Exchange Rates
• The main difference between an
international transaction and a
domestic transaction concerns
currency exchange.
• International exchange must be
managed in a way that allows each
partner in the transaction to wind up
with his or her own currency.

Exchange Rates
• The exchange rate is 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
• The balance of payments is 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.

are a credit (+) item on the current
account. Imports use up foreign
exchange and are a debit (–) item.

The Current Account
• The balance of trade is the
difference between a country’s
exports of goods and services and
its imports of goods and services.
• A trade deficit occurs when a
country’s exports are less than its
imports.
• Net exports of goods and services
(EX – IM), is the difference between
a country’s total exports and total
imports.

current account, there is an offsetting
transaction recorded in the capital
account.
• The capital account records the
changes in assets and liabilities.

The Capital Account
• The balance on capital account in the
United States is 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 Capital Account
• In the absence of errors, the balance on
capital account would equal the negative
of the balance on current account.
• If the capital account is positive, the
change in foreign assets in the country is
greater than the change in the country’s
assets abroad, which is a decrease in the
net wealth of the country.

The United States as a Debtor Nation
• A country’s net wealth is the sum of
all its past current account balances.
• Prior to the mid-1970s, the United
States was a creditor nation. After
the mid-1970s, the United Sates
began to have a negative net wealth
position vis-à-vis the rest of the
world.

• A negative net wealth position vis-àvis the rest of the world reflects the
fact that the United States spent
much more on foreign goods and
services than it earned through the
sales of its goods and services.

Equilibrium Output (Income)
in an Open Economy
• Exports contribute to an
increase in autonomous
expenditures and cause the
planned aggregate expenditure
function to shift upward.
© 2004 Prentice Hall Business Publishing
• Imports affect the value of the
multiplier. After imports are
included, the aggregate
expenditure function rotates and
equilibrium income decreases.

Imports and Exports and
the Trade Feedback Effect
• The determinants of imports are the
same as the factors that affect
consumption and investment
behavior.
• Spending on imports also depends
on the relative prices of domestically
produced and foreign-produced
goods.

Imports and Exports and
the Trade Feedback Effect
• The demand for U.S. exports
depends on economic activity in the
rest of the world. If foreign output
increases, U.S. exports tend to
increase.
• Because U.S. imports are somebody
else’s exports, the extra import
demand from the United States
raises the exports of the rest of the
world.

• The trade feedback effect is 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.

Imports and Export Prices
and the Trade Feedback Effect
• When the export prices of one
country rise, with no change in the
exchange rate, the import prices of
another rise.
• If the inflation rate abroad is high,
U.S. import prices are likely to rise.

Imports and Export Prices
and the Trade Feedback Effect
• The price feedback effect is the
process by which a domestic price
increase in one country can “feed
back” on itself through export and
import prices.
• Inflation is “exportable.”

The Open Economy with
Flexible Exchange Rates
• Floating, or market-determined,
exchange rates are exchange rates
determined by the unregulated
forces of supply and demand.
• Exchange rate movements have
important impacts on imports,
exports, and movement of capital
between countries.

The Market for Foreign Exchange
• In a world where there are only two
countries, the United States and
Britain, the demand for pounds is
comprised of holders of dollars
wishing to acquire pounds. The
supply of pounds is comprised of
holders of pounds seeking to
exchange them for dollars.

The Market for Foreign Exchange
• The demand for pounds in
the foreign exchange market
shows a negative relationship
between the price of pounds
(dollars per pound) ($/£) and
the quantity of pounds
demanded.
• When the price of pounds falls, British-made goods and services
appear less expensive to U.S. buyers. If British prices are
constant, U.S. buyers will buy more British goods and services,
and the quantity demanded of pounds will rise.

The Market for Foreign Exchange
• The supply of pounds in
the foreign exchange
market shows a positive
relationship between the
price of pounds (dollars per
pound) ($/£) and the
quantity of pounds
supplied.
• When the price of pounds rises, the British can obtain more dollars
for each pound. This means that U.S.-made goods and services
appear less expensive to British buyers. Thus, the quantity of
pounds supplied is likely to rise with the exchange rate.

The Equilibrium Exchange Rate
• An excess supply of pounds will
cause the price of pounds to fall—
the pound will depreciate (fall in
value) with respect to the dollar.
• An excess demand for pounds will
cause the price of pounds to rise—
the pound will appreciate (rise in
value) with respect to the dollar.

Factors that Affect Exchange Rates
• Purchasing Power Parity: The
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.
• If the law of one price held for all goods,
and if each country consumed the same
market basket of goods, the exchange
rate between the two currencies would
be determined simply by the relative
price levels in the two countries.

