Question

The following set of equations describe an economy:

C = 14,400 + 0.5 (Y − T) − 40,000r

Ip = 8,000 − 20,000r

G = 7,800

NX = 1,800

T = 8,000

Y* = 40,000

Suppose that the real interest rate (r) is 10%. Is the economy in long run equilibrium? If not, what real interest rate should central bank set to restore the economy back to the long run equilibrium? And what methods can central bank use to adjust the interest rate? (Round your answer to 2 decimal places)
