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 TOTAL COST

The opportunity cost incurred by all of the factors of production used in the long run (when all inputs are variable) by a firm to produce a good or service, including wages paid to labor, rent paid for the land, interest paid to capital owners, and a normal profit earned by entrepreneurs. Unlike short-run total cost, long-run total cost cannot be separated into fixed cost and variable cost. In the long run, all inputs are variable, so all cost is variable.
