Public goods games in populations with fluctuating size.
Many mathematical frameworks of evolutionary game dynamics assume that the total population size is constant and that selection affects only the relative frequency of strategies. Here, we consider evolutionary game dynamics in an extended Wright-Fisher process with variable population size. In such a scenario, it is possible that the entire population becomes extinct. Survival of the population...
متن کاملImpact of critical mass on the evolution of cooperation in spatial public goods games.
We study the evolution of cooperation under the assumption that the collective benefits of group membership can only be harvested if the fraction of cooperators within the group, i.e., their critical mass, exceeds a threshold value. Considering structured populations, we show that a moderate fraction of cooperators can prevail even at very low multiplication factors if the critical mass is mini...
متن کاملFactor interaction dynamics in evolutionary public goods games with a critical mass
We study the evolution of cooperation in evolutionary public goods games on scale-free networks, reminiscent of social ties. Our assumption is that a critical mass of individuals is necessary as a precursor to collective action, in a manner reflective of tipping point phenomena. Investment heterogeneity in individual participants is allowed to arise due to varying interests, resources or other ...
متن کاملPublic Goods Games
Centralized sanctioning institutions are of utmost importance for overcoming free-riding tendencies and enforcing outcomes that maximize group welfare in social dilemma situations. However, little is known about how such institutions come into existence. In this paper we investigate, both theoretically and experimentally, the endogenous formation of institutions in a public goods game. Our theo...

*Correspondence: James A. R. Marshall, Department of Computer Science, Kroto Research Institute, University of Sheffield, Broad Lane, Sheffield S3 7HQ, UK e-mail: james.marshall@ sheffield.ac.uk Inclusive fitness theory has been described as being limited to certain special cases of social evolution. In particular some authors argue that the theory can only be applied to social interactions hav...
