Use the accompanying graph to answer the questions that follow. (LO1, LO2) a. Suppose this monopolist is unregulated. (1) What price will the firm charge to maximize its profits? (2) What is the level of consumer surplus at this price? b. Suppose the firm’s price is regulated at $80. (1) What is the firm’s marginal revenue if it produces 7 units? (2) If the firm is able to cover its variable costs at the regulated price, how much output will the firm produce in the short run to maximize its profits? (3) In the long run, how much output will this firm produce if the price remains regulated at $80?

That is, each of the N firms produces a product that "looks" different from the products of its competitors, but that "really" isn't any different. However, each firm is able to fool some of the buying public. Specifically, each of the N firms (which are identical and have zero marginal cost of production) has a captive market -consumers who will buy only from that firm. The demand generated by each of these captive markets is given by the demand function Pn A- Xn , where Xn is the amount supplied to this captive market and Pn is the price of the production of firm n. There is also a group of intelligent consumers who realize that the products are really undifferentiated.

- 9. Suppose Warner Music and Universal Music are in a duopoly and currently limit themselves to 10 new artists per year. One artist sells 2 million songs at $1.25 per song. However, each label is capable of signing 20 artists per year. If one label increases the number of artists to 20 and the other stays the same, the price per song drops to $0.75, and each artist sells 3 million songs. If both labels increase the number of artists to 20, the price per song drops to $0.30, and each artist sells 4 million songs. Explain how revenue payoffs for each scenario are calculated. If this game is played once, how many artists will each producer sign, and what will be the price of a song? If this game is played every year, how many artists will each producer sign, and what will be the price of a song?arrow_forward1.Briefly state the basic characteristics of pure competition, pure monopoly, monopolistic competition, and oligopoly.
