Normensystemen kollektive Güter (oder Übel) bereitzustellen vermag. Kollektive Güter bilden typischerweise Antworten auf Kollektivgut-Probleme. Eine besonders wichtige Klasse solcher Kollektivgut-Probleme entsteht im Rahmen von so genannten "Allmenden" (oder "commons"). In diesem Beitrag...

Relying on the specific example of ultimatum bargaining experiments this paper explores the possible role of empirical knowledge of behavioural "norm(ative) facts" within the search for (W)RE – (Wide) Reflective Equilibria on normative issues. Assuming that "pro-social" behaviour...

This paper brings together views on choice making as have been developed in philosophy, psychology, and economics. Starting from specific examples the relative merits of different approaches are discussed. The conclusion that models of boundedly rational behavior are the future of social science...

Economists usually treat human behavior as being determined by the shadow of the future, while most other social scientists point to the shadow of the past. This paper considers experimental evidence relevant to the controversy and tries to reconcile both explanations of human behavior with each...

Standard economic explanations of good conduct in trade rely almost exclusively on future-directed extrinsic motivations induced by material incentives. But intrinsic motives to behave trustworthy and to punish untrustworthiness do support trade. In our model, intrinsically motivated players are...

This paper focuses on the uneasy alliance of rational choice and evolutionary explanations in modern economics. While direct evolutionary explanations of "optimality" rule out "purposeful" rational choice by assuming zero-intelligence and pure rational choice explanations leave no room for...

Medical doctors act as agents of their patients by either treating them directly or referring them to other more or differently specialized doctors, who thereby become "agents of agents". The main aim of this paper is to model central aspects of such two-layered agency relations in the medical...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

In this paper we consider conventions as regularities in behavior which help to solve coordination problems in a society. These problems can be formalized as non-cooperative games with several equilibria. We know that in such situations serious problems of equilibrium selection arise which...

Bereits im Jahre 1980 wählte Horst Albach einen spieltheoretischen und experimentellökonomischen Zugang zum Vertrauensproblem in der Ökonomik. Dieser Weg wird erneut beschritten. Es wird aufgezeigt, dass neuere spieltheoretische und experimentelle Arbeiten nicht nur die explanativen Grenzen...
