I am an applied micro-economist in the area of public and environmental economics. I am generally interested in questions related to environmental economics, fiscal federalism, behavioral public economics and health economics. The main focus of my work lies on identifying the causal effects of public policy on people, firms and the environment. 

I currently serve as the dean of the Faculty of Business and Economics of the University of Basel, and as president of the environmental and resource economics chapter of the German Economics Association (AURÖ). I am a member of the CESifo Research Network, the CEPR and the university's Research Network Sustainable Future.
