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.

LONG-RUN AGGREGATE SUPPLY The total (or aggregate) real production of final goods and services available in the domestic economy at a range of price levels, during a period of time in which all prices, especially wages, are flexible, and have achieved their equilibrium levels. Long-run aggregate supply, commonly abbreviated LRAS, is one of two aggregate supply alternatives, distinguished by the degree of price flexibility. The other is short-run aggregate supply. Long-run aggregate supply is combined with aggregate demand, and often short-run aggregate supply, in the long-run aggregate market (or AS-AD) analysis used to analyze economic growth, business-cycle instability, unemployment, inflation, government stabilization policies, and related macroeconomic topics.
