Suppose that people finally realize that they must save a larger proportion of their income in order to retire and that they simultaneously begin to use new technology that allows them to reduce their holdings of real cash balances as a proportion of their income. Use the IS-LM model to illustrate graphically the impact of these two changes in household behaviour on output and interest rates. Be sure to label: i. the axes; ii. the curves; iii. the initial equilibrium values; iv. the direction the curves shift; and v. the terminal equilibrium values.

Two identical countries, Alpha and Beta, can be described by the IS-LM model in the short run. The governments of both countries cut taxes by the same amount. The Central Bank of Alpha follows a policy of holding a constant money supply. The Central Bank of Beta follows a policy of holding a constant interest rate. Compare the impact of the tax cut on income and interest rates in the two countries.

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?
