본 논문은 정년연장(근로기간 연장)의 경제효과를 분석한다. 근로기간 연장으로 인해 저축이 감소하여 자본투입이 하락할 경우, 근로자의 생애소득과 후생이 오히려 하락할 수도 있는 것으로 분석되었다. 그러나 자본이동에 대해 개방된 경제에서는 자본 유출입을 통해 생산요소의 가격 변화가 최소화되므로 근로자의 생애소득과 후생이 향상될 가능성이 높은 것으로 분석되었다. 따라서 후자의 경우에는 기존 근로자의 후생을 유지하면서도 추가적인 노동수요 확대를 모색할 수 있어 정년연장이 청년층 실업 완화에도 기여할 수 있을 것으로 판단된다.

Healthy worker effect (HWE) refers to the consistent tendency for actively employed individuals to have a more favorable mortality experience than the population at large. Although HWE has been well known since the 1970s, only a few studies in occupational epidemiology have attempted to fully define and evaluate HWE. HWE can be separated into effects on the initial hiring into the workforce (healthy worker hire effect) and those on continuing employment (healthy worker survival effect). In this review, we summarize the methods for minimizingor adjusting for the healthy worker effect available in occupational epidemiology. It is noteworthy that healthy worker survival effect appears complicated, considering that employment status plays simultaneous roles as a counfounding variable and intermediate variable, whereas healthy worker hire effect may be adjusted by incorporating health status at baseline into the statistical model. In addition, two retrospective cohort studies for workers in the semiconductor industry and Vietnam veterans in Korea, respectively, were introduced, and their results were explained in terms of healthy worker effect.

Objective: The purpose of this study is to explore daycare-center director's perceptons of recruitment and to understand how hire beginning teachers. Methods: One hundred twenty-five directors of daycare-centers in Seoul, Incheon, and Gyeonggi-do Province answered a questionnaire that was developed by researchers. The results were analyzed by frequency analysis, descriptive statistics and multiple response analysis through SPSS 18.0. Furthermore, 17 of the directors that participated in the study were given individual interviews by qualitative methods for research. Results: First, 56.8% of the directors felt difficulty to employ beginning teachers because of 'lack of information about them' and 'uncertainty of practice capability.' On the other hand, other directors of daycare-centers said that they hire them for 'high acceptance' and 'operational efficiency of the daycare-center.' Second, the main way to recruit teachers for daycare-centers is open recruitment, and through recommendations of acquaintances or through colleges in relevant fields. Professional talent and personal characteristics were important selection criteria for recruitment, and daycare-center directors used interviews, résumés, cover-letters, and demo classes for the hiring process. Primarily, most directors select candidates through résumés and cover-letters, and the final selection is completed by conducting interviews. Conclusion/Implications: In conclusion, this study can be useful to prepare beginning teachers for employment and for educating applicants.

IT outsourcing providers has been expanded from a single functional system to the entire IT service to gain sustainable competitiveness. This new trend of IT outsourcing need outsourcing management capability based on a firm's core capacity. Hiring external IT service providers to manage part or all of its information-related services helps a firm focus on its core business and provides better services to its clients, thus obtaining sustainable competitive advantage. This research investigates the major factors that determine the level of a particular firm's success at IT outsourcing. Based on process innovation and core-competency theories, we identify three significant components of a firm's IT outsourcing management method (ITOMM): level of core-competency-based management, maturity of outsourced tasks, and maturity of outsourcing management. Comprehensive data collection was conducted through an outsourcing association. The survey data were analyzed using a structural analysis method. Maturity of outsourced tasks and maturity of outsourcing management were found to affect project performance directly, while level of core-competency-based management only indirectly impacted project performance through its positive impact on the other two ITOMM components.

The study investigates the association between CEO education and firm performance with a sample of 85 nonfinancial firms listed on the Saudi stock exchange during 2018 applying ordinary least squares method. CEO education is defined by three variables, the level of education, if the degree-granting institution is domestic or foreign, and if the highest degree is in management or other fields of study. Financial performance is measured by return on assets and return on equity. Firm size, age, liquidity and growth are introduced as control variables. The study shows that 58 CEOs of the firms studied are graduates, 38 have obtained their degree from a domestic institution and 44 have a management degree. Graduate CEOs are found to enhance performance. Graduating from a domestic institution influences performance positively. Management degree of CEO does not seem to impact performance. Firm size, liquidity and growth are positively associated with performance. Firm age does not explain performance differences of firms. Results are robust to performance measures. The findings of the study suggest that firms can benefit from a CEO hiring policy that emphasizes on the minimum qualification set as graduation or higher, education from a domestic institution and no undue weight on management qualification.
