We study how conflict in contest games is influenced by rival parties being groups and by group members being able to punish each other. Our motivation stems from the analysis of sociopolitical conflict. The theoretical prediction is that conflict expenditures are independent of group size and...

We introduce the experimental vendetta game. Two groups of four players each interact over ten identical rounds. In each round each player decides whether or not to reduce the payoff of each member of the other group, at an own cost. Reducing payoffs entails no material benefit for either the...

We investigate parochial altruism, the combination of in-group altruism and out-group hostility, in an experimental conflict game preceded by a prisoner’s dilemma. Our data are consistent with parochial altruism, but cannot be explained by in-group pro-sociality or out-group hostility alone.

We introduce two variants of the one-shot joy-of-destruction minigame (mini-JOD). Two players are endowed with the same amount of money. They simultaneously decide whether or not to reduce the payoff of the other player at an own cost. In one treatment there was a probability that Nature would...
