Furthermore, firms in this economy are perfectly competitive profit maximizing firms. The input markets for capital and labor are also perfectly competitive.
Use the following information and your knowledge of the relationship between the marginal product of an input and its real price, to calculate the amount of labor and the amount of capital hired in this economy. Show your work.
Y = AKαL1-α where Y = real output, K = units of capital, L = units of labor
A = 2 A = measure of technology in the economy
α = .5 α = capital's share of income
R = 2 R = rental price of capital
P = 2 P = aggregate price level
Y = 800 W = nominal wage rate
W = 2
