We develop and evaluate experimentally a novel tool that redesigns the job search process by providing tailored advice at low cost. We invited jobseekers to our computer facilities for twelve consecutive weekly sessions to search for real jobs on our web interface. For one-half, instead of relying on their own search criteria, we use readily available labour market data to display relevant alternative occupations and associated jobs. The data indicate that this broadens the set of jobs they consider and increases their job interviews especially for participants who otherwise search narrowly and have been unemployed for a few months.

Do the Long-term Unemployed Benefit from Automated Occupational Advice during Online Job Search?
with Michèle Belot and Paul Muller, Economic Journal, 2026, Vol 136, 184–206. In a randomized field experiment, we provide personalized suggestions about suitable alternative occupations to long-term unemployed job seekers in the UK. Effects on the primary pre-registered outcomes of "finding a stable job" and "reaching a cumulative earnings threshold" are positive and large (between 20% to 40% after 9 months). Go to paper

Journal of the European Economic Association, 2022, 20(6), 2317–2352. This paper showcases studies that illustrate the potential of analyzing online job search data and of intervening in the online job search process, 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.
