Group selection models combine selection pressure at the individual level with selection pressure at the group level (Sober and Wilson, 1998; Traulsen and Nowak, 2006; Wilson and Wilson, 2007; Boyd and Richerson, 2009; Simon, 2010; Simon et al., 2013; Luo, 2014; van Veelen et al., 2014; Luo and Mattingly, 2017). Cooperation...

Alger and Weibull (2013) present a model for the evolution of preferences under incomplete information and assortative matching. Their main result is that Homo Moralis – who maximizes a convex combination of her narrow self-interest and “the right thing to do” – is evolutionarily stable,...

Most of the literature on the evolution of human pro-sociality looks at reasons why evolution made us not play the Nash equilibrium in prisoners’ dilemmas or public goods games. We suggest that in order to understand human morality, and human prosocial behaviour, we should look at reasons why...

Rand et al. (2013) present a finite population model to explain the evolution of fair behaviour in the ultimatum game. They find that mutation and selection can balance at population states that resemble human behaviour, in that responders on average evolve sizable thresholds for rejection, and...

This paper reviews and addresses a variety of issues relating to inclusive fitness. The main question is: are there limits to the generality of inclusive fitness, and if so, what are the perimeters of the domain within which inclusive fitness works? This question is addressed using two well...

Evolutionary explanations of anger as a commitment device hinge on two key assumptions. The first is that it is observable ex-ante whether someone will get angry when feeling badly treated. The second is that anger is associated with destructive behavior. We test the validity of these...

The question is whether or not there is a generally meaningful way to compute price indices. I explore the duality between price and quantity indices, and present an impossibility result that is analogous to the one for quantity indices.

Games that have no evolutionarily stable strategy may very well have neutrally stable ones. (Neutrally stable strategies are also known as weakly evolutionarily stable strategies.) Such neutrally, but not evolutionarily stable strategies can however still be relatively stable or unstable,...
