Suppose that the economy is initally at a long run equilibrium and that prices are partially sticky. Then the Fed increases the money supply.

a. Assuming any inflation to be unexpected, describe any changes in GDP, unemployment, and inflation that are caused by the monetary expansion. Explain your conclusions using three diagrams: one for the IS-LM model and one for the AD-AS model.

b. Assuming instead that any resulting inflation is expected, describe any changes in GDP, umemployment, and inflation that are caused by the monetary expansion. Once again, explain your conclusions using three diagrams: one for the IS-LM model and one for the AD-AS model.

Suppose the economy is in long-run equilibrium.
Scenario 1 - Pessimism Suppose the economy is in long-run equilibrium.

Suppose the U.S. economy was in both short-run and long-run equilibrium, until the economy experienced inflation. a. Which policy would be consistent with the goals of monetary policy during this time? The Fed repos $25 billion worth of Treasury bonds to non-bank financial firms. The Fed reduces the discount rate from 7 percent to 5 percent. The Fed reduces the reserve ratio from 20 percent to 15 percent. The Fed sells securities worth $100 million to financial institutions.

Consider an economy that begins in long-run equilibrium. Suppose that there is a wave of pessimism that reduces investment demand at any given real interest rate. That is, suppose that the investment demand curve shifts down and to the left. Use the IS-LM diagram and the aggregate supply - aggregate demand diagram to show how this shift down of the investment demand curve affects the interest rate, income, investment, the price level, consumption, and the supply of real money balances...

Be sure to show aggregate demand, short run aggregate supply, and long-run aggregate supply. b. Now suppose that a stock market crash causes aggregate demand to fall.
