Marie-Renée Andreescu

I am a PhD Candidate in Economics at the Paris School of Economics under the supervision of Eric Maurin. I am affiliated to the PSE Labor Chair.

In Spring 2026, I visited HEC Lausanne, hosted by Rafael Lalive. 

I am on the 2026–2027 academic job market.

My research lies at the intersection of labour economics, public economics, and the economics of technological change. I study how labour-market institutions, recruitment practices, and new technologies affect firms and workers, using administrative data, experimental and quasi-experimental methods.

For more information, here is my CV ! 

I am also the Eastern Europe and Russia Coordinator at the World Inequality Lab.

I have a new working paper on Gen AI and the change in demand for skills it implies. You can find it here !

Firms face increasingly large applicant pools: more candidates offer more opportunities to find a suitable worker, but also more applications to assess. This paper studies whether expanding employers’ choice sets improves recruitment or makes decisions harder. Using quasi-random assignment of employers to caseworkers who screen applications in the French Employment Service, I estimate the effect of an additional candidate reaching the recruiter. One additional candidate raises the probability of a contract proposal within three months by 10% and of a hire within six months by 7%, with strongly diminishing returns. Longer shortlists have lower average fit but contain more suitable candidates, with no detectable decline in the observable quality of recruited workers. Where candidates are scarce, firms value an extra candidate more but convert fewer proposals into hires.
