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.

An exchange rate determined through the unrestricted interaction of supply and demand in the foreign exchange market. Also termed floating exchange rate, this is one of three basic exchange rate policies used by domestic governments to control their exchange rates with the goal of affecting international trade, balance of trade, and balance of payments. This policy is based on the view that the free interplay of market forces is most likely to generate a desireable pattern of international trade. The other two policies are fixed exchange rate and managed flexible exchange rate.
