1 Macroeconomic Policy Objectives Internal balance Full employment…maximum output Stable prices –“Overemployment”  rising prices –Less-than-full-employment  falling prices –Volatile aggregate demand and output lead to volatile prices. –Price level volatility  uncertainty  inefficiency External balance: Current account –not so much in deficit to be unable to repay foreign debt –not so much in surplus that foreigners can’t repay their debts

2 Achieving Internal and External Balance Pegged rates  Fiscal policy effective  Exchange rate can be changed –Devaluation/revaluation  Tools: Expenditure changing: fiscal policy Expenditure switching: exchange rate setting –Need as many tools as you have objectives  For external balance, XX –G up  Y up  CA down … unless E up (devaluation)  For internal balance, II –E down (revaluation)  CA down  Y down … unless G up

3 Internal Balance (II), External Balance (XX)  “Four Zones of Economic Discomfort”

4 The Open-Economy Trilemma The Impossible Trilogy  Impossible for a country to achieve more than two items from the following list: 1. Exchange rate stability…fixed (or managed) rates 2. Monetary policy for internal balance. 3. Freedom of international capital movements.

5 The Policy Trilemma for Open Economies

6 Macroeconomic Policy Under the Classical Gold Standard: 1870–1914  Mechanisms keeping official gold flows (the balance of payments) from becoming too positive or too negative. Gold stock  Money supply  Price level  Current account Hume’s Specie Flow Mechanism Gold stock  Money supply  Output&income  Current account Gold stock  Money supply  Interest rate  Capital flows Central banks management of bank rate –Keep private capital flows ≈ Current account “Rules of the game” not followed Gold stock  Financial influence  Sterilize gold inflows Central bank cooperation –Lending to keep gold stocks stable

7 The Gold Standard and Internal Balance The US economy, 1873 – 1913 –Deflation –Frequent financial crises –Frequent recessions –1890 – 1913 unemployment: 6.8% on average –1946 – 1992 unemployment: 5.7% on average

8 WW I: Capital flight  breakdown of gold standard  Interwar turbulence –Legacies of WW I –Redrawn borders  disrupted trade patterns –Overhang of “Old Debts”: »reparations/inter-allied loans – Labor empowered: The eight hour day Excessive claims  hyperinflation  Gold Standard Nostalgia Restore London dominance

9 $ Dominance/New York Dominance  Classical gold standard, 1870 – 1914 £ dominant despite US economic prowess –US banks couldn’t branch overseas –Bimetalism and its legacy  $ looked risky  WW I  £ instability  $ denominated transactions w/Latin America, Asia –Federal Reserve fostered market in int’l acceptances –Benjamin Strong and his legacy –Post-war credit in $s –European government bonds denominated in $s –National City Bank/Others/Branching Abroad  US financial dominance: from mid-1920s International economy disrupted in depression, WWII

10 ‘20s Halting return to gold  Prelude to depression –The Economic Consequences of Mr. Churchill  General Strike –US monetary expansion – help to Britain  Roaring ’20s –Capital flow reversal  European downturn –B u b b l e and c o l l a p s e ‘30s World in Depression: Who Leads? UK couldn’t …US wouldn’t  Protection … beggar thy neighbor 1931 European banking crises and contagion –Creditanstalt  German banks  British investment banks  Flight from the £ September 1931: Britain leaves gold – US defends gold standard  Crisis and the Great Depression Golden fetters –Halting recovery: monetary expansion/fiscal measures/rearmament

11 Postwar: Restore Stability  Bretton Woods System  IMF a bank/World Bank a fund  $ pegged to gold … N – 1 currencies pegged to an elastic $  IMF: International lender of last resort support pegs allow devaluation when fundamental disequilibrium  Capital controls on international financial transactions Protect financial account/Prevent balance of payments crisis  Currencies were convertible to encourage trade in goods and services  Fiscal policy the principal tool for internal balance  Principal tools for external balance borrowing from the IMF restrictions on financial asset flows infrequent changes in exchange rates.

