Since 1993, M&A activities have been frequent in Liner shipping market. This study examines the effect of M&A on stock price reaction for acquiring firms listed on the market. The study covers the period from 1993 to 2009 and uses 61 daily closing prices of the acquiring firms before and after the M&A announcement day and is analyzed through the market-adjusted model in an event study. After calculating short-term performance using abnormal returns(AR) and cumulative average abnormal returns(CAR) before and after 30 days from the day of event, the results on the test show that the firm's values slightly increased through the M&A, but it does not attest to the statistical significance. In addition, this study investigates the AR difference between estimating windows and post-event windows for the 3 cases of each period before and after 30 days, 15 days, and 7 days from the event day to analyse the impact of M&A on the addition of acquiring firm's value. Our findings suggest that the M&A between Liner shipping companies is targeted for the long-term business strategy instead of the instant rise in the value of the firm involved.

최근 들어 벤처 기업들 간의 손잡기가 눈에 띄게 늘고 있다. 이는 굳이 합병이나 인수의 형태가 아니라도 업무 제휴 기술제휴, 공동개발, 공동 출자등 다양한 형태로 나타나고 있다. 이것은 비단 우리나라만의 현상이 아니다. 미국 또한 이미 수년 전부터 벤처기업들 간의 인수 합병이 있어왔고 현재까지 이어지고 있다. 우리나라의 경우 아직도 두렷한 인수나 합병은 나타나지 않고 있다. 이것은 여러가지 측면에서 분석이 가능하다.

Despite the recent rapid advancement of science and technology, we have been experiencing the decline in productivity since the 2000s. This study aims to investigate the decline at both industry and firm levels, by looking at the emergence and growth of large firms such as Amazon, Alphabet, and Apple and M&A trends. Following the results of previous studies, our results show that productivity at industry level has decreased since the 2000s. Particularly, in the period after 2011, the deterioration of allocative efficiency due to the large firms and the decline in the growth rate of surviving firms in the industry with low ratio of large firms contributed to the productivity decline. On the other hand, our analysis at firm level demonstrates that the productivity of firms that acquired IT firms improved over the entire period. While M&As have a positive impact on productivity, M&As with a demand-side motive such as market penetration and expansion of channels have a relatively larger impact than the ones for production or operation efficiency. Our results also suggest that the higher the proportion of large firms in a specific industry, the lower the productivity of individual firms in the same industry. Overall, given that the industry's structural changes for digital transformation tends to strengthen the growth of large firms, our findings have significant implications by empirically identifying the relationships of the emergence of large firms, the acquisition of IT/Non-IT firms, and motivations for M&As to firm/industry productivity.

This study investigated the effect of tender-offer on the value of the firms in Korea. For this purpose, the study applied an event study methodology to 55 cases(bidding firm : 26, target firm : 39) of tender-offer and 164 cases(bidding firm : 144, target firm : 20) of merger announcements made between January 1st, 1994 and September 30th 2004. We found the following results. For tender-offer announcements, there was a significant increase in target firm's value while there was no significant change in bidding firm's value. In contrast, for merger announcements, there was a significant increase in bidding firm's value while there was no significant change in target firm's value. In addition, the synergy effect of tender-offer was higher than that of merger. The results support the Berkovitch and Khanna(1991)'s prediction that bidding firms choose tender-offer rather than merger in the presence of higher synergy profit from M&A.

The success of mergers and acquisitions(M&A) have been evaluated by either measuring ex ante expectations for the specified time period(Window) or assessing long term-based post operating performance (ex post operating performance). In this study, utilizing cumulative abnormal return(CAR) method, M&As which are observed in both domestic and U.S. construction industries were analyzed then research outcomes are compared. Analysis results indicate that stockholders of public construction companies did not realize significant economic gains from M&As. In other words, there was no synergistic gains from the construction M&As. Also, no significant performance difference was observed between related and unrelated diversifications.

