2.) Assume that the Long Run Aggregate Supply curve is Y = 10000; The Aggregate Demand curve is Y = 5(M/P); Prices are fixed at 1.5 and M = 3000. a.) If the economy is initially in long-run equilibrium, what are the values of P and Y? b.) Now suppose a supply shock causes the short-run aggregate supply to shift to 2. What are the new short-run P and Y? c.) If the aggregate demand curve and long-run aggregate supply curve are unchanged, what are the long-run equilibrium P and Y after the supply shock? d.) Suppose that after the supply shock the Fed wanted to hold output at its long-run level. What level of M would be required? If this level of M were maintained, what would be long-run equilibrium P and Y?
