Book Synopsis Collective Rationality by : Paul Weirich
Download or read book Collective Rationality written by Paul Weirich and published by Oxford University Press. This book was released on 2009-12-01 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groups of people perform acts that are subject to standards of rationality. A committee may sensibly award fellowships, or may irrationally award them in violation of its own policies. A theory of collective rationality defines collective acts that are evaluable for rationality and formulates principles for their evaluation. This book argues that a group's act is evaluable for rationality if it is the products of acts its members fully control. It also argues that such an act is collectively rational if the acts of the group's members are rational. Efficiency is a goal of collective rationality, but not a requirement, except in cases where conditions are ideal for joint action and agents have rationally prepared for joint action. The people engaged in a game of strategy form a group, and the combination of their acts yields a collective act. If their collective act is rational, it constitutes a solution to their game. A theory of collective rationality yields principles concerning solutions to games. One principle requires that a solution constitute an equilibrium among the incentives of the agents in the game. In a cooperative game some agents are coalitions of individuals, and it may be impossible for all agents to pursue all incentives. Because rationality is attainable, the appropriate equilibrium standard for cooperative games requires that agents pursue only incentives that provide sufficient reasons to act. The book's theory of collective rationality supports an attainable equilibrium-standard for solutions to cooperative games and shows that its realization follows from individuals' rational acts. By extending the theory of rationality to groups, this book reveals the characteristics that make an act evaluable for rationality and the way rationality's evaluation of an act responds to the type of control its agent exercises over the act. The book's theory of collective rationality contributes to philosophical projects such as contractarian ethics and to practical projects such as the design of social institutions.

It generates new equilibrium standards for solutions to cooperative games.
Book Synopsis Rational Behavior and Bargaining Equilibrium in Games and Social Situations by : John C. Harsanyi
Download or read book Rational Behavior and Bargaining Equilibrium in Games and Social Situations written by John C. Harsanyi and published by CUP Archive. This book was released on 1986 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a paperback edition of a major contribution to the field, first published in hard covers in 1977. The book outlines a general theory of rational behaviour consisting of individual decision theory, ethics, and game theory as its main branches. Decision theory deals with a rational pursuit of individual utility; ethics with a rational pursuit of the common interests of society; and game theory with an interaction of two or more rational individuals, each pursuing his own interests in a rational manner.

Book Synopsis Rationality in Economics: Alternative Perspectives by : Ken Dennis
Download or read book Rationality in Economics: Alternative Perspectives written by Ken Dennis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ideas linked to rational choice theory started to appear frequently in the economics literature in the 1960s and 1970s, but the attention given to rationality widened to include commentators presenting far-reaching appraisals and critiques. The literature grew to a steady flow and spanned diverse areas of thought including socialist and `rational-choice Marxist' assessments, and other approaches including institutional, sociological, psychological, ethical, choice-theoretical, strategic, and game-theoretical treatments of rationality. This diversity of literature led to the creation of this volume. What does rationality mean? Was there some common core of meaning that held all of these seemingly disparate developments together, or were there discernable schools of thought with peculiarities that set them clearly apart from one another? The essays in this volume illustrate that diversity, and despite the variety of approaches there remains a common core of meaning that accommodates not so much a radically different set of concepts of rationality as a highly variegated array of methods and approaches to this subject. Contributors address topics of their choice on the concept of rationality in economics, and the selection of these contributors is meant to represent a variety of backgrounds and approaches.
Book Synopsis The Oxford Handbook of Rationality by : Alfred R. Mele
Download or read book The Oxford Handbook of Rationality written by Alfred R. Mele and published by Oxford University Press. This book was released on 2004-01-08 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rationality has long been a central topic in philosophy, crossing standard divisions and categories. It continues to attract much attention in published research and teaching by philosophers as well as scholars in other disciplines, including economics, psychology, and law. The Oxford Handbook of Rationality is an indispensable reference to the current state of play in this vital and interdisciplinary area of study. Twenty-two newly commissioned chapters by a roster of distinguished philosophers provide an overview of the prominent views on rationality, with each author also developing a unique and distinctive argument.
