.. Two firms compete in price in a market for infinite periods. In this market, there are N consumers; each buys one unit per period if the price does not exceed $10 and nothing otherwise. Consumers buy from the firm selling at a lower price. In case both firms charge the same price, assume N/2 consumers buy from each firm. Assume zero production cost for both firms. A possible strategy that may support the collusive equilibrium is: Announce a price of $10 if the equilibrium price has always been $10; otherwise, announce the price as in Nash equilibrium of the one-shot Bertrand game. 1.a Let 6 be the discount factor.

Firm 1 and firm 2 compete with each other by choosing quantities. The market demand is given by P(Q) = ( 300 − Q, if Q < 300) (0, otherwise), where Q = q1 + q2. Firm 1 has a cost function C1(q1) = 40q1, and firm 2 has a cost function C2(q2) = 50q2. Answer the following questions. 1. Assume the game lasts only one period. Compute the equilibrium price, quantities and profits for both firms. 2. If firm 1 becomes the monopolist on this market, what quantities will firm 1 choose to produce? Denote this quantity as QM. 3. One possible strategy is that each firm produces QM 2 . Would the resulting outcome be better for both firms (Pareto improvement)? Explain why this is not the equilibrium in the one period game. 4. Assume this game is infinitely repeated and the interest rate in this economy is r. For what values of r the strategy in (3) is sustainable by using a “Grim Trigger” strategy?
The payoff matrix presents the profits for Firms X and Y under their two individual pricing strategies. Suppose both firms have agreed to maximize their combined profits by colluding on their pricing strategies. Use the information in this payoff matrix to answer the two questions. Firm Y strategy Low price 18 High price $ 16 Firm X strategy Low price Firm X Profit = 71 Firm Y Profit 71 Firm X Profit = 105 Firm Y Profit = 49 = Compare the profits of Firm X when both firms respect the collusive agreement to the profits of Firm X when Firm X secretly cheats on the agreement. How much additional profit would Firm X earn by secretly cheating on the agreement to collude? Round your answer to the nearest whole number. High price Firm X Profit = 49 Firm Y Profit = 105 Firm X Profit = 87 Firm Y Profit = 87 Compare the profits of Firm Y when both firms respect the collusive agreement to the profits of Firm Y when both firms cheat on the agreement. By how much would the profits of Firm Y fall if…
Suppose two firms, A and B, have a cost function of ?(??) = 30??, for ? = ?, ?. The inverse demand for the market is given by ? = 120 − ?, where Q represents the total quantity in the market, ? = ?? + ??. 1. Solve for the firms’ outputs in a Nash Equilibrium of the Cournot Model. 2. Let Firm A be the first mover, and Firm B be the second mover. Solve for the firms’ outputs in a SPNE of the Stackelberg Model.
1. Consider the following Cournot model. The inverse demand function is given by p = 30 –Q, where Q = qi + q2. Firm 1's marginal cost is $6 (c1 = 6). Firm 2 uses a new technology so that its marginal cost is $3 (c2 = 3). There is no fixed cost. The two firms choose their quantities simultaneously and compete only once. (So it’s a one-shot simultaneous game.) Answer the following questions. а. Derive Firm 1 and Firm 2's reaction functions, respectively. b. Solve the Nash equilibrium (qı", q2"). What is the equilibrium price and what is the profit level с. for each firm?
Two firms produce Bliffs. They compete by simultaneously choosing prices in a single period. The demand for Bliffs is given by P(Q) = 100-2Q where Q is market quantity and P is market price. Firm 1 has costs C1(q1) = 20q1 and Firm 2 has costs C2(q2) = 10q2. Which statement is true? In the Nash equilibrium to the game, both firms play dominated strategies None of the other answers are correct O In the Nash equilibrium to the game, both firms play dominant strategies In the Nash equilibrium to the game, both firms slowly lower prices towards marginal costs O In the Nash equilibrium to the game, both firms set price equal to marginal cost
Suppose that there are only two firms in a market in which demand is given by p = 64 - Q, where Q is the total production of the two firms. Each firm can choose either a low level of output, qL = 15, or a high level of output, qH = 20. The unit cost of production for both firms is $4. Write down the normal-form representation of the game in which the strategic variable for each firm is the quantity of output and the firms make their choices simultaneously. Find the pure strategy Nash equilibrium of this game (quantities produced and market price).
Consider the following static game with two firms as the players. Each firm must decide either to upgrade (U) an existing good to a new version; or not upgrade it (N). The decisions are simultaneous. If a firm chooses to upgrade, they have to pay a fixed cost of 7. If they don’t upgrade, there is no fixed cost. The marginal cost is always equal to 3. The demand side of the market is as follows: If neither firm upgrades, each firm sells 2 units at price 4. If both firms upgrade, each firm sells 3 units at price 5. If only one firm upgrades, the one who upgrades sells 5 units at price 5, and the other firm does not sell anything.
Suppose that firms in a two-firm industry choose quantities every month, and each month the firms sell at the market-clearing price determined by the quantities they choose. Each firm has a constant marginal cost, and the market demand curve is linear of the form P = a - bQ, where Q is total industry quantity and P is the market price. Suppose that initially each firm has the same constant marginal cost. Further suppose that each month the firms attain the Cournot equilibrium in quantities. a) Suppose that it is observed that from one month to the next Firm 1’s quantity goes down, Firm 2’s quantity goes up, and the market price goes up. A change in the demand and/or cost conditions consistent with what we observe is: i) The market demand curve shifted leftward in a parallel fashion. ii) The market demand curve shifted rightward in a parallel fashion. iii) Firm 1’s marginal cost went up, while Firm 2’s marginal cost stayed the same. iv) Firm 2’s…

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?
