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.

MARGINAL PROPENSITY TO IMPORT The change in imports purchased from the foreign induced by a change in income or production (national income or gross domestic product). The marginal propensity to import (abbreviated MPM) is another term for the slope of the imports line and is calculated as the change in imports divided by the change in income or production. The MPM plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to the multiplier process. A related marginal measure is the marginal propensity to consume.
