We propose a mathematical model to analyze the evolution of canalization for a trait under stabilizing selection, where each individual in the population is randomly exposed to different environmental conditions, independently of its genotype. Without canalization, our trait (primary phenotype) is affected by both genetic variation and environmental(More)

We study two-sided markets with a …nite numbers of agents on each side, and with two-sided incomplete information. Agents are matched assortatively on the basis of costly signals. Asymmetries in signaling activity between the two sides of the market can be explained either by asymmetries in size or in heterogeneity. Our main results identify general(More)
The paper provides an explanation for altruistic behavior based on the matching and learning technology in the population. In a in®nite structured population, in which individuals meet and interact with their neighbors, individuals learn by imitating their more successful neighbors. We ask which strategies are robust against invasion of mutants: A strategy(More)
Long-term co-evolution of male's sexual extravagance and female's preference for it is studied. Fisher's "Sexy Son" principle is checked against Zahavi's Handicap Principle. It is shown that although both principles are equally likely to explain this sort of co-evolution in the short run, only the second one allows for a long-term evolutionarily stable(More)

Abstract We study two-sided markets with a …nite numbers of agents on each side, and with two-sided incomplete information. Agents are matched assortatively on the basis of costly signals. A main goal is to identify conditions under which the potential(More)
This paper analyzes some decision and belief paradoxes from a Bayesian viewpoint, focusing on Hempel's "paradox of confirmation" and Good's variation thereof. It is shown that a straightforward Bayesian analysis resolves the paradoxes discussed. These examples are used to support the view that the Bayesian paradigm is a very effective tool for providing a(More)
