PERFECT COMPETITION, FACTOR MARKET ANALYSIS: The analysis of a factor market characterized by perfect competition indicates that each buyer maximizes profit by equating marginal revenue product to the factor price. This achieves an efficient allocation of resources and provides a benchmark for analyzing other factor market structures, including monopsony, monopoly, and bilateral monopoly.

AGGREGATE EXPENDITURES EQUATION:

An equation that summarizes the four aggregate expenditures on gross domestic product by the four macroeconomic sectors. In the study of Keynesian economics, this equation is commonly used to summarize the demand side of the macroeconomy. The aggregate expenditures equation actually comes in three different versions depending on how many of the four sectors and their expenditures are included.
The aggregate expenditures equation is the sum of the four aggregate expenditures (consumption expenditures, investment expenditures, government purchases, and net exports). This equation provides a short-hand notion that summarizes the demand side of the economy.

The general aggregate expenditures equation is:

AE=C+I+G+(X-M)
where: AE is aggregate expenditures, C is consumption expenditures, I is investment expenditures, G is government purchases, and X-M is net exports, exports (X) minus imports (M).

This particular version of the aggregate expenditures equation is for all four macroeconomic sectors (household sector, business sector, government sector, and foreign sector). In some circumstances reduced versions, with fewer sectors, are more useful. A three-sector version that includes the household, business, and government sectors is:

AE=C+I+G
And the simplest aggregate expenditures equation is for the two private sectors--household and business. It is specified as:
AE=C+I
