Ten firms compete in a market to sell product X. The total sales of all firms selling the product are $1,500,000. Ranking the firms' sales from highest to lowest, we find the top four firms' sales to be $375,000, $305,000, $245,000, and $ 195, 000, respectively. Calculate the four - firm concentration ratio in the market for product X.

Economics: Industrial Economics Question: In a market that operates under quantity competition there are 2 firms (Cournot duopoly). The inverse demand function is P = A - B Q. The cost structure of firm 1 is given by C1(q1) = F1 + c1 q1 and that of firm 2 is given by C2(q2) = F2 + c2 q2. Prior to competing, the two firms can engage in research at levels (x1, x2) respectively in order to lower their marginal costs. As a result, marginal costs are c1 = c - x1 - β2x2 and c2= C - x2 - β1 X1. where β1 = β2 > ½. Finally, the research costs are F1 = a1 (x1)^2 /2 and F2 = a2 (x2)^2 /2, where a1 > 0 and a2> 0. 1. The Nash Equilibrium research levels are Choices: A. Higher than the cooperative research levels for both firms. B. Higher than cooperative research levels for firm 1 but lower for... C. Lower than the cooperative research levels for both firms. D. Higher than cooperative research levels for firm 2 but lower for... 2. An increase in the value of a2 would Choices: A.…
Captain Catahoula and Bow Wow Wonder are two of the four firms in the dog food industry. Before they notify the Federal Trade Commission and the Department of Justice of their plans to merge, Captain Catahoula hires you to determine the concentration of this industry. Use the table to calculate the Herfindahl-Hirschman Index (HHI) for this dog food industry and then complete the sentence. Firm Bow Wow Wonder Waggin' Tails Mongrel Munchies Captain Catahoula HHI: Industry 10% 24% 26% 40% What is the HHI for this dog food industry?

Two firms, A and B, sell the same good X in a market with total demand Q = 100 – P. The two firms compete on quantities and decides how much to produce simultaneously. Firm A cost function is C(qA) = 40qA. Firm B cost function is C(qB) = 60qB. 1. Find the best reply functions of both firms and represent them in a graph. 2. Find the quantity produced by each firm in a Nash equilibrium. 3. Find the firms and consumers surplus. 4. Compare the surplus of firms found above with the surplus arising when both firm cooperate to sustain a monopoly outcome. 5. Assume now that A and B compete as in a Stackelberg model. A chooses first and B chooses after observing the choice of A. Find equilibrium quantities produced by each firm and the market equilibrium price.
Two firms are engaged in Cournot (simultaneous quantity) competition. Market-level inverse demand is given by P = 160 − 4Q Firm 1 has constant marginal costs of MC1 = 8, while Firm 2 has constant marginal costs of MC2 = 24. 1) Does there exist a low enough positive marginal cost for firm 1 such that firm 1 acts like a monopoly in this market, if so what is the MC if not why?

Suppose that a small town has seven burger shops whose respective shares of the local hamburger market are (as percentages of all hamburgers sold): 18 percent, 24 percent, 20 percent, 11 percent, 10 percent, 9 percent, and 8 percent. The four-firm concentration ratio for the hamburger industry in this town is percent. (Enter your response as a whole number.) The Herfindahl index for the hamburger industry in this town is (Enter your response as a whole number.) Suppose the top three sellers combined to form a single firm. The four-firm concentration ratio would be percent. (Enter your response as a whole number.) Suppose the top three sellers combined to form a single firm.

QUESTION 13 Consider a market where two firms (1 and 2) produce differentiated goods and compete in prices. The demand for firm 1 is given by D₁(P₁, P2) = 140 - 2p1 + P2 and demand for firm 2's product is D2 (P1, P2) 140 - 2p2 + P1 Both firms have a constant marginal cost of 20. What is the Nash equilibrium price of firm 1? (Only give a full number; if necessary, round to the lower integer; no dollar sign.)
The firm ACME, Inc. operates in a competitive market because OACME, Inc. is one of a few firms and entry in this market is easy OACME, Inc. can influence the market price and sells a product different from other firms in the market OACME, Inc. is one of many firms selling the same product and, market entry is easy OACME, Inc. is one of many firms selling the same product and, market entry is blocked
In the Cournot equilibrium, how much profit does firm 1 and firm 2 make in profit? (Round off to at least 2 decimal places, use negative numbers for losses.)
The following table reports the four firm concentration ratio for five different industries: Part 1: Refer to the table above. In which industry do the four largest firms have the most market power? Part2: Refer to the table above. I'm which industry do the four largest firms have the least market power?
Problem 3. Firm 1, Firm 2 and Firm 3 are the only competitors in a market for a good. The price in the market is given by the inverse demand equation P=10 (Q1+Q2+Q3) where Q, is the output of Firm i (i=1,2,3). Firm 1's total cost function is C₁ = 4Q₁+1, Firm 2's total cost function is C₂ = 2Q2 +3, and Firm 3's total cost function is C3 = 3Q3 + 2. Each firm wants to maximize its profits and they simultaneously choose their quantities. Determine a Nash equilibrium in this market.
