3. Long-run exchange rate model (based on PPP)

(a) Write down the fundamental equation of the monetary approach to the exchange rate.

(b) Using the above equation explain how a change in domestic interest rate affects the long-run level of exchange rate. Compare the prediction of this model with prediction of the interest rate parity.

(c) Explain what is the Fisher effect. Write down the mathematical formula on which this effect is based.

(d) Explain how Fisher effect allows us to reconcile the monetarist approach to the exchange rate with the approach based on the interest rate parity.

Suppose that a monetary model describes the long-run behavior of the nominal exchange rate well, but fails to describe the short-run behavior; specifically, in the short run large deviations from purchasing power parity are observed due to nominal rigidities in goods’ prices and overshooting of the nominal exchange rate in response to monetary shocks occurs as a result. a) What are the three key modeling assumptions used to derive the monetary model of exchange rates? What is the only one...
