Does a monopolist have a supply curve? Briefly explain. (Hint: Look again at the definition of a supply curve in Chapter 3 on page 83 and consider whether this definition applies to a monopolist.)
Draw a graph that shows a monopolist earning a profit. Be sure your graph includes the monopolist's demand, marginal revenue, average total cost, and marginal cost curves. Be sure to indicate the profit-maximizing level of output and price.
The U.S. Postal Service (USPS) is a monopoly because the federal government has blocked entry into the market for delivering first-class mail. Is the USPS also a natural monopoly? How can we tell? What would happen if the law preventing competition in this market were removed?
When homebuilders construct a new housing development, they usually sell to a single cable television company the rights to lay cable. As a result, anyone buying a home in that development is not able to choose between competing cable companies. Some cities have begun to ban such exclusive agreements. Williams Township, Pennsylvania, decided to allow any cable company to lay cable in the utility trenches of new housing developments. The head of the township board of supervisors argued: "What I would like to see and do is give the consumers a choice. If there's no choice, then the price [of cable] is at the whim of the provider." In a situation in which the consumers in a housing development have only one cable company available, is the price really at the whim of the company? Would a company in this situation be likely to charge, say, \(\$ 500\) per month for basic cable services? Briefly explain.
In China, the government owns many more firms than do governments in the United States. A former Chinese government official argued that a number of government-run industries such as oil refining were natural monopolies. Is it likely that oil refining is a natural monopoly? How would you be able to tell?
