Attempts: Keep the Highest: /3 3. The Herfindahl-Hirschman inde Suppose that three firms make up the entire bicycle manufacturing industry. One has a 60% market share, and the other two have a 20% market share each. The Herfindahl-Hirschman index of this industry is A new firm, Abe\'s Bikes, enters the bicycle manufacturing industry and immediately captures a 20% share of the market. This would cause the Herfidahl-Hirschman index for the industry to Why is the largest possible value of the Herfindahl-Hirschman index is 10,000 An industry with an index higher than 10,000 is automatically regulated by the Justice Department. An index of 10,000 corresponds to a monopoly firm with 100% market share. An index of 10,000 corresponds to 100 firms with a 1% market share each.

Solution
3)
= (60)2 +(20)2 +(20)2 = 3600+400+400 = 4400

Under profit maximization Profit maximizing condition is MR = MC.
Under Marginal Cost Pricing firm will charge price = MC.
Under average cost pricing firm will charge price = AC.
