The graph below shows a firm's isoquants and isocosts. The firm is initially producing Q=20 with the cost minimizing combination of K and L, where Q is output, Kis capital and L is labor. Suppose the owner decides to expand production to Q=40. However, he signed a lease on the capital necessary to produce Q=20, which he cannot get out of in the short run. In order to...
