Use the following table to answer the question below, noting the first number represents the payoff for player 1 and the second number represents the payoff for player 2. How many Nash Equilibria are present in this game? Player 2 Player 1 Left Centre Right Top (5.8 , 8.8) ( 3.3 , 4.3) (5.8 , 8.8 ) Centre ( 3.9, 4.7) ( 11.4 , 12.7) ( 1.4, 3.5 ) Bottom (5.8 , 8.8) ( 2.1, 47) ( 5.8 , 8.8) Answer: A market is at long-run equilibrium of P* = $128 and Q' = 31000 units. All firms in the market are identical, and each has a marginal cost curve of P = 4 + 2q, where q is the quantity produced by that firm only. How many firms exist in the market? Answer: Suppose that in the cigarette market in Paris, the demand curve is given by P = 11-Q, and the supply curve is given by P = 30, where Q represents millions of cigarettes. Further, suppose that smoking cigarettes produces an additional cost for Paris residents valued at $2 per million cigarettes. What is the socially optimal number of cigarettes consumed (in millions)
