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-Hirschman Index (HHI) calculator computes the HHI market concentration index for a list of companies based on their market share. What the Herfindahl Index Measures 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. 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%. 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 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.
Hi all, this is my first post here. I am currently doing my master thesis. As part of this, I would like to calculate the Herfindahl-Hirschman Index for

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. Herfindahl-Hirschman Index or HHI score refers to a measure of market concentration and is an indicator of the amount of competition in a particular industry. HHI Index formula helps in analyzing and observing, if a particular industry is highly concentrated or close to monopoly or if there is some level of competition around it. Herfindahl-Hirschman Index The term “HHI” means the Herfindahl–Hirschman Index, a commonly accepted measure of market concentration. The HHI is calculated by squaring the market share of each firm competing in the market and then summing the resulting numbers. The Herfindahl-Hirschman Index (HHI) is a widely used measure of market concentration. The HHI is calculated by squaring the market share of each firm in the industry and summing the result: HHI = s1^2 + s2^2 + s3^2 + + sn^2 where s is the market share of each firm.
Could you please explain the intution behind this calculation? in other words, why in 2sls regressions, we need to have herfindahl index
