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.

THREE-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes the three domestic sectors, the household sector, the business sector, and the government sector. This Keynesian model variation adds the government sector (or public sector) to the household and business sectors that make up the two-sector model. This model enables an analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the C + I + G line and the 45-degree line. Two related models are the two-sector Keynesian model and the four-sector Keynesian model.
