Other-regarding preferences in a non-human primate: common marmosets provision food altruistically.
Human cooperation is unparalleled in the animal world and rests on an altruistic concern for the welfare of genetically unrelated strangers. The evolutionary roots of human altruism, however, remain poorly understood. Recent evidence suggests a discontinuity between humans and other primates because individual chimpanzees do not spontaneously provide food to other group members, indicating a la...
متن کاملOther-Regarding Preferences and Consequentialism
This dissertation addresses a basic difficulty in accommodating other-regarding preferences within existing models of decision making. Decision makers with such preferences may violate the property of stochastic dominance that is shared by both expected utility and almost any model of non-expected utility. At its core, stochastic dominance requires a decision maker's behavior to conform to a ba...
متن کاملRank-Dependent Other-Regarding Preferences
The comonotonic additivity axiom has been applied successfully in behavior under risk and uncertainty, and in an other-regarding setting it suggests that preferences over two allocations are independent of the payoffs of unaffected players as long as both allocations generate the same rank order of payoffs. If other-regarding preferences satisfy comonotonic additivity and violate standard addit...
متن کاملFood avoidance learning in squirrel monkeys and common marmosets.
Using a conditioned food avoidance learning paradigm, six squirrel monkeys (Saimiri sciureus) and six common marmosets (Callithrix jacchus) were tested for their ability to (1) reliably form associations between visual or olfactory cues of a potential food and its palatability and (2) remember such associations over prolonged periods of time. We found (1) that at the group level both species sh...
متن کاملFair Social Orderings with Other-Regarding Preferences
We study the fair division of a one dimensional good when individuals have other-regarding preferences. Assuming no legitimate claims, we ask how society should rank all possible allocations for every profile of ordinal preferences. In both a model of average and positional externalities, we characterize a class of social preferences which satisfy appealing efficiency and equity properties. The...
