What enables some organizations to routinely perform better than others? Conversely, what makes some firms consistently perform worse than their competitors? Within a single corporation, what enables some teams or individual firm members to outperform their counterparts? Through the concept of social capital, this book addresses these questions by studying the effects of relationship networks on the ability of corporate players to attain their professional goals. The idea of social capital has become one of the premier approaches to studying networks in the context of organizations but the literature still lacks a conceptual paradigm that connects the various approaches, definitions and measure of social capital into an integrated analytical model. By explicitly connecting social networks to the goals of corporate players, this book provides a unifying framework to the study of social capital in an organizational context. In this volume social capital is defined as the resources that accrue to an actor through his or her social relationships and that aid in the attainment of goals. The book introduces the notion of social liability as a framework to analyze the negative effects social networks can have on the attainment of goals by firms and/or their members. It thus presents a way to tie together findings and approaches in the literature by explicitly addressing the distinction between networks and outcomes, the distinction between networks at the level of firms and networks at the level of individuals, and the distinction between positive outcomes of social structure (social capital) and negative outcomes (social liability). The book’s contributors are 46 acclaimed scholars from around the world with backgrounds in management, business and sociology.
