Die empirische Prüfung theoretischer Forschungsergebnisse wirft in der Ökonomie - wie bei jeder Sozialwissenschaft - Probleme auf. Anders als in den Naturwissenschaften können kaum volkswirtschaftliche Labors errichtet werden. Seit einigen Jahren nutzen Ökonomen die Erfahrungen der...

Recent theoretical work shows that folk theorems can be developed for infiniteoverlapping generations games. Cooperation in such games can be sustained as aNash equilibrium. Besides the efficient cooperative equilibrium there is alsothe inefficient non-cooperative equilibrium. This paper...

We examine an experimental gift exchange game in which the players can improve upon the unique no-gifts equilibrium through cooperative gift giving. The main feature of the study is that there are two different types of gift exchange, which we call simple and complex exchange, respectively....

This paper investigates the behaviour in repeated decision situations. The experimental study shows that subjects show low or no risk-aversion, but put very high value on the opportunity to sell the lottery in every stage of the decision problem. There is evidence that risk attitudes depend on...

We present an experiment where two players bargain with a third player. They can bargain either separately or form a joint venture to bargain collectively. Our theoretical benchmark solution predicts decentralized bargaining, as only one player has an interest in forming a joint venture....

We test in the laboratory the potential of evolutionary dynamics as predictor of actual behavior. To this end, we propose an asymmetric game -which we interpret as a borrowerlender relation-, study its evolutionary dynamics in a random matching set-up, and tests its predictions. The model...
