Market share Market share Firm Industry 1 60 Industry 2 123456789 5 5 5 2222 5 4 5 5 5 5 4444 1 a. Compute the 4-firm concentration ratios for these two industries. b. Compute the Herfindahl-Hirschman Index (HHI) for the two industries. c. Two of the big firms in Industry 2, each with a 20% market share, wish to merge into a single larger firm with a 40% market share. Compute the HHI for the 8 firms that would exist if the merger occurred. Shares would now be 40% for the merged firm, 20% for two firms, and 4% for the five small firms.
