Florian Herold: Carrot or Stick? Group Selection and the Evolution of Reciprocal Preferences
نویسنده
چکیده
This paper studies the evolution of both characteristics of reciprocity the willingness to reward friendly behavior and the willingness to punish hostile behavior. Firstly, preferences for rewarding as well as preferences for punishing can survive evolution provided individuals interact within separated groups. This holds even with randomly formed groups and even when individual preferences are unobservable. Secondly, preferences for rewarding survive only in coexistence with self-interested preferences. But preferences for punishing tend either to vanish or to dominate the population entirely. Finally, the evolution of preferences for rewarding and the evolution of preferences for punishing influence each other decisively. The existence of rewarders enhances the evolutionary success of punishers, but punishers crowd out rewarders. JEL-Classification: C72, D63, D64, D83

متن کاملDiscriminative host sanction together with relatedness promote the cooperation in fig/fig wasp mutualism.
Sanctioning or punishing is regarded as one of the most important dynamics in the evolution of cooperation. However, it has not been empirically examined yet whether or not such enforcement selection by sanctioning or punishing and classical theories like kin or reciprocity selection are separate mechanisms contributing to the evolution of cooperation. In addition, it remains largely unclear wh...
متن کامل1 The Evolution of Obedience Norms in the Repeated Carrot - and - the - Stick
Reciprocity norm in the U.S. Congress and state assemblies has been studied extensively. By contrast, obedience norms frequently observed in many legislative bodies outside the United States have received relatively little attention. We seek to provide an evolutionary account of obedience norms. Drawing on a detailed observation of the legislative game in the Korean National Assembly, we model ...
