I'm an economist of the French National Institute of Statistics and Economic Studies (Insee) and an associate researcher at CRED Université Paris 2.
My interests are at the intersection of public finance, behavioral economics and unemployment insurance.
I am currently employed by the statistical office of the French Ministry of Labor (Dares).
Public Finance with Behavioural Agents, Elements in Behavioural and Experimental Economics. Cambridge: Cambridge University Press, 2022.
Recent developments in behavioural economics have deeply influenced the way governments design public policies. They give citizens access to online simulators to cope with tax and benefits systems and increasingly rely on nudges to guide individual decisions. The recent surge of interest in Behavioural Public Finance is grounded on the conviction that a better understanding of individual behaviours could improve predictions of tax revenue and help design better-suited incentives to save for retirement, search for a new job, go to school or seek medical attention. Through a presentation of the most recent developments in Behavioural Public Finance, this Element discusses the way Behavioural Economics has improved our understanding of fiscal policies.
Behavioral Cross-Influence of a Shadow Tax Bracket: Evidence from Bunching where Income Tax Liabilities start, accepted at Journal of Public Economics.
Tax filers who neglect a tax collection minimum perceive a shadow tax bracket below the Tax Collection Threshold (TCT) where income tax liabilities start. They end up bunching at an irrelevant Taxation Threshold (TT). Using dynamic adjustments to this misperceived schedule, I estimate a significantly positive behavioral cross-influence of the TT. Standard analysis restricted to effective incentives would underestimate the elasticity of taxable income by 60%.
The Take-up of Unemployment Benefit Extensions (with B. Boutchenik)
Receiving an informative mailing upon unemployment benefit exhaustion stimulates job certification, ultimately increasing potential benefit duration. This intervention provided first-time claimants with pieces of information they used to miss, whereas it acted as a reminder for the more experienced ones.
