公司治理影响盈余管理的实证研究

尽管公司管理者有着各种各样的盈余管理动机,但是真正实施盈余管理行为会受到很多因素的影响,其中公司治理是最主要的影响因素。公司治理包括很多内容,本研究主要关注股权结构和董事会特征两方面与盈余管理之间的相关性。一般来讲,股权集中度与盈余管理呈正相关,董事会独立性与盈余管理呈负相关。本文在分析如何影响盈余管理的理论基础上,以2005至2009年我国上证180成分股为研究对象,提出研究假设并进行实证检验。结果显示,法人股比例、流通股比例与盈余管理呈现正相关关系,董事会特征则受制度影响,具有双重影响。文章最后,结合我国资本市场的实际提出相关建议。     

Forecasts in IPO Prospectuses: The Effect of Corporate Governance on Earnings Management

Prior research suggests that managers may use earnings management to meet voluntary earnings forecasts. We document the extent of earnings management undertaken within Canadian Initial Public Offerings (IPOs) and study the extent to which companies with better corporate governance systems are less likely to use earnings management to achieve their earnings forecasts. In addition, we test other factors that differentiate forecasting from non‐forecasting firms, and assess the impact of forecasting and corporate governance on future cash flow prediction. We find that firms with better corporate governance are less likely to include a voluntary earnings forecast in their IPO prospectus. In addition, we find that while IPO firms use accruals management to meet forecasts; the informativeness of the discretionary accruals depends on whether or not the firm would have missed its forecast without the use of discretionary accruals.     

公司治理水平、董事高管责任保险与盈余管理

董事高管责任保险在董事和高管遭受民事诉讼时具有“兜底”效应,降低了董事高管的执业风险.选取2002-2014年中国A股上市公司为样本,实证检验董事高管责任保险对公司盈余管理的影响,进一步分析在不同公司治理水平下,董事高管责任保险与公司盈余管理的关系是否存在差异.研究结果表明:董事高管责任保险的引入会加剧公司盈余管理行为;随着公司治理水平提高,董事高管责任保险与公司盈余管理的正相关关系减弱.

本文在分析公司治理机制的基础上,将影响公司治理的各个因素进行量化,通过构建上市公司估值模型,对公司治理影响估值进行实证分析.本文的结论是,公司治理对上市公司估值的影响很大;治理结构完善的公司,其估值水平相对较高,反之亦反之.     

公司管理者过度自信、过度投资行为与治理机制——来自中国上市公司的证据

本文从行为金融学视角出发,以2002~2009年中国A股上市公司为研究对象,研究管理者过度自信这一心理因素对公司过度投资行为的影响,并检验了公司内外部治理机制对它的抑制作用。研究表明,中国上市公司的管理者过度自信与公司过度投资行为之间存在显著正相关关系,而现有的公司治理机制并不能对这种非效率行为进行有效约束。本文的研究发现有助于我们更好理解中国上市公司的过度投资行为,也对如何完善中国上市公司治理机制有一定启示意义。     

临时CEO与盈余管理——基于中国上市公司的经验证据

我国大部分企业缺乏接班人计划,现任CEO突然离职导致企业不得不任命临时CEO代为行使职权。本文以我国资本市场非金融类上市公司聘任的临时CEO为研究对象,发现出于转正预期,临时CEO有较强的动机进行盈余管理,并且更多地表现为正向盈余管理行为。进一步考察CEO个体特征后发现,临时CEO是内部委任和在上市公司领取薪水的情况下更倾向于进行盈余管理。此外,有效的公司治理机制对临时CEO的盈余管理行为存在抑制作用。研究结论对于我国企业制定接班人计划具有重要的指导意义。     

