QUESTIONS FOR DISCUSSION Question 11. The response of investment to fiscal policy Using the IS – LM diagram, show the effects on output and the interest rate of a decrease in government spending. EXERCISES Question 12: Consider the goods market model with investment that depends on both income and the interest rate: _ I = I + b 1 Y – b 2 i; Solve for equilibrium output. At a given interest rate, is the effect of a change in autonomous spending bigger than what it was considering investment exogenous? Why? 4ECON005C Exploring Economics - Macroeconomics Question 13. Consider the following IS – LM model: C = 200 + 0.25Yd I = 150 + 0.25Y – 1000i G = 250 T = 200 (M/P) d = 2Y – 8000i M/P s = 1600 A. Derive the IS relation. (Hint: You want an equilibrium with Y on the left side and everything else on the right.) B. Derive the LM relation. (Hint: It will be convenient for later use to rewrite this equation with i on the left side and everything else on the right.) C. Solve for equilibrium real output. (Hint: substitute the expression for the interest rate given by the LM equation into the IS equation and solve for output.) D. Solve for the equilibrium interest rate. (Hint: substitute the value you obtained for Y in part (c) into either the IS or LM equations and solve for i. If your algebra is correct you should get the same answer from both equations. E. Solve for the equilibrium values of C and I. F. Verify the value you obtained for Y by adding C, I and G comparing to answer from (c). Download 173.57 Kb. Do'stlaringiz bilan baham: |
