Uniqueness and Symmetry in Bargaining Theories of Justice
Philos Stud DOI 10.1007/s11098-013-0121-y Uniqueness and symmetry in bargaining theories of justice John Thrasher Ó Springer Science+Business Media Dordrecht 2013 Abstract For contractarians, justice is the result of a rational bargain. The goal is to show that the rules of justice are consistent with rationality. The two most important bargaining theories of justice are David Gauthier’s and those that use the Nash’s bargaining solution. I argue that both of these approaches are fatally undermined by their reliance on a symmetry condition. Symmetry is a substantive constraint, not an implication of rationality. I argue that using symmetry to generate uniqueness undermines the goal of bargaining theories of justice. Keywords David Gauthier Á John Nash Á John Harsanyi Á Thomas Schelling Á Bargaining Á Symmetry Throughout the last century and into this one, many philosophers modeled justice as a bargaining problem between rational agents. Even those who did not explicitly use a bargaining problem as their model, most notably Rawls, incorporated many of the concepts and techniques from bargaining theories into their understanding of what a theory of justice should look like. This allowed them to use the powerful tools of game theory to justify their various theories of distributive justice. The debates between partisans of different theories of distributive justice has tended to be over the respective benefits of each particular bargaining solution and whether or not the solution to the bargaining problem matches our pre-theoretical intuitions about justice. There is, however, a more serious problem that has effectively been ignored since economists originally J. -
Market Power and Regulation
THE PRIZE IN ECONOMIC SCIENCES 2014 POPULAR SCIENCE BACKGROUND Market power and regulation Jean Tirole is one of the most infuential economists of our time. He has made important theoretical research contributions in a number of areas, but most of all he has clarifed how to understand and regulate industries with a few powerful frms. Tirole is awarded this year’s prize for his analysis of market power and regulation. Regulation is difficult Which activities should be conducted as public services and which should be left to private frms is a question that is always relevant. Many governments have opened up public monopolies to private stakeholders. This has applied to industries such as railways, highways, water, post and telecom- munications – but also to the provision of schooling and healthcare. The experiences resulting from these privatizations have been mixed and it has often been more difcult than anticipated to get private frms to behave in the desired way. There are two main difculties. First, many markets are dominated by a few frms that all infuence prices, volumes and quality. Traditional economic theory does not deal with this case, known as an oligopoly, instead it presupposes a single monopoly or what is known as perfect competition. The second difculty is that the regulatory authority lacks information about the frms’ costs and the quality of the goods and services they deliver. This lack of knowledge often provides regulated frms with a natural advantage. Before Tirole In the 1980s, before Tirole published his frst work, research into regulation was relatively sparse, mostly dealing with how the government can intervene and control pricing in the two extremes of monopoly and perfect competition. -

Putting Auction Theory to Work
Putting Auction Theory to Work Paul Milgrom With a Foreword by Evan Kwerel © 2003 “In Paul Milgrom's hands, auction theory has become the great culmination of game theory and economics of information. Here elegant mathematics meets practical applications and yields deep insights into the general theory of markets. Milgrom's book will be the definitive reference in auction theory for decades to come.” —Roger Myerson, W.C.Norby Professor of Economics, University of Chicago “Market design is one of the most exciting developments in contemporary economics and game theory, and who can resist a master class from one of the giants of the field?” —Alvin Roth, George Gund Professor of Economics and Business, Harvard University “Paul Milgrom has had an enormous influence on the most important recent application of auction theory for the same reason you will want to read this book – clarity of thought and expression.” —Evan Kwerel, Federal Communications Commission, from the Foreword For Robert Wilson Foreword to Putting Auction Theory to Work Paul Milgrom has had an enormous influence on the most important recent application of auction theory for the same reason you will want to read this book – clarity of thought and expression. In August 1993, President Clinton signed legislation granting the Federal Communications Commission the authority to auction spectrum licenses and requiring it to begin the first auction within a year. With no prior auction experience and a tight deadline, the normal bureaucratic behavior would have been to adopt a “tried and true” auction design. But in 1993 there was no tried and true method appropriate for the circumstances – multiple licenses with potentially highly interdependent values. -
A Brief Appraisal of Behavioral Economists' Plea for Light Paternalism
Brazilian Journal of Political Economy, vol 32, nº 3 (128), pp 445-458, July-September/2012 Freedom of choice and bounded rationality: a brief appraisal of behavioral economists’ plea for light paternalism ROBERTA MURAMATSU PATRÍCIA FONSECA* Behavioral economics has addressed interesting positive and normative ques- tions underlying the standard rational choice theory. More recently, it suggests that, in a real world of boundedly rational agents, economists could help people to im- prove the quality of their choices without any harm to autonomy and freedom of choice. This paper aims to scrutinize available arguments for and against current proposals of light paternalistic interventions mainly in the domain of intertemporal choice. It argues that incorporating the notion of bounded rationality in economic analysis and empirical findings of cognitive biases and self-control problems cannot make an indisputable case for paternalism. Keywords: freedom; choice; bounded rationality; paternalism; behavioral eco- nomics. JEL Classification: B40; B41; D11; D91. So the immediate problem in Libertarian Paternalism is the fatuity of its declared motivation Very few libertarians have maintained what Thaler and Sunstein suggest they maintain, and indeed many of the leading theorists have worked with ideas in line with what Thaler and Sunstein have to say about man’s nature Thaler and Sunstein are forcing an open door Daniel Klein, Statist Quo Bias, Economic Journal Watch, 2004 * Professora doutora da Universidade Presbiteriana Mackenzie e do Insper, e-mail: rmuramatsu@uol. com.br; Pesquisadora independente na área de Economia Comportamental e Psicologia Econômica, e-mail [email protected].

