본 논문은 신용평가기관의 신용등급 변경공시 정보가 주식시장과 채권시장에 어떠한 영향을 주는 지를 1993년 1월에서 2001년 2월까지의 주식시장과 2000년 7월에서 2001년 2월까지의 채권시장에서의 자료를 이용하여 사건연구를 통하여 살펴본다. 주식시장의 경우를 살펴보면, 등급이 상승하는 경우는 신용등급 공시전이나 공시 후 유의한 반응이 관찰되지 않았다. 그러나 신용등급이 2등급 이상 하락한 경우는 등급 변경 공시 이전과 등급 공시일과 이후 모두에 유의한 반응을 나타냈으며 등급이 1등급 하락한 경우는 사건이 발생한 이후의 경우에서만 유의한 반응을 나타내었다. 채권시장에서는 등급이 상승하는 경우에는 투자수익률이 상승하고, 만기수익률이 하락하는 것이 관찰되며, 등급이 하락한 경우에는 투자수익률이 하락하고, 만기수익률이 상승하는 것이 관찰된다. 또한, 등급이 하락하는 경우가 상승하는 경우보다 그 변동이 크다.

This study examines shareholder wealth effects in tender offers and attempts to explain abnormal return variations of bidding and target firms at announcement of takeovers using the free cash flow hypothesis of Jensen. On average, bidders with large free cash flows pay higher premia (apparently more than fair market value) to targets than do other bidders with no free cash flows. Thereby, these bidders experience negative wealth effects on announcement of tender offers. Cross-sectional regression analysis suggests that for the subsample of takeover bids where bidders have large free cash flows, the increase in the debt ratio resulting from takeover has a significant positive wealth effect for bidding firm shareholders, while it has no effect in other subsamples. The evidence is consistent with the free cash flow hypothesis.

The residential comfort and safety on ship are more focused than ever, in accordance with the increase of the crews' onboard time and interest in cruiser sailing. To grasp the safety characteristics on ships against various scenarios of evacuations, this study performed experiments and simulations for the evacuation times on a training ship. Through the experiments, the average walking speed is 3.0m/s on 100% visibility, and 1.2m/s on 8% visibility, but the speeds go down 1.3m/s and 0.7m/s, respectively, when obstacles are happened without any previous notification. From the simulation, it is clearly reconfirmed that the worse visibility and many people make evacuation time comparatively longer. And unlike the common expectation of the effect of emergency announcement, the difference of evacuation times between cases of announcement and non-announcement is negligible on this study. From the survey after experiments, it is known that experiment participants feel unsafe and fear when the evacuation routes are longer in bad visible condition, even if they know the perfect evacuation route. And the survey results also show that the evacuees give more careful consideration to make a evacuation route decision under bad visibility.

Convergence is the process of gradual adoption of a certain accounting standard issued by different regulatory bodies. The aim is to achieve uniformity and standardization across borders to open opportunities for international investment and collaboration. The implementation of IFRS, in theory, encourages more transactions by presenting financial statements in a simple and understandable manner for all investors and other businesses interested in the company. Using event study methodology, this study investigates whether Malaysian companies' adoption of IFRS is recognized by the investment community. A total of 89 public listed companies in Bursa Malaysia are involved in this study. The results show that about 62.8 percent of the companies that adopted IFRS-based financial statements experienced an increase in their average abnormal return after the announcement. However, the paired sample test results show that only 5.6 percent out of 89 companies studied experience a significant difference in abnormal return before and after the announcement. The inexistence of the average abnormal return difference between before and after the announcement may indicate that IFRS-based financial statements do not have any new market informational content. This study found little evidence to show that convergence with IFRS affects the company's stock price in Malaysia.

Recently, many Korean firms have suffered financial losses and damaged firm's trust due to information security incidents. Hence, a lot of firms have realized the importance of the information security. In particular, the demand for information security certification has increased. This study examined the effect of information security certification using the event study methodology. Our research shows that the announcement of the information security certification significantly influences the market value of the corresponding firm. The certified firms rise, on average, o.4993% (-2 day), 0.5462% (+1 day) of their market value. Further, we found that the financial sector in our data showed a 1.4% higher abnormal returns than the nonfinancial sector. On the other hand, whether a firm first acquired the information security certification is not significant. Our paper presents that it is possible to analyze the effect of the information security certification using the event study. We are expected to be used in making a decision for the investment of information security. Also, our results indicate that the firm which have acquired the information security certification should actively announce that fact.

Previous studies provided mixed results on the synergy effect of M&A This study provides investigation on 39 mergers occurred over the sample period from 2000 to 2001. In this study, event study methodology arc used to calculate abnormal return(AR) and cumulative abnormal return(CAR) based on mean-adjusted model. The testing period of this study from date -30 through date +30, where date zero is the date of the first public announcement of the merger. The empirical results in this study can be summarized as follows. First, the return rates of KOSDAQ registered firms with M&A appears higher than that of KSE listed firms. This means that public announcement of M&A is more influential on stock price for KOSDAQ registered firms than KSE listed firms. Second, The difference between actual merging price and fair value is significant in KSE listed firms and KOSDAQ registered firms. This means that the investors take M&A of KOSDAQ registered firms as a good news. Third, the impact on the market prices of merging firms take place after the first public announcement of the merger in KSE registered firms. But the impact on the market prices take place not only merging firms but also merged firms in KOSDAQ registered firms. This result shows that the investors recognize a M&A is a strategy of technology transfer in small & venture business.

