In France, in 2014, women's hourly wages were on average 14.4 % lower than men's. Beyond differentials in observed characteristics, is this gap explained by segregation of women in low-wage firms, or by gender inequality within a given firm? To answer that question, we apply the approach of...

This paper investigates the heterogeneity of ethnic employment gaps using a new single-index based approach. Instead of stratifying our sample by age or education, we study ethnic employment gaps along a continuous measure of employability, the employment probability minority workers would have...

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...

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 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...

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 relates changes in the high-skilled / medium-skilled relative wage of full-time male wage-earners in France with changes in supply and skill-biased demand shifts, including skill-biased technical change (SBTC). Using annual employer-employee administrative data matched with Census...

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...