Book Synopsis Rationality in Extensive Form Games by : Andrés Perea
Download or read book Rationality in Extensive Form Games written by Andrés Perea and published by Springer Science & Business Media. This book was released on 2001-10-31 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with situations in which several persons reach decisions independently and the final consequence depends, potentially, upon each of the decisions taken. Such situations may be described formally by an extensive form game: a mathematical object which specifies the order in which decisions are to be taken, the information available to the decision makers at each point in time, and the consequence that results for each possible combination of decisions. A necessary requirement for rational behavior in such games is that each decision maker should reach a decision that is optimal, given his preferences over his own decisions. This requirement is far from sufficient, however, since every decision maker should in addition base his preferences upon the conjecture that his opponents will act optimally as well. It is this principle that distinguishes noncooperative game theory from one-person decision theory. The main purpose of Rationality in Extensive Form Games is to discuss different formalizations of this principle in extensive form games, such as backward induction, Nash equilibrium, forward induction and rationalizability, under the assumption that the decision makers' preferences are given by subjective expected utility functions. The various formalizations, or rationality criteria, are illustrated by examples, and the relationships among the different criteria are explored.
Book Synopsis Bounded Rationality and Industrial Organization by : Ran Spiegler
Download or read book Bounded Rationality and Industrial Organization written by Ran Spiegler and published by Oxford University Press. This book was released on 2011-02-18 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional economic theory assumes that consumers are fully rational, that they have well-defined preferences and easily understand the market environment. Yet, in fact, consumers may have inconsistent, context-dependent preferences or simply not enough brain-power to evaluate and compare complicated products. Thus the standard model of consumer behavior-which depends on an ideal market in which consumers are boundlessly rational-is called into question. While behavioral economists have for some time confirmed and characterized these inconsistencies, the logical next step is to examine the implications they have in markets. Grounded in key observations in consumer psychology, Bounded Rationality and Industrial Organization develops non-standard models of "boundedly rational" consumer behavior and embeds them into familiar models of markets. It then rigorously analyses each model in the tradition of microeconomic theory, leading to a richer, more realistic picture of consumer behavior. Ran Spiegler analyses phenomena such as exploitative price plans in the credit market, complexity of financial products and other obfuscation practices, consumer antagonism to unexpected price increases, and the role of default options in consumer decision making. Spiegler unifies the relevant literature into three main strands: limited ability to anticipate and control future choices, limited ability to understand complex market environments, and sensitivity to reference points. Although the challenge of enriching the psychology of decision makers in economic models has been at the frontier of theoretical research in the last decade, there has been no graduate-level, theory-oriented textbook to cover developments in the last 10-15 years. Thus, Bounded Rationality and Industrial Organization offers a welcome and crucial new understanding of market behavior-it challenges conventional wisdom in ways that are interesting and economically significant, and which in the end effect the well-being of all market participants.
Book Synopsis Models of Strategic Rationality by : Reinhard Selten
Download or read book Models of Strategic Rationality written by Reinhard Selten and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers collected in this volume relate to game theory. They aim at the elaboration and discussion of basic con cepts, at the analysis of specific applied models and at the evaluation of experimental evidence. A game is a mathematical model of a situation where several actors with different goals are engaged in strategic inter action. Game theory explores the nature and the consequence. s of rational behavior in games. With respect to several papers in this volume, it seems to be appropriate to comment on later developments. A list of some important references is given at the end of the intro duction. References already included in the collected pa pers are not repeated here. In casual conversation colleagues sometimes observe that the author on the one hand goes to extremes in the elabora tion of the consequences of Bayesian rationality and on the other hand strongly emphasizes the limited rationality of actual decision behavior. This seeming discrepancy is also expressed in the collection presented here. The author thinks that a sharp distinction should be made between nor ~ative and descriptive game theory. This position of "methodological dualism" has been expressed in a comment to Aumann's paper "What is game theory trying to accomplish?" (Aumann, 1985, Selten 1985) Normative game theory has the important task to explore the nature and the consequences of idealized full rationality in strategic interaction. This requires a thorough discuss ion of first principles. Empirical arguments are irrelevant here.
Book Synopsis The Limits of Rationality by : Karen Schweers Cook
Download or read book The Limits of Rationality written by Karen Schweers Cook and published by University of Chicago Press. This book was released on 2008-10-03 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prevailing economic theory presumes that agents act rationally when they make decisions, striving to maximize the efficient use of their resources. Psychology has repeatedly challenged the rational choice paradigm with persuasive evidence that people do not always make the optimal choice. Yet the paradigm has proven so successful a predictor that its use continues to flourish, fueled by debate across the social sciences over why it works so well. Intended to introduce novices to rational choice theory, this accessible, interdisciplinary book collects writings by leading researchers. The Limits of Rationality illuminates the rational choice paradigm of social and political behavior itself, identifies its limitations, clarifies the nature of current controversies, and offers suggestions for improving current models. In the first section of the book, contributors consider the theoretical foundations of rational choice. Models of rational choice play an important role in providing a standard of human action and the bases for constitutional design, but do they also succeed as explanatory models of behavior? Do empirical failures of these explanatory models constitute a telling condemnation of rational choice theory or do they open new avenues of investigation and theorizing? Emphasizing analyses of norms and institutions, the second and third sections of the book investigate areas in which rational choice theory might be extended in order to provide better models. The contributors evaluate the adequacy of analyses based on neoclassical economics, the potential contributions of game theory and cognitive science, and the consequences for the basic framework when unequal bargaining power and hierarchy are introduced.
