Assume that you observe two firms operating in a Bertrand oligopoly. The inverse demand function for the market is P = 200 – 2Q and each firm has the same cost function of C(Q) = 20Q. What is the level of production for each firm, market price, and profit of each firm? What would happen if both firms merge to form a single monopoly with a cost function of C(Q) = 20Q?

Problem 4. Three firms operate in an oligopoly market with inverse demand function given by D(Q)a Q, where Q- 1 42 +q3 and q, represents the quantity produced by firm i. Each firm has constant marginal cost of production c and no fixed cost, assume that 0<c<a. The firms compete in the market by choosing quantities in the following way. Firm 1, the industry leader, chooses gi20. Firms 2 and 3 both observe qi. Firm 2 then chooses q2 2...
1. Consider a market with inverse demand P(Q) = 100 Q and two firms with cost function C(q) = 20q. (A) Find the Stackelberg equilibrium outputs, price and total profits (with firm 1 as the leader). (B) Compare total profits, consumer surplus and social welfare under Stackelberg and Cournot (just say which is bigger). (C) Are the comparisons intuitively expected? 2. Consider the infinite repetition of the n-firm Bertrand game. Find the set of discount factors for which full collusion...
Two firms in an industry engaged in Bertrand competition. The industry inverse demand function is p = 40 - 2Q, and marginal cost is MC = 10 for both firms. No firm faces capacity constraints. Find the BertrandNash equilibrium (prices, quantities, profits consumer surplus, total surplus, herfindahl index and lerner index)
Consider a homogeneous-product Cournot oligopoly with four firms. Suppose that the inverse demand function is P(Q) = 64 – Q. Suppose that firms incur a constant marginal cost c = 4. Characterize the equilibrium of the game in which all firms simultaneously choose quantity. Suppose that firms 1 and 2 consider merging and that there are synergies leading to marginal costs cm < c. Characterize the new market equilibrium. At what level of cm are the two firms indifferent whether...
2*. Consider a market with two firms where the inverse demand function is given by p = 28 - 2q and where q = q1 + q2. Each firm has the total cost function c(qi) = 4qi, where i = {1,2}. a) Compare price level, quantities and profits in this market calculating the Cournot equilibrium and the Stackelberg equilibrium.

There are 2 firms faced in a Bertrand Oligopoly with demand curves as follows: For Firm A QA = 400 – 4PA + 2PB For Firm B QB = 240 – 3PB + 1.5 PA The marginal cost for both firms is Zero Find the Bertrand Reaction Function for Firm A and the Price for firm A, PA with respect to PB
Two firms figure out that the market inverse demand is P= 81 - Q. Each firm has the cost C(Q)= Q^2. 1. Find the marginal revenue for the individual firms. 2. What is the reaction function for each firm? 3.What is the equilibrium quantity? 4. What is the market price? 5. How much profit does each firm make? 6. In the long-run what do you expect to happen in a market with profits like this? Find the optimal production for...
Given the following inverse demand and cost function, answer the questions below: a) Suppose barriers to entry exist such that only one firm serves the market with no threat of entry. What will be the monopoly price, outcome, and profit? b) Suppose instead that perfect competition exists in this market. What will be the competitive price, market quantity Q, and competitive firm profit? c) Suppose two firms serve the market with no threat of entry. If the two firms compete...
