Networks, Crowds, and Markets


Book Description

Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.




Networks, Markets & People


Book Description




Networks and Markets


Book Description

Networks and Markets argues that economists' knowledge of markets and sociologists' rich understanding of networks can and should be combined. Together they can help us achieve a more coherent view of economic life, where transactions follow both the logic of economic incentives and the established channels of personal relationships. Market exchange is impersonal, episodic, and carried out at arm's length. All that matters is how much the seller is asking, and how much the buyer is offering. An economic network, by contrast, is based upon more personalized and enduring relationships between people tied together by more than just price. Networks and Markets focuses on how the two concepts relate to each other: Are social networks an essential precondition for successful markets, or do networks arise naturally out of markets, as faceless traders build reputations and gain confidence in each other? The book includes contributions by both sociologists and economists, applying the concepts of markets and networks to concrete empirical phenomena. Among the topics analyzed, the book explains how, in Taiwan, South Korea, and Japan, firms combine into tightly-knit business blocs, how wholesalers in a Marseille fish market earn the loyalty of customers, and how ethnic retailers in the U.S. share valuable market information with other shopkeepers from their ethnic group. A response to each chapter discusses the issue from the standpoint of the other discipline. Sociologists are challenged to go beyond small-scale economic exchange and to integrate their concept of networks into a broader understanding of the economic system as a whole, while economists are challenged to consider the economic implications of network ties, which can be strong or weak, unconditional or highly contingent. This book proves that both economics and sociology provide stronger insights when they study markets and networks as parallel forms of exchange. But it also clarifies the healthy division of labor that remains between the two disciplines. Sociologists are adept at showing how markets are framed by social institutions; economists specialize in explaining how markets perform, taking the social context as a given. Networks and Markets showcases what each discipline does best and reveals where each discipline would do better by borrowing from the other.




The Wealth of Networks


Book Description

Describes how patterns of information, knowledge, and cultural production are changing. The author shows that the way information and knowledge are made available can either limit or enlarge the ways people create and express themselves. He describes the range of legal and policy choices that confront.




The Human Network


Book Description

Here is a fresh, intriguing, and, above all, authoritative book about how our sometimes hidden positions in various social structures—our human networks—shape how we think and behave, and inform our very outlook on life. Inequality, social immobility, and political polarization are only a few crucial phenomena driven by the inevitability of social structures. Social structures determine who has power and influence, account for why people fail to assimilate basic facts, and enlarge our understanding of patterns of contagion—from the spread of disease to financial crises. Despite their primary role in shaping our lives, human networks are often overlooked when we try to account for our most important political and economic practices. Matthew O. Jackson brilliantly illuminates the complexity of the social networks in which we are—often unwittingly—positioned and aims to facilitate a deeper appreciation of why we are who we are. Ranging across disciplines—psychology, behavioral economics, sociology, and business—and rich with historical analogies and anecdotes, The Human Network provides a galvanizing account of what can drive success or failure in life.




Networks, Markets, and the Pacific Rim


Book Description

Despite the negative press Asian economies have received in connection with the recent financial crisis, their record of spectacular growth over the past few decades remains irrefutable. In an effort to provide a rich, textured analysis of these economies, editor W. Mark Fruin presents a collection of essays that explores the wide range of network organizations that have been established in the Pacific Rim. Conventional studies of economic organization have tended to center on markets and hierarchies, the two forms of organization most common in the West. But today the world moves too quickly and too unpredictably for the idealized organizations of microeconomic theory to keep up. It is no accident that the region that has generated the world's most explosive economic growth is also the region where network organizations--sets of independent actors who cooperate frequently for mutual advantage--are most pervasive. Rapid economic, social, and technical changes favor the formation of network organizations, and vice versa. The contributors to this volume identify and elucidate four basic types of networks: naturally occurring networks, market replacing networks, hierarchy replacing networks, and market enhancing networks. They show how all of these have been shaped by the history, government, legal system, and culture of each country under consideration. These network organizations allow the authors to compare and contrast network forms in China, Japan, South Korea, Taiwan, and the United States according to features such as degrees of formalization, rule definition, and market conformance. The works collected here make an important contribution to a networks-markets- hierarchies framework that recognizes and emphasizes the diversity of organizational forms and behaviors. A unique resource for scholars and professionals in the fields of management and economics, this book enables a complex analysis of one of the world's fastest growing and most theoretically challenging regions.




