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.

MARGINAL PROPENSITY FOR GOVERNMENT PURCHASES The change in government purchases induced by a change in income or production (national income or gross domestic product). The marginal propensity for government purchases (abbreviated MPG) is another term for the slope of the government purchases line and is calculated as the change in government purchases divided by the change in income or production. The MPG plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part of the multiplier process. A related marginal measure is the marginal propensity to consume.
