Firms A and B operate in a market with inverse demand given by p = 160 - (q_{A} + q_{B}) Their total cost functions are C_{A}(q_{A}) = q_{A} ^ 2 / 2 and C_{B}(q_{B}) = q_{B} ^ 2 / 2 , respectively. The firms compete in quantities (Cournot competition). Denote by q_{A} ^ C and q_{B} ^ C the Nash equilibrium quantities in this game. What are q_{A} ^ C and q_{B} ^ C Hint: Again, note that I gave you the total cost function for each firm, not the marginal costs. (a) q_{A} ^ C = 24 q_{B} ^ C = 24 (b) q_{A} ^ C = 60 q_{B} ^ C = 30 (c) q_{A} ^ C = 40 q_{B} ^ C = 40 (d) q_{A} ^ C = 20 q_{B} ^ C = 20 (e) q_{A} ^ C = 30 q_{B} ^ C = 30

Two firms who make identical products engage in Cournot competition. The inverse market demand curve is: P(Q) = 60 - 10Q, where Q=9₁ +92. The cost functions are C₁(9₁) 1091 and C₂ (92) : 592 for firms 1 and 2, respectively. Find the Nash equilibrium quantities for each firm. (a) 9₁ = = 1.5, 92 2 (b) q₁ = 92 = 2 (c) q₁ = 92 = 1.5 (d) 9₁ = 1.5, 92 = 3 (e) None of the above options is correct.

Consider two firms, referred to as firms 1 and 2, who compete in a market by choosing quantities produced and face the following inverse demand: P(Q) 10-20 Each firm has a marginal cost of production of $4.00. Suppose these firms collude by agreeing to produce quantities to maximize their joint profits. Firm 1 sticks to the agreement, but firm 2 does not. If firm 2 can secretly change its produced quantity, how much would it produce?

Consider a Cournot duopoly. The market demand function is P = 180 – 2(q₂ + q₂), where P is the market price, q₂ is the output produced by Firm 1 and q₂ is the output produced by Firm 2. The two firms have a constant marginal cost c = 30. What is the total output in this market? Round your answer to the nearest integer (e.g. 50)

Consider a market that is a Bertrand oligopoly with 5 firms in the market.  Each of these firms produce an identical product and each have the same cost function of C(Q) = 80Q.  The inverse market demand for this product is P = 2480 – 2Q. What is the equilibrium market price?

**Practice** Consider a market with three firms. Each firm has a different cost function. We assume C1(q1) = 7q1, C2(q2) = q2 + 1, and C3(q3) = 3q3.

please help me with the last question. Thank you

Can you show me the answer of question c and d? Thank you so much for your help

Suppose the inverse market demand for manufactures is P(Q) = A – Q, where P and Q denote price and total goods produced and the parameter A denotes the size of the domestic market. Suppose any firm has a cost function, c(q) = cq, where A > c. Suppose there are two firm in the market which produce q1 and q2, where Q = q1 + q 2                                                                                                                                                    a. Solve for the Cournot equilibrium levels of output (Q*), price (P*) and markups.                                                                                       b. What is the impact of an increase in market size, A, on Q*, P* and markups when there are two firms? Provide some intuition for these predictions.                                                                                                                                                                                                   c.…

Consider a duopoly where firms compete in prices and firms do not have any capacity constraints. Market demand is P(Q)=45-4Q, and each firm faces a marginal cost of $9 per unit. How much is each firm's total variable cost if firms equally divide the market at Nash equilibrium?
