If the market price is P4: a. firms will leave the industry and the price will fall in the long run. b. there will be economic profits and firms will enter the industry in the long run. c. the market supply curve will shift to the left and price will fall in the long run. d. the firm will produce q4. e. the price will rise in the long run as economic profits fall to zero. 8. Economic profits in a perfectly competitive industry induce ________, and losses induce ________. a. exit; entry b. entry; entry c. entry; exit d. exit; exit e. entry; shutdown 9. Suppose that the market for haircuts in a community is a perfectly competitive constant-cost industry and that the market is initially in long-run equilibrium. Subsequently, an increase in population increases the demand for haircuts. In the long run, we expect that: a. more firms will enter the market, driving the price of haircuts up and the profits of individual firms back down to zero. b. more firms will enter the market, driving the price of haircuts down and the profits of individual firms back down to zero. c. firms will leave the market, driving the price of haircuts up and the profits of individual firms up. d. firms will leave the market, driving the price of haircuts up and the profits of individual firms back down to zero. e. more firms will enter the market, driving the price of haircuts down and the profits of individual firms up. 10.

Her orchard has fixed costs of $30. If the price of a bushel of apples is $85, we would expect total industry output to: a. rise, and Lilly's output will rise in the long run. b. fall, and Lilly's output will fall in the long run. c. fall, while Lilly's output will rise in the long run. d. rise, while Lilly's output will fall in the long run. e. rise, while Lilly's output will remain unchanged in the long run. 11. Compared to perfect competition: a. monopoly produces more at a lower price. b. monopoly produces where MR > MC, and a perfectly competitively firm produces where P = MC. c. monopoly may have economic profits in the long run, but in perfect competition economic profits are zero in the long run. d. perfect competition may have economic profits in the long run, but in monopoly economic profits are zero in the long run. e. monopoly produces where MR = MC, and a perfectly competitively firm produces where P = MR > MC. 12. The ability of a monopolist to raise the price of a product above the competitive level by reducing the output is known as: a. product differentiation. b. barrier to entry. c. economies of scale. d. patents and copyrights. e. market power.
