Consider an industry consists of three firms (Firm-A, Firm-B and Firm-C) with sales of AED300,000, AED700,000, and AED250,000; respectively.
Calculate the Herfindahl-Hirschman index (HHI) for the industry.
Calculate the four-firm concentration ratio (C4).
Do you think the ‘Department of Justice’ (see the guideline below) would attempt to block a horizontal merger between Firm-A and Firm-C)?
The Department of Justice’s Guidelines (Suppose):
Suppose that the Department of Justice’s Guidelines suggest that antitrust authorities are more likely to challenge a merger when the relevant Herfindahl-Hirschman index is greater than 2,500 and the resulting increase in the index as a result of the merger is more than 200.
Suppose that a small town has six burger shops whose respective shares of the local market are (as percentages of all hamburgers sold): 26%, 20%, 18%, 14%, 12%, 10%,
What is the four-firm concentration ratio of the hamburger industry and what is the Hirchmann Herfindahl Index (HHI) for the hamburger industry in this town?
Is it true that a merger between two firms that are not already in the top four by size can affect both the four-firm concentration ratio and the Her findahl-Hirshman Index? Explain briefly.

- The table shows a hypothetical demand schedule for monosodium glutamate (MSG). Ajinomoto holds 5050% of the market, Jiali holds 3030% of the market, and Quingdao holds 2020% of the market. Suppose the three firms agree to form a cartel to fix production of monosodium glutamate. Assume marginal cost equals zero, and the output is split equally across the firms. What quantity maximizes the cartel's profit?
