Essay

-The table above shows Purpleland's economy aggregate demand and supply schedules. Purpleland's potential GDP is $675 billion.
a) Plot the aggregate demand curve, the short-run aggregate supply curve, and the long-run aggregate supply curve.
b) What are the short-run equilibrium real GDP and price level in Purpleland?
c) What is the long-run equilibrium real GDP?
d) Is Purpleland's short-run macroeconomic equilibrium a full-employment equilibrium, below full-employment equilibrium, or above full-employment equilibrium? What is the recessionary gap (if any)? What is the inflationary gap (if any)?
e) Suppose aggregate demand increases by $150 billion. Plot the new aggregate demand curve. How do real GDP and the price level change in the short run?
f) Is Purpleland's new short-run macroeconomic equilibrium a full-employment equilibrium, below full-employment equilibrium, or above full-employment equilibrium? What is the recessionary gap (if any)? What is the inflationary gap (if any)?
