Since 1982, the U.S. Department of Justice, the Federal Trade Commission, and state attorneys general have used the Herfindahl-Hirschman Index (HHI) to measure market concentration for purposes of antitrust enforcement. The HHI of a market is calculated by summing the squares of the percentage market shares held by the respective firms. The Herfindahl Index formula is calculated by squaring the market share for each firm (up to 50 firms) and then summing the squares. Here's an example: Let's say there are four grocery stores in your town: Albert's, Bob's, Carl's and Donald's. Market share is broken down as follows: Albert's: 50% Bob's: 25% Carl's: 15% Donald's: 10% A company's market share is its percentage of total sales within a market or industry. To calculate the HHI for a proposed merger using the Herfindahl-Hirschman index formula, add the squares of each company's market share. For example, in 2018, Anheuser-Busch InBev held about 41% of the U.S. beer market, and MillerCoors had about 24%. To calculate the market concentration in Tiki's large metropolitan city, she will need to use the Herfindahl Index or HI, also known as the Herfindahl-Hirchman Index or HHI.The HI is a formula The Herfindahl index (also known as Herfindahl–Hirschman Index, HHI, or sometimes HHI-score) is a measure of the size of firms in relation to the industry and an indicator of the amount of competition among them. Named after economists Orris C. Herfindahl and Albert O. Hirschman, it is an economic concept widely applied in competition law, antitrust and also technology management. The Herfindahl–Hirschman Index (HHI), is an approach that is commonly used to measure market concentration. It is calculated by squaring the market share of each organization that is competing within a given market and then adding the resulting numbers together. The Herfindahl index is a variation of the market concentration marketing metric. Instead of a simple sum of the market shares of the larger brands in the marketplace, the Herfindahl index applies a multiple (squared) effect to the difference in the market shares for all/most brands.
