Md/P = 640 + 0.1Y -5000 (r + πe). Suppose the central bank changes the nominal money supply depending on income and inflation: Ms = 1000 + 0.1Y -4000π.

(a) If expected inflation equals actual inflation = 0.03, Y = 1000, and r = 0.02, calculate the price level.

(b) If inflation rises to0.04 while the other variables remain as in part a, calculate the price level.

(c) If expected inflation rises to 0.04 while the other variables remain as in part a, calculate the price level.

(d) If the real interest rate rises to 0.03 while the other variables remain as in part a, calculate the price level.

    5. Suppose that instead of following the interest rate rule r=r(Y), the central bank keeps the money supply constant. That is, suppose M = M. In addition, suppose that prices are completely rigid, so that the nominal and the real interest rate are necessarily equal; money-market equilibrium is therefore given by M/= = L(r,Y). a. Suppose that the money market is in equilibrium when r = ro and Yo. Now suppose Y rises to Y). For the money market to...
