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.

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.
