Welcome to my webpage !

I am a CNRS researcher at Centre d'Economie de la Sorbonne.

I was a junior researcher at Sciences-Po LIEPP in 2014-2015 and a postdoctoral fellow at Université catholique de Louvain in 2012-2014.

My research interests focus on discrimination against African immigrants in France and against African-Americans
in the US. I analyze how racial discrimination affects the economic situation of these two minority groups in imperfect labor market models, using search models with matching frictions. I use individual-level data to study the impact of racial prejudice on labor market outcomes of minorities, such as employment, wages and probability of occupying a job in contact with consumers.

'Hate at First Sight’: Evidence of Consumer Discrimination against African-Americans in the US, Labour Economics, Vol 46, 2017

Customer Discrimination and Employment Outcomes: Theory and Evidence from the French Labor Market, [New Version] [Online Appendix]. With PPh. Combes, B. Decreuse and A. Trannoy, Forthcoming in the Journal of Labor Economics, IZA Discussion Paper No. 8150, April 2014.
The paper investigates the link between the over-exposure of African immigrants to unemployment in France and their under-representation in jobs in contact with customers. We build a two-sector matching model with ethnic sector-speci c preferences, economy-wide employer discrimination, and customer discrimination in jobs in contact with customers. The outcomes of the model allow us to build a test of ethnic discrimination in general and customer discrimination in particular. We run the test on French individual data in a cross-section of local labor markets (Employment Areas). Our results show that there is both ethnic and customer discrimination in the French labor market.

’Can’t get enough’: Prejudice, Contact-jobs and the black-white wage gap in the US. IZA DP No. 8006, February 2014
The wage gap between African-Americans and whites is substantial in the US and has slightly narrowed over the past 30 years. There is reason to believe that discrimination driven by prejudice plays a part in explaining this residual wage gap. Whereas racial prejudice has substantially declined over the past 30 years, the wage differential has slightly converged overtime. This ‘prejudice puzzle’ raises other reasons in explaining the absence of strong convergence of this racial gap. In this paper, I assess the impact which of the boom of jobs in contact with customers has on blacks'earnings. I develop a search-matching model to predict the negative impact which of the share of these contact jobs has on blacks’ earnings in the presence of customer discrimination. Using the US Census, the General Social Survey and the Occupation Information Network, I find that black men’s relative earnings are lower in areas where shares of prejudiced individuals and of contact-jobs are high. I also estimate that the decreased exposure to racial prejudice is associated with a higher convergence of the residual earnings gap, whereas the expansion of contact-jobs partly explains its persistence.
