We give semiparametric identification and estimation results for econometric models with a regressor that is endogenous …-identified and characterize the identification sets. Second, we propose novel estimation and inference methods for this true value …. These estimation and inference methods are of independent interest and apply to any problem possessing the sensitivity …

We introduce two new Stata commands for the estimation of an ordered response model with sample selection. The opsel … estimation of discrete response models. Compared to the other SNP estimators, our routine is relatively faster because it is … programmed in MATA. In addition, we provide new post-estimation routines to compute linear predictions, predicted probabilities …
