HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is a measure of concentration of the production in an industry that's calculated as the sum of the squares of market shares for each firm. This is an alternative method of summarizing the degree to which an industry is oligopolistic and the relative concentration of market power held by the largest firms in the industry.

Prices tend to be the most inflexible in resource markets, especially labor markets, and the least inflexible in financial markets, with product markets falling between the two.
