In the Mundell"Fleming model on a Y " e graph, the curves labeled IS* and LM* are
labeled that way as a reminder that:
A) the price level is held constant at the world price level p*.
B) the interest rate is held constant at the world interest rate r*.
C) the exchange rate is held constant at the world exchange rate e*.
D) output is held constant at the full employment level.
Assume that in a certain economy the LM curve is given by Y = 2,000r " 2,000 +
2(M/P) + u, where u is a shock that is equal to +200 half the time and "200 half the
time, and the IS curve is given by Y = 8,000 " 2,000r. The price level (P) is fixed at 1.0.
The natural rate of output is 4,000. The government wants to keep output as close as
possible to 4,000 and does not care about anything else. Consider the following two
policy rules: i. Set the money supply M equal to 1,000 and keep it there. ii. Manipulate
M from day to day to keep the interest rate constant at 2 percent.
a. Under rule i, what will Y be when u = +200? Under rule i, what will Y be when u =
"200?
b. Under rule ii, what will Y be when u = +200? Under rule ii, what will Y be when u =
"200?
c. Which rule will keep output closer to 4,000?
