Short answer questions
Please write clearly. If I cannot understand your writing, I cannot give you the credits for the
questions.
1. Your day as the chair of the FED: Suppose you are appointed as the chair of the US Federal
Reserve. “With the sole goal of stabilizing output”, explain how and why you would change the
interest rate in response to the following shocks. Show the effects on the economy in the short
run using the IS-MP diagram. Be sure to discuss what changes in the model specifically. Provide
detailed intuitive explanation in words as well. (You can assume that the economy, before the
shock, is at the benchmark point.) (12 points)
A. Firms become pessimistic about the state of the economy and hence decrease the investment.
(Note that this happens initially without any change in the interest rate).
B. Suppose some of Latin American economies succumb to a recession and significantly reduce
their demand for the U.S. goods.
2. Your day as the chair of the FED: Suppose you are appointed as the chair of the US Federal
Reserve. “With the sole goal of stabilizing inflation at a low level”, explain how and why you
would change the interest rate in response to the following shock. Show the effects on the
economy in the short run using the US IS-MP-and Philips curve diagrams. Provide detailed
intuitive explanation in words as well. In your analysis, be sure to discuss how FED can
stabilize the inflation at the level that they desire. (You can assume that the economy, before the
shocks, is at the benchmark point.) (10 points).
Suppose France experiences a boom and significantly increase their demand for the U.S. goods
