4. Consider the following production function: Y = K$^\frac{1}{3}$(AN)$^\frac{2}{3}$, where both the population and the pool of labor are growing at a rate n = .07, the capital stock is depreciating at a rate d = .03, and A is normalized to 1. a. What are capital's and labor's shares of income? b. What is the form of this production function? c. Find the steady-state values of k and y when s = .20. d. At what rate is per capita output growing at the steady state? At what rate is total output growing? What if total factor productivity is increasing at a rate of 2 percent per year (g = .02)?

Step 1
The marginal product of capital is the derivative of the production function with respect to capital (K): MPK = ∂Y/∂K = 5K^4 * A * N Show more…

4. Suppose that an economy's production function is Cobb-Douglas with parameter a=0.3. a. What fractions of income do capital and labor receive? b. Suppose that immigration increases the labor force by 10 percent. What happens to the total output (in percent)? The rental price of capital? The real wage? c. Suppose that a gift of capital from abroad raises the capital of stock by 10 percent. What happens to the total output (in percent)? The rental price of capital? The real wage? d. Suppose that a technological advance raises the value of the parameter A by 10 percent. What happens to the total output (in percent)? The rental price of capital? The real wage?

Assume the production function is given by: Y = K^(1/2) * L^(1/2) a. Write the production function in per worker terms (y = f(k)). b. Assume that the per worker level of capital in the steady state is 4, the depreciation rate is 5% per year, and population growth is 5% per year. Does this economy have "too much" or "too little" capital? How do you know? [Show your work].
Andrew D.
Suppose that output is growing at 3 percent per year and the elasticities of output with respect to capital and labor are 0.3 and 0.7, respectively. a) If both capital and labor grow at 1 percent per year, what would the growth rate of total factor productivity have to be? b) What if both the labor and the capital stocks are fixed?
