Q. In the Cagan model, if the money supply is expected to grow at some constant rate m (so
that Emt+ s = mt + sm), then Equation A9 can be shown to imply that pt = mt + gm.

a. Interpret this result.

b. What happens to the price level pt when the money supply mt changes, holding the money growth rate m constant?

c. What happens to the price level pt when the money growth rate m changes, holding the current money supply mt constant?

d. If a central bank is about to reduce the rate of money growth m but wants to hold the price level pt constant, what should it do with mt? Can you see any practical problems that might arise in following such a policy?

e. How do your previous answers change in the special case where cash demand does not depend on the expected rate of inflation (so that g = 0)?
