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.

AGGLOMERATION ECONOMIES: A reduction in production cost the results when related firms locate near one another. Firms can be related as competitors in the same industry, by using the same inputs, or through providing output to the same demographic group. The fashion industry, for example, experiences agglomeration economies because they can share specialized inputs (photographers, models) that would be too expensive to employ full time. Retail stores have agglomeration economies when located in shopping malls because they have access to a large group of potential customers with lower advertising cost. Agglomeration economies is given as one of the primary reasons for the emergence of urban areas.

INTERCEPT, AGGREGATE EXPENDITURES LINE The intercept of the aggregate expenditures line indicates autonomous expenditures, aggregate expenditures that do not depend on the level of income or production. This can be thought of as aggregate expenditures that the four macroeconomic sectors (household, business, government, and foreign) undertake regardless of the state of the economy. Autonomous expenditures are affected by the aggregate expenditures determinants, which cause a change in the intercept and a shift of the aggregate expenditures line.
