Chapter 21 The Balance of Payments, Exchange Rates, and Trade Deficits
QUESTIONS
1. Do all international financial transactions necessarily involve exchanging one nation’s distinct
currency for another? Explain. Could a nation that neither imports goods and services nor exports
goods and services still engage in international financial transactions? LO1
Answer: The answer is almost certainly a yes. Only in rare cases would you find barter
2. Explain: “U.S. exports earn supplies of foreign currencies that Americans can use to finance
imports.” Indicate whether each of the following creates a demand for or a supply of European
euros in foreign exchange markets: LO1
a. A U.S. airline firm purchases several Airbus planes assembled in France.
b. A German automobile firm decides to build an assembly plant in South Carolina.
c. A U.S. college student decides to spend a year studying at the Sorbonne in Paris.
d. An Italian manufacturer ships machinery from one Italian port to another on a Liberian
freighter.
e. The U.S. economy grows faster than the French economy.
f. A U.S. government bond held by a Spanish citizen matures, and the loan amount is paid back to
that person.
g. It is widely expected that the euro will depreciate in the near future.
Answer: American exports lead to an increase in the foreign-currency bank deposit
holdings of Americans. These holdings will be decreased through American purchases of
imports. Hence, the foreign-currency assets earned through exports can be used to

3. What do the plus signs and negative signs signify in the U.S. balance of payments statement?
Which of the following items appear in the current account and which appear in the capital and
financial account? U.S. purchases of assets abroad; U.S. services imports; foreign purchases of
assets in the United States; U.S. good exports, U.S. net investment income. Why must the current
account and the capital and financial account sum to zero? LO2
Answer: The plus sign (+) indicates a credit to the U.S. balance of payments. The
negative sign (-) indicates a debit the U.S balance of payments.
4. What are official reserves? How do net sales of official reserves to foreigners and net
purchases of official reserves from foreigners relate to U.S. balance-of-payment deficits and
surpluses? Explain why these deficits and surpluses are not actual deficits and surpluses in the
overall balance of payments statement. LO2
Answer: Official reserves consist of foreign currencies, certain reserves held with the
International Monetary Fund, and stocks of gold. These reserves are owned by
governments or their central banks.

5. Generally speaking, how is the dollar price of euros determined? Cite a factor that might
increase the dollar price of euros. Cite a different factor that might decrease the dollar price of
euros. Explain: “A rise in the dollar price of euros necessarily means a fall in the euro price of
dollars.” Illustrate and elaborate: “The dollar-euro exchange rate provides a direct link between
the prices of goods and services produced in the Euro Zone and in the United States.” Explain the
purchasing-power-parity theory of exchange rates, using the euro-dollar exchange rate as an
illustration. LO3
Answer: The dollar price of the euro is determined in a currency exchange market that
equates the supply of euros with the demand for euros.
A factor that might increase the dollar price of the euro could be the result of an increase
6. Suppose that a Swiss watchmaker imports watch components from Sweden and exports
watches to the United States. Also suppose the dollar depreciates, and the Swedish krona
appreciates, relative to the Swiss franc. Speculate as to how each would hurt the Swiss
watchmaker. LO3

21-4
Answer: If the dollar depreciated relative to the franc, this means that it took more
dollars to get the francs necessary to buy a watch. In other words, the watch becomes
7. Explain why the U.S. demand for Mexican pesos is downsloping and the supply of pesos to
Americans is upsloping. Assuming a system of flexible exchange rates between Mexico and the
United States, indicate whether each of the following would cause the Mexican peso to appreciate
or depreciate, other things equal: LO3
a. The United States unilaterally reduces tariffs on Mexican products.
b. Mexico encounters severe inflation.
c. Deteriorating political relations reduce American tourism in Mexico.
d. The U.S. economy moves into a severe recession.
e. The United States engages in a high-interest-rate monetary policy.
f. Mexican products become more fashionable to U.S. consumers.
g. The Mexican government encourages U.S. firms to invest in Mexican oil fields.
h. The rate of productivity growth in the United States diminishes sharply.
Answer: The U.S. demand for pesos is downward-sloping: When the peso depreciates in
value (relative to the dollar) the United States finds that Mexican goods and services are
less expensive in dollar terms and purchases more of them, demanding a greater quantity

8. Explain why you agree or disagree with the following statements: LO3
a. A country that grows faster than its major trading partners can expect the international value of
its currency to depreciate.
b. A nation whose interest rate is rising more rapidly than interest rates in other nations can
expect the international value of its currency to appreciate.
c. A country’s currency will appreciate if its inflation rate is less than that of the rest of the world.
Answer:
(a) This statement is true. If high rates of economic growth mean that the real incomes
of a country’s citizens are rising more rapidly than in other countries, its imports will
rise more than its exports. The demand for foreign currency by its citizens will
9. “Exports pay for imports. Yet in 2009 the nations of the world exported about $379 billion
more of goods and services to the United States than they imported from the United States.”
Resolve the apparent inconsistency of these two statements. LO2
Answer: Exports pay for imports in the long run. In the short term, a country can import
more goods and services than it exports through external borrowing or the sale of
10. Diagram a market in which the equilibrium dollar price of 1 unit of fictitious currency zee (Z)
is $5 (the exchange rate is $5 =Z1). Then show on your diagram a decline in the demand for zee.
LO4
a. Referring to your diagram, discuss the adjustment options the United States would have in
maintaining the exchange rate at $5 = Z1 under a fixed-exchange-rate system.
b. How would the U.S. balance-of-payments surplus that is caused by the decline in demand be
resolved under a system of flexible exchange rates?

Answer: See the graph illustrating the market for zees.
11. Suppose that a country follows a managed-float policy but that its exchange rate is currently
floating freely. In addition, suppose that it has a massive current account deficit. Does it also
necessarily have a balance-of -payments deficit? If it decides to engage in a currency intervention
to reduce the size of its current account deficit, will it buy or sell its own currency? As it does so,
will its official reserves of foreign currencies get larger or smaller? Would that outcome indicate
a balance-of-payments deficit or a balance-of- payments surplus? LO4
Chapter 21 - The Balance of Payments, Exchange Rates, and Trade Deficits
21-7
Answer: No, if the exchange rate is floating freely this market is adjusting to bring the
balance of payments into balance-no need for intervention (the current account deficit is
12. What have been the major causes of the large U.S. trade deficits in recent years? What are the
major benefits and costs associated with trade deficits? Explain: “A trade deficit means that a
nation is receiving more goods and services from abroad than it is sending abroad.” How can that
considered to be “unfavorable”? LO5
Answer:
(1) The U.S. economy has grown more rapidly than the economies of several major
trading nations. Thus U.S. exports have not kept pace with the rise in U.S. imports. (2)
Large trade deficits with China have contributed, with incomes in China too low to result
13. LAST WORD Suppose Super D’Hiver—a hypothetical French snowboard retailer—wants to
order 5000 snowboards made in the United States. The price per board is $200, the present
exchange rate is 1 euro = $1, and payment is due in dollars when the boards are delivered in 3
months. Use a numerical example to explain why exchange-rate risk might make the French
retailer hesitant to place the order. How might speculators absorb some of Super D’Hiver’s risk?
Chapter 21 - The Balance of Payments, Exchange Rates, and Trade Deficits
21-8
Answer: Because payment is due in three months in dollars, the French retailer might
worry that his anticipated price, which today is 1 million euros (5,000 boards at $200
when the exchange rate is 1 euro per dollar), might rise if the euro loses value relative to
