Kea show no evidence of inequity aversion
It has been suggested that inequity aversion is a mechanism that evolved in humans to maximize the pay-offs from engaging in cooperative tasks and to foster long-term cooperative relationships between unrelated individuals. In support of this, evidence of inequity aversion in nonhuman animals has typically been found in species that, like humans, live in complex social groups and demonstrate co...
متن کاملInequity aversion is observed in common marmosets but not in marmoset models of autism induced by prenatal exposure to valproic acid
Humans and various nonhuman primates respond negatively to inequity not in their favor (i.e., inequity aversion), when inequity between two individuals is introduced. Common marmosets, a highly prosocial species, further discriminated between human actors who reciprocated in social exchanges, and those who did not. Conversely, marmoset models of autism, induced via prenatal exposure to valproic...
متن کاملInequity aversion strategies between marmosets are influenced by partner familiarity and sex but not oxytocin.
Cooperation among individuals depends, in large part, on a sense of fairness. Many cooperating non-human primates (NHPs) show inequity aversion, (i.e., negative responses to unequal outcomes), and these responses toward inequity likely evolved as a means to preserve the advantages of cooperative relationships. However, marmosets (Callithrix spp.) tend to show little or no inequity aversion, des...
متن کاملContracts and Inequity Aversion
Inequity aversion is a special form of other regarding preferences and captures many features of reciprocal behavior, an apparently robust pattern in human nature. Using this concept we analyze the Moral Hazard problem and derive several results which differ from conventional contract theory. Our three key insights are: First, inequity aversion plays a crucial role in the design of optimal cont...
متن کاملInequity Aversion Revisited
We provide the first systematic study of the robustness of parameter estimates for the Fehr-Schmidt (1999) model of inequity aversion with respect to (i) the occurrence of efficiency concerns; (ii) the scale of payoffs; and (iii) the game used (i.e., cross-game consistency). Moreover, we provide evidence of a bias in the estimates that occurs if one does not correct for strategic considerations...
