Description
Firms are increasingly being held accountable for the unsustainable actions of their suppliers. Stakeholders, regulatory agencies, and customers alike are calling for increased levels of transparency and higher standards of corporate social responsibility (CSR) performance for suppliers. While it is apparent that supplier performance is important, it remains unclear how the stock market weighs the CSR performance of a supplier relative to that of a focal firm. This dissertation focuses on whether these relative differences exist. In addition to capturing the magnitude of the difference in market impact between focal firm and supplier CSR events; I analyze the ways in which these differences have changed over time. To capture this evolution, CSR events ranging over a period from 1994 to 2013 are examined. This research utilizes an event study methodology in which the announcement of over 2,300 CSR events are identified and analyzed to determine the subsequent stock market reaction. I find that while the market evaluated negative supplier CSR events less harshly than events occurring at the buying firm in the early years of the sample, by the turn of the millennium this “supplier discounting" had disappeared. The analysis is broken down by CSR event "type". Findings demonstrate that negative CSR events, particularly those revolving around worker or customer safety, generate the most significant abnormal return. The findings of this dissertation produce valuable managerial insights along with interpretation. Resources are scarce, and understanding where a firm might best allocate their resources to avoid financial penalties will be valuable information for corporate decision makers. These findings present clear evidence that some of these resources should be allocated to supplier CSR performance, not just towards the CSR performance of the focal firm.

Description
The pharmaceutical industry is heavily regulated. This regulation results in a high number of recalls in this industry compared to other industries. The pharmaceutical industry is subject to high regulation because of the harmful effects pharmaceuticals can have on consumers. In this paper I examine the valuation effects that a drug recall has on both the recalling firm and the recalling firm's rivals. I perform an event study analysis on the data. I show that there exists a statistically significant negative effect for a drug recall on the recalling firm's market value immediately surrounding the announcement. Additionally, there is a statistically significant positive effect for a drug recall on the recalling firm's rivals after the announcement.

Description
Every year, major companies buy Super Bowl advertisements (‘ads’) to fuel growth through the creation of brand awareness among a large, diverse audience. Although measuring the effectiveness of these marketing tactics is difficult, evaluating the abnormal returns (‘alpha’) of company stocks in the five days following the Super Bowl is effective because it provides insight into how actual returns compare to expected returns (calculated using data from the preceding 250 days). Analysis of a comprehensive sample, which includes all Super Bowl ads for public companies between the years 2015 and 2019, accurately demonstrates the relationship between these returns, illustrating the effectiveness of this type of marketing. To account for variation resulting from different inputs in different financial models, it is important to evaluate alpha based on several, reputable models of expected return to best capture the result. In this study, alpha will be analyzed using the Capital Asset Pricing Model (‘CAPM’) and the Fama and French 3 and 5 factor models. Although the ideology that increased marketing improves stock returns through brand awareness suggests a positive alpha, these models all indicate a statistically significant negative alpha for large, public companies who bought Super Bowl ads over the past five years. Therefore, actual returns, on average, are lower than projected returns for the evaluated five-day window following the Super Bowl. In examining alpha and statistical significance according to these financial models, this thesis will explore different market factors that may explain this counterintuitive result, primarily focusing on the investors’ opinions about this type of marketing. Therefore, in researching various discrepancies contributing to the negative alpha result, this study will accurately assess the effectiveness of Super Bowl advertising in terms of stock performance.

Description随着我国资本市场的快速发展，连续并购成为上市公司实现市值提升的重要策略，然而对于连续并购是否能实现有效价值创造和市值增长，国内外文献研究均没有一致的结论。本文研究连续并购对上市公司短期和长期绩效的影响，并探究管理层过度自信现象和学习效应、公司股权性质和并购交易特征等对结果的影响，就企业如何更好的发挥连续并购价值创造功能，避免潜在风险等方面提出相应建议。利用国泰安（CSMAR）并购重组数据库, 本文以2010-2017年A股公司为研究样本，通过事件研究法发现，连续并购能带来正的超额收益(CAR)，但当连续并购阶次达到4阶时，市场反应明显变负。CAR随着阶次递增呈现下降趋势，证明了连续并购的财富递减效应。进一步地，本文发现首次并购成功带来的过度自信会导致高阶次并购绩效不断下降；管理层未经过充分学习和准备就进行的并购，会伤害公司短期绩效，并且可能阻碍公司更高阶的并购事件的发生。结果证明了管理者过度自信假说在A股市场的适用性，以及组织学习理论的部分解释能力。控制并购交易等因素后的多元回归结果和前述发现一致。
接下来，本文采用多元回归对连续并购长期绩效影响进行实证检验。在经营绩效方面，连续并购行为短期内不会产生明显负面影响，但随着并购的完成和新业务的开展，连续并购对经营业绩的负面影响逐渐凸显并显著，结果证实连续并购对公司长期经营业绩是有害的。交易特征变量、公司治理结构和财务状态一定程度上能够改善公司长期业绩。对于长期市场估值倍数，本文发现连续并购能够显著提升公司的市场估值倍数， 并且该正面影响随着并购的完成和新业务的开展不断增强。进一步探究发现，连续并购对经营绩效的负面影响只存在于国有企业，而连续并购对市场估值倍数的提升作用只存在于私有企业，从而解释了连续并购后经营绩效和市场化估值倍数结果相悖现象的出现。基于本文发现，文章最后向上市公司管理层的并购决策提出了相应建议。
