Trust-repayment behavior is crucial to establish and maintain cooperative links between different (even genetically unrelated) individuals. However, neither the exact nature of this behavior considered mainly as reciprocity, ...

This paper employs an indirect approach to formally examine the evolutionary stability of interdependent preferences when players randomly engage in pairwise interactions. Following the model specification for altruism and ...

In this work we review converging evidence from several lines of research which suggests that altruism in humans can be intrinsically rewarding. Various investigations illustrate how human altruism can have beneficial ...

Altruism (a costly action that benefits others) and reciprocity (the repayment of acts in kind) differ in that the former expresses preferences about the outcome of a social interaction, whereas the latter requires, in ...
