4. Bertrand Competition (29 points) Consider a Betrand Model. The market demand is P=130-Q. Consumers only buy from the firm charging a lower price. If the two firms charge the same price. they share the market equally. The marginal cost for firm 1 is 10, and the marginal cost for firm 2 is also 10. There are no fixed costs. A. (5 points) Would any firm charge a price below 10 at the market equilibrium? Briefly explain your reason. B....

consider the standard Bertrand model of price competition. There are two firms that produce a homogenous good with the same constant marginal cost of c. a) Suppose that the rule for splitting up cunsumers when the prices are equal assigns all consumers to firm1 when both firms charge the same price. show that (p1,p2) =(c,c) is a Nash equilibrium and that no other pair of prices is a Nash equilibrium. b) Now, we assume that the Bertrand game in part...
usion (24 points) Two firms are playing a repeated Bertrand game infinitely, each with the same marginal cost 100. The market demand function is P-400-Q. The firm who charges the lower price wins the whole market. When both firms charge the same price, each gets 1/2 of the total market. I. Coll A. (6 points) What price will they choose in the stage (only one period) Nash equilibrium? What price will they choose if in the stage game (only one...
Consider a Bertrand duopoly in a market where demand is given by Q firm has constant marginal cost equal to 20 100 - P. Each (a) If the two firms formed a cartel, what would they do? How much profit would eaclh firm make? (6 marks) (b) Explain why the outcome in part (a) is not a Nash Equilibrium. Find the set of Nash Equilibria and explain why it/they constitute Nash equilibria. (6 marks) (c) Now suppose that instead of...
2.2 Bertrand Competition Which of the following statement is NOT true? In a market of duopoly firms competing in quantities, the equilibrium price is higher than the marginal cost of firms. In a market of duopoly firms competing in quantities, the equilibrium price is lower than the price charged by a monopoly firm. In a market of duopoly firms competing in prices, the more efficient firm survives and charges a price equals to its marginal cost. ) In a market...
Consider the following variation of the Bertrand competition model (e.g., price competition) discussed in class. Two firms, 1 and 2, are producing the same identical product. Firms compete in prices: Firm 1 choses pı, and Firm 2 choses p2. Given pı and p2, the individual demands of fhrms are: 10-pi pi 〈 p2 Pi P2 0 P1〈P2 Both firms have constant marginal costs of c. To sum up, the payoffs are as follows: 2 C 92 (P1, P2 Unlike the...
