Via Freedom to Coercion: The Emergence of Costly Punishment
(American Association for the Advancement of Science, 2007)
In human societies, cooperative behavior in joint enterprises is often enforced through institutions that impose sanctions on defectors. Many experiments on so-called public goods games have shown that in the absence of ...
Direct Reciprocity on Graphs
(Elsevier, 2007)
Direct reciprocity is a mechanism for the evolution of cooperation based on the idea of repeated encounters between the same two individuals. Here we examine direct reciprocity in structured populations, where individuals ...
Stochastic Payoff Evaluation Increases the Temperature of Selection
(Elsevier, 2007)
We study stochastic evolutionary game dynamics in populations of finite size. Moreover, each individual has a randomly distributed number of interactions with other individuals. Therefore, the payoff of two individuals ...
The One-Third Law of Evolutionary Dynamics
(Elsevier, 2007)
Evolutionary game dynamics in finite populations provide a new framework for studying selection of traits with frequency-dependent fitness. Recently, a “one-third law” of evolutionary dynamics has been described, which ...
Pairwise Comparison and Selection Temperature in Evolutionary Game Dynamics
(Elsevier, 2007)
Recently, the frequency-dependent Moran process has been introduced in order to describe evolutionary game dynamics in finite populations. Here, an alternative to this process is investigated that is based on pairwise ...
