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. -
Slope Takers in Anonymous Markets"
Slope Takers in Anonymous Markets Marek Weretka,y 29th May 2011 Abstract In this paper, we study interactions among large agents trading in anonymous markets. In such markets, traders have no information about other traders’payo¤s, identities or even submitted orders. To trade optimally, each trader estimates his own price impact from the available data on past prices as well as his own trades and acts optimally, given such a simple (residual supply) representation of the residual mar- ket. We show that in a Walrasian auction, which is known to have a multiplicity of Nash equilibria that if all traders independently estimate and re-estimate price im- pacts, market interactions converge to a particular Nash equilibrium. Consequently, anonymity and learning argument jointly provide a natural selection argument for the Nash equilibrium in a Walrasian auction. We then study the properties of such focal equilibrium. JEL clasi…cation: D43, D52, L13, L14 Keywords: Walrasian Auction, Anonymous Thin Markets, Price impacts 1 Introduction Many markets, e.g., markets for …nancial assets are anonymous. In such markets inform- ation of each individual trader is restricted to own trades and commonly observed market price. Traders have no information about other traders’payo¤s, identities or submitted or- ders.

Understanding Emotions in Electronic Auctions: Insights from Neurophysiology
Understanding Emotions in Electronic Auctions: Insights from Neurophysiology Marc T. P. Adam and Jan Krämer Abstract The design of electronic auction platforms is an important field of electronic commerce research. It requires not only a profound understanding of the role of human cognition in human bidding behavior but also of the role of human affect. In this chapter, we focus specifically on the emotional aspects of human bidding behavior and the results of empirical studies that have employed neurophysiological measurements in this regard. By synthesizing the results of these studies, we are able to provide a coherent picture of the role of affective processes in human bidding behavior along four distinct theoretical pathways. 1 Introduction Electronic auctions (i.e., electronic auction marketplaces) are information systems that facilitate and structure the exchange of products and services between several potential buyers and sellers. In practice, electronic auctions have been employed for a wide range of goods and services, such as commodities (e.g., Internet consumer auction markets, such as eBay.com), perishable goods (e.g., Dutch flower markets, such as by Royal FloraHolland), consumer services (e.g., procurement auction markets, such as myhammer.com), or property rights (e.g., financial double auction markets such as NASDAQ). In this vein, a large share of our private and commercial economic activity is being organized through electronic auctions today (Adam et al. 2017;Kuetal.2005). Previous research in information systems, economics, and psychology has shown that the design of electronic auctions has a tremendous impact on the auction M. T. P.

There Are No Pequots on the Plains: Assessing the Success of Indian Gaming Kathryn R.L. Rand* INTRODUCTION “We had tried poverty for 200 years, so we decided to try something else.”1 Ray Halbritter was referring to his own tribe, the Oneida Indian Nation of New York, but the sentiment might have applied to each of the nearly 150 tribes that decided to pur- sue casino-style gaming during the 1990s as a means of tribal eco- nomic development. For the last decade, gaming tribes across the country have lauded the financial and social successes of their casinos. The tribes’ accounts largely have been corroborated by empirical research. In 1999, the National Gambling Impact Study Commission (NGISC) reported that Indian gaming has allowed tribes “to take unprecedented steps to begin to address the eco- nomic as well as social problems on their own.”2 In addition, a study conducted by the Harvard Project on American Indian Eco- nomic Development concluded in 2000 that both surrounding lo- calities and tribes benefit substantially from tribal casinos, particularly in the poorest areas of the country.3 Indeed, leading tribal gaming researchers recently concluded “the idea that the consequences of Indian gaming are largely negative, either for In- * Assistant Professor, University of North Dakota School of Law. -

Over a third believed that the range of services and programmes at the BBC is about right (37%). Figure 1: Quantitative research - Balance of services and programmes 2.
