HHI below 100 indicates a highly competitive industry, HHI between 100 and 1,500 indicates an unconcentrated industry, HHI between 1,500 to 2,500 indicates moderate market concentration, HHI above 2,500 indicates high market concentration.
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 resulting numbers. It can range from close to zero to 10,000.
Moreover, What does a low HHI mean?
Herfindahl-Hirschman Index
Secondly, How do you interpret HHI?
A market with an HHI of less than 1,500 is considered to be a competitive marketplace, an HHI of 1,500 to 2,500 to be a moderately concentrated marketplace, and an HHI of 2,500 or greater to be a highly concentrated marketplace.
Simply so, How is Herfindahl calculated?
The Herfindahl Index formula is calculated by squaring the market share for each firm (up to 50 firms) and then summing the squares. In a perfectly competitive market, HHI approaches zero. Let’s say there are thousands of restaurants in your city, but the top 50 each have 0.1% of the market share.
Why is HHI a better measure of competitiveness over CR?
Abstract. Market concentration can be measured in different ways, i.e. by using different indicators. In the broadest use are the concentration ratio (CR) and Herfindahl-Hirschman Index (HHI). It is believed that the Herfindahl-Hirschman Index is more precise measure because it takes into account all companies.

How do you calculate the 4 firm concentration ratio?
