True or False Questions

1

1)

1

Asset approach models to exchange rate determination put more emphasis on financial assets rather than relying on international trade in goods to explain exchange rate changes. Therefore, there is no useful role for trade flows in these models.

False

Explanation:

None Given

2)

1

Currency substitution between monies makes it easier for central banks to follow an independent monetary policy under flexible exchange rates since the currency substitution leads to less volatile exchange rates.

Essay Questions

1)

1

What are the similarities and differences between the "monetary approach" and the "portfolio-balance approach." Briefly explain.

1

Answer:

1

Both approaches emphasize trade in financial assets in determining the exchange rate, both assume perfect capital mobility. Monetary approach models assume perfect substitutability between domestic and foreign assets while portfolio balance models assume imperfect substitutability.

2)

1

Suppose, under fixed exchange rates, you find evidence of sterilization. What does it mean regarding the ability of central banks to follow independent monetary policies? What does sterilization imply regarding the causality between domestic credit and reserve flows under fixed exchange rates?

1

Answer:

1

Sterilization will permit central banks to offset the effects of international reserve flows on the domestic money supply, at least in the short run. This will allow independent monetary policy. Causality is then two-way. R affects D for sterilization, but D affects R through monetary approach effects.

3)

1

What is the role of "trade flows" in the modern asset market approach to exchange rate determination? Suppose you are expecting a future U.S. trade deficit, how does this affect the dollar today?

1

Answer:

1

Since trade flows are matched by financial asset flows, trade flows will be reflected in changing asset holdings. The dollar would depreciate on news of a larger U.S. trade deficit since U.S. net holdings of foreign assets would fall.

4)

1

Explain how exchange rates can overshoot their long-run equilibrium level.

1

Answer:

1

If money demand depends on Y and i, and P and Y are slow to adjust, then i will take initial adjustment to a change in money supply. To maintain IRP, as i changes, the forward premium changes, but E changes by more than F. So E overshoots F, the long-run value of E.

5)

1

How does currency substitution between monies affect the ability of central banks to follow independent monetary policies under flexible exchange rates? Briefly discuss.

1

Answer:

1

Currency substitution will lead to portfolio adjustments between high-inflation and low-inflation monies. A central bank that followed an inflationary policy would find the demand for its money would fall to zero if a perfect substitute existed that had a stable value.

Understanding the foreign exchange market microstructure allows us to explain the evolution of the foreign exchange market in an intradaily sense, in which foreign exchange traders adjust their quotes throughout the business day in the absence of any macro news. Define the following two market microstructure terms:

(a) Inventory control effect.

(b) Asymmetric information effect. Why are they relevant?

1

Answer:

1

(a) Inventory control effect: basically says that traders will want to have no inventory at the end of the day, so that their quotes reflect this desire.

(b) Asymmetric information effect: traders fear that they can be trading with agents who have better information than themselves, so every trade they make, they gain information about where the market is going. Both of these effects can help explain why exchange rates change throughout the day, even in the absence of news regarding the fundamental determinants of exchange rates.
