This applies = a =-=A. The first is kin selection theory, the second is evolutionary game theory, the third is gene–culture coevolutionary theory, and the fourth is cultural niche construction. Andreu Mas-Colell, Michael D. Whinston, Jerry R. Green, Microeconomic Theory. In these species, the non-mating males would seem to be excessbaggage carried around by the rest of the population, having no realuse. • Game solution is the best strategy • Social scientists require rational behavior, evolution requires natural selection • A pair of strategies which represent the best replies to each alternative is a Nash equilibrium. Game theory studies how this should be done, and it provides various solution concepts which prescribe how agents should act when the actions of other agents affect their utilities. Ideas such as dominance, backward induction, Nash equilibrium, evolutionary stability, commitment, credibility, asymmetric information, adverse selection, and signaling are discussed and applied to games played in class and to examples drawn from economics, politics, the movies, and elsewhere.

Mixed ESS mechanisms • Stable strategy set in which a single individual sometimes performs one strategy and sometimes another with probability p • Stable polymorphic state in which a fraction, p, of the population adopts one strategy while the remainder, 1-p, adopts the other. Other authors have used evolutionary game theory to explain behavior in the ultimatum game. What is game theory?

Dark males are territorial, only a few mate, while light males follow females. This book both summarizes the basic theory of evolutionary games and explains their developing applications, giving special attention to the 2-player, 2-strategy game. DOMINANT STRATEGY FOR AN N-PLAYER GAME: A feasible strategy for a player in an N-player game is said to be a dominant strategy for this player if it is this player’s best response to any feasible choice of strategies for the other players.
