We study fairness and reciprocity in a Hawk-Dove game. This alllows us to testvarious models in one framework. We observe a large extent of selfish and rationalbehavior. Our results are inconsistent with leading models in this field.

Numerous gift exchange experiments have found a positive relationship between employers' wage offers and workers' effort levels. In (almost) all these experiments the employer both owns and controls the firm. Yet in reality many firms are characterized by the separation of ownership and control....

Incentive instruments like asset ownership and performance pay often have to strike a balance between the productive incentives and the rent-seeking incentives they provide. Standard theory predicts that a given instrument becomes less attractive when the effectiveness of rent-seeking activities...

One of the main findings of a large body of gift exchange experiments is that in an incomplete contracts environment workers on average do not shirk and usually provide more than the minimum enforceable effort level. In general, 40 to 60 percent of the workers reward higher wages with higher...

This paper investigates an implication of the self-serving bias for reciprocalresponses. It is hypothesized that negative intentionality matters more thanpositive intentionality for reciprocating individuals with a self-servingattributional style. Experimental evidence obtained in the hot...
