We consider genotypic convergence of populations and show that under fixed fitness asexual and haploid sexual populations attain monomorphic convergence (even with linkage disequilibrium) to basins of attraction with locally exponential convergence rates; the same convergence obtains in single...

We model and experimentally evaluate the trade-off between innovation and imitation commonly faced by firms and individuals. Innovation involves searching for a high payoff opportunity, but paying a cost to do so. Imitation involves avoiding the search cost and copying the most successful payoff...

This paper develops an evolutionary approach to investigate (i) whether the observability of altruism or envy evolved in humans through a process of natural selection, (ii) what causes individuals to choose altruism or envy, and (iii) whether the survival of individuals coincides with the...

This paper examines evolutionary stability of preferences by employing deterministic replicator dynamics. The preferences of players are classified into three types: altruism, selfishness, and envy. In the stage game, players compete in pairs to maximize their subjective utilities, and, as a...

In many social situations, individuals endeavor to find the single best possible partner, but are constrained to evaluate the candidates in sequence. Examples include the search for mates, economic partnerships, or any other long-term ties where the choice to interact involves two parties....
