Scenario 15-3
Black Box Cable TV is able to purchase an exclusive right to sell a premium movie channel (PMC) in its market
area. Let's assume that Black Box Cable pays \$150,000 a year for the exclusive marketing rights to PMC. Since
Black Box has already installed cable to all of the homes in its market area, the marginal cost of delivering PMC
to subscribers is zero. The manager of Black Box needs to know what price to charge for the PMC service to
maximize her profit. Before setting price, she hires an economist to estimate demand for the PMC service. The
economist discovers that there are two types of subscribers who value premium movie channels. First are the
4,000 die-hard TV viewers who will pay as much as \$150 a year for the new PMC premium channel. Second, the
PMC channel will appeal to about 20,000 occasional TV viewers who will pay as much as \$20 a year for a
subscription to PMC.
29. Refer to Scenario 15-3. If Black Box Cable TV is unable to price discriminate, what price will it choose to
maximize its profit, and what is the amount of the profit?
a. price = \$20; profit = \$400,000

Scenario 17-2
Consider the problem facing two firms, Firm A and Firm B, in the fast-food restaurant market. Each firm has just
come up with an idea for a new fast-food menu item which it would sell for \$4. Assume that the marginal cost for
each new menu item is a constant \$2, and the only fixed cost is for advertising. Each company knows that if it
spends \$12 million on advertising it will get 2 million consumers to try its new product. Firm A has done market
research which suggests that its product does not have any "staying" power in the market. Even though it could
get 2 million consumers to buy the product once, it is unlikely that they will continue to buy the product in the
future. Firm B's market research suggests that its product is very good, and consumers who try the product will
continue to be consumers over the ensuing year. On the basis of its market research, Firm B estimates that its
initial 2 million customers will buy one unit of the product each month in the coming year, for a total of 24
million units.
