CHAPTER 34: Open-Economy Macroeconomics: The Balance Open-Economy Macroeconomics:
The Balance of Payments and Exchange Rates

When people in different countries buy from and sell to each other, an exchange of
currencies must also take place.

exchange rate The price of one
country’s currency in terms of
another country’s currency; the
ratio at which two currencies are
traded for each other.



THE BALANCE OF PAYMENTS

foreign exchange All currencies
other than the domestic currency
of a given country.

balance of payments The
record of a country’s
transactions in goods, services,
and assets with the rest of the
world; also the record of a
country’s sources (supply) and
uses (demand) of foreign
exchange.




THE CURRENT ACCOUNT

balance of trade A country’s
exports of goods and services
minus its imports of goods and
services.

THE CURRENT ACCOUNT

trade deficit Occurs when a
country’s exports of goods and
services are less than its imports
of goods and services in a given
period.
balance on current account
Net exports of goods, plus net
exports of services, plus net
investment income, plus net
transfer payments.




THE CAPITAL ACCOUNT

balance on capital account In
the United States, the sum of the
following (measured in a given
period): the change in private U.S.
assets abroad, the change in
foreign private assets in the
United States, the change in U.S.
government assets abroad, and
the change in foreign government
assets in the United States.




THE UNITED STATES AS A DEBTOR NATION

Prior to the mid-1970s, the United States had
generally run current account surpluses. This
began to turn around in the mid-1970s, and by
the mid-1980s, the United States was running
large current account deficits. In other words,
the United States changed from a creditor
nation to a debtor nation.


CHAPTER 34: Open-Economy Macroeconomics: The Balance EQUILIBRIUM OUTPUT (INCOME)
IN AN OPEN ECONOMY
THE INTERNATIONAL SECTOR AND PLANNED
AGGREGATE EXPENDITURE

Planned aggregate expenditure in an open economy:
AE C + I + G + EX - IM

net exports of goods and
services (EX - IM) The
difference between a country’s
total exports and total imports.

Determining the Level of Imports
marginal propensity to
import (MPM) The change in
imports caused by a $1
change in income.

FIGURE 21.1 Determining Equilibrium Output in an Open Economy


IN AN OPEN ECONOMY

The Open-Economy Multiplier

1
open-economy multiplier
1 ( MPC MPM )

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.


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,


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.


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.

CHAPTER 34: Open-Economy Macroeconomics: The Balance THE OPEN ECONOMY WITH FLEXIBLE
EXCHANGE RATES

THE MARKET FOR FOREIGN EXCHANGE

TABLE 21.2 Some Private Buyers and Sellers in International Exchange
Markets: United States and Great Britain
THE DEMAND FOR POUNDS (SUPPLY OF DOLLARS)
1.Firms, households, or governments that import British goods into the United States or wish to buy
British-made goods and services
2.U.S. citizens traveling in Great Britain
3.Holders of dollars who want to buy British stocks, bonds, or other financial instruments
4.U.S. companies that want to invest in Great Britain
5.Speculators who anticipate a decline in the value of the dollar relative to the pound

THE SUPPLY OF POUNDS (DEMAND FOR DOLLARS)
1. Firms, households, or governments that import U.S. goods into Great Britain or wish to buy U.S.-
made goods and services
2. British citizens traveling in the United States
3. Holders of pounds who want to buy stocks, bonds, or other financial instruments in the United
States
4. British companies that want to invest in the United States
5. Speculators who anticipate a rise in the value of the dollar relative to the pound


EXCHANGE RATES

floating, or market-determined, exchange rates

Exchange rates that are determined by the
unregulated forces of supply and demand.

in the Foreign Exchange Market the Foreign Exchange Market


EXCHANGE RATES

The Equilibrium Exchange Rate

The equilibrium exchange rate occurs at the point at which the quantity demanded of
a foreign currency equals the quantity of that currency supplied.

appreciation of a
currency The rise in value
of one currency relative to
another.
depreciation of a
currency The fall in value
of one currency relative to
FIGURE 21.4 The Equilibrium Exchange Rate another.

EXCHANGE RATES
FACTORS THAT AFFECT EXCHANGE RATES

Purchasing Power Parity: The Law of One Price
law of one price If the costs of
transportation are small, the price of the
same good in different countries should be
roughly the same.
purchasing-power-parity theory A
theory of international exchange holding
that exchange rates are set so that the
price of similar goods in different countries
is the same.
A high rate of inflation in one country relative to another puts pressure on the exchange
rate between the two countries, and there is a general tendency for the currencies of
relatively high-inflation countries to depreciate.

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.

Exchange Rate Effects on Imports, Exports, and
Real GDP
A depreciation of a country’s currency is likely to increase its GDP.


EXCHANGE RATES

Exchange Rates and Prices The depreciation of a

country’s currency tends to increase its price level.

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.

Monetary Policy with Fixed Exchange Rates
There is no role monetary policy can play if a country has a
fixed exchange rate.



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.
