We consider an election that is solely concerned with redistribution of income. It is well known that when voters are selfish, there is no political equilibrium. We consider the case where voters are modestly altruistic. We demonstrate that modest altruism results in a unique political...

A preference for negative reciprocity is an important part of the human emotional repertoire. We model its role in sustaining cooperative behavior but highlight an intrinsic free-rider problem: the fitness benefits of negative reciprocity are dispersed throughout the entire group, but the...

This paper introduces two ideas, emotional state dependent utility components (ESDUCs), and evolutionary perfect Bayesian equilibrium (EPBE). Using a simple extensive form game, we illustrate the efficiency-enhancing role of a powerful ESDUC, the vengeance motive. Incorporating behavioral noise...

This paper develops a nonparametric theory of preferences over one's own and others' monetary payoffs. We introduce more altruistic than (MAT), a partial ordering over preferences, and interpret it with known parametric models. We also introduce and illustrate more generous than (MGT),a partial...
