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.

MONOPOLY: A market structure characterized by a single seller of a unique product with no close substitutes. This is one of four basic market structures. The other three are perfect competition, oligopoly, and monopolistic competition. As the single seller of a unique good with no close substitutes, a monopoly firm essentially has no competition. The demand for a monopoly firm's output is THE market demand. This gives the firm extensive market control--the ability to control the price and/or quantity of the good sold--making a monopoly firm a price maker. However, while a monopoly can control the market price, it can not charge more than the maximum demand price that buyers are willing to pay. See also | market structure | perfect competition | oligopoly | monopolistic competition | market control | price maker | marginal cost | demand curve | market failure | monopoly characteristics | monopoly and demand | monopoly and efficiency | monopoly profit | monopoly and perfect competition | monopsony | natural monopoly | inefficiency |

AUTONOMOUS EXPENDITURES Expenditures on aggregate production by the four macroeconomic sectors that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in these expenditures. Each of the four aggregate expenditures--consumption, investment expenditures, government purchases, and net exports--have an autonomous component. Autonomous expenditures are affected by the ceteris paribus aggregate expenditures determinants and are measured by the intercept term of the aggregate expenditures line. The alternative to autonomous expenditures are induced expenditures, expenditures which do depend on income.

[What's This?]
Today, you are likely to spend a great deal of time flipping through the yellow pages hoping to buy either a flower arrangement with anything but tulips for your grandfather or a birthday greeting card for your mother that doesn't look like a greeting card. Be on the lookout for mail order catalogs with hidden messages.
