Hhi index levels
The following data are from the Economic Census. All of these reports classify industries by the percent of output accounted for by the largest 4, 8, 20 and 50 companies. Only the manufacturing reports include the Herfindahl-Hirschman Index. AHI numbers (Alpha Hypopnea Index) are a method doctors use to classify the severity of sleep apnea in a person.

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. Notes: Market concentration was measured using the Herfindahl-Hirschman Index (HHI), which has a range from 0 to 10,000. The HHI was used to create the following market concentration categories: unconcentrated (HHI<1,500), moderately concentrated (1,500 ≤ HHI < 2,500), highly concentrated (2,500 ≤ HHI < 5,000), and super concentrated (HHI ≥ 5,000). Hi, My Wiley study notes say the following: If the HHI of an industry is 1000-1800, it is moderately concentrated, and an increase of the HHI above 100 (as a result of a merger) is likely to be challenged. Otherwise, if the increase is below 100, it will likely not be challenged. My question is: what if the HHI is something close, like 1780? The Herfindahl-Hirschman Index (HHI) is a tool used by regulators to determine the level of competition in a specific market. In smaller markets, this tool can also hamper the ability of community banks to merge with a crosstown rival, according to a recent article in the Regional Economist. 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
The HHI value is very important to analyze how the market power can be enhanced. Since the different values signify different levels of market concentration, we will understand when and where the firm needs to improve or slow down or retain the current scenario.

The Herfindahl-Hirschman Index (HHI) is a commonly accepted measure of market concentration. It is calculated by squaring the market share of each firm competing in a market and then summing the The formula to calculate Herfindahl-Hirschman Index is as follows: Where: S1, S2, etc… – refers to the percentage market share that various companies hold in the given industry Herfindahl-Hirschman Index Scale. The Herfindahl-Hirschman Index ranges from 1 (least concentrated) to 10,000 (most concentrated).

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 HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. For example, for a market consisting of four firms with shares of 30, 30, 20, and 20 percent, the HHI is 2,600 (30 2 + 30 2 + 20 2 + 20 2 = 2,600). The HHI takes into account the relative size distribution of the firms in a market. HHI Index can range from 0 to 10,000 if whole percentage numbers are used. Similarly, it can range from 0 to 1, where market shares are used as fractions. E.g. if there’s only one firm operating in an industry, holding 100% market share, it’s respective HHI would be exactly 10,000 or 1 and would indicate a monopoly. 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 HHI value is very important to analyze how the market power can be enhanced. Since the different values signify different levels of market concentration, we will understand when and where the firm needs to improve or slow down or retain the current scenario. HHI weighted by the occupation’s share of total group employment. Thus, occupations with high employment levels have more influence than occupations with low employment levels on the aggregate HHI, allowing the aggregate index to reflect more closely the industry concentration patterns of the occupations that make up
