Divergence of Cash Flow and Voting Rights,Opacity, and Stock Price Crash Risk: International Evidence

This study investigates whether and how the deviation of cash flow rights (ownership) from voting rights (control), or simply the ownership‐control wedge, influences the likelihood that extreme negative outliers occur in stock return distributions, which we refer to as stock price crash risk. We do so using a comprehensive panel data set of firms with a dual‐class share structure from 20 countries around the world for the period of 1995–2007. We predict and find that opaque firms with a large wedge are more crash prone than opaque firms with a small wedge. In addition, we predict and find that the positive relation between the wedge and crash risk is less pronounced for firms with more effective external monitoring and for firms with greater growth opportunities. The results of this study are broadly consistent with Jin and Myers’s theory that agency costs, combined with opacity, exacerbate stock price crash risk.     

经济政策不确定性、意见分歧与股价崩盘风险

基于中文媒体构建的中国经济政策不确定性指数,研究经济政策不确定性对股价崩盘风险的影响效果和机制。结果显示:经济政策不确定性的提高会显著加剧股价崩盘风险,这表明经济政策不确定性是崩盘风险的诱因之一。通过对影响机制检验发现,经济政策不确定性对股价崩盘风险的正向作用,随着投资者意见分歧的增加而加强。在宏观经济良好时期,非国有股权和规模较大的企业,经济政策不确定性并未明显加剧股价崩盘风险,甚至起到了缓解股价崩盘风险的作用。     

财务重述、管理层权力与股价崩盘风险：来自中国证券市场的经验证据

股市震荡引发投资者和监管层对股价崩盘风险的关注。从财务重述背后所反映的财务信息质量低下和公司治理失效出发,探讨其对股价崩盘风险的影响,结合管理层权力这一影响组织行为和产出能力的代理人特征,探讨其对财务重述与股价崩盘风险之间关系的影响。研究结果表明：相比未发生财务重述的公司,发生了财务重述的公司的股价崩盘风险明显更高;进一步纳入代理人特征———管理层权力后,发现代理人的这一特征对上述关系有明显的促进作用。     

股吧评论、分析师跟踪与股价崩溃风险——关于模糊信息的信息含量分析

东方财富股吧等股票论坛日渐活跃,反映了投资者对获得上市公司真实、完整、及时信息的强烈需求。尽管股吧有助于促进信息传播,但仍是非正式的信息发布平台,股吧评论本质上是一种模糊信息。为探明股吧评论的信息含量,本文以2012—2017年A股上市公司为研究样本,研究股吧评论对股价崩溃风险的影响,以及同样属于模糊信息的分析师跟踪在这一过程中可能产生的作用。实证结果表明,股吧评论分歧越小,股价崩溃风险越大,并且分析师跟踪人数和研报数量在上述影响过程中发挥中介作用。研究结果有助于厘清股吧评论影响股价崩溃风险的路径和机理,既丰富了股价崩溃风险成因的研究,也揭示了股吧评论、分析师跟踪等模糊信息的信息含量。     

基于制度环境视角的非效率投资与股价崩盘风险研究

研究宏观层面的治理因子对企业非效率投资的调节作用,进而研究价格崩盘的成因。发现：较高的市场化进程、较低的政府干预程度和完善的法治环境都有助于抑制由非效率投资行为引发的股价崩盘风险。进一步的研究表明,企业非效率投资主要由代理成本而非信息不对称问题产生,进而影响价格崩盘;国有企业非效率投资对股价崩盘风险的影响大于非国有企业,但是制度环境的抑制作用对国有企业样本不明显。本文的研究结果为从宏观层面降低股价崩盘风险提供了经验证据,为维护我国股市稳定发展,推进国家治理体系建设提供了政策启示。     

货币政策、流动性不足与个股暴跌风险

本文以2004-2012年中国A股上市公司为研究样本,研究货币政策是否影响个股暴跌风险,以及基金和个股流动性不足对货币政策效果的影响。研究结果表明:(1)货币政策紧缩会显著增加个股的暴跌风险;(2)基金流动性不足和个股流动性不足会显著增加紧缩货币政策对股价暴跌风险的影响;(3)其他机构投资者能够缓解紧缩货币政策以及基金流动性不足对股价暴跌风险的影响。本文丰富了股价暴跌风险研究,同时对于货币政策制定及流动性管理有一定的现实意义。     

