1. Skyscraper City has a subway system, for which a one-way fare is $1.50. There is pressure on the mayor to reduce the fare by one-third, to $1.00. The mayor is dismayed, thinking that this will mean Skyscraper City is losing one-third of its revenue from sales of subway tickets. The mayor's economic adviser reminds her that she is focusing only on the price effect and ignoring the quantity effect. Explain why the mayor's estimate of a one-third loss of revenue is likely to be an overestimate.
2. Bob, Bill, Ben, and Brad Baxter have just made a documentary movie about their basketball team. They are thinking about making the movie available for download on the Internet, and they can act as a single-price monopolist if they choose to. Each time the movie is downloaded, their Internet service provider charges them a fee of $4.

3. Diagram 1., illustrates your local electricity company's natural monopoly. The diagram shows the demand curve for kilowatt-hours (kWh) of electricity, the company's marginal revenue (MR) curve, its marginal cost (MC) curve, and its average total cost (ATC) curve. The government wants to regulate the monopolist by imposing a price ceiling.
Diagram 1.
a. In diagram 2., the government does not regulate this monopolist. Which price will it charge, and how much will it produce? What does the red triangle represent? Why?
Diagram 2. No Regulation
b. In diagram 3., the government imposes a price ceiling equal to the marginal cost, $0.30. Will the monopolist make profits or lose money? Explain the shaded area of the diagram and what it means for the monopolist. If the government does impose this price ceiling, do you think the firm will continue to produce in the long run?
Diagram 3. Price ceiling $0.30
c. In diagram 4., the government imposes a price ceiling of $0.50, will the monopolist make a profit, lose money, or break even? Explain area of the diagram marked by the red dashed lines and what it means for the monopolist.
Diagram 4. Price ceiling $0.50
