FOUR-SECTOR AGGREGATE EXPENDITURES LINE

A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. The four-sector aggregate expenditures line combines consumption expenditures, investment expenditures, government purchases, and net exports. 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 three-sector aggregate expenditures line.
