HERFINDAHL-HIRSHMAN INDEX: 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.

IMPORTS LINE

A graphical depiction of the relation between imports bought from the foreign sector and the domestic economy's aggregate level of income or production. This relation is most important for deriving the net exports line, which plays a minor, but growing role in the study of Keynesian economics. An imports line is characterized by vertical intercept, which indicates autonomous imports, and slope, which is the marginal propensity to import and indicates induced imports. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the net exports line, derived as the difference between the exports line and imports line, onto the consumption line, after adding investment expenditures and government purchases.
