Spring 2013: Intermediate Macroeconomics Read each question carefully and answer on the paper provided. EXPLAIN your answers; the quality of your
reasoning will determine your points. Also remember, however, that long-winded answers are not needed (it probably
means youâ€™re wrong if the answer is super long). Give a numerical answer when appropriate. 1. [15 points] Suppose that the production function for an economy is Cobb-Douglas and is given by:
Y = 50K~3L7 a. Suppose also that K = 1000 and L = 1000. Calculate GDP. This should be EASY. Plug in the numbers and look carefully.

2. [20] Refer back to (1) and assume that your economy is closed. Suppose that C = 100 + .9(Y â€” T), l = 10,000 â€” 1,000r, and G =d1,750. (There is no foreign segor.) Suppose further that T = 1,500. Calculate private/publicdand
national savings. Calculate the real interest rate that puts this economy in equilibrium. Draw a graph that represents your equilibrium answer. . PPM/Art Saw N; s, : 47 mi ï¬‚â€˜l}:

that if the money supply increases by 4%, prices will increase by the same amount. What will happen to other
nominal economic variables? Will any real variables change? What must happen to change any real variables in the
classical model? Assuming that purchasing power parity holds, what will happen to the nominal exchange rate if
foreign prices are constant while the domestic money supply increases by 4%? â€˜
