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.

SHORT-RUN AGGREGATE SUPPLY The total (or aggregate) real production of final goods and services available in the domestic economy at a range of price levels, during a period of time in which some prices, especially wages, are rigid, inflexible, or otherwise in the process of adjusting. Short-run aggregate supply, commonly abbreviated SRAS, is one of two aggregate supply alternatives, distinguished by the degree of price flexibility. The other is long-run aggregate supply. Short-run aggregate supply is combined with aggregate demand in the short-run aggregate market analysis used to analyze business-cycle instability, unemployment, inflation, government stabilization policies, and related macroeconomic topics.
