictive policies have sometimes been pursued following a rational assessment of the approximate cost, it is hard to avoid the conclusion that more often than not such policies are pursued for political objectives, or on fallacious economic grounds, with little appreciation of the actual costs involved. One major exception to this tendency is the postwar Japanese car industry. The Japanese government protected the local market against imports and prevented foreign firms from establishing production facilities in Japan. But fierce competition among the local Japanese firms led to the development of the methods of 'lean production' which, after 20 years of internal development, allowed Japanese firms to challenge foreign automobile industries and become world leaders in the industry. Text 8. METHODS OF PROTECTION Policies that directly raise prices The first type of protectionist policy directly raises the price of the imported product. A tariff, also often called an import duty, is the most common policy of 164 this type. Other such policies include any rules or regulations that fulfil three conditions: they are costly to comply with; they do not apply to competing, domestically produced products; and they are more than is required to meet any purpose other than restricting trade. The initial effect is to raise the domestic price of the imported product above its world price by the amount of the tariff. Imports fall, and as a result foreign producers sell less and so must transfer resources to other lines of production. The price received on domestically produced units rises, as does the quantity produced domestically. On both counts domestic producers earn more. However, the cost of producing the extra output at home exceeds the price at which it could be purchased on the world market. Thus, the benefit to domestic producers comes at the expense of domestic consumers. Indeed, domestic consumers lose on two counts: first, they consume less of the product because its price rises; and second, they pay a higher price for the amount that they do consume. This extra spending ends up in two places: the extra that is paid on all units produced at home goes to domestic producers (partly in the resource costs of extra production and partly in profit), and the extra that is paid on units still imported goes to the government as tariff revenue. Policies that directly lower quantities The second type of protectionist policy directly restricts the quantity of an imported product. Any implicit or explicit restriction on trade that does not involve a tariff is known as a non-tariff barrier. These can take various subtle forms, including quality standards that are complicated to interpret or customs forms that take weeks to get approved. But many non-tariff barriers are more obvious and easy to understand. A common example is the import quota, by which the importing country sets a maximum on the quantity of some product that may be imported each year. Increasingly popular in the recent past, however, has been the voluntary export restriction (VER), an agreement by an exporting country to limit the amount of a good that it sells to the importing country. The European Union and the United States have used VERs extensively, and the EU also makes frequent use of import quotas. Japan has been pressured into negotiating several VERs with the European Union and the United States in order to limit sales of some of the Japanese goods that have had the most success in international competition. Jot example, in 1983 the United States and Canada negotiated VERs whereby the Japanese government agreed to restrict total sales of Japanese cars to these two countries for three years. When the agreements ran out in 1986, the Japanese continued to restrain their car sales by unilateral voluntary action. In 2005 the EU negotiated a voluntary export restraint for exports of textiles from China. Text 9. GLOBAL COMMERCIAL POLICY We now consider the supranational influences on commercial policy in the world today. We start with the many international agreements that govern current commercial policies and then look in a little more detail at the European Union. 165 Before 1947 most countries were free to impose any tariffs on its imports. However, when one country increased its tariffs, the action often triggered retaliatory actions by its trading partners. The Great Depression of the 1930s saw a high-water mark of world protectionism, as each country sought to raise its employment by raising its tariffs. The end result was lowered efficiency, less trade—but no increase in employment. Since that time, much effort has been devoted to reducing tariff barriers, on both a multilateral and a regional basis. The GATT and the WTO One of the most notable achievements of the postwar era was the creation of the General Agreement on Tariffs and Trade (GATT). The principle of the GATT was that each member country agreed not to make unilateral tariff increases. This prevented the outbreak of tariff wars in which countries raise tariffs to protect particular domestic industries and to retaliate against other countries' tariff increases. Such wars usually harm all countries as mutually beneficial trade shrinks under the impact of escalating tariff barriers. There were eight 'rounds' of global trade talks under the GATT, beginning in 1948 and ending in 1993. The three most recently completed rounds of GATT agreements, the Kennedy round (completed 1967), the Tokyo round (completed 1979), and the Uruguay round (completed 1993), each reduced world tariffs substantially, the first two by about one-third each, and the last by about 40 per cent. The Uruguay round created a new body, the World Trade Organisation (WTO), which superseded the GATT in 1995. It also created a new legal structure for multilateral trading. Under this new structure all members have equal mutual rights and obligations. Until the WTO was formed, developing countries