Purpose: The paper contributes to the existing literature on Vietnamese corporate governance and firm performance with a focus on listed family firms and the use of a more suitable econometric framework to analyze firm performance. The study investigates how family firm performance is affected by corporate governance under the standpoint of stewardship theory in Vietnam. Research design, data and methodology: With the use of different measures for firm performance (Tobin's Q, ROA, and ROE), regression models were estimated using Generalized Least Square (GLS) method on a panel data of a total of 113 listed companies during the five-year period from 2015 to 2019. Results: We found that family ownership as the main characteristic of the stewardship theory affects family firms positively. In addition, several other characteristics in corporate governance as board composition (board independence, board audits, and board committees), CEO (age and tenure) and firm characteristics (size, age, expansion, and annual sales) showed significant impacts on firm performance. Our findings also suggest that family firm performance can be either positively or negatively affected based on the characteristics of corporate governance. The findings can help companies evaluate the significance of corporate governance through deciding board structure and the selection of CEOs to match family firm characteristics. It also gives insights for investors, rating agencies, and policymakers for relevant purposes.

Purpose - This paper investigates the long term impact of RFID investment on firm value in Korea. We wand to find out why the long term performance of some firm's RFID investment is better than others. To understand the dynamics of the long term returns from RFID investment announcements, we divide our events into groups for each of the independent firm characteristic variable such as investment time period, kind of markets, industries, solvency and growth potential. We composed portfolios based on the RFID investment announcement date for each group and evaluate the monthly abnormal excess returns. Research design, data, and methodology - Based on these calendar-time portfolios, we measure the long term returns from 86 RFID investment announcements of 46 firms from 2003 to 2017. We construct the calendar-time portfolio for 3, 6, 9, 12 months of holding periods. Using the weighted least squares method, we regress the raw monthly returns of the portfolios on the Fama-French model and Carhart(1997) model. As a result, we can get the estimated risk adjusted mean monthly abnormal excess return α_P for each of the calendar-time portfolio. Results - We found that early adopters, large firms, non-manufacturing firms have very significant excess returns. We also found modestly significant excess returns for financially stable firms and slow growing firms. Put together, top managers of the firms which plan to invest RFID should understand the strategic role of RFID adoption and the generalized business process of distribution information technology investment in Korea. Moreover, the findings of this paper provide useful trading strategies to the managers of large funds who are considering on investing in RFID adopting firms. Conclusions - Put together, the results of this paper give us a new insight into how the RFID and IT technology in general and other characteristic factors' interactions affect the long term performance of firms. Using the unbiased estimates of long term returns of the calendar-time portfolios, this paper extends the understandings on short term impact of RFID adoption of existing studies. This paper also extends the current understandings of firm characteristics that affect the long term performance of RFID adopting firms.

The paper investigates the mechanism through which corporate credit ratings affect dividend payments by decomposing the mean difference of dividends into a part that is explained by the determinants of dividends and a residual part that is contributed by the pure credit group effect, in the framework of the traditional dividend model of Fama and French (2001). Historically, better credit rated firms have shown consistently higher propensity to pay dividends especially during the economic crisis period. According to the counter-factual decomposition technique of Jann (2008), better rated firms are more responsive to the firm characteristics that have positive impact on dividends and poor rated firms are more responsive to the negative dividend predictors. As a result, good (bad) credit ratings make corporate managers become more bold (timid) in their dividend payments and they tend to pay more (less) dividends than what their firm characteristics prescribe. The degree of information asymmetry increases for the poor group firms during crisis periods and they attempt to reserve more cash in preparation for future investments. The decomposition results suggest that the credit group effect can potentially exceed the effect of firm characteristics because firms of different credit ratings can respond to the very same firm characteristics in a different manner.

본 연구는 한국거래소의 코스닥증권시장에 상장된 기업들을 대상으로 연구개발투자와 기업가치 간의 관계를 살펴보았다. 주요 결과는 다음과 같다. 첫째, 표본기업 전체를 대상으로 실시한 분석결과, 연구개발투자는 기업가치와 역 U자 형태의 비선형적(nonlinear)인 관계를 지니는 것으로 나타났다. 이러한 비선형적인 관계는 연구개발투자가 일정한 범위까지 기업가치에 긍정적으로 기여하지만, 일정 수준을 초과하는 경우 오히려 기업가치에 부정적인 요인으로 작용할 수 있음을 의미한다. 둘째, 제조기업 및 IT기업 여부 등의 기업특성과 글로벌 금융위기 발생 시점을 기준으로 구분한 하위 집단의 분석결과, 대체로 연구개발투자와 기업가치 간에 역 U자 형태의 비선형적인 관계를 지니는 것으로 나타났다. 그러나 일부 하위 집단에서 양(+)의 선형적 관계가 발견되었고, 추정계수의 크기 및 통계적 유의성도 다양하게 나타났다. 이는 기업특성과 금융위기 등이 연구개발투자와 기업가치의 관계에 부분적으로 다른 영향을 미칠 수 있음을 의미한다. 이와 같이 본 연구의 결과는 연구개발투자를 결정하는 경영자와 관련 기업의 투자자에게 중요한 정보로 활용될 수 있다는 점에서 시사하는 바가 크다.

This thesis has studied about the legal characteristic of injection of the trial drug, the position of the pharmaceutical firm as a contractor of the clinical trial, the possibility of compulsory performance of consistent injection of the trial drug, and the damage claim caused in the process of the clinical trial from the viewpoint of protecting the trial subject in the clinical trial. According to court's judgement in the United States, the lawsuit of the trial subject, although the trial subject had expected consistent injections, was dismissed because there was no direct contract between pharmaceutical and trial subject. However, Helsinki Declaration prescribe the medical research as follows. 'All patients who participated in the research should be able to use the best precaution, diagnosis, and treatment proved by the final outcome of the research'. The trial subject is entitled to demand only the pharmaceutical firm which developed and provided the trial drug, and the pharmaceutical firm has the obligation to supply the trial drug to the trial subject. Therefore, it would be not enough to protect the trial subject if the pharmaceutical firm which makes the trial drug is ruled out. In addition, especially, in case the trial drug has a constant effect with the aim of treatment, if the injection of the trial drug is suddenly stopped, the trial subject would not have the benefit of treatment by the trial drug. In this case, the best remedy against the damage is to urge a constant injection of the trial drug. Thus, in certain case, it is reasonable to consider that the pharmaceutical firm has the obligation to supply the trial drug to the trial subject constantly, and it is also necessary to compel it through effective means in case the pharmaceutical firm do not fulfill its obligation to supply the trial drug. However, as an essential prerequisite for the assertion mentioned above, it should be judged under the principle of good faith considering the concrete situation, that is, what roles the pharmaceutical firm has played.

This study tests e-business performance difference of the inter group by strategy type through the cluster analysis, after confirming the linear relationship between the e-business strategy type and its performance. According to the result of the study the effect on the e-business performance reveals to differ by the e-business strategy type. That is to say, while the firm's information system performance, e-business realization and the inter group competition dominance are affected positively by the e-process strategy, web application strategy and customer attracting strategy. This confirms that the information system performance, the realization performance and the competition dominance are affected by e - business strategy type. The key factor leading to the success of e-business is the commitment of e-process strategy and web application strategy. For the case of the customer attracting strategy the result shows the importance of the strategy. In the cluster group analysis, the additional analysis, the effect is seen to be more powerful in the firm's information system performance, e - business realization and securing the competition advantage for the case of the multiple strategy than that of single one. Accordingly, the firm needs to adopt the multiple strategy suited for the characteristic of the firm rather than the single strategy.
