How does the first job matter for an individual's career life in Japan?

Exploiting annual information on the work status of female workers from the Japanese Panel Survey of Consumers (JPSC), this paper examines how an individual's job status immediately after graduation, referred to as “first job,” matters for his/her future job career. Using the ratio of regular employees in the labor force in the year preceding an individual's graduation as an instrument for the first-job status (i.e., regular job or not), we confirm that even for women, whose retention rates are lower than those of men because of marriage and childbirth, individuals' first-job status has a significant effect on their job status in the future. We further find that the effect gradually declines over the years and effectively disappears around 10 years after graduation. Finally, we find that the first-job effect is reversible: no negative effect of failing to obtain a regular job at graduation is observed if an individual can secure regular employment within a reasonable time period after graduation.
