PROBLEM (5) In a dominant firm market with demand Q = 30 − p, the dominant firm has MC(Q) = 2Q (that is, with TC(Q) = Q^2) and the fringe is composed of 5 identical firms, each with MC(Q) = 10Q (that is, with TC(Q) = 5Q^2). (a) Calculate the market price in the dominant firm model. Calculate the quantity produced by the fringe. (b) Now assume that the 5 fringe firms form a “union”, and act as 5 “plants” of the union firm and this union firm competes as one single firm against the dominant firm in quantities, as in Cournot competition. What is the Cournot-Nash equilibrium price and quantity in this market organization? (c) Now, the dominant firm convinces the “union” not to compete with it but instead collude (to maximize the sum of profits) to form a cartel. What is the market price and quantity? (d) Back to the problem description. If all the firms (the dominant firm and the 5 fringe firms) acted as price takers, as in the perfect competition, what would be the market equilibrium…
The figure shows the market demand curve for penicillin, an antibiotic medicine. Initially, the market was supplied by perfectly competitive firms. Later, the government granted the exclusive right to produce and sell penicillin to one firm. The figure also shows the marginal revenue curve (MR) of the firm once it begins to operate as a monopoly. The marginal cost is constant at $3. irrespective of the market structure.

1. if the total cost function for this market is TC = 500 + 10Q2 , calculate the total and marginal costs for each of the quantities in the table. what is the demand function for this market? 2. What are the profit-maximizing quantity, price, and profit for this market? 3. If there are two firms Atlas and Bowden in this market with the same earlier total cost function and they engage in Cournot competition, what is each firm's equilibrium quantity, price, and profit? [NB: round quantities to nearest integer to find equilibrium quantity, price, and profit]
Economics: Industrial Economics Question: In a market operating under quantity competition there are 2 firms (Cournot duopoly). The cost structure of firm 1 is given by C1(q1) = 675 + 60q1 + (q1)^2 and that of firm 2 is given by C2(q2) = 375 + 20 q2 + 5 (q2)^2. The inverse demand function is P = 300 - 2 Q1, where Q = q1 + q2. Define the profit maximization problem that every firm faces and solve for the respective best response functions. Use these (or the first order condition directly) to answer the following: 1. The Nash Equilibrium quantity produced by firm 1 q1* is Choices: A. 33.3 B. 38.3 C. 40 D. 35 2. The Nash Equilibrium quantity produced by firm 2 q2* is Choices: A. 15 B. 53.3 C. 20 D. 21.7 3. The Nash Equilibrium price is Choices: A. 126.7 B. 180 C. 200 D. 190 4. The Lerner Index for the market is closest to Choices: A. 0.29 B. 0.66 C. 0.43 D. 0.57 Thank you for your help and support Instructor Agent!
Suppose Firm X is a dominant firm in a market where the market demand is Q = 1200 -2p. Once Firm X sets its price, those small competitors set their prices a little lower so that they can always sell up to their capacity. Assume the small firms’ combined capacity is 100 units. Further assume Firm X’s marginal cost is 50. Answer the following questions. Let Q^D be the quantity produced by the dominant firm. Write down the residual demand function faced by Firm X. (Hint: Think about how Q and Q^D are related.) Find Firm X’s profit-maximizing price.
A) Suppose there are just two firms, 1 and 2, in the oil market and the inverse demand for oil is given by P = 90 – 3Q. The marginal cost for each firm is €18. Calculate the level of output that each firm would produce at the Cournot equilibrium. B) Suppose there are just two firms, 1 and 2, in the oil market and the inverse demand for oil is given by P = 60 – Q. The marginal cost for each firm is €36. What price should Firm 1 charge at the Cournot equilibrium? C) Consider the production function Q = 10KL. Will the MRTS for this production function remain constant along the Q = 200 isoquant? Explain briefly.
Suppose that there are two firms in an industry and they face market demand y=400-0.5p where y=y1+y2 . The total cost functions of the firms are C1(y1)= 40y1 and C2(y2)= 2y22. a) Assume initially that the firms enter into Cournot competition. Calculate the equilibrium market price and each firm’s equilibrium output. That is, find y1c, y2sand pc.b) Calculate the equilibrium market price and each firm’s equilibrium output assuming that firm 2 is the Stackelberg leader and firm 1 is the follower. That is, find y1s, y2sand ps.
**Practice** Consider a market with three firms. Each firm has a different cost function. We assume C1(q1) = 7q1, C2(q2) = q2 + 1, and C3(q3) = 3q3.
Consider the weekly market for gyros in a popular neighborhood close to campus. Suppose this market is operating in long-run competitive equilibrium with many gyro vendors in the neighborhood, each offering basically the same gyros. Due to the structure of the market, the vendors act as price takers and each individual vendor has no market power.
The following graph shows the marginal cost (MC) and average total cost (ATC) and the initial demand (D₁) curves of a perfectly competitive firm. Suppose this firm forms a cartel with other firms in the industry. Because of the cartel agreement, it has been assigned a production quota of 35 units. The cartel price is $80 per unit of output. You may use the purple rectangle (diamond symbols) to help you answer the questions that follow. You will not be graded on any changes you make to the graph.

C2) Consider an industry with only two firms: firm A and firm B. The industry's inverse demand is P(Q) = 400 - ¹1/Q, 10 where P is the market price and Q is the total industry output. Each firm has a marginal cost of $10. There are no fixed costs and no barriers to exit the market. a) Suppose that the two firms engage in Cournot competition. Find the equilibrium price PNE in the industry, the equilibrium outputs QANE and QBNE, as well as the profits NEA and NEB for each firm. marks] b) Suppose the two firms engage in Stackelberg competition, with firm A moving first, and firm B moving second. Find the equilibrium price PS in the industry, the equilibrium outputs QS and QBS, as well as the profits π and TSB for each firm. в c) For this subquestion only, suppose that firm B has a fixed cost of $200 000: What will firm B's optimal decision be, and what will be the resulting market structure? Now assume that instead of having two firms in the market, we have a monopoly facing the inverse…
Here is a market with three firms: 1, 2, and 3. The demand curve is P=100-Q. There is no fixed cost but the marginal cost 10 for all firms. Firm 1 is a leader firm so that it decides the quantity Q1 first. Then two firms respectively decide their quantities Q2 and Q3 simultaneously. 1) At an equilibrium (SPE), Q1 is Q2=Q3= 2) At the equilibrium, (the market quantity) Q= and (the market price) P= 3) The profit of firm 1 is while the profit of firm 2 and 3 respectively is
