An economy has full-employment output of 1,000. Planned consumption and investment are:
C = 200 + 0.8(Y - T) - 500r
I = 200 - 500r.
Government purchases are G = 196, and taxes are T = 20 + 0.25Y . Real balance demand is:
MP = 0.5Y - 250r - 25.
The nominal money supply is M = 9890.
1. What are the equilibrium values of the interest rate, price level, consumption and investment?
2. Suppose that government purchases are increased to G = 216. What are the new short-run equilibrium values of the interest rate, price level, consumption and investment?
