본 논문에서는 패널회귀모형에서 회귀계수의 일반최소제곱추정량과 가중최소제곱추정량의 설계기반 성질을 살펴보았다. 복합표본이 주어진 경우에 두 추정량의 설계편향을 구하여 가중최소제곱추정량의 설계편향의 크기가 더 작음을 보였다. 또한 한국복지패널 데이터를 대상으로 모의실험을 실시하여 다음의 결과를 얻었다. 첫째, 일반최소제곱추정치의 상대편향이 가중최소제곱추정치의 상대편향보다 약 2배 정도 크게 나타났고 일반최소제곱추정치의 편향비가 더 크게 나타났다. 그리고 표본수가 증가하면 일반최소제곱 추정치의 상대편향은 완만하게 줄어든 반면 가중최소제곱추정치의 상대편향은 급속도로 줄어들었다. 둘째, 표본수가 증가하면 일반초소제곱추정치와 가중최소제곱추정치의 분산과 평균제곱오차는 모두 줄어들였다. 그러나 평균제곱오차에서 차지하는 편향제곱의 비율은 표본수가 증가할 때 일반최소제곱추정치에서는 증가하는 반면 가중최소제곱추정치에서는 감소하는 경향이 나타났다. 마지막으로 거의 모든 경우에 일반최소제곱추정치의 분산이 가중최소제곱추정치의 분산보다 작게 나타났다. 그리고 많은 경우에 일반최소제곱추정치의 평균제곱오차가 가중최소제곱추정치의 평균제곱오차보다 작게 나타났다. 그러나 표본수가 증가할수록 일반최소제곱추정치의 평균제곱오차가 가중최소제곱추정치의 평균제곱오차보다 커지는 경우가 늘어났다.

In this study, the current state of management efficiency of ocean carriers in Korea and the factors affecting them were analyzed. The purpose of this research is to enhance global competitiveness of ocean carriers by presenting suggestions that can improve management efficiency based on the analysis results. The measurement of management efficiency was made using the DEA model. The results of testing the adequacy of the input and output variables used are as follows. Appropriate inputs are total assets, cost of goods sold, charter expenses, sales and general management expenses, and interest expenses. Appropriate variables are sales, operating income, and operating cash flow. According to the analysis results of the DEA model by these variables, inefficient carriers (78%) are nearly four times more than efficient carriers(22%). However, container carriers have the most improved management efficiency compared to 2016 and 2017. According to the panel regression analysis, the charter rate has the greatest negative impact on efficiency (CRS), and the debt rate has a significant negative impact. Thus, it appears that reducing the charter size and the debt-to-sale rate facilitate improvement of the management efficiency of ocean carriers. Additionally, the pre-sales tax return rate, value added rate, total asset turnover rate, and the scale variable and interest coverage rate have a positive (+) effect. Thus ocean carriers should restore their global competitiveness by improving management efficiency by securing stable cargoes increasing sales profitability from the cost management perspective, increasing productivity, and enhancing the efficiency of their total assets through efficient fleet management.

본고에서는 OECD 회원국(2018년 현재 총 36개국) 중 29개국을 대상으로 상용직·임시직 고용비중 변화가 노동생산성에 미치는 영향을 실증 분석하였다. 이 때 자영업자도 함께 고려함으로써 상용직 및 임시직 대비 노동생산성을 비교하였다. 구체적으로는 1990-2015년 동안 OECD 29개국의 국가별 불균형(unbalanced) 패널자료를 이용하여 통상최소자승법(OLS), 고정효과(fixed effect) 분석, 일반화된 적률법(이하 GMM), 동태적 패널 GMM 등 다양한 방법으로 고용형태 변화가 노동생산성에 미치는 영향을 추정하였다. 분석 결과를 보면, 각 추정 방법에 따라 약간 차이는 있으나 상용직 비중 증가가 노동생산성 증대에 미치는 영향이 가장 높았으며 그 다음이 자영업, 임시직 순으로 나타났다. 특히 임시직 근로자 비중이 노동생산성에 미치는 영향은 상용직에 비해 상당 폭 낮은 것으로 추정되었다. 이러한 결과는 노동시장 이중구조가 심화되면 노동생산성에 부정적 영향을 미칠 가능성이 있음을 시사한다.

Objectives: This study aimed to analyze the Korean medical utilization and Korean medical expenses by characteristics of multicultural family members to investigate whether it affects Korean medical utilization. Methods: This study utilized The Korea Health Panel data in 2018, with 238 final participants. We performed a t-test and ANOVA on the difference between Korean medical utilization and Korean medical expenses according to Anderson's Model of Health Service Utilization variables. Logistic regression analysis and generalized linear model analysis were conducted to analyze Korean medical utilization factors. Results: The Korean Medical utilization was 12.61% among the multicultural family members. As a result of regression analysis, the female had high Korean medical utilization(p=.008), and rural area residents had low utilization(p=.017). Korean medical expenses were high when they were female or married. Including the utilization of western medical services by outpatients, Korean medical expenses were high when they were female or outpatients who received western medical services. Conclusions: As a result of this study, the factors influencing Korean medical utilization were gender and residence area. There were differences in Korean medical expenses depending on western medical services use or gender. Therefore, it is necessary to use these factors to expand the Korean Medical utilization by multicultural family members, and research of the Korean medical utilization by disease is needed.

Purpose: This study aims to investigate the cross-sectional association of company size and self-rated health using representative data on Korean workers. Methods: We used the data from 2,884 wage workers collected by Korean Labor and Income Panel Study (17th). The association between company size and self-rated health was analyzed using logistic regression with covariates including demographic characteristics, work environment, job satisfaction, and health-related behaviors. Resulst: Odds ratio (OR) for better health status among workers in large-sized company was 1.351 (CI. 1.054~1.731), compared to workers in small-sized company. We performed three separate models stratified by firm size (small, medium, and large companies). Occupation variables showed different effect on health depending on firm sizes. OR for better health of white-color job (referred to blue-color job) was 1.693 in medium-sized company model but it was 0.615 in large company model. OR for better health of the workers working shift work showed 0.606 in large company model but it was not significant in small and medium company models. Conclusion: We found that small-sized company workers have significantly poor self-rated health compared to large-sized firm workers. This study revealed that there exist differences among health related factors depending on firm sizes.
