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.

AGGREGATE DEMAND The total real expenditures on final goods and services produced in the domestic economy that buyers are willing and able to undertake at different price levels, during a given time period (usually a year). Aggregate demand, usually abbreviated AD, is an inverse relation between price level and aggregate expenditures. This is one half of the AS-AD (aggregate market) analysis. The other half is aggregate supply. Aggregate demand consists of four aggregate expenditures--consumption expenditures, investment expenditures, government purchases, and net exports--made by the four macroeconomic sectors--household, business, government, and foreign.
