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.

INDUCED NET EXPORTS Net exports by the foreign sector that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in net exports. Induced net exports reflect the induced relation between imports and income, which means net exports decline as income increases. They are measured by the negative of the marginal propensity to import (MPM) and are reflected by the negative slope of net exports line. The alternative to induced net exports is autonomous net exports, which do not depend on income.
