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.

RETURNS TO SCALE Changes in production the occur when all resources are proportionately changed in the long run. Returns to scale come in three forms--increasing, decreasing, or constant based on whether the changes in production are proportionally more than, less than, or equal to the proportional changes in inputs. Returns to scale are the guiding principle for long-run production, playing a similar role that the law of diminishing marginal returns plays for short-run production.
