Injections: Investment and purchase of exports Expenditures / revenue Product market Goods/Services Taxes Households Goods/services Taxes Government Goods/services Firms Factors of productin Resource market Income: W I R P Leakages: Savings and purchase of imports Leakages: The money that leaves the circular flow because it is not being spent on domestic G&S. Injections: Spending that enters the circular flow from external sources i.e. foreign investors and consumers. Macroeconomics The Macroeconomic Objectives In Microeconomics, the objectives are: ·firms aim to maximize profits ·consumers aim to maximize utility ·efficient resource allocation in competitive markets ·the correction of market failure through government intervention These can be thought of the goals of microeconomics In Macroeconomics, the objectives are: 1) Full - employment: Does NOT mean every single person has a job. Means 2) Stable prices: This refers not to the prices of individual products, but to the 3) Economic growth: The most talked about macroeconomic goal, growth occurs 4) Income distribution: A nation's income should be somewhat equally distributed that most people who want to work are working. Some unemploymenet will exist in a healthy economy. price level in the economy as a whole. A rise in the overall price level is called inflation, a fall is called deflation. when the total amount of goods and services an economy produces increases from year to year. between the upper and lower "classes" in society. Some tax systems are designed to achieve more equitable income distribution. Macroeconomics Measuring national income Gross Domestic Product: GDP is the monetary measure of the total market value of all final goods and services produced within a country in one year. Can be thought of as: national income or national output or national expenditures GDP=primary output + GDP=W+R+I+P secondary output + tertiery output GDP=C+I+G+(X-M) Why is GDP important? >> It tells us something about the relative size of different countries' economies >> It is a monetary measure, so it tells us how much income a country earns in a year (assuming everything that is produced is sold). >> When we divide GDP by the populuation, we get GDP per capita, which tells us how many goods and services the average person consumes in a country. >> When real GDP grows more than the population, that tells us that people on average, have more stuff than they did before. >> If you believe that having more stuff makes people better off, then GDP per capita tells us how well off people in society are. IMPLICATIONS: GDP is the most important macroeconomic measurement! Macroeconomics Measuring national income What's included and not included in GDP? GDP includes: ·GDP includes only final products and services ·GDP is the value of what has been produced within the borders of a nation over one year, not what was actually sold. GDP Excludes "nonproduction transactions": ·Purely financial transactions are excluded. >>Public transfer payments, like social security or cash welfare benefits. >>Private transfer payments, like student allowances or alimony payments. >>The sale of stocks and bonds represent a transfer of existing assets (However, the brokers’ fees are included for services rendered.) ·Secondhand sales: If I buy a used car in 2008, that sale does not count towards 2008's GDP, because the car was not made in 2008! The price of the car was originally included in the year's GDP when it was produced. Macroeconomics Measuring national income Gross National Product: the total income that is earned by a country's factors of production regardless of where the assets are located. GNP = GDP + net property income from abroad The value of the cars made in a Honda factory in the US count towards Japan's GNP and America's GDP. Bank of America's operations in Japan count towards US GNP and Japan's GDP. Nominal GDP and real GDP: Nominal GDP measures the money value of a nation's output. To measure the REAL value of the nation's output, the value of money must be taken into account. Inflation erodes the value of money and therefore the nation's output. REAL GDP = Nominal GDP adjusted for inflation. Macroeconomics Measuring national income GDP: How is it measured? Two methods are used for measuring GDP Expenditures approach: Measures all the spending on final goods and services that has take place during a year. This includes: Personal Consumption (C): the purchase by households of all goods and services ·Including non-durables: bread, milk, toothpaste, t-shirts, socks, toys, etc... ·and durables: TVs, computers, cars, refrigerators, etc... ·and services: dentist visits, haircuts, taxi rides, accountants, lawyers, etc... Gross Private Domestic Investment- (Ig) ·All final purchases of machinery, equipment, and tools by businesses. ·All construction (including residential). ·Changes in business inventory. >>If total output exceeds current sales, inventories build up. >>If businesses are able to sell more than they currently produce, this entry will be a negative number. Macroeconomics Measuring national income Components of GDP, continued... Government Purchases (of consumption goods and capital goods) - (G) ·Includes