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.

The aim of this book is to study the links between urban economics and labor economics. Different models of urban labor economic theory are examined in the initial two parts of this book: first urban search-matching models (Part 1) and then urban efficiency wages (Part 2). In Part 3, we apply these models to analyze urban ghettos and their consequences for ethnic minorities in the labor market. Professor Zenou first provides different mechanisms for the so-called spatial mismatch hypothesis, which postulates that housing discrimination introduces a key frictional factor that prevents minorities from improving access to job opportunities by relocating their residences closer to jobs. He then explores social networks, which tend to be affected by spatial factors, as workers who are physically close to jobs can be socially far away from them. Based on these models, the author offers different policies aiming at fighting high unemployment rates experienced by ethnic minorities residing in segregated areas.