who were in the GATT enjoyed all the GATT rights but were exempt from most of its obligations to liberalize trade—obligations that applied only to the developed countries. However, all such special treatments were phased out over seven years starting in 1995. There is also a new dispute settlement mechanism with much more power to enforce rulings over non-tariff barriers than existed in the past. In its first eight years the WTO dealt with around 300 disputes; while the GATT only heard 300 in 47 years! In 1997 three strands of negotiation that had been left incomplete in the Uruguay round were completed, involving agreements to lower trade barriers in telecommunications, financial services, and information technology. These agreements were important because they greatly increased the amount of trade covered by WTO rules and dispute settlement procedures, they may lead to larger trade volume gains than the entire Uruguay round, and they complete most of the unfinished business from Uruguay, clearing the way for a new global trade round. This was started in 2001 at the Qatar capital, Doha, and hence known as the Doha round. This round was still continuing in 2006. By December 2005 the WTO had 149 member countries including China, with a further 30 or so, including Russia, at various stages of negotiation to join. 2 It is thus growing into a truly global forum for the regulation of government 166 involvement in world trade. There is further discussion of some of the issues surrounding the WTO in the second case study below. Indeed, while real GDP has grown ten-fold, world export volumes have grown twenty-eight-fold. It is hard to believe that this could have occurred without the liberalization of international trade brought about through successive rounds of tariff negotiation. Text 10. TYPES OF REGIONAL AGREEMENT Regional agreements seek to liberalize trade over a much smaller set of countries than WTO membership. Three standard forms of regional tradeliberalizing agreement are free trade areas, customs unions, and common markets. A free trade area (FTA) is the least comprehensive of the three. It allows for tariff-free trade among the member countries, but it leaves each member free to impose its own trade restrictions on imports from other countries. As a result, members must maintain customs points at their common borders to make sure that imports into the free trade area do not all enter through the member that is levying the lowest tariff on each item. They must also agree on rules of origin to establish when a good is made in a member country, and hence is able to pass duty-free across their borders, and when it is imported from outside the free trade area, and hence is liable to pay duties when it crosses borders within the free trade area. A customs union is a free trade area plus an agreement to establish common barriers to trade with the rest of the world. Because they have a common tariff against the outside world, the members need neither customs controls on goods moving among themselves nor rules of origin. A common market is a customs union that also has free movement of labour and capital among its members. An economic union takes things still further and creates an area that shares many other aspects of economic policy and harmonized legal structures, such as in the European Union today. TEXT 11. TRADE CREATION AND TRADE DIVERCION A major effect of regional trade liberalization is on resource reallocation. Economic theory divides these effects production into two categories. This occurs when producers in one member country find that they can undersell producers in another member country because the latter loses its tariff protection. For example, when the North American Free Trade Agreement (NAFTA) came into force, some Mexican firms found that they could undersell their US competitors in some product lines, while some US firms found that they could undersell their Mexican competitors in others, once tariffs were eliminated. As a result, specialization occurred and new international trade developed. This occurs when exporters in one member country replace foreign exporters as suppliers to another member country as a result of preferential tariff treatment. For example, US trade diversion occurs when Mexican firms find that they can 167 undersell competitors from the EU in the US market, not because they are the cheapest source free trade area has been formed, known as Mercosur. In 1994 an initiative was started to put in place a free trade area for the whole of the Americas. Negotiations started in 1998 and were scheduled to be concluded by January 2005; however, this deadline was not met. The new free trade area was planned to create the Free Trade Area of the Americas (FTAA), but at the time of writing (June 2006) there is considerable doubt as to whether this will come about in the foreseeable future. Text 12. COMMON MARKETS: THE EUROPEAN UNION By far the most successful common market, which is now referred to as a 'single market', is the European Union. Its origins go back to the period immediately following the Second World War in 1945. After the war there was a strong belief throughout Europe that the way to avoid future military conflict was to create a high level of economic integration between the existing nation-states. Later the motivation switched to creating a powerful economic bloc that could be competitive with Japan and the USA. In 1952, as a first step towards economic union, France, Belgium, West Germany, Italy, Luxembourg, and Holland formed the European Coal and Steel Community. This removed trade restrictions on coal, steel, and iron ore among these six countries. In 1957 the same six countries signed the Treaty of Rome. This created the European Economic Community (EEC), which later became the European Community (EC), and after 1993 the European Union (EU). In 1973 the United Kingdom, Denmark, and Ireland joined, and they were followed in 1981 