3. Consider the open economy IS / LM model with the following functions: 0 = 0.5(Y T), I = 1500 2507", NX = 1000 2506, L(Y, 7") = 0.5Y 500?" (money demand), CF 2 500 2507'. Taxes, government purchases, the money supply, and price level are T = 1000, G = 1500, M = 1000, and P = 1. Calculate the equilibrium values for GDP Y, the interest rate 7", consumption 0, investment I, net capital outow CF, net exports N X , and the exchange rate 6
