In Industry 1, Firm A, B, C, D and E each has 20 percent of the market. In Industry 2, Firm A has 75 percent of the market, Firm B has 2 percent, Firm C has 2 percent, and Firm D and 20 other firms all have 1 percent each. Which of these two industries do you consider likely to be more competitive, and why?
*step by step please*
To measure the competitiveness, we need to calculate the HHI for every industry.
In industry 1, the HHI for every firm will be the same. So the total HHI = 5* 20*20 = 2000
In industry 2, the HHI for firm A = 75*75 = 5625
HHI for firm B and C each = 2*2 = 4
HHI for firm D = 20*20 = 400
HHI for firm E = 1*1 = 1
Total HHI for industry B = 5625+4+4+400+1 = 6034.
So industry 1 is more competitive as its HHI is lesser than industry 2’s HHI.
Industry A has four firms. The largest firm in Industry A has more than 90 percent of the market share. Industry B also has four firms, but each of those four firms in Industry B has 25 percent of the market share. The Herfindahl-Hirschman index will be A. larger for Industry B than Industry A, but the four-firm concentration will be the same. В. tte same for both industries, but the four-firm concentration will be larger for industry Y than Industry A C....
1. An industry having a four-firm concentration ratio of 85 percent: a. is an oligopoly. b. is monopolistically competitive. c. is a monopoly. d. approximates perfect competition. 2. Industry Y is dominated by four large firms that hold market shares of 15, 20, 30 and, 35. If all the firms in industry Y merged into a single firm, the Herfindahl Index would become: a. 100 b. 10,000 c. 100,000 d. 1,000
Suppose an industry originally consists of 11 firms (A, B, C, D, E, F, G, H, I, J & K) with the following market shares: Firm(s): A B C D E F G thru K Market Share: 20% 20% 15% 15% 10% 10% 2% each Now suppose Firms D & E merge. How will federal antitrust regulators (the Department of Justice and the Federal Trade Commission) respond? A. Merger will be allowed. B. Merger is unlikely to be challenged. C....
Consider two industries, industry W and industry X. In industry W there are five companies, each with a market share of 20% of total sales. In industry X, there are six companies. One company has a 50% market share and each of the other five firms has a market share of 10%. a. Calculate the four-firm concentration ratio for each industry. b. Calculate the Herfindahl-Hirschman Index (HHI) for each industry. c. What do the values of the two concentration measures imply about the...

1l. If a monopolistically competitive firm is incurring losses, then at the profit-max a price is above the average total cost curve. b. price is below the average total cost curve c. price is equal to marginal revenue. d. price is less than marginal revenue. e. average total cost equals marginal cost. Both competitive and monopolistically competitive firms a. can maximize profit by raising price. b. cannot control or set their own price c. can maximize profit by producing to...
Consider a perfectly competitive industry in which each firm i has a total cost function given by the equation: TC= 128 + 4q+2q^2. Further assume that the industry demand function is given by the following: P = 84 – 2Q. a) Describe the long run market equilibrium. That is, identify the equilibrium price and quantity, output for each firm, the number of firms in the industry and the level of producer and consumer surplus. What is the value of own...
