endogenous variable

a VARIABLE in an ECONOMIC MODEL that both affects and is itself affected by the relationship depicted in the model. For example, in the EQUILIBRIUM LEVEL OF NATIONAL INCOME model, an increase in consumption spending increases aggregate demand and raises the level of national income. By the same token, an increase in the level of national income (which results, say, from an increase in investment) will induce an increase in consumption spending. Compare EXOGENOUS VARIABLE.