Book Synopsis Bounded Rationality in Macroeconomics by : Thomas J. Sargent
Download or read book Bounded Rationality in Macroeconomics written by Thomas J. Sargent and published by Oxford University Press, USA. This book was released on 1993 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do people behave in new situations in which previous experience is not useful? The recent changes in Eastern Europe, for example, are unprecedented and there is not an available model on which to base the mechanisms that will govern the economics in this region. The concept of "bounded (orlimited) rationality" is being developed to analyze behavior in such situations. In this book Thomas Sargent describes and interprets the recent work in the area, especially in statistics, econometrics, networks and artificial intelligence. He focuses on examples designed to illustrate the issuesinvolved and the kinds of questions that are being asked and answered in this research. He points to further potential positive developments of the theory as well as some of its limitations.
Book Synopsis Rationality in Social Interactions by : Guido Olschewski
Download or read book Rationality in Social Interactions written by Guido Olschewski and published by Logos Verlag Berlin GmbH. This book was released on 2009 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of human decision making in social sciences is often based on a conception of rationality. This dissertation contains three microeconomic models, which directly build on the rationality assumption in economic theory. We model agents endowed with rational preferences and analyze how such preferences translate into decisions in a given social interaction. In particular, we present three different models: (1) Arrovian social choice theory with delegation as a feasible policy alternative; (2) Game theory and the existence of mental equilibrium in 2x2 games; (3) Information economics and its application to analyzing stakeholder participation in electronic health record networks.
Book Synopsis Rationality in Economics by : Vernon L. Smith
Download or read book Rationality in Economics written by Vernon L. Smith and published by Cambridge University Press. This book was released on 2007-11-05 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principal findings of experimental economics are that impersonal exchange in markets converges in repeated interaction to the equilibrium states implied by economic theory, under information conditions far weaker than specified in the theory. In personal, social, and economic exchange, as studied in two-person games, cooperation exceeds the prediction of traditional game theory. This book relates these two findings to field studies and applications and integrates them with the main themes of the Scottish Enlightenment and with the thoughts of F. A. Hayek: through emergent socio-economic institutions and cultural norms, people achieve ends that are unintended and poorly understood. In cultural changes, the role of constructivism, or reason, is to provide variation, and the role of ecological processes is to select the norms and institutions that serve the fitness needs of societies.
Download or read book Complex Economics written by Alan Kirman and published by Routledge. This book was released on 2010-09-13 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: The economic crisis is also a crisis for economic theory. Most analyses of the evolution of the crisis invoke three themes, contagion, networks and trust, yet none of these play a major role in standard macroeconomic models. What is needed is a theory in which these aspects are central. The direct interaction between individuals, firms and banks does not simply produce imperfections in the functioning of the economy but is the very basis of the functioning of a modern economy. This book suggests a way of analysing the economy which takes this point of view. The economy should be considered as a complex adaptive system in which the agents constantly react to, influence and are influenced by, the other individuals in the economy. In such systems which are familiar from statistical physics and biology for example, the behaviour of the aggregate cannot be deduced from the behaviour of the average, or "representative" individual. Just as the organised activity of an ants’ nest cannot be understood from the behaviour of a "representative ant" so macroeconomic phenomena should not be assimilated to those associated with the "representative agent". This book provides examples where this can clearly be seen. The examples range from Schelling’s model of segregation, to contributions to public goods, the evolution of buyer seller relations in fish markets, to financial models based on the foraging behaviour of ants. The message of the book is that coordination rather than efficiency is the central problem in economics. How do the myriads of individual choices and decisions come to be coordinated? How does the economy or a market, "self organise" and how does this sometimes result in major upheavals, or to use the phrase from physics, "phase transitions"? The sort of system described in this book is not in equilibrium in the standard sense, it is constantly changing and moving from state to state and its very structure is always being modified. The economy is not a ship sailing on a well-defined trajectory which occasionally gets knocked off course. It is more like the slime described in the book "emergence", constantly reorganising itself so as to slide collectively in directions which are neither understood nor necessarily desired by its components.
