EXPORTS LINE

A graphical depiction of the relation between exports sold to the foreign sector and the 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 exports line is horizontal which indicates that exports are totally autonomous, with no induced component. 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.
