In event studies, the now standard window of a few days may miss relevant price movements if the market’s reaction to the news announcement tends to be slow or if the initial reaction tends to be partially or wholly undone afterwards. We propose a parsimonious hybrid of splines and Almon lags to detect and classify various patterns of post-event reactions spread over many periods. The scheme can interact with one or more event characteristics (like deal size), and the resulting non-linear model can be estimated via maximum likelihood (ML).In our application, we study the returns pattern that follows takeover announcements by two leading serial acquirers, AB Inbev SA and Heineken. Our method confirms the presence of a drop-and-recovery pattern as reported in Doan and Sercu (2021), but the amplitude of the pattern shows no link with deal size. This last finding is not in line with the view that the pattern reflects a rise in uncertainty that is slowly resolved (Malatesta and Thomson, 1985). 相似文献

Terrorist attacks occur mostly at public service-oriented sites. Consequently, their victims are likely to be customers. The present study explores how customers instinctively react toward the reality of terror in a matrix of 2 × 2 aspects concerning terror circumstances: temporal proximity (brief or long) and physical proximity (close or remote) from the terror event. In qualitative in-depth interviews, customers from France and Israel were requested to share their instinctive reactions and coping strategies when approaching hospitality (hedonistic) and transportation (utilitarian) services. Participants (N = 47) comprised customers having a protracted acquaintance with persistent terror threats. The analysis identified differences in reactions, subject to temporal and physical proximities. When terror attacks are physically close, customers’ emotions, cognitions, and behaviors undergo modification with time. However, when terror attacks occur at a location remote from the customer, customers’ emotions and cognitions, but not their behavior, change with time. These reactions were comparable for the two service contexts. Practical implications were elaborated to enable service establishments (i.e., hospitality and transportation) to design and manage their operations for the short and long term to assist customers in the difficult era of terror. 相似文献

This study investigates whether major USDA reports still provide important news to changing crop markets. The news component of each report, or market “surprise,” is measured as a difference between the USDA estimate and its private expectation in corn, soybeans, and wheat markets. Changes in the relevance of USDA information are assessed by examining changes in the magnitude of market surprises and shifts in the futures price reaction to these surprises, which isolates the impact of each report. The stable size of market surprises over time suggests that competition from alternative data sources has not reduced the news component of USDA crop reports. Increasing price reaction to most reports, including those facing competition from alternative information sources, suggests that value of public information may be enhanced in uncertain markets affected by structural changes. 相似文献

We examine differences in stock price, option volatility, and litigation reactions to restatement announcements that are associated with a material weakness (MW) disclosure. Contrasted with restatements that are not associated with any MW disclosure, our analyses reveal that firms that announce both a restatement and an associated MW experience significantly more negative market returns, greater implied volatility, and higher likelihood of class action lawsuits. Separating the restatements into timely reporters, where the MW precedes the restatement, and non‐timely reporters, where the MW is concurrent with or follows the restatement, we find that timely reporters experience more negative returns at the time of the restatement, relative to non‐timely reporters, suggesting that investors perceive the early MW disclosure to signal more pervasive control‐related problems. Interestingly, we find that timely and non‐timely reporters are equally likely to be sued, consistent with the argument that wrongdoing (through either a timely or non‐timely MW disclosure) provides stronger grounds for establishing scienter. However, timely reporters appear to secure more favorable litigation outcomes: they face higher likelihood of lawsuit dismissals and pay much lower settlements, compared to non‐timely reporters. Overall, our evidence provides new insights into how market participants incorporate information about internal control weaknesses into their perceptions regarding the economic implications of financial restatements, and financial reporting quality. 相似文献

This paper examines the cumulative market reaction to the events related to deferral of internal control audit requirement under the Sarbanes-Oxley Act of 2002 and its elimination under the Dodd-Frank Act of 2010 for nonaccelerated filers (small firms). We document that small firms experienced negative cumulative abnormal returns around these events; and the differences between the cumulative abnormal returns for small firms and the two control groups (accelerated and large accelerated filers) were negative and significant at the 1% level. These results support the notion that market participants value the reliability of financial information irrespective of the firm size. Within the small firms, we find no firm characteristic significantly explains the market reaction to the events considered. That is, all small firms lost market value in reaction to the events that delayed and eliminated their internal control audit requirement. 相似文献

