Assume a firm is currently employing labor and capital in such a way that the cost minimizing equality is: 100$10 = 200$20 with the left side of the equality representing the MPL/PL and the right side representing the MPK/PK. Suppose the marginal productivity of capital increases by 20 units. How should the firm change its consumption of labor and capital to restore the cost minimizing equality? Whats the answer for this?
