We study the relevance of fairness norms in an experimental scenario in which hired and rented hands are co-employed and stochastic influences and multiple reference points for fairness further increase complexity. Co-employment of hired and rented hands is an example out of a broader class of...

Although one may hope to achieve equality of stated profits withoutenforcing it, one may not trust in such voluntary equality seeking andrather try to impose rules (of bidding) guaranteeing it.[...]

Different evaluators typically disagree how to rank different candidates since theycare more or less for the various qualities of the candidates. It is assumed that allevaluators submit vector bids assigning a monetary bid for each possible rank order.The rules must specify for all possible...

Retributive responses do play a role in human behavior. Whether they are primarily triggered by supposed intentions or by observed consequences of actions is an important question. It can be addressed by experimental studies of retributive responses in situations in which the individual actor...

Fairness is a strong concern as shown by dictator and ultimatum experiments. Efficiency, measured by the sum of individual payoffs, is a potentially competing concern in games such as the prisoners' dilemma. In our experiment participants can increase efficiency by gift giving. In the one-sided...