spending by all levels of government (federal, state and local). ·Includes all direct purchases of resources (labor in particular). ·This entry excludes transfer payments since these outlays do not reflect current production. Net Exports- (NX) ·All spending on goods produced in the U.S. must be included in GDP, whether the purchase is made here or abroad. ·Often goods purchased and measured in the U.S. are produced elsewhere (Imports). ·Therefore, net exports, (Xn) is the difference: (exports - imports) and can be either a positive or negative number depending on which is the larger amount. Summary: GDP = C + I + G + NX (X-M) Macroeconomics Evaluating GDP Shortcomings of GDP: GDP is reasonable and useful in measuring how well or poorly the economy is performing but it has some shortcomings: ·Certain important work is left out of accounting (homemakers, labor of carpenters who make own homes because GDP measures only the MARKET VALUE of output. GDP therefore is understated. ·Our accounting system does not take reflect that we work less hours than in past years (1900 avg was 53 hours) and that we have more leisure time ·Does not reflect improved product quality ·Does not include the underground economy ·GDP does not put a market value/cost on the environment. Higher GDP may be accompanied by negative externalities, which are NOT subtracted from GDP. ·GDP does not tell us if the best combo of G and S are produced, weighs G and S equally, a rifle and encyclopedias are assigned equal weight. ·Nor does it measure how GDP is distributed in among the population ·GDP does not measure the total well being, happiness, a reduction of crime or better relationships with society, with other countries, etc... Macroeconomics Measuring national income How do we determine Real GDP? We will assume that we live in an economy that produces only one thing, Pizza.. 1. Find Nominal GDP for each year 2. Determine a price index for each year (using the price index formula), 3. Adjust the nominal GDP figures by dividing by the price index (in hundredths). What is a price index? A price index is a measure of the price of a specified collection of goods and services called a, “market basket” in a given year as compared to the price of an identical basket of goods and services in a reference year. Price of a "market basket" of goods in a specific year Price index for a given year Real GDP = = Price of same "basket" in the base year Nominal GDP Price index (in hundredths) X 100 Macroeconomics Measuring national income Example: 2008: 10 pizza's @ $10/pizza. Nominal GDP = $100 2009: 12 pizza's @ $12/pizza. Nominal GDP = $144 What is the REAL GDP in 2009? P pizza Price index= 2009 = $12 Ppizza 2008 = $10 =1.2 x 100 = 120 Nominal GDP in 2009 = 12 x $12 = $144 Real GDP in 2009 = $144 1.2 = $120 Conclusions: Because the price of pizza's increased by 20% (inflation rate was 20%), the nominal GDP growth of 44% was over-stated. After adjusting for inflation, the nations' growth rate is only 20% Macroeconomics Inflation Measuring Inflation: Inflation is defined as a persistent increase in the average price level in the economy, usually measured through the calculation of a consumer price index (CPI) This year’s CPI - last year’s CPI Rate of inflation = Last year’s CPI X 100 Example: Assume our economy produces only pizzas. Therefore, the "basket of goods" our CPI will use consists of one pizza. In a real economy the basket of goods would be made up of hundreds of consumer products from utilities to automobiles to petrol to shoes and electronics. 2008: Ppizza = $10 2009: Ppizza = $12 12-10 X 100 = Rate of inflation = 10 20% Macroeconomics Inflation Degrees of inflation: Not all inflation is bad. Some inflation is considered an indication of a healthily growing economy. However, high inflation is clearly undesirable as it erodes the value of people's incomes and the nation's output. ·Single digit inflation is called moderate inflation. ·Rapid inflation of double digits is called galloping inflation ·Extremely high inflation exceeding 50% per month, is called hyperinflation. Deflation: A persistent fall in the average level of prices in the economy. Deflation sounds like a good thing at first because it means the real values of people's incomes are rising. However, deflation leads to a disincentive for firms to increase production, meaning they will cut back output, lay off workers, leading to a recession and rising unemployment. “the Rule of 70”: 70 / inflation rate = # years for the price level to double) Interpretation: In a country experiencing 5% inflation, the price level will double in only 14 years. If inflation reaches 10%, prices will double in only 7 years. Inflation and Unemployment Costs of inflation Inflation's effects on the economy: Inflation is one of the "evils" in macroeconomics. In fact, price level stability is one of the three main goals of macroeconomic policy. Inflation's effects include: ·Loss of purchasing power: As prices rise and incomes do not, people are becoming poorer in real terms. Real income is nominal income minus inflation. An inflation rate of 10%, for example, accompanied by no change in nominal incomes would mean the average household was 10% poorer