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.

INCREASING RETURNS TO SCALE A given proportional change in all resources in the long run results in a proportional greater change in production. Increasing returns to scale exists if a firm increases ALL resources--labor, capital, and other inputs--by a given proportion (say 10 percent) and output increases by more than this proportion (that is more than 10 percent). This is one of three returns to scale. The other two are decreasing returns to scale and constant returns to scale.