by Greece and in 1986 by Spain and Portugal. Austria, Sweden, and Finland entered in 1995. The European Union welcomed ten new countries in 2004: Cyprus, the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, and Slovenia. Bulgaria and Romania followed in 2007. In the first two decades of its existence, the main economic achievements of the EEC were the elimination of internal tariff barriers and the establishment of common external tariffs (in other words, the establishment of a customs union), and the establishment of the Common Agricultural Policy (CAP), which guarantees farm prices by means of intervention and an import levy. There were other significant EEC policies, such as regional aid and protection of competition, but they did not have great economic impact to begin with. By the mid-1980s it was clear that the intended 'Common Market' had not been achieved. There remained many non-tariff barriers to trade and to the mobility of labour. These included quality standards, licensing requirements, and a lack of recognition of qualifications. In financial services there were explicit exchange controls and other regulatory restrictions on cross-border trade. In response, a new push to turn the customs union into a genuine common market began in 1985. The Single Market Act was signed in 1986. Its intention was to remove all remaining barriers to the creation of a fully integrated single market by the end of 168 1992. The Single Market Act did not in itself create the single market. Rather, it was a statement (or treaty) of intent which instituted a simplified administrative procedure whereby most of the single market legislation needed only 'weighted majority' support, rather than unanimity. The single market itself was to be created by a large number of Directives, which are drafted by the European Commission, the EU's civil service. These become Community law after they have been 'adopted' by the European Council (a committee of the heads of state or other ministers of member states). They then have to be ratified in the law of each member state. Once in force, they have precedence over the domestic laws of member states if there is a conflict. The elimination of non-tariff barriers has been approached on a product-byproduct basis. Only in this way could minimum quality standards be created that would permit cross-border trade without the threat of quality checks as a prerequisite to entry (a problem that plagues some branches of Canada-USA trade). This has required a complicated set of negotiations on quality standards, relating to everything from condoms to sausages and from toys to telecommunications. There is even a quality standard for the bacterial content of aqueous toys—transparent plastic souvenirs containing, perhaps, a model of Big Ben or the Eiffel Tower, which, when shaken, create a snow scene. All countries have such safety or quality standards for their products, and what has been happening is the harmonization of these standards, which is something that Canada and the United States have been trying to do since their Agreement was put into force in 1989. The Single Market Programme is an ongoing process, not a discrete jump. Some of the intended measures have been implemented, but many are still in the pipeline. The process will continue well into the twenty-first century. Perhaps the most significant achievements of the Single Market Programme to date have been in the area of trade in financial services. Although the Treaty of Rome called for free movement of capital as well as goods, this was ignored until the mid-1980s. Until recently, most member countries had exchange controls on capital movements until recently which prohibited residents of each country from investing in any other country. The Capital Liberalization Directive required all member states to abolish exchange controls by June 1990. Some member states, such as the UK and Germany, had already abolished controls. France and Italy, which had not, were forced to do so by the Directive. Spain, Portugal, Ireland, and Greece were given longer to comply. All except Greece fully abolished their controls by the end of 1992, and Greece abolished most of its controls by 1994. Once exchange controls were abolished, it could be argued that nothing else had to be done to create a single market in financial services. Certainly wholesale financial markets rapidly integrated with the global financial system, once they were free to do so. However, agreement was still needed on how to facilitate greater cross-border competition in retail financial markets. Each country in isolation had already created a domestic regulatory regime designed, in part, to protect the consumer. How was the EU to encourage competition but maintain a sensible regime of consumer protection? Financial services are particularly prone 169 to fraud, because the profit margin for a crook is 100 per cent—even a used car salesman has to show you a car, but the seller of an investment product offers only future promises! The European Union adopted a pragmatic approach based upon assuming the competence of existing regulators. Firms in each sector were to be authorized as 'fit and proper' by their home country regulator, and they would then be presumed to be fit and proper to trade in any member state. In effect, the home country gave a driving licence which then permitted an authorized company to 'drive' anywhere in the Union. This mutual recognition of regulators has been wrongly interpreted as permitting financial services firms to trade anywhere in the European Union on the basis of their home country's rules. A moment's thought will tell you why it has to be wrong. Imagine, for example, British drivers being permitted to drive on the left in France just because that is the law in Britain. It is just as disastrous to have banks in any one location trading under fifteen different legal structures. The single market in financial services