ECN202: Macroeconomics 1970s: Experiments with MoneyThe International Dimension “the memory of the Great Depression meant that the US was highly likely to suffer an inflationary episode like the 1970s in the post-World war II period-maybe not as long, and maybe not exactly when it occurred, but nevertheless a similar episode." 1970s Setting The signature 1970sgraph is of real earnings which shows the decade marked the end of the rise in post WWII earnings for American workers. In part this was driven by demographics as baby boomers began to enter the labor market, and in part by the rise of foreign competition as the world continued to get flatter. Countries the US helped rebuild after WW II were now rebuilt and offering competition to American companies and workers. And we can’t forget OPEC, which became a household word after it caused two painful oil crises that marked the end of cheap oil. In terms of public policy, the federal government continued to expand with creation of the EPA and the Departments of Energy and Education, and passage of Roe v Wade. It was also the decade of Watergate and the end of the Vietnam War. 1970s in Macro In macroeconomics the 1970s was quite the decade – the only period of sustained peacetime inflation in US history and an economy that performed badly enough to produce only the second ideological shift in this country’s history. Just as the conservatives could not solve the economic problems of the 1930s, liberals could not solve the economic problems of the 1970s. This ideological void opened the to conservatives led by the Chicago School economists including Milton Friedman who stepped in to fill that void. In this unit we will look at this ideological shift with a focus on the international monetary system and the domestic monetary system where the most significant changes took place in the 1970s. S&D again – and again At the center of this unit is money, one of the greatest inventions - money. Some money is involved in international transactions –you buy that Chinese T-shirt and some is part of domestic transactions –you get that student loan. In both cases there is a price – the exchange rate for those international exchanges and the interest rate for the domestic one. In this unit we look at the two markets to understand these two prices as you can see in the diagram that follows. The key to understanding these markets is the same as always – pay attention to the details. You need to follow the rules and you will be able to understand those two important prices – exchange rates and interest rates. 1970s unit Money evolution International / Exchange rates Gold Bretton Woods Domestic / interest rates Flexible Keynesians S&D (e) S&D (r) Classical / monetarists Foreign Exchange Market e* Domestic Money Market r* 1970s International The 70s opened with the US running out of gold, which forced president Nixon to abandon the Bretton Woods system and adopt a flexible exchange rate. The US $’s value would now be determined in a market rather than by the government. We begin with a brief overview of the “Books” so you will better understand Nixon’s dilemma and the nature of international trade. To facilitate the trade recorded in those books, we need an international monetary system, and here we look at the evolution of these systems that all possess one imperfection – the trilemma. Special emphasis is placed on the flexible exchange rate system and the euro experiment plus we examine MAD II, a modern version of MAD that dominated life when I was in school. To give you an idea of the unit, here are a few headlines related to topics in the unit. In the news: those pesky exchange rates 1. “U.S. to Press Saigon for Devaluation of Piaster to a More Realistic Exchange Rate” 1970 2. “The dollar reached an all-time exchange-rate high of 634 lire at the Milan foreign exchange today in the third straight increase from the floor level.” 1970 3. “'Undervalued' Yen Held Target Of Nixon Surcharge on Imports” 1971 4. “Stable Exchange Rates in Wind? Pragmatism Is Now the Catchword In Currency” 1975 5. “U.S. Tries to Reassure Its Allies New Deficit Won't Depress Dollar” 1978 In the news: and “meddling” governments 6. “THE world had a fright last fall when the dollar, the currency that holds the world monetary system together, suffered a severe sinking spell.” 1979 7. “Japan acts alone to weaken its currency” 8. “Joining Switzerland, Japan acts to ease currency’s strength” 9. “Dollar’s fall tests nerve of Asia’s central banks” 10.“When weakness is strength” 11.“Talk in Japan shakes dollar and Treasuries” 12.“Germany’s export prowess weighs on euro-zone” 13.“Will the euro survive?” 14.“Europe tries to lure Chinese cash to rescue euro” To trade or not to trade We looked at this question before, so we know the answer. There are benefits and costs to trading – and to not trading – but we live in a world where the movement is toward more trade as you can see in the graphs that follow. In the map that follows you can see countries have developed their own language and eventually we needed translators to bridge the language differences. The same is true with trade – countries developed their own currencies so we needed to bridge the individual monetary systems to facilitate trade. In fact we needed two systems – an international accounting system and an international monetary system. In the beginning!!