我国上市公司盈余管理对股价影响的实证分析

盈余管理在西方被称为“市场参与者的游戏”,近年来日益受到我国会计学界的关注。证券市场的迅速发展要求上市公司提供高质量的会计信息,由于盈余管理与会计信息质量关系密切,使得对上市公司盈余管理问题的研究成为投资者、债权人、政府主管部门以及会计准则制定机构关注的重点。另一方面,证券市场经验数据证明,股价的波动也同盈余管理密切相关,而利益相关者很可能利用盈余管理手段来影响股价从而获取利益。因此,加强我国上市公司盈余管理和股价相关性的研究,对提高上市公司会计信息质量和改善证券市场资源优化配置功能有着重要意义。本文运用实证分析方法,选取了竞争性强的家电行业和竞争性弱的石油行业的上市公司,从盈余管理度量着手,研究竞争性不同行业的上市公司盈余管理对股价的影响大小,并对投资者的行为提出相关建议。     

债务重组对上市公司盈余管理的影响——基于沪市A股上市公司的经验证据

我国财政部在1998年、2001年和2006年先后颁布和修订了债务重组准则,不同准则下债务重组损益的确认与计量有所不同。在这三个阶段,上市公司是否利用债务重组进行盈余管理．盈余管理程度和动机是否有所不同？针对这些问题,文章选取1999年、2006年和2007—2011年沪市A股的债务重组上市公司为样本,采用描述统计和多元回归方法研究不同债务重组准则下债务重组对盈余管理的影响。研究表明：将债务重组损益计入营业外收支的公司其盈余管理程度要高于将债务重组损益计入资本公积的公司;ST公司通过债务重组收益来粉饰报表达到扭亏为盈的目的。     

Corporate Ownership Structure and the Informativeness of Earnings

This study extends prior studies by examining how managerial ownership and external unrelated blockholdings affect the informativeness of earnings. The results are in contrast to prior studies. A non–linear relation exists between managerial ownership and earnings informativeness. Earnings informativeness increases with managerial ownership at low levels but not at higher levels of managerial ownership where the entrenchment effect sets in. Consistent with the role of large shareholder monitoring, the evidence shows a strong positive relationship between external unrelated blockholdings and earnings informativeness. These results are supported when income–increasing and absolute discretionary accruals are used to measure the extent of earnings management     

Corporate Governance Structure and Performance of Malaysian Listed Companies

Abstract:  This study investigates the relationship between the corporate governance structure and performance of 347 companies listed on the Kuala Lumpur Stock Exchange (KLSE) between 1996 and 2000. We found board size and top five substantial shareholdings to be significantly associated with both market and accounting performance measures. In addition, we found a significant relationship between multiple directorships and market performance while role duality and managerial shareholdings are significantly associated with accounting performance. The result is robust with respect to controls for gearing, company size, industry membership and growth opportunities.

The Emergence of Corporate Governance from Wall St. to Main St.: Outside Directors, Board Diversity, Earnings Management, and Managerial Incentives to Bear Risk

Recent corporate events have brought a heightened public awareness to corporate governance issues. Much work has been accomplished to date, but it is clear that much more remains to be done. This paper provides a review of empirical research in four relevant areas of corporate governance. Specifically, the paper provides an overview of (a) the role that outside directors play in monitoring managers, (b) the emerging literature on the impact of board diversity, (c) the existence of and incentives for corporate executives to manage firm earnings, and (d) managerial incentives to bear risk.     

公司所得税对资本结构的影响——基于中国上市公司的实证分析

国外大量的经验研究表明,税收是影响公司资本结构的重要因素。而我国具有自身特有的制度与经济背景,通过对我国上市公司财务数据进行检验,可以为我国税收是否影响公司资本结构,以及影响程度的大小提供实证方面的证据,并为进一步改善税收经济调节作用提供思路。     

股权结构与上市公司应计和真实盈余管理行为

过高的股权集中度会导致显著更高的应计盈余操控行为,而对真实盈余管理行为的影响总体上不显著;无论对于应计盈余操控还是真实盈余操控,机构持股均具有较好的抑制作用;国有控股会导致显著更高的应计盈余操控,但在真实盈余操控方面,更多地体现在异常酌量费用方面;国有控股上市公司管理层持股越高,其应计盈余管理行为越显著,而在真实盈余管...     

