Find the profit maximizing level of k and h. What is the quantity of widgets produced? (b) Now assume that the wage rate increases from 2 to 4. Find the short-run demand for labor. In other words, keeping capital fixed at the profit maximizing level from part (a), find the profit- maximizing level of labor demanded. How does the quantity of widgets produced change? (c) Now find the long-run demand for labor and capital (find the profit maximizing level of labor and capital demanded allowing both to vary). How does the quantity of widgets produced vary between the short- and long-run
