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.

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.

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.

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.

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

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.

A study of the structure, growth, and future of transnational human travel and communication Increasingly, people travel and communicate across borders. Yet, we still know little about the overall structure of this transnational world. Is it really a fully globalized world in which everything is linked, as popular catchphrases like “global village” suggest? Through a sweeping comparative analysis of eight types of mobility and communication among countries worldwide—from migration and tourism to Facebook friendships and phone calls—Mapping the Transnational World demonstrates that our behavior is actually regionalized, not globalized. Emanuel Deutschmann shows that transnational activity within world regions is not so much the outcome of political, cultural, or economic factors, but is driven primarily by geographic distance. He explains that the spatial structure of transnational human activity follows a simple mathematical function, the power law, a pattern that also fits the movements of many other animal species on the planet. Moreover, this pattern remained extremely stable during the five decades studied—1960 to 2010. Unveiling proximity-induced regionalism as a major feature of planet-scale networks of transnational human activity, Deutschmann provides a crucial corrective to several fields of research. Revealing why a truly global society is unlikely to emerge, Mapping the Transnational World highlights the essential role of interaction beyond borders on a planet that remains spatially fragmented.
