  1. an increase, an increase. B. an increase, a decrease.

  1. Suppose that the Fed cuts money supply. Discuss the effect of this policy on the nominal interest rate, the real interest rate, and output in the short run. In discussing, use an IS-LM graph with correctly labeled curves and axes.  If a curve or curves shift in a certain way, explain why the curve or curves shift that way.

 

  1. Repeat question 14 in the medium run. Do not use a graph, but use Y = C+I+G in your explanation.

  1. D 2. B 3. A                 4. A                 5. E                  6. B
  2. A 8. C. 9. A                 10. A               11. B               12. A
  3. A
  4. The LM curve shifts up but the IS curve stays the same, increasing both the nominal and real interest rates but decreasing output in the short run. Thus, if we started from the natural (real) interest rate rn and natural output Yn , the real interest will be higher than the natural rate, but output will be lower than the natural level.

 

  1. The real interest rate and output both return to the natural level. The nominal interest will be lower.

 

  1. Choose P, and save 20 and enjoy 500 in 2016. The 20 you save in 2016 will be more than 20 in 2018 due to the interest rate, and P is better than Q. By an analogous argument, Q is better than R.  Thus, P must be better than Q and R by transitivity.
