In their research, the members of the Chair of Public Economics apply microeconometric methods to answer policy relevant questions in the areas labor, family, environmental and health economics. They work with registry data, survey data, self-collected data from experiments, and newly digitized historical data. Current projects include work on the effects of speed limit monitoring campaigns on road safety, on attitudes towards carbon pricing, or on the determinants and persistence of energy poverty, as well as economic history projects on the effects of birth control clinics on fertility and mortality in the U.S. in the early 20th century or the effects of the Spanish flu on elections in the Weimar Republic.
