Suppose the Boston to Philadelphia airline route is serviced by three airlines – US Airways (Firm A) and JetBlue (Firm B) and Continental (Firm C). The demand for airline travel between these two cities is Q = 150 – p. The cost function is C(Q) = 30Q. The cost function is the same for all three airlines. Assume that the three airlines are making investments in airline capacity. In other words, they are simultaneously choosing quantity. (Cournot Competition) Derive US Airways’ residual demand function given JetBlue’s output, qB, and Continental’s output, qC. What is the Marginal Revenue for US Airways? Derive US Airways reaction function Derive the market equilibrium quantity, Q*, price, p*, and Profit.
please solve the question completely. Suppose an industry consists of two firms that compete in prices. Each firm produces one product. The demand for each product is as follows: q1 = 25 - 5p1 + 2p2 q2 = 25 - 5p2 + 2p1 The cost functions are C(qi) = 2 + qi for i = 1; 2. (a) Are the products produced by these firms homogenous or differentiated? (b) Find the best response function for each rm. (c) How does the price firm 1 sets change with its belief about the price of its competitor\'s product? (d) What are the Nash equilibrium prices? (e) What is the percentage markup of price over marginal cost here (this is called the Lerner index)? Do the firms have market power? Why does the Bertrand paradox of zero variable duopoly profits apply here? (f) Suppose the firms merged. What is the new price of products 1 and 2? (g) Explain intuitively why the price is higher under monopoly than under Bertrand duopoly? (h) Are total monopoly profits higher or lower than the sum of Bertrand duopoly…
JointJuice produces a prepackaged joint support supplement for relief of joint pain with 180 tablets per bottle and operates in a perfectly competitive market. Basically, all the firms in this competitive market have technologies (production and cost conditions) that are the same as JointJuice’s. Suppose JointJuice’s total cost function is given by the following where q is JointJuice’s quantity of packages per day: C(q) = 250 + 6q + 0.1q^2 The market demand function for the output in this market is given by: Q = 1848 - 2P If there are 20 identical firms in this industry, find the market equilibrium price for the prepackaged supplements. Calculate JointJuice’s optimal output level and profits given the market price for the product. If JointJuice is typical of the firms in this industry calculate the firm’s long-run equilibrium output, price, and profit level. Suppose the situation changes. JointJuice has its plant in Portland Oregon. The local government passes a new tax on…
There are two identical firms in an industry, 1 and 2, each with cost function , i = 1,2. The industry demand curve is P = 100 − 5X where industry output, X, is the sum of the two firms’ outputs (X1 + X2). (a) If each firm makes its output decisions on the assumption that the other will not react to its choices (the Cournot assumption), what is the equilibrium output for each firm? What is the equilibrium price? (b) Suppose that each firm takes it in turn to choose its level of output, on the assumption that the other’s output level is fixed. Would the process of adjustment be stable? (c) Suppose that firm 1 introduces a cost-saving innovation, so that its cost curve becomes C1 = 8X1. Firm 2’s cost curve and the industry demand curve are unchanged. What happens to the equilibrium quantity produced by each firm and to market price?
A homogeneous product duopoly faces a market demand function given by p = 300 - 3Q,where Q = q1 + q2. Both firms have constant marginal cost MC = 100. What is the Bertrand equilibrium price and quantity in this market?
Two firms compete in a market to sell a homogeneous product with inverse demand function P = 1,500 – 10Q. Each firm produces at a constant marginal cost of RM20 and has no fixed costs. Use this information to compare the output levels and profits in settings characterized by Cournot, Stackelberg and Bertrand.
The market for a standard-sized cardboard container consists of two firms: CompositeBox and Fiberboard. As the manager of CompositeBox, you enjoy a patented technology that permits your company to produce boxes faster and at a lower cost than Fiberboard. You use this advantage to be the first to choose its profit-maximizing output level in the market. The inverse demand function for boxes is P = 1,200 − 6Q, CompositeBox’s costs are CC(QC) = 60QC, and Fiberboard’s costs are CF(QF) = 120QF. Ignoring antitrust considerations, would it be profitable for your firm to merge with Fiberboard? If not, explain why not; if so, put together an offer that would permit you to profitably complete the merger
Suppose three firms compete in a homogeneous-product Cournot industry. The market elasticity of demand for the product is −2, and each firm’s marginal cost of production is $50. What is the profit-maximizing equilibrium price?
Pizza Hut and Dominoís are considering to open a shop in a new shopping precinct in Burwood. Suppose both charge $10 for a pizza (price competition is ignored here), and the aggregate local demand for pizza at this price is Q: If both Örms open a shop in the shopping precinct, Q is shared equally between the two shops. On the other hand, if there is only one pizza shop in the shopping precinct, the total demand Q goes to that shop. The total cost function for Pizza Hut is TC P(Q) = 5Q + 6000 and the total cost function for Dominos is TCD(Q) = 5Q+ 6000: Each has two strategies: Open a shop or Not, and they make their decisions simultaneously. The payoff is zero for a firm that does not open a shop in the shopping precinct. Suppose Q= 3000: Construct a 2 X 2 payoff matrix for this entry game between Pizza Hut and Dominoís and Önd the NE of the game. Suppose Q = 2000:Construct a 2x2 payoff matrix for this entry game between Pizza Hut and Dominoís and Önd the NE of the game.…
Additional Problem 3: Assume two companies (C and D) are Cournot duopolists that produce identical products. Demand for the products is given by the following linear demand function: ? = 600 − ?C − ?D where ?C and ?D are the quantities sold by the respective firms and P is the price. Total cost functions for the two companies are ??C= 25,000 +100?C 2 ??D = 20,000 + 125?D c. Determine the equilibrium price and quantities sold by each firm. d.Determine the profits for the market as well as eachfirm.

All three firms have identical Cost functions: TC = 1200 - 95q + 2q2.i) Given that the firms are able to collude, what is the equilibrium market price and output?ii) If all of the firms cheat and each increases output by two units, what would be the new equilibrium price and the impact on an individual firm’s profits?
Consider a market structure comprising two identical firms (A and B), each with the cost function given by: Ci = 30Qi , where Qi for i = {A, B} is output produced by each firm. Market demand is given by: P = 210 − 1.5Q, where Q = QA + QB (i) Find Cournot equilibrium. (ii) What will be the outcome if the firms decide to collude? Compare it with the results under the Cournot equilibrium.
