20.500.12556/DKUM-66559 Probabilistic sharing solves the problem of costly punishment Cooperators that refuse to participate in sanctioning defectors create the secondorder free-rider problem. Such cooperators will not be punished because they contribute to the public good, but they also eschew the costs associated with punishing defectors. Altruistic punishers - those that cooperate and punish - are at a disadvantage, and it is puzzling how such behaviour has evolved. We show that sharing the responsibility to sanction defectors rather than relying on certain individuals to do so permanently can solve the problem of costly punishment. Inspired by the fact that humans have strong but also emotional tendencies for fair play, we consider probabilistic sanctioning as the simplest way of distributing the duty. In well-mixed populations the public goods game is transformed into a coordination game with full cooperation and defection as the two stable equilibria, while in structured populations pattern formation supports additional counterintuitive solutions that are reminiscent of Parrondoʼs paradox. social dynamics networks punishment public goods econophysics socialna dinamika mreže kazen javne dobrine ekonofizika true true true Angleški jezik Slovenski jezik Članek v reviji 2017-07-03 10:02:31 2017-07-03 10:03:22 2024-05-27 14:45:50 2019-07-11 15:51:29 2014 0 0 str. 1-15 Letn. 16 2014 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1367-2630 53 21135621 20806152 10.1088/1367-2630/16/8/083016 1367-2630 URN:SI:UM:DK:FL3GSNI4 New_Journal_of_Physics_2014_Chen,_Szolnoki,_Perc_Probabilistic_sharing_solves_the_problem_of_costly_punishment.pdf New_Journal_of_Physics_2014_Chen,_Szolnoki,_Perc_Probabilistic_sharing_solves_the_problem_of_costly_punishment.pdf 1 89A87294E70C2748A57CDDD38B3A12CA 17f3ade7e8ef75e5da0f32edcbc6b70e813c4dfaa592f150cd8a4c41dfc4446f 558e34bf-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113455 http://stacks.iop.org/1367-2630/16/i=8/a=083016?key=crossref.386c85aae3cd7994fe38ee525f977410 1 https://dk.um.si/Dokument.php?lang=slv&id=113454 Fakulteta za naravoslovje in matematiko 0 0 0
