Purpose - This study addresses an acquisition's impact on a firm's strategic relationship based on findings of existing academic studies and theoretical assertions. Through examining existing research results and theoretical grounds for an acquisition's impact on various stakeholders, this study indirectly approaches the impact on stakeholders including alliance partners. Research design, data, and methodology - This research identified a variety of related theoretical foundations and empirical studies. Research objectives of prior studies mainly focused on merging firms and direct participants of acquisition activity. In addition, academic attention on the impact on rival firms has recently been growing. However, little research on alliance partners was found. Prior studies simultaneously employed event study methodology and cross-sectional analysis to make further theoretical contributions. Results and Conclusions - Based on the findings of prior studies, this research proposed a complementary research model for future academic inquiry into the impact of an acquisition on an alliance partner's return and for predicting an acquisition announcement's effect on alliance partners.

Objectives: This study was conducted to investigate derived factors associated with a public service announcement on handwashing to evaluate the effect of this announcement. Methods: In early september, 1,000 persons over 19 years old was investigated by Computer Aided Telephone Interview, at last 993 persons for analysis. Outcomes were the exposure to the public service announcements on handwashing, the comprehension of this announcements, the intention of behavioral change and the practice of handwashing. Results: In particular, the proportion of exposure is more women and highly educated. The comprehension of the announcement was no statistically significant difference. The intention of behavior change showed higher in workers and understanding of the announcements. The practice of handwashing is higher in women and lower in student/unemployed. There was no difference in practice in accordance with the exposure, the comprehension and the intention of behavioral change. Conclusions: About the comprehension of the announcements and the intention of behavioral change, the effects of the public service announcements on handwashing can be very positive. But it does not affect the actual practice of hand washing. The handwashing promotion programs will have to devise a strategy and structure, operation method considering realistic and scalable platform.

본 연구에서는 국내 상장기업이 발행한 전환사채 표본을 대상으로 전환사채 발행 공시효과 및 공시효과에 영향을 미치는 요인을 조사하고 이러한 제반 효과가 기업지배구조를 중심으로한 기업의 재무적 특성과 어떠한 연관이 있는지 살펴보기 위해 재벌 여부를 포함한 주요 기업지배구조 변수를 이용하여 실증 분석하였다. 분석결과 전체표본에서 일본의 경우와 유사하게 공시일 주변 주가반응이 유의한 양(+)의 값으로 관찰되었다. 하지만 이러한 양(+)의 주가반응은 대부분 비재벌기업에 기인한 것이었다. 재벌기업의 경우 공모전환사채에서 양(+)의 비정상수익률이 관찰되지 않은 반면에 사모전환사채에서는 오히려 유의한 음(-)의 값이 측정되어 전체표본 및 비재벌기업과 달리 재벌기업의 전환사채 발행은 긍정적인 경제적 효과를 거두지 못하였다. 이러한 부정적 주가반응은 재벌의 사모전환사채 발행에 여타 중권에서와 다른 경제적 목적이 개입할 소지가 높다는 사실을 보여주는 것이라고 할 수 있다. 횡단면회귀분석을 통해 기업가치 변화의 원인을 분석한 결과 대주주지분과 같은 소유구조, 재벌여부, 은행과의 밀접도 둥의 지배구조변수가 주가변화에 상당한 영향을 미치는 것으로 나타났으며, 이러한 영향은 특히 사모전환사채 발행에서 두드러지게 나타나 공모보다 사모에서 기업지배구조가 보다 중요한 역할을 수행한다는 사실이 판명되었다. 마지막으로 재벌의 사모전환사채 발행 공시에 따른 주가하락이 소유경영자의 대리인문제에 기인한 것인가를 검증하기 위해 실시한 로짓회귀분석에서 대주주지분이 낮은 재벌일수록 사모를 이용하는 경향이 높게 나타나 재벌의 사모발행에 따른 주주 부의 손실이 소유경영자의 대리인문제에 기인할 가능성이 크다는 사실을 발견할 수 있었다.

Purpose - The most important goal of corporate management is the maximization of firm value in the market. Executives of companies are making effort to increase corporate value and initiate various management strategies, which is to develop the products or service with value. Through these efforts, consumer satisfaction grows and loyalty increases, which leads to the positive change of customer satisfaction index. The purpose of this research is to find out the abnormal return after the KCSI(Korean Customer Satisfaction Index) is announced. Research design, data, and methodology - This research data is collected from 11 years' stock price in KOSPI market and KCSI. The authors analyze the abnormal return triggered by the announcement of KCSI through the event study. Results - First, newly enlisted companies in the KCSI show statistically significant short-term abnormal rate of return. Second, the value of the customer satisfaction index is not the level of customer satisfaction but the direction of the change in the CSI. Conclusion - Customer satisfaction has the important intangible asset in the marketing area. However, firms' investment for CS is not an easy decision, because of the difficulty to measure the effect on corporate market value. This research investigates the change of the market value after the announcement of KCSI. Based on the results, firms have to keep trying to increase KCSI relative to the previous year. And the small company has to struggle for being newly listed in the KCSI.

In the past few years, many Korean companies have implemented various ERP systems. Despite the enormous efforts and costs, however, there have been doubts about the effectiveness of ERP implementation. The purpose of this study is to identify whether the announcement of ERP implementation affects the market value of the firm. To achieve the research objective, event-study methodology was used assessing the cumulative abnormal returns(CARs) for 33 firms' announcements of ERP investments. Findings of the study are summarized as follows: First, the announcements of ERP implementation have no effect on the firm value though the sign is negative. Second, there is marginally significant difference in the market value of the firm between the first mover of ERP implementation and its followers. In order to figure out any possible reasons of such unexpected results, several investors and fund managers of major investment firms were interviewed. They reached the two agreements that ERP hardly increases the firm value. One was mainly due to the misfit between the foreign business processes built in the ERP systems and Korean firms' traditional business processes. The other was the possibility of financial deterioration caused by substantial costs for ERP implementation.

