Measure of Concentration: HHI • The Department of Justice and Federal Trade Commission Merger Guidelines use the Herfindahl-Hirschman Index • HHI = = the sum of the squared market shares • 1 firm, with 100% market share (a monopoly): HHI = 1002 = 10,000 • 2 firms, each with a 50% market share: HHI = 502 + 502 = 5,000 • 4 firms, with market shares of 30%, 30%, 20%, and 20%: HHI = 302 + 302 + 202 + 202 = 2,600 • 10 firms, each with market shares of 10%: HHI = 10 (102) = 1,000
Concentration Today In 2012, EMI was eliminated as it’s recording operation was acquired by Universal and it’s music publishing business was acquired by Sony. Universal agreed to sell-off nearly two-thirds of EMI’s labels to gain regulatory approval.
