Research

I am an assistant professor of economics at Freie Universität Berlin. I am also a research associate of the Berlin Research Associates Program (BERA), a faculty member of the Berlin Doctoral Program in Economics and Management Science (BDPEMS), a fellow of the Berlin Center for Consumer Policies (BCCP), a research affiliate of the Max Planck Institute for Research on Collective Goods, and a CESifo Affiliate.

Research Interests

As an applied microeconomic theorist, I study human behavior under uncertainty. In particular, I am interested in uncertainty that cannot be quantified exactly. In addition, I explore useful aspects of uncertainty and contractual arrangements mitigating the effects of uncertainty. As a researcher, I find these questions fascinating. I have studied communication of subjective information, strategic uncertainty, and uncertainty in contract enforcement. I use techniques drawn from game theory, mechanism design, decision theory, psychology, and probability theory.

Applications of my work include deterrence of insurance fraud and tax evasion, choices of unhealthy behavior, political competition, research contests and competition law.

Fields: Microeconomic Theory, Contract Theory, Behavioral Economics, Decision Theory, Mechanism Design
