Game theory Nash equilibrium 1. A slight increase in the marginal cost of a firm definitely leads to a reduction in its output if the firm competes in the: A. Sweezy fashion. B. Cournot fashion. C. Bertrand fashion. D. Cournot fashion and Bertrand fashion. Please explain your answer 2. The market for widgets consists of two firms that produce identical products. Competition in the market is such that each of the firms independently produces a quantity of output, and these quantities are then sold in the market at a price that is determined by the total amount produced by the two firms. Firm 2 is known to have a cost advantage over firm 1. A recent study found that the (inverse) market demand curve faced by the two firms is P = 280 2(Q1 + Q2), and costs are C1(Q1) = 3Q1 and C2(Q2) = 2Q2. a. Determine the marginal revenue for each firm. b. Determine the reaction function for each firm
