- The top six firms in an industry have a total sales of the following respectively $54million, $47million, $45million, $40million, $30million, $25million; total industry sales are $261million. for this industry, what is the firm 4-firm concentration ratio? based on the value calculated, what market structures does this industry represent? Why? if the third and the six largest firms are anted to merge, what do you think the department of justice Would do? Why?Suppose that the six firms in industry A have annual sales of 40, 35, 12, 5, 5, and 3 percent of total industry sales. For the six firms in industry B, the figures are 35, 18, 15, 14, 10, and 8 percent. b. Calculate the four-firm concentration ratio and the Herfindahl index for each industry and compare their likely competitiveness. Instructions: Enter your answers as whole numbers. Industry A four-firm concentration ratio = Industry A Herfindahl index = Industry B four-firm concentration ratio = Industry B Herfindahl index = c. Industry A will be ________ (more/less) competitive than industry B. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.Suppose we have two markets, A and B, each consisting of seven firms. The market shares of the 5 largest firms (ordered by market share) are shown in the table below. True or false? (i) The CR3 and CR4 concentration ratios both point to the same market (either A or B) having more market power. (ii) The 6th largest firm in market B captures at most 8 percent of the market. (iii) The HHI of market B is at most 1,798 (in units of squared percent). (Hint: for positive x and y, (x+y)2=x2+y2+2xy≥x2+y2.) (iv) The HHI of market A is definitely larger than the HHI of market B.

Firm Market Share (%) 1 21.2 2 18.2 3 14.0 4 12.0 5 8 6 7.5 7 6.4 8 5 9 4 10 1 What is the four‑firm concentration ratio for the steel industry represented in the table? Round your answer to the nearest tenth.Suppose you are given the following firms and their annual sales data from last year in the cellular phone industry: Firm Sales (millions of dollars) Orange Is Better Than Apple S2, 000 Macro Hard S 1,300 Professors Can't See You Use Our Phones In Class $500 Phones "r" Us $800 Handhelds $1,000 Rings Up $300 We Sell You Cells $1,500 All other cellular phone companies combined sales $10, 700 Calculate the four-firm concentration ratio for this industry (show your work). Assuming that 40 percent is the dividing line between concentrated and competitive for this industry, how would you describe it?Total industry sales are $105 million. The top four firms account for sales of $15%, 12%, 10%, 8%respectively. What is the three-firm concentration ratio?
- . (Requires calculus). In the model of a dominant firm, assume that the fringe supply curve is given by Q = -1 + 0.2P, where P is market price and Q is output. Demand is given by Q = 11 – P.What will price and output be if there is no dominant firm? Now assume that there is a dominant firm, whose marginal cost is constant at $6. Derive the residual demand curve that it faces and calculate its profit-maximizing output and price. highest bidder, but both the winning and losing bidders must pay her their bids. So if Jones bids $1 they pay a total of $3, but Jones gets the money, leaving him with a net gain of $98 and Smith with -$1. If both bid the same amount, the $100 is split evenly between them. Assume that each of them has only two $1 bills on hand, leaving three possible bids: $0, $1 or $2. Write out the payoff matrix for this game, and then find its Nash equilibrium.The concentration and HHI reported in the U.S. Bureau of Census are useful because Multiple Choice -they are based on figures for the entire national market. -they are calculated by excluding foreign imports, hence they bias upward the degree of concentration. -the definition of product classes used to define an industry affects the results. -they provide information about whether large or small firms dominate an industry.EMERGENCY PLEASE: suppose a market consists 3 firms ( firm A, firm B, firm C) and firm A's sales account for 40% of market sales, while firm B and C each control 30% of the market. in this market, the four-firm concentration ration is therefore __________ and the Herfindahl-Hirshman index is equal to _____________. if the firm B and firm C merge, the new value of the Herfindahl-Hirshman index would change to__________. sothe Departement of Justice_________ likely to block this merger. suggestions for the first: suggestions for the second: suggestions for the third:
- Suppose that the firm in a competitive market faces the following revenues and cost: Quantity Total Revenue Total Cost 0 $0 3 1 $7 5 2 14 8 3 21 12 4 28 17 5 35 23 6 42 30 7 49 38 In order to maximize profits, the firm will produce__ a. 6 units of output because marginal revenue equals marginal cost. b. 8 units of output because marginal revenue equals marginal cost. c. 4 units of output because marginal revenue exceeds marginal cost. d. 1 unit of output because marginal cost is maximized.Consider two industries, each comprising ten firms. In industry A, the largest firm has a market share of 49 percent. The next three firms have market shares of 7 percent each, and the remaining six firms have equal shares of 5 percent each. In industry B, the top four firms share the bulk of the market with 19 percent apiece. The next largest firm accounts for 14 percent, and the smallest five firms equally split the remaining 10 percent of the industry. a. Compute the four-firm concentration ratio and HI for each industry. Compare these measures across the two industries. Which industry do you think truly exhibits a more competitive structure? Which measure do you think gives a better indication of this? Explain. b. Now let the three second largest firms in industry A merge their operations while holding onto their combined 21 percent market share. Recalculate the HI for industry A. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care…You are the manager of a firm that produces products X and Y at zero cost. You know that different types of consumers value your two products differently, but you are unable to identify these consumers individually at the time of the sale. In particular, you know there are three types of consumers (1,000 of each type) with the following valuations for the two products: Consumer Type Product X Product Y 1 $90 $60 2 70 140 3 40 160 d. What are your firm’s profits if you charge $210 for a bundle containing one unit of X and one unit of Y, but also sell the products individually at a price of $90 for product X and $160 for product Y?
