The reduced form equations for the two endogenous variables included in (2.1) may be written as Y = ZlIl + Z2I2 + V, (2.2) WebEndogenous variables are used in econometrics and sometimes in linear regression. They are similar to (but not exactly the same as) dependent variables. Endogenous variables have values that are determined by other variables in the system (these “other” variables are called exogenous variables).
