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.

Total factor cost per unit of factor input employed by a firm in the production of output, found by dividing total factor cost by the quantity of factor input. Average factor cost, abbreviated AFC, is generally equal to the factor price. However, using the longer term average factor cost makes it easier to see the connection to related terms, including total factor cost and marginal factor cost.
