- 54. Duopoly quantity-setting firms face the market demand p = 150 – q1 – 42. Each firm has a marginal cost of $60 per unit a) What is the NE? b) What is the Stackelberg equilibrium when Firm 1 moves first?1. Two firms produce identical products at zero cost, and they compete by setting prices. If each firm charges a low price, the both firms earn profits of zero. If each firm charges a high price, then each firm earns profits of $30. if one firm charges a high price and the other firm charges a low price, the firm that charges the lowest price earns profits of $50 and the firm charging the highest price earns profits of zero. a. Write this game in normal form. b. Suppose the game is infinitely repeated. Can the players sustain the "collusive outcome" as a Nash equilibrium if the interest rate if 50 percent?
- 12. Consider a duopoly market. Two firms are selling identical products and all costs are assumed to be zero for simplicity. Market demand schedule is given in the following table. Note that firms always choose an integer value for the quantity of production. Quantity Price Total Profit 3 $12 4 11 5 8 6 6. 7 4 8 2 1 10 a. Fill in the column of total profit.5. Suppose there are two firms in a Cournot type setting (choosing quantity simultaneously). How would an increase in the marginal cost of firm 1 change the equilibrium output of firm 1 and firm 2? Depict your answer graphically.8. Suppose there are two identical firms in an industry who compete by setting quantities. The output of firm 1 is denoted by q1 and that of firm 2 is denoted by q2. Each firm faces a constant marginal cost of 3. Let Q denote total output, 1.e. Qq1 +42. The inverse demand curve in the market is given by P-15-Q (d) Suppose firms interact repeatedly over an infinite horizon, and firms have a common discount factor & € (0,1). Specify a trigger strategy for each firm to sustain the collusive arrangement as an equilibrium outcome. Cal- culate the minimum value of & for which such a trigger strategy collusion as an equilibrium in the repeated interaction. ain
- 1. Suppose we live in a world where the widgets market is a monopolistically competitive market with homogenous firms (i.e. no productivity differences among firms). There are two countries: A and B. In each country, consumer demand for widgets can be written as Q = S x- x (P – P), 30 where n is the number of widget firms, P the price of widget charged by the firm, and P the average price of widget by other firms in the market. Moreover, widget firms in both countries have the same total cost function, which is C = 750 + (5 × Q). It is also given that marginal revenue of each 30Q firm can be written as MR = P – Total demand for widget in country A is SA = 900 and Sg = 1600 in country В. a) Derive the average cost function from the total cost function. What is the marginal cost? b) Calculate the number of firms and the prices of widget in each country when trade is not allowed (that is, calculate na, ng, Pa, PBÌ- c) Calculate the number of firms and the price of widget in the unified…Economics 1) How many buyers are there in a perfectly competitive market?A) FewB) TwoC) ManyD) One2) A market in which there are many buyers and sellers, every firm sells the same standardized product, buyers and sellers have full information about the product and its price, and it is easy for firms to enter and exit the market is known as _____ market.A) monopolyB) oligopolyC) duopolyD) a perfectly competitive3) Which of the following is NOT a reason that firms in a perfectly competitive market are price takers?A) There are many firms that a buyer can choose from.B) Each firm can sell more of its goods at a lower price than at the market price.C) Each buyer has perfect information about all alternatives.D) Each firm's good is a perfect substitute for another firm's good.Attempts 6. Oligopolies This chapter discusses companies that are oligopolists in the market for the goods they sell. Many of the same ideas apply to companies that are oligopolists in the market for the inputs they buy. If sellers who are oligopolists try to increase the price of goods they sell, the goal of buyers who are oligopolists is to try to decrease the prices of goods they buy. Major league baseball team owners have an oligopoly in the market for baseball players. The owners' goal is to keep players' salaries. Keep the Highest/3 True or False: This goal difficult to achieve because baseball players demand more money. O True O False Baseball players went on strike in 1994 because they would not accept the salary cap that the owners wanted to impose. True or False: The owners felt the need for a salary cap to help prevent any team from cheating. O True O False
- 3. Demand for a good produced by a duopoly is given by P = 100 - Q. Both firms have constant marginal costs, MC = 20 and zero fixed costs. Firms can choose to maximize profit or revenue. Suppose firm 1 choose to maximise profit and firm 2 choose to maximise revenue. Determine the equilibrium price and quantity of each firm.Answer 4 and 4Question 4 Many companies reward their managers based on profits so that the managers will make decisions to maximize profits. However, some companies are paying their managers based on sales or revenue, instead of profits, so their managers will make decisions to maximize revenue. For example, at Reebok, the former CEO Paul Fireman received a nickel for every pair of shoes sold. a. Suppose that there are two existing firms in the market competing in quantity. Ignore market uncertainty and long-run competition. Firm B's manager is always paid based on firm B's profits. Firm A has been paying its manager based on profits but now changes to pay the manager solely based on revenue. Each manager chooses the production level (quantity) for his firm simultaneously. Is it possible for the above change in firm A's compensation system to increase firm A's profits? What are the direct effects and strategic effects on firm A's profit? Explain. Direct Effect (Circle one): Positive Negative…
