Studies of gender differences in the returns to job mobility have yielded conflicting results. We examine whether there are gender differences in mobility patterns or in the returns to different types of mobility. Our results, based on the National Longitudinal Survey of Youth, imply that there are gender differences in mobility patterns, but there are not gender differences in the wage growth associated with different types of mobility. Therefore, it appears that empirical estimates of the gender differences in the returns to job mobility may be misleading if they do not consider the cause of separation.
