AGGREGATE EXPENDITURE LINE: 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.

UTIL A hypothetical unit of measurement of utility that is commonly used by economists to present hypothetical information about utility and consumer demand theory. The util measurement unit was developed as a convenient way to illustrate and discuss concepts such as total utility, marginal utility, and the law of diminishing marginal utility. However, because utility is not a measurable characteristic, the util does represent an actual unit of measurement, such as inches or pounds.
