The purpose of this study is to find the difference of status of youth overeducation and to analyze the impact on the wage between before and after the financial crisis.

In this study, we adapt the following method; first, we merge the 1996 and 2002 data from 『the Survey Report on the Wage structure』 with the 2003 data from 『the Occupational dictionary』 by occupation group. Second, we match the two wage data with the data from the Occupational dictionary. So that we could find the difference between the youth over educational status in 1996 and that in 2002. Third, we investigate the reason why the difference occur. Forth, we try to find the difference between the impact of the overeducation on the wage in 1996 and that in 2002.

The results are followings; First, the degree of overeducation in 2002 is more than in 1996. However, the financial crisis play the role to reduce the degree of overeducation. This means that if the financial crisis has not occurred, the degree of the overeducation in 2002 is much more than in 1996.

Second, the wage rate of overeducated worker is higher than that of required educated worker but these finding are reversed, so that the wage rate of overeducated worker is lower than that of the required educated worker. Such a finding means that even though the both wage rate of the overeducated and required educated worker are increased, the wage rate of the required educated worker is much more increased than that of overeducated worker after the financial crisis.