This paper aims at decteting what drove the adoption of austerity policies over the period 2010–16 in a panel of 28 European countries. Austerity is identified by year increases in the ratio between the structural primary balance and potential GDP. By means of principal component factor analysis we select the aggregate factors that might affect austerity, namely (i) fiscal consolidation (correction of high deficits and debts), (ii) market discipline (high sovereign spreads, low ratings), (iii) rule-based fiscal discipline (compliance with the Eurozone rules), and macroeconomic stabilisation (consideration for the cyclical position of the economy). Then we estimate a dynamic panel model with the system-GMM method. Results show that the most important contributions to austerity are provided by the market discipline and fiscal consolidation factors together with Excessive Deficit Procedures, with no significant role played by concomitant macroeconomic conditions. Overall, governments complied with orthodox fiscal principles and rules. 相似文献

Aims: This study aimed to estimate the cost of platelet transfusion in patients with chronic liver disease (CLD)-associated thrombocytopenia undergoing an elective procedure in the United States.Materials and methods: The study was conducted in two parts: development of a conceptual framework identifying direct, indirect and intangible costs of platelet transfusion, followed by the estimation of the total cost of platelet transfusion in patients with CLD-associated thrombocytopenia before an elective procedure in the United States using the conceptual framework and cost data obtained from a literature search. The cost of the entire care required to raise a patient’s platelet count before the procedure was considered.Results: The final conceptual framework included the costs of generating the supply of platelets, the platelet transfusion itself, adverse events associated with platelet transfusion and refractoriness to platelet transfusion. When costs were accounted for in all the framework cost categories, the total direct cost of a platelet transfusion in a patient with CLD and associated thrombocytopenia was estimated to be in the range of $5258 to $13,117 (2017?US dollars) in the United States. The largest portion of costs was incurred by the transfusion event itself ($3723 to $4436) and the cost of refractoriness ($874 to $7578), which included the opportunity cost of a delayed procedure and subsequent platelet transfusions with human leukocyte antigen-matched platelets.Limitations and conclusions: Although we were unable to include all cost components identified in the conceptual framework in our total cost estimate, thus likely underestimating the true total cost, and despite the data gaps and challenges limiting our estimate of the full cost of a platelet transfusion in patients with CLD-associated thrombocytopenia undergoing an elective procedure in the United States, this study outlines a comprehensive conceptual framework for estimating the cost elements of a platelet transfusion in these patients. 相似文献

This study examines whether market participants react to the announcements of corporate governance ranking exercises. As a regulatory innovation, the Financial Supervisory Commission in Taiwan initiated and administered two ranking exercises, one in 2015 and the other in 2016, on all publicly listed companies. Adopting anchoring-and-adjustment theory, the study predicts that market participants will react strongly to the second announcement if the ranking obtained in the second exercise turns out to be better than the ranking in the first round. Employing an event study methodology, the study shows that market participants react positively and significantly to firms ranked in the top 50% in the second corporate governance exercise. Their reactions to the announcement are even stronger among those that did not list in the top 20% in the first exercise, but made it into the top 50% in the second one. Overall, our analyses support that anchoring-and-adjustment theory effectively explains market participants’ behaviour. Since the monitoring of the board of directors and investors may not effectively mitigate the potential moral hazard committed by family owners/executives, our empirical evidence demonstrates that a ranking exercise probably can be employed to supplement routine corporate governance disclosures made in annual reports, in order to strengthen the check-and-balance mechanism and reduce the risk of principal–principal conflicts. In conclusion, we discuss the implications of the research findings and propose directions for future studies. 相似文献

股权再融资往往意味着企业存在大量的融资需求,而实践中普遍存在的股权再融资后立即现金分红的现象有悖于募集资金的优序使用原则。基于此,本文从管理层自利视角出发,在对企业股权再融资后现金分红的行为偏好检验的基础上,进一步选取管理层薪酬增长率和企业股权质押活动作为管理层自利程度的代理变量,探索企业股权再融资后现金分红倾向的边界条件,为该行为背后的代理动机提供证明。基于2007~2017年所有A股上市公司样本,研究发现,企业的确存在股权再融资后立即现金分红的行为倾向;而较低的管理层薪酬增长率和企业股权质押活动会加剧企业股权融资对现金分红的促进作用。进一步研究发现,企业股权再融资活动会给现金分红带来消极的市场反应。上述研究结果表明,管理层自利是股权再融资的重要推动因素,而这一行为会给企业利益造成损害。 相似文献
