公司治理、机构投资者与盈余管理

本文选取沪深两市2003至2005年(非金融类)上市公司的数据,采用最小二乘法和二阶段回归方法,对公司治理、机构投资者与盈余管理三者的关系进行了实证研究。研究发现:机构投资者在一定程度上参与了上市公司的治理,其持股比例与公司治理水平呈正相关关系,说明机构投资者的持股比例越高越有助于提高公司治理水平;公司治理水平与盈余管理程度呈负相关关系;机构投资者的持股比例与盈余管理程度呈负相关关系,说明机构投资者能有效地抑制管理层的盈余管理行为。     

美国机构投资者在公司治理中的作用

在现代公司中，股东与管理之间存在着委托代理关系，因此股东需要一定的控制机制对管理进行监督和约束。从20世纪80年代末开始，以养老基金为代表的机构投资开始活跃地出现在美国的公司治理中。     

机构投资者参与公司治理行为指引制度研究

机构投资者参与公司治理是发挥中长期资金“压舱石”作用的重要途径,对于提升上市公司质量具有积极意义。研究发现,当前我国机构投资者在参与公司治理方面已取得一定实效,但仍存在总体积极性不高、制度不规范、披露不充分、手段有限、质量较低等问题,激励及引导规则的不足是导致实践困境的重要原因之一。有必要参考境外做法,引进具有软法性质的行为指引制度,构建具有约束力的促进型法制。相应规则的设计应以促进机构投资者有效行使股东权利为核心,着重加强对机构投资者的激励与引导,培育机构投资者自愿、自主和自觉参与公司治理的能力,推动机构投资者积极参与公司治理。     

Default Risk Estimation,Bank Credit Risk,and Corporate Governance

This study explores the relationship between credit risks of banks and the corporate governance structures of these banks from the perspective of creditors. The cumulative default probabilities are estimated for a sample of US commercial and savings banks to measure their risk taking behavior. The results show that one year and five year cumulative default probabilities are time‐varying, with a significant jump observed in the year prior to the financial crisis of 2008–09. Generally speaking, corporate governance structures have a greater impact on US commercial banks than on savings institutions. We provide evidence that, after controlling for firm specific characteristics, commercial banks with larger boards and older CFOs are associated with significantly lower credit risk levels. Lower ownership by institutional investors and more independent boards also have lower credit risk levels, although these effects are somewhat less significant. For all the banks in our sample, large board size, older CFO, and less busy directors are associated with lower credit risk levels. When we restrict the sample to consider the joint effects of the governance variables, the results on board size and busy directors are maintained.     

Corporate Governance, Idiosyncratic Risk, and Information Flow

We study the relationship of corporate governance policy and idiosyncratic risk. Firms with fewer antitakeover provisions display higher levels of idiosyncratic risk, trading activity, private information flow, and information about future earnings in stock prices. Trading interest by institutions, especially those active in merger arbitrage, strengthens the relationship of governance to idiosyncratic risk. Our results indicate that openness to the market for corporate control leads to more informative stock prices by encouraging collection of and trading on private information. Consistent with an information‐flow interpretation, the component of volatility unrelated to governance is associated with the efficiency of corporate investment.     

Behind the Scenes: The Corporate Governance Preferences of Institutional Investors

We survey institutional investors to better understand their role in the corporate governance of firms. Consistent with a number of theories, we document widespread behind‐the‐scenes intervention as well as governance‐motivated exit. These governance mechanisms are viewed as complementary devices, with intervention typically occurring prior to a potential exit. We further find that long‐term investors and investors that are less concerned about stock liquidity intervene more intensively. Finally, we find that most investors use proxy advisors and believe that the information provided by such advisors improves their own voting decisions.     

公司治理与财务治理

我国上市公司治理结构存在着先天性的制度缺陷, 表现在委托代理关系的严重失衡。在完善公司治理的过程中, 应逐步理顺财务报表审计关系和独立董事制度引入中的代理关系, 强化财务治理, 以促使上市公司持续健康的向前发展。     

A Matter of Record: Document Management as Part of Good Corporate Governance, Risk Management and Decision-Making

Good governance, risk management and decision-making are facilitated by a proactive approach to document management which includes keeping necessary records but goes beyond that in order to achieve efficient and effective organisational performance. This paper's focus is on organisational knowledge, which is increasingly facilitated by information technology, and communications to capture effectively the intelligence (broadly defined) and understanding of people within the organisation. Documentation of our knowledge assets is a major exercise in risk management and its associated control environment and essential for individual and collective accountability for performance.     

战略投资者对国有商业银行公司治理的影响

我国国有银行公司治理的关键性缺陷主要是出资人缺位问题、人事制度及扭曲的激励约束制度问题和风险管理制度缺失问题,战略投资者加入之后对这三方面的缺陷都有改进作用,有利于国有银行公司治理水平的提高,但是囿于我国金融基础性制度的缺失和地方政府干预金融的政治体制缺陷,战略投资者并不能从根本上改变我国国有银行的公司治理状况.……     

税务筹划、公司治理与股价暴跌风险

以我国2011~2013年沪市A股数据为样本,研究税务筹划程度与股价暴跌风险之间的关系,结果显示,随着税务筹划程度的提高,个股股价暴跌的风险显著增加。进一步发现,税务筹划对股价暴跌风险的影响在治理水平较低的公司中更加显著。这一结论有助于分析我国个股暴跌频繁的深层原因,同时提示企业所有者既要权衡税务筹划的边际收益与边际成本,还要提高公司治理水平,防止管理层产生机会主义行为,以有效预防股价暴跌的风险。

