Suppose the economy is experiencing a recessionary gap.

a. Draw a graph showing aggregate demand, short-run aggregate supply, and long-run aggregate supply. Label both axes, all curves, and the recessionary gap. Label the actual output level as Y₁, the actual price level as PL₁, and the full employment output level as Y_f.

b. Explain one specific expansionary fiscal policy that Keynesian economists might suggest to eliminate the recessionary gap.

c. Show how the policy you explained in part b would change your graph if the policy were successful.
