The Effect of Media Coverage on the Pricing of Seasoned Equity Offerings

This paper examines the role of media coverage and investor attention on the outcomes of seasoned equity offerings (SEOs). I use an archive of Thomson Reuters news articles to proxy for firm visibility and investor attention. I find that the volumes of news articles prior to the offerings are positively associated with the offer price discounts of SEOs. Furthermore, the volumes of news articles are negatively associated with the cumulative abnormal returns three days around the SEOs. I conclude that the costs of equity increase with media coverage prior to SEOs. Overall, the evidence is consistent with the hypothesis that media coverage affects investors' information processing in SEOs. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

Initial Margin Requirements, Volatility, and the Individual Investor: Insights from Japan

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.

我国证券纠纷调解机制的完善和金融申诉专员制度合理要素的借鉴

我国新修订的《证券法》于2020年3月1日正式施行。作为资本市场根本法规,《证券法》新增第六章"投资者保护"可谓亮点之一,其中第94条规定"强制调解制度"在诉讼和仲裁之外为投资者提供了新的维权路径,加强对投资者的事后保护。但目前我国证券纠纷调解机制仍有诸多问题,例如法律条文碎片化、调解协议刚性不足、调解衔接机制不完善、调解机构体系混乱、监督机制不力等,这些弊病从根本上严重影响证券纠纷调解机制的制度设计和程序运行。本文拟通过分析英国金融申诉专员制度的成熟经验,为我国证券纠纷调解机制的完善和发展提出优化路径。

Ownership concentration and bank risk: international study on acquisitions

This paper explores the effects of different types of bank ownership concentration on changes in bank risk during acquisition years. Using multi-country data from 2000 to 2006, during which market failures caused by various crises and government interventions are less influential to acquisition decisions, we collect 505 banking acquisition deals from 23 countries to examine which type of ownership concentration (such as financial intermediary, capital investor, non-financial, and state ownership) brings larger changes to an acquirer’s risk from pre-acquisition year to post-acquisition year (including non-performing loans, capital adequacy ratio, loan loss reserve, and credit rating). The empirical analyses show that acquirer banks with a concentration of shares owned by financial intermediaries and non-financial firms experience larger risk changes during acquisition years. In contrast, the risk changes of acquirer banks with a concentration of capital investors and state ownership are lower. Robustness checks from the random effect estimation, instrumental variables model, reverse causality, and different subsamples of (non-)U.S. or different levels of regulation enforcement confirm these results.     

机构投资者与个人投资者非理性行为差异研究

机构投资者与个人投资者是证券市场的重要组成部分,其非理性程度直接影响着市场的健康稳定。本文基于有情境元素的问卷调查,构建包含投资者类别为自变量,年龄和性别为控制变量,16种常见非理性行为为因变量的分析框架,实证检验机构投资者与个人投资者非理性行为差异。结果表明,中国机构投资者与个人投资者都存在严重的非理性行为;相比机构投资者,个人投资者非理性程度更为严重;机构投资者与个人投资者在偏好逆转、证实性偏差、沉没成本、模糊厌恶、处置效应和损失厌恶方面存在显著差异。本研究为投资者防范非理性行为提供建议,为市场稳定发展提供参考。