Private Equity,Corporate Governance,and the Reinvention of the Market for Corporate Control

In the early 1980s, during the first U.S. wave of debt‐financed hostile takeovers and leveraged buyouts, finance professors Michael Jensen and Richard Ruback introduced the concept of the “market for corporate control” and defined it as “the market in which alternative management teams compete for the right to manage corporate resources.” Since then, the dramatic expansion of the private equity market, and the resulting competition between corporate (or “strategic”) and “financial” buyers for deals, have both reinforced and revealed the limitations of this old definition. This article explains how, over the past 25 years, the private equity market has helped reinvent the market for corporate control, particularly in the U.S. What's more, the author argues that the effects of private equity on the behavior of companies both public and private have been important enough to warrant a new definition of the market for corporate control—one that, as presented in this article, emphasizes corporate governance and the benefits of the competition for deals between private equity firms and public acquirers. Along with their more effective governance systems, top private equity firms have developed a distinctive approach to reorganizing companies for efficiency and value. The author's research on private equity, comprising over 20 years of interviews and case studies as well as large‐sample analysis, has led her to identify four principles of reorganization that help explain the success of these buyout firms. Besides providing a source of competitive advantage to private equity firms, the management practices that derive from these four principles are now being adopted by many public companies. And, in the author's words, “private equity's most important and lasting contribution to the global economy may well be its effect on the world's public corporations—those companies that will continue to carry out the lion's share of the world's growth opportunities.”     

国内商业银行风险治理问题初探

正近年来,我国银行业快速成长,传统的风险管理概念无法涵盖商业银行管理风险的全部理念与实践,风险治理(riskgovernance)受到越来越多的关注。商业银行风险治理是董事会、监事会、高级管理层、股东、监管部门等不同的利益相关者在银行风险识别、评估、管理和沟通等方面做出决策的原则、策略和机制,重点是指董事会和高级管理层在风险战略的制定与执行方面所形成的监督与制衡机制。     

完善公司治理与管理会计创新

本文认为 ,会计信息系统在公司治理中的作用还有待进一步全面认识。财务会计信息由于受多种因素的限制 ,不能完全满足公司治理的要求 ;而管理会计也需要重新构造其目标和方法体系 ,才能有助于公司治理。管理会计与财务会计都是为公司的内外部服务 ,两者的差异从根本上说源自信息披露是否具有强制性。为推进管理会计的改革和发展 ,应重视会计系统的环境因素、管理制度创新与规范的结合和会计信息的内在性质。     

公司会计治理与公司治理:同构、嵌入还是交叉?

公司会计治理通常被看作是公司治理的一部分,而且将公司会计治理看作是嵌入公司治理中或与公司治理同构。因此,以公司治理为导向的会计治理强调弥合公司治理中委托代理关系链务的缺陷及其对审计独立性的影响。本文从会计信息产权演变的角度将公司会计治理从公司治理中“解析”出来,认为公司治理与公司会计治理同源于委托代理难题,但治理的基础和目标不同,公司治理的监督机制与会计治理对监督机制的内在需求是不同的,因此,公司会计治理结构与公司治理结构应该是交叉的或大部分同构,同属于现代企业组织制度的范畴。本文主张应按照公司会计治理的逻辑结构及其与公司治理的关联性对其进行研究和建构。     

The Effect of Corporate Governance on the Use of Enterprise Risk Management: Evidence From Canada

This article examines the use of enterprise risk management (ERM) by companies in Canada, the characteristics that are associated with the use of ERM, what obstacles companies face in implementing ERM, and what role, if any, corporate governance guidelines have played in the decision to adopt ERM. We obtained our data from the responses to a mail survey sent to Canadian Risk and Insurance Management Society members as well as telephone interviews with 19 of the respondents. The results indicate that 31 percent of the sample had adopted ERM and that reasons for adopting ERM include the influence of the risk manager (61 percent), encouragement from the board of directors (51 percent), and compliance with Toronto Stock Exchange (TSE) guidelines (37 percent). The major deterrents to ERM were an organizational structure that discourages ERM and an overall resistance to change. Although only about one‐third of companies indicated that they had adopted an ERM approach, evidence was clear that a larger portion of the sample was moving in that direction, as indicated by what changes they had observed in their companies in the past three years. These include the development of company‐wide guidelines for risk management (45 percent), an increased awareness of nonoperational risks by operational risk management personnel and an increased awareness of operational risks by nonoperational risk management personnel (49 percent), more coordination with different areas responsible for risk management (64 percent), and more involvement and interaction in the decision making of other departments. Contrary to what we expected, there was not a significant difference between firms that are listed on the TSE versus those that are not in terms of the propensity to use ERM. However, the fact that 37 percent of firms indicated that the TSE guidelines were influential in their decision to adopt ERM provides some evidence that the guidelines are influencing companies’ risk management strategies.     

Corporate Finance and Corporate Governance

A combined treatment of corporate finance and corporate governance is herein proposed. Debt and equity are treated not mainly as alternative financial instruments, but rather as alternative governance structures. Debt governance works mainly out of rules, while equity governance allows much greater discretion. A project-financing approach is adopted. I argue that whether a project should be financed by debt or by equity depends principally on the characteristics of the assets. Transaction-cost reasoning supports the use of debt (rules) to finance redeployable assets, while non-redeployable assets are financed by equity (discretion). Experiences with leasing and leveraged buyouts are used to illustrate the argument. The article also compares and contrasts the transaction-cost approach with the agency approach to the study of economic organization.
