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. Herfindahl-Hirschman Index (HHI) = 2,778. Since the score is higher than 2,500, this would represent that our toy industry is highly concentrated in nature and healthy competition is not visible. You can refer the above given excel template for the detailed calculation of the Herfindahl index. Why Use the Herfindahl-Hirschman Index and Why Not? 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:

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 Herfindahl-Hirschman index (HHI), also called HH index, in economics and finance, a measure of the competitiveness of an industry in terms of the market concentration of its participants. Developed by the American economist Orris C. Herfindahl and the German economist Albert O. Hirschman, it is based on the following formula: HHI = s 1 2 + s 2 2 + ⋯ + s n 2 where n is the number of firms in To calculate this number at the supplier level, I had to add Supplier as a row and select Compute using-> Supplier (Sheet 1) However, this of course gives the same answer for each supplier. To get one single number (i.e. the Hirschman Herfindahl index), 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 primary advantages of the Herfindahl-Hirschman Index (HHI) are the simplicity of the calculation necessary to determine it and the small amount of data required for the calculation. In this simplified trade matrix the rest of world is a single share. This type of aggregation will push the calculated Hirschmann index up. A Hirschmann index can also be calculated using import or trade shares. Regional Hirschmann index is sometimes called the Hirschmann-Herfindahl index (HHI).
