Economics 302 Name ______________________________ Quiz #4 Section Number ______________________ 5/3/07 Student ID Number ___________________ You are given the following information about a closed economy. Y = C + S + T Y = E in equilibrium C = a + b(Y – T) = 320 + .5(Y – T) r = 10 – (0.1)I G = 100 M S = nominal money supply = 400 (M/P) D = demand for real money balances is expressed by the following equation: r = (.1)Y – 72 – (.01)(M/P) D P = 1 initially T = (.2)Y 1. Using the above information, derive the IS equation for this economy. In your derivation indicate your reasoning: i.e., what underlies this equation? a. (.25 points) Explanation underlying your derivation of the IS curve: b. (.25 points) Derivation of the IS curve: 2. Using the above information, derive the LM equation for this economy. In your derivation indicate your reasoning: i.e., what underlies this equation? a. (.25 points) Explanation underlying your derivation of the LM curve:
