As an extension of previous researches with the conclusion that the announcement of adopting stock options generates positive abnormal returns, this paper examined whether the abnormal return changes over time or varies depending on the number of stock options granted. Empirical analysis was made to find whether the announcement of stock option awards has the same response in the stock market from the early days when stock option plans had been introduced in the Korean stock market till today when it was widespread. Results indicate that the announcement effect had been on a gradual decline since 2000. In addition, it is found that if a company announces stock option awards several times, the abnormal return gradually declines in proportion of the number of stock options granted. This implies that as the stock option awards become widespread, the positive effect that the announcement of adopting stock options generates as news has been on a relatively steady decrease. In short, it leads to a conclusion that the more companies grant stock options, and the more stock options a company announces, the less impact it has on the increase in the firm's value.

This study intends to discuss the influence on behaviors of won/dollar exchange rate after a FTA between Korea and US come into effect. The change of behaviors of won/dollar exchange rate has been looked into concerning other countries who have signed a FTA pact with the US, and these examples were compared with that of Korea so as to find similarities and differences. As a result of analyses, behaviors of exchange rate between FTA-pact countries were showed differently. Volatility and risk premium somewhat decreased after the FTA took effect except for Chile. As for Chile, showing intense volatility, foreign exchange risk premium rather increased. It can be concluded that the relationship between volatility and risk premium of individual exchange rate is established and FTA can influence change of these behaviors of exchange rate depending on the situation of individual country. This study will contribute to offer informations to Korea trading companies related to IT that will have to prepare for the uncertainties of change of exchange rate due to FTA between Korea and US.

T0901317 is a potent synthetic ligand for liver X receptor (LXR, NR1H2/3), a member of the nuclear receptor superfamily that functions as a transcription factor. However, T0901317 has been also reported to modulate the activity at least four other nuclear receptors (NRs), acting as agonists for farnesoid X receptor (FXR, NR1H4) and pregnane X receptor (PXR, NR1I2) and as antagonists for androgen receptor (AR, NR3C4) and retinoid-related orphan receptor-${\alpha}$ (ROR-${\alpha}$, NR1F1). We report here that T0901317 can also function as an inhibitor for constitutive androstane receptor (CAR, NR1I3). Since CAR is a major player of xenobiotic and cholesterol metabolism in the liver, along with PXR, FXR and LXR, which are reported to be regulated by T0901317, this further complicates the interpretation of potential results with T0901317 in liver cells.

This study intends to verify whether stock repurchase, as well as stock dispositions, affects shareholder's wealth and also whether repurchase/dispositions has varying impact de-pending on its purpose. According to empirical analysis, announcement of stock repurchase results in positive abnormal returns when the objective of stock repurchase is stock price stabilization or cancellation of shares. However, when the purpose of stock repurchase is granting incentives to executives/employees, we get the negative abnormal returns. Also, the termination of stock trust for reason of expiration or stock dispositions of which goal is to give incentives to executive/employees has a negative impact on stock price, whereas direct dispositions of stock to raise cash or to improve financial structrue are shown to significantly increase the wealth of shareholders. Cross-section analysis also confirms that stock repurchase and dispositions has different impact on excess returns depending on its purpose. The results of this study imply that the dispositions of stock should be regarded as an important financial strategic tool to be used by companies and what's more, such studies dealing with stock repurchase or dispositions should take firm's purpose into consideration in their approach.

Second, active industry-academia cooperation should stimulate entrepreneurship education and entrepreneurship based on university resources. Third, it should act as an anchor of regional innovation by actively cooperating with local innovation entities.

In this study, the relationship between R&D investment and firm value was approached from ESG's G(governance) perspective to verify the moderating effect of the corporate governance and ownership structure. To this end, a panel analysis was conducted on a total of 2,825 samples of 405 manufacturing companies listed on the KOSPI market during 2013~2020. The main analysis results are as follows. First of all, we found that R&D investment has a negative impact on firm value, at least in the short term, and that these relationships are moderated by corporate governance and ownership structure. When professional CEO with high level of expertise in business and management does lead R&D investment, the negative impact of R&D investment on firm value is mitigated compared to owner-manager. Also, the stronger the power of outside blockholders, the more transparent the management and disclosure of information, alleviating the information asymmetry between internal and external shareholders, which mitigates the negative impact of R&D investment on firm value. The findings suggest that the factors of ESG may not only have a direct impact on firm value, but also have a moderating effect on firm value.

In this study, we hypothesized that the needs for start-up support services may vary depending on the founder's psychological characteristics, such as self-efficacy or his attitude toward uncertainty. To verify this, a survey was conducted on the founders of 86 companies located in Business Incubators at Seoul and Daejeon and an empirical analysis was conducted based on the data. According to the analysis, the higher the self-efficacy of the founder, the more active he expressed his willingness to accept the start-up support service, which aims to provide start-up zones to busy areas outside the university. While the founder, who has experienced failure in the past, responded positively to attracting customers located outside the university. The results of this study supported the hypothesis and suggest that differentiated start-up support services should be designed by including not only characteristics at the level of start-up companies, such as industries and growth stages, but also the psychological characteristics of start-ups in important consideration.

This study analyzed the effect of manager's ability on compensation policy (compensation level and performance-reward sensitivity). To this end, the final 14,150 company-year data were used for KOSPI and KOSDAQ listed companies excluding the financial industry from 2012 to 2019. As a result of the empirical analysis, the higher the manager's ability, the higher the next reward level (the manager's ability hypothesis), but the performance-reward sensitivity decreased. This confirms the manager ability hypothesis through a positive (+) relationship between manager ability and compensation, and means that high compensation for manager ability may be additional compensation for manager ability other than performance, rather than due to performance. This study differs from previous studies and has contributions in that it examines the more complex effects of managerial ability and compensation system.

This paper examines what factors contribute to the entry of foreign investors to Chinese commercial banks from 1996 to 2008. Empirical results show that using survival analysis, size, liquidity ratio and non-interest incomes are important to foreign investors. This indicates that as Chinese banking system opened, foreign investors invest in bigger but financially weak banks. For Joint-Stock commercial banks, foreign investors invest in banks whose asset qualities and non-interest incomes are low. But for City commercial banks, foreign investors invest in banks that are big but have low liquidity ratios. This results indicate that because City commercial banks operate in only one city, foreign investors require minimum bank size to operate in that city.
