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.
