PROBLEM VIII. Suppose that, in a market of a certain good, there are two firms that are engaged in an infinitely repeated Cournot competition. In each period, the inverse demand function is given by P(Q) = 200 − 4Q, where Q is the total supply of the good. Firm i (i = 1, 2) has the same cost function C(qi) = 8qi and the same discount factor δ, where 0 < δ < 1.

Q20. What is the Cournot equilibrium profit for each firm? (a) 861. (b) 1422. (c) 968. (d) 1024. (e) 798.

Q21. What is the collusive profit for each firm? (a) 1152. (b) 1328. (c) 1224. (d) 1720. (e) 1352.

Q22. What is the defection profit for a deviating firm? (a) 1664. (b) 921. (c) 1082. (d) 1752. (e) 1296.

Problem III. Suppose that, in a market of a certain good, there are firms that are engaged in a Cournot competition. The inverse demand function is given by P(Q) = 120 − 6Q, where Q is the total supply of the good. All firms have the same cost function C(qi) = 30qi + 50. Q7. What is the Cournot equilibrium price of the good when there are N firms in the market? (a) (30N + 200)/(N + 1) 2 (b)...

Suppose the market for a certain good has an inverse demand of ? = 180 − ?. The aggregate private marginal cost for the firms that produce the good is ?? = 20 + ?. However, production of the good also creates pollution with an external marginal cost of ??? = 10 + ?/2. If this is a perfectly competitive market with no regulation, what is the equilibrium price and quantity produced? Suppose instead that the market is a monopoly....

Suppose there are two firms operating in a market. The firms produce identical products, and the total cost for each firm is given by C = 10qi, i = 1,2, where qi is the quantity of output produced by firm i. Therefore the marginal cost for each firm is constant at MC = 10. Also, the market demand is given by P = 106 –2Q, where Q= q1 + q2 is the total industry output. The following formulas will be...

Consider a market served by two firms: firm A and firm B. Demand for the good is given (in inverse form) by P(Q)=250−Q, where Q is total quantity in the market (and is the sum of firm A's output, qA, and firm B's output, qB) and P is the price of the good. Each firm has a cost function of c(q)=10.00q, which implies marginal cost of $10.00 for each firm, and the goods sold by firms A and B are...

Suppose there are only two firms, firm1 and firm2, in the market. They both choose a quantity to produce simultaneously. The market price is determined by the market demand: p =130-(Q1+Q2) where Q1 is the output quantity of firm1 and Q2 is the output quantity of firm2. Firm1’s total cost of production is 10Q1 and firm2’s total cost of production is 10Q2. That is, both firms have a constant marginal cost of 10. Task 1. What’s firm 1’s best response...

Suppose two firms, "A" and "B," form a duopoly in the market for a special type of computer chip. Each firm has a constant marginal cost of $2. The daily market demand for this chip is given by the following equation: P = 8 – 0.005 Q = 8 – 0.005 (qA+qB). a. Find an expression for firm #A's revenue, as a function of its own quantity and firm B’s quantity: RevA(qA,qB). [Hint: By definition, RevA = P qA. Here,...
