Assume that in 2011, the following prevails in the Republic of Nurd:

Assume that households consume 80 percent of their income, they save 20 percent of their income, MPC = .8, and MPS = .2.
That is, C = .8Yd and S = .2Yd.

a. Is the economy of Nurd in equilibrium? What is Nurd’s equilibrium level of income? What is likely to happen in the coming months if the government takes no action?

b. If $200 is the “full-employment” level of Y, what fiscal policy might the government follow if its goal is full employment?

c. If the full-employment level of Y is $250, what fiscal policy might the government follow?

d. Suppose Y = $200, C = $160, S = $40, and I = $40. Is Nurd’s economy in equilibrium?

e. Starting with the situation in part

d, suppose the government starts spending $30 each year with no taxation and continues to spend $30 every period. If I remains constant, what will happen to the equilibrium level of Nurd’s domestic product (Y)? What will the new levels of C and S be?

f. Starting with the situation in part

d, suppose the government starts taxing the population $30 each year without spending anything and continues to tax at that rate every period. If I remains constant, what will happen to the equilibrium level of Nurd’s domestic product (Y)? What will be the new levels of C and S? How does your answer to part f differ from your answer to part e? Why?
