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.

FOUR-SECTOR INJECTIONS-LEAKAGES MODEL A variation of the Keynesian injections-leakages model that adds the foreign sector to the three domestic sectors--the household sector, the business sector, and the government sector. This variation adds the foreign to the three domestic sectors (household, business, and government) in the three-sector model and provides an alternative to the four-sector aggregate expenditures (Keynesian cross). It provides the complete Keynesian representation of the macroeconomy, including the export-import interaction between the domestic economy and the foreign sector. Equilibrium is identified as the intersection between the S + T + M line and the I + G + X line. Two related variations are the two-sector injections-leakages model and the three-sector injections-leakages model.
