The purpose of this study is to estimate the effects of working while in college on the labor
market transitions after graduation. In particular, among the various types of working in college, we
classify student loans and working for living as livelihood type labor to study the effects of working
while in college in-depth. This study uses data from the Graduates Occupational Mobility
Survey(GOMS) and applies the Propensity Score Matching(PSM) in order to control heterogeneous
nature between research objects. Analysis shows that 70 percent of the whole research students
experiences working while in college and 27 percent of them is working for student loans or living
expenses.
In case of livelihood type labor, working while in college affects one’s college life and raises the
probability of lower grades. Also, it is one of the reasons which makes the period of attendance at
college longer. Students who work while in college reduce the job search period to recover the
extended period of attendance at college; moreover, short job search period makes students have a
strong possibility that they enter into secondary labor market and get lower wages.
Therefore, this study explains problems about livelihood type labor while in college and suggests
political alternatives for these problems.
