A homogenous good industry consists of two identical firms (firm 1 and firm 2). Both firms have a constant average total cost and marginal cost of $4 per unit. The demand curve is given by P = 10 – Q. Suppose the two firms choose their quantities simultaneously as in the Cournot model.

(1) Find and plot each firm’s best-response curve. (Be sure to clearly label your curves, axes and intercepts.)

(2) Find each firm’s quantity and profit in the Nash equilibrium.

Consider a Cournot model with two firms, firm 1 and firm 2, producing quantities q1 and q2, respectively. Suppose the inverse market demand function is: P = 450 – Q where Q denotes the total quantity supplied on the market. Also, each firm i = 1,2 has a total cost function c(qi) = 30qi. a) What is the Nash equilibrium of this Cournot game ? What is the market prices ? Compute each firm’s profit and the industry profit. b)...

1. In a given industry located in the town of Teahupo’o all firms have access to the same technology. The cost curve for Tikei’s firm is: TC = 3q2, where q is the output of Tikei’s firm. Marginal cost is MC = 6q. Initially, there are 60 firms in the industry (Tikei’s firm + Mako’s firm + Moana’s firm + Vanea’s firm + 56 other firms). The 60 firms in the industry are identical in every way. a) Find the...

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...

Two firms, A and B, are Cournot competitors facing the inverse market demand P = 5 - 0.001Q, where Q = qA + qB. Each firm has the same total cost function Ci = 2qi , i = A, B. a. (8) Write out the profit function of firm A, then derive the best response functions for A and B. (You only need to derive one best response function because A and B are identical.) Carefully graph the best response...
