Purpose - The purpose of this study was to examine the relationship between firm's non financial performance and its shareholder return by analyzing PCA while focusing on the classifying all the variables into three categories such as financial, characteristics, and non financial factors of the firms. Design/methodology/approach - By exploring the pattern of self tender from the 801 firms in KOSPI while focusing on the objective of stock disposal, this paper analyzes the change of shareholder return of the firm. Findings - First, the higher major ownership, the lower self tender gets, whereby the higher ownership by foreigners, the ratio of self tender is higher. Secondly, cash dividend has not significant impact on the disposal of self stock, and the high ratio of ownership by foreigners leads to the high probability of retirement rather than the general disposal. In contrast, the major ownership has a negative impact on the general disposal as well as retirement. Thirdly, the score of non financial factors such as Environment(E), Social responsibility(S), and Governance(G) shows the high value in case of the firms with self tender. More specifically, the firms with retirement has the highest value of ESG while it has the lowest value in case of the firms with general disposal. Research implications or Originality - The retirement which means the active shareholder return is strongly affected by the non financial factors. Specifically, the probability of retirement increases in case of the firms with retirement, and even such a tendency is found to the case of the firms with general disposal.

China has been experiencing high economic growth along with massive change in its industrial structure. How will the industrial structure change affect the Chinese economy? Similar changes were observed by Japan, when the Japanese banking system fell into a structural failure in terms of the inability to respond to the paradigm shift from "catching up" to "frontier economy." This paper is undertaken to highlight the lessons that China can learn from Japan's prolonged financial slump. We point out that big cities in China have already shifted to frontier economy and major provinces are on the same trend. We argue that in spite of economic reform reshaping the Chinese banking system, the financing pattern of state owned commercial banks (SOCB) is not in line with the industrial change. The Chinese banking system should be overhauled or transformed to respond to the increasing uncertainty along with the paradigm shift. Otherwise, China may fall into the same dilemma that Japan had faced in its industrial structure change.

Considering the existence of asymmetric information between doctor and patient, the doctor's reimbursement method has been considered as a desirable policy device of improving efficiency of patient's use of medical care in terms of its affecting doctor's practice pattern by determining doctor's practice revenue. By using the Community Tracking Study (CTS) physician data set, which includes not only various information on doctors practice arrangements and sources of practice revenue, but also vignettes of various clinical presentations, this paper investigates doctor's reaction to the financial incentive under the control of patient's specific medical situation. Under the econometric model for exploring the effect of doctor's reimbursement method on his/her practice patterns; referring patients, recommend doctor-visit or medical tests, the Hausman's specification test was used for checking out the possibility of the doctor's reimbursement method being endogeneized explanatory variable. In the case where the endogeneity problem of doctor's reimbursement method exists, the 2SLS method was used for correcting that problem, and the multiple regression method was used in the case where the problem is found to be nonexistent. Based on the empirical results, this paper finds that doctors do appear to respond to financial incentive. The empirical results show that the doctor's reimbursement method statistically significantly affects doctor's practice pattern and are coincident with the theoretical result proposed by previous researches, This results suggest, as doctor's practice revenues are mainly determined by prospective method, such as capitation, doctors would more refer their patients to specialists, and hesitate in recommending doctor-visit or medical exam.

In this Paper, an attempt is made to establish a learning framework for robust planning and real-time execution control. Necessary definitions and concepts are clearly presented to describe real-time operational control in response to Plan disruptions. A general mathematical framework for disruption recovery is also laid out. Global disruption model is decomposed into suitable number of local disruption models. Execution Pattern is designed to capture local disruptions using decomposed-reverse neural mappings, and to further demonstrate how the decomposed-reverse mappings could be applied for solving disrubtion recovery problems. Two decomposed-reverse neural mappings, N-K-M and M-K-N are employed to produce transportation solutions in react-time. A potential extension is also discussed using the proposed mapping principle and other hybrid heuristics. Experimental results are provided to verify the proposed approach.

This study uses financial statements on several hundred companies listed in the Korea Stock Market to analyze trends in inventory turnover ratios and examine the effect of inventory performance on the profitability of the companies. Statistical analyses are done to determine if there have been significant changes in inventory turnover ratios and how turnover ratio pattern varied by factors such as industry, size of the firm, and the effectiveness of previous inventory management. Inventory turnover ratios decreased for four consecutive years and were found to vary by industry. Also it is proved that there was statistically significant relationship between the size of the firm and the average level of inventory as a fraction of sales. Regression analysis is done to investigate the relationship between the inventory management performance and profitability of companies and it is found that improvement in inventory level affected profitability of the companies.

In this study we examine the long term behavior of stock returns. The analysis reveals that negative autocorrelations of the returns exist for a super-long horizon as long as 10 years. This pattern, however, contrasts to predictions of previous stock price models which include random walks. We suggest the introduction of a fractionally integrated process into a nonstationary component of stock prices, and demonstrate empirically the existence of the process in NYSE stock returns. The predicted values of autocorrelation from our stock price model confirm the super-long term behavior of the returns observed in regression, indicating that inefficiency in the stock market could remain for a long time.

본 연구에서는 금융위기를 전후하여 기업이 보유한 부동산 중 업무용부동산과 투자부동산의 보유비중이 어떻게 변화되었는지를 분석하고, 이 부동산의 보유비중이 금융위기를 전후하여 코스피기업과 코스닥기업간에 차이가 있는지 여부를 분석하였다. 코스피기업의 경우 투자부동산은 개략적으로 증가하고 업무용부동산은 개략적으로 감소하였다. 코스닥 기업의 경우 금융위기 중의 투자부동산을 제외하고 코스피기업과 유사하였다. 평균차이분석을 이용하여 코스피기업과 코스닥기업을 비교해보면, 금융위기 직전에는 코스피기업의 보유부동산비중이 코스닥기업의 보유부동산비중 보다 투자와 업무용 모두 낮았으나, 금융위기 중 구간에는 코스피기업의 업무용부동산비중이 코스닥기업의 업무용부동산비중 보다 높아졌으며, 금융위기 직후 구간과 최근 구간까지는 코스피기업의 투자부동산비중이 코스닥기업의 투자부동산비중 보다 높게 유지되고 있었다. 본 연구는 금융위기 전후의 업무용부동산과 투자부동산의 변화 현상을 파악하는 목적이며, 이 분석결과를 토대로 경영성과와의 관련성 파악을 향후연구과제로 남긴다.
