Consider the following economy: cd = = 580 + [0.50 × (Y-T)] - 60r d = 470-50r Desired consumption: Desired investment: Real money demand: Full-employment output: L = 0.6Y-110i Y = 2,190 Expected inflation: T² = 0.03 In this economy the government always has a balanced budget, so T = G, where T is total taxes collected. a. Suppose that T = G = 150 and that M = 4,360. Use the classical IS-LM model to determine the equilibrium value of the real interest rate. (Hint: In the classical model output always equals its full-employment level.) The equations are: IS: Y = 2,250 - 220r LM: Y = 6 +7,267 (H) + 183r The initial equilibrium values of output, real interest rate, consumption, investment and the price level were found to be: Output = 2,190 Real interest rate = 0.27 Consumption = 1,583.8 Investment = 456.5 Price level = 3.40 b. Suppose that the money supply changes to M = 4,140. Use the classical IS-LM model to find the general-equilibrium values of the real rate of interest, consumption, investment, and the price level. Real rate of interest, r = (Enter your response rounded to two decimal places.)
