We consider a dynamic process of collective choice under majority rule in which a status quo policy evolves. The analysis is based on stochastic evolutionary game theory. The Condorcet winner is uniquely a long-run equilibrium for all (super-)majority rules. When the Condorcet winner does not...

We examine preference evolution under different marriage market arrangements, when preferences are influenced by own choices and parents' preferences. The dynamical system exhibits pitchfork bifurcation as the degree of sorting varies: Multiple stable equilibria arise under sufficiently random...

We present a model that investigates preference evolution with endogenous matching. In the short run, individuals’ subjective preferences simultaneously determine who they are matched with and how they behave in the social interactions with their matched partners, which results in material...

Building on previous literature that examines the influence of intergenerational transmission in cultural evolution, we highlight the importance of the marriage market in the determination of cultural homogeneity (“melting pot”) versus heterogeneity (“diversity”). To do so, we...
