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.

IMPACT LAG

The time lag that occurs between the implementation of a government policy designed to correct an economic problem and the complete impact of the policy. The impact lag is based on the multiplier process and can last up to a year or two or even longer. This "outside lag" is one of four policy lags associated with monetary and fiscal policy. The other three "inside lags" are recognition lag, decision lag, and implementation lag. All four policy lags can reduce the effectiveness of business-cycle stabilization policies and can even destabilize the economy.
