Two firms, Incumbent & Entrant, can produce the same good. The market demand for the good is given by P = 180 – Q, where P is the market price and Q is the market quantity demanded. The firms must pay w = 45 per unit of output for labour and r = 45 per unit of output for capital (one unit of capital is used per unit of output), but Incumbent may choose capacity KI units of capital before Entrant decides whether to enter the market. Suppose firms each have fixed costs FI =600, FE=500. Incumbent chooses (as a Stackelberg leader) capacity KI equal to the monopoly profit- maximizing quantity. When you answer the following questions, show your work. a. Would Incumbent be able to prevent entry by choosing capacity KI equal to the monopoly profit-maximizing quantity? Explain. b. What is the Incumbent’s equilibrium choice of capacity KI in this Dixit game? c. Does the Incumbent’s choice of capacity KI in part (b) qualify as predatory conduct (here, limit output)? Explain.

Suppose that there are two firms in the market. The market demand is given by P=220 - 2Q, where Q is the total output (Q=Q1+Q2). Each firm has an identical cost function, TCi=8Qi, i=1, 2. Consider the collusion, in which they decide the output level together to maximize the joint profit. If they divide the production into half, then each firm should produce Qi= _______ units in order to maximize the joint profit.
Two firms, Firm 1 and Firm 2, compete by simultaneously choosing prices. Both firms sell an identical product for which each of 100 consumers has a maximum willingness to pay of $40. Each consumer will buy at most 1 unit, and will buy it from whichever firm charges the lowest price. If both firms set the same price, they share the market equally. Costs are given by C; (qi) = 16q¡ . Because of government regulation, firms can only choose prices which are integer numbers, and they cannot price above $40. Could you help me with these questions? a) If Firm 1 chooses Pi price? = 32, Firm 2's best response is to set what b) If Firm 2 chooses the price determined in the previous question, Firm 1's best response is to choose what price? c) If Firm 1 chooses p₁ = 9, Firm 2's best response is a range of prices. What is the lowest price in this range?
Two firms sells an identical product. The demand function for each firm is given: Q = 20 - P, where Q = q1 + q2 is the market demand and P is the price. The cost function for reach firm is given: TCi = 10 + 2qi for i = 1, 2. a) If these two firms collude and they want to maximize their combined profit, how much are the market equilibrium quantity and price? b) If these two firms decide their production simultaneously, how much does each firm produce? What is the market equilibrium price? c) If Firm 1 is a leader who decides the production level first and Firm 2 is a follower, how much does each firm produce? What is the market equilibrium price?
Consider a "Betrand price competition model" between two profit maximizing widget producers say A and B. The marginal cost of producing a widget is 4 for each producer. Each widget producer has a capacity constraint to produce only 5 widgets. There are 8 identical individuals who demand 1 widget only, and individuals value each widget at 6. If the firms are maximizing profits, then which of the following statement is true: a) Firm A and Firm B will charge 4 b) Firm A and Firm B will charge 6 c) Firm A and Firm B will charge greater than or equal to 5 d) None of the options are correct. Explain clearly.
Two firms, Firm 1 and Firm 2, compete by simultaneously choosing prices. Both firms sell an identical product for which each of 100 consumers has a maximum willingness to pay of $40. Each consumer will buy at most 1 unit, and will buy it from whichever firm charges the lowest price. If both firms set the same price, they share the market equally. Costs are given by c; (q) = 16q;. Because of government regulation, firms can only choose prices which are integer numbers, and they cannot price above $40. Answer the following: a) If Firm 1 chooses pi = 32, Firm 2's best response is to set what price? b) If Firm 2 chooses the price determined in the previous question, Firm 1's best response is to choose what price? c) If Firm 1 chooses pi = 9, Firm 2's best response is a range of prices. What is the lowest price in this range? d) Now suppose both firms are capacity-constrained: Firm 1 can produce at most 42 units, and Firm 2 can produce at most 44 units. If firms set different prices,…
Two firms produce a homogeneous good and compete in price. Prices can only take integer values. The demand curve is Q = 6 p, where p denotes the lower of the two prices. The lower - priced firm meets all the market demand. If the two firms post the same price p, each one gets half the market demand at that price, i. e., each gets (6p)/2. Production cost is zero.a) Show that the best response to your rival posting a price of 6 is to post the monopoly price of 3. What is the best response against a rival's price of 4? of 5?
Two firms sell an identical product in a market by setting prices simultaneously. Consumers buy from the firm that offers the lower price; if the prices are identical, the firms split the demand. If ? is the lowest price (in dollars), aggregate demand is ? = 250 − ?. Suppose prices can only be set in increments of 1 cent. (a) Suppose Firm 1 and Firm 2 have limited production capacities of 40 units each. The marginal cost of firm 1 is $35 and the marginal cost of firm 2 is $25. If Firm 1 believes that Firm 2 will set a price of $30, what price should Firm 1 set? Show your work. (Assume efficient rationing while calculating firm’s residual demand.) (b) Ignore the information in part (a). Suppose each firm has unlimited capacity, but that the marginal costs of Firm 1 and Firm 2 are $40 and $150 respectively. Do ?1 = 149.99 and ?2 = 150 satisfy the requirements of a Nash equilibrium? Explain why. You must explain why a strategy is a best response or not to the other strategy.

Consider a market for crude oil production. There are two firms in the market. The marginal cost of firm 1 is 20, while that of firm 2 is 20. The marginal cost is assumed to be constant. The inverse demand for crude oil is P(Q)=200-Q, where Q is the total production in the market. These two firms are engaging in Cournot competition. Find the production quantity of firm 1 in Nash equilibrium. If necessary, round off two decimal places and answer up to one decimal place.
Consider a single country and a single good. The demand curve for this good is given by QD = 144 - 4P. Thereare two firms serving the market: Firm A and Firm B, where Firm A has a marginal cost of $20 and Firm B hasa marginal cost of $16. There are no fixed costs incurred by either firm. Firm A produces 16 units and firm B produces 32 units. The equilibrium price is $24. Total Profit for Firm A = $64 Total Profit for Firm B = $256 Assume that these firms compete in Cournot fashion. What is the consumer surplus? Show your work.
suppose there are two firms that compete in prices, say firms 1 and 2, but that the firms produce differentiated products. Suppose that the demand for firm 1 is q1(p1,p2)=10-2p1+p2 and the demand for firm 2 is q2(p2,p1)=10-2p2+p1. Also, assume that firm 1 has a constant marginal cost of c1 = 2 and firm 2 has a constant marginal cost of c2 = 3. i. Solve for the Bertrand equilibrium in prices. ii. Now, suppose firms 1 and 2 merge and firm 1 will operate both firms and they will split the resulting profits equally. Will both firms agree to this merger or do they prefer the Bertrand outcome?
According to an article in China Daily, China recently accelerated its plan to privatize tens of thousandsof state-owned firms. Imagine that you are an aide to a senator on the Foreign RelationsCommittee of the U.S. Senate, and you have been asked to help the committee determine the priceand quantity that will prevail when competitive forces are allowed to equilibrate the market. The bestestimates of the market demand and supply for the good (in U.S. dollar equivalent prices) are given byQd = 10 − 2P and Qs = 2 + 2P, respectively. Determine the competitive equilibrium price.
