Adaptive Topographies and Equilibrium Selection in an Evolutionary Game
It has long been known in the field of population genetics that adaptive topographies, in which population equilibria maximise mean population fitness for a trait regardless of its genetic bases, do not exist. Whether one chooses to model selection acting on a single locus or multiple loci does matter. In evolutionary game theory, analysis of a simple and general game involving distinct roles f...
متن کاملStochastic Evolutionary Game Dynamics: Foundations, Deterministic Approximation, and Equilibrium Selection
We present a general model of stochastic evolution in games played by large populations of anonymous agents. Agents receive opportunities to revise their strategies by way of independent Poisson processes. A revision protocol describes how the probabilities with which an agent chooses each of his strategies depend on his current payoff opportunities and the current behavior of the population. O...
متن کاملEquilibrium selection in a nonlinear duopoly game with adaptive expectations
We analyze a nonlinear discrete time Cournot duopoly game, where players have adaptive expectations. The evolution of expected outputs over time is generated by the iteration of a noninvertible two-dimensional map. The long-run behavior is characterized by multistability, that is, the presence of coexisting stable consistent beliefs, which correspond to Nash equilibria in the quantity space. He...
متن کاملA differential Game Approach to Evolutionary Equilibrium Selection
Whenever a strategic game has more than one equilibrium, the players face a problem: which equilibrium should they play? Departing from Nash’s solution of the bargaining problem, Harsanyi and Selten (1988) invented a sophisticated method to select a unique equilibrium for each finite strategic game. Since this pioneering work, many other alternative methods of equilibrium selection were develop...
متن کاملEvolutionary Drift and Equilibrium Selection
This paper develops an approach to equilibrium selection in game theory based on studying . the learning process through which equilibrium is achieved. The differential equations derived from models of interactive learning typically have stationary states that are not isolated. Instead, Nash equilibria that specify different out-of-equilibrium behaviour appear in connected components of station...
