According to disclosure regulation, insider can hide their trading until disclosure day, because there be interval between trading time and disclosure time. To accommodate strategic trade, they have an incentive to be brought disclosure interval as long as possible. This research investigate whether strategical behaviour of informed traders using disclosure intervals exists in domestic stock market.ls xt, we aney he whether they can get abnormal return through stealth strategy after announcement date. We also evaluate the effect of mimicking trading on price impact with the assumption of existence of mimicking trading. Our major research results are as follows: In case of main shareholder without having no prompt disclosure duty, the frequency of trading started at the beginning of month is shown significantly higher than others. This result shows a direct evidence that informed traders buy or sell their equity strategically using disclosure intervals. Also, we find the result that the coefficient of strategic variables has highest value in middle size information. However, the empirical evidence that informed trader get abnormal return through strategic trading was not shown in this study. Meanwhile, stock price over-reacts for selling transaction on trading point and is recovered after disclosure date., so we assume possibility of mimicking trading exists in domestic stock market.

This paper develops a simple model to explain the reasons why foreign acquirers pay significantly higher premiums for U.S. target firms than do U.S. buyers. We also provide empirical work on the valuation effect of foreign takeovers and the determinants of the wealth gains of U.S. target shareholders involved in foreign takeovers. The results indicate that target wealth gains are significantly higher in foreign takeovers than in domestic takeovers, after controlling for the wealth effects of payment method, acquisition type, tax status, size and time period of bids. This confirms the valuation effect of foreign takeovers. Furthermore, the results of cross-sectional regression analysis show that the variation in U.S. target wealth gains is explained by extra tax benefits stemming from double tax deductions for acquisition-related interest expenses incurred by foreign acquirers. These findings imply that differential taxation across tax jurisdictions is the main source of the valuation effect of foreign takeovers. In addition, we find that there exists a valuation effect of the nationality of the foreign acquirers. Japanese companies pay significantly higher premiums than do non-Japanese acquirers. The finding also indicates that competition among bidders increases the abnormal returns to U.S. target shareholders in foreign takeovers.

In this paper, we analyse empirically the relations between ownership structure and cash holdings of firms listed on Korea Securities Market and Kosdaq Market of Korea Exchange. The main results of this study can be summarized as follows. Cash holdings increase as large shareholder's equity holdings increase. Cash holdings increase as the difference between first largest shareholder's and second largest shareholder's equity holdings increase, and cash holdings increase as the ownership concentration increase. Managerial ownership exert a non-linear effects on cash holdings. So to speak, at lower level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders, but at higher level of managerial ownership, the interests of managers and shareholders are aligned, and also at highest level of managerial ownership, managers hold more cash to pursue their own interests at the expense of minority shareholders. Cash holdings increase larger in owner-controlled firm than in management-controlled firm. These results support the expropriation of minority shareholders hypothesis that large shareholders can extract private benefits from corporate resources under their control at the expense of minority shareholders. This paper contributes to defining information value of large shareholder's equity holdings on cash holdings for a firms' other stakeholders such as investors and creditors, and to strengthening a legal and institutional safeguard for external minority shareholders. Ownership concentration might have negatively affected the evolution of the legal and institutional frameworks for corporate governance and the manner in which economic activity is conducted. It could be a formidable barrier to future policy reform.

After IMF bailout crisis in Korea, project financing has been employed as a major funding vehicle for the housing development. In 2008, the recession of housing market due to the global financial crisis had an significant impact on the increasing insolvent site of PF based housing development project, resulting in serious impact to whole economy as a chain effect. In order to resolve this vicious circle of bankruptcy, the major construction companies were urged to take over the insolvent sites and invest to them for normal project exit, and finally play a critical role in normalization of market. Therefore, this study aims to define the core factors for decision making to invest to insolvent site and find out differences among constructors, developers, financial lenders. The results from AHP analysis, the profitability was the most important factor to constructors. Moreover, even though the location merit is little less, through competitive price, we can assure that stable profitability is most important factor to decide to invest in insolvent site. In conclusion, the price is cheap, is highly feasible, if the land secured, major construction company will participate in a PF business investment. These findings were verified by the investment case of major construction company.

'Venture firms' in Korea are the firms who are certified as 'venture', whose certification types are defined by a law ('Special Law for the Support of Venture Firms'), and therefore encompass not only the venture capital-financed companies, which are usually regarded as ventures in USA and European countries, but also other types of firms such as R&D-intensive firms and the firms with financial guarantee or loans through technology evaluation ('technology finance or loan firms'). This paper examines the differences in the Korean venture firms' growth between the venture certification types. For the empirical analysis, this paper uses the lists of venture-certified firms from 1998 to 2010 which are then linked with their financial data in Korea Enterprises Database (KED). According to the results of empirical analyses, the companies in the 'venture capital-financed firms' type show greater growth rate in sales and the number of regular employees 3 and 5 years after first venture certification than the firms in type of 'technology finance/loan firms'. Moreover, the newly certified companies in 'R&D-intensive firms' type are also showing faster growth than the 'technology finance/loan firms' since 2003 where the venture industry has undergone a consolidation phase after the blast of so-called 'IT venture bubble' in 2001~2002. These results imply that the so-called 'venture firms' in Korea are composed with heterogeneous firm groups with different characteristics and that the companies selected through market mechanism ('venture capital-financed firms') outperforms the companies selected on the basis of policy interests ('technology finance/loan firms') in terms of the growth in sales and employment. On the basis of these findings, this paper suggests that the current venture-support policy should consider the different policy demands of firms across the type of venture certification more actively and that should refocus the objective of policies on facilitating venture capital market rather than emphasizing the nominal increase in the number of venture-certified firms.

