Abstract
In this paper, we study determinants of the total number of job experience and duration to first job in university using by using graduates occupational mobility survey (GOMS 2009). We set the four models such as Poisson regression model, zero-inflated Poisson model, negative binomial model and zero-inflated negative binomial model. Zero-inflated negative binomial regression model was selected as the optimal model, the main result of the impact on the number of job experience of college are as follows. First, the number of jobs, male experienced in college was small in comparison to female. Second, the number of jobs experience for university is more than the one of college. Third, there is job number one experience in college tend to have increasingly lower GPA (grade point average) up. Also we use Cox's proportional hazard model to analysis duration to first job. The main result of the impact on the duration to first job are as follows. First, male are more likely than female to escape into employment. Second, the greater the number of job experience in college, the higher GPA, as the increase in the number of licenses was higher chance of escape as first job after graduation.
