This paper uses a French reform to evaluate the impacts of price regulation on general practitioners (GP) care provision, fees, and income. This reform has restricted, since 1990, the conditions self-employed GPs have to fulfill to be allowed to over-bill. We exploit 2005 and 2008 Public Health...

This paper investigates how the ethnic gap in employment rates varies across skill levels. Instead of stratifying our sample in many dimensions (age groups, education levels...), we introduce a method that allows us to study the heterogeneity of binary outcomes with respect to all covariates at...

We construct finite-sample distribution-free tests and confidence sets for the parameters of a linear median regression, where no parametric assumption is imposed on the noise distribution. The set-up studied allows for non-normality, heteroscedasticity, non-linear serial dependence of unknown...

We construct finite-sample distribution-free tests and confidence sets for the parametersof a linear median regression where no parametric assumptions are imposed on thenoise distribution. The setup we consider allows for nonnormality, heteroskedasticityand nonlinear serial dependence in the...

We propose estimators for the parameters of a linear median regression without any assumption on the shape of the error distribution including no condition on the existence of moments allowing for heterogeneity (or heteroskedasticity) of unknown form, noncontinuous distributions, and very...

We propose estimators for the parameters of a linear median regression without any assumption on the shape of the error distribution – including no condition on the existence of moments – allowing for heterogeneity (or heteroskedasticity) of unknown form, noncontinuous distributions, and...
