6. The accompanying diagram shows the demand, marginal revenue, and marginal cost of a monopolist. (LO1, LO3, LO5)
a. Determine the profit-maximizing output and price.
b. What price and output would prevail if this firm’s product were sold by price-taking
firms in a perfectly competitive market?
c. Calculate the deadweight loss of this monopoly.
8. The elasticity of demand for a firm’s product is –2.5 and its advertising elasticity of demand is 0.2. (LO8)
a. Determine the firm’s optimal advertising-to-sales ratio.
b. If the firm’s revenues are $40,000, what is its profit-maximizing level of advertising?
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?
5. (a) Assume that two firms A and B are in different industries (like computer software and computer hardware). What impact will a merger between these two firms have on the number of firms in each industry after the merger? Please give an explanation.
(b) Current automobile companies are facing a shortage of computers chips used in cars to run various parts of the car, and therefore supply of cars has decreased since a necessary part(s) is not available. If an auto company like General Motors (GM) decided to buy a chip manufacturing company to ensure that it did not face a chip shortage in the future, would such a purchase lead to more concentration in either the auto industry or the chip-manufacturing industry? Please give an explanationexplanation.

Imagine an N firm oligopoly for "nominally differentiated" goods. 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. These…arrow_forward

If all fishermen had abided by the agreement, yields could have been maintained at high levels. LO4 Model this situation as a prisoner’s dilemma in which the players are Company A and Company B and the strategies are to keep the quota and break the quota. Include appropriate payoffs in the matrix. Explain why overfishing is inevitable in the absence of effective enforcement of the quota agreement. Provide another environmental example of a prisoner’s dilemma. In many potential prisoner’s dilemmas, a way out of the dilemma for a would-be cooperator is to make reliable character judgments about the trustworthiness of potential partners. Explain why this solution is not avail- able in many situations involving degradation of the environment.arrow_forward9. 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_forward
- 9. Firms 1 and 2 are proposing to merge. They offer symmetrically differentiated products and have identical costs and, therefore, identical premerger prices. (Note that “symmetrically differentiated products” means that if they charge the same price, then they have the same demand.) The common premerger price for firms 1 and 2 is $90, and the common marginal cost is $60. If firm 1 were to raise its price to $100, we know that its demand would drop by 20 units and firm 2’s demand would rise by 5 units. a. Assume the merger would reduce marginal cost by 10 percent. Using UPP, is there reason to be concerned with the merger? b. Suppose the prospective merger partners want to convince the DOJ that the merger will not raise price. Using UPP, how large must they argue the efficiency is? c. Suppose there are improved estimates of firms’ demand functions and now we know that if firm 1 were to raise its price to $100, its demand would (still) drop by 20 units, but firm 2’s demand would rise by…arrow_forward3.
