The purpose of this study is to empirically analyze the relationship between college graduates’ social capital and their employment/income in the labor market. For the purpose, this study utilized the Logit model, Pooled-ols, and multiple Panel regression models exploiting KEEP data of year 2013-2015, which provided comprehensive information of individual college graduates in the Republic of Korea. Our results first showed that college graduates’ social capital is positively related to their employments. To be specific, even though the participation on the unofficial organization is positively related to the status of employment, the participation on the official organization is negatively related to the success of employment. Secondly, this study also found that there was no statistically significant relationship b/w individual graduates’ social capital and their monthly income. On the other hand, college graduates’ human capital was closely related to the amount of monthly income of the employees. Based on the results of this study, we recommended some implications for relieving the importance and effect of college graduates’ social capital in an aspect of labor market.
