We propose a new inverse probability weighting (IPW) estimator for moment condition models with missing data. Our estimator is easy to implement and compares favourably with existing IPW estimators, including augmented IPW estimators, in terms of efficiency, robustness, and higher-order bias. We...

The author considers a class of models that generalizes the popular mixed proportional hazard model for duration data: the generalized accelerated failure-time model. He shows that the generalized accelerated failure-time model is nonparametrically identified (up to a normalization). He then...

We investigate the choice of the bandwidth for the regression discontinuity estimator. We focus on estimation by local linear regression, which was shown to have attractive properties (Porter, J. 2003, "Estimation in the Regression Discontinuity Model" (unpublished, Department of Economics,...
