中期财务报告自愿审计的动机和市场反应分析——基于中国上市公司的经验数据

作为外部治理机制的审计是公司信息披露质量的重要保证,目前法规对上市公司中期财务报告的审计并无强制性法规要求,许多上市公司选择中期财务报表自愿审计,其行为是一种主动传递信息的过程。本文通过对我国上市公司2007至2010年证券市场自愿中报审计的经验数据分析,对公司自愿中报审计的动机和市场反应进行了实证研究。研究发现:公司中期财务报表自愿审计与公司的成长性和公司规模显著相关,且公司的财务状况和股权性质对公司的自愿审计有一定影响;同时,市场对上市公司中期财务报告自愿审计行为有一定的正面反应,但这种反应效力不足,且持续力较低。     

盈余重述的市场反应及其影响因素研究——基于我国2004-2010年数据的经验分析

本文以2004-2010年盈余重述为样本,检验了我国盈余重述的市场反应及其影响因素。根据重述披露的时点选择特征,首次提出聚合重述和分离重述概念。研究发现,年报的利好消息或非利好消息对盈余重述负面影响的"抵减效应"或"加剧效应"都十分显著;剔除年报影响的分离重述的市场反应显著为-3%。研究还发现,相对于被动重述,主动重述被认为是"主动说真话"的表现,具有"坦白从宽"的效果;重述追溯调整的幅度、公司盈利能力、财务风险和债务水平,都会显著影响重述公告时的市场反应程度。     

竹浆纤维针织物的耐磨性研究

通过实验研究了7种不同混纺比的纬平针组织竹浆纤维针织物的耐磨性。应用马丁代尔实验方法和实验仪对这些针织物的耐磨性进行了测定。根据织物在摩擦转数为5 000,7 500,10 000,15 000和25 000的质量损失率来评价织物的耐磨性。通过对实验数据的统计分析,得出7种织物的耐磨性在不同的摩擦转数都存在着显著性差异;织物的质量损失与摩擦转数之间存在着重要的、显著的正相关关系,织物的质量损失随着摩擦转数的增加而加大;纱线细度对织物耐磨性具有较大的影响。     

企业科技创新行为中的阻力与化解

企业科技创新行为的阻力源中,企业的管理者、基层科技人员与组织因素这3个阻力源产生的原因是不同的,而旧有“个人契约”的修改是化解管理者与基层科技人员阻力的有力工具。但是在“个人契约”修改的过程中,企业领导者对创新行为的态度、表现,领导者与企业成员之间的沟通与动员,对企业成员的教育与培训等等措施的实施,同样是十分重要的。     

Asset Prices as Indicators of Euro Area Monetary Policy: An Empirical Assessment of Their Role in a Taylor Rule

This paper estimates forward-looking and forecast-based Taylor rules for France, Germany, Italy, and the euro area. Performing extensive tests for over-identifying restrictions and instrument relevance, we find that asset prices can be highly relevant as instruments in policy rules. While asset prices improve Taylor rule estimates, different assets prove most relevant across countries and this result could be seen as complicating the tasks of the European Central Bank. Encompassing tests show that forecast-based outperform forward-looking Taylor rules. A policy implication is that central banks ought to release their own forecasts and the basis upon which they are generated.

变革前消极非正式信息对员工的影响机制研究

组织变革前会有相关的非正式信息,这些信息影响员工对变革的认识。文章探索变革前消极非正式信息量对员工变革抵制意愿的影响,以及员工变革抵制意愿随时间推移的变化,信息频率与尽责性对员工变革抵制意愿变化的调节作用。基于159位员工调查数据的多层次线性增长模型分析表明：消极非正式信息量显著增加员工的变革抵制意愿,但这种抵制意愿随时间推移而显著衰减;消极非正式信息频率与尽责性对员工变革抵制意愿随时间衰减有三维调节作用：在低信息频率下,低尽责性员工的变革抵制意愿随时间衰减更快。研究结果对组织变革有一定理论和实践意义。     

A tactical retreat? Conceptualising the dynamics of European grocery retail divestment from East Asia

The internationalisation of the firm is a highly dynamic process, in which periods of investment and expansion intermingle with periods of divestment and retrenchment. Academic research to date has focused on identifying the reasons for and the processes of divestment. Empirical studies either evidence generic pressures or provide case studies of specific incidents. There few longitudinal studies of international divestment, consequently the dynamic interactions between host market, home market and firm level factors, and how the institutional context changes over time is underplayed. This paper seeks to rectify this gap in our understanding.We explore the rationale and evolving dynamics of European grocery retail divestment in East Asia over a thirty year period. Taking an inductive approach and drawing on analysis of contemporary narratives drawn from company documentation, trade journals, newsfeeds and market reports, three phases can be identified characterised by specific factors and combinations of factors which intersect to provide the key pressures and stimuli for divestment. We conclude that at different time periods, different internal and external contextual influences manifest themselves through different priorities within the firm’s strategy – marked by a switch from local (host) market, to regional, to global firm-centric considerations. Longitudinal analyses allow a greater recognition of this dynamic interplay of factors, and the changes in these relationships, and provides a more nuanced understanding of the international divestment process.     

Modelling multiperiod patterns in stock-market reactions to events,with an application to serial acquisitions

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).     

The impact on stock prices of deferral and elimination of internal control audit requirement for small firms

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.     

Material weakness disclosures and restatement announcements: The joint and order effects

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.
