The research presented in this video tackles the old philosophical question on the reasons for social order with the means of modern economics. As HARTMUT KLIEMT elaborates, the rational choice assumption – that human behavior is guided by looking at causal consequences – cannot explain sufficiently why social order exists, because it does not account for rule-following behavior. Thus he shows that economic models of law or politics need to be improved by integrating rule-following behavior.


Hartmut Kliemt is Professor of Philosophy & Economics at the Frankfurt School of Finance and Management. He was Professor for Practical Philosophy at the Gerhard Mercator University Duisburg for two decades.

Kliemt follows the English model of the “philosopher economist“ by working interdisciplinary in the fields of philosophy and economy using methods of decision and game theory. His research focuses on health ethics and economics, methodology of the practical sciences (such as medicine, business administration, law), and constitutional political economics. Hartmut Kliemt is one of the leading philosopher economists in Germany and worldwide.