at the end of the year than at the beginning. ·Loss of savings: Savers are negatively effected by inflation. If you put $1000 in the bank at 5% interest today, but there is inflation of 10% in the next year, then you will have actually lost 5% of your savings. The real interest rate is the nominal interest rate minus the rate of inflation. ·Higher interest rates for borrowers: In times of high inflation, banks will raise the interest rates they charge borrowers. A lender charging 4% interest when there is inflation of 6% will actually be paid back in money worth 6% less than the money originally lent. To maintain profits, banks must charge a higher nominal interest rate than the rate of inflation, making it more costly for firmst and households to borrow financial capital. ·Effect on international competitiveness: High inflation at home makes domestic output less attractive to foreigners, and imports more attractive to domestic consumers. This could move a country's trade balance towards deficit. Inflation and Unemployment the Phillips Curve ·In the short-run, there is an inverse relationship between the price level and the unemployment rate ·When AD is weak, unemployment will increase and there is downward pressure on prices. ·When AD is strong, unemployment falls and there is upward pressure on prices as the economy approached fullemployment. ·When economy is at equlibrium, UE will be stable at the Natural Rate of Unemployment Inflation (ΔPL) Graphing the inflation/unemployment relationship: the Phillips Curve 8% P fe 2% PC 2% NRU 8% Unemployment Macroeconomics Inflation Causes and theories of inflation: ·Demand-pull inflation: an excess of total spending beyond the economy’s capacity to produce. When resources are already fully employed, firms cannot respond to increases in demand. “Too much spending chasing too few goods.” ·Cost-push or supply-side inflation: Prices rise because of rise in per-unit production costs (Unit cost = total input cost/units of output). >>Wage-push can occur as result of union strength. And Supply shocks may occur with unexpected increases in the price of raw materials. >>Cost push; experience has shown that rising prices and unemployment can exist together, it is called stagflation Complexities: It is difficult to distinguish between demand-pull and cost-push causes of inflation, although cost-push will die out in a recession if spending does not also rise. Macroeconomics Inflation The Output Effects of Inflation ·Cost-push inflation, where resource prices rise unexpectedly, could cause both output and employment to decline. Real income falls. Real income is nominal income /price index ·Mild inflation (<3%) has uncertain effects. It may be a healthy by-product of a prosperous economy, or it may have an undesirable impact on real income. ·Danger of creeping inflation turning into hyperinflation, which can cause speculation, reckless spending, and more inflation The Redistributive effects of inflation: Who is hurt? 1. Fixed-income groups will be hurt because their real income suffers. Their nominal income does not rise with prices. 2. Savers will be hurt by unanticipated inflation, because interest rate returns may not cover the cost of inflation. 3. Creditors: Unanticipated inflation hurts creditors. Who benefits? Debtors (borrowers) Interest payments may be less than the inflation rate Is there any “cushioning” for inflation built into the economy? ·If inflation is anticipated, the effects of inflation may be less severe, >>since wage and pension contracts may have inflation clauses built in >>interest rates will be high enough to cover the cost of inflation to savers Ex; “Inflation premium” is amount that interest rate is raised to cover effects of anticipated inflation. >>“Real interest rate” is defined as nominal rate minus inflation premium. Macroeconomics Unemployment Four broad Macroeconomic Goals: 1) Full-employment (low unemployment) 2) Price level stability (low inflation) 3) Economic growth (increase in real GDP year on year) 4) Income distribution Measuring unemployment: The unemployment rate is the number of people who are unemployed (actively seeking employment but unable to find work) expressed as a percentage of the total labor force. Labor force: "the economically active population", usually between the ages of 16-64 Part-time workers are counted as “employed.” “Discouraged workers” who want a job, but are not actively seeking one, are not counted as being in the labor force, so they are not part of unemployment statistic. This means that most country's unemployment data is skewed, i.e. it may underestimate the number of people who are truly unemployed. Inflation and Unemployment Unemployment Types of unemployment: Unemployment is defined as the percentage of the labor force out of work. The labor force is made up of 16-65 year olds who are employed or seeking employment. Frictional: Describes workers "in between jobs". When someone with marketable skills moves from one job to another. Usually thee months or less. Seasonal: Describes workers who work at jobs that are seasonal in nature. Examples include fruit pickers, migrant workers, resort employees, etc... Structural: When workers lose their