Two firms compete by choosing price. Their demand functions are Q, = 200 - P, + P2 and Q2 = 200 + P, - P2, where P, and P, are the prices charged by each firm, respectively, and Q, and Q, are the resulting demands. Note that the demand for each good depends only on the difference in prices; if the two firms colluded and set the same price, they could make that price as high as they wanted, and earn infinite profits. Marginal costs are zero. Suppose the two firms set their prices at the same time. Find the resulting Nash equilibrium. What price will each firm charge, how much will it sell, and what will its profit be? (Hint: Maximize the profit of each firm with respect to its price.) Each firm will charge a price of $.

Two firms produce identical products at zero cost, and theycompete by setting prices. If each firm charges a low price,then both firms earn profits of zero. If each firm charges ahigh price, then each firm earns profits of £30. If one firmcharges a high price and the other firm charges a low price,the firm that charges the lower price earns profits of £50, andthe firm charging the higher price earns profits of zero. (a) Which oligopoly model best describes this situation?(b) Write this game in normal form.(c) Suppose the game is infinitely repeated.

6. Two firms, Firm 1 and Firm 2 and are competing in quantities. The demand they are facing is given by p=1-91-92, with p being the price of the good, and 9₁ and 92 the quantities produced by firm 1 and 2 respectively. The total cost of firm 1 is TC1 (91) = 9₁ and the one of firm 2 is TC₂ (92) = 292. (a) Find the Cournot equilibrium. (b) The government decides that it wants to make the market more competitive. As such it decides to offer to Firm 1 a license to become the leader in the market. The licence costs F, and if Firm 1 buys it, it will be allowed to choose its quantity before Firm 2. What is the maximum Firm 1 would be willing to pay for this license?
if two firms (firm A and firm B) are competing selling T-shirts, both at $12 per shirt, both have a quantity of 50 and both can produce a t-shirt at a cost of $2 per shirt both marginal and average. If both companies are competing directly against each other in prices, what will the new marginal price of company B will be? and what will be their profits? Also, how do you solve the equilibrium price in oligopolies?
Suppose that Market demand for golf balls is described by Q= 90-3p,Where Q is measured in kilos of balls. There are two firms that supply the market. Firm 1 can produce a kilo of balls at a constant unit cost of $15 whereas firm 2 has a constant unit cost equal to $10.a. suppose firms compete in quantities.

. The market for widgets consists of two firms that produce identical products. Competition in the market is such that each of the firms independently produces a quantity of output, and these quantities are then sold in the market at a price that is determined by the total amount produced by the two firms. Firm 2 is known to have a cost advantage over firm 1. A recent study found that the (inverse) market demand curve faced by the two firms is P = 280 – 2(Q1 + Q2), and costs are C1(Q1) = 3Q1 and C2(Q2) = 2Q2. a. Determine the marginal revenue for each firm. b. Determine the reaction function for each firm.

Price competition between firms, from the firms’ perspective, can be similar to the prisoners’ dilemma. The best outcome for all firms would be for all to charge a high price. However, if the other firms charge a high price, any individual firm has incentives to charge a low price and steal the market. Additionally, if any other firm chooses a low price, each firm should charge a low price too so that it doesn’t get priced out of the market. Explain how price-matching (firms announcing a policy where they match the lowest price a customer can find or will honor a competitor’s coupon) can help firms avoid the Nash equilibrium in which they all charge a low price. Is it misleading for a firm to advertise price-matching as being beneficial to consumers? (Hint: What outcomes of the game are ruled out by the price-matching policy? How does ruling out these outcomes change the game and the decision the firms face?)

Three firms compete in the style of Cournot. The inverse demand is P(Q) = a - Q. Scenario 1: All three firms have the same constant marginal cost MC = c. Scenario 2: Firm 1 has MC = 0.5c, Firm 2 has MC = c, and Firm 3 has MC = 1.5c. Assume that a > 3c. Which of the following is correct? (Price means the price in Nash equilibrium.) O Price in scenario 1> Price in scenario 2 O Price in scenario 2> Price in scenario 1 O Price in scenario 1 = Price in scenario 2 O Any of the first three options is possible depending on the value of a O Any of the first three options is possible depending on the value of a and c.
