Dummy Endogenous Variables in a Simultaneous Equation System
James J. Heckman · RePEc: Research Papers in Economics · 1977
This paper considers the formulation and estimation of simultaneous equation models with both discrete and continuous endogenous variables. The statistical model proposed here is sufficiently rich to encompass the classical simultaneous equation model for continuous endogenous variables and more recent models for purely discrete endogenous variables as special cases of a more general model.
