Perfect competition provides the model of a frictionless economy, in which price-setting economic agents behave independently of each other, abandoning to the market the coordination of their individual decisions. The implications of this model are extensively presented in the traditional price theory textbooks. Imperfect competition is the paradigm that develops as soon as economic agents interact in a conscious manner, which is the rule when competition takes place amongst a restricted number of agents. In this system, agents act strategically, taking into account the impact of their decisions on competitors' behaviour and on the price mechanism. Such situations commonly arise when firms differentiate their products, erect strategic entry barriers, or exploit the imperfect information of their customers about the price or characteristics of their product. This book explores the theoretical richness of these economic contexts, using some basic tools of game theory. Designed as an ancillary text for graduate students, it not only summarizes the historic contributions made by economic theorists such as Cournot and Edgeworth, but also makes accessible many of the most recent developments in the same field.

Strategic interaction occurs whenever it depends on others what one finally obtains: on markets, in firms, in politics etc. Game theorists analyse such interaction normatively, using numerous different methods. The rationalistic approach assumes perfect rationality whereas behavioral theories take into account cognitive limitations of human decision makers. In the animal kingdom one usually refers to evolutionary forces when explaining social interaction. The volume contains innovative contributions, surveys of previous work and two interviews which shed new light on these important topics of the research agenda. The contributions come from highly regarded researchers from all over the world who like to express in this way their intellectual inspiration by the Nobel-laureate Reinhard Selten.

The two essays in this classic work by sociologist Erving Goffman deal with the calculative, gamelike aspects of human interaction. Goffman examines the strategy of words and deeds; he uses the term "strategic interaction" to describe gamelike events in which an individual's situation is fully dependent on the move of one's opponent and in which both players know this and have the wit to use this awareness for advantage. Goffman aims to show that strategic interaction can be isolated analytically from the general study of communication and face-to-face interaction. The first essay addresses expression games, in which a participant spars to discover the value of information given openly or unwittingly by another. The author uses vivid examples from espionage literature and high-level political intrigue to show how people mislead one another in the information game. Both observer and observed create evidence that is false and uncover evidence that is real. In "Strategic Interaction," the book's second essay, action is the central concern, and expression games are secondary. Goffman makes clear that often, when it seems that an opponent sets off a course of action through verbal communication, he really has a finger on your trigger, your chips on the table, or your check in his bank. Communication may reinforce conduct, but in the end, action speaks louder. Those who gamble with their wits, and those who study those who do, will find this analysis important and stimulating.

This book covers a large spectrum of cutting-edge game theory applications in management science in which Professor Georges Zaccour has made significant contributions. The book consists of 21 chapters and highlights the latest treatments of game theory in various areas, including marketing, supply chains, energy and environmental management, and cyber defense. With this book, former Ph.D. students and successful research collaborators of Professor Zaccour wish to honor his many scientific achievements.

"This book explores theories, approaches, methods, and tools on the use of interactive communication systems and technologies in interdisciplinary and multidisciplinary areas"--

Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.

Game theory, the formalized study of strategy, began in the 1940s by asking how emotionless geniuses should play games, but ignored until recently how average people with emotions and limited foresight actually play games. This book marks the first substantial and authoritative effort to close this gap. Colin Camerer, one of the field's leading figures, uses psychological principles and hundreds of experiments to develop mathematical theories of reciprocity, limited strategizing, and learning, which help predict what real people and companies do in strategic situations. Unifying a wealth of information from ongoing studies in strategic behavior, he takes the experimental science of behavioral economics a major step forward. He does so in lucid, friendly prose. Behavioral game theory has three ingredients that come clearly into focus in this book: mathematical theories of how moral obligation and vengeance affect the way people bargain and trust each other; a theory of how limits in the brain constrain the number of steps of "I think he thinks . . ." reasoning people naturally do; and a theory of how people learn from experience to make better strategic decisions. Strategic interactions that can be explained by behavioral game theory include bargaining, games of bluffing as in sports and poker, strikes, how conventions help coordinate a joint activity, price competition and patent races, and building up reputations for trustworthiness or ruthlessness in business or life. While there are many books on standard game theory that address the way ideally rational actors operate, Behavioral Game Theory stands alone in blending experimental evidence and psychology in a mathematical theory of normal strategic behavior. It is must reading for anyone who seeks a more complete understanding of strategic thinking, from professional economists to scholars and students of economics, management studies, psychology, political science, anthropology, and biology.
