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.

PRODUCTION POSSIBILITIES SCHEDULE

A table of numbers that illustrates the production possibilities of an economy--the alternative combinations of two goods that an economy can produce with given resources and technology. A production possibilities schedule illustrates that the economy must give up the production of one good to produce another good--the basic economic notion of opportunity cost. A production possibilities schedule is also used to derive the highly useful production possibilities curve (or frontier).
