D
Use the following two statements to answer this question: I. A firm can exert monopoly power if and only if it is the sole producer of a good. II. The degree of monopoly power a firm possesses can be measured using the Lerner Index: L = (P− AC)/AC. A. I is false, and II is true. B. Both I and II are true. C. I is true, and II is false. D.

D
A certain town in the Midwest obtains all of its electricity from one company, Northstar Electric. Although the company is a monopoly, it is owned by the citizens of the town, all of whom split the profits equally at the end of each year. The CEO of the company claims that because all of the profits will be given back to the citizens, it makes economic sense to charge a monopoly price for electricity. True or false? Explain. A. True. Since the monopoly price is higher than marginal cost, the firm earns positive economic profits. And since these profits are given back to the citizens, they are better off. B. True. Since electric utilities are natural monopolies, monopoly pricing is most efficient. And since any profits are given back to the citizens, they are better off. C. False. Since the monopoly price is higher than marginal cost, the firm earns negative economic profits. So, there are no profits to give back to the citizens. D. False. Since the monopoly price is higher than marginal cost, more than the efficient quantity is produced resulting in a deadweight loss. E. False. Since the monopoly price is higher than marginal cost, less than the competitive quantity is produced, so there is still a deadweight loss even if all the profits are given back to the citizens.
E
Rent seeking is A. one firm consistently following the actions of another. B. charging the maximum price allowed by a regulatory agency based on a firm's expected rate of return.

E
Which of the following is least likely to affect the amount of monopoly power a firm is likely to have? A. The number of firms in the market. B. The extent to which related firms compete. C. The price elasticity of demand. D. The availability of close substitutes. E. The shape of the market supply curve.
