AGGREGATE EXPENDITURE 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.

MARGINAL REVENUE PRODUCT The change in total revenue resulting from a unit change in a variable input, keeping all other inputs unchanged. Marginal revenue product, usually abbreviated MRP, is found by dividing the change in total revenue by the change in the variable input or by multiplying marginal physical product by marginal revenue. This is also termed value of the marginal product. Marginal revenue product is a key concept for understanding the demand for productive inputs.