jobs due to the changing macroeconomic structure of the economy. Factory workers who lose their jobs due to automation are structurally unemployed. Structural unemployment is difficult to overcome for those who experience it, but may be evidence of a healthy economy, since often those who are structurally unemployed are less skilled. Frictional + Seasonal + Structural UE = Natural Rate of Unemployment (NRU) Cyclical: Workers who lose their job due to a recession caused by weak aggregate demand are cyclically unemployed. Cyclical unemployment is a sign of a struggling economy. The nearly 10% unemployment in the United States in 2009 is a result of recession and the changing structure of the US economy. Macroeconomics the Business Cycle the Business Cycle Level of real output Four phases of the business cycle are identified over a several-year period: 1.A boom is when business activity reaches a temporary maximum with full employment and near-capacity output. 2.A recession is a decline in total output, income, employment, and trade lasting six months or more. 3.The trough is the bottom of the recession period. 4.Recovery is when output and employment are expanding toward full-employment level. Boom Boom Boom Trough Trough Time Theories about causation: ·Major innovations may trigger new investment and/or consumption spending. ·Changes in productivity may be a related cause. ·Most agree that the level of aggregate spending is important, especially changes on capital goods and consumer durables. ·Cyclical fluctuations: Durable goods output is more unstable than non-durables and services because spending on latter usually can not be postponed. Blog posts: “Business cycle” Macroeconomics Unemployment Types of unemployment: Frictional or seasonal unemployment consists of those searching for jobs or waiting to take jobs soon; it is regarded as somewhat desirable, because it indicates that there is mobility as people change or seek jobs. Structural unemployment: due to changes in the structure of demand for labor; e.g., when certain skills become obsolete or geographic distribution of jobs changes; examples, Glass blowers were replaced by bottle-making machines., Oil-field workers were displaced when oil demand fell in 1980s, Airline mergers displaced many airline workers in 1980s.,Foreign competition has led to downsizing in U.S. industry and loss of jobs. Cyclical unemployment is caused by the recession phase of the business cycle, which is sometimes called deficient demand unemployment Macroeconomics Unemployment Definition of “Full Employment”: Full employment does not mean zero unemployment. but is equal to the total of frictional and structural unemployment When the economy is at full-employment, the natural rate of unemployment or NRU prevails in the economy. With some unemployment, the economy still has room to grow in the short-run, as there are some workers available for firms to hire if they wish to expand output. The NRU is achieved when labor markets are in balance ·At this point the economy's potential output is being achieved. ·The natural rate of unemployment is not fixed, but depends on the demographic makeup of the labor force and the laws and customs of the nations. Historically, Western European nations have a higher NRU than the US and East Asian economies WHY? ·Better "social safety net" in Western Europe means that when workers are unemployed, they receive more government support and benefits. ·The incentive is not as strong in such economies to seek employment than in countries with few social safety nets. ·In the US, unemployment benefits expire after only 3 months of collecting them. The incentive, therefore, is to find work as quickly as possible in the US, whereas in France unemployment benefits can be collected for much longer. Macroeconomics Unemployment Economic cost of unemployment: ·GDP gap and Okun’s Law: GDP gap is the difference between potential and actual GDP. >>Economist Okun quantified relationship between unemployment and GDP as follows: For every 1 percent of unemployment above the natural rate, a 2 percent GDP gap occurs. This has become known as “Okun’s law.” ·Unequal burdens of unemployment exist. Examples: >>Rates are lower for white-collar workers than blue-collar, >>teenagers have the highest rates, >>blacks have higher rates than whites, >>less educated workers, on average, have higher unemployment rates than workers with more education. ·Non-economic costs include loss of self-respect and social and political unrest. Macroeconomics Economic Growth Measuring economic growth: Economic growth is achieved when there is an increase in a nation's real income and output in a given year. Real GDP in year 2 - Real GDP in year 1 GDP Growth rate = X 100 Real GDP in year 1 Example: Switzerland's real GDP in 2008: $309 billion Switzerland's real GDP in 2007: $305 billion Switzerland's GDP growth rate 309b - 305b = .019 X 100 = 1.9% 305b Per-capita economic growth: If population grows faster than GDP, then the average person may be worse off even with real economic growth. Example: If real GDP increases by 3% while population increases by 2%, then real GDP per capita has only increased by 1% Macroeconomics Measuring