IMPORTS LINE: A graphical depiction of the relation between imports bought from the foreign sector and the domestic economy's aggregate level of income or production. This relation is most important for deriving the net exports line, which plays a minor, but growing role in the study of Keynesian economics. An imports line is characterized by vertical intercept, which indicates autonomous imports, and slope, which is the marginal propensity to import and indicates induced imports. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the net exports line, derived as the difference between the exports line and imports line, onto the consumption line, after adding investment expenditures and government purchases.

DERIVATION, AGGREGATE EXPENDITURES LINE An aggregate expenditures line, a graphical depiction of the relation between aggregate expenditures and the level of aggregate income or production, can be derived by sequentially adding expenditures by the four macroeconomic sectors (household, business, government, and foreign). This derivation process begins with the consumption line, then adds investment, government purchases, and finally net exports. The process actually generates three alternative aggregate expenditures lines based on the number of sectors included (two sector, three sector, and four sector).
