Question
Chapter 7, Problem 1CACQ
To determine
The four-firm concentration ratio is to be calculated.
Expert Solution & Answer
Answer to Problem 1CACQ
Four-firm concentration ratio is 38%
Explanation of Solution
Given:
The total sales of all the 10 firms selling the product are $2000000.
The first four firm's sales are $260000, $220000, $150000 and $130000
The four-firm concentrationratio measures the proportion of sale of industry being done by top four firms. It shows market power in an industry.
Since, the first four firm's sales are $260000, $220000, $150000 and $130000, the four-firm concentration ratio is given by:
Hence, the four-firm concentration ratio in the market for product is 0.38 or 38%.

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 $310,000, $235,000, $205,000, and $ 140,000, respectively. Calculate the four - firm concentration ratio in the market for product X. Instruction: Enter your response rounded to two decimal places,

- 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.

Each firm must choose either a high price or a low price simultaneously. Use the following information to create the profit matrix: If HP and Lenovo both set high prices, HP’s profit is $40 million and Sony’s profit is $35 million. If HP sets high price and Sony sets low price, HP’s profit is $25 million and Sony’s profit is $40 million. If HP sets low price and Sony sets high price, HP’s profit is $50 million and Sony’s profit is $10 million. If HP and Sony set low prices, HP has $20 million and Sony has $15 million. Please answer the follow questions: Does Sony have a dominant strategy? HP? If so, which one? If HP and Sony maximize their profits non-cooperatively, what is the Nash-equilibrium for this profit matrix? Instead, if HP and Sony maximize their joint profits cooperatively, what is the equilibrium?