Economic Goals PPC analysis of Macroeconomic goals: The simple production possibilities curve can be used to illustrate three of the economic goals Consumer goods Switzerland D B Full-employment output: The economy is producing just inside its PPC, the NRU prevailes C Economic growth: A point beyond the nation's PPC represents what could be attained through economic growth Inflationary gap: The economy is producing beyond full-employment at less than NRU. Competition for workers puts upward pressure on prices. A Deflationary gap: when the economy is producing below full-employment. Low aggregate demand and high unemployment puts downward pressure on prices Capital goods Practice Measuring Macroeconomic Goals: NCEE activity 11 Macroeconomic Models Aggregate Demand Determinants of aggregate demand: CONSUMPTION is determined by the following factors Wealth: When value of existing wealth (real assets and financial assets) increases, households increase C and decrease S. When wealth decreases, C decreases and S increases. Expectations: of future prices and incomes. If households expect prices to rise tomorrow, then today C will shift up, S down. If we expect lower income in the future, then C will likely shift down and S shift up, as households choose to save more for the hard times ahead. Real Interest Rates: Lower real interest rates lead to more C, less S and vise versa. Household Debt: When consumers increase their debt level, they can consume more at each level of DI. But if Debt gets too high, C will have to shift down as households try to pay off their loans. Taxation: Increase in taxes shifts BOTH C and S curves downwards. Decrease in taxes shifts both C and S curves upwards. This will be covered more when we discuss Fiscal Policy. Changes in any of these factors increase or decrease Consumption, shifting the Aggregate Demand curve Macroeconomic Models Aggregate Demand Determinants of aggregate demand: INVESTMENT is determined by the following factors Real interest rates and expected rate of return: there is an inverse relationship between real interest rates and the level of investment in the economy ·Profit-maximizing firms will only invest in new capital if the expected rate of return on an investment is greater than the real interest rate. ·If a firm expects the return on an investment to be 5% and the real interest rate is 3%, the firm will invest. If expected returns are 5% and real interest rate is 7%, the firm will not invest. Investor confidence, influenced by: ·Expectations of future sales and business conditions ·Technology: increases the productivity of capital, thereby encouraging new investment ·Business taxes: higher taxes decrease the expected return on new capital, discouraging new investment ·Inventories: the existence large inventories will discourage new investment ·Degree of excess capacity: If firms can easily increase output because they are producing below full capacity, they will be less likely to invest in new capital Macroeconomic Models Aggregate Demand Determinants of aggregate demand: EXPORTS are determined by the following factors Incomes abroad: As incomes in nations with which a nation trades increase, demand for the country's exports will increase, shifting Aggregate demand out. Exchange rates: A weakening of a country's currency relative to other currencies will make its exports more attractive, increasing its net exports and shifting aggregate demand out. Tastes and preferences: If foreign tastes and preferences shift towards a nation's products, exports will increase, shifting aggregate demand out. Macroeconomic Models Aggregate Demand Determinants of aggregate demand: GOVERNMENT SPENDING changes in the following situations. Fiscal policy: Changes in government spending and/or taxation aimed at increasing or decreasing aggregate demand Expansionary fiscal policy: A decrease in taxes and/or an increase in government spending. ·Used in times of weak aggregate demand, high unemployment and falling output. ·Public sector spending (G) is needed to replace the fall in private sector spending (C, I, Xn) ·Expansionary effect of fiscal policy depends on the size of the spending multiplier. The greater proportion of new income households use to consume domestic output, the greater the expansionary effect of a tax cut or an increase in government spending Macroeconomic Models Aggregate Supply Aggregate Supply: The Keynesian vs. Classical debate Background to the Keynesian view of the AS curve: John Maynard Keynes was an English economist who represented the British at the Versailles treaty talks at the end of WWI. Keynes argued that the Allies should invest in the reconstruction of Germany and opposed the reparations being forced upon Germany after the war. When the Allies insisted on forcing Germany to pay reparations, Keynes walked out on the Versailles talks. If they had listened to Keynes, the Allies could have potentially avoided the second World War. Keynes believed that during a time of weak spending (AD), an economy would be unable to return to the full-employment level of output on its own due to the downwardly inflexible nature of wages and prices. Since workers would be unwilling to accept lower nominal