强调事项段、审计意见变通和投资者市场反应

本文认为,我国投资者对非限制性强调事项和限制性强调事项的无保留审计意见的市场反应没有明显区别,但是对非限制性强调事项的无保留审计意见有显著的负反应。这说明我国投资者对比较清晰和易于理解的非限制性强调事项能作出判别,而对比较复杂的限制性强调事项缺乏辨别力,在不存在市场和投资者监督的压力下,必然会增加注册会计师利用限制性强调事项改变审计意见的动机,因此有必要通过政府监管手段来规范注册会计师出具带强调事项段的无保留审计意见的行为。在投资者信息识别能力较低的情况下,2003年和2006年审计报告准则对强调事项的内容加以限制是非常及时和必要的,通过对强调事项的严格限制可以约束注册会计师审计报告行为,抑制注册会计师利用强调事项段变通审计意见。     

定向增发预案公告市场反应及其影响因素研究——基于深圳证券交易所上市公司数据的分析

自股权分置改革实施以来,定向增发成为中国上市公司资本市场权益再融资的重要方式之一。通过运用事件研究法对2006年—2007年实施定向增发的深市上市公司董事会预案公告日前后超额收益变化的分析,发现增发规模、机构投资者认购比例是影响预案公告后公司股票超额收益的主要因素;同时还发现在定价基准日之前20个交易日内定向增发公司股价弱于市场表现,存在负的超额收益。     

银行信贷顺周期性的微观行为特征与优化控制——基于青岛市大数据平台

银行信贷管理具有明显的周期性,尤其是在经济下行期银行的＂避险＂行为比较突出。基于青岛市大数据平台,本文对经济下行期银行信贷管理行为进行研究,力图总结出银行的微观行为特征。本文认为银行的风险敏感度和预见度并不高,行为多表现出短期应激性,主要表现是前置性强势和风险处置弱势的双重特征,并且银行在对待周期性行业和非周期性行业方面呈现出较大差异。银行的行为特征有其内在组织和市场根源因素,通过对根源因素开展可控性分析,对其优化控制可以缓解银行信贷的顺周期性。     

新冠肺炎疫情冲击下企业现金持有的预防价值研究

最近爆发的新冠肺炎疫情牵动着亿万民众的心,面对突如其来的疫情,企业资金面临着巨大压力。企业持有现金主要源于预防和交易动机,然而预防动机的特性决定了其在企业正常经营状态下难以直观体现,因而目前鲜有研究对企业现金持有的预防价值进行直接检验。本文以新冠肺炎疫情事件的冲击为研究切入点,通过考察不同现金持有水平的企业在面临危机冲击的市场反应,发现企业现金持有水平与事件窗口期内的累计超额收益率呈显著正相关关系,从而为现金持有的预防价值提供了更为直接的经验证据。而且,当公司受疫情冲击程度越大时,二者之间正相关关系越强。进一步发现,企业现金持有的预防价值在企业现金流压力大以及外部融资环境较差时更加凸显。本研究丰富了已有关于现金持有预防价值的相关文献,并对政府与企业应采取何种举措以应对突发事件具有一定的启示。     

Does religiosity enhance the quality of management earnings forecasts?

This study investigates whether firms located in areas with higher levels of religiosity disclose higher-quality management earnings forecasts than do other firms. Using a US sample of 4,655 firm-year observations over the period 2001 to 2014, we find that firms headquartered in counties with higher proportions of religious adherents issue earnings forecasts that are less optimistically biased and that the effect of religiosity is concentrated in firms with weak monitoring mechanisms. We also find that religiosity mitigates pessimistic bias in management earnings forecasts, but only for those issued by firms operating in low litigation industries. This result suggests that when the litigation risk is high, both ethicality and risk aversion are at work and their competing effects likely offset each other. Additionally, we document that forecasts issued by firms in more religious areas trigger stronger stock price reactions than those issued by other firms and that the effect is limited to forecasts containing optimistic bias. Overall, our results show that religiosity enhances the quality of management earnings forecasts, but the effect varies based on different conditions.     

Are Interventions Self Exciting?

The time pattern of official interventions on the foreign exchange market exhibits periods of intense activity followed by long spells of inaction. In this paper, we examine whether the time interval between successive intervention matters for future interventions. To capture the properties of intervention duration an ACD model is used. The data are daily observations of interventions by the Federal Reserve, the Bundesbank and the Swiss National Bank. The evidence finds that the intervention duration is highly persistent and that the hazard is time dependent.     

Asymmetric Trading Costs Prior to Earnings Announcements: Implications for Price Discovery and Returns

We show that the cost of trading on negative news, relative to positive news, increases before earnings announcements. Our evidence suggests that this asymmetry is due to financial intermediaries reducing their exposure to announcement risks by providing liquidity asymmetrically. This asymmetry creates a predictable upward bias in prices that increases preannouncement, and subsequently reverses, confounding short‐window announcement returns as measures of earnings news and risk premia. These findings provide an alternative explanation for asymmetric return reactions to firms' earnings news, and help explain puzzling prior evidence that announcement risk premia precede the actual announcements. Our study informs methods for research centering on earnings announcements and offers a possible explanation for patterns in returns around anticipated periods of heightened inventory risks, including alternative firm‐level, industry‐level, and macroeconomic information events.     

Consequences of the Treasury Single Account Policy on the Wealth of Nigerian Commercial Banks’ Shareholders

We examine the impact of the Nigerian government’s Treasury Single Account (TSA) policy to withdraw the funds of Ministries, Departments and Agencies from commercial banks. Following the economic policy uncertainty theory, we use an event study methodology to measure the impact of the TSA policy on the shareholders’ wealth. Our results reveal that the announcements and subsequent final implementation of the TSA policy caused negative abnormal returns and losses on the wealth of the commercial banks’ shareholders. This article contributes to the literature on stock market reaction to policy announcements and the unintended consequences government policy can have in an emerging economy.     

Short‐selling pressure and last‐resort debt finance: evidence from 144A high‐yield risk‐adjusted debt

This study examines why non‐financial publicly traded firms knowingly issue wealth destroying Rule 144A debt, which is associated with a negative announcement return and a higher yield. We provide a plausible ‘demand‐side’ explanation (i.e. last‐resort debt financing) for the motivation for issuing such debt. We also provide evidence as to what drives this negative reaction. Our findings suggest that the negative market impact is mainly driven by short‐selling pressure from convertible bond arbitrageurs.     

基于公司治理视角的媒体监督机制研究

基于公司治理视角对媒体监督机制的研究,不仅有助于扩展法律外制度在公司治理中的应用,而且为管理学、传播学与行为心理学的相互作用研究建立了桥梁。本文先回顾了媒体监督机制的治理效用的相关经验研究,进而通过分析媒体监督的内在作用机理,指出信息挖掘能力、媒体偏度、路径有效性、高管私利与风险偏好这＂五因素＂共同决定了媒体监督治理功能的发挥。
