Q1: AD-AS Model
Based on Abel, Bernanke and Croushore, 10th edition, Chapter 9, Numerical Problems, No. 5.
Consider the following eeonomy:
• Desired consumption
= 1275 + 0.5(Y – T) – 200r.
(1)
• Desired invest ment
Id = 900 – 200r
(2)
• Real money demand
L = 0.5Y – 200i
(3)
Full employment out put Y = 4600 and expected inflation is a = 0.
(a) Suppose that T= G= 450 and that M = 9000.
• Find an equation describing the IS curve.
HINT: Set desired national saving and investment exqual; salve for relatkonship between r and Y
• Find an equation describing the LM curve.
[HINT: Set real money supply and demmand equal; solve for relatkonship between rand Y, given P.
• Finally, find an equation for the aggregate demand curve.
HINT: Use the IS and LM expuatiıns to find a relationship between Y and P.

(b) Calculate the general equilibrium values of output, consumption, investment, the real
interest rate, and price level.
(c) Suppose that T = G = 450 and that M = 4500. What is the equation for the aggregate
demand curve now? What are the general equilibrium values of output, consumption,
invest ment, the real interest rate, and price level? Assume that full employment output
Y is fixed.
