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. The Herfindahl index gives a better indication of the relative market control of the largest firms than can be found with the four-firm and eight-firm concentration ratios.

AUTONOMOUS CONSUMPTION

Household consumption expenditures that do not depend on income or production (especially disposable income, national income, or even gross domestic product). That is, changes in income do not generate changes in consumption. Autonomous consumption is best thought of as a baseline or minimum level of consumption that the household sector undertakes in the unlikely event that income falls to zero. It is measured by the intercept term of the consumption function or the consumption line. The alternative to autonomous consumption is induced consumption, which does depend on income.