上市公司业绩预告偏差对股价崩盘风险的影响—基于内部控制的视角

利用我国A股2012-2018年上市公司数据,探讨上市公司业绩预告偏差与偏离方向如何影响股价崩盘风险,以及内部控制质量对两者的调节作用。研究发现:公司业绩预告偏差与股价崩盘风险显著正相关;与悲观偏差相比,业绩预告乐观偏差才会加剧股价崩盘风险,高质量的内部控制能够缓解业绩预告乐观偏差加剧的股价崩盘风险。进一步研究发现,当上市公司业绩预告需要强制披露、披露越及时及披露坏消息时,内部控制质量的调节作用更加显著。由此证明,高质量内部控制在缓解因业绩预告乐观偏差加剧的股价崩盘风险中发挥重要作用。     

员工外部薪酬差距与股价崩盘风险

本文基于2008年至2018年信息传输、软件和信息技术服务业上市公司的经验数据,研究发现非国有企业员工外部薪酬差距与股价崩盘风险显著正相关。进一步研究发现,员工外部薪酬差距与股价崩盘风险的显著关系只存在于业绩中等的企业。本文的结论有助于扩展关于股价崩盘风险影响因素的研究,为防范股价崩盘风险和制定合理的员工薪酬政策提供经验数据支持。     

企业过度投资与股价崩盘风险

实体经济的过热投资是否会导致股市出现“泡沫”进而引发股市的暴跌风险是当前学术界和实务界关注的一个焦点问题。本文以2004-2013年A股上市公司为样本,从微观层面考察企业过度投资对股价崩盘风险的影响,并从“代理理论”和“管理者过度自信”两种视角分析其背后的作用机理。研究结果表明:(1)企业过度投资显著加剧了股价未来的崩盘风险;(2)股东与经理人之间的代理冲突而非管理者过度自信是导致二者正相关的主要原因;(3)进一步的研究发现,企业过度投资对未来股价崩盘风险的影响具有长期性,且其对股价未来的暴涨不具有预测能力。本文的研究结论不仅丰富了股价崩盘风险、过度投资等相关领域的文献,对于如何抑制实体经济投资过热以降低股价崩盘风险、维护金融市场稳定也具有重要的参考价值。     

现金股利、控制权结构与股价崩溃风险

本文研究了上市公司在具有不同实际控股股东控制权结构下,现金股利与股价崩溃风险的关系。结果表明,过度支付现金股利会显著增加上市公司的股价崩溃风险;实际控制股东控制权与现金流权的分离程度会加剧现金股利与股价崩溃风险之间的正向关系。我们认为这一现象是现金股利中所蕴含的股东治理效应在资本市场上的体现。其现实意义在于,政策监管要着力于治“本”,通过提升公司治理水平以使股利分配真正立足于保护全体股东的利益。     

监管风险、事务所规模与审计质量

我国会计师事务所规模与审计质量之间是否存在正相关关系,现有研究一直存在争议。本文从注册会计师的执业环境出发,对此进行了重新审视。用上市公司实际控制人的控制权与现金流权之差衡量事务所面临的监管风险,研究发现,大事务所只对监管风险较高的客户提供高质量的审计服务。进一步的研究表明,事务所面临的监管环境改善后,大事务所才对所有客户提供高质量的审计服务,审计质量与事务所规模之间的正相关关系不再依赖监管风险而存在。因此,在法律环境相对薄弱的情况下,加强监管是促使会计师事务所提供高质量审计服务的有效机制。     

董事高管责任保险能否抑制股价崩盘风险——基于中国A股上市公司的经验数据

股价崩盘严重损害投资者利益并阻碍股票市场健康发展,因此,探寻抑制股价崩盘风险的手段成为当前公司治理与企业财务领域关注的热点问题。使用2009~2013年我国 A 股上市公司数据为样本,实证检验董事高管责任保险与公司股价崩盘风险之间的关系。研究发现：上市公司购买董事高管责任保险能有效监督与约束高管利己行为,进而降低股价崩盘风险。该结论有助于深入了解董事高管责任保险,同时也为监管部门遏制股价崩盘现象提供了新的思路。     