The Influence of Takeover Protection on Earnings Management

Abstract:  We examine the relationship between takeover protection and earnings management. Existing theories suggest two contradictory effects of takeover protection on opportunistic earnings management: entrenchment theory suggests an exacerbating effect, whereas both alignment theory and quiet life theory posit a mitigating effect. We find that takeover protection is associated with lower levels of abnormal working capital accruals, lower levels of performance-adjusted abnormal accruals and timelier recognition of losses. Further tests show that takeover protection is associated with lower firm value, which contradicts alignment theory but supports quiet life theory. The results suggest that takeover protection allows managers to enjoy the quiet life and thus mitigates earnings management.     

Earnings quality and short selling: Evidence from real earnings management in the United States

Prior research provides evidence consistent with managers using real earnings management (REM) to increase earnings. This study examines whether short sellers exploit the overvaluation of firms employing REM. I find that firms with more REM have higher subsequent short interest. The positive relation between REM and short interest is more pronounced in settings where the costs associated with accrual‐based earnings management are high, such as when a firm has low accounting flexibility or faces greater scrutiny from a high quality auditor. I also find some evidence that short sellers respond to REM more than to other fundamental signals of firm overvaluation. My inferences are robust to the use of propensity score matching. Collectively, my evidence suggests that short sellers not only trade on REM information, but they also trade as if they understand the substitutive nature of alternative earnings management methods. This study provides additional insight into the important role that short sellers play in monitoring managerial operating decisions and overall earnings quality.

The Impact of Corporate Governance Quality on Earnings Management: Evidence from European Companies Cross‐listed in the US

The study reported herein examines the impact of two central corporate governance mechanisms (internal audit function quality and board of directors’ quality) on the incidence of earnings management. Unlike most prior studies in the area, focused mainly on US firms, this study looks at European firms that are cross‐listed in the US and covers a long time span – before and after major changes were implemented in corporate governance policies (Sarbanes‐Oxley Act in the US and the 8th Company Law Directive in the European Union). Using novel and comprehensive measurement approaches for internal audit function quality and board of directors’ quality, we find that both mechanisms have a negative direct effect on the incidence of earnings management, while their interactive effect is positive. A longitudinal analysis of both mechanisms also reveals that internal audit function quality and the quality of boards of directors have increased significantly since the policy changes.     

Corporate Governance and Earnings Management: The Implications of Corporate Governance Best-Practice Principles for Taiwanese Listed Companies

This study investigates whether corporate governance characteristics, mandated by the Corporate Governance Best-Practice Principles (CGBPP) for companies listed in Taiwan, are associated with earnings management. In particular, we examine whether the independence, financial expertise, and voluntary formation of independent directorships (supervisorships) are associated with the absolute value of discretionary accruals. Our findings suggest that the independence of supervisors, the financial expertise of independent directors, and the voluntary formation of independent directorships (supervisorships) are associated with a lower likelihood of earnings management. These findings are stronger after the CGBPP was enacted, suggesting that the implementation of CGBPP has lowered the likelihood of earnings management.     

中国上市银行公司治理水平的比较评价

本文构建了中国上市银行公司治理评价系统,该系统侧重于公司内部治理机制评价。作者依据所构建的评价系统计算出了我国12家上市银行的公司治理评价指数,并进行了比较分析。结果表明,自1999年以来,我国上市银行治理水平呈快速上升趋势,但各银行间治理水平差异较大。从整体上而言,股份制商业银行的治理状况较好,其中招商银行的治理水平居所有样本银行的首位;工、中、建三大商业银行的治理状况相对一般,但它们上市后公司治理水平的不断提升也表明其改革是卓有成效的;已上市的城市商业银行的治理状况则要好于三大商业银行,这对城市商业银行未来的发展具有一定的指导意义。
