In this study, we investigated the market long-term performance of stock splits by using the Korean Stock Market data from 1998 through 2002. We measured the performance by the event-time portfolio approach with the buy-and-hold abnormal return(BHAR) and the cumulative average abnormal return(CAAR). Also, the calendar-time portfolio approach with one-factor and three factor model were used for avoiding the misspecification model problem. The first of main results in this study was that the stock splits had significantly positive abnormal returns around the month of the stock splits announcements. However, the period BHAR and CAAR after the announcement month were significantly negative. This negative long-term abnormal returns were confirmed by the calendar-time portfolio approach. The results suggested that the abnormal return followed by the stock splits seemed to be positive in the short-term period. Second, there was no the difference of the long term performance between the high and the low split ratios. The operating income performance in the periods followed by the stock splits announcements grew worse. Therefore, the signalling effects, the managers of the firm under considering the stock splits would make use of splits as a form of signals for the upward changes in the cash flow or profits, could not be found. Finally, in contrast to Fama, Fisher, Jensen and Roll(1969), the significant negative abnormal returns following the stock splits were still found irrespective of the change of dividend payout ratio.

This paper examines the disciplinary effect of deposits using the semiannual accounting data of mutual savings banks(henceforth 'MSBs') in Korea for the period of 2003 through 2007. I find overall strong evidence in favor of the existence of market discipline in the industry. MSBs with higher BIS ratio and lower NPL ratio turn out to have higher increase rate of deposits than MSBs with lower such ratios. The coefficient of NPL ratio becomes greater with time, suggesting that the effect is cumulative. It turns out that depositors respond more sensitively to NPL ratio than BIS ratio in a period of MSB failure. On the other hand, MSBs turn out to act very positively responding to the depositors' discipline. They increase BIS ratio or decrease NPL ratio following the previous decrease in deposits. Government authorities need to make more efforts to develop a suitable incentive system (e.g. penalties on a false disclosure) to improve the efficiency of disclosure by MSBs. Moreover, they need to acknowledge the importance of NPL ratio as a market disciplinary tool which has been becoming more important, especially in times of MSB failure.

The event of change in KOSPI 200 Index composition is one of the main subjects for the test of EMH. According to EMH, when a certain event is not related with firm's fundamental value, stock price should not change after the announcement of news. This hypothesis leads us to the conclusion of horizontal demand curve of stock. This logic was questioned by Shleifer(1986) and argued that downward sloping demand curve hypothesis was supported. But Harris and Gruel(1986) found a different empirical evidence that price reversal occurs in the long run, which is called price pressure hypothesis. They argued that short term price effect by large block trading (price pressure) is offset in the long run because these event is unrelated to fundamental value. Therefor, they argued that EMH can not be rejected in the long run. Until now, there are two empirical studies with Korean market data in this area. Using a data with same time period of $1996{\sim}1999$, Kweon and Park(2000) and Ahn and Park(2005) showed that stock price or beta is not significantly affected by change in index composition. This study retested this event expanding sample period from 1996 to 2006, and analyzed why this event was considered an uninformative events in the preceding studies. We analyzed a market impact by separating samples according to firm size and market condition. In case of newly enlisted firm, we found the evidence supporting price pressure hypothesis on average. However, we found the long run price effect in the sample of large firms under bearish markets. At the same time, we know that the number of samples under the category of large firms under bearish markets is relatively small, which drives the same result of supporting the hypothesis that change in index composition is a non-informative event on average. Also, the long run price effect of large size firms under bearish markets was supported by the analyses using trading volumes. On the other hand, in case of delisting from the index, we found the long run price effect but that was not supported by trading volume analyses.

본 연구는 미국과 유럽의 채권 전자거래에 대한 제도를 분석한 후, 우리나라의 채권 전자거래에 대해 시사점을 제시하고자 한다. 본 연구의 결과는 다음과 같이 요약된다. 첫째, 미국과 유럽에선 채권 전자거래 시스템(Electronic Trading System, 이하 ETS)의 영업행위가 원칙적으로 증권 중개업의 관점에서 규제된다. 이러한 방향의 규제 체계는 다양한 형태의 채권 ETS가 등장할 수 있도록 하여 채권시장의 발전에 기여한다. 둘째, 우리나라의 $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항 및 $\ulcorner$증권거래법시행령$\lrcorner$ 84조의27 6항은 다양한 형태의 채권 ETS의 등장을 원천적으로 봉쇄함으로써 채권시장의 발전을 저해하고 있다. 셋째, 현행 $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항은 주식 및 선물거래에 대해서 계속 적용하되 채권거래에 대해서는 그 적용이 유보될 필요가 있다. 이를 통하여 $\ulcorner$한국증권선물거래소법$\lrcorner$은 주식시장을 활성화 시키는 순기능을 유지하면서 채권 ETS의 등장을 원천적으로 봉쇄하는 역기능을 피할 수 있다. 넷째, $\ulcorner$한국증권선물거래소법$\lrcorner$ 15조 2항이 채권거래에 대해서 적용되지 않는다면, $\ulcorner$증권거래법시행령$\lrcorner$ 84조의27 6항은 삭제되어야 하며, 대신에 증권거래법은 채권 ETS의 활동 범위와 요건을 정의해 주어야 한다. 채권 ETS의 활동은 원칙적으로 증권업자의 중개활동으로 간주되어야 한다. 채권 ETS의 중개 규모가 일정 수준을 넘어설 경우 거래소에 준하는 보고, 공시 및 감시 요건이 부과되는 것이 바람직하다. 다섯째, 채권시장의 효율성을 강화하기 위해서 채권 ETS에 대해서 적용되는 투명성 강화, 시장분할 방지, 공정거래 등에 대한 규제는 거래 대상의 특성에 따라서 탄력적으로 조정될 수 있어야 한다.

