OLS is bias and inconsistent when applied to a structural equation in a simultaneous equations system. 2SLS can be applied to SEMs equations, to solve the problem of endogenous explanatory variables, for each equation O b. + that is identified. It is the presence of an exogenous variable in one of the two-equation SEM (with a nonzero coefficient), not present in the other equation of the SEM, which makes the later equation identified. O d.
