AGGREGATE EXPENDITURE EQUATION: An equation indicating that aggregate expenditures (AE) are the sum of consumption expenditures (C), investment expenditures (I), government purchases (G), and net exports (X-M), stated as: AE = C + I + G + (X-M). This equation surfaces in the Keynesian economic income-expenditure model in the form of the aggregate expenditures line. However, it's also central throughout the study of macroeconomics, including aggregate demand and the measurement of gross domestic product.

CONSUMPTION FUNCTION A mathematical relation between consumption and income by the household sector. The consumption function can be stated as an equation, usually a simple linear equation, or as a diagram designated as the consumption line. This function captures the consumption-income relation that forms one of the key building blocks for Keynesian economics. The two key parameters of the consumption function are the intercept term, which indicates autonomous consumption, and the slope, which is the marginal propensity to consume and indicates induced consumption. Aggregate expenditures used in Keynesian economics are derived by adding investment, government purchases, and net exports to the consumption function.
