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.




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.




Social and Economic Networks in Cooperative Game Theory


Book Description

Social and Economic Networks in Cooperative Game Theory presents a coherent overview of theoretical literature that studies the influence and formation of networks in social and economic situations in which the relations between participants who are not included in a particular participant's network are not of consequence to this participant. The material is organized in two parts. In Part I the authors concentrate on the question how network structures affect economic outcomes. Part II of the book presents the formation of networks by agents who engage in a network-formation process to be able to realize the possible gains from cooperation.

Economic Networks


Book Description

Social relations are crucial for understanding diverse economic actions and a network perspective is central to that explanation. Simple exchanges involving money, labor, and commodities combine into complexly connected systems. Economic networks span many levels of analysis, from persons (consumers, employees), to groups (households, workteams), organizations (corporations, interest groups), populations (industries, markets) and the rapidly expanding global economic system. David Knoke blends network theories from a range of disciplines and empirical studies of domestic and international economies to illuminate how economic activity is embedded in and constrained by social ties among economic actors. Social capital, in the form of connections to others holding valuable resources, is vital for finding a job, buying a car, creating a new industry, or triggering a global financial crisis. In nontechnical terms the author explicates the core network concepts, measures, and analysis methods behind these phenomena. The book also includes many striking network diagrams to provide visual insights into complex structural patterns. This accessible book offers an invaluable critique for both undergraduate and graduate students in economic sociology and social network analysis courses who seek a better understanding of the multifaceted economic webs in which we are all entangled.

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.




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 Oxford Handbook of the Economics of Networks


Book Description

The Oxford Handbook of the Economics of Networks represents the frontier of research into how and why networks they form, how they influence behavior, how they help govern outcomes in an interactive world, and how they shape collective decision making, opinion formation, and diffusion dynamics. From a methodological perspective, the contributors to this volume devote attention to theory, field experiments, laboratory experiments, and econometrics. Theoretical work in network formation, games played on networks, repeated games, and the interaction between linking and behavior is synthesized. A number of chapters are devoted to studying social process mediated by networks. Topics here include opinion formation, diffusion of information and disease, and learning. There are also chapters devoted to financial contagion and systemic risk, motivated in part by the recent financial crises. Another section discusses communities, with applications including social trust, favor exchange, and social collateral; the importance of communities for migration patterns; and the role that networks and communities play in the labor market. A prominent role of networks, from an economic perspective, is that they mediate trade. Several chapters cover bilateral trade in networks, strategic intermediation, and the role of networks in international trade. Contributions discuss as well the role of networks for organizations. On the one hand, one chapter discusses the role of networks for the performance of organizations, while two other chapters discuss managing networks of consumers and pricing in the presence of network-based spillovers. Finally, the authors discuss the internet as a network with attention to the issue of net neutrality.




Connections


Book Description

Networks pervade social and economic life, and they play a prominent role in explaining a huge variety of social and economic phenomena. Standard economic theory did not give much credit to the role of networks until the early 1990s, but since then the study of the theory of networks has blossomed. At the heart of this research is the idea that the pattern of connections between individual rational agents shapes their actions and determines their rewards. The importance of connections has in turn motivated the study of the very processes by which networks are formed. In Connections, Sanjeev Goyal puts contemporary thinking about networks and economic activity into context. He develops a general framework within which this body of research can be located. In the first part of the book he demonstrates that location in a network has significant effects on individual rewards and that, given this, it is natural that individuals will seek to form connections to move the network in their favor. This idea motivates the second part of the book, which develops a general theory of network formation founded on individual incentives. Goyal assesses the robustness of current research findings and identifies the substantive open questions. Written in a style that combines simple examples with formal models and complete mathematical proofs, Connections is a concise and self-contained treatment of the economic theory of networks, one that should become the natural source of reference for graduate students in economics and related disciplines.
