The Herfindahl-Hirschman index and occupational concentration by industry. March 05, 2014. Some occupations are found in nearly every industry in the United States, while others are specific to one or only a few industries. The Herfindahl-Hirschman index (HHI) can be used to provide a measure of occupational concentration by industry. The Herfindahl-Hirschman Index Stephen A. Rhoades, of the Board's Division of Research and Statistics, prepared this technical note. The Herfindahl-Hirschman index, better known as the Herfindahl index, is a statistical measure of concentration. It has achieved an unusual degree of visibility for a statistical index because of its use by useful surrogate for individual data. However, in practice, there is uncertainty on the reliability and adequacy of aggregated data. In this paper we estimate the Herfindahl-Hirschman Index (HHI) for a loan portfolio using both aggregate data and individual data. Then, we compare both estimates to assess the reliability of the aggregated data.

Hirschman Herfindahl index is a measure of the dispersion of trade value across an exporter's partners. A country with trade (export or import) that is concentrated in a very few markets will have an index value close to 1. Similarly, a country with a perfectly diversified trade portfolio will have an index close to zero. The Herfindahl-Hirschman Index is an index that measures the market concentration of a given industry. A highly concentrated industry is one where only a few players in the industry hold a large percentage of the market share, leading to a near-monopolistic situation. The Herfindahl Index (H) ranges from 1/N to one, where N is the number of firms in the market. Equivalently, if percents are used as whole numbers, as in 75 instead of 0.75, the index can range up to 100 2 , or 10,000. The Herfindahl Index takes into account a number of factors that give analysts and experts a better, more comprehensive view of the health of a specific market. When that market is populated by a lot of big companies, all of them relatively the same size, the index will be at or near zero. 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-Hirschman Index, also called the Herfindahl Index, measures the extent to which market share is concentrated among a few or many companies. It measures market concentration of an industry’s fifty biggest firms in order to determine whether that industry has a healthy number of competitors or is nearing monopoly. Furthermore, the Justice Department uses the Herfindahl Index to decide whether a merger is good for competition in the marketplace. A market with an HHI under 1,000 is considered competitive. The Justice Department is likely to scrutinize a merger in an industry with a post-merger HHI of between 1,000 and 1,800, and it is almost certain to
