This paper examines the processes of job mobility and wage growth among young men, tracking their careers over up to 15 years using the Longitudinal Employee-Employer Data (LEED). The study finds that young workers initially exhibit weak attachment to the labor force and specific employers, with a typical worker holding seven employers in the first decade of their career. Wage growth plays a crucial role in this transition to stable employment, with wage gains at job changes accounting for about one-third of early-career wage growth. The paper also models mobility decisions, suggesting that job-specific wages are a key determinant of mobility, with larger wage gains at transitions leading to more stable employment. The findings highlight the importance of job shopping in the early career development of young workers, despite the apparent haphazard nature of these transitions.This paper examines the processes of job mobility and wage growth among young men, tracking their careers over up to 15 years using the Longitudinal Employee-Employer Data (LEED).
