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.

SAVING SCHEDULE A table or chart that represents the relation between saving by the household sector and income. A saving schedule is commonly used for a basic, instructional presentation of aggregate saving activity by the household sector and is also used as a source of numbers for deriving the saving line. The key measures derived from the saving-income relation in the schedule are average propensity to save and marginal propensity to save. The consumption schedule is comparable, and more important, table for the relation between consumption and income.
