This volume collects papers from Hugo Sonnenschein's students. It aims to demonstrate his tremendous impact as an advisor. The papers span decades and present some of the most important articles in microeconomic theory. Each paper is accompanied with a preface by the student providing background on the paper and indicating Hugo's influence on its genesis. The papers all lie in microeconomic theory, and moreover all make fundamental contributions to the foundations of the theory.

The organization of individuals into networks and groups is of fundamental importance in many social and economic interactions. Examples range from networks of personal contacts used to obtain information about job opportunities to the formation of trading partnerships, alliances, cartels, and federations. Much of our understanding of how and why such networks and groups form, and the precise way in which the network or groups structure affects outcomes of social and economic interaction, is relatively new. This volume collects some of the central papers in this recent literature, which have made important progress on this topic.

This comprehensive two-volume set brings together important contributions providing fundamental economic analyses of social networks and the central roles they play in many facets of our lives. The first volume consists of classic articles that model network formation and games on networks, as well as those on the identification of peer effects from an econometric viewpoint. The second volume provides empirical analyses of network effects on labor, education, development, crime and industrial organization, as well as some laboratory and field experiments. This set of indispensable papers, with an original introduction by the editors, will prove an essential tool to researchers, scholars and practitioners involved in this field.

When Murat Sertel asked us whether we would be interested in organizing a special issue of the Review of Economic Design on the formation of networks and groups, we were happy to accept because of the growing research on this important topic. We were also pleasantly surprised at the response to our request for submissions to the special issue, receiving a much larger number of sub missions than we had anticipated. In the end we were able to put together two special issues of insightful papers on this topic. Given the growing interest in this topic, we also decided (with encouragement from Murat) to combine the special issues in the form of a book for wider dissemination. However, once we had decided to edit the book, it was natural to move beyond the special issue to include at least some of the papers that have been influential in the literature on the formation of networks. These papers were published in other journals, and we are very grateful to the authors as well as the journals for permission to include these papers in the book."

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.

How do economists understand and measure normal social phenomena?

Identifying economic strains in activities such as learning, group formation, discrimination, and peer dynamics requires sophisticated data and tools as well as a grasp of prior scholarship. In this volume leading economists provide an authoritative summary of social choice economics, from norms and conventions to the exchange of discrete resources. Including both theoretical and empirical perspectives, their work provides the basis for models that can offer new insights in applied economic analyses.
Reviews the recent approaches that enable economists to separate influences of culture from those caused by economic and institutional environments
Explores the recent willingness among economists to consider new arguments in the utility function
Presumes that these investigations can eventually be translated into policies

It's not what you know, it's who you know. Or so the adage goes. Professor Matthew Jackson, world-leading researcher into social and economic networks, shows us why this is far truer than we'd like to believe. Based on his ground-breaking research, The Human Network reveals how our relationships in school, university, work and society have extraordinary implications throughout our lives and demonstrates that by understanding and taking advantage of these networks, we can boost our happiness, success and influence. But there are also wider lessons to be learnt. Drawing on concepts from economics, mathematics, sociology, and anthropology, Jackson reveals how the science of networks gives us a bold new framework to understand human interaction writ large - from banking crashes and viral marketing to racism and the spread of disease. Filled with counter-intuitive ideas that will enliven any dinner party - e.g. how can our popularity in school affect us for the rest of our lives? - The Human Network is a "big ideas" book that no one can afford to miss.

How can economists define social preferences and interactions?

Culture, familial beliefs, religion, and other sources contain the origins of social preferences. Those preferences--the desire for social status, for instance, or the disinclination to receive financial support--often accompany predictable economic outcomes. Through the use of new economic data and tools, our contributors survey an array of social interactions and decisions that typify homo economicus. Their work brings order to the sometimes conflicting claims that countries, environments, beliefs, and other influences make on our economic decisions.
