Most political and economic theorists point to moral hazard in teams as the main obstacle to lobbies' collective action. In this paper, we address this important issue with a coalition-formation game. In the process of doing so, we characterize equilibrium lobby structures both in the absence...

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 socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and...

We replicate the experiment introduced by Fischbacher, Gächter and Fehr (2001) measuring the level of conditional cooperation in a one-shot public goods game. We collected data of 160 students from four different locations in urban and rural Russia. Like Fischbacher et al. we can classify about...

Field evidence suggests that people belonging to the same group often behave similarly, i.e., behavior exhibits social interaction effects. We conduct a laboratory experiment that avoids the identification problem present in the field and allows us to study the behavioral logic of social...

We provide a direct test of the role of social preferences in voluntary cooperation. We elicit individuals’ cooperation preference in one experiment and make a point prediction about the contribution to a repeated public good. This allows for a novel test as to whether there are "types" of...

We use an experimental lottery choice task and public goods game to examine if responsibility for the financial welfare of others affects decisionmaking behaviour in two different types of decision environments. We find no evidence that responsibility affects individual risk preferences....

Field evidence suggests that people belonging to the same group often behave similarly, i.e., behavior exhibits social interaction effects. We conduct a laboratory experiment that avoids the identification problem present in the field and allows us to study the behavioral logic of social...

We use a limited information environment to mimic the state of confusion in an experimental, repeated public goods game. The results show that reinforcement learning leads to dynamics similar to those observed in standard public goods games. However, closer inspection shows that individual decay...

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 socio-political conflict. The theoretical prediction is that conflict expenditures are independent of group size and...

We compare the strategy method and the direct response method in public good experiments in a within-subject design. This comparison is interesting because the strategy method is frequently used to investigate preference heterogeneity. We find that people identified by the strategy method as...
