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. The Baxter brothers are arguing about which price to charge customers per download.  The accompanying table shows the demand schedule for their film.

Remember, MR = ΔTR/ΔQ

(Marginal Revenue = Change in total revenue divided by change in quantity)

 Price of download Quantity of downloads demanded Total Revenue Marginal Revenue \$10 0 xx 8 1 6 3 4 6 2 10 0 15

b. Bob is proud of the film and wants as many people as possible to download it.  Which price would he choose? How many downloads would be sold? (For this part of the question, do not account for the \$4.00 Internet download fee.)

c. Bill wants as much total revenue as possible. Which price would he choose? How many downloads would be sold? (For this part of the question, do not account for the \$4.00 Internet download fee.)

d. Ben wants to maximize profit. Which price would he choose? How many downloads would be sold? (For this part of the question, do not account for the \$4.00 Internet download fee.)

e. Brad wants to charge the efficient price. Which price would he choose? How many downloads would be sold?

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? (If the red triangle is not on the diagram, you may need to readjust it to its original format.  When you type into the document, the triangle may move.)

Price?
Quantity?

Red Triangle?

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?

Profits or Lose Money?

Produce or Not Produce?

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.

Profit, Lose Money, or Break Even?
Area Marked by Red Dashed Lines?

What does this mean for the monopolist?

Diagram 4.  Price ceiling \$0.50
