Why is it that well-intentioned actions can create persistent conflicts? While norms are widely regarded as a source for cooperation, this article proposes a novel theory in which the emergence of norms can be understood as a bargaining process in which normative conflicts explain the finally...

We provide a framework to decompose preferences into a notion of distributive justice and a selfishness part and to recover individual notions of distributive justice from data collected in appropriately designed experiments. "Dictator games" with varying transfer rates used in Andreoni and...

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...

We enrich the choice task of responders in ultimatum games by allowing them to independently decide whether to collect what is offered to them and whether to destroy what the proposer demanded. Such a multidimensional response format intends to cast further light on the motives guiding responder...

We report the results of a combination of a dictator experiment with either a "social planner" or a "veil of ignorance" experiment. The experimental design and the analysis of the data are based on the theoretical framework proposed in the companion paper by Becker, Häger, and Heufer (BHH,...

Social lotteries are lotteries that are played along with someone else. The experimental literature indicates that risk attitudes depend on how one's situation in the safe alternative compares to that of a peer. Evaluation of the risky alternative also depends on whether the lottery gives equal...

How malleable are people´s fairness ideals? Although fairness is an oft-invoked concept in allocation situations, it is still unclear whether and to what extent people´s allocations reflect their fairness ideals. We investigate in a laboratory experiment whether people´s fairness ideals vary...

Do individuals prefer to compete fairly, or unfairly with an opponent? We study individuals who can choose how to compete for one ex-post nonzero payoff. They can either nudge themselves into a fair set of rules where they have the same information and actions as their opponent, or into unfair...

We empirically analyze the relationship between income inequality and individual preferences for public redistribution, focusing on intra-household income inequality between spouses. Using data from the German Socio-Economic Panel, we find that both one's own earned income and earned...

One's willingness to accept an outcome or even to correct it depends on whether or not the underlying procedure is deemed legitimate. We manipulate the role allocation procedure in the dictator game to illustrate that this belief is not independent of the outcome and is self-serving in its...
