The exchange rate is determined by demand and supply in the forex (foreign exchange) markets where traders buy and sell currencies. The forex markets are very busy with over $1.5 trillion traded every day.

All rights reserved. 33-8 Exchange Rates The supply of euros (demand for dollars) comes from Europeans who want to use them to buy dollars in order to buy U.S. goods or assets.  The supply of euros is positively sloped because if the value of the euro is high, U.S. goods are cheaper for Europeans. The demand for euros comes from Americans who want to buy European goods or assets.  The demand for euros is negatively sloped because if the dollar price of euros is low, Americans want to buy more European goods because they are cheaper for them.

9. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-9 The Supply and Demand for Euros The equilibrium exchange rate is 1 euro = $1.10 or $1 =.77 euros. If the exchange rate is too high ($1.50) there is a surplus of euros and Europe has a deficit in its balance of payments. If the exchange rate is too low ($1.20) there is a shortage of euros and Europe has a balance of payments surplus. S D QSQS QDQD $1.50 1.30 1.20 Quantity of euros Price of euros (in dollars)

The resulting fluctuations serve no real purpose, and cause problems for international trade and the country’s economy. The government can change the value of its currency with monetary and fiscal policy.

The net effect of fiscal policy is ambiguous because the interest rate effect and the income effect work in opposite directions.

21. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-21 Direct Exchange Rate Intervention To avoid the problems caused by fluctuating exchange rates, governments sometimes intervene to fix exchange rates by buying and selling its currency. If it buys its currency, it can increase its exchange rate. If it sells its currency, its value decreases.

The government is not trying to change the long-run equilibrium, but is trying to keep the exchange rate at that long-run equilibrium. A central issue in exchange rate intervention policy is estimating the long-run equilibrium.

According to PPP, if a basket of goods costs $7 in the U.S. and ¥1000 in Japan, the exchange rate should be $1 = 1000/7 = ¥143.

A nominal exchange rate is the actual exchange rate used when currencies are exchanged. %Δ real exchange rate = %Δ nominal exchange rate – (domestic inflation – foreign inflation)

All rights reserved. 33-26 Alternative Exchange Rate Systems Fixed exchange rate – the government chooses an exchange rate and offers to buy and sell currencies at that rate. Flexible exchange rate – determination of exchange rates is left totally up to the market. Partially flexible exchange rate – the government sometimes buys or sells currencies to influence the exchange rate, while at other times letting private market forces operate.

Disadvantages  If they become unfixed, they create monetary instability.  They force governments to make adjustments to meet international problems.

Disadvantages  They allow speculation to cause large jumps in exchange rates.  They allow government to be flexible in conducting monetary and fiscal policy.

29. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-29 Partially Flexible Exchange Rates Partially flexible exchange rate regimes combine the advantages of both fixed and flexible exchange rates. If policy makers believe there is a fundamental misalignment in a country’s exchange rate, they allow market forces to determine it. If they believe the currency’s value is falling because of speculation, they step in and fix the exchange rate.

32. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-32Summary The balance of payments is made up of the current account and the financial and capital account. Exchange rates in perfectly flexible systems are determined by the supply of and demand for a currency. The following increase demand for foreign currencies and depreciate domestic currencies:  An increase in domestic income  An increase in domestic prices  A decrease in domestic interest rates  A reduction in trade restrictions on imports

33. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-33Summary To raise the value of domestic currency a country can either increase private demand or decrease private supply through contractionary monetary policy. Expansionary monetary policy, through its effect on interest rates, income, and price level, tends to lower a country’s exchange rate. Fiscal policy has an ambiguous effect on a country’s exchange rate.

34. McGraw-Hill/Irwin Copyright  2006 by The McGraw-Hill Companies, Inc. All rights reserved. 33-34Summary A country can stabilize or fix its exchange rate by either directly buying and selling its own currency or adjusting its monetary and fiscal policy to achieve its exchange rate goal. It is easier technically for a country to bring the value of its currency down than it is to support its currency. The purchasing power parity approach can be used to estimate the long-run equilibrium exchange rate.

How will this affect the value of the dollar? If U.S. interest rates increase, demand for U.S. bonds will increase, causing the demand for dollars to increase. If the demand for dollars increases, the exchange rate for the dollar will increase. Review Question 33-2 How does an expansionary monetary policy cause a decrease in exchange rates? An expansionary monetary policy will decrease interest rates and increase incomes and prices. The decrease in interest rates will decrease the demand for the dollar causing its value to fall. The increase in incomes and prices will increase the demand for imports. In order to buy more imports, Americans will increase the supply of dollars to buy foreign currencies, causing a decrease in the exchange rate of the dollar.
