대졸 청년층의 대학 재학 중 일 경험이 첫 일자리 직무만족도에 미치는 영향

Abstract

Objectives This study was conducted to verify the effect of in-school work experience on job satisfaction in the first job among college graduates and to explore how the purpose of work experience while in school and the rele-vance of the major affect job satisfaction in the first job.
 Methods To do this, causal forests were applied to the 2020 Graduates Occupational Mobility Survey (GOMS) to examine the average treatment effect of in-school work experience on the job satisfaction of the first employment. Additionally, heterogeneous treatment effects were explored based on personal backgrounds, col-lege factors, job preparation, and characteristics of the first job among college graduates. Furthermore, hier-archical regression analysis was applied to control for variables that were significant in the heterogeneous treat-ment effects and to verify the effects of the purpose of work experience and the relevance of the major on job sat-isfaction in the first job.
 Results First, the average treatment effect of work experience during college had a positive effect on job sat-isfaction in the first job. Second, the heterogeneous treatment effect of college location was significant, with some regions showing a decreasing effect of in-school work experience on job satisfaction in the first job. Third, livelihood type work experience has a negative effect on job satisfaction in the first job. Fourth, the relevance of work experience to the major had a positive effect on job satisfaction in the first job.
 Conclusions Based on the findings, implications and policy implications of the study were discussed.
