Assume that an economy is described by the IS curve Y = 3,600 + 3G - 2T - 150r and the LM curve Y = 2 M / P + 100r [or r = 0.01Y - 0.02 (M / P)]. The investment function for this economy is 1,000 - 50r. The consumption function is C = 200 + (2 / 3)(Y - T). Long-run equilibrium output for this economy is 4,000. The price level is 1.0.

a.Assume that government spending is fixed at 1,200. The government wants to achieve a level of investment equal to 900 and also achieve Y = 4,000. What level of r is needed for I = 900? What levels of T and M must be set to achieve the two goals? What will be the levels of private saving, public saving, and national saving?