Factors that Affect Exchange Rates
• The theory that exchange rates are
set so that the price of similar goods
in different countries is the same is
known as the purchasing-power
parity.
• If it takes ten times as many pesos to
buy a pound of salt in Mexico as it takes
U.S. dollars to buy a pound of salt in the
United States, then the equilibrium
exchange rate should be 10 pesos per
dollar.

Factors that Affect Exchange Rates
• 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
relative high-inflation countries to
depreciate.

• A higher price level in
the United States
increases the demand
for pounds and
decreases the supply
of pounds. The result
is appreciation of the
pound against the
dollar.

Factors that Affect Exchange Rates
• The level of a country’s interest rate
relative to interest rates in other
countries is another determinant of
the exchange rate. If U.S. interest
rates rise relative to British interest
rates, British citizens may be
attracted to U.S. securities.

The Effects of Exchange
Rates on the Economy
• When a country’s currency
depreciates (falls in value), its import
prices rise and its export prices (in
foreign currencies) fall.
• When the U.S. dollar is cheap, U.S.
products are more competitive in
world markets, and foreign-made
goods look expensive to U.S.
citizens.

The Effects of Exchange
Rates on the Economy
• A depreciation of a country’s
currency can serve as a stimulus to
the economy:
• Foreign buyers are likely to increase
their spending on U.S. goods
• Buyers substitute U.S.-made goods for
imports
• Aggregate expenditure on domestic
output will rise
• Inventories will fall
• GDP (Y) will increase

Exchange Rates and the
Balance of Trade: The J Curve
• The balance of trade is equal to
export revenue minus import costs:
balance of trade = dollar price of exports x
quantity of exports
 dollar price of imports x quantity of imports
• According to the J-curve effect, the
balance of trade gets worse before it
gets better following a currency
depreciation.

• Initially, the negative effect
on the price of imports may
dominate the positive effects
of an increase in exports
and a decrease in imports.
• But when imports and
exports have had a time to
respond to price changes,
the balance of trade
improves.

Exchange Rates and Prices
• Depreciation of a country’s currency tends
to increase the price level.
• Export demand rises.
• Domestic buyers substitute domestic products
for the now more expensive imports.
• If the economy is operating close to capacity, the
increase in aggregate demand is likely to result
in higher prices.
• If import prices rise, costs may rise for business
firms, shifting the AS curve to the left.

Monetary Policy with
Flexible Exchange Rates
• Fed actions to lower interest rates
result in a decrease in the demand
for dollars and an increase in the
supply of dollars, causing the dollar
to depreciate.
• If the purpose of the Fed is to
stimulate the economy, dollar
depreciation is a good thing. It
increases U.S. exports and
decreases imports.

Fiscal Policy with
Flexible Exchange Rates
• Flexible interest rates may not help
in the attempt by government to cut
taxes in order to stimulate the
economy.
• A tax cut results in increased
household spending, but some of
that spending leaks out as imports,
reducing the multiplier.

Fiscal Policy with
Flexible Exchange Rates
• As income increases, the demand
for money increases. The resulting
higher interest rates cause the dollar
to appreciate. Exports fall, imports
rise, again reducing the multiplier.
• If interest rates rise, private
investment may be crowed out, also
lowering the multiplier.

Monetary Policy with
Fixed Exchange Rates
• Monetary policy has no role in a
country that has a fixed exchange
rate.
• For example, an attempt to lower
interest rates results in currency
depreciation and a lower (not a fixed)
exchange rate.
• In the absence of capital controls,
the monetary authority loses its
independence.

THE GOLD STANDARD
• Early in the century, during the gold
standard era, nearly all currencies were
backed by gold. Their values were
fixed in terms of a specific number of
ounces of gold, which determined their
values in international trading—
exchange rates.

“PURE” FIXED EXCHANGE RATES
• Under this type of system,
governments set a particular fixed rate
at which their currencies will exchange
for each other.
• There is no automatic mechanism to
keep exchange rates aligned with each
other, as with the gold standard.
Therefore, governments must at times
intervene to keep currencies aligned at
their established values.

Market
• If the government has

keeping the value of
the lira at .020, it must
buy up the excess
supply of lira (Qs – Qd).

Appendix: World Monetary
Systems Since 1900
•
At the end of World War II, economists
from the United States and Europe met to
formulate a new set of rules for exchange
rate determination, known as the Bretton
Woods system:
1. Countries were to maintain fixed exchange
rates with each other. All currencies were
fixed in terms of the U.S. dollar.
2. Countries experiencing a persistent current
account deficit (or fundamental disequilibrium)
in their balance of payments were allowed to
change their exchange rates.

• The alternative to a fixed exchange
rate system is a flexible system:
• In a freely floating system,
governments do not intervene at
all in the foreign exchange
market.
• In a managed floating system,
governments intervene if markets
are becoming disorderly.
