Minority games are simple mathematical models initially designed to understand the co-operative phenomena observed in markets. Their core ingredients are large numbers of interacting decision-making agents, each aiming for personal gain in an artificial `market' by trying to anticipate (on the basis of incomplete information, and with an element of irrationality) the actions of others. Gain is made by those who subsequently find themselves in the minority group, e.g. those who end up buying when most wish to sell or vice versa. Aimed at researchers and students in physics, mathematics and economics this text describes the mathematical theory of Minority Games from a statistical mechanics viewpoint. It provides a detailed and explicit introduction to the advanced mathematical analysis of these models, describes the potential and restrictions of physical methods in solving agent based market models, and outlines how different mathematical approaches are related.
In this work, which is aimed at researchers in mathematics, physics, and economics, the author describes the mathematical theory of minority games, and focuses on one of three recognised approaches to this phenomenon.
The Minority Game is a physicist's attempt to explain market behaviour by the interaction between traders. With a minimal set of ingredients and drastic assumptions, this model reproduces market ecology among different types of traders. Its emphasis is on speculative trading and information flow. The book first describes the philosophy lying behind the conception of the Minority Game in 1997, and includes in particular a discussion about the El Farol bar problem. It then reviews the main steps in later developments, including both the theory and its applications to market phenomena. 'Minority Games' gives a colourful and stylized, but also realistic picture of how financial markets operate.

This book collects recent results in systems whose evolutions are dominated by fluctuations, driven systems in which the way to dissipate driving forces is relevant, and systems in which disorder induces highly non-trivial dynamics leading naturally to questions of computational complexity. Topics of the 14 papers include multiplicative noise in non-equilibrium phase transitions, the stochastic population dynamics of spiking neurons, anomalous velocity distributions in elastic Maxwell gases, universality issues in surface kinetic roughening of thin solid films, and multi-state neural networks based upon spin glasses. Some of the chapters have appeared in the arXiv.org database. No information is given about the authors. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).
Winner, 2020 American Book Award, given by the Before Columbus Foundation How games have been used to establish and combat Asian American racial stereotypes As Pokémon Go reshaped our neighborhood geographies and the human flows of our cities, mapping the virtual onto lived realities, so too has gaming and game theory played a role in our contemporary understanding of race and racial formation in the United States. From the Chinese Exclusion Act and Japanese American internment to the model minority myth and the globalization of Asian labor, Tara Fickle shows how games and game theory shaped fictions of race upon which the nation relies. Drawing from a wide range of literary and critical texts, analog and digital games, journalistic accounts, marketing campaigns, and archival material, Fickle illuminates the ways Asian Americans have had to fit the roles, play the game, and follow the rules to be seen as valuable in the US. Exploring key moments in the formation of modern US race relations, The Race Card charts a new course in gaming scholarship by reorienting our focus away from games as vehicles for empowerment that allow people to inhabit new identities, and toward the ways that games are used as instruments of soft power to advance top-down political agendas. Bridging the intellectual divide between the embedded mechanics of video games and more theoretical approaches to gaming rhetoric, Tara Fickle reveals how this intersection allows us to overlook the predominance of game tropes in national culture. The Race Card reveals this relationship as one of deep ideological and historical intimacy: how the games we play have seeped into every aspect of our lives in both monotonous and malevolent ways.
This book serves as a concise introduction to the state-of-the-art of spin glass theory. The collection of review papers are written by leading experts in the field and cover the topic from a wide variety of angles. The book will be useful to both graduate students and young researchers, as well as to anyone curious to know what is going on in this exciting area of mathematical physics.
The financial crash of 2007-2008 and the subsequent global economic crisis have raised questions about the viability of capitalism and the desirability of alternative types of economic system. In this context, Keynesian and Marxist ideas in particular have become more popular. These two approaches, along with some other heterodox perspectives, agree on the need for institutional analysis and for better institutions and governance in order to promote economic development. This volume poses fundamental institutional, evolutionary and ontological questions relating to the emergence of a new mode of governance after the financial crisis. The book argues that, contrary to the recent austerity policies implemented in the EU in particular, a new level of government involvement is required in order to keep aggregate demand stable, make full employment possible, and create a transparent financial sector, serving the real economy and encouraging productive investments. This book will be of interest to students, researchers and policy makers working in the areas of finance, institutional economics, development economics and international political economy.
Reviews the econophysics researches on the fluctuations in stock, forex and other markets. Including some historical perspectives as well as some comments and debates on issues in econophysics research, this book also discusses the statistical modeling of markets, using various agent-based game theoretical approaches, and their scaling analysis.
This book is a course in methods and models rooted in physics and used in modelling economic and social phenomena. It covers the discipline of econophysics, which creates an interface between physics and economics. Besides the main theme, it touches on the theory of complex networks and simulations of social phenomena in general. After a brief historical introduction, the book starts with a list of basic empirical data and proceeds to thorough investigation of mathematical and computer models. Many of the models are based on hypotheses of the behaviour of simplified agents. These comprise strategic thinking, imitation, herding, and the gem of econophysics, the so-called minority game. At the same time, many other models view the economic processes as interactions of inanimate particles. Here, the methods of physics are especially useful. Examples of systems modelled in such a way include books of stock-market orders, and redistribution of wealth among individuals. Network effects are investigated in the interaction of economic agents. The book also describes how to model phenomena like cooperation and emergence of consensus. The book will be of benefit to graduate students and researchers in both Physics and Economics.
