Is morality rational? In this book Gauthier argues that moral principles are principles of rational choice. He proposes a principle whereby choice is made on an agreed basis of cooperation, rather than according to what would give an individual the greatest expectation of value. He shows that such a principle not only ensures mutual benefit and fairness, thus satisfying the standards of morality, but also that each person may actually expect greater utility by adhering to morality, even though the choice (...) did not have that end primarily in view. In resolving what may appear to be a paradox, the author establishes morals on the firm foundation of reason. Gauthier's argument includes an account of value, linking it to preference and utility; a discussion of the curcumstances in which morality is unnecessary; and an application of morals by agreement to relations between peoples at different levels of development and different generations. Finally, he reflects on the assumptions about individuality and community made by his account of rationality and morality. (shrink)

The 'Evolution of Cooperation' addresses a simple yet age-old question; If living things evolve through competition, how can cooperation ever emerge? Despite the abundant evidence of cooperation all around us, there existed no purely naturalistic answer to this question until 1979, when Robert Axelrod famously ran a computer tournament featuring a standard game-theory exercise called The Prisoner's Dilemma. To everyone's surprise, the program that won the tournament, named Tit for Tat, was not only the simplest but the most "cooperative" entrant. (...) This unexpected victory proved that cooperation - one might even say altruism - is mathematically possible and therefore needs no hidden hand or divine agent to create and sustain it. A great roadblock to the understanding of all sorts of behavior was at last removed. The updated edition includes an extensive new chapter on cooperation in cancer cells and among terrorist organizations. (shrink)

The paper presents a simulation of the dynamics of impersonal trust. It shows how a “trust and reciprocate” norm can emerge and stabilize in populations of conditional cooperators. The norm, or behavioral regularity, is not to be identified with a single strategy. It is instead supported by several conditional strategies that vary in the frequency and intensity of sanctions.

Economic man seeks to maximize utility. The rationality of economic man is assumed, and is identified with the aim of utility-maximization. But may rational activity correctly be identified with maximizing activity? The object of this essay is to explore, and in part to answer, this question.This is not an issue solely, or perhaps even primarily, about the presuppositions of economics. The two great modern schools of moral and political thought in the English-speaking world, the contractarian and the utilitarian, identify rationality (...) with maximization, and bring morality into their equations as well. To the contractarian, rational man enters civil society to maximize his expectation of well-being, and morality is that system of principles of action which rational men collectively adopt to maximize their well-being. To the utilitarian, the rational and moral individual seeks the maximum happiness of mankind, with which he identifies his own maximum happiness. (shrink)

This major study of Hobbes's political philosophy draws on recent developments in game and decision theory to explore whether the thrust of the argument in Leviathan, that it is in the interests of the people to create a ruler with absolute power, can be shown to be cogent. Professor Hampton has written a book of vital importance to political philosophers, political and social scientists, and intellectual historians.

Employing the techniques of modern economic analysis, Professor Buchanan reveals the conceptual basis of an individual's social rights by examining the ...

This essay seeks to give a contractarian foundation to the concept of Corporate Social Responsibility (CSR), meant as an extended model of corporate governance of the firm. It focuses on justification according to the contractarian point of view (leaving compliance and implementation problems to a related article, [Sacconi 2004b, forthcoming in the Journal of Business Ethics]). It begins by providing a definition of CSR as an extended model of corporate governance, based on the fiduciary duties owed to all the firm’s (...) stakeholders. Then, by establishing the basic context of incompleteness of contracts and abuse of authority, it analyses how the extended view of corporate governance arises directly from criticism of the contemporary neo-institutional economic theory of the firm. Thereafter, an application of the theory of bargaining games is used to deduce the structure of a multi-stakeholder firm, on the basis of the idea of a constitutional contract, which satisfies basic requirements of impartial justification and accordance with intuitions of social justice. This is a sequential model of constitutional bargaining, whereby a constitution is first chosen, and then a post-constitutional coalition game is played. On the basis of the unique solution given to each step in the bargaining model, the quest for a prescriptive theory of governance and strategic management is accomplished, so that I am able to define an objective-function for the firm consistent with the idea of CSR. Finally, a contractarian potential explanation for the emergence of the multi-fiduciary firm is provided. (shrink)

Brian Skyrms, author of the successful Evolution of the Social Contract has written a sequel. The book is a study of ideas of cooperation and collective action. The point of departure is a prototypical story found in Rousseau's A Discourse on Inequality. Rousseau contrasts the pay-off of hunting hare where the risk of non-cooperation is small but the reward is equally small, against the pay-off of hunting the stag where maximum cooperation is required but where the reward is so much (...) greater. Thus, rational agents are pulled in one direction by considerations of risk and in another by considerations of mutual benefit. Written with Skyrms's characteristic clarity and verve, this intriguing book will be eagerly sought out by students and professionals in philosophy, political science, economics, sociology and evolutionary biology.

This essay seeks to give a contractarian foundation to the concept of Corporate Social Responsibility (CSR), meant as an extended model of corporate governance of the firm. Whereas, justificatory issues have been discussed in a related paper (Sacconi, L.: 2006b, this journal), in this essay I focus on the implementation of and compliance with this normative model. The theory of reputation games, with reference to the basic game of trust, is introduced in order to make sense of self-regulation as a (...) way to implement the social contract on the multi-fiduciary model of corporate governance. This affords understanding of why self-regulation, meant as mere recourse to a long-run strategy in a repeated trust game, fails. Two basic problems for the functioning of the reputation mechanism are examined: the cognitive fragility problem, and the motivational problem. As regards the cognitive fragilities of reputation (which result from the impact of unforeseen contingencies and from bounded rationality), the paper develops the logic and the structure that self-regulatory norms must satisfy if they are to serve as gap-filling tools with which to remedy cognitive limitations in the reputation mechanism. The motivation problem then arises from the possibility of sophisticated abuse by the firm. Developed in this case is an entirely new application of the theory of conformism-and-reciprocity-based preferences, the result of which is that the stakeholders refuse to acquiesce to sophisticated abuse on the part of the firm.

In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are most (...) likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies. (shrink)

In fact, it requires two major social institutions--morality and government--working in a coordinated fashion to do so. This is one of the main themes of Hobbes's philosophy that will be developed in this book.

Recent theorists have suggested that human altruism toward non-family members evolved because of the tremendous benefits of reciprocity. Developing further the notion that evolutionary theory can help to explain moral sentiments, Howard Kahane proposes that a sense of fair play is essential to ethics and argues that moral obligation, too narrowly construed, prevents us from living rationally. He brings his account of fair play to bear on the ethics of various domains of social life including friendship, taxes, civil rights, and (...) nation states. (shrink)

David Gauthier is one of the most outstanding and influential philosophers working in moral theory today, and his book Morals by Agreement has established him as a preeminent defender of contractarian moral theory. This volume brings together a selection of his best essays on contractarianism, many of which have become difficult to find.
