Review Sheet for Mini Exam 4 Expect a couple of multiple choice questions from chapter 5 (open economy). A graphing question from chapter 5 is also a possibility. Expect multiple choice and open ended questions from chapter 7 (money market). You should be familiar with the equations and be able to derive the growth rate equations. Here are some practice problems: 1. Suppose real money demand is L = 0.8 Y – 100,000 ( r + π e ). If the nominal money supply is 12,000, real output is 15,000, the real interest rate is .02, and the expected inflation rate is .01, then the price level is__________? 2. If the nominal money supply doubles while real money demand is unchanged, what happens to the price level? If real money demand doubles while the nominal money supply is unchanged, what happens to the price level? ANSWERS: 1. 3, 2. It doubles; It falls by 1/2, 3. ended. I recommend that you go through the short run and long run effects of a shift in each curve.

You should know how the government seeks to affect the macroeconomy through both fiscal and monetary policy....
