a. Using the AD-AS model, show what a contractionary gap looks like graphically. Make sure to label the axis, curves, equilibrium, and contractionary gap. Explain in a sentence or two why this is a problem. (10 points)

b. On a new graph, show the effect on the economy from part a if the Federal Reserve decides to lower the discount rate, but that this is only enough to half close the contractionary gap. Explain in a sentence or two what has happened to the short-run equilibrium of this economy. (10 points)

c. On a new graph, show the effect on the economy from part b if the government lowers taxes enough to fully close the contractionary gap. Explain in a sentence or two what has happened to the short-run equilibrium of this economy. (10 points)

d. Which school of thought on business cycles was used in this scenario? How do you know? What is a benefit of this school? What is a problem associated with this school? Pick one other school of thought and explain why they would argue against this school. (10 points)

a. Using the AD-AS model, show what an expansionary gap looks like graphically. Make sure to label the axis, curves, equilibrium, and expansionary gap. Explain in a sentence or two why this is a problem. (10 points)

b. On a new graph, show the effect on the economy from part a if the Federal Reserve decides to sell securities through open market operations, but that this is only enough to half close the expansionary gap. Explain in a sentence or two what has happened to the short-run equilibrium of this economy. (10 points)
