HHI: The common abbreviation for the Herfindahl-Hirshman index (or the Herfindahl index), which is 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 COST CURVE

A curve that graphically represents the relation between the total cost incurred by a firm in the short-run production of a good or service and the quantity produced. The total cost curve is a cornerstone upon which the analysis of short-run production is built. It combines all opportunity cost of production into a single curve, which can then be used with the total revenue curve to determine profit. The marginal cost curve, THE focal point for the analysis of short-run production, is derived directly from the total cost curve. The shape of the curve reflects increasing marginal returns at small quantities of output and decreasing marginal returns at larger quantities.
