In this study, we use an allocation game to study the effects of group identity and group size on in-group favouritism when the person's own payoff is not affected by her decision. We first show that in a triadic setting when the subjects are asked to allocate a fixed amount of resource between...

While numerous experiments demonstrate how pro-sociality can influence economic decision-making, evidence on explicitly anti-social economic behavior has thus far been limited. In this paper we investigate the importance of spite in experimental rent-seeking contests. Although, as we show,...
