이 논문에서는 졸업정원제가 대졸-고졸 간 임금격차에 미친 영향의 범위와 구조를 실증적으로 분석한다. 세대와 학력이 임금에 끼치는 구조에 대한 사전적 제약을 최소화하기 위하여 임금 결정모형에 세대와 학력 변수가 비모수적으로 들어가는 반모수적(semiparametric) 모형을 추정하였다. 실증분석 결과, 첫째 졸업정원제 세대(1962년생부터 1965년생까지)부터 대졸 공급이 급증하였지만 대졸 프리미엄은 세대간 시차를 두고 그 이후 세대부터 줄어들었다는 점, 둘째, 이러한 하락의 원인은 대졸 인력의 하향취업, 저숙련에서 대졸 프리미엄의 하락, 고졸의 숙련 프리미엄의 하락에 있다는 결론을 얻었다. 이 결과는 졸업정원제가 고임금 부문 보다는 저임금 부문에 크게 영향을 주었음을 시사한다. This paper empirically studies effects of the graduation quota system on wage differentials between college and high school graduates. We estimate a semiparamteric model that includes non parametric interaction terms of cohort and education. Results show that (1) the significant drops in college premium occurred with a lag and lasted for the younger generation, and (2) underemployment of college graduates, decreased. wage differentials of low-skilled jobs, and decreased skill premiums of high school graduates are the main causes of the drops in college premium. They suggest that the effects of the graduation quota system have centered around the low-waged workers.

Since the 2000s, the numbers of Ph. D’s has rapidly increasing but the increase of jobs in public sector is stagnating. The expansion of the employment of Ph. D’s in private sector is a necessary task not only to alleviate supply-demand mismatch, but also to respond to the growing social demand for advanced science and engineering knowledge as it progresses into knowledge-based society. In order to expand the employment, it is needed an in-depth analysis of the characteristics of R&D activity, role, and career-path of Ph. D’s in private sector. However, only limited research has been conducted on the subject, and systematic statistics on the career of Ph. D’s are still in the beginning stage. In this study, we have studied characteristics of science and engineering doctoral degree holders working at private sector through existing statistics and case study. Supply-side has been studied based on the survey conducted by KRIVET, and demand-side based on the R&D and employment statistics conducted by several institutions, such as STEPI, KISTEP, and KOSTAT. Linking the two analysis, we have observed the deterioration of labor market conditions of Ph. D’s, and gradual differentiation of characteristics of Ph. D’s according to the type of universities. In private sector, as a consumer and workplace of Ph. D’s, there is not a small gap between the demand of company and capabilities of Ph. D’s. Based on the results, we have proposed policy direction and tasks for training and utilization of Ph. D’s.
