Suppose that three firms make up the entire wig manufacturing industry. One has a 50% market share, and the other two have a 25% market share each. The Herfindahl index of this industry is _____. a. 3,750 b. 1,000 c. 10,000 d. 5,000 e. 2,500 Mane Attraction, one of the firms with a 25% market share in the wig manufacturing industry, leaves the market. This would cause the Herfindahl index for the industry to _____. a. remain the same b. fall c. rise The largest possible value of the Herfindahl index is 10,000 because: a. an index of 10,000 corresponds to 100 firms with a 1% market share each b. an index of 10,000 corresponds to a monopoly firm with 100% market share c. an industry with an index higher than 10,000 is automatically regulated by the Justice Department
