CARDINAL UTILITY: A measure of utility, or satisfaction derived from the consumption of goods and services, that can be measured using an absolute scale. Cardinal utility exists if the utility derived from consumption is measurable in the same way that other physical characteristics--height and weight--are measured using a scale that is comparable between people. There is little or no evidence to suggest that such measurement is possible and is not even needed for modern consumer demand theory and indifference curve analysis. Cardinal utility, however, is often employed as a convenient teaching device for discussing such concepts as marginal utility and utility maximization.

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.
