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.

SAY'S LAW A principle of classical economics developed the French economist Jean-Baptiste Say that is commonly summarized as "supply creates its own demand." This law, also referred to as Say's "theory of markets" or "law of markets," indicates that the act of producing aggregate output generates a sufficient amount of aggregate income to purchase all of the output produced. This principle indicated that excess production or insufficient demand for production was unlikely to occur, at least for any extended period. When combined with flexible prices and saving-investment equality, Say's law further implied that an economy would achieve and maintain full employment of resources. This law was singled out by John Maynard Keynes in his critique of classical economics, but remains relevant in current macroeconomic analysis, reflected in the circular flow model.
