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.

SELF CORRECTION, AGGREGATE MARKET The automatic process in which the aggregate market adjusts from short-run equilibrium to long-run equilibrium. Self-correction results through shifts of the short-run aggregate supply curve caused by changes in wages (and other resource prices). The self-correction mechanism acts to close both recessionary gaps and inflationary gaps. The short-run aggregate supply curve increases (shifts rightward) due to lower wages to close a recessionary gap and decreases (shifts leftward) due to higher wages to close an inflationary gap.
