This study examines the job changes of the youth university graduates in Korea. The pattern of job changes get observed in the Unemployment Insurance Database. This data enables us tracing all job changes in the labor market. The average number of job youth graduates have for four years from graduate is 1.68. The more jobs youth have, the longer total tenure youth have. Youth are much more likely to change careers to different occupation or industry. They move usually into upper occupations but small establishments. They enhance the level of wage through job changes. The science and engineering graduates are more likely to change jobs than the humanity and social science graduates. The higher the level of wage they get is, the lower the probability of their job change is. Those who have good scores in Scholastic Aptitude Test are less likely to change job.

This study demonstrates the gender difference in the factors that affect job changes and the resulting wage changes in the recent Korean labor market. By using the KEAPS (2003-2007), we found that male workers uniquely tend to stay longer at their current jobs when they have families to support. After controlling self-selection bias, we also found that wage changes resulting from switching jobs differ between male and female workers during this studied period.

We construct a unique panel data by using Korean Economically Active Population Survey (KEAPS) from 2003 to 2007 to estimate the returns to different types of job mobility among men. By adopting Mincer(1986)'s method, we estimate the wage change to job mobility after controlling the sample selection bias. There are four different types of job mobility that are concerned in the study: (1) voluntary job-to-job changes without experiencing unemployment, (2) voluntary job changes with experiencing unemployment, (3) involuntary job changes due to layoffs, and (4) involuntary job changes due to discharges. Our findings indicate that Korean men who changed jobs without experiencing unemployment realized wage gains of 7% while those who changed jobs through unemployment period lost 10% of their wages. Among those who changed jobs involuntarily and went through unemployment, the workers who discharged from the previous jobs realized substantially greater wage loss.

First, The flow into and out of unemployment has been increasing considerably too since the late 1997. Moreover, about half of job changes involve career changes associated with industrial and occupational changes which workers work for. Workers who switch industries and occupations significantly suffer greater wage losses than observed similar workers who find new jobs in their pre-turnover industry or occupation. These findings imply that labor mobility is more likely to cause losses in accumulated skill of workers. Second, this study compared the wage return to past training when a worker remains with an employer with the wage return to past training when a worker moves to a new employer. Surprisingly, training provided by previous employers has significantly positive wage effect. These findings that the skill acquired by employer- provided training is transferable across some firms. Third, this study finds that the likelihood of sectoral mobility decreases with training received in the current industry. It gives an evidence of the industry- specific training. Based on these findings, this paper suggest the way of dividing the costs of benefits of training among employers within their sector to prevent under-investment in training.

This article examines the reasons for the observed discrepancy between worker's actual and required levels of schooling and the resulting economic effects in wage and labor mobility using KRIVET's Graduates Economic Activities Survey in 2005. Overeducated workers in Korea are estimated to be 10.1%-20.7% among junior college graduates and 18.8% among university graduates for their first job according to job analysis method and worker's self-assessment method each. The effects of school quality-measured by the student/teacher ratio, school building area/student ratio-on the overeducation of their graduates are found to be mostly insignificant not only junior colleges but also universities. This founding implies that the increase of education investment from schools does not acquire any recognition from the labor market. Also, the effects of overeducation and school quality on wages are found to be insignificant and job mobility has little effects on improving overeducated workers' job match.

This paper examines the impact of internal migration on wage growth among college graduates using Propensity Score Matching methods. We define migration as moving between Seoul Metropolitan Area (SMA) and non-SMA based on the locations of graduates' first and second jobs. We also take the direction of migration into account for examining the wage premium in SMA. In order to estimate the impact of migration on wage growth, we use the Graduate Occupational Mobility Survey (2010GOMS) coupled with other supplementary data such as College Scholastic Ability Test score and local characteristic variables. The results reveals that graduates moving from SMA to non-SMA do not experience significant wage growth. However, we find that graduates moving from non-SMA to SMA experience an increase in their monthly wage about 170,000~186,000 KRW on average (9.5~10.3% of their monthly wage on the first job).

This study investigates how the job satisfaction of the recipients with working ability is transformed into employment under the recent trends. The objects of this research are 15-19 years old. I used the data of YP2007. This survey were analyzed F-test by using SPSS PC win 12.0. This result maintain the importance about the policy of the recipients with working ability : (1) its bridging gaps between theory and reality, (2) focus on the Job satisfaction of the recipients with working ability, (3) developing new recipients with working ability education program, (4) elaborating the study methods. In this paper I describe one line of research focused on the job satisfaction of the recipients with working ability in view of their professional life as it is currently developed and expressed. This study also requires further studies and this study will be supplemented.

본 연구는 사슴의 조기 임신진단기법을 개발하기 위해 엘크 61두를 발정동기화 처리하고 인공수정하여 수정 후 20~24일에 38두의 혈액을 채취하여 혈청을 분리한 후 혈중 progesterone(P$_4$) 농도를 분석하였다. 혈중 P$_4$ 농도의 분석은 Walac Delpia 123(Delpia Co, Holland)을 이용하여 progesterone kit(Delpia, Co. 미국)로 분석하였으며, 임신진단의 정확도를 비교하기 위하여 수정 후 60일령에 직장검사와 초음파진단을 실시하였다.Table 1은 음파진단, 직장검사 및 P$_4$분석에 의한 임신진단 결과를 나타내었다. 진단방법에 따른 수태율은 초음파진단 72.1%, 직장검사 60.7%, P$_4$ 농도분석 68.9%, 초음파진단과 직장검사에서 동시 임신으로 판정된 것은 57.4%를 각각 나타내었다. 이상의 결과로 보아 사슴은 임신초기에 태아사멸이 많이 발생하는 것으로 추정되며, 임신진단기법 개발을 위해서는 지속적인 연구가 추진되어야 할 것으로 사료된다.

This study examines the job changes and the coincidence of job and major In the case of the youth, science and engineering graduates in Korea. The pattern of job changes and the coincidence of job and major get observed in the Unemployment Insurance Database and the Graduate List. This data enables us tracing all job changes in the labor market, and analysing the coincidence of job and major. The average rate of coincidence is not so high, the rate at first job is roughly one third. The youth with coincidence of job and major have earned less income than the youth without coincidence of job and major. But this result is impressive in the lower wage earners, any differences in regard to coincidence is not found in the upper wage earners. The probability of the coincidence of job and major is higher in case of the high wage and the high study attainments. The results suggests that the problem of the science and engineering graduates should be concentrated only on the lower manpower in the scientist and engineer jobs. Korean government have to lessen the number of entry into the science and engineering college and enlarge the number of entry into the science and engineering graduate school. Korean government have to prepare the system that aids establishment where the employee with coincidence of job and major earns more income.

This study analyzes the difference of search efforts and labor market performance between employed searchers and unemployed searchers, using GOMS(Graduates Occupational Mobility Survey) data collected by Korea Employment Information Service. The results show that unemployed searchers concentrated on the job search more actively, and their reservation wage decreased more rapidly than that of employed searchers. Therefore, considering only new jobs, the probability of employment was lower and the wage was higher for employed searchers than for unemployed searchers. However, both the employment probability and the wage were higher for the employed searchers, if analyzing all jobs including existing jobs of employed searchers. The results of this study imply that the employed search may be more effective strategy than the unemployed search.
