Consider a market with an inverse demand Function p = 60-4*Q. There are two firms, an incumbent and an entrant. There is a constant variable cost of 6 and a unit capacity cost of 6. In the first stage, the incumbent chooses capacity. In the second stage, the entrant decides whether or not to enter and all active firms choose quantities (where the entrant also has to simultaneously choose its capacity in the second stage, if it enters). a. For a capacity of 5 units, what is the best response function of the incumbent in the second period? b. What is the Cournot-Nash equilibrium of the second stage if the incumbent chose a capacity of 5 units in the first stage conditional on the entrant entering? c. For a capacity of an arbitrary k units, what is the best response function of the incumbent? d. What is the Cournot-Nash equilibrium of the second stage if the incumbent chose a capacity of k units in the first stage conditional on the entrant entering? e. Solve for the subgame perfect equilibrium of the game when the entry costs are 25. f. Solve for the subgame perfect equilibrium of the game when the entry costs are 64.

A large number of firms enter the Swedish market for the game Padel. For simplicity assume that they all act as price takers and let the cost function for each of them be given by C(q)=1000+0.4*q² where q is the number of customers served. a) In the long run free entry should drive profit to zero. At this point p=MC=ATC. Intuitively why is this the case? b) The condition in c) implies that in a free entry equilibrium with firms that have the same cost function each firm's production will be given by the lowest point in the average total cost curve. How much does each firm produce in the free entry equilibrium? What is price in this equilibrium? (Hint: You can either differentiate the expression for average cost to determine its minimum or you can look for the minimum point using your graph in b). c) Assume that overall demand is given by Q-1200-2*P. How many firms will there be in equilibrium?
The demand for home firm product is given by the inverse demand function: P = 120 −QD. The company’s costs are: T C = 20Q+ 200 and MC = $20.2. Suppose the home country open up to free trade and a foreign competitor enters the market. Assume thatthe foreign firm has the same cost structure as the home firm (the monopoly from the previous question).A) Derive the best response function for each firm (h-home and f-foreign)B) Find each firms’ output, the home market price, and each firms’ profit from the home market
Consider a market where two firms produce the same product, and compete by choosing the price to charge consumers. There are no capacity constraints and no fixed costs. Consumers purchase from the firm that charges the lowest price, Pmin Aggregate demand is given by Q(Pmin) = 600 – 30pmin. Both firms have marginal costs of c = 15. What is the aggregate quantity produced in this market? And what price do consumers pay? (a) p₁ = = 15, p2 = 20, Q = 150 (b) P1 = P2 = 15, Q = 150 (c) P₁ = P₂ = 20, Q = 0 (d) p₁ = 10, P2 = 15, Q = 300 (e) None of the above options is correct.
Suppose the airline industry consists of only two airlines, Jumbo jet and Kenya airways. Let the two firms have identical costs C(Q) = 40Q, where i = 1,2. Assume that the demand curve for the industry is given by P=100-Q
An upstream firm (U) sells an input to a downstream firm (D) which resells it to consumers. The marginal cost of U is 4. Each unit is sold by U to D at a transfer price r. Requirement final is p = 12 - y. a) Suppose U and D are separate firms. Find r, y and p. b) Suppose U and D are one integrated firm. Find p and y. c) Suppose the firms are not integrated, but firm U uses a two-part tariff: it requires payment of r for each unit sold to D; in addition, it requires payment lump sum of T. Find the value of r that U will choose. Find the minimum and maximum values by T. d) Suppose the firms are not integrated, but U imposes a resale price control on firm D. Find the value of r that U will choose, and the constraint that it will impose on the price final p

Demand is assumed to be unit-elastic: X(p) = 1/p. There are m ≥ b2 firms operating in the market with constant marginal cost levels c1 ≤ c2 ≤ ……. ≤ cm. They engage in Cournot competition. a. Show that the equilibrium price implies Lerner indexes Where si is the market share of firm i. b. Using the equilibrium price, show that the profit of firm i is equal to (si)2. c. Show that the industry profit is equal to the Herfindahl index H = Σi(si)2. d. What is the effect of a specific taxt on equilibrium price? How does this tax affect the industry profit and the Herfindahl index?
(b) Consider two firms, 1 and 2 , operating in a monopolistic competitive market. The cost functions of the firms are: TC_(1)=20+20 Q and TC_(2)=80+80Q, respectively. Would it be rational for both firms to compete in the world market, given the market demand curve of Q=100-P, and they have to bear a trade cost of $30 per unit? Explain with the help of a diagram. please give answer with compleete steps and diagram.
**Practice**
There are two firms, Firm 1 and Firm 2. The two firms’ products are viewed as identical by most consumers. The relevant cost functions are C(Q1) = 10 + 4Q1 and C(Q2) = 12 + 16Q2, and the market demand curve for product is given by P = 50 – 4Q. Instructions: Use no decimals. Use the average cost to calculate monopoly profits. Do not round values if used to complete other calculations. Complete the following table.
