Personalized and continuing relationships play a central role in any society. Economists have built upon the theories of repeated games and reputations to make important advances in understanding such relationships. Repeated Games and Reputations begins with a careful development of the fundamental concepts in these theories, including the notions of a repeated game, strategy, and equilibrium. Mailath and Samuelson then present the classic folk theorem and reputation results for games of perfect and imperfect public monitoring, with the benefit of the modern analytical tools of decomposability and self-generation. They also present more recent developments, including results beyond folk theorems and recent work in games of private monitoring and alternative approaches to reputations. Repeated Games and Reputations synthesizes and unifies the vast body of work in this area, bringing the reader to the research frontier. Detailed arguments and proofs are given throughout, interwoven with examples, discussions of how the theory is to be used in the study of relationships, and economic applications. The book will be useful to those doing basic research in the theory of repeated games and reputations as well as those using these tools in more applied research.

For games of public reputation with uncertainty over types and imperfect public monitoring, Cripps, Mailath, and Samuelson (2004) showed that an informed player facing short-lived uninformed opponents cannot maintain a permanent reputation for playing a strategy that is not part of an equilibrium of the game without uncertainty over types. This paper extends that result to games in which the uninformed player is long-lived and has private beliefs, so that the informed player's reputation is private. We also show that the rate at which reputations disappear is uniform across equilibria and that reputations disappear in sufficiently long discounted finitely-repeated games.

This dissertation consists of three essays on reputation and repeated games. Reputation models typically assume players have full memory of past events, yet in many applications this assumption does not hold. In the first chapter, I explore two different relaxations of the assumption that history is perfectly observed in the context of Ely and Välimäki's (2003) mechanic game, where reputation (with full history observation) is clearly bad for all players. First I consider "limited history," where short-run players see only the most recent T periods. For large T, the full history equilibrium behavior always holds due to an "echo" effect (for high discount factors); for small T, the repeated static equilibrium exists. Second I consider "fading history," where short-run players randomly sample past periods with probabilities that "fade" toward zero for older periods. When fading is faster than a fairly lax threshold, the long-run player always acts myopically, a result that holds more generally for reputation games where the long-run player has a strictly dominant stage game action. This finding suggests that reputational incentives may be too weak to affect long-run player behavior in some realistic word-of-mouth environments. The second chapter develops general theoretical tools to study incomplete information games where players observe only finitely many recent periods. I derive a recursive characterization of the set of equilibrium payoffs, which allows analysis of both stationary and (previously unexplored) non-stationary equilibria. I also introduce "quasi-Markov perfection," an equilibrium refinement which is a necessary condition of any equilibrium that is "non-fragile" (purifiable), i.e., robust to small, additively separable and independent perturbations of payoffs. These tools are applied to two examples. The first is a product choice game with 1-period memory of the firm's actions, obtaining a complete characterization of the exact minimum and maximum purifiable equilibrium payoffs for almost all discount factors and prior beliefs on an "honest" Stackelberg commitment type, which shows that non-stationary equilibria expand the equilibrium set. The second is the same game with long memory: in all stationary and purifiable equilibria, the long-run player obtains exactly the Stackelberg payoff so long as the memory is longer than a threshold dependent on the prior. These results show that the presence of the honest type (even for arbitrarily small prior beliefs) qualitatively changes the equilibrium set for any fixed discount factor above a threshold independent of the prior, thereby not requiring extreme patience. The third chapter studies the question of why drug trafficking organizations inflict violence on each other, and why conflict breaks out under some government crackdowns and not others, in a repeated games context. Violence between Mexican drug cartels soared following the government's anti-cartel offensive starting in 2006, but not under previous crackdowns. I construct a theoretical explanation for these observations and previous empirical research. I develop a duopoly model where the firms have the capacity to make costly attacks on each other. The firms use the threat of violence to incentivize inter-cartel cooperation, and under imperfect monitoring, violence occurs on the equilibrium path of a high payoff equilibrium. When a "corrupt" government uses the threat of law enforcement as a punishment for uncooperative behavior, violence is not needed as frequently to achieve high payoffs. When government cracks down indiscriminately, the firms may return to frequent violence as a way of ensuring cooperation and high payoffs, even if the crackdown makes drug trafficking otherwise less profitable.

This book is an exploration of how knowledge about the reliability of information sources manifests itself in linguistic phenomena and use. It focuses on cooperation in language use and on how considerations of reliability influence what is done with the information acquired through language. E. McCready provides a detailed account of the phenomena of hedging and evidentiality and analyses them using tools from game theory, dynamic semantics, and formal epistemology. Hedging is argued to be a mechanism used by speakers to protect their reputations for cooperativity from damage inflicted by infelicitous discourse moves. The pragmatics of evidential use is also discussed in terms of the histories of interaction that influence reputation: the author argues that past experience with the evidence source indexed by the evidential determines how the process of adding information will proceed. The book makes many new connections between seemingly disparate aspects of linguistic meaning and practice. It will be of interest to specialists in semantics, pragmatics, and philosophy of language, as well as those in the fields of philosophy and cognitive science with an interest in language and epistemology.

Used to explain complicated economic behavior for decades, game theory is quickly becoming a tool of choice for those serious about optimizing next generation wireless systems. Illustrating how game theory can effectively address a wide range of issues that until now remained unresolved, Game Theory for Wireless Communications and Networking provides a systematic introduction to the application of this powerful and dynamic tool. This comprehensive technical guide explains game theory basics, architectures, protocols, security, models, open research issues, and cutting-edge advances and applications. It describes how to employ game theory in infrastructure-based wireless networks and multihop networks to reduce power consumption—while improving system capacity, decreasing packet loss, and enhancing network resilience. Providing for complete cross-referencing, the text is organized into four parts: Fundamentals—introduces the fundamental issues and solutions in applying different games in different wireless domains, including wireless sensor networks, vehicular networks, and OFDM-based wireless systems Power Control Games—considers issues and solutions in power control games Economic Approaches—reviews applications of different economic approaches, including bargaining and auction-based approaches Resource Management—explores how to use the game theoretic approach to address radio resource management issues The book explains how to apply the game theoretic model to address specific issues, including resource allocation, congestion control, attacks, routing, energy management, packet forwarding, and MAC. Facilitating quick and easy reference to related optimization and algorithm methodologies, it supplies you with the background and tools required to use game theory to drive the improvement and development of next generation wireless systems.
