8. There are several identical firms in a market. The cost function of firm i is q? +q, where qi is the output of this firm, and q is the sum of other firms' output. The market demand is q(p) = - p. We assume that all firms are Cournot oligopolists, and the market is free entry. In equilibrium the number of firms in the market is A. 5 C. 3 D. 2 B. 4

Coke and Pepsi dominate the cola market. Suppose that the marginal cost of making cola is $2. Assume also that the demand for cola is given by the following table: Price $8 7 6 5 4 3 2 1 Quantity 5 cans 6 7 8 9 10 11 12 Suppose Coke and Pepsi both supply cola. They form a cartel and agree to cooperate on how much soda to produce. In this cartel case, how many bottles of cola would be sold? Type your answer...

please explain in steps

6. Suppose that identical duopoly firms have constant marginal costs of $10 per unit. Firm 1 faces a demand function of q1 = 100– 2p1+p2, where q1 is Firm l's output, pi is Firm l's price, and p2 is Firm 2's price. Similarly, the demand Firm 2 faces is q2 = 100– 2p2+P1. Solve for the NE.

1. Consider a Cournot duopoly with the inverse demand P = 260 - 2Q. Two firms compete choosing their quantities. Both firms have constant. marginal and average cost MC = AC = 20. a. Find each firm's best response function. b. Find the Cournot equilibrium. c. Plot the best response curves and illustrate the equilibrium point.

Plz solve this.

1. marginal costs e, = c, = c, = 20. The inverse demand function is given by P = 100 - Q. where Q = q, + 4: + 93- Consider a market with three firms (i - 1, 2, 3). which have identical a) Identify the reaction functions for each firm and compute the Cournot equilibrium, i.e., the market price and quantity. b) What happens to the market price if all three firms merge compared to part (a)?

2.- Each of two firms, firms 1 and 2, has a cost function C(q) = 1 2 q; the demand function for the firms' output is Q = 1.5-p, where Q is the total output. Firms compete in prices. That is, firms choose simultaneously what price they charge. Consumers will buy from the firm offering the lowest price. In case of tying, firms split equally the demand at the (common) price. The firm that charges the higher price sells nothing. (Bertrand model.) (a) Formally argue that there could be no equilibrium in prices other than p1 = p2 = 1 2. (b) Solve the same problem, but this time assuming that firms compete in quantities.Now, suppose that firm 1 has a capacity constraint of 1/3. That is, no matter what demand it gets, it can serve at most 1/3 units. Suppose that these units are served to the consumers who are willing to pay the most. Thus, even if it sets a price above that of firm 1, firm 2 may be able to sell some output. (c) Obtain the (residual) demand of firm 2 (as a function of its own…
