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.

LONG RUN, MACROECONOMICS In terms of the macroeconomic analysis of the aggregate market, a period of time in which all prices, especially wages, are flexible, and are able to achieve equilibrium levels. This is one of two macroeconomic time designations; the other is the short run. Long-run wage and price flexibility means that ALL markets, including resource markets and most notably labor markets, are in equilibrium, with neither surpluses nor shortages. Wage and price flexibility and the resulting resource market equilibria are the reason for the vertical long-run aggregate supply curve.
