This book provides an overview and synthesis of models and techniques for analyzing
social and economic networks. This is meant to serve both as a resource for researchers
and a text on the subject for graduate students. The focus is primarily on the modeling
of and theory behind the structure, formation, and implications of social networks. Sta-
tistical and experimental analyses of networks are also discussed throughout, especially
when they help set the stage for issues to be investigated. The main emphasis is on
providing a foundation for analyzing and understanding social and economic networks.
