Question
Final output in the economy is pro-
duced using capital K and labor L. The production function is:
Y = ĀK/ L^/5
Assume that the supply of all inputs are exogenous and equal to L and K. Perfectly compet-
itive firms are price-takers and choose how much capital and labor to demand by maximizing
profits. Let w and r denote the wage and rental rate of one unit of labor and capital respec-
tively.
