DETERMINANT: A ceteris paribus factor that is held constant when a curve is constructed. Changes in these factors then cause the curve to shift to a new location. The most common determinants are demand determinants for the demand curve (income, preferences, other prices, buyers' expectations, and number of buyers) and supply determinants for the supply curve (resource prices, technology, other prices, buyers' expectations, and number of buyers). Other common curves and their determinants include: production possibilities curve (technology, education and the quantities of labor, capital, land, and entrepreneurship); aggregate demand curve (the four aggregate expenditures of consumption, investment, government purchases, and net exports); and short-run average cost curve (technology, wages, and other production cost).

CONCENTRATION RATIOS A family of measures of the proportion of total output in an industry that is produced by a given number of the largest firms in the industry. The two most common concentration ratios are for the four largest firms and the eight largest firms. The four-firm concentration ratio is the proportion of total output produced by the four largest firms in the industry and the eight-firm concentration ratio is proportion of total output produced by the eight largest firms in the industry. Concentration ratios are commonly used to indicate the degree to which an industry is oligopolistic and the extent of market control of the largest firms in the industry. A related measure is the Herfindahl index.
