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.

MARKET STRUCTURE CONTINUUM The four common market structures, perfect competition, monopoly, monopolistic competition, and oligopoly, can be viewed as a continuum based on (1) differences in the number of firms in a market, (2) the relative size of each firm, and thus (3) the market control of each firm. Perfect competition lies at one end and monopoly at the other. Monopolistic competition is close to perfect competition and oligopoly is near monopoly. The essence of the continuum is that monopolistic competition blends into oligopoly, with no clear-cut line of separation.