管理层能力与股价崩盘风险——基于盈余管理中介效应的检验

利用2007—2016年我国证券市场上市公司A股数据,研究管理层能力与股价崩盘风险之间的关系,并在此基础上探究不同盈余管理方式在两者关系中发挥的作用。结果表明：上市公司管理层能力越强,股价崩盘风险越小;真实盈余管理程度在管理层能力与股价崩盘风险关系中表现的中介效应更显著。     

Voluntary Adoption of the IFRS and Industry-Level Comparability: Evidence from Korean Unlisted Firms

This study examines the role of industry-level comparability with regard to voluntary adoption of the international financial reporting standards (IFRS) by unlisted firms in Korea. Mandatory adoption of the IFRS for listed firms in 2011 inhibits financial statement comparability between listed and unlisted firms. Our empirical findings reveal that unlisted firms in industries with higher ratios of listed firms tend to adopt the IFRS voluntarily. After this adoption, such unlisted firms seem to attract greater investment in the public debt market.     

股价暴跌、投资者认知与信息透明度

本文基于Merton(1987)不完全信息市场下的认知风险假说,研究了我国股票市场个股股价暴跌与投资者认知风险的关系。我们发现投资者认知风险越大,股价暴跌的风险越大,股价暴跌造成的损失也越大。进一步我们研究了影响认知风险的因素,发现在控制住经营风险和异质信念后,信息披露不透明是影响投资者认知风险的重要因素。稳健性检验的结果表明我们的发现并不受所使用的数据频率的影响。     

Early Adoption of IFRS as a Strategic Response to Transnational and Local Influences

In recent years, International Financial Reporting Standards (IFRS) have been adopted by nations throughout the world. Proponents and standard setters assert that IFRS will produce a number of benefits including improved transparency, international comparability, market efficiency, and cross-national investment flow. In this study, we examine factors that contributed to the early national-level adoption that occurred prior to broad global acceptance of IFRS. Using a conceptual framework of institutional theory and resource dependence, we propose that the interplay of transnational pressures and local factors influenced the level of adoption. We predict differential adoption as a strategic response at three levels of either require IFRS, permit IFRS, or do not allow IFRS, using a sample of 71 countries. As predicted, countries with greater resource dependency, as evidenced by weak governance structures and weak economies, were the early adopters who were more likely to require the use of IFRS. Further, resource dependence also trumps nationalistic pressures against transnational conformity. Our findings raise concerns that required adoption may not always be accompanied by an appropriately supportive infrastructure; thus, there are implications not only for adoption of IFRS, but also for the diffusion of other transnational regulation that influences global business environment.     

Effects of the Adoption of IFRS on the Credit Market: Evidence from Brazil

Based on a sample of approximately 6500 credit ratings and 137,000 loan contracts, this paper analyzes the effects of mandatory IFRS adoption on the Brazilian credit market. We find that the IFRS adoption effects were limited to firms displaying improved accounting information quality at the time of transition, lending support to the notion that economic benefits do not necessarily flow from the publication of financial reports in IFRS but, rather, depend on how earnestly firms adopt the recommended disclosure practices.     

Audit Effort and Stock Price Crash Risk

We examine how stock price crash risk is affected by audit effort, as measured by audit hours. Using a unique dataset of audit hours in China, we find that audit effort is negatively related to crash risk. The negative impact of audit effort on crash risk is more pronounced for listed firms that have higher inherent risks and weaker external monitoring of their information environment. Our findings are robust to various tests, including a two-stage regression analysis, controlling for listed firm-fixed effects and audit firm-fixed effects, and using alternative measures of crash risk. In addition to audit output measures, audit effort has an incremental influence on crash risk. The effects of audit effort on crash risk continue to hold after controlling for auditor industry expertise and auditor tenure.     

Choices in IFRS Adoption in Spain: Determinants and Consequences

New Spanish GAAP based on IFRS came into force for separate financial statements in 2008. Companies were allowed to choose between 1 January 2007 and 1 January 2008 as their transition date. The first option commits companies to presenting comparative statements while the second allows them to disclose only the adjustments in equity. We analyze the determinants of companies that decided to choose early transition and also the consequences of this choice on the main accounting figures and ratios. Our results show that the determinants of the early transition date are size and growth. As for the consequences, there is a significant change in the accounting figures and ratios and therefore comparability may be impaired.
