Sven A. Hartmann is a postdoctoral researcher at Trier University and the Institute for Labour Law and Industrial Relations in the European Union (IAAEU).

He studies how institutional environments and access to information shape economic beliefs, human capital investment, and labor market behavior. His work is primarily empirical: it relies on quasi-experimental designs to identify causal effects and draws on survey experiments and theoretical models to examine underlying mechanisms.

Sven joined the IZA@LISER network in November 2026.
