This study attempts to empirically investigate if value strategy and momentum strategy could be improved by using past financial data such as ROE and PER in the Korean stock market. The study observes that both strategies which are refined by the portfolios consisting of companies with higher ROE/PER ratio show higher positive excessive returns than the traditional value strategy and momentum strategy. The study discusses that the excessive returns could be due to investors' behavioral biases such as conservatism, anchoring, confirmation, and herding by using convergent approach based on psychology theory. The results are not consistent with the efficient market hypothesis insisting investors' rational behavior.

In this study, we investigate the effects of disclosure and high-quality audit on donations to charitable organizations in Korea. We find that the mandatory disclosure of financial information and high-quality audit is significantly and positively related to donations to charitable organizations. We also find that charitable organizations audited by Big 4 audit firms have greater likelihood to receive more donations, compared to those audited by non-Big 4 audit firms. Furthermore, we find that those positive associations are more pronounced for smaller charitable organizations. Collectively, those results imply that, as in the profit-making sector, disclosure and high-quality audit play a critical role in enhancing accountability and transparency of financial reporting and revenue for charitable organizations.

Competition among enterprises has been more intensified as one among supply chains in the rapidly changing environment. This study investigated the influence of the supply chain integration factors, such as integration of functions inside an enterprise, integration of suppliers, and integration of customers, on the internal and external visibility, and non-financial and financial performances of enterprises. To test these relationships, the survey was conducted on suppliers, manufacturers, and distributors in Korea which have been implementing SCM. Eighty-one questionnaires were collected and used for this study. The study results using the covariance structure analysis are showed as follows. First, the integration of suppliers had a significant influence on both the internal and the external visibility of enterprises, while the integration of functions inside an enterprise had a significant impact on only the internal visibility of enterprises, and the integration of customers on only the external visibility. Second, the internal and external visibility of enterprises had significant impacts on non-financial performance of enterprises. However, the internal and external visibility of enterprises didn't give any direct or indirect influence on the financial performance of enterprises.

This paper tests a correlation between degrees of operating leverage(DOL) and financial leverage(DFL). For an empirical analysis, this paper extracted information from financial statements of manufacturing companies listed in the Korea Stock Exchange. Data extend from 1990 to 2009. The DOL continued to increase until 1997, but decreased dramatically after the IMF financial crisis. However, the DOL has been at a higher level than companies of other countries such as USA and Japan. The DFL has been maintained at a much higher level, as expected. The empirical results indicate a positive correlation between the DOL and the DFL. To further investigate, we divide the whole sample into subgroups according to such management elements as asset size, IMF crisis. The results for sub-samples are different from those of whole sample. This indicates we need to incorporate specific managerial factors in order to correctly explain financial decision processes.

Real option thinking can provide a strategic agility, especially when IT managers consider ERP investment projects. Managing financial and IT risks is critical for the success of ERP investment projects. We examine whether Korean IT managers apply the real option thinking when considering ERP investment projects. On the basis of a survey data collection, we validate hypotheses based on existing literature in IT and finance. Notably, Korean IT managers consider only volatility among financial risk variables and two important IT risk variables, namely, requirement changes and continuous training costs.

We, in this study, tried to examine the influence of business environment, organization structure and information technology characteristics used on the performance of the information systems in Information and Communications Industries. The result shows that frequency of system usage and users' satisfaction are positively affected by the factors of business environment, organizational structure and information-technology. The user satisfaction of the system is affected by the frequency of system usage. Both financial performance and non-financial performance are affected by the frequency of the systems usage and user satisfaction of the system. With path analysis, we verified the overall model goodness-of-fit verified for the research model. The result shows that organization structureand technological factors are positively related to the frequency of usage and user satisfaction of the system, while the environmental factors are not. The frequency of system usage is not linked to both financial and non-financial performance. The user satisfaction of the system does not affected to the financial performance. In conclusion, the usage frequency and user satisfaction of the system are the moderating variables affecting business performances. These two variables are affected by the environment, organization structure and information technology. The Path analysis also supports the relationships among these variables.

불행하게도 우리 대학의 경우, 자원의 사용에 대한 정보의 공시가 적정수준으로 이루어진 적이 없다. 정보의 공시란 다수의 의사결정자들이 합리적 판단을 할 수 있도록 하는 기능을 수행하기 때문에 사회적으로 가치를 갖는 것이다. 여기에서 우리는 재정 개혁을 위한 출발점으로 재무정보의 신뢰성 있는 공시를 제안한다. 최고의 지성집단인 대학이 자원 사용에 대한 보고책임을 게을리 하면서 부족한 자원을 공급해달라고 사회에 요청하는 것은 어불성설이다. 겸허한 자세로 정직.성실한 보고를 한 후 부족 자원 공급을 요청하는 것이 순리다.

본 연구는 우리 나라에서 최근에 다수의 기업들이 실시하고 있는 주식분할(Stock split)이 투자자들에게 실시기업의 미래의 경영상태를 양호하게 보도록 하는 정보를 시장에 신호하는 도구가 되고 있는지 살펴보았으며, Fama-Fisher-Jensen-Roll의 연구처럼 그 정보가 주식분할기업의 향후 배당가능성을 의미하는지를 조사하였다. 만약 배당 가능성이 주식분할의 동기가 아니라면, 다른 동기가 있는지도 검증해 보았다. 연구결과는 우리 나라 시장에서 주식분할공시가 주가에 영향을 주는 것으로 나타났으며, 그 동기가 주식분할실시기업의 향후 배당가능성은 아니며, 오히려 주식분할을 통해 주가를 적정거래범위내에 거래될 수 있도록 유도하려는 의도가 그 동기가 된 것으로 볼 수 있다.
