QUESTION 1:
Consider a country that is characterized by the following production function:
Y= 5K.5 L.5. Assume that the rate of depreciation as well as the rate of saving are each
.10. Also assume that there is no technological progress nor population growth.
a. What is the steady state level of capital per worker?
b. What is the steady state level of output per worker?
c. Suppose that the savings rate remains at .10 while the rate of depreciation increases to .20. What now happens to steady state level of capital per worker and output per worker?
QUESTION 2:

QUESTION 3:
Suppose that the government of a country increases fiscal spending. According to the real business cycle theory, what will be the impact on the economy due to this change in government spending?
QUESTION 4:
The production function of a country X is given by: y = 150n - .5n2

a. What is the equation of New Keynesian Aggregate Supply curve?
b. If the labor market had been of the New Classical model, what would the equation of the Lucas Aggregate Supply curve be?
