THREE-SECTOR AGGREGATE EXPENDITURES LINE: A graphical depiction of the relation between aggregate expenditures by the three domestic macroeconomic sectors (household, business, and government) and the level of aggregate income or production. The three-sector aggregate expenditures line combines consumption expenditures, investment expenditures, and government purchases. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for marginal propensities of the other expenditures that are assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the two-sector aggregate expenditures line and the four-sector aggregate expenditures line.

GOOD TYPES The economy produces four distinct types of goods based on two key characteristics -- consumption rivalry and nonpayer excludability. Consumption rivalry arises if consumption of a good by one person prevents another from also consuming. Nonpayer excludability means potential consumers who do not pay for a good can be excluded from consuming. Private goods are rival in consumption and easily subject to the exclusion of nonpayers. Public goods are nonrival in consumption and the exclusion of nonpayers is virtually impossible. Near-public goods are nonrival in consumption and easily subject to exclusion. Common-property goods are rival in consumption and not easily subject to exclusion. Private goods can be efficiently exchanged through markets. Public, near-public and common-property goods cannot, but require some degree of government involvement for efficiency.
