Transcribed Image Text:C = 50 + 0.9 · (Y – T)
I = 50 – 1000 - r
where Y is real output and r is the real interest rate. Government purchases and taxes are
Ğ = 500, T = 500.
The money market equilibrium curve-or LM curve-is
where P is the price level and i is the nominal interest rate. The Central Bank (CB) is initially supplying
M = 10000 units of money, and expected inflation is zº = 0.05. The long-run aggregate supply (LRAS) is
Y, = 1000.
Suddenly, there is a climate shock that changes the marginal propensity to consume (MPC), and the
consumption function changes to
C' = 50 + 0.8 · (Y – T).
1. Explain how the short-run values of (r, i) are determined before the climate shock.
2. Which, if any, of the graphs from Appendix A best depicts the short-run change in the interest rate(s)
due to the climate shock? Explain.
3. Which, if any, of the graphs from Appendix B best depicts the short-run change in output and price
due to the climate shock? Explain.
4. Which, if any, of the graphs from Appendix C best depict the change in the Keynesian cross due to
the climate shock? Explain.
