A large and growing literature spanning multiple fields has identified employee mobility as a critical influence on several important organizational outcomes. However, extant research on the topic is highly fragmented and lacks a unifying theoretical framework, impeding the development of a cumulative conceptually integrated body of research. We seek to remedy this situation by undertaking a review of research on employee mobility and its organizational impacts and casting it within a novel integrative conceptual framework. As a critical foundation for this framework, we highlight how the various organizational impacts of employee mobility are ultimately engendered by different dimensions of human and/or relational capital that are conveyed by mobile individuals. Building on this foundation, we describe how multilevel contextual factors-characterized as attributes of the employee, source and destination firms, and environmental conditions-may moderate the transfer and utilization of human and rela-
IntroductionOver the last two decades, a significant research literature has emerged about the interorganizational movement of personnel and its substantial individual-level, organizational, and societal impacts. Inquiry into this phenomenon has spanned diverse fields, including economics, human resource management (HRM), strategic management, and sociology. However, while each of these respective research streams has provided valuable insights into the antecedents and consequences of the interorganizational movements of talent, the result is a research literature on employee mobility that is highly fragmented and disorganized.Despite its lack of coherence, literature on employee mobility is of particular interest to strategy and management scholars because the interorganizational movement of personnel affects important organizational outcomes, such as innovation (e.g., Rao & Drazin, 2002;Song, Almeida, & Wu, 2003), learning (e.g., Singh & Agrawal, 2011), capability acquisition and divestiture (e.g., Agarwal, Echambadi, Franco, & Sarkar, 2004), market entry (Boeker, 1997), relationship management (e.g., Broschak, 2004;Carnahan & Somaya, 2013;Somaya, Williamson, & Lorinkova, 2008), and even firm failure (e.g., Phillips, 2002;Wezel, Cattani, & Pennings, 2006). Building on Arrow's observation that the "mobility of personnel among firms provides a way of spreading information" (1962: 615), both scholars and industry practitioners alike have recognized that successfully navigating the market for human resources (HR) can be an important driver of firm competitive advantage (Barney, 1991;Cappelli, 2000;Gardner, 2002;Michaels, Handfield-Jones, & Axelrod, 2001).Moreover, ongoing technological, societal, and economic changes are accelerating the tendency for employees to switch employers (Cappelli, 2000;Henderson & Bierman, 2009) and increasing the intensity with which firms compete over high caliber talent (Coff, 1997;Gardner, 2005). Additionally, employees have become increasingly strategic in managing their careers by buildi...