is built on a dual set of principles: home country authorization, and host country conduct of business rules. This means that a firm can be authorized to trade throughout the Union by the home regulator, but the trade itself must obey the local laws in the country concerned. Allowing home countries to regulate entry and host countries to regulate performance is a simple application of the principle of national treatment that was developed in the context of the Uruguay round. It means that foreign firms get treated just the same as local firms. The Cecchini Report of 1989 estimated that the completion of the Single Market Programme may increase the GDP of the European Union by up to 6 per cent. However, a well known American economist, Richard Baldwin, has challenged that figure, suggesting that the gains could be at least twice as large (owing to economies of scale external to firms). And this is only the gain in one year. Similar gains will continue to flow in future years. Thus, while politically tortuous, the process of reducing trade barriers, even within groups of countries, is capable of creating considerable gains in economic efficiency. In 2000 a renewed agenda for economic progress in the European Union up to 2010 was adopted at a European Council meeting in Lisbon, Portugal (hence known as the Lisbon Agenda). It aims at making 'the EU the world's most dynamic and competitive economy' by 2010. Little progress towards this goal had been made by 2005 so it was relaunched: It is accepted that member states have not made the necessary progress on the Lisbon Agenda goals. There have been some advances on specific goals, for example the liberalisation of energy, telecoms and financial services sectors. But the headline objectives of boosting jobs by 20 million and ensuring annual growth of 3 per cent by 2010 a year will not be met. . . . European Commission President Jose Manuel Barroso said in February: 'Lisbon has been blown off course by a combination of economic conditions, international uncertainty, slow progress in the member states and a gradual loss of political focus.'Leaders are likely to address these problems by reducing the number of goals and focusing on boosting 170 jobs and growth. Instead of the current confusing myriad of progress indicators there will be one national action programme and implementation report for each country. (BBC website, March 2005) Text 13. THE FUTURE OF THE MULTILATERIAL TRADING SYSTEM At the end of the Second World War the United States took the lead in forming the GATT and in pressing for reductions in world tariffs through successive rounds of negotiations. Largely as a result of this US initiative, the world's tariff barriers have been greatly reduced, while the volume of world trade has risen steadily. The next few years will be critical for the future of the multilateral trading system, which has served the world so well since the end of the Second World War. The dangers are, first, a growth of regional trading blocs that will trade more with their own member countries and less with others, and second, the growth of state-managed trade. The 1920s and 1930s provide a cautionary tale. Arguments for major trade restrictions always have a superficial appeal and sometimes have real short-term payoffs. In the long term, however, a major worldwide escalation of tariffs would lower efficiency and incomes and restrict trade worldwide, while doing nothing to raise employment. Both economic theory and the evidence of history support this proposition. Although most agree that pressure should be put on countries that restrict trade, the above analysis suggests that these pressures are best applied using the multilateral institution, the WTO. Unilateral imposition of restrictions in response to the perceived restrictions in other countries can all too easily degenerate into a round of mutually escalating trade barriers. In the first few years of the twenty-first century, the United States has been more protectionist than at any other time during the last half of the previous century. New heavy anti-dumping duties on steel and softwood lumber and big new protectionist measures for the US agricultural industry are causing worrying ripples internationally. If the United States abandons the position it established over the last 60 years as the leader of the movement for trade liberalization, there is no obvious successor. The European Union, although it has achieved something close to free trade within the Union, has been equivocal on free trade with the rest of the world. Antidumping duties, voluntary export agreements, and other non-tariff barriers have been used with effect against successful importers—particularly the Japanese. Although these measures may bring short-term gains, both economic theory and historical experience suggest that they will bring losses in the long term. Protectionism reduces incomes because low-priced goods are excluded to the detriment of current consumers, particularly those with lower incomes. It also reduces employment because restrictions on imports are sooner or later balanced by restrictions on exports as other countries retaliate. It also inhibits the technological dynamism that is the source of long-term growth, by shielding domestic producers from the need that free international competition forces on 171 them: to keep up with all foreign competitors. Text 14. WHY DOES OPENNES MATTER? There are three main reasons why we have to take a much closer look at the interactions between our macro model and the rest of the world: - First, while we have always had net exports in our model, we have not paid attention to all the possible implications of trade imbalances. - Second, financial markets have become more integrated around the world. The high international mobility of financial capital implies that money markets in one country are influenced by what happens in the rest of the world's financial markets. - Third, the