Abstract : Classic literature in labor economics and economic sociology has documented how managerial careers are shaped by internal labor markets and organizational division of labor. Yet the last three decades have been marked by a dramatic increase in external hiring, proliferation of new forms of employment, and the emergence of career histories that span multiple employers, industries, and occupations. This means that our understanding of intra- and inter-firm mobility of managerial workers in modern labor markets might be incomplete. In my dissertation, I explore how managers move between jobs and assignments, how organizations make their choices in filling vacant positions, and how market intermediaries shape talent flows and individual careers. I focus on functional (occupational) dimension of managerial experience. I aim at demonstrating how experience in many vs. one (or few) functions influences career outcomes for middle managers in internal and external labor markets. I concentrate on two mechanisms by which spanning functional boundaries might shape one’s subsequent mobility: (1) skills acquisition and transferability and (2) career history as a signaling device. In the first chapter, I investigate how experience in multiple functions impacts transition into management and promotions from lower to higher management within a single organization, where information asymmetry about actual workers’ abilities is less pronounced and, therefore, signaling is less likely to play a role. This project contributes to the literature on managerial careers and studies of internal labor markets by highlighting the multi-dimensionality of managerial experience and demonstrating how horizontal mobility shapes vertical mobility in organizations. In the second chapter, I study whether functionally diverse or focused profiles are more appreciated in the mediated labor market for middle management jobs, where both learning and signaling mechanisms are likely to be at work. This setting allows me to introduce the effect of the relative candidate evaluation, i.e., the structure of the candidate pipeline. This project has important implications for the literature on managerial careers and studies of external labor markets by providing new contingency factors for understanding the effect of specialization on career outcomes. The third chapter is devoted to the macro patterns of managerial mobility and their connection to organizational design. I use a large sample of matched employee-employer data collected by the French National Statistical Institute to look at how managers with different career profiles are matched to organizations with different structures and moved to different parts of these organizations.