Despite the influence of real estate in the Korean asset market, it is not easy to predict market trends, and among them, apartments are not easy to predict because they are both residential spaces and contain investment properties. Factors affecting apartment prices vary and regional characteristics should also be considered. This study was conducted to compare the factors and characteristics that affect apartment prices in Seoul as a whole, 3 Gangnam districts, Nowon, Dobong, Gangbuk, Geumcheon, Gwanak and Guro districts and to understand the possibility of price prediction based on this. The analysis used machine learning algorithms such as neural networks, CHAID, linear regression, and random forests. The most important factor affecting the average selling price of all apartments in Seoul was the government's policy element, and easing policies such as easing transaction regulations and easing financial regulations were highly influential. In the case of the three Gangnam districts, the policy influence was low, and in the case of Gangnam-gu District, housing supply was the most important factor. On the other hand, 6 mid-lower-level districts saw government policies act as important variables and were commonly influenced by financial regulatory policies.

Maritime transportation is one of the oldest means of transportation utilized by mankind, and it has significantly contributed to the advancement of civilization by efficiently transporting bulk cargo at a low cost. The study aim to identify the factors influencing the selection of shipping companies in the bulk shipping market and provide insights for improving the competitiveness of shipping-related companies. To achieve this goal, the Analytic Hierarchy Process (AHP) was employed. For the empirical analysis, previous research, interviews, and a pilot test were conducted to identify five top-level factors such as companies, vessels, operations, services, and transaction factors. Each top-level factor has four sub-factors. The results of the analysis, based on 80 valid questionnaires, are as follows: Firstly, in the selection of shipping companies, the priority of factors influencing the choice of shipping companies was as follows: vessel factors were the most important, followed by company, operations, relationship, and service factors. Secondly, when investigating the priority of sub-factors, the availability/appropriateness of vessels was the most crucial factor, followed by company characteristics, financial soundness, and the company's reputation in order. The implications of these findings suggest that shipowners should focus on securing more suitable vessels and enhancing their reputation in response to shippers' demand. Shippers, on the other hand, should consider maintaining a healthy financial structure as a crucial task in securing competitive shipping service providers.

The advancement of Information and Communication Technology (ICT), along with the expansion of government and private investment in startup discovery and funding, has led to the emergence of startups seeking to generate outstanding results based on innovative ideas. As successful startups serve as role models, the number of aspiring entrepreneurs preparing to launch their own startups continues to increase. However, unlike entrepreneurs who challenge themselves with serial entrepreneurship after experiencing success, early-stage startups face various challenges such as team building, technology development, and fundraising. Accelerators play a dual role of mentor and investor by providing education, mentoring, consulting, network connection, and initial investment activities to help startups overcome various challenges they face and facilitate their growth. This study investigated whether there is a correlation between the characteristics of startups and their entrepreneurial performance, and analyzed whether accelerators mediate the relationship between startup characteristics and entrepreneurial performance. A total of 11 hypotheses were proposed, and a survey was conducted on 302 startup founders and employees located across the country, including the metropolitan area, for empirical research. SPSS 23.0 and Amos 23.0 were used for statistical analysis. Through this study, it was found that factors such as innovation, organizational culture, financial characteristics, and learning orientation among the characteristics of startups, rather than having a direct impact on entrepreneurial performance, are linked to entrepreneurial performance through the role of accelerators. By analyzing the impact factors of startup characteristics on entrepreneurial performance, this study presents research on the role of accelerators and provides institutional improvements. It is expected to contribute to the expansion of investment and differentiated acceleration programs, enabling startups to seize the market and grow stably in the market.

The miraculous growth of Korean economy and its business corporations during 1960' s and 1970's are mainly due to the government leadership and its market intervention. We can find the reasons why the government initiated economic growth plan was so successful in Korea in its efficient bureaucratic government system and fair discipline to the corporations based on its contribution to the economy. During 1960's, the primary factors for the growth of business entities and the formation of business groups were the financial special favor, the preferential treatment in the new industry entrance and the merge & acquisition, lavish export incentives from the government, and the export explosion to Vietnam. During 1970's, the substantial deduction of corporations' private debt, enormous support in heavy industry investment, special benefits to general trading companies by the government, and the construction export to the Middle-East were the main causes of the business growth and the business groups formation. Also, the economic rent for the big companies had still been effective since 1960's. However, the preferential benefit to the big companies made them to diversify into the unrelated business ares and to be in very vulnerable financial position. The governmental support brought about the monopoly as well.
