The Impact

Differentiation of collusive and efficiency-based synergies in horizontal mergers has proven difficult. The authors propose a theory-backed methodological approach to classify mergers that yields greater information on merger types and merger effects. Moreover, the methodological approach distinguishes between mergers characterized largely by collusion-based synergies and those characterized largely by efficiency-based synergies. Crucial to the proposed method is that it considers the impact of merger events not only on merging firms, as is common in the literature, but also on non-merging rivals. The authors demonstrate how the proposed approach clarifies the nature of merger activity through an event-study procedure based on stock market data on samples of large horizontal mergers drawn from the US and UK (an Anglo-American sub-sample) and from the European continent the authors demonstrate how the proposed schematic clarifies the nature of merger activity.

Event Study Method

Purpose Celebrity endorsement advertising receives increased attention in the relevant literature. Approaching from the abnormal stock market return perspective, the purpose of this paper is to investigate the potential risks and expected profit associated with celebrity endorsement. The factors that are included in this investigation are the attributes relating to celebrities and the endorsed firms. Design/methodology/approach Data were collected from over 300 firms that use celebrity endorsements and are listed in two of the biggest stock exchanges in China. The study uses the event study method to analyze the proposed relationships. Findings Some of the findings in the current study are consistent with or contrast to those in previous research. Specifically, this study finds that the celebrities’ demographics such as age and gender have little influence on financial return of the endorsed firm. However, investors respond rather negatively toward using actor celebrities to endorse a product or a brand, especially for high-tech products. The match-up endorsement has a positive effect on the firm’s abnormal return. Research limitations/implications The current study has implications for the relevant literature and practitioners. Very few studies have used stock market return to measure celebrity endorsement effectiveness. This study provides insights into the influence of various factors associating with celebrities and the endorsed firm, extending the celebrity endorsement research into a broader domain. In particular, this study has practical implications for firms that have used or intend to use actor celebrity endorsement. Originality/value This study is the first to use event study method to comprehensively analyze influence of attributes relating to both the celebrities and the endorsed firms in China on stock market return.

Event Study Method

This study attempts to explore whether and how stock market responds to industrial accidents. We employ the event study method to look into the responses of stock markets to 83 accidents experienced by various listed companies in China, and explore how industrial accidents influence stock market in the different markets. Findings imply that the stock market shows negative reaction with respect to these accidents. However, as time goes by, the market reaction tapers off. In the bear market, the negative market reaction was highly significant. Small-sized companies, in comparison with other companies, have a most significant reaction to accidents and they also have the worst ability to recover from accidents. The findings of this study can help the investors to better understand how the stock market reacts to the industrial accidents in different market environments and under other conditions.

The Impact

This paper examines the abnormal returns in merger withdrawals in Australia, especially distinguishing the market response between private and public targets. We also study the determinants of those abnormal returns, including the method of payment and the impact of financial crisis periods. Using the event study method, we document that in the Australian context, the announced withdrawal of mergers involving private targets creates significantly negative valuation effects in comparison with the valuation effects in withdrawal of mergers involving public targets. We also find that a financial crisis period strongly affects abnormal returns of merger withdrawals. However, the method of payment does not have any impact on the abnormal returns.

This paper aims to analyze the efficient stock market hypothesis as responsive to American Presidential Election, 2016. The meta-analysis has been done combining content analysis and event study methodology. The all major newspapers, news channels, public polls, literature and five important indices as Dow Jones Industrial Average (DJIA), NASDAQ Stock Market Composit Indexe (NASDAQ-COMP), Standard & Poor's 500 Index (SPX-500), New York Stock Exchange Composite Index (NYSE-COMP) and Other U.S Indexes-Russell 2000 (RUT-2000) are critically examined and empirically analyzed. The findings from content analysis reflect that stunned winning of Mr Trump from Republican Party worked as shock for American stock market. From event study, findings confirmed that all the major indices reflected a decline on winning of Trump and losing of Ms. Clinton from Democratic. The results are supported empirically and practically through the political event like BREXIT that resulted in shock to Global stock index and loss of $2 Trillion.
