3. Consider a duopoly with a demand curve given by P = a-bQ, where a and b are positive constants and Q is the total production by the two firms. Firms sell identical goods and have an identical constant marginal cost of production c. Fixed costs are equal to zero. We assume firms choose quantities simultaneously (Cournot competition). a. Obtain the first order condition of profit maximization for each firm. Use graphical analysis and economic intuition to explain what they represent. b. Obtain the profit maximizing quantity for each firm. Explain what they represent using game theory concepts c. Demonstrate using relevant graphical analysis and economic intuition that the results obtained in b are not a Pareto Optimum for the firms involved. d. How would the graphical analysis in part a change if Firm A had a fixed cost of production

Consider a duopoly market with 2 firms. Aggregate demand in this market is given by Q = 500 – P, where P is the price on the market. Q is total market output, i.e., Q = QA + QB, where QA is the output by Firm A and QB is the output by Firm B. For both firms, marginal cost is given by MCi = 20, i=A,B. Assume the firms compete a la Cournot. 1. What are the equilibrium quantities? 2. What is the total quantity supplied on this market? 3. What is the equilibrium price in this market?

4. Consider a homogeneous good duopoly with linear demand P(Q) = 12-Q, where Q is the total industry output, and constant marginal costs c=3. a. Suppose that firms simultaneously set quantities. Determine the equilibrium price, quantities, profits, and welfare.b. The firms consider merging although their production costs are not affected. Determine the solution to this problem. Is such a merger profitable? What are the welfare effects of this merger?c. Consider the possibility of firm entry after the merger (the entrant produces at marginal costs c=3 and has entry cost F). Suppose first that the merger is not efficiency-enhancing. Analyze such a market and comment on your result (depending on the entry cost F).