exchange rate regime matters for the conduct of monetary policy because it affects the possibilities for arbitrage between domestic and overseas financial markets (and therefore the link between domestic and overseas interest rates). Arbitrage involves buying where a price is low and selling where it is high, in order to make profit. The process of arbitrage tends to drive prices of the same commodity or asset towards equality in different locations. When we talk about capital flows in the context of the balance of payments, we are not talking about imports and exports of capital goods, such as machine tools and heavy equipment. Rather, we are talking about trade in assets and liabilities, such as shares and bonds, or about lending by banks in one country to customers in another. Capital flows matter for two reasons. First net capital flows must be equal in magnitude (but with the opposite sign) to the current account balance. Since this relationship is true by definition, it must always hold. It is important to realize, however, that changes affecting capital flows have implications for net exports (possibly via exchange rate changes), just as shifts affecting net exports have implications for the capital account. The second reason why capital flows matter for the macro model is that they influence the domestic interest rate. If everyone is free to borrow and lend both domestically and internationally, they will borrow where the interest rate is lowest and lend where it is highest. Mobile capital tends to drive the domestic interest rate towards the level of interest rates in world markets. In effect, the domestic economy is close to being a price-taker in world financial markets. Text 15. THE GLOBALIZATION OF FINANCIAL MARKETS Technological innovations in communication and financial liberalization have led to a globalization of the financial services industry over the past few decades. Computers, satellite communication systems, reliable telephones with direct world-wide dialling, electronic mail, and fax machines have put people in instantaneous contact anywhere in the world. As a result of these new technologies, borrowers and lenders can learn about market conditions anywhere in the world and then move their funds instantly in search of the best loan rates. Large firms need transaction balances only while 172 banks in their area are open. Once banks close for the day in each area, the firms will not need these balances until the following day's reopening. So the funds can be moved to another market, where they can be used until IT closes, and then moved to yet another market. Funds are thus free to move from, say, London to New York to Tokyo and back to London on a daily rotation. This is a degree of global sophistication that was inconceivable before the advent of the computer, when international communication was much slower and costlier than it now is. To facilitate the movement in and out of various national currencies, increasing amounts of bank deposits are denominated in foreign rather than domestic currencies. One of the first developments in this movement towards globalization was the growth of the foreign currency markets in Europe in the 1960s. At first the main currency involved was the US dollar. (The market for dollar-denominated bank deposits and loans outside the United States was known as the Eurodollar market—not to be confused with the foreign exchange market in which the euro exchanges for the dollar today.) The progressive world-wide lifting of domestic interest rate ceilings and other capital market restrictions that occurred in the 1980sled toafur-ther globalization of financial markets. Particularly important was the abolition of exchange controls in country after country. The United Kingdom abolished its exchange controls in 1979, Japan did so in 1980, France and Italy in 1989, Spain in 1991, Portugal and Ireland in 1992, and Greece in 1994. Once such restrictions were abolished, the wholesale money markets integrated with the international money markets very quickly. This is because sophisticated borrowers and lenders dealing with large amounts of money have an incentive to shop around for the best terms. The increasing sophistication of information transfer has also led to a breakdown of the high degree of specialization that had characterized financial markets in earlier decades. When information was difficult to obtain and analyse, an efficient division of labour called for a host of specialist institutions, each with expertise in a narrow range of transactions. New developments in communications technology created economies of scale that led to the integration of various financial operations within one firm. For example, in many countries banks have moved into the markets where securities are traded, while many security-trading firms have begun to offer a range of banking services. As the scale of such integrated firms increases, they find it easier to extend their operations geographically as well as functionally. The introduction of the euro in 1999 added further impetus to globalization as it increased the integration of EU financial markets and created a currency that has become an important international instrument. The heavy government intervention in domestic capital markets and government control over international capital flows that characterized the 1950s and 1960s is no longer possible. International markets are just too sophisticated. Globalization is here to stay; and, by removing domestic restrictions and exchange controls, governments in advanced countries were only bowing to the inevitable. 