INVESTMENT LINE A graphical depiction of the relation between investment expenditures by the business sector and the economy's aggregate level of income or production. This relation plays a key role in the study of Keynesian economics. A investment line is characterized by vertical intercept, which indicates autonomous investment, and slope, which is the marginal propensity to invest and indicates induced investment. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the investment line onto the consumption line, then adding government purchases and net exports to this stack.