Markets from Networks


Book Description

In Markets from Networks, one of America's most influential sociologists unveils a groundbreaking theory of the market economy. Arguing that most economists use overly abstract models of how the economy operates, Harrison White seeks a richer, more empirically based alternative. In doing so, he offers a more lucid, generalized treatment of the market models described in his important earlier work in order to show how any given market is situated in a broader exchange economy. White argues that the key to economic action is that producers seek market niches to maximize profit and minimize competition. As they do so, they base production decisions not only on anticipated costs from suppliers and anticipated demand from buyers, but also by looking at their competitors. In fact, White asserts, producers act less in response to actual demand than by anticipating it: they gauge where competitors have found demand and thus determine what they can do that is similar and yet different enough to give themselves a special niche. Building on these and related insights, White creates new mathematical models of how the economy works and how the interaction of its sectors creates mutual protection from the uncertainties of business. These models provide new ways of accounting for profits, prices, market shares, and other vital economic phenomena. He shows, for example, that prices are determined by the coalescing of local variables rather than set in terms of averages as implied by the ''law'' of supply and demand. The model of ''pure'' competition favored by economics is deficient, he concludes, as it fails to account for the varied circumstances of particular industries. Throughout, White draws extensively on case studies of American businesses and on recent mathematical and sociological work on networks. Rivaling standard economic theories with its rich empirical grounding, sheer originality, and scholarly rigor, Markets from Networks will resonate in economics and economic sociology for years to come.




Black Markets and Militants


Book Description

Understanding the political and socio-economic factors which give rise to youth recruitment into militant organizations is central to grasping some of the most important issues that affect the contemporary Middle East and Africa. In this book, Khalid Mustafa Medani explains why youth are attracted to militant organizations, examining the specific role economic globalization plays in determining how and why militant activists emerge. Based on extensive fieldwork, Medani offers an in-depth analysis of the impact of globalization, neoliberal reforms and informal economic networks on the rise and evolution of moderate and militant Islamist movements. In an original contribution to the study of Islamist and ethnic politics, he shows the importance of understanding when and under what conditions religious rather than other forms of identity become politically salient. This title is also available as Open Access on Cambridge Core.




Social and Economic Networks


Book Description

Networks of relationships help determine the careers that people choose, the jobs they obtain, the products they buy, and how they vote. The many aspects of our lives that are governed by social networks make it critical to understand how they impact behavior, which network structures are likely to emerge in a society, and why we organize ourselves as we do. In Social and Economic Networks, Matthew Jackson offers a comprehensive introduction to social and economic networks, drawing on the latest findings in economics, sociology, computer science, physics, and mathematics. He provides empirical background on networks and the regularities that they exhibit, and discusses random graph-based models and strategic models of network formation. He helps readers to understand behavior in networked societies, with a detailed analysis of learning and diffusion in networks, decision making by individuals who are influenced by their social neighbors, game theory and markets on networks, and a host of related subjects. Jackson also describes the varied statistical and modeling techniques used to analyze social networks. Each chapter includes exercises to aid students in their analysis of how networks function. This book is an indispensable resource for students and researchers in economics, mathematics, physics, sociology, and business.




Markets, Hierarchies and Networks


Book Description

This interdisciplinary reader provides a distinctive introduction to the way social, political and economic life is coordinated. It brings together three quite different models of coordination - markets, hierarchies and networks - and places them into a comparative framework, presenting a comprehensive and insightful overview of social coordination. The articles dealing with each model explore the characteristics of that coordinating mechanism, outlining key theoretical issues and drawing on various empirical examples. The final section shows how these models can be compared and contrasted. It also assesses the respective strengths, weaknesses and limitations of each model. Markets, Hierarchies and Networks is a set
