- Firms J and K produce compact-disc players and compete againstone another. Each firm can develop either an economy player (E)or a deluxe player (D). According to the best available marketresearch, the firms’ resulting profits are given by the accompanyingpayoff table.a. The firms make their decision independently, and each is seeking itsown maximum profit. Is it possible to make a confident predictionconcerning their actions and the outcome? Explain.Firm KE DE 30, 55 50, 60 Firm JD 40, 75 25, 50b. Suppose that firm J has a lead in development and so can move first.What action should J take, and what will be K’s response?c. What will be the outcome if firm K can move first?A10 Consider an industry with 2 firms, each firm with marginal costs equal to 0. Market demand curve is given by Q=60- P. With 2 firms, we can write Q=Q1+ Q2 . Suppose that each firm behaves as a “Cournot” competitor, that is, choose the optimal quantity maximizing the profits in a strategic way.(a) What would be the values of Q1, and Q2 in equilibrium? (b) Suppose firm 1 can “commit” its level of output in advance. In other words, if firm 1 announces to produce Q1, firm 2 needs to decide how much to produce assuming that firm 1 would indeed produce Q1. What’s the level of Q1 firm 1 would choose to maximize its profit?The following question pertains to ologopoly pricing. a. The following question pertaihs to dominant firm price leadership. Suppose a dominant firm has determined the price for its industry. Then suppose there is an increase in hte price of a substitute product. How will the dominant firm's price, dominant firm's quality, and the fringe firms' quality be affected? Please provide an explanation.

It is based in Chicago(Headquarters) and Trinidad. It sends supplies to firms throughout the United States and the UnitedKingdom. It markets its supplies through periodic mass mailings of catalogs to those firms. Itsclients can make orders over the phone and Madison ships the supplies upon demand.The main competition for Madison’s in the United States comes from one U.S. firm and oneCanadian firm. A British firm has a small share of the U.S. market but is at a disadvantagebecause of its distance. The British firm’s marketing and transportation costs in the U.S. marketare relatively high. Given that one-third of the company sales are exported to the United Kingdom and invoices forexports are in US dollars, the demand for its exports is highly sensitive to the value of the Britishpound.

- Suppose that in the market for cell phone service the number of competitors has dwindled until D & C Romer Net and Spa T. Wireless have become the only providers left in the nation. Seeking to boost their profits, the two companies secretly agree to a coordinated increase in their prices for cell phone minutes. This practice is known as a Nash equilibrium. O tying. collusion. antitrust. predatory pricing.1. Best responses in a Cournot Oligopoly Firm A and Firm B sell identical goods Total market demand for the good is: The inverse demand function is therefore 1 P(QM) = 780 -Q=780 -0.02222QM 45 QM is total market production (i.e., combined production of firm's A and B.

The store costs $200 per week andthe marginal cost is $10 per unit of output in addition to the fixed cost of the store. Hint: Mathematically this problem can be solved just like a monopoly problem. (a) If the typical the demand facing each individual firm is QD = 40−P eachweek, what price will a typical firm in this industry charge? (Hint: IfQD = 40 − P then P = 40 − QD and MR = 40 − 2QD).

(c) Will new firms enter the market if demand stays the same and new firmsface the same demand and have the same costs? (d) In general, what is the long run profit of an average firm in a monopolistically competitive market.
