Blaming the Exogenous Environment? Conditional Efficiency Estimation with Continuous and Discrete Environmental Variables
De Witte, K.; Kortelainen, Mika - 2009
British pupils from the OECD Pisa data set. The results show that several exogenous discrete factors have a significant effect …

Testing the "separability" condition in two-stage nonparametric models of production
Daraio, Cinzia; Simar, Léopold; Wilson, Paul W. - 2015
Simar and Wilson (J. Econometrics, 2007) provided a statistical model that can rationalize two-stage estimation of technical efficiency in nonparametric settings. Two-stage estimation has been widely used, but requires a strong assumption: the second-stage environmental variables cannot affect...

Estimating alternative technology sets in nonparametric efficiency analysis : restriction tests for panel and clustered data
Neumann, Anne; Nieswand, Maria; Schubert, Torben - 2016
Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive-based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

Exact tests on returns to scale and comparisons of production frontiers in nonparametric models
Rønn-Nielsen, Anders; Kronborg, Dorte; Asmild, Mette - 2019
When benchmarking production units by non-parametric methods like data envelopment analysis (DEA), an assumption has to … frontiers across samples of producers. Until now, no exact tests for examining returns to scale assumptions in DEA, or for test … test for the hypothesis of constant returns to scale in DEA.

Additive nonparametric regression in the presence of endogenous regressors
Ozabaci, Deniz; Henderson, Daniel J.; Su, Liangjun - 2014
In this paper we consider nonparametric estimation of a structural equation model under full additivity constraint. We propose estimators for both the conditional mean and gradient which are consistent, asymptotically normal, oracle efficient and free from the curse of dimensionality. Monte...

Estimating Returns to Education When the IV Sample is Selective
Wang, Le - 2013
The literature estimating returns to education has often utilized spousal education and parental education as instrument variables (IV). However, due to usual survey designs, both IVs are available only for the individuals whose spouse or parents are present in the same household. The IV...
