The Federal Reserve expands the money supply by 5 percent. a. Use the theory of liquidity preference to illustrate in a graph the impact of this policy on the interest rate. b. Use the model of aggregate demand and aggregate supply to illustrate the impact of this change in the interest rate on output and the price level in the short run. c. When the economy makes the transition from its short-run equilibrium to its new long-run equilibrium, what will happen to the price level? d.

The Federal Reserve expands the money supply by 5 percent. a. Use the theory of liquidity preference to illustrate in a graph the impact of this policy on the interest rate. b. Use the model of aggregate demand and aggregate supply to illustrate the impact of this change in the interest rate on output and the price level in the short run. c. When the economy makes the transition from its short-run equilibrium to its new long-run equilibrium, what will happen to the price level? d. How will this change in the price level affect the demand for money and the equilibrium interest rate? e. Is this analysis consistent with the proposition that money has real effects in the short run but is neutral in the long run? 2. Suppose the economy is in a long-run equilibrium. a. Draw a diagram to illustrate the state of the economy. 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. Use your diagram to show what happens to output and the price level in the short run. What happens to the unemployment rate? c. Explain what will happen to output and the price level in thelong-run(assuming there is no change in policy). Be sure to illustrate your analysis in a graph. 3. In 1939, with the U.S. economy not yet fully recovered from the Great Depression, President Roosevelt proclaimed that Thanksgiving would fall a week earlier than usual so that the shopping period before Christmas would be longer. Explain what President Roosevelt might have been trying to achieve, using the model of aggregate demand and aggregate supply.
