CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates THE BALANCE OF PAYMENTS THE UNITED STATES AS A DEBTOR NATION Prior to the mid-1970 s, the United States had generally run current account surpluses. This began to turn around in the mid-1970 s, and by the mid-1980 s, the United States was running large current account deficits. In other words, the United States changed from a creditor nation to a debtor nation. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 17

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates EQUILIBRIUM OUTPUT (INCOME) IN AN OPEN ECONOMY The Open-Economy Multiplier open-economy multiplier The effect of a sustained increase in government spending (or investment) on income— that is, the multiplier—is smaller in an open economy than in a closed economy. The reason: When government spending (or investment) increases and income and consumption rise, some of the extra consumption spending that results is on foreign products and not on domestically produced goods and services. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 20

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates EQUILIBRIUM OUTPUT (INCOME) IN AN OPEN ECONOMY IMPORTS AND EXPORTS AND THE TRADE FEEDBACK EFFECT The Determinants of Imports The same factors that affect households’ consumption behavior and firms’ investment behavior are likely to affect the demand for imports. The Determinants of Exports The demand for U. S. exports depends on economic activity in the rest of the world—rest-of-the-world real wages, wealth, nonlabor income, interest rates, and so on—as well as on the prices of U. S. goods relative to the price of rest-of-the-world goods. If foreign output increases, © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 23

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates EQUILIBRIUM OUTPUT (INCOME) IN AN OPEN ECONOMY The Trade Feedback Effect trade feedback effect The tendency for an increase in the economic activity of one country to lead to a worldwide increase in economic activity, which then feeds back to that country. An increase in U. S. imports increases other countries’ exports, which stimulates those countries’ economies and increases their imports, which increases U. S. exports, which stimulates the U. S. economy and increases its imports, and so on. This is the trade feedback effect. In other words, an increase in U. S. economic activity leads to a worldwide increase in economic activity, which then “feeds back” to the United States. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 24

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates EQUILIBRIUM OUTPUT (INCOME) IN AN OPEN ECONOMY Export prices of other countries affect U. S. import prices. The general rate of inflation abroad is likely to affect U. S. import prices. If the inflation rate abroad is high, U. S. import prices are likely to rise. The Price Feedback Effect price feedback effect The process by which a domestic price increase in one country can “feed back” on itself through export and import prices. An increase in the price level in one country can drive up prices in other countries. This in turn further increases the price level in the first country. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 25

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates THE OPEN ECONOMY WITH FLEXIBLE EXCHANGE RATES THE EFFECTS OF EXCHANGE RATES ON THE ECONOMY The level of imports and exports depends on exchange rates as well as on income and other factors. When events cause exchange rates to adjust, the levels of imports and exports will change. Changes in exports and imports can in turn affect the level of real GDP and the price level. Further, exchange rates themselves also adjust to changes in the economy.

Monetary Policy with Flexible Exchange Rates A cheaper dollar is a good thing if the goal of the monetary expansion is to stimulate the domestic economy. Fiscal Policy with Flexible Exchange Rates The openness of the economy and flexible exchange rates do not always work to the advantage of policy makers.

CHAPTER 21: Open-Economy Macroeconomics: The Balance of Payments and Exchange Rates AN INTERDEPENDENT WORLD ECONOMY The increasing interdependence of countries in the world economy has made the problems facing policy makers more difficult. We used to be able to think of the United States as a relatively self-sufficient region. Forty years ago, economic events outside U. S. borders had relatively little effect on its economy. This situation is no longer true. The events of the past four decades have taught us that the performance of the U. S. economy is heavily dependent on events outside U. S. borders. © 2007 Prentice Hall Business Publishing Principles of Economics 8 e by Case and Fair 47