173 Text 16. ANTI-GLOBALIZM In recent years there have been many demonstrations against the World Trade Organisation (WTO), the International Monetary Fund (IMF), and the World Bank. These have been referred to as 'anti-capitalist' or 'anti-globalization' demonstrations. Some of the arguments made by the protesters are difficult to disagree with (like the desirability of reducing poverty in the poorest countries), but others are plain wrong. Virtually all economists, for example, would agree that globalization in the form of greater international trade in goods and services is both wealth- and welfare-increasing, and that closing down international trade would make the world a very much poorer place for all. There have long been debates about free trade, and there have certainly been times when there have been doubts about whether capitalism is the best system. The collapse of communism helped to squash the latter doubts, but the case for a free and open trading system has come under renewed threat in recent years from a number of apparently rational sources. Professor Jagdish Bhagwati of Columbia University identifies four different new critiques that question the benefits of an open trading system: • Demands for 'fair trade' that either mask protectionism or degenerate into it, in both cases charging that free trade lacks fairness and that fair trade restores it. • Concerns that free trade harms the environment. • Charges that free trade (and it chief institution, the WTO) is incompatible with the advancement of social and moral agendas. • Fears that free trade hurts the real wages of workers and that rich countries trading with poor countries create poor in rich countries: and in poor countries, that free trade accentuates poverty. (Bhagwati 2002, page 50) Let us look at each of these issues in turn. Fair trade 'Fair' trade seems hard to object to—who could possibly support 'unfair' trade? One common form of this argument is similar to what used to be called 'the sweated labour fallacy'. This says that we should restrict imports from countries that have lower labour or environ mental standards (in extreme cases using child labour) as this is not fair competition with domestic suppliers. However, to restrict such trade would hurt the poor country, whose best chance of reducing poverty and increasing labour standards is to export to rich countries. So this is just an excuse for protectionism and restricting the benefits that flow from comparative advantage. This is the version of fair trade that Bhagwati criticizes above. There are two forms of the fair trade argument that are less problematic. The first is that industrial countries have pressured some developing countries to open their markets to the products of the richer countries while at the same time imposing restrictions on developing-country exports into rich-country markets. This is a case of uneven bargaining power, and the poorer countries clearly have a good case. The case for free trade has to apply to all and not in one direction only. The second argument for fair trade applies to some products like bananas and 174 coffee, where some charitable groups argue that industrial countries' monopsony power has depressed the prices of commodities. They aim to counter these povertyinducing low prices by offering a 'fair trade' product at a higher price, the revenues from which go to the poor-country producers. Rich-country consumers are free to buy these 'fair-trade' products as they are sold along side comparable but cheaper products in supermarkets. This form of fair trade allows people who so wish to direct charitable giving to specific producers, and there is nothing in economics to say that they should not do this. The only doubt is whether this will catch on in a big enough way to solve the underlying problem. Counteracting monopsony power in commodity markets is likely to require a stronger intervention from governments if this is the true nature of the problem. Notice, however, that our discussion of coffee prices on page 81 points out that the main problem in coffee markets is over-production. Trade and the environment The environment is important for all of us and perhaps will be even more important for our children and grandchildren. Economic analysis clearly shows that free markets may not adequately protect the environment and government intervention is necessary to deliver the social optimum resource use. This applies to many common property resources such as fisheries and rain forests. It also applies to pollution issues like greenhouse gases and acid rain. However, it makes no sense to address environmental problems by closing down world trade. Environmental issues should be handled directly with suitable policies to solve the problem in hand. World trade per se is not the cause of environmental problems. Indeed, the higher standards of living that world trade provides can be helpful in providing the extra output that takes living standards sufficiently above subsistence that quality of life is also in high demand. Social and moral agendas Some politicians have sought to include a 'social clause' in the WTO rules. This would permit the use of trade sanctions against countries whose labour laws or social conventions we did not like. This is presented as a moral crusade to help poor people, but Bhagwati points out that these demands are widely seen as protectionism hiding behind a moral mask. And it is a mistake to bundle together two issues that should be dealt with by separate processes and institutions: 'By trying to kill these two birds (i.e. social agendas and free trade) with one stone (i.e. trade treaties and institutions), you are likely to miss both (Bhagwati 2002, page 69). Rather, he argues, it is important to pursue these different goals in international agencies suited to the specific agendas for which they were set up: 'the WTO for trade liberalization, the International Labour Organization for labour standards, the UN Environment Program for environmental issues, UN1CEF for children's rights, UNESCO for cultural preservation, and so on' (p. 69). Trade is bad for wages There are two elements to this argument depending on whether we are talking about workers in rich countries or poor ones. In rich countries, it is certainly