Presentation: 

I am a PhD candidate in Economics at CREST (Ecole polytechnique, Institut Polytechnique de Paris) working under the supervision of Pierre Boyer and Antoine Bozio.

My research interests are in public economics and applied microeconomics.

I study how public policies affect the economy and how to improve their design, using empirical and theoretical approaches. I focus on the role of imperfect information and other friction in shaping how people perceive and react to policies.

Raising Take-up of Welfare Programs: Evidence from a Large French Reform
Abstract: Imperfect take-up of public policies has been a growing concern for modern welfare states. This paper examines the effect on claiming behaviors of two types of interventions, an increase in benefit generosity and an information provision. Exploiting exhaustive administrative data and a large welfare reform of an in-work benefit in France as a quasi-experiment, I find that information provision acted as an effective tool to raise participation while benefit generosity did not. Take-up responses to changes in monetary incentives to claim are not significant and small in magnitude, with an implied take-up elasticity of about 0.1. Instead, raising global awareness about the program led to an increase by 15% of the take-up rate. The marginal enrollee is more likely to be a childless single male but has on average lower income than the usual entrant. Drawing on the empirical findings, I build a theoretical framework to assess the welfare implications of policy interventions that can raise take-up and apply it to the French welfare reform.
