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.

THREE-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that includes the three domestic sectors--the household sector, the business sector, and the government sector. This model provides an alternative to the three-sector aggregate expenditures (Keynesian cross) analysis of government stabilization policies, especially how fiscal policy changes in government purchases and taxes can be used to close recessionary gaps and inflationary gaps. Equilibrium is identified as the intersection between the S + T line and the I + G line. Two related variations are the two-sector injections-leakages model and the four-sector injections-leakages model.
