Hhi index levels

15 Mar 2014 First, I compute a Herfindahl index (HHI) based on firm level data reported in Compus- tat. To construct the Compustat HHI, the only data  perfect collusion but not intermediate levels of competition. Concentration measures, such as the Hirschman-Herfindahl Index (HHI), are commonly used in   Relevance and the level of theme investigation. Banks are one To sum up, sectoral concentration may be measured by the HHI index, the Gini coefficient and  to calculate the market concentration is the Herfindahl-Hirschman Index (HHI). the market based on geography, demographics as well as income levels etc. 30 Jul 2018 When looking at market concentration levels across the United using the Herfindahl-Hirschman Index (HHI), which has a range from 0 to 

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

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 Market share and HHI indices in the Guidelines Market shares and the overall level of concentration in a market normally give useful first information about the competitive situation in a market. The Guidelines therefore indicate, in Section III of the Guidelines, specific market share and concentration levels to specify in which situations the Commission is likely or not likely to have competition concerns. 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 index is a measure of the size of firms in relation to the industry and an indicator This threshold is considered to be 0.25 in the U.S., while the EU prefers to focus on the level of change, for instance that concern is raised if

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 Market share and HHI indices in the Guidelines Market shares and the overall level of concentration in a market normally give useful first information about the competitive situation in a market.
