What preferences will prevail in a society of rational individuals when preference evolution is
driven by the resulting payoffs? We show that when individuals' preferences are their private …

What kind of preferences should one expect evolution to favor? We propose a definition of
evolutionary stability of preferences in interactions in groups of arbitrary finite size. Groups …

According to Hamilton's (1964a, b) rule, a costly action will be undertaken if its fitness cost to
the actor falls short of the discounted benefit to the recipient, where the discount factor is …

What can evolutionary biology tell us about male-female differences in preferences
concerning family matters? Might mothers be more solicitous toward offspring than fathers …

This paper investigates the emergence of cooperation in a heterogeneous population that is
divided into two cultural groups. Agents are randomly matched in pairs to engage in a …

We study evolution of preferences in large population aggregative games. In such games,
all agents in society interact with each other. The material payoff or fitness of agents is …

This paper discusses alternative measures of assortative matching and relates them to
Sewall Wright's F-statistic. It also explores applications of measures of assortativity to …

This paper argues that political institutions play an important role in influencing the evolution
of character traits. We consider a population with two groups each with different character …

We model the evolution of preferences guiding behavior in pairwise interactions in group-
structured populations. The model uses long-term evolution theory to examine different …

We consider a population of agents whose preference types are unobservable but
imperfectly correlated with certain observable labels such as customs, languages, and …
