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.

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