This study explores the impact of the COVID-19 pandemic on the stock prices of state-owned enterprises listed on the Indonesia Stock exchange. The impact of the pandemic is analyzed based on different pandemic phases and the corresponding government pandemic interventions to curb the disease. This study analyzes 6 pandemic event dates, covering the time period from January 2020 to February 2021. A total of 20 state-owned enterprises are included as the sample of this study. Test of difference is employed to compare the stock prices of the state-owned enterprises before and after each pandemic event date. In general, this study confirms the adverse impact of the COVID-19 pandemic on the stock prices, especially the event in 2020, although some variations do exist. The results of the study reveal a significant decrease in the stock prices of the state-owned enterprises after the announcement of the first confirmed COVID-19 cases, the announcement of COVID-19 as a global pandemic, the imposing of Large Scale Social Restriction (PSBB I and PSBB II). In contrast, the stock prices increase after the imposing of a new normal policy and the imposing of Public Activity Restriction (PPKM). This study also documents that the effect of the pandemic may vary based on the pandemic phase.

본 연구에서는 KOSPI, KOSDAQ 상장기업이 인수주체가 되어 스타트업을 피인수 대상으로 인수합병한 경우, 단기적으로 인수기업의 주가에 미치는 영향을 분석하였다. 연구대상기간은 외환위기의 영향을 고려하여 외환위기가 발생한 이후인 2002년 1월부터 2014년 12월까지로 정하였다. 이 기간 동안 발생한 국내기업의 인수합병사례 총1436건 중 인수기업이 비상장기업인 경우 53건을 제외하고 1383건을 연구대상 사례로 선정하였다. 분석 결과, 첫째, 합병공시일 전후 (-2, +1), (-5, +2), (-10, +5)의 기간 동안 발생한 전체표본집단(n=1383)의 인수기업 누적평균 초과수익률(CAR)과 피인수기업이 설립된 지 5년 이내 신생기업(이하 '스타트업'으로 표기)인 부분표본집단(n=468)의 인수기업 누적평균초과수익률을 비교한 결과, 전체 표본집단의 경우 인수기업은 모든 구간에서 유의하지 않은 누적초과수익률을 보인 반면, 스타트업을 합병한 경우에는 모든 구간에서 유의한 양(+)의 누적평균초과수익률을 보였다. 이는 스타트업과의 인수합병이 인수기업의 기업가치에 긍정적인 영향을 미친다는 것을 보여주고 있다. 둘째, 스타트업이 상장기업일 경우에는 모든 구간에서 통계적으로 유의하지 않은 누적초과수익률을 보이는데 반해, 비상장 스타트업 기업을 합병할 경우에는 모든 구간에서 양(+)의 누적평균초과수익률을 나타내었다. 이는 스타트업 기업의 인수합병 시에도 일반적인 합병에서 나타나는 상장효과(Listing effect)가 존재하고 있음을 보여주는 것이다. 셋째, 하이테크 산업에 속한 스타트업을 합병할 때 비(非)하이테크 산업에 속한 스타트업을 합병하는 것보다 더 높은 초과수익률을 올리는 것을 확인할 수 있었다. 본 연구는 스타트업과의 인수합병 공시효과에 대한 국내의 첫번째 연구로서 그 의의가 크다고 할 수 있다.

Purpose - The purpose of this study is to re-examine the disclosure effect of stock splits and long-term performance after stock splits using stock split data over the past 10 years, and infer the motivation (signal or opportunism) of stock splits. In addition, we focus on exploring the determinants of the short- and long-term market response to stock splits. Design/methodology/approach - We measure the short-term market response to a stock split and the long-term stock performance after the stock split announcement using the event study method. We analyze whether there is a difference in the long-term and short-term market response to a stock split according to various company characteristics through univariate analysis and regression analysis. Findings - In the case of the entire sample, a statistically significant positive excess return is observed on the stock split announcement date, and the excess return during the 24-month holding period after the stock split do not show a difference from zero. In particular, the difference between short-term and long-term returns on stock splits is larger in companies with a large stock split ratio, small companies, large growth potential, and companies with a combination of financial events after a stock split. Research implications or Originality - The results of this study suggest that at least the signal hypothesis for a stock split does not hold in the Korean stock market. On the other hand, it suggests that there is a possibility that a stock split can be abused by the manager's opportunistic motive, and that this opportunism can be discriminated depending on the size of the stock split, corporate characteristics, and financing plan.

본 연구는 정보유출에 따른 주가반응을 측정함으로 정보유출이 기업가치에 주는 효과를 분석한다. 정보유출기업은 사건발생 2일 이내에 평균 1.3%의 시장가치를 상실하여 98.9백만원의 손실액이 추산된다. 우리는 원천, 유형, 크기 등 다양한 정보유출 유형에 대한 비정상수익율을 분석하였다. 시장은 외부원천의 정보유출에 유의미한 반응을 하지 않지만, 내부원천의 정보유출에는 통계적으로 유의미한 반응을 보였다. 우리는 60일간의 장기 비정상수익율을 추정하였다. 60일 평균 누적비정상수익율과 매입보유 비정상수익율 모두 유의미한 시장반응을 보인다. 이로써 우리는 정보유출사건 이후 일관된 시장반응이 있다고 결말지을 수 있다. IT기업과 비IT기업의 시장반응 차이는 통계적으로 유의미하다. 그러나 유출규모, 기업크기, 발생시점 등은 유의미한 시장반응을 보이지 않는다.