John Von Neumann Between Physics and Economics: a Methodological Note
Review of Economic Analysis 5 (2013) 177–189 1973-3909/2013177 John von Neumann between Physics and Economics: A methodological note LUCA LAMBERTINI∗y University of Bologna A methodological discussion is proposed, aiming at illustrating an analogy between game theory in particular (and mathematical economics in general) and quantum mechanics. This analogy relies on the equivalence of the two fundamental operators employed in the two fields, namely, the expected value in economics and the density matrix in quantum physics. I conjecture that this coincidence can be traced back to the contributions of von Neumann in both disciplines. Keywords: expected value, density matrix, uncertainty, quantum games JEL Classifications: B25, B41, C70 1 Introduction Over the last twenty years, a growing amount of attention has been devoted to the history of game theory. Among other reasons, this interest can largely be justified on the basis of the Nobel prize to John Nash, John Harsanyi and Reinhard Selten in 1994, to Robert Aumann and Thomas Schelling in 2005 and to Leonid Hurwicz, Eric Maskin and Roger Myerson in 2007 (for mechanism design).1 However, the literature dealing with the history of game theory mainly adopts an inner per- spective, i.e., an angle that allows us to reconstruct the developments of this sub-discipline under the general headings of economics. My aim is different, to the extent that I intend to pro- pose an interpretation of the formal relationships between game theory (and economics) and the hard sciences. Strictly speaking, this view is not new, as the idea that von Neumann’s interest in mathematics, logic and quantum mechanics is critical to our understanding of the genesis of ∗I would like to thank Jurek Konieczny (Editor), an anonymous referee, Corrado Benassi, Ennio Cavaz- zuti, George Leitmann, Massimo Marinacci, Stephen Martin, Manuela Mosca and Arsen Palestini for insightful comments and discussion. -
Introduction to Game Theory
Economic game theory: a learner centred introduction Author: Dr Peter Kührt Introduction to game theory Game theory is now an integral part of business and politics, showing how decisively it has shaped modern notions of strategy. Consultants use it for projects; managers swot up on it to make smarter decisions. The crucial aim of mathematical game theory is to characterise and establish rational deci- sions for conflict and cooperation situations. The problem with it is that none of the actors know the plans of the other “players” or how they will make the appropriate decisions. This makes it unclear for each player to know how their own specific decisions will impact on the plan of action (strategy). However, you can think about the situation from the perspective of the other players to build an expectation of what they are going to do. Game theory therefore makes it possible to illustrate social conflict situations, which are called “games” in game theory, and solve them mathematically on the basis of probabilities. It is assumed that all participants behave “rationally”. Then you can assign a value and a probability to each decision option, which ultimately allows a computational solution in terms of “benefit or profit optimisation”. However, people are not always strictly rational because seemingly “irrational” results also play a big role for them, e.g. gain in prestige, loss of face, traditions, preference for certain colours, etc. However, these “irrational" goals can also be measured with useful values so that “restricted rational behaviour” can result in computational results, even with these kinds of models. -

A Network of Excellence in Economic Theory Prepared By
Foundations of Game Theoretic Understanding of Socio-Economic Phenomena; A Network of Excellence in Economic Theory Prepared by Myrna Wooders, Department of Economics, University of Warwick Gibbet Hill Road, Coventry, CV4 7AL, UK [email protected] Applicable Instrument: Network of Excellence Sub-Thematic Priority most relevant to the topic: 1.1.7 Citizens and Governance in a Knowledge-based society Other relevant Sub-Thematic Priorities: 1.1.7.i Knowledge-based society and social cohesion 1.1.7.ii Citizenship, democracy and new forms of governance Summary: This EoI is for a network in game theory and economic theory, including evolutionary approaches. While the proposal relates to applications of theory, the main motivation and thrust is in a network of excellence in pure theory. Like research in theoretical physics or on the human genome, fundamental game theory and economic theory is not primarily motivated by immediate applications or by current policy issues. Instead, it is motivated by scientific intellectual curiosity. Because this curiosity arises from a quest towards a deeper understanding of the world around us, it is anticipated, however, that there will be applications of great significance – recall that the multi-billion dollar outcomes of auctions of spectrum in the US were guided by game theory. In addition, fundamental scientific theory, because of its search for understanding that will have broad consequences and transcend national boundaries, is appropriately funded by at the European Union level. The network aims to embrace the leading researchers in economic theory and game theory and strengthen Europe’s position as a leader in economic research. -
