An important problem in theoretical biology is to explain how altruism can have positive selection value. We model socialization as a costly public good that raises altruism and we study evolution equations for altruistic preferences. Stable cultural (social) equilibria exist in which...

We study economic natural selection in classical oligopoly settings. When underlying pure strategies consist of a finite number of prices, convex monotonic dynamics always converge under a weak condition to the smallest price in the support of the initial state that exceeds marginal cost. When...