true that some specific workers may be hurt if their employer loses business to cheaper imports from abroad. However, the overwhelming weight of 175 evidence is that the growth of real GDP that is supported by growth in international trade during the past three decades or so has been associated with rising real wages for most classes of worker in the rich countries. Some have tried to argue that trade has hurt unskilled workers in the rich countries, but the case remains unproven, as it is difficult to disentangle the effects of trade from changes in technology that have been occurring at the same time. For the workers in poor countries, here is Bhagwati again: Speaking at least for India, I would say that autarky helped produce a slow average growth rate of 3.5 per cent annually for over a quarter of a century until early 1980s. During this period, it was virtually impossible to pull people up into gainful employment, and out of poverty, in a significantway. With the 1980s, the increasing pace of outward-oriented reforms has been associated with growth rates closer to 6-6.5 per cent annually; and after much controversy, there is a fair degree of consensus that poverty has been dented. Contradicting the anti-free-trade rhetoric that flows ceaselessly from the street theater and even from certain international agencies, the facts show that a shift out of autarky into closer integration into the world economy is producing better, not worse, results for poverty reduction.

Same as visible trade. merger - The uniting of two or more formerly independent firms. merit goods - Goods which the government decides have sufficient merit that more should be produced and consumed than people would choose to do if left to themselves. microeconomics - The study of the allocation of resources and the distribution of income as they are affected by the working of the price system and by the policies of the central authorities. minimum efficient scale (MES) - The smallest level of output at which long-run average cost is at a minimum; the smallest output required to achieve all economies of scale in production. mismatch - See structural unemployment. mixed economy - An economy in which some decisions about the allocation of resources are made by firms and households and some are made by the government. monetarism - The doctrine that monetary magnitudes exert powerful influences in the economy and that control of these magnitudes is a potent means of affecting the economy's macroeconomic behaviour. monetary base- See high-powered money and MO. monetary equilibrium - A situation in which there is no excess demand for or supply of money. 227 monetary policy - Policy of trying to control aggregate demand (and ultimately inflation) via the setting of short-term interest rates. monetary transmission mechanism - The mechanism that turns a monetary shock into a real expenditure shock and thus links the monetary and the real sides of the economy. money - Any generally accepted medium of exchange, i.e. anything that will be accepted in exchange for goods and services. money demand function - The function that determines the demand to hold money balances. money illusion - Refers to behaviour that responds to purely nominal changes in money prices and incomes in either direction, even though real incomes or relative prices have not changed. money income- Income measured in terms of some monetary unit. See also real income. money multiplier - The ratio of the money stock to the monetary base (high-powered money). money price - See absolute price. money rate of interest - The rate of interest as measured in monetary units. money stock - See supply of money. money supply - See supply of money. monopolist - The sole seller in a market. monopolistic competition - A market structure in which there are many sellers and freedom of entry but in which each firm sells a differentiated version of some generic product and, as a result, faces a negatively sloped demand curve for its own product. monopoly - A market structure in which the industry contains only one firm. monopsonist - The sole purchaser in a market. moral hazard - Any change in behaviour resulting from the fact that a contract has been agreed. One example is drivers who drive more recklessly because they have accident insurance; another is employees who do not work hard because employers cannot monitor their performance effectively. multinational enterprises (MNEs) - See transnational corporations. multiplier - The ratio of the change in GDP to the change in autonomous expenditure that brought it about. multiplier-accelerator theory - An element of business-cycle dynamics caused by the interaction of the multiplier and the accelerator, which can make the economy follow a cyclical path in response to a one-off exogenous shock. NAIRU - The amount of unemployment (all of it frictional or structural) that exists when GDP is at its potential level and that, if maintained, will result in a stable rate of inflation. The acronym stands for 'non-accelerating-inflation rate of unemployment'. In the long run the NAIRU is equivalent to the natural rate of unemployment. 228 Nash equilibrium - In the case of firms, an equilibrium that results when each firm in an industry is currently doing the best that it can, given the current behaviour of all other firms. Nash theorem - Theory that every game with a finite number of players and a finite number of strategies will have at least one Nash equilibrium (so long as some random element to strategies is possible). national debt - The debt of the central government. national income - In general, the value of the nation's total output, and the value of the income generated by the production of that output. Measured in practice by gross national income and assumed in most of this book to be equivalent to GDP. national product - A generic term for the nation's total output, which might be measured more specifically by GDP.
