´This paper aims to analize the role of personal identity indecision making. To this end, it starts by reviewing criticallythe growing literature on economics and identity. Consideringthe ambiguities that the concept of social identity poses, our proposalfocuses on the concept of personal...

Each of several exchange partners is the monopoly owner of a specific commoditywhich she can share with others. It is optimal to keep the own endowment, but allwould gain by mutual gift exchange. Participants play the game repeatedly in constantgroups (partner design) and can establish stable...

We adopt an evolutionary approach to investigate whether and when condi-tional cooperation can explain the voluntary contribution phenomenon oftenobserved in public goods experiments and in real life. Formally, conditionalcooperation is captured by a regret parameter describing how much an...

I suppose that people react with anger when others show themselves not to be minimally altruistic. With heterogeneous agents, this can account for the experimental results of ultimatum and dictator games. Moreover, it can account for the surprisingly large fraction of individuals who offer an...

We experimentally study behavior in a simple voting game where players have private information about their preferences. With random matching, subjects overwhelmingly follow the dominant strategy to exaggerate their preferences, which leads to inefficiency. We analyze an exogenous linking...

In this experimental study, involving subjects from Abu-Dis (West Bank), Chengdu (China), Helsinki (Finland), and Jerusalem (Israel), we test for a presentation bias in a two-person cooperation game. In the positive frame of the game, a transfer creates a positive externality for the opposite...

In diesem Beitrag geht es um subjektive Gerechtigkeitsvorstellungen, nicht Gerechtigkeit an sich, da erstere im Gegensatz zu letzterer empirisch feststellbar und handlungswirksam sind. Allerdings müssen ihre Folgen nicht nur gute sein. Gerechtigkeitsvorstellungen können erstens die...

This article defines in a precise manner three different mechanisms to achieve impartiality in distributive justice and studies them experimentally. We consider a first-person procedure, the Rawlsian veil of ignorance, and two third-party procedures, the impartial spectator and the ideal...

In standard rational choice modelling decisions are made according to given information and preferences. In the model presented here the 'information technology' of individual decision makers as well as their preferences evolve in a dynamic process. In this process decisions are made rationally...

A common feature of the literature on the evolution of preferences is that evolution favors nonmaterialistic preferences only if preference types are observable at least to some degree. We argue that this result is due to the assumption that in each state of the evolutionary dynamics some...
