(Solution) - Consider an economy described by the production function Y -(2025 Original AI-Free Solution)

Paper Details

Consider an economy described by the production function: Y = F(K, L) = K0.3L0.7.
a. What is the per-worker production function?
b. Assuming no population growth or techno-logical progress, find the steady-state capital stock per worker, output per worker, and consumption per worker as a function of the saving rate and the depreciation rate. c. Assume that the depreciation rate is 10 percent per year. Make a table showing steady-state capital per worker, output per worker, and consumption per worker for saving rates of 0 percent, 10 percent, 20 percent, 30 percent, and so on. (You will need a calculator with an exponent key for this.) What saving rate maximizes output per worker? What saving rate maximizes consumption per worker?
d. (Harder) Use calculus to find the marginal product of capital. Add to your table the marginal product of capital net of depreciation for each of the saving rates. What does your table show?
