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.

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.

The seventeenth century saw an influx of immigrants to the heavily Puritan Massachusetts Bay Colony. This book redefines the role that non-Puritans and non-English immigrants played in the social and economic development of Massachusetts. Marsha Hamilton shows how non-Puritan English, Scots, and Irish immigrants, along with Channel Islanders, Huguenots, and others, changed the social and economic dynamic of the colony. A chronic labor shortage in early Massachusetts allowed many non-Puritans to establish themselves in the colony, providing a foundation upon which later immigrants built transatlantic economic networks. Scholars of the era have concluded that these “strangers” assimilated into the Puritan structure and had little influence on colonial development; however, through an in-depth examination of each group’s activity in local affairs, Marsha Hamilton asserts a much different conclusion. By mining court, town, and company records, letters, and public documents, Hamilton uncovers the impact that these immigrants had on the colony, not only by adding to the diversity and complexity of society but also by developing strong economic networks that helped bring the Bay Colony into the wider Atlantic world. These groups opened up important mercantile networks between their own homelands and allies, and by creating their own communities within larger Puritan networks, they helped create the provincial identity that led the colony into the eighteenth century.

It is surprising to think that in today’s rapidly evolving world of technology, over half of the globe still does not have access to high speed internet. Creating community wireless networks has in the past been a way to provide remote communities with internet and network access. Social and Economic Effects of Community Wireless Networks and Infrastructures highlights the successes of community wireless networks but also boldly addresses the potential risk factors and broader socioeconomic concerns. This publication’s exploration of previous successes and failures, various designs, and potential challenges with CWNs makes it a valuable resource for researchers, practitioners, vendors, and activists.

This volume sheds light on the current state of complex networks and nonlinear dynamics applied to the understanding of economic and social phenomena ranging from geographical economics to macroeconomics and finance, and its purpose is to give readers an overview of several interesting topics for research at an intermediate level. Three different and interdisciplinary, but complementary, aspects of networks are put together in a single piece, namely: (i) complex networks theory, (ii) applied network analysis to social and economic interrelations, and (iii) dynamical evolution of systems and networks. The volume includes contributions from excellent scholars in economics and social sciences as well as leading experts in the fields of complex networks and nonlinear dynamics.

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.

Social and economic networks are becoming increasingly important, both on the internet and otherwise. Agents in these networks possess limited information, and interact chiefly with their local neighborhood. Yet these networks have proven remarkably effective at the aggregation of 'information' at massive scales. It is of great scientific and commercial interest to build realistic models for phenomena in networks of agents. This thesis focuses on understanding the dynamics of interaction between agents on social and economic networks, and developing general theoretical tools in this context. Exchange networks model the behavior of a set of players who need to reach pairwise agreements for mutual benefit, as in the labor market, the housing market and the 'market' for social relationships. A crucial but little understood aspect of exchange networks is the dynamics of bargaining between players. We present a natural model of the bargaining dynamics in general networks, and show rapid convergence to certain socially optimal outcomes. We also describe internet-based experiments on bargaining in networks, which are the largest such experiments to date. In many contexts, agents 'learn' behavior from interaction with friends/neighbors on a network. We call this phenomenon 'social learning'. We focus on models of repeated interaction, with agents 'voting' in a series of rounds on some issue of interest. Votes in the initial round are based on 'private signals', whereas votes in future rounds incorporate knowledge of previous votes cast by friends. Thus, information is aggregated by the network via iterative updates. We consider two different models of iterative learning. A very simple model is 'majority dynamics' where agents choose their vote based on the majority of neighbors' votes in the previous round. We analyze this model on regular trees. At the other extreme is iterative Bayesian learning: a fully rational model introduced by Gale and Kariv (2003). We introduce new algorithms for this model, challenging a widespread belief that it is computationally intractable. We develop a novel technique -- the 'dynamic cavity method', which serves as a key analytical and algorithmic tool, and is generally applicable to social learning dynamics on tree networks. Finally, we prove fundamental limits on the rate of information aggregation in tree networks via social learning, when votes are discrete.
