This paper revisits and extends the experiment on the solidarity game by Selten and Ockenfels (1998). We replicate the basic design of the solidarity game and extend it in order to test the robustness of the 'fixed total sacrifice' effect and the applied strategy method. Our results only...

The study of gender differences in social preferences has shown mixedresults, preventing economists and other social scientists from drawingdefinitive conclusions on this topic. Several original investigations andexperimental reviews have hypothesized that the main reason of this heterogeneityof...

We perform an experimenta linvestigation using a dictator game inwhich individuals must make a moral decision —to give or not to give anamount of money to poor people in the Third World. A questionnaire inwhich the subjects are asked about the reasons for their decision showsthat, at least in...

´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...

Why is it that well-intentioned actions can create persistent conflicts? While norms are widely regarded as a source for cooperation,this article proposes a novel theory in which the emergence of normscan be understood as a bargaining process in which normative conflicts explain the nally...

We study two person-betting games with inconsistent commonly know beliefs, using an experimentalapproach. In our experimental games, participants bet against one another, each bettorchoosing one of two possible outcomes, and payoff odds are know at the time bets are placed.Bettors’ beliefs are...

Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

We study interaction effects between intra-firm conflicts and interfirm competitionon a duopolistic market with seller firms employing one or more agents and imple-menting tournament incentives. We show that inter-firm competition leads to higherincentive intensity, higher efforts and output...

We experimentally investigate how affective processes influence proposers’and responders’ behaviour in the Ultimatum Game. Using a dualsystemapproach, we tax cognitive resources through time pressure andcognitive load to enhance the influence of affective processes on behaviour.We find that...

Using a symmetric 2-person prisoners’ dilemma as the base game, each playerreceives a signal for the number of rounds to be played with the same partner.The actual number of rounds (the length of the supergame) is determined bythe maximal signal where each player expects the other’s signal...
