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.

CLASSICAL ECONOMICS A theory of economics, especially directed toward macroeconomics, based on the unrestricted workings of markets and the pursuit of individual self interests. Classical economics relies on three key assumptions--flexible prices, Say's law, and saving-investment equality--in the analysis of macroeconomics. The primary implications of this theory are that markets automatically achieve equilibrium and in so doing maintain full employment of resources without the need for government intervention. Classical economics emerged from the foundations laid by Adam Smith in his book An Inquiry into the Nature and Causes of the Wealth of Nations, published in 1776. Although it fell out of favor in the 1930s, many classical principles remain important to modern macroeconomic theories, especially aggregate market (AS-AD) analysis, rational expectations theory, and supply-side economics.
