Available in PDF, EPUB and Kindle. Book excerpt: We study games with strategic complementarities, arbitrary numbers of players and actions, and slightly noisy payoff signals. We prove limit uniqueness: as the signal noise vanishes, the game has a unique strategy profile that survives iterative dominance. This generalizes a result of Carlsson and van Damme (1993) for two player, two action games. Te surviving profile, however, may depend on fine details of the structure of the noise. We provide sufficient conditions on payoffs for there to be noise-independent selection.

Available in PDF, EPUB and Kindle. Book excerpt: This book develops a general solution concept for strategic games which resolves strategic uncertainty completely. The concept is described by a mathematically formulated solution procedure and illustrated by applying it to many interesting examples. A long nontechnical introduction tries to survey and to discuss the more technical parts of the book. The book and especially the introduction provide firm and consistent guidance for scholars of game theory. There are many open problems which could inspire further research efforts.

Book excerpt: Global games are games of incomplete information whose type space is determined by the players each observing a noisy signal of the underlying state. With strategic complementarities, global games often have a unique, dominance solvable equilibrium, allowing analysis of a number of economic models of coordination failure. For symmetric binary action global games, equilibrium strategies in the limit (as noise becomes negligible) are simple to characterize in terms of 'diffuse' beliefs over the actions of others. We describe a number of economic applications that fall in this category. We also explore the distinctive roles of public and private information in this setting, review results for general global games, discuss the relationship between global games and a literature on higher order beliefs in game theory and describe the relationship to local interaction games and dynamic games with payoff shocks.
Download or read book Evolutionary Games and Equilibrium Selection written by Larry Samuelson and published by MIT Press. This book was released on 1997 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author examines the interplay between evolutionary game theory and the equilibrium selection problem in noncooperative games. Evolutionary game theory is one of the most active and rapidly growing areas of research in economics. Unlike traditional game theory models, which assume that all players are fully rational and have complete knowledge of details of the game, evolutionary models assume that people choose their strategies through a trial-and-error learning process in which they gradually discover that some strategies work better than others. In games that are repeated many times, low-payoff strategies tend to be weeded out, and an equilibrium may emerge. Larry Samuelson has been one of the main contributors to the evolutionary game theory literature. In Evolutionary Games and Equilibrium Selection, he examines the interplay between evolutionary game theory and the equilibrium selection problem in noncooperative games. After providing an overview of the basic issues of game theory and a presentation of the basic models, the book addresses evolutionary stability, the dynamics of sample paths, the ultimatum game, drift, noise, backward and forward induction, and strict Nash equilibria.

Book excerpt: This Palgrave Pivot examines monotone games and studies incentives and outcomes when there are multiple players, and how the decision of each player affects the well-being of others in particular ways. Games with strategic complements exhibit codirectional incentives, or incentives for each player to move in the same direction as other players. Games with strategic substitutes exhibit contradirectional incentives, or incentives for each player to move in the direction opposite to other players. Monotone games include both types of players: some players have incentives to move in the same direction as other players and some players have incentives to move in the direction opposite to other players. This book develops the theory of monotone games in a new and unified manner and presents many applications. Incentives and outcomes studied in monotone games occur in a variety of disciplines, including biology, business, computer science, economics, mathematics, medicine, philosophy, political science, and psychology, among others. The book identifies unifying threads across different cases, showing how newer results are similar to or different from previous results, and how readers may better understand them under the umbrella of monotone games.

Available in PDF, EPUB and Kindle. Book excerpt: We study large games played by heterogeneous agents whose payoffs depend on the aggregate action and provide novel equilibrium selection and comparative statics results. We prove the equivalence between the global games selection and potential maximization in games with strategic complementarities, and characterize the selected equilibrium as the solution to maximizing the ex-ante expected payoffs of a player with pessimistic beliefs. To obtain our results we uncover two key properties. First, we show that potential games exhibit quasilinear payoffs, which include as examples Cournot competition, public goods and externalities, search models and coordination games. Second, we show that beliefs in the global game satisfy a generalized Laplacian property, which links average beliefs about the aggregate action to the uniform distribution. Our comparative statics results rely on average rather than pointwise conditions on payoffs and can be used to analyze both parameter changes and the impact of heterogeneity.

Available in PDF, EPUB and Kindle. Book excerpt: Chapter 1 analyzes how pre-play communication and evolution together do or do not lead to socially efficient equilibria in 2 x 2 symmetric coordination games. In our evolutionary dynamics, there are committed players who can choose only one particular action of the base game, as well as those players who can choose message contingent actions, and the evolution in the choice of message is faster than the evolution in actions. We show the Pareto efficient equilibria are selected if and only if the base game satisfies the self-signalling condition, which means that a player has an incentive to convince the opponent that he is going to play the Pareto efficient equilibrium strategy if and only if he is actually planning to play that strategy. Chapter 2 analyzes a stochastic evolutionary dynamics of Kandori-Mailath-Rob (1993) in Spence's job-market signaling model. In contrast to Nldeke and Samuelson's (1997) analysis which showed the Riley equilibrium is selected only if it is undefeated, we show that the Riley equilibrium is always selected. The key which makes this difference is how mutations affect players' behavior. While Noldeke and Samuelson allow a single mutation to change players' actions drastically, we consider a model where players change behavior only slightly if the number of mutations is small. Chapter 3 analyzes pure strategy Markov perfect equilibria in two player asynchronous choice repeated games where the stage game is a 2 x 2 game. We show that Markov perfect equilibrium leads players to behave differently from the static Nash equilibrium in some environments, while in other environment it gives equilibrium selection results.

Download or read book Game Equilibrium Models I written by Reinhard Selten and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are two main approaches towards the phenotypic analysis of frequency dependent natural selection. First, there is the approach of evolutionary game theory, which was introduced in 1973 by John Maynard Smith and George R. Price. In this theory, the dynamical process of natural selection is not modeled explicitly. Instead, the selective forces acting within a population are represented by a fitness function, which is then analysed according to the concept of an evolutionarily stable strategy or ESS. Later on, the static approach of evolutionary game theory has been complemented by a dynamic stability analysis of the replicator equations. Introduced by Peter D. Taylor and Leo B. Jonker in 1978, these equations specify a class of dynamical systems, which provide a simple dynamic description of a selection process. Usually, the investigation of the replicator dynamics centers around a stability analysis of their stationary solutions. Although evolutionary stability and dynamic stability both intend to characterize the long-term outcome of frequency dependent selection, these concepts differ considerably in the 'philosophies' on which they are based. It is therefore not too surprising that they often lead to quite different evolutionary predictions (see, e. g. , Weissing 1983). The present paper intends to illustrate the incongruities between the two approaches towards a phenotypic theory of natural selection. A detailed game theoretical and dynamical analysis is given for a generic class of evolutionary normal form games.
