AGGREGATE EXPENDITURES 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.

INJECTIONS LINE A graphical representation of the relation between the level of aggregate production and one or more injections. The three injections (non-consumption expenditures on aggregate production) are investment expenditures, government purchases and exports. The injections line sequentially adds, or layers, each of these three expenditures depending on the number of sectors used in the analysis (two, three, or four). The slope of the injections line depends on which if any of the expenditures are induced by aggregate production. The injections line is combined with the leakages line (containing saving, taxes, and imports) in the Keynesian injections-leakages model.
