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.

Management Changes

Logistics researchers often want to understand how particular management changes or external factors influence a firm. While this can be accomplished using operational or survey data, the authors outline an alternative approach using the event study method where inferences are made with the estimated magnitude and direction of abnormal returns. The calculated abnormal returns can be used as a dependent variable in a cross-sectional regression to understand which managerial decisions may affect these outcomes. As the method remains little used by logistics researchers, the authors outline key assumptions and design considerations. They review recent articles and provide suggestions for logistics researchers improve the rigor of their research designs. This article aims to provide an overview of the method for logistics and supply chain researchers with a focus on developing the capability to design an effective study and to evaluate research articles to assess methodological weaknesses that may lead to untrustworthy results.

The Prestige

This study explicitly rejects the prima facie proposition that the top-tier investment banks are capable of delivering supernormal value creation to the shareholders of a REIT acquirer in a corporate acquisition. Using the event study method, we find that REIT acquirers advised by market-leading investment banks suffer an average cumulative abnormal return of −4.41% following the M&A announcement, whereas REIT acquirers advised by non-top-tier investment banks only suffer an average cumulative abnormal return of −1.49%. The evidence shows that the contemporary practice of employing investment banks based on the prestige of the advisory firms could potentially result in value-destroying M&As for the REIT acquirers.

<p>Goals of the research to analyze whether occurred abnormal return of ASIAN Games phenomena and see how investors react to the big ASIAN Games 2018 event in Indonesia. . This reseach uses a sample of companies included in the hotel, restaurant and tourism sub-sector on the Indonesia Stock Exchange (IDX) during the observation period, based on the purposive sampling method which obtained 22 companies and used the event study method. There is a significant abnormal return but not on the phenomenon of the Asian Games 2018. This shows that investors still wait and see to the organization of the Asian Games in 2018. No difference of abnormal return before and after the Asian Games 2018. This is because, as investors look to the many tourists who have started to flock to Indonesia before the Asian Games in 2018 took place.<em></em></p><p><strong><em></em></strong><em><br /></em></p>

Event Study Methodology

The objective of this study is to assess the share price reactions to smoking ban fatwa on Indonesia tobacco’s company. We expect that the smoking ban fatwa in the world’s largest Muslim population will hit the tobaccos industry revenues, lower tobacco’s company profit and eventually affect the share price of those firms. We use event study methodology and standard market model to calculate abnormal returns of the tobacco’s firms related to the news of smoking ban fatwa. Our study failed to find a statistically significant effect of smoking ban fatwa on tobacco’s firm stock market return. It suggests that the investors do not see the fatwa as a factor that may control the tobacco consumption in Indonesia – thus it may not affect the tobacco’s firm revenues and profit in the future

Event Study Method

The event study method allows researchers to examine the importance of an event to firms based on the magnitude and direction of abnormal returns, and then use these results in a cross-sectional regression to understand which managerial decisions may affect these outcomes. While the method has been heavily used in some disciplines, in-management research and logistics research, in particular, the method remains little used and is often used with little thought to key assumptions and design considerations. This chapter aims to provide an overview of the method for logistics and supply chain researchers with a focus on developing the capability to design an effective study and to evaluate research articles to determine possible weaknesses.

This paper investigated how food and beverage (F&amp;amp;B) stocks react to COVID-19. The event study method was applied to four events including the first and second events, were the first COVID-19 positive patients detected in the largest and second-largest economic center of Vietnam. The third and fourth events are related to strong measures to prevent the spread of COVID-19: the nationwide lockdown at the beginning of the second quarter of 2020, and the lockdown of Danang at the beginning of the third quarter of 2020. The results show that the reaction of F&amp;amp;B stock prices to events supports the semi-strong form of efficient market theory. The strong and lasting negative reaction of F&amp;amp;B stocks to the first event can be explained by surprise (first case in Vietnam) and Hochiminh city’s economic engine driving role in the development of Vietnam’s economy. The study finds that heuristic decision-making from nationwide lockdowns (suppression of supply chains during lockdowns) can explain the sub-sector of farming-fishing-ranching products reacted more strongly to the lockdown event in Danang. Based on the research results, this paper provides some policy implications for managers and notes for securities investors.
