We compare experimentally the revealed distributional preferences of individuals and teams in allocation tasks. We find that teams are significantly more benevolent than individuals in the domain of disadvantageous inequality while the benevolence in the domain of advantageous inequality is...

This paper proposes a geometric delineation of distributional preference types and a non-parametric approach for their identification in a two-person context. It starts with a small set of assumptions on preferences and shows that this set (i) naturally results in a taxonomy of distributional...

We study optimal direct mechanisms for a credence goods expert who can be altruistic or spiteful. The expert has private information about her distributional preferences and possibly also about her customer's needs. We introduce a method that allows the customer to offer separate contracts to...

In an experiment on a subjective claims problem we compare three unanimity bargaining procedures - the Demand, the Offer and the Exit variant - in terms of fairness and efficiency. To assess the fairness of the allocations obtained by these procedures, we evaluate them from a partial point of...

In a subjective claims problem several agents have contributed to the production of a cake which is to be divided among them. Since contributions are difficult to compare and the production function is nonlinear, agents'subjective evaluations of claims are likely to be conflicting. In a...

We study credence goods markets where an expert not only cares for her own monetary payoff, but also for the monetary payoff of her customer. We show how an expert with heterogeneous distributional preferences responds to monetary incentives in the absence of institutions, under liability and/or...

Extensive evidence from laboratory experiments indicates that many individuals are willing to use costly punishment to enforce social norms, even in one-shot interactions. However, there appears to be little evidence in the literature of such behavior in the field. We study the propensity to...

We study in a sample of 1,070 primary school children, aged seven to eleven years, how altruism in a donation experiment is related to children’s risk attitudes and intertemporal choices. Examining such a relationship is motivated by theories of reciprocal altruism that provide a cornerstone...

This paper reports the results of experiments designed to isolate the impact of various combinations of the following motives on trustworthiness: (i) unconditional other-regarding preferences - like altruism, inequality aversion, quasi-maximin, etc.; (ii) deal-responsiveness - reacting to...
