IS-LM Model (Based on Mankiw Ch. 12 #3). Use the information about the following economy to build the IS-LM model. a. The consumption function is given by C = 300 + 0.6(Y - ). The investment function is / = 700 - 80r. Government spending and taxes are both 500. Graph the IS curve for this economy. Be sure to label the x- and y-axes. b. The money demand function is (M/p) = Y - 200r. The money supply M is 3,000 and the price level P is 3. On the same graph as in part a.), graph the LM curve. c. Find the equilibrium interest rate r and the equilibrium level of income Y. Label the equilibrium values on your graph. d. Suppose that government spending is increased from 500 to 700. How does the IS curve shift? What are the new equilibrium interest rate and level of income? Show the shift and the new equilibrium on your graph. e. Suppose instead that the money supply is increased from 3,000 to 4,500. How does the LM curve shift? What are the new equilibrium and level of income? On a new graph, show the original IS and LM curves and then show the shift and the new equilibrium. f. With the initial values for monetary and fiscal policy, suppose that the price level rises from 3 to 5. What happens? What are the new equilibrium interest rate and level of income? On a new graph, show the original IS and LM curves and then show the shift and the new equilibrium. g. . For the initial values of monetary and fiscal policy, derive and graph an equation for the aggregate demand curve (Hint: Solve the IS and LM curves in terms of r. Then combine them and solve for Y in terms of P.). What happens to this aggregate demand curve if fiscal or monetary policy changes, as in parts d.) and e.) (simply state which direction the aggregate demand curve shifts in each case)?QT.
