Answer: The three factors that affect the demand for foreign currency are expected return, risk and liquidity.

Page Ref: 352-361

Difficulty: Easy
12) Explain risk and liquidity of assets.

Answer: Risk is the variability an asset contributes to a savers' wealth. An asset's real return can be unpredictable and savers dislike this uncertainty if the return fluctuates widely. Liquidity refers to the ease with which an asset can be sold or exchanged for goods. Cash is the most liquid of assets because it is always acceptable at face value as payment for goods or other assets. Thus, savers consider an asset's liquidity and its expected return and risk in deciding how much of it to hold.

Answer: B

Page Ref: 361-365

Difficulty: Easy

3) What is the interest parity condition?

Answer: The condition that the expected returns on deposits of any two currencies are equal when measured in the same currency is called the interest parity condition. It implies that potential holders of foreign currency deposits view them as equally desirable assets, i.e. risk is assumed away.

In notational forms:

R_$ = R_E + ( - E_$/E)/E_$/E

Page Ref: 361-365

Difficulty: Easy

4) Explain why the interest parity condition must hold if the foreign exchange market is in equilibrium.

Answer: The foreign exchange market is in equilibrium when deposits of all currencies offer the same expected rate of return. Potential holders of foreign currency deposits view them all as equally desirable assets. If expected rate of return on any currency deposit is higher or lower than the other, there will exist an excess supply or demand for that currency because one will yield a higher return than the other.

B) For a fixed interest rate, a rise in the expected future exchange rate causes a fall in the current exchange rate.

C) For a fixed interest rate, a rise in the expected future exchange rate does not cause a change in the current exchange rate.

D) For a given dollar interest rate and a constant expected exchange rate, a rise in the interest rate of the euro causes the dollar to depreciate.

E) For a fixed interest rate, a fall in the expected future exchange rate causes a rise in the current exchange rate.

3) Discuss the effects of a rise in the dollar interest rate on the exchange rate.

Answer: There are two effects to consider. A rise in the interest rate offered by dollar deposits combined with a constant expected exchange rate will cause the dollar to appreciate (see Figure 14-5 from the text). However, the expected exchange rate will likely change. As Figure 14-6 from the text shows, if the expected exchange rate increases, the dollar will depreciate.

4) Discuss the effects of a rise in the interest rate paid by euro deposits on the exchange rate.

Answer: There are two effects to consider. If we make the unrealistic assumption that the expected exchange rate will not change, then a rise in the interest rate paid by Euro deposits causes the dollar to depreciate. However, if the expected exchange rate were to rise, then the current exchange rate would also rise. (See Figure 14-6 from the text.)

5) Explain why (holding interest rates constant), a rise in the expected depreciation in a country's currency leads to depreciation of that currency today.

Answer: A rise in the expected depreciation rate of the dollar raises the expected dollar return on euro deposits. Now, there are excess supply of dollar deposits (euro deposits offer higher expected rate of return than do dollar deposits). The dollar must depreciate to remove this excess supply.

6) Show graphically a drop in the interest rate paid by euro deposits. What is the effect on the dollar?

Answer: A drop in the interest rate from R1$ to R2$ causes the dollar to depreciate from (point 2) to (point 1). (See Figure 14-5 from the text.)

Answer: A drop in the interest rate paid by euro deposits causes the dollar to appreciate from (point 2) to (point 1). The expected future exchange rate also drops. (See Figure 14-6 from the text.)
