- now we look at the role taxes play in determining equilibrium income. Suppose we have an economy described by the following functions:
C = 500 + 0.8YD
I = 700
G = 300
TR = 100
TA = 400
NX = -100
a. Calculate the equilibrium level of income and the multiplier in this model.
b. Calculate also the budget surplus, BS.
c. Suppose that TA increases to 500. What is the new equilibrium income?
