The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent, if an interaction of the outcome variable with an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood (FIML) estimator...

Over the past years, public smoking bans have been introduced in most European countries. Unlike elsewhere, in Germany such bans were introduced at state level at different points in time, which provides important intra-country regional variation that can be exploited to identify the effects of...

This analysis shows that multivariate generalizations to the classical Heckman (1976, 1979) two-step estimator that account for cross-equation correlation and use the inverse Mills ratio as correction term are consistent only if certain restrictions apply to the true error-covariance structure....

This study analyses a parametric estimator for a system of equations with limited dependent variables that was recently proposed. Its performance is compared with those of alternative estimation procedures using Monte Carlo methods. The comparison shows that this new estimator is less efficient...
