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.

INFLATION CAUSES

Inflation, the persistent increase in the average price level, can be caused by an increase in aggregate demand or a decrease in aggregate supply. This suggests two basics sources, causes, or types of inflation--demand-pull inflation and cost-push inflation. While short-term bouts of inflation (up to several months) can result from anything (determinant) that might cause either increases in aggregate demand or decreases in aggregate supply, long-term inflation (a year or more) is possible ONLY through persistent increases in the money supply. As such, while demand-pull inflation and cost-push inflation are convenient ways to catalog the transmission mechanisms of inflation, the ultimate CAUSE of inflation is money.
