HERFINDAHL 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.

LONG-RUN AGGREGATE MARKET

A macroeconomic model relating the price level and real production under the assumption that ALL prices are flexible. This is one of two aggregate market submodels used to analyze business cycles, gross production, unemployment, inflation, stabilization policies, and related macroeconomic phenomena. The other is the short-run aggregate market. The long-run aggregate market isolates the interaction between aggregate demand and long-run aggregate supply. The key assumption of this model is that ALL prices, especially resource prices, are flexible. The primary result of this model is that the economy achieves long-run equilibrium at full-employment real production.