wages, and because of the role unions and the government played in protecting worker rights, the only thing firms could due when demand was weak was decrease output and lay off workers. As a result, a fall in aggregate demand below the full-employment level results in high unemployment and a large fall in output. To avoid deep recession and rising unemployment after a fall in private spending (C, I, Xn), a government must fill the "recessionary gap" by increasing government spending. The economy will NOT "self-correct" due to "sticky wages and prices", meaning there should be an active role for government in maintaining full-employment output. So which theory is right, Classical or Keynesian? Demand and Supply-Side Policies Monetary Policy (AP only) The US Federal Reserve System: Who's in charge of monetary policy in the US? The Federal Reserve: America's Central Bank ·12 banks located in different regions of the country ·Coordinated by the Fed's Board of Governors ·Bankers' banks: Provide banking services to commercial banks >>accept deposits >>lend money (called the "discount window", only if commercial banks can't borrow from one another would they borrow from the Fed) >>Issue new currency to commercial banks ·FOMC - Federal Open Market Committee: 12 individuals, including the Chairman of the Fed (Bernanke). Purpuse is to buy and sell government securities to control the nation's money supply and influence interest rates. Execute monetary policy. Fed Functions and the Money Supply ·Issue currency: the Fed can inject new currency into the money supply by issuing Federal Reserve Notes (dollars) to commercial banks to be loaned out to the public. ·Setting reserve reuirements: this is the fraction of checking account balances that commercial banks must keep in their vaults. The larger the reserve requirement, the less money commercial banks can loan out. ·Lending money to banks: The Fed charges commercial banks interest on loans, this is called the "discount rate". ·Controling the money supply: this in turn enables the Fed to influence interest rates. Demand and Supply-Side Policies Monetary Policy (AP Only) Three Monetary Policy tools: Relative importance OMO - Open-market operations is the buying and selling of government bonds in the financial market. Because it is the most flexible, bond holdings by the central bank can be adjusted daily, and have an immediate impact on banks' reserves and the supply of money in the economy Reserve ratio: The RR is RARELY changed. RR in the US has been .10 since 1992. Reserves held by the Central Bank earn no interest, so if RR is raised, banks' profits suffer dramatically since they have to deposit more of their total reserves with the Fed where they earn no interest. Banks prefer to be able to lend out as much of their total reserves as possible Discount rate: Until recently, the discount rate in the US was rarely adjusted on its own, and instead hovered slightly above the federal funds rate*. In 2008, the US Fed lowered the discount rate to very low levels as uncertainty among commercial banks brought private lending to a halt. The "discount window" is only supposed to be used in the case of private lenders being unable to acquire funds, hence the Fed is the lender of last resort Discount rate called into action - March 17, 2008... "The Federal Reserve announced a series of steps Mar. 16 to help provide relief to a spreading credit crisis that threatens to plunge the economy into recession: The central bank approved a cut to its lending rate to financial institutions, from 3.5% to 3.25%, and created another lending facility for big investment banks to secure short-term loans." *Federal Funds Rate: The interest rate that banks charge one another on overnight loans made from temporary excess reserves. Demand and Supply-Side Policies Monetary Policy (AP only) Money Creation: What does it mean to create money in a modern economy? Fractional reserve banking - How banks create money: By accepting deposits from households, then lending out a proportion of those deposits to borrowers, which themselves end up being deposited and lent out again and again, BANKS CREATE NEW MONEY through their every-day activities. A bank begins operations by accepting deposits from savers: Bank must keep reserve deposits in its district Federal Reserve Bank. ·Banks can keep reserves at Fed or in cash in vaults. ·Banks keep cash on hand to meet depositors’ needs. ·Required reserves are a fraction of deposits, as noted above. Other important points: ·Excess reserves: Actual reserves minus required reserves are called excess reserves. This is the portion of total reserves that a bank is allowed to lend out. ·Control: Required reserves do not exist to protect against “runs,” because banks must keep their required reserves. Required reserves are to give the Federal Reserve control over the amount of lending or deposits that banks can create. In other words, required reserves help the Fed control credit and money creation. ·Banks cannot loan beyond their required required reserves ·Asset and liability: Reserves are an asset to banks but a liability to the Federal Reserve Bank system, since now they are deposit claims by banks at the Fed.
