I am a Professor of Management at Goethe University Frankfurt. My research employs methods from game theory and experimental economics (lab and field experiments) to answer questions regarding the determinants and consequences of human decision-making and social interaction. I am particularly interested in understanding why humans (do not) cooperate and under what conditions cooperation in teams and groups can be sustained.
Recent papers study questions about measurement in economics, the role and impact of intrinsic motivation, the relationship between social preferences and collective-action outcomes, the function(s) of leadership, the determinants of (social, economic) institutions and organizational culture, as well the interaction between human and artificial agents.
I am currently director of the Frankfurt Laboratory for Experimental Economic Research (FLEX) and the Center for Leadership and Behavior in Organizations (CLBO), both at Goethe University. Since January 2020 I have been coordinator of the SAFE Experiment Center at the Leibniz Institute for Financial Research SAFE, where I am also Ombudsperson. In case you are interested, you can find some older videos about me here.
I am a research fellow at CEPR, CESifo, IZA, LIF-SAFE, and ZEF.
