Research Project title: Cooperation: Rational vs. Social

Research abstract
Is cooperation rational? On one account, which is the dominant one in the social sciences and in decision theory – based on “rational choice” based analyses of cooperation – cooperation is seen as being frequently irrational, even when all parties acting cooperatively would benefit each of them. This is because in some situations (for instance, the famous prisoner’s dilemma) acting cooperatively seems to require acting against one’s own interest, conceived in terms of concepts such as the “dominant strategy”. The “rational” justification for acting cooperatively in such situations has generally, in this tradition, been based upon the idea that players faced with the same situation repeatedly would weigh the benefits of deviating from cooperation in the short term against the losses in the long term from other parties withdrawing their cooperation as a result. Cooperation sustained on the basis of such a calculation has been referred to in game theory as “trusting” behavior, but this seems a misnomer, since it appears to be merely “an encapsulation of self-interest”. As such, it cannot explain the decision to cooperate in a situation such as the (one shot) prisoner’s dilemma, in which standard rational choice theory would insist that cooperation is contrary to self-interest. What, then, is trust, and what role does it have to play in cooperation? Can it also provide explanatory resources that go beyond the traditionally conceived forms of “rational choice” theory? We might hypothesize that trust in the context of cooperation is defined by a reliance on a belief that others will act cooperatively (in a manner that may or may not be contingent upon one’s own actions). For cooperation to be underpinned by trust, then, is for the cooperating agents to possess a belief that others will cooperate, and for that belief to help to sustain their own acts of cooperation. Cooperation understood in this way is compatible with the game theoretic understanding of cooperation arising in repeated play on the basis of self-interest but is in no way dependent on that narrow idea. The question of how to explain cooperation (if it is thought to need explanation) is in this perspective displaced onto another question, which is that of how it is that trust comes to exist and to be warranted. The project develops and elaborates these ideas.


Research project title: The Predicament of Economics

Research abstract
During my stay I will investigate the ‘predicament of economics’, in particular the underlying sources of difficulties in establishing agreed upon and ‘law-like’ economic knowledge, and what implications this has for our understanding of the status of economic knowledge and of the role it can or should play in society.
The project thus straddles the methodology, the sociology and politics of social science to ask how and why it is that the discipline, looked to in order to provide answers to pressing questions of social explanation and of policy, often does not do so fails to do so in a manner that many could consider to be satisfactorily, and is instead y, seemingly characterized by permanent internal conflicts, and the reign of ideology, fads and fashions, and some notable predictive and explanatory failures. The project explores the forces and factors operating on the discipline to deflect or prevent it from better serving its social mission and explores the predicament of economists, asking whether certain debates can ever reasonably be expected to be resolved or whether their continuation is a manifestation of politics in another form. If there is a way forward that might permit the discipline to become both more reason-bound and more faithful to society, what is it?

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.