12 Policy Mix for Internal and External Balance: 2 Goals – 2 Tools Starting with CA Deficit and Underemployment  Fiscal stimulus + Devaluation Under the fixed exchange rates of the Bretton Woods system, devaluations were supposed to be infrequent – fiscal policy was supposed to be the main policy tool to achieve both internal and external balance. In general, fiscal policy cannot attain both internal balance and external balance at the same time. A devaluation, however, can move toward both internal balance and external balance at the same time. Speculator anticipation of devaluation  greater internal or external imbalances.

13 Bretton Woods: $ Standard…more flexible than gold  Each central bank fixed the dollar exchange rate of its currency through foreign exchange market trades for $s Exchange rates between any two currencies fixed by arbitrage.  The US could use M-policy for macroeconomic stabilization despite fixed rates. Purchase of domestic assets by the Federal Reserve leads to –Excess US demand for foreign currencies in the foreign exchange market –Purchases of $s by foreign central banks to keep $ from depreciating Expansionary monetary policies by all other central banks –Higher world output … and/or INFLATION Reserve Currencies in Int’l Monetary System

14 Bretton Woods System Problems/breakdown: –Speculative attacks against weak currencies –Gold & $ Shortage Buildup of $ reserves > US gold stock –$ Glut Vietnam era expansion  Pus up  overvalued $  Rush out of $s…try to redeem gold the US doesn’t have –Nixon Economic Program, August 15, 1971 –Close gold window…8% devaluation against gold in 12/71 –Import surcharge –Wage/price controls –1973 Collapse of Bretton Woods system –Foreign central banks refused to buy overvalued $ assets

15 Exporting US Inflation: 1966–1972

16 Effect on Internal and External Balance of a Rise in the Foreign (US) Price Level, P* The “simple” solution for the £, DM, ¥, FF, … Revalue against the $

17 The Case for Floating Exchange Rates Monetary policy autonomy…w/o capital controls –Each country can choose “appropriate” long-run inflation rate Symmetry –$ can “devalue” as necessary…not constrained as leader –Other countries can use monetary tool Exchange rates as automatic stabilizers –Floating cushions output against real shocks –Something’s gotta adjust…if not E, then Y –Depreciation in the face of reduced demand for a nation’s exports restores equilibrium automatically –Unlike Bretton Woods »there would be a “fundamental disequilibrium” »and ongoing CA deficit and loss of reserves »until price level fell or currency devalued

18 AA 1 DD 1 Effects of a Temporary Fall in Export Demand AA 2 DD 2 AA 1 DD 2 DD 1 E2E2 2 Y2Y2 Y2Y2 Output, Y Exchange rate, E (a) Floating exchange rate Output, Y Exchange rate, E (b) Fixed exchange rate Y1Y1 E1E1 1 Y1Y1 E 1 1 Y3Y3 3 The Case for Floating Exchange Rates Depreciation leads to higher demand for and output of domestic products Fixed exchange rates mean output falls as much as the initial fall in aggregate demand

19 The Case Against Floating Exchange Rates  Lack of discipline … but a floating exchange rate bottles up inflation in a country whose government is “misbehaving”.  Destabilizing speculation Hot money …but “fundamental disequilibrium”  one-way bet under fixed rates Countries can be caught in a “vicious circle” of depreciation and inflation. E deprec  P im up  CoL up  W up  P up  E deprec Floating exchange rates make a country more vulnerable to money market disturbances: L up  R up  E-apprec.  CA & Y down –Fixed rates cushion output against monetary shocks L up  M up  nothing shifts under fixed rates

20 AA 1 DD Output, Y Exchange rate, E E1E1 Y1Y1 1 A Rise in Money Demand Under a Floating Exchange Rate AA 2 E2E2 Y2Y2 2 The Case Against Floating Exchange Rates

21 What really matters?  Recall: With fixed rate, monetary policy is ineffective (given free capital flows) –Similarly, monetary shocks have no real effect With floating rates, fiscal policy is ineffective –Similarly, temporary real shocks [like drop in demand for exports] have little real effect –Permanent real shocks have “no” real effects

22  Injury to International Trade and Investment Exporters and importers face greater exchange risk. –But forward markets can protect traders against foreign exchange risk. International investments face greater uncertainty about payoffs denominated in home country currency.  Uncoordinated Economic Policies Countries can engage in competitive currency depreciations. …under Bretton Woods, policies “coordinated” via US privilege A large country’s fiscal and monetary policies affect other economies …aggregate demand, output, and prices become more volatile across countries if policies diverge.  Free Float Really Managed Float Fear of depreciation – inflation spiral  intervention The Case Against Floating Exchange Rates

