Engelmann and Strobel (AER 2004) claim that a combination of efficiency seeking and minmax preferences dominates inequity aversion in simple dictator games. This result relies on a strong subject pool effect. The participants of their experiments were undergraduate students of economics and...

This paper analyzes responsibility attributions for outcomes of collective decision making processes. In particular, we ask if decision makers are blamed for being pivotal if they implement an unpopular outcome in a sequential voting process. We conduct an experimental voting game in which...

We report on an experiment designed to explore whether a written expression of disapproval affects future levels of cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment, either gives or does not give the recipient the...

This study attempts to combine two traditional fields in microeconomics: individual decision making under risk and decision making in an interpersonal context. The influence of social comparison on risky choices is explored in an experiment in which participants make a series of choices between...

While inequality in resource endowments has been shown to affect cooperation levels in groups, much of this evidence comes from studies of within-group inequality. In an online public goods experiment, we instead examine the effects of payoff-irrelevant inequality in resources between groups on...

Policy interventions are generally evaluated for their direct effectiveness. Little is known about their ability to persist over time and spill across contexts. These latter aspects can reinforce or offset the direct impacts depending on the policy instrument choice. Through an online experiment...

Do groups exhibit more or less inequality aversion than individuals? Although the previous literature has shown that in many environments individuals in groups make more selfish decisions than when deciding in isolation, we find that individuals express more inequality aversion when making...

In reciprocal interactions, both genuine kindness and self-interested material gain may motivate socially beneficial actions. The paper presents results from two experiments that distinguish the role of perceived motives in reciprocal decision making from the role of outcomes or perceived...

This paper presents a laboratory experiment that studies the effects of costly monitoring and heterogeneous social identities on an equity principle of reward allocation. In particular, the investigation is based on a two-stage mechanism where a production phase is followed by a distribution...

Are cooperative decisions typically made more quickly or slowly than non-cooperative decisions? While this question has attracted considerable attention in recent years, most research has focused on one-shot interactions. Yet it is repeated interactions that characterize most important...