This study aims to analyze why South Korea has not used audit system but examination system and suggest policy reform for the system on the institutional context perspective. Institutional context is structured down to institutional legacy, motives, institutional constraints, actors' roles, and changed institution. I researched the literature on the subject and collected research materials from the Department of the Treasury and Audit Office website of New Zealand, Australia, United Kingdom, United States and South Korea. These were analyzed using for suggesting realistic and effective policy. Analysis showed that South Korea has used examination system due to institutional constraints and tried to increase reliability of financial statements by enlarging the meaning of examination, strengthening the ability of the Board of Audit and Inspection, enacting government examination standards, and making a comprehensive public announcement. Comparing with other countries where government audit systems are applied, there are still some vulnerable points in South Korea. In order to make up for the shortcomings, this study suggests several points: strengthening the ability of actors; systemizing internal control; expressing opinion; making a more comprehensive public announcement. It would be desirable for making further detailed studies of the points.

This study analyzed the financing ratio by operation fund financing method and their impact on management performance according to the establishment operation management entity of the medical institution. For the analysis method, ANOVA, logistic regression, and regression analysis were conducted using financial information registered with HASPA.The results of the study, The ratio of gross revenue to operating funds differed significantly depending on the establishment operation management entity. In addition, it was found that the financing ratio of each operation fund financing method was significantly related to the management results(deficit, surplus), and the impact of the operation fund financing method on management performance differed according to the establishment operation management entity. As a result, the management of operating funds of medical institutions is deemed appropriate to apply cost management first considering the ratio of revenue to operating funds, and then to utilize internal operating funds.

Since the 1997 financial crisis, large scale unemployment and poverty have become serious, and public and social job creation projects have been carried out. However, with the limitations of low-wage and short-term jobs, the need for long-term and high quality jobs gradually began to attract attention. In recent years, social enterprises have grown both quantitatively and qualitatively and interest in social enterprises has increased. And also it is interested in the determinants of success and failure of social enterprises in the academic field. In this study, we examined the effects of social enterprise characteristics on financial and social performance, and we analyzed empirically by using social enterprises registered in the Korea Social Enterprise Agency. The financial performance of the social enterprise is measured by the net income ratio, operating income ratio, and the return on asset. The social performance of the social enterprise is measured by total number of workers and the employment rate of the vulnerable social groups. The characteristics of the social enterprise include the CEO characteristics (gender, age, experience in operating the social enterprise), the firm size, and the elapsed time of the authentication. The results of the empirical analysis are as follows. First, as a result of analysis for the effect on financial performance, we found that the financial performance have a statistically significant positive relationship with firm size, organizational form, government subsidies and capital adequacy ratio. And it is found that the social performance have a statistically significant negative relationship with CEO age, credit debt dependence. Second, as a result of analysis for the effect on social performance, we foumd that total number of workers have a significant positive relationships with CEO gender, CEO age, and firm size, government subsidies, while total number of workers have a significant negative relationship with certification type and industry dummy. On the other hand, the employment rate of the vulnerable social groups have a siginificant positive relationship with CEO gender and certification type and It have not statistically significant relationship with the government subsidies and the firm size.

In the past, because Korean private venture capital firms could get government support and subsidies, they could be survived in the market without having required management capabilities, advanced venture investment techniques, and professional supporting agencies and institutions. However, business environments have changed a lot recently. Now, only through identifying the optimal financial structures(the ratio of debt to equity), Korean private venture capital firms can minimize investment risks and ensure higher profits. Since Modigliani and Miller(1958) criticized the existence of the optimal financial structure, there have been numerous studies on the optimal financial structure of firms. However, there is no empirical study investigating the financial structure of venture capital firms. The purpose of this article is to analyze the relationship between firm characteristics, financial security indies, and financial profit indices of korean private venture capital firms. We gathered the data from various sources, including the web pages and the financial statements for 2003 and 2004. By using the student's t-test and the correlation analysis, we showed that there are differences in the current ratio and the ratio of net profit to net sales between new and old korean private venture capital firms. Even though it is known that korean private venture capital firms does not have enough knowledge and investment technique to compete with global venture capital firms, our result show that old korean private venture capital firms have already built some knowledge and understanding of venture capital investing.

The KPI of the four perspectives in BSC need to modify because of the change of management environment. In particular, the KPI of the financial perspective needs to modify necessarily. The KPI of financial perspective has been consisted of short-term measures: net profit current year, operating profit, ROE, ROIC, and EVA. But this financial indicators cannot afford to represent essential corporate sustainability management in the change of management environment. So this study suggests CSV(Creating Shared Value) as an additional KPI of financial perspective. And this study investigates whether CSV represents business performance as the additional KPI in BSC adoption firms. To verify a hypothesis, the sample includes listed firms announcing CSR index publicly between 2005 and 2010. The results of this study are summarized as follows. The high CSV firms is higher on the value relevance of firm in comparison with low CSV firms. Moreover, The firm value of BSC adoption firms is lower than otherwise, but it is insignificant. Limitation of Our study is that we have no choice but to use dummy variable. Because it is a material question as CSV measurement. Nevertheless, contribution of our study is to suggest new KPI of BSC perspective to meet management environment.