This study investigates intents of acquisitions in information technology industries. Mergers and acquisitions are a strategic decision at corporate-level and have been an important tool for a firm to grow. Plenty of firms in information technology industries have acquired startups to increase production efficiency, expand customer base, or improve quality over the last decades. For example, Google has made about 200 acquisitions since 2001, Cisco has acquired about 210 firms since 1993, Oracle has made about 125 acquisitions since 1994, and Microsoft has acquired about 200 firms since 1987. Although there have been many existing papers that theoretically study intents or motivations of acquisitions, there are limited papers that empirically investigate them mainly because it is challenging to measure and quantify intents of M&As. This study examines the intent of acquisitions by measuring specific intents for M&A transactions. Using our measures of acquisition intents, we compare the intents by four acquisition types: (1) the acquisition where a hardware firm acquires a hardware firm, (2) the acquisition where a hardware firm acquires a software/IT service firm, (3) the acquisition where a software/IT service firm acquires a hardware firm, and (4) the acquisition where a software /IT service firm acquires a software/IT service firm. We presume that there are difference in reasons why a hardware firm acquires another hardware firm, why a hardware firm acquires a software firm, why a software/IT service firm acquires a hardware firm, and why a software/IT service firm acquires another software/IT service firm. Using data of the M&As in US IT industries, we identified major intents of the M&As. The acquisition intents are identified based on the press release of M&A announcements and measured with four categories. First, an acquirer may have intents of cost saving in operations by sharing common resources between the acquirer and the target. The cost saving can accrue from economies of scope and scale. Second, an acquirer may have intents of product enhancement/development. Knowledge and skills transferred from the target may enable the acquirer to enhance the product quality or to expand product lines. Third, an acquirer may have intents of gain additional customer base to expand the market, to penetrate the market, or to enter a foreign market. Fourth, a firm may acquire a target with intents of expanding customer channels. By complementing existing channel to the customer, the firm can increase its revenue. Our results show that acquirers have had intents of cost saving more in acquisitions between hardware companies than in acquisitions between software companies. Hardware firms are more likely to acquire with intents of product enhancement or development than software firms. Overall, the intent of product enhancement/development is the most frequent intent in all of the four acquisition types, and the intent of customer base expansion is the second. We also analyze our data with the classification of production-side intents and customer-side intents, which is based on activities of the value chain of a firm. Intents of cost saving operations and those of product enhancement/development can be viewed as production-side intents and intents of customer base expansion and those of expanding customer channels can be viewed as customer-side intents. Our analysis shows that the ratio between the number of customer-side intents and that of production-side intents is higher in acquisitions where a software firm is an acquirer than in the acquisitions where a hardware firm is an acquirer. This study can contribute to IS literature. First, this study provides insights in understanding M&As in IT industries by answering for question of why an IT firm intends to another IT firm. Second, this study also provides distribution of acquisition intents for acquisition types.

This study examines the effects of the acquirer's experience on cross-border mergers and acquisitions(CB M&A) performance. We posit that various types of experience on M&A, including heterogeneity of experience, strategic alliance experience, first CB M&A, domestic and CB M&A experience may have an influence on the performance of CB M&A. The hypotheses are tested with multiple regression on global M&As made by Korean firms over the period of more than fifteen years. The empirical results indicate that firms with domestic M&A experience and the ones with CB M&A experience improve firm performance. Specifically, CB M&A experience more strongly and positively affects CB M&A performance. It also reveals that M&A experience and first CB M&A positively affect CB M&A performance. However, heterogeneity of experience negatively affects CB M&A performance and it has found no significant relationship between strategic alliance and firm performance. In addition, data show that the better explanation is an overall U-shaped relationship than a linear one between CB M&A experience and Performance. Overall, this study contributes to the literature on CB M&A by examining the effect of various types of experience such as heterogeneity of experience and alliance experience and offering a different explanation based on experience, more specifically, addressing the negative relationship between heterogeneity of experience and M&A performance.

SPAC(Special Purpose Acquisition Company) is the paper company that aims the merger of private company only, and introduced in Korea at 2009. Until 2013, 22 SPACs were listed, and 10 of them made successful mergers but rest were delisted. When IPO, range of the volume of public offerings were 20~30 billion won. After IPO, some SPACs showed extreme price movements, but on average their prices were below IPO prices 1 year later and near IPO prices 2 years later. Successful SPACs showed positive and significant 2.94% 25 days Cumulative Average Abnormal Return(CAAR) before the public announcements of merger and also showed positive and significant 10.60% 45 days CAAR around the general meetings of shareholders. I concluded that SPAC market were constrained by several regulations, so deregulation is needed for SPAC market activation.

A number of companies are considering for merger and acquisition (M&A) as one of business strategies for their growth and survival. However, many of them do not create the synergy they had sought, and failed M&A, often result in negative outcomes in terms of productivity, market share, profitability and turnover of qualified employees. There have been numerous research studies conducted to analyze the factors that determine the success and failure of M&A, and it has been found that with the increasing dependence of many companies on information systems, post-M&A IS (information systems) integration success has a critical effect on the success of M&A. However, there have been very few studies on post-M&A IS integration success, and most have been restricted to integration of IS organizations or physical information systems. In order to conduct a comprehensive research on the factors that affect the success of post-M&A IS integration, this study surveyed preceding researches on not only information systems but also strategic management, economics, finance, HRM (human resource management) and organization management. Based on the findings, a comprehensive and integrated model of the influential factors on post-M&A IS integration has been proposed. The proposed model categorizes the factors into perspectives of M&A, strategy, organization, HRM and IS, and provides an empirical evaluation of each factor on the success of IS integration based on comparative case studies.