23 Speculation and volatility in the foreign exchange market If traders expect a currency to depreciate in the short run, they may quickly sell the currency to make a profit, even if it is not expected to depreciate in the long run. Expectations of depreciation lead to actual depreciation in the short run. The assumption we’ve been using that expectations do not change when temporary economic changes occur is not valid if expectations change quickly in anticipation of even temporary economic changes. In fact, exchange rate volatility has increased since 1973

27  Due to contractionary monetary policy (Volcker disinflation) and expansive fiscal policy (Reagan tax cut and military buildup, the $ appreciated by about 50% relative to 15 currencies from 1980–1985.  growing US CA deficit & rest-of-world capital shortage  Major efforts to influence exchange rates: The 1985 Plaza Accord reduced the value of the dollar relative to other major currencies… “bringing down dollar” The 1987 Louvre Accord: intended to stabilize exchange rates –Specified zones of +/- 5% around which current exchange rates were allowed to fluctuate. –Quickly abandoned –The October 1987 stock market crash made production, employment and price stability the primary goals for the U.S. »Did tightening to support $ trigger “Black Monday”? »After Black Monday, exchange rate stability became less important. –New targets were (secretly) made after October 1987, but central banks had abandoned these targets by the early 1990s.

28 Macroeconomic Interdependence Under Floating Rate The Large Country Case Effect of a permanent monetary expansion by US –$ depreciates, US output rises –Foreign output may rise or fall. –Foreign’s currency appreciates  Foreign’s output falls –US economy expands  Foreign sells more to US Effect of a permanent fiscal expansion by US –US output rises, US currency appreciates –Foreign output rises –Foreign’s currency depreciates  Foreign’s output rises –US economy expands  Foreign sells more to US Large Country => Locomotive

29 Exchange Rate Trends and Inflation Differentials, 1973–2009 Source: International Monetary Fund and Global Financial Data. High-inflation countries have tended to have weaker currencies than their low-inflation neighbors.

30 Global External Imbalances, 1999–2009 Source: International Monetary Fund, World Economic Outlook database. The U.S. has run a current account deficit for many years due to its low saving and high investment expenditure. Rebalancing: As foreign countries spend more and lend less to the U.S., interest rates may rise the U.S. dollar will depreciating the U.S. current account will improve (becoming less negative).

33 After 1973 central banks intervened repeatedly in the foreign exchange market to alter currency values. –To stabilize output and the price level when certain disturbances occur –To prevent sharp changes in the international competitiveness of tradable goods sectors Monetary changes had a much greater short-run effect on the real exchange rate under a floating nominal exchange rate than under a fixed one. The international monetary system did not become symmetric until after –Central banks continued to hold dollar reserves and intervene. The current floating-rate system is similar in some ways to the asymmetric reserve currency system underlying the Bretton Woods arrangements … exorbitant privilege What Has Been Learned Since 1973?

34  The Exchange Rate as an Automatic Stabilizer Experience with the oil shocks of 1973 and 1979 favors floating exchange rates. The effects of the U.S. fiscal expansion after 1981 provide mixed evidence on the success of floating exchange rates.  Discipline Inflation rates accelerated after 1973 and remained high through the second oil shock. The system placed fewer obvious restraints on unbalanced fiscal policies. –Example: The high U.S. government budget deficits of the 1980s. What Has Been Learned Since 1973?

35  Destabilizing Speculation Floating exchange rates have exhibited much more day-to- day volatility. –The question of whether exchange rate volatility has been excessive is controversial. In the longer term, exchange rates have roughly reflected fundamental changes in monetary and fiscal policies and not destabilizing speculation. Experience with floating exchange rates contradicts the idea that arbitrary exchange rate movements can lead to “vicious circles” of inflation and depreciation.  International Trade and Investment For most countries, the extent of their international trade shows a rising trend after the move to floating. What Has Been Learned Since 1973?

36  Many fixed exchange rate systems have developed since European monetary system and euro zone The Chinese central bank currently fixes the value of its currency. ASEAN countries have considered a fixed exchange rates and policy coordination.
