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.

INTERCEPT, CONSUMPTION LINE

The intercept of the consumption line indicates autonomous consumption, consumption that does not depend on the level of income or production. This can be thought of as the baseline level of consumption that would be undertaken if income falls to zero. Autonomous consumption is affected by the consumption expenditures determinants, which cause a change in the intercept and a shift of the consumption line. The value of the intercept of the saving line is the negative of the value of the intercept of the saving line.
