Point-identifying semiparametric sample selection models with no excluded variable
Kim, Dongwoo; Lee, Young Jun - 2025
Sample selection is pervasive in applied economic studies. This paper develops semiparametric selection models that … selection bounds, while ensuring point identification. Simulation evidence confirms its excellent finite-sample performance. We …

Finite sample bias corrected IV estimation for weak and many instruments
Harding, Matthew C.; Hausman, Jerry A.; Palmer, … - 2015
This paper considers the finite sample distribution of the 2SLS estimator and derives bounds on its exact bias in the …-type estimators. After deriving a finite sample unbiased k-class estimator, we introduce a double k-class estimator based on Nagar …

Quantile selection models : with an application to understanding changes in wage inequality
Arellano, Manuel; Bonhomme, Stéphane - 2015
We propose a method to correct for sample selection in quantile regression models. Selection is modelled via the …

Optimal data collection for randomized control trials
Carneiro, Pedro; Lee, Sokbae; Wilhelm, Daniel - 2019
In a randomized control trial, the precision of an average treatment effect estimator and the power of the corresponding t-test can be improved either by collecting data on additional individuals, or by collecting additional covariates that predict the outcome variable. To design the...
