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...

This paper investigates the effects of motivations on the perceived kindness of an action within the context of strong social indirect reci- procity. We test experimentally the hypothesis that, for a given dis- tributional outcome, an action is perceived by a third party to be less kind if it...

One of the key issues for understanding reciprocity is how agents evaluate the kindness of an action. In this paper we investigate experimentally the hypothesis that the motivation driving an action is relevant for its perceived kindness and, as a consequence, for reciprocal behavior. In...

We study the process by which subordinated regions of a country can obtain a more favourable political status. In our theoretical model a dominant and a dominated region first interact through a voting process that can lead to different degrees of autonomy. If this process fails then both...

This paper considers a duopoly price-choice game in which the unique Nash equilibrium is the Bertrand outcome. Price competition, however, is imperfect in the sense that the market share of the high-price firm is not zero. Economic intuition suggests that price levels should be positively...

This paper presents an experimental analysis of the role of out comes and intentions for fair behavior. We consider a symmetric version of the gift-exchange game in a 2x2 design with two treatment variables: intentionality (¯rst mover's choice is either intentional or randomly determined) and...

We study how conflict in a contest game is influenced by rival parties being groups and by group members being able to punish each other. Our main motivation stems from the analysis of socio-political conflict. The relevant theoretical prediction in our setting is that conflict expenditures are...
