С (Y — T) 3D 1200+ 0.8(Y — T) I(r) = 100 – 3r - G 3D 200;T — 200; r 3D 5; Eх — Im — 0 1. Assume the Federal Reserve is successful and targeting a real interest rate of 2. Find the new equilibrium level of Y (assuming autonomous consumption is still 1100). Was the policy successful and returning economic activity to Yp?

Consider an economy described by the IS-LM model. You are given the following data: MPC = 0.6, C * = 10 AE = Y G = 75,T = 60 I(r) = 500 – 1200r M = 250, P = 5 - k(r)Y = 0.1Y – 10r (A) Write out the planned expenditure function and solve for equilibrium output as a function of the interest rate (the IS curve). (B) Using the money demand function, solve for equilibrium output given the interest rate in the money market (the LM curve). (C) Using the IS and LM curves, derive equilibrium output and the interest rate.

Consider the following macroeconomy. All amounts are in millions (m.) of $: C = 750 + 0.8 YD I = 1200 G = 150 T = 250 Calculate eqm Y and prove that I=sum of S at this equilibrium. What is meant by the “Paradox of Thrift” (POT)? Go back to the original eqm of part a. Now prove using multiplier analysis that the POT holds in this economy by assuming that the change in co is -$50 m. As part of your answer, explain “intuitively” why this paradox exists. Show what happens in the Z-Y space graph.

Consider an economy in which taxes, planned investment, government spending on goods and services, and net exports are autonomous, but consumption and planned investment change as the interest rate changes. You are given the following information concerning autonomous consumption, the marginal propensity to consume, planned investment, government purchases of goods and services, and net exports: Ca = 1,500 – 20r, c = 0.6; I= 2,450 – 60r; G= 1,980; NX =- 200; T = 1,750. a. Compute the value of the marginal propensity to save. b. Compute the amounts of autonomous planned spending, Ap, when the interest rate equals 0, 2, 4, and 6. c. Compute the equilibrium levels of income when the interest rate equals 0, 2, 4, and 6. Graph the IS curve. d. Suppose that policymakers decide to reduce the number of troops in Afghanistan, which results in a reduction of government spending of $80 billion.
