Job mobility and wage trajectories for men and women in the United States

Young American workers typically change employers many times in the course of establishing their careers. This article examines the consequences of this mobility for wage inequalities between and among men and women. Using multilevel modeling and data from the 1979 to 2002 waves of the National Longitudinal Survey of Youth 1979 (NLSY79), I disentangle the various ways in which mobility shapes the trajectories of wage growth. Findings caution against accepting the adequacy of prevalent economic models of mobility-models that tend to isolate individual workers' moves from broader patterns of work history and that treat mobility as a decontextualized individual choice. Although workers who frequently switch employers generally end up earning less than their more-stable counterparts, the type, timing, and relative level of changes strongly affect the ultimate wage differential. Differences in the degree,of men and women labor-force attachment and family circumstances are also influential. Workers who are less attached to the labor force benefit less from changing employers, and women who are married or have children also tend to experience less-favorable mobility-wage outcomes.
