TRUE/FALSE/EXPLAIN
1)If the price of a competitive firm's output increases, the firm responds in the short run by demanding more labor.
Answer: True. The firm wishes to sell more output and can do so only by hiring more labor.
Diff: 0
Topic: Competitive Factor Markets
2)If the competitive firm maximizes profit by selecting labor rather than output, it will earn greater economic profit.
Answer: False. Whether the firm maximizes profit by selecting output or labor, the resulting profit is the same. Since MC = w/MP, setting MC = p is the same as setting w = p * MP.

Topic: Competitive Factor Markets
3)If a firm has market power in the output market but buys labor in a competitive market, it will hire the same quantity of labor that a competitive firm will.
Answer: False. Since the firm has market power, it must lower price if it wishes to sell more. It will wish to sell fewer units than a competitive firm, and, therefore, hire less labor than a competitive firm does.

4)If a monopolist in the output market purchases its monopoly supplier of labor, consumers benefit.
Answer: True. The firm now pays a competitive price for its labor instead of the monopoly price. This lower wage shifts the firm's marginal cost curve downward. The result is a lower price charged to consumers.

PROBLEMS
1)How does a competitive firm's demand for labor react to a specific tax on each unit of output it sells?
Answer: The price the firm receives for each unit of output is now p' - t instead of p where p' is new price paid by consumers. Assuming that p' does not exceed p by the full amount of the tax, the demand for labor shifts downward and intersects the wage line at a lower quantity of labor.

2)XYZ Co. operates in a competitive market. Its production function is q = L K . The exponents, and , are both less than 1. The firm's capital is fixed, and it takes the wage and price as given. Derive the firm's short-run demand for labor as a function of K, w, and p. How does the firm react to an increase in the wage rate?
Answer: MPL= L-1K. The firm sets w = p(L-1K). Rearranging to solve for L yields L = (w/pK)1/(-1). Since < 1, L increases when p and K increase, and decreases when w increases.

3)XYZ Co. operates in a competitive market. Its marginal product of labor is 1/L, and it takes the wage and price as given. Derive the firm's short-run demand for labor as a function of w and p. How much labor will the firm hire if w = 2 and p = 10?
Answer: Setting w = p * MPL yields w = p/L or L = p/w. At w = 2 and p = 10, the firm hires 5 units of labor.

4) Suppose there are profit maximizing, competitive buyers and sellers of labor in an
industry, and the amount of capital is fixed for each firm. Explain under what condition the output price will equal the wage rate.
Answer: The profit-maximizing buyer of labor sets the output price equal to the marginal cost of producing an additional unit of output. The marginal cost of output when capital is fixed equals the wage rate divided by the marginal product of labor. If the marginal product of labor equals one, then the output price will equal the wage rate.
