AE LINE: Another term for aggregate expenditure line, which is a line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

ORDINAL UTILITY The notion that utility--the satisfaction of wants and needs achieved through the consumption of goods and services--is measured by a ranking of preferences (first, second, third, etc.) that are only comparable on a relative basis. Ordinal utility does not presume that satisfaction is a measurable characteristic of a person, like height or weight, that can be compared against an established benchmark. The contrasting notion is cardinal utility, which is based on a numerical standard.
