  • The early studies indicated that the firm with monopoly power is likely to engage in X-inefficiency such as a managerial slack. The reflection of the X-inefficiency theory has led to the issue that the public sector may be more inefficient than the private sector. In Korea like other many countries the electricity gas water service which can be considered as natural monopoly have been provided mostly by the public sector. In order to provide the empirical evidence to the argument that the public sector may be more inefficient than the private sector this paper estimated the four types of Solow residual which is called the total factor productivity in the electricity gas water service industry with the associated empirical model and compared its productivity with one in the manufacturing industry. The empirical results do not support the argument that the public sector may be more inefficient or less productive than the private sector.

  • Purpose: The purpose of the study is to analyze the characteristics of emotional intelligence and the variables related to emotional intelligence in a comprehensive manner. In addition, the study intends to present research trends and future research directions of emotional intelligence in a Korean context by analyzing the effects of emotional intelligence and its mechanisms. Research Design, Data, and Methodology: 77 KCI listed studies were selected for the analysis, and the research perspective of emotional intelligence, measurement instruments, empirical research and research methods were analyzed. In addition, research directions were suggested based on the analysis results. Results: The results of the analysis were as follows: First, previous researchers used the ability model of emotional intelligence the most. Second, Previous studies tended to focus on behavioral factors as dependent variables affected by emotional intelligence, in addition to attitudes, affection. Third, there were few studies on the antecedents of emotional intelligence, however, most studies dealt with the consequences of emotional intelligence. Fourth, few studies dealt with moderators between emotional intelligence and dependent variables. Fifth, on the research type, most studies were quantitative studies, however, a few of them were qualitative studies (Literature review, in-depth interview). Sixth, with regard to the analysis level, almost all studies were conducted on the individual level of emotional intelligence, and most studies featured a cross-sectional research design (longitudinal research design was rare). Conclusion: First, from the perspective of emotional intelligence, additional research should be focused on not only the ability model of emotional intelligence but also on the trait model or the mixed model in the future. Second, since emotional intelligence is a multidimensional construct, it is necessary to study the profile of emotional intelligence by employing people-centered as well as variable-centered methods. Third, with regard to empirical studies, additional research is needed with respect to not only the emotional intelligence of the subordinate, but also the emotional intelligence of the supervisor (leader) and the emotional intelligence of the group. Fourth, it is necessary to actively utilize not only cross-sectional design but also longitudinal design, and qualitative research and meta-analysis methods should also be adopted.

  • 본 연구의 목적은 한국노년학회가 1980년도부터 발행한 "한국노년학"에 실린 심리학 관련 연구를 살펴보는 것이다. 지난 30년 간 총 130편의 심리학 관련 논문이 출판되었다. 1980년에는 총 19편이 출판되었는데, 이 중 14편이 경험적인 연구이고 나머지 5편이 문헌고찰이다. 1990년에는 총 51편이 실렸으며, 이 중 49편이 경험적 연구이고 2편이 문헌고찰이다. 2000년대에는 총 60편이 나왔으며, 경험적인 연구가 56편으로 압도적으로 많았고, 문헌고찰 연구나 이론적 연구는 4편에 불과했다. 주로 다룬 주제는 노인의 정신건강, 삶의 만족 및 여가, 부모부양 및 가족관계, 노년기 인지적 변화 그리고 노년기 일반 등이다. 연대별 연구추이를 살펴본 후, 주제별로 관련 연구를 고찰했다. 마지막으로, 기존 연구의 한계점을 지적하고 앞으로의 연구를 위한 제언을 제시했다.

  • We review the literature on the effectiveness of capital controls and macroprudential measures. First, we explain the purposes and examples of capital controls and macroprudential policies. We then analyze various theoretical models and empirical findings from prior studies that investigate the effectiveness of each instrument. Moreover, we review several studies that directly compare the two instruments and discuss whether policymakers should implement capital controls or macroprudential measures to overcome financial crises. Finally, based on a discussion of the findings of previous studies, we suggest several possible avenues for future research.

  • Recent trends in business are characterized by recognition of the importance of knowledge assets. Especially, this phenomenon is receiving more momentum as our society goes digital rapidly. The concept of Knowledge Management has long been used as an effective way of restructuring the management process of a firm. In literature regarding knowledge management, a number of successful cases were reported, where knowledge-based management activities could dramatically enhance a firm's strategic performance for years. However, there exists very little research investigating the effect of knowledge management on corporate competitiveness. Researchers as well as practitioners need more rigorous results about such issues, especially how much the knowledge management strategic initiatives may have an influence on the firm's competitiveness. In this sense, we need an empirical study adopting statistical approaches due to the existence of abundant knowledge management case studies. To fill this research void, this study proposes a research model testing whether knowledge management activities could improve corporate competitiveness. We collected 321 valid questionnaires from participants in knowledge management activities in the tourism industry and applied a structural equation model. Empirical results showed that knowledge management activities have a positive impact on knowledge management efficiency and finally corporate competitiveness. We hope that this study will shed light on further rigorous studies considering tourism industry as a major strategic activity.

  • This study is an empirical research in order to clarify whether or not the correlation between the satisfaction of users that is the performance measurement factor and the following three:(1) the attitude of users as an individual characteristic, (2) the supports of organization as an organizational characteristic, (3) the routine degree of jobs as an job characteristic, is the same as the previous study results. In addition, another empirical research was done to make clear how organizational supports and routine degree change the attitude and satisfaction of users. This study put a particular emphasis on the moderating effect because the study of this issue has not been done in any previous research. 38 corporations, whose computerization has already been made to some extent and who are listed on the stock exchange market as a leader group, was selected for research, given some hypotheses on the basis of theoretical studies. As results of this empirical study, first, the supports of organization and the routine degree of jobs changed the attitude of users, which was the same as the previous studies. Moreover, the supports of organization, the routine degree of jobs and the attitude of users had an influence on the satisfaction of users. Second, in respect of the correlation between the attitude of users and the satisfaction of users, the routine degree of jobs showed a moderating effect, but the organization supports did not show any moderating effect.