In fact there are many different measures of balance as you can see below. The Balance on Goods measures the difference between imports and exports of “stuff.” A deficit would mean that we import more than we export so money flows OUT.

If we run a Current Account deficit ( US $s flowing out) then we run a Capital Account surplus ( US $s flowing in) US Capital Account Transactions - U.S.-owned assets abroad, net (increase/financial outflow (-)) Direct investment & Foreign securities US investors buy stock on China’s stock exchange US government buys Japanese yen. US firm buys European company + Foreign-owned assets in the United States, net (increase/financial inflow (+)) U.S. Government securities & Direct investment English investors buy stock on US stock exchange China’s government buys US Treasury securities.

Build an International Monetary System Desirable features of international monetary system 1. free flow of capital (money) 2. stable exchange rates 3. control of the domestic money supply Trilemma - you only get 2 features Evolution of international monetary system 1. Gold standard (1717-1945) Give up control of Ms Ends with Great Depression and WWII 2. Bretton Woods (1946 -1971) Restrict capital flows Ends in early 1970s with Nixon’s closing of gold window 3. Flexible exchange rates (1972- ) Give up fixed exchange rates Case Study: England’s options after wartime inflation made its goods too expensive England’s Situation after War Goals 1.Mobility of capital 2.Fixed exchange rate 3.Control of Ms Trilemma (only 2 goals possible) Three Possibilities 1.Give up control of money supply 2.Devalue the currency 3.Restrict capital flows Option 1: Give up control on money supply (gold standard) 1. 2. 3. 4. 5. Price of shirt rises in UK during war UK imports rise and UK exports fall UK runs trade deficit and gold leaves UK Outflow of gold reduces money supply Lower money supply means lower prices and lower wages and higher unemployment and trade imbalance is eliminated BUT UK loses control of its money supply but problem is solved Option 2: Devalue currency 1. Price of shirt rises in UK during war 2. Devalue UK currency / increase price of gold 1. lower value of currency means exports look cheaper and imports look more expensive 2. Lower price for exports means rise in exports & higher prices of imports reduces imports 3. Trade deficit eliminated UK loses control of its currency value, but the deficit is eliminated Option 3: Restrict capital flows 1. Price of shirt rises in UK during war and UK consumers want to buy shirts outside of UK 2. Government simply refuses to allow currency to leave country to buy imported shirts UK loses control of its capital mobility, but solves the deficit problem Case Study: Nixon’s Problem In the early 1970s president Nixon had two overriding goals - Reelection in 1972 and Maintaining an “image” of strength in Cold War. He also faced some very real problems. 1. High unemployment & stubborn inflation and the Phillips Curve indicated there was no easy solution 2. High foreign military spending (Vietnam War) needed to “contain” communism = US $s flow out 3. US households had a high demand for imports & for foreign travel = US $s flow out 4. Trade surplus disappearing meant US gold supply was falling – US was running out of gold Nixon’s Problem: Trade Surplus disappears Nixon’s 3 BAD 1971 options (trilemma) 1. Devalue $ – bad for image of superpower 2. Restrict capital flows – bad for image of superpower 3. Reduce outflow of gold by 1. Reducing military spending abroad & bring home troops - bad for image 2. Increasing exports - raise tariffs – bad for image and against “rules” of post WWII free trade 3. Reducing consumers’ import spending by creating a recession - bad for election Nixon’s Choice: New Economic Policy Nixon surprises everyone. First, a conservative Republican orders wage-price freeze meaning the government and not markets would set prices. Second, he abandons the gold standard and blames speculators. By abandoning the gold standard the US $’s value would now be set in the market, so now we will look at that market. 1."NIXON ORDERS 90-DAY WAGE-PRICE FREEZE, ASKS TAX CUTS, NEW JOBS IN BROAD PLAN: SEVERS LINK BETWEEN DOLLAR AND GOLD." headline of the New York Times on August 16, 1971 Understanding Flexible Exchange Rates Remember the Cookbook approach to S&D. Now you need to follow the rules once again. Below are the “Rules of the foreign exchange game.” It may seem slow, but follow the rules carefully if you are to avoid the common pitfalls of those who have come before you. “Rules of the game” 1. 2. 3. 4. Specify exchange rate Identify participants Identify determinants of behavior Convert into S&D diagram Specify the Exchange Rate There are two ways to specify the price of the US$, what some would refer to as the value of dollar or the exchange rate. 1. the number of units of a foreign currency needed to buy a dollar (ex. 97 ¥ per US $). 2. the number of US $s to buy one unit of a foreign currency (ex. $1.3 per 1 €) In the next four slides you will see a few examples. When we talk about the value of the US $ we will be using the approach used in the Japan and Swiss examples. # US $s to buy a euro What does this rise here mean about the value of the US $? The US $ is getting weaker = more US $s to buy the foreign currency # US $s to buy a UK £ What does this decline here mean about the value of the US $? The US $ is getting stronger= fewer US $s to buy the foreign currency # US $s to buy a euro What does the decline here mean about the value of the US $? The US $ is getting weaker = less foreign currency to buy the US $ # US $s to buy a euro What does this rise here mean about the value of the US $? The US $ is getting stronger = more foreign currency to buy the US $ 2. Identify the players There are four major players in the foreign exchange market. 1.US consumers who want to buy foreign “Stuff” 2.Foreign consumers who want to buy US “Stuff” 3.US investors who want to buy foreign “assets. 4.Foreign investors who want to buy US assets 3. Specify determinants of players’ behavior Everyone wants their own currency. German workers want euros while the US government wants US dollars when it sells Treasuries to British investors. 1.US consumers purchases of foreign “Stuff” depends upon US income and wealth 2.Foreign consumers purchases of US “Stuff” depends upon foreign income and wealth 3.US investors who buy foreign “assets are looking for good returns = high interest rates abroad. 4.Foreign investors who buy US “assets are looking for good returns = high interest rates in US. 4. Convert into graphs supply of dollars is generated every time someone in the US tries to buy goods, services or assets from abroad. Americans must go to the international money market where they will supply US dollars to the money market to finance their purchases of foreign goods and assets. Supply curve has + slope because as $ increases in value, imports look cheaper to Americans so imports to the US increase which means more $s being supplied to the international money market.

