Estimation in a Class of Simultaneous Equation Limited Dependent Variable Models.

Estimation of simultaneous-equation, limited dependent variable models is considered. The minimum Chi-squared method is used to compare the asymptotic relative efficiency of marginal and new conditional maximum likelihood estimators for this class of models. Efficient minimum Chi-squared estimation procedures are described. A two-step algorithm, based on a conditional maximum likelihood estimator, provides a natural framework for both computing a linearized and locating the joint maximum likelihood estimator. The unimodality of the simultaneous-equation, tobit likelihood function is proved and this model is used to illustrate the empirical application of some of the estimators considered in the paper.
