This paper showcases studies that illustrate the potential of analyzing online job search data and of intervening in the online job search process. It presents the current insights and some open questions and highlights conditions under which some of the recent interventions are likely to improve market outcomes overall, rather than improving only the outcomes for the treated individuals.

American Economic Journal - Macroeconomics, 2022, 14(4), 1-97, with Michèle Belot and Paul Muller. In a field experiment, we study how job seekers respond to posted wages by randomly assigning wages randomly to pairs of otherwise similar vacancies in a large number of professions, which generates significantly more but not exclusive interest at higher wages.

joint with L.Brotherhood, C. Santos and M. Tertilt, accepted at Review of Economic Studies. This paper investigates the importance of the age composition for pandemic policy design in a framework with age heterogeneity, individual choice, and incomplete information, emphasizing the value of testing and testing capacity buildup. Optimal social policy follows an asymmetric approach by locking down the young relatively more than the old, and testing substantially lowers economic costs and laxer lockdown. We use the framework to provide systematic insights into pandemics caused by different viruses. Go to paper
