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.

MARGINAL PROPENSITY TO CONSUME: The proportion of each additional dollar of household income that is used for consumption expenditures. Or alternatively, this is the change in consumption expenditures due to a change in disposable income. Abbreviated MPC, the marginal propensity to consume is the slope of the consumption or propensity-to-consume line that forms the foundation for Keynesian economics. As such, it also takes center stage for the slope of the aggregate expenditure line and the multiplier effect. The sum of the marginal propensity to consume and the related concept, the marginal propensity to save, is equal to one.

SELF CORRECTION, MARKET The automatic process in which markets adjust from disequilibrium to equilibrium. With this self-correction process, the market price either increases or decreases in response to a shortage or a surplus to restore the balance between quantity demanded and quantity supplied. This process works automatically to achieve equilibrium without the need for outside intervention, such as government regulation.
