Abstract
In this paper, we analyzed characteristic variables of college graduates affecting job match. In general, job match contain two complex pieces of information about employment status of individual and job match size. We used the Heckman’s sample selection models utilizing the data of 「2014 Graduates Occupational Mobility Survey」conducted by Korea Employment Information Service. The main results are summarized as follows. First, Heckman’s sample selection model is statistically significant. Second, male is significantly higher in probability of employment and significant lower in the size of job matching than female. As age increases, the probability of employment is higher and the size of job matching is higher. Finally, as the grade point average increases and the number of licenses increased, the probability of employment tends to increase, but the size of job matching tends to decrease.
