2. Consider the following Stackelberg model with 2 firms. Let firm 1 be the incumbent and firm 2 the potential market entrant. • Incumbent firm faces a marginal cost of c = 4. • Potential entrant faces a marginal cost of c= 2 and entry cost F. • The market demand curve is P = 12 - Q. • The incumbent decides q first, then the potential entrant decides q2. 92 = 0 if firm 2 %3D decides not to enter. (a) What is the incumbent firm's monopoly price, quantity and profit? (b) Suppose F = 0. What are the equilibrium quantities and profits for both firms? What is the equilibrium price? (c) For which values of F is firm 2's entry into the market blockaded, accommodated or preyed upon? When firm 2's entry is preyed upon, which quantity, q1, does firm 1 use to dissuade firm 2 from entering? (d) Suppose that now F = 0 naturally. That is, there no is barrier to entry for firm 2. However, now suppose the firm 1 can spend a on creating artificial barriers to entry. For example, a may be the cost of litigation over extending expiring patents. Let F(x) = a x x be the fixed entry cost for firm 2 when firm 1 spends r. For which values of o does firm 1 prevent firm 2's entry?

Consider a Cournot model of a market with of two firms with differentiated products. Firm 1 has Cournot best response function qi(q2) = (150-3q2)/10 and has constant marginal cost of 100. Firm 2 has Cournot best response function q2(q) = (100-2q1)/3 and has constant marginal cost of 50. What are the firms' marginal revenue functions? 20. Firm I's Cournot equilibrium output level is 21. Firm 1's Cournot equilibrium output level is
Consider a duopoly market, where two firms sell differentiated products, which are imperfect substitutes. The market can be modelled as a static price competition game, similar to a linear city model. The two firms choose prices p, and p2 simultaneously. The derived demand functions for the two firms are: D1 (P1, P2) = SG+P1)and D2 (P1, P2)= S(;+-P2), where S > 0 and the parameter t > 0 measures the 2t 2t degree of product differentiation. Both firms have constant marginal cost c> 0 for production. (a) Derive the Nash equilibrium of this game, including the prices, outputs and profit of the two firms. (b) From the demand functions, qi= D¡ (p; , p¡ )= SG+P), derive the residual inverse demand functions: p; = P; (qi , p¡) (work out: P; (qi , P;)). Show that for t > 0, P;(qi , P;) is downward 2t aPi (qi ,Pj) . sloping, i.e., c, i.e., firm į has market power. %3D (c) Calculate the limits of the equilibrium prices and profit as t → 0 ?

QUESTION 13 Consider a market where two firms (1 and 2) produce differentiated goods and compete in prices. The demand for firm 1 is given by D₁(P₁, P2) = 140 - 2p1 + P2 and demand for firm 2's product is D2 (P1, P2) 140 - 2p2 + P1 Both firms have a constant marginal cost of 20. What is the Nash equilibrium price of firm 1? (Only give a full number; if necessary, round to the lower integer; no dollar sign.)
5. Two firms compete repeatedly in a market of homogeneous goods. Each year, the firms can choose to charge a low or high price. The following payoff table summarizes their payoffs each year. The competition goes on indefinitely. Let 5 E (0, 1) denote the discount factor for both firms. Firm 2 Low High Low 0, 0 5, 0 Firm 1 High 0, 5 4, 4 Consider an n-period punishment trigger strategy s: • Play "High price" in the first stage. • In stage t> 2, if some player deviated to "Low price" in the last period when he is supposed to play "High price", then play "Low price" for n periods and then restart the game. In other words, after playing "Low price" for n periods, play "High price" in the next stage as if it is the first stage of the game. Otherwise, play "High price". Find the necessary and sufficient condition on & for (s, s) to be an SPE. A sufficiently simplified inequality will do.
16-1. Two equal sized newspaper have an overlap in circulation of 10% (10% of the subscribers subscribe to both newspaper). Advertisers are willing to pay $10 to advertise in one newspaper but only $19 to advertise in both , because they’re are unwilling to pay twice to reach the same subscribers. What’s the likely bargaining negotiation outcome if the advertisers bargain by telling each newspaper that they’re going to reach an agreement with the other newspaper so the gains to reaching agreement are only $9? Suppose the two newspaper merge. What is the likely post merger bargaining outcome?
Consider an industry with 6 identical firms, each facing a demand Q = 30,000 x [1/6 – 1/20 (p -p )), where Q is the output level by the firm, p is the price charged by the firm and p is the average price in the industry. Suppose each firm has a fixed cost 7500 and a marginal cost 35. What is p in a symmetric equilibrium when there is no entry or exit of any firm? (Round your answer to the nearest integer.) Your Answer:
8)Consider a market in which 5 companies operate, whose marginal and average costs are equal to c. The demand function is given by P(Q)= 1-Q, where P is the price and Q indicates the total quantity. Assume that companies compete with Cournot in choosing production levels. Assume that the game is repeated an infinite number of periods, that companies adopt trigger strategies and that the punishment is represented by Nash Reversion. 1)What is the value of the discount factor that allows companies to sustain tacit collusion in a balanced situation? 2) Assume now that companies are able to discover the defection of a rival company with K periods of delay. What do you think the effect on the sustainability of collusion can be? 3) Do you think that in this market collusion would be more easily sustainable if the companies compete with Bertrand? 4) If in a price-competitive market (Bertrand) N symmetrical companies operate, what would be the critical value of the discount factor that would…
