Jonas Meier is an econometrician interested in both, theoretical an applied topics. Before Jonas joined UvA in September 2022, he never really escaped his hometown, the city of Bern in Switzerland where he obtained all his academic degrees. In his theoretical work, Jonas studies the behavior of semi-parametric estimators modeling this distribution. Among others, these methods provide many appealing ways to address heterogeneous treatment effects. Especially in the case of policy analysis, this may contribute to a better understanding of the underlying mechanisms. In addition, Jonas works on several applied topics in micro-econometrics, for instance, in health and transport economics.
