0 Consider the following market of a homogeneous product, which has de- mand function: Q = 102 P. Each rm has a total cost function: 0 (92') = 2%- 1. Let n 6 {1,2,...} be the number of rms. For n > 2 the rm engage in Cournot competition. Let g, be the output of rm i, for i: 1, . . . , n, and Q = 2219',- be the total output. Write down the inverse demand function for the market. Calculate each rm's marginal cost 1110,. Dene each rm's best response function. Solve for the Nash equilibrium point, and calculate the market price P, output Q, and each rm's Lerner index L1,; E 1311310, . Show how these results change with parameter in and explain their economics meaning. 2. Use your results from part 1 to show for n > 00, the market share of rm i: 8,; E 95 E 0, and rm i's marginal revenue: 111R,- E d if\"? q\" E P (Q), and thus rm i tends to behave like a price taker, 9'2 and P(Q) > 1110,. Consequently, for n > 00, the market tends to be perfectly competitive. Use this result to calculate the perfectly competitive equilibrium price, and total output. The calculate Lerner index, consumer surplus, producer surplus, and social surplus under perfect competition. 3. Apply your result from part 1 to a monopoly market with the same demand and cost function. Calculate the monopoly price, and out- put. Then calculate the Lerner index, consumer surplus, producer surplus, and social surplus of the monopoly market. Calculate the monopoly deadweight loss (relative to perfect competition). 4. Use your result from Part 1 to calculate the consumer surplus and deadweight loss as a function of n, and show how they change with n, including their limits as n E 00. Explain the economics meanings of these results
