Cooperation and Local Interactions in the Prisoners ’ Dilemma Game
* I want to thank Hans Haller and Mark Stegeman for their valuable suggestions and support. The paper benefited from the comments of participants in the 1997 SITE Summer Workshop. Abstract We consider a population of players playing a Prisoners' Dilemma Game in a local interaction setting, using a formalism of automata networks. Sufficient conditions for existence of an equilibrium where cooper...
متن کاملScale-invariant behavior in a spatial game of prisoners' dilemma.
A spatially extended version of the game of prisoner's dilemma, originally proposed by Nowak and May, is modified to include stochastic updating and found to exhibit scale-invariant behavior. Two critical regimes with different scaling behaviors are found; the corresponding exponents have been determined numerically. Spatially, the critical states are characterized by the existence of delicatel...
متن کاملThe Prisoners' Dilemma Revisited
Cooperation has always been recognised as a fundamental ingredient in the creation of societies and the generation of wealth. As a concept, it has been studied for many years. Yet, in practice, its emergence and persistence are less understood. In the following a game theoretic approach to the study of cooperation based on the Prisoners' Dilemma is reviewed. Using a Genetic Algorithm, strategie...
متن کاملPrisoners' other Dilemma
We ...nd that cooperation as equilibrium of the in...nitely repeated discounted Prisoner’s Dilemma is often not plausible: For a signi...cant subset of the payo¤discount factor parameter space, all co-operation equilibria are strictly risk dominated (in the sense of Harsanyi and Selten, 1988) by defection. We derive an easy-to-calculate critical level for the discount factor ±¤ below which this...
متن کاملFoundations for Cooperation in the Prisoners ’ Dilemma
We provide axiomatic foundations for a simple model of play in prisoners’ dilemma games. The model accommodates cooperation and suggests that players behave as if their expectations about their opponents’ behavior vary with their own choice. We refer to this nonstandard updating as magical thinking. The degree to which players exhibit magical thinking may be heterogeneous in the population and ...
