This paper concerns estimation and inference in simultaneous limited dependent variable or simultaneous qualitative dependent variable models. We discuss the implications of the coherency condition which is required to ensure a unique implicit reduced form in such nonlinear models. A number of model specifications are examined, including the Simultaneous Probit, Simultaneous Tobit, and Simultaneous Generalised Selectivity models, and we consider the usefulness of a conditional maximum likelihood (CML) methodology. We obtain a simple consistent estimator which is a natural counterpart to the CML estimator for standard simultaneous models. An application to a structural model of household labo..