Foreigners will need to go to the international money market where they will demand US dollars in the money market in order to finance their purchases of US goods and assets. As $ increases in value US exports look more expensive so exports decrease which means fewer $s being demanded on the international money market.

Every movement in the exchange rate coincides with a shift in either the S or D curves in the foreign exchange market. For example, in the 1975-1978 period the value of the US dollar is falling.

China is special because it has tried to hold its exchange rate constant and override the influences of S&D, which is why it is accused of being a currency manipulator. Europe has embarked on an experiment in which a number of countries have given up control of their own money supply and currencies and adopted a common currency – the euro (€). China What is happening? Why would China try to keep the exchange rate at 8 instead of letting it fall to 4 yuan per US$? The answer can be seen with the simple example – the US price of a China T-short. Tshirt costs 16 yuan in China @ exchange rate of 8 costs $2 Tshirt costs 16 yuan in China @16 yuan @ exchange rate of 4 costs $4 Question: How does China manipulate its currency? You can see in the next slide that at the exchange rate of 8 the US has a trade deficit with China so US$s are flowing out of the country as we buy China’s exports. This would put downward pressure on the US $ increase the value of the yuan. The only thing China can do is to offset the outflow of $s by using them to buy US assets. So we buy Chinese toys and computers and they buy US Treasuries and US land and US companies. So, why would China do this? Here is the situation stable yuan US trade deficit D US $ Market _______ S $40 P $30 P2 $20 The US runs a trade deficit at the existing $10 exchange rate, which should push the US $ $0 lower.

We have not quite gotten to the US of E, but a number of European countries did adopt a common currency – the euro – that has been in the news a lot since the financial crisis. In the diagrams that follow you can see the growth of the European Union that allows pretty free movement between these countries and the subset of those countries that have adopted the euro. You also see the slide of unrest in Greece, a country that was running a trade deficit that needed to be closed.

Europe’s 21st century: US of E? EU European Union Euro Common currency Greece Greece was running a trade deficit, so what were its options – and why did they choose one that ended up with scenes like the one above? Greece’s Options We know from our earlier work that Greece had three options because of the trilemma 1.Simply stop the flow of currency – could not do this while on the euro 2.Devalue its currency – could not do this while on the euro 3.Strangle its economy to reduce imports and increase exports – the only option if it stayed on the euro – and you can see the results. England’s Suez Moment Greece’s problem looks very much like England’s Suez moment America’s Suez Moment? Will the US suffer its own moment?