본 연구는 중소기업이 M&A를 할 때 중소기업의 집단적 특성이 합병의 공시효과와 합병 이후 장기영업성과에 미치는 영향을 분석하고자 2000년부터 2012년까지 우리 나라의 인수합병 사건 중 코스닥시장에서 중소기업법 제2조와 동법 시행령 제3조의 규정을 적용하여 선정한 중소기업의 사례 717개 사건을 표본으로 사건연구 및 영업현금흐름수익률을 영업성과변수로 하는 다중회귀분석을 실시하였다. 그 결과 첫째, 합병공시효과에 미치는 영향에 있어서는 기존의 한국자본시장을 대상으로 한 선행연구와 동일하게 중소기업 인수합병 사건에서도 규모효과가 존재함을 확인하였으나 다각화효과, 상장효과, 국제간인수합병효과는 확인하지 못하였다. 그리고 일반적 기업을 대상으로 한 선행연구 결과와는 다르게, 중소기업은 인수합병의 공시효과에 있어서 과거의 생산효율성이 높아 과거의 영업성과가 높은 기업들이 더 높은 초과수익률을 올리고 있음을 확인하였다. 둘째, 인수합병의 집단적 특성에 따른 영업성과에 미치는 영향은 비관련합병이 장기영업성과에 긍정적인 영향을 미친다는 기존의 선행연구와는 다르게, 평균적인 상장기업에 비해 열위의 시장경쟁력을 가지고 있는 중소기업의 특성상 동종기업과 관련합병을 할 때 생산의 효율성을 극대화하여 장기 영업성과에 긍정적인 영향을 미치고 있음을 확인하였다. 이러한 본 연구는 대기업의 산유물로만 여겨져 왔던 인수합병의 사례를 중소기업에 적용하여 인수합병의 공시효과와 집단적 특성에 따른 장기 영업성과에 미치는 영향을 살펴봄으로써 중소기업 인수합병 사건 연구에 새로운 시각을 제공하였다는 데에 큰 의미를 가지고 있다.

Purpose - The purpose of this paper is to investigate the relationship between earnings management and the disclosure effect of share repurchase. In addition, we analyze whether the relationship between earnings management and share repurchase is affected by executive stock options. Design/methodology/approach - We calculate the discretionary accrual amount for the year immediately preceding the share repurchase and the cumulative excess return around the announcement of the share repurchase, and examine the relationship between the two by regression analysis. Findings - We confirmed a negative relationship between discretionary accrual in the year immediately preceding the share repurchase and the market response to the share repurchase disclosure. In particular, it was found that the negative relationship between discretionary accrual and stock price return on share repurchase announcement was found to decrease in companies to which executive stock options were granted. Research implications or Originality - When uncertainties exist in the motives for share repurchase, we find that earnings management and executive stock options can be useful tools for reducing the adverse selection risk inherent in share repurchase announcements.

최근 인터넷의 급속한 발전과 기업의 정보 인프라 의존도가 높아지면서 정보 유출과 탈취, 변조 등 침해사고의 위험성이 급속히 확산되고 있다. 우리나라의 인터넷 사용빈도는 세계 최상위 수준이지만 정보보안은 그에 미치지 못하는 실정이다. 우리나라의 많은 기업들이 정보보안 사고로 인해 금전적 손실, 기업 이미지 훼손, 매출액, 순이익 감소 등 직간접적 피해를 경험하고 있다. 그러나 정보보안 사고에 대한 피해 규모를 계량화한 자료가 없어 올바른 정보보안사고 방지를 위한 투자의사 결정을 하기 어렵고 투자의 효과를 평가하기도 어려운 실정이다. 본 연구의 목적은 정보보안 사고에 따른 기업의 손실과 보안 투자로 인한 수익을 기업 시장가치의 변화를 이용하여 정량적으로 측정하는 데 있다. 사건연구방법론을 통해 분석한 결과에 따르면, 기업의 정보보안 사고는 평균 0.86%의 기업 가치 감소(시가총액 기준으로 약 540억)를 가져온 것으로 나타났다. 반면 기업의 보안 관련투자는 기업가치에 아무런 영향을 주지 않는 것으로 나타났다. 추가적으로 본 연구와 해외 연구결과와 비교해 보면, 국내 기업의 정보보안 사고가 기업 가치에 미치는 영향력이 상대적으로 매우 작은 것을 알 수 있었다. 이는 사회 전반에 걸친 보안 의식 제고가 무엇보다 시급함을 시사하고 있다.
