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...

We study an ultimatum experiment in which the responder does not know the offer when accepting or rejecting. Unconditional veto power leads to acceptances, although proposers are significantly greedier than in standard ultimatum games, and this is anticipated by responders.

What we now label as "fair behavior" often differs from philopsophical norions of the concept. Establishing a clear understanding of the empirical nature of fairness is important if we are to gauge teh impact fairness has on economic and political institutions.[...]

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...

Several current social utility models posit fairness as a motive for certain types of strategic behavior. The models differ sharply with respect to how fairness is measured. Distribution models measure fairness in terms of relative payoff comparisons. Reciprocal-kindness models measure fairness...
