The economy has been given by the following IS-LM curves. What are the consequences of an expansionary monetary policy(for instance, an increase in G) in the short run and in the long run? The FOMC started to taper and nominal interest rate moves lower. What is the rational for that? Please also add the AD-AS analysis to your argument, if necessary
Consider the classical AS-AD model with misperceptions. Assume that the economy is initially at its general equilibrium. Now, suppose the central bank considers an increase in the nominal money supply that is not anticipated by households or firms.
a. How does the misperception theory work?
b. Which of the three markets is first affected (labor, goods, or asset market)? Explain and show graphically how this market is affected by an unanticipated increase in the nominal money supply.
c. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the short-run equilibrium.
d. Use the classical version of the AS-AD model with misperceptions to explain and to show graphically how an unanticipated increase in the nominal money supply affects the long-run (general) equilibrium.
Consider the AD-AS model discussed during the lectures. Assume that the aggregate demand curve is given by Y=8-0.5 π, that the long run aggregate supply curve is given by Yp=7, that the short run aggregate supply curve is given by π = π_expect + 0.3(Y-Yp), and that the monetary rule is given byr=1+0.3 π.
Suppose the economy is suffering a decrease in the potential level of output, due to some ill-designed new regulation. According to the AD- AS model, what is more suitable to offset the subsequent decline in output, an expansionary monetary policy or an expansionary fiscal policy?

- In the New Keynesian model, suppose that in the short run the central bank cannot observe aggregate output or the shocks that hit the economy. However, the central bank would like to come as close as possible to economic efficiency. That is, ideally the central bank would like the output gap to be zero.

The Federal Reserve can use expansionary/contractionary policy to shift the AD curve. Use the AD–AS framework to show how monetary policy should be used to return output to potential GDP when: (i) the aggregate demand curve intersects the short-run aggregate supply curve to the left of potential GDP; and (ii) the aggregate demand curve intersects the short-run aggregate supply curve to the right of potential GDP. Given that the economy can correct itself and return to potential GDP, why would the Fed pursue contractionary monetary policy following a negative aggregate supply (inflation) shock?
