The economy of a country is categorized by the following equations: Desired consumption cd = 1400 + 0.5(Y – T) – 200r Desired investment id = 900 – 200r Real money demand L = 0.5Y – 200i Full-employment output Y = 4600 Expected inflation ne = 0 The government always runs a balanced budget. a. (6 points) Find an equation for the IS curve. b. (6 points) Find an equation for the LM curve. c. (6 points) Suppose that G = 920 and M = 9000. Find an equation for the aggregate demand curve. What are the general equilibrium values of output, consumption, investment, the real interest rate, and the price level? d. (6 points) Suppose now that G = 920 and M = 4500. What is the equation for the aggregate demand curve? What are the equilibrium values of output, consumption, investment, the real interest rate, and the price level? Assume the full-employment output is fixed. Comment on money neutrality. e. (6 points) Repeat part (d) for G = 800 and M = 9000.
