Chapter 15: Flexible Exchange Rates
MULTIPLE CHOICE
1. In the trade-based model of exchange rate determination, the nominal exchange rate is
determined by:
a. Purchases and sales of currencies arising from imports and exports.
b. Transactions arising from the exchange of assets.
c. Transactions arising from both the current and capital/financial accounts of the
balance of payments.
d. None of the above.
2. In the assets-based model of exchange rate determination, the nominal exchange rate is
determined by:
a. Purchases and sales of currencies arising from imports and exports.
b. Transactions arising from the exchange of assets.
c. Transactions arising from both the current and capital/financial accounts of the
balance of payments.
d. All of the above.
3. In the trade-based model of exchange rate determination as developed in this book, the
demand for the home-country currency is assumed to be:
a. Perfectly inelastic.
b. Relatively inelastic.
c. Relatively elastic.
d. None of the above.
4. In the trade-based model of exchange rate determination for a flexible exchange rate
regime, how is the equilibrium exchange rate determined?
a. When the supply of a country’s currency exceeds demand.
b. When the supply of a country’s currency is less than demand.
c. When the supply of a country’s currency is equal to the amount demanded.
d. None of the above.
5. In the trade-based model of exchange rate determination for a flexible exchange rate
regime, suppose that the supply of a country’s currency exceeds demand for it. What
must happen to achieve an equilibrium exchange rate?
a. The excess supply of the currency will act to reduce demand for it.
b. As the currency depreciates, the trade deficit falls.
c. The trade deficit falls until the nominal exchange rate reaches a value where the
supply of the currency equals the demand for it.
d. All of the above.
6. In an assets-based model of exchange rate determination for a flexible exchange rate
regime, suppose that the supply of a county’s currency exceeds demand for it. Which of
the following will help to achieve an equilibrium exchange rate?
a. The rise in the value of the currency decreases the trade deficit.
b. The fall in the value of the currency increases the trade deficit.
c. The fall in the value of the currency increases foreign savings.
d. None of the above.
7. After an expansion of money supply in a country, which of the following is true?
a. The value of the currency decreases.
b. The domestic interest rate decreases.
c. The value of the foreign currency increases.
d. All of the above.
8. After a contraction in the money supply in a country, which of the following is true?
a. The value of the domestic currency decreases.
b. The domestic interest rate rises.
c. The value of the foreign currency rises.
d. None of the above.
9. Covered interest rate parity differs from uncovered interest rate parity in the following
way:
a. Instead of the forward nominal exchange rate, covered interest rate parity uses the
expected exchange rate.
b. Instead of the foreign interest rate, covered interest rate parity uses the domestic
interest rate.
c. Instead of the expected nominal exchange rate, covered interest rate parity uses the
forward exchange rate.
d. Instead of the domestic, interest rate, covered interest rate parity uses the foreign
interest rate.
TRUE/FALSE
1. If exports (E) of a country are negatively related to the value of a country’s currency and
imports (Z) are positively related to the value of this currency, then the trade deficit (Z-E)
is positively related to the value of the currency.
2. The purchasing power parity model of exchange rate determination applies to the short
run, while the trade- and assets-based models apply to the long run.
3. As the value of a country’s currency rises, its demand for imports rises.
4. As the value of a country’s currency rises, demand for its exports falls.
5. As the value of a country’s currency falls, demand for its exports falls.
6. As the value of a country’s currency falls, its demand for imports rises.
7. The assets-based model of exchange rate determination focuses on foreign savings and
the trade deficit in determining how equilibrium nominal exchange rates arise.
8. If a country’s domestic interest rate rises, the value of its currency will rise.
9. If a country’s domestic interest rate falls, the value of its currency will rise.
10. If the foreign interest rate rises, the value of the domestic country’s currency will rise.
11. If the foreign interest rate falls, the value of the domestic country’s currency will rise.
SHORT ANSWER

why?

we call increases and decreases of the nominal exchange rate?
