机构持股与中小投资者保护

信息不对称是导致中小投资者在资本市场遭受利益损失的重要原因,本文以会计盈余质量作为衡量中小投资者保护水平的指标,以2003-2005年沪、深两市A股为样本,实证检验了中国机构持股对中小投资者保护的影响.结果发现,机构持股降低了会计盈余质量,没有发挥保护中小投资者的利益的作用.上述研究发现,对理解机构持股的经济后果具有重要意义,有助于更加深入地理解机构持股影响中小投资者利益保护的制度条件,也为投资者保护研究提供了一个有益的视角.     

信息透明度与散户的交易选择——基于深圳交易所上市公司的实证研究

股市的风险往往归因于散户的交易,大力发展机构投资者成为提高市场效率的不可挑战的信条。透过微结构数据的分析,本文发现散户交易存在过度自信特征,可能过度高估私有信息精确度,导致错误定价信息。分离了过度自信的因素后,本文发现信息透明度为散户交易的重要依据。更为重要的是本文发现,相对于散户而言,信息透明度对机构投资者交易的影响较低,说明了信息透明度对处于信息劣势的投资者具有更重要的现实意义。     

机构投资者股权对银行公司治理与绩效的影响

在机构投资者对银行进行投资时,不同类型的机构投资者具有不同的表现.其中,QFII、证券公司、社保和保险基金都能影响银行的公司治理,促进其综合业绩的提高;证券投资基金和企业不能对这两个方面产生显著影响.在选择银行股时,证券投资基金注重银行过去综合业绩的表现,企业、社保基金和保险基金注重银行过去市场价值的增长,QFII和证券公司同时考虑了这两个方面.实行银行股权全流通,放松时机构投资者的管制,改革证券交易方面的税收制度,培养机构投资者的投资理念,有利于发挥机构投资者对银行公司治理的积极作用.     

Investor Sentiment and Corporate Disclosure

This paper investigates how firms react strategically to investor sentiment via their disclosure policies in an attempt to influence the sentiment‐induced biases in expectations. Proxying for sentiment using the Michigan Consumer Confidence Index, we show that during low‐sentiment periods, managers increase forecasts to “walk up” current estimates of future earnings over long horizons. In contrast, during periods of high sentiment, managers reduce their long‐horizon forecasting activity. Further, while there is an association between sentiment and the biases in analysts' estimates of future earnings, management disclosures vary with sentiment even after controlling for analyst pessimism, indicating that managers attempt to communicate with investors at large, and not just analysts. Our study provides evidence that firms' long‐horizon disclosure choices reflect managers' desire to maintain optimistic earnings valuations.     

Ownership, Investor Protection and Earnings Expectations

Abstract:  This study examines the interactive influence of corporate ownership, corporate governance and investor protection on the incorporation of current value shocks in the accounting earnings of European companies. This influence is investigated not only by means of the association between current news and current earnings but also with respect to the association of the same news with expected future earnings, and its persistence. Consistent with the contractual explanation of accounting conservatism, it is shown that the accounting behaviour examined is a function of the demand created by shareholders, and that the institutional arrangements in force are of lesser significance in the presence of widely held ownership. On the other hand, greater separation between supervision and management and stronger investor protection are seen to be influential under close ownership, as these are shown to curb aggressive accounting in the form of a persistently lower recognition of bad news in earnings. Evidence is also provided that stricter corporate governance practices in Europe can substitute for weaknesses in investor protection provisions in law.     

公司治理机制对公司透明度的影响——来自中国上市公司的经验数据

越来越多的国家把公司透明度作为衡量公司治理效率的标志 ,并为提高企业透明度做出了种种努力。中国同样面临提高公司透明度的问题 ,然而截至目前 ,国内并没有关于企业透明度与公司治理机制之间关系的实证研究。本文以我国上市公司作为研究对象 ,以自愿性信息披露水平作为公司透明度的替代变量 ,分析了公司治理机制对公司透明度的影响。     

Managerial Self-Interest, Pension Financial Slack and Corporate Pension Funding

This paper examines the impact of managerial self-interest on corporate pension funding decisions. It is postulated that managers with no ownership stake in the firm will have incentives to maintain financial slack in the form of excess pension funding. Pension funding slack may be viewed as a managerial perquisite that decreases the probability of necessary future debt financing. Such a strategy may increase the value of undiversified human capital to the detriment of maximizing shareholder wealth. As managerial ownership increases, the incentives to consume such a perquisite will decrease since the interests of managers and shareholders become more aligned. The results presented in this study strongly support this proposition.     

机构投资者持股、现金股利政策与公司价值——来自2005-2010年中国上市公司的经验证据

现金股利政策,决定了机构投资者的收益模式选择——长期持有的价值投资抑或短期频繁买卖的投机炒作,进而影响机构投资者能否帮助上市公司提升公司价值。论文基于2005-2010年中国A股上市公司7159个年度观察数据,实证研究发现,当且仅当上市公司(连续)发放(较高)现金股利时,机构投资者持股才能显著提升公司的市场价值,而且此时机构投资者持股比例还必须达到较高的水平。该结论在控制内生性、计量模型选择、变量度量等问题后仍然稳健成立。     

What Determines Corporate Transparency?

We investigate corporate transparency, defined as the availability of firm‐specific information to those outside publicly traded firms. We conceptualize corporate transparency within a country as output from a multifaceted system whose components collectively produce, gather, validate, and disseminate information. We factor analyze a range of measures capturing countries' firm‐specific information environments, isolating two distinct factors. The first factor, interpreted as financial transparency, captures the intensity and timeliness of financial disclosures, and their interpretation and dissemination by analysts and the media. The second factor, interpreted as governance transparency, captures the intensity of governance disclosures used by outside investors to hold officers and directors accountable. We investigate whether these factors vary with countries' legal/judicial regimes and political economies. Our main multivariate result is that the governance transparency factor is primarily related to a country's legal/judicial regime, whereas the financial transparency factor is primarily related to political economy.     

代理问题、投资者保护与公司价值——来自我国上市公司的经验证据

本文以2002～2004年2238家上市公司为样本，按照最终控制人性质，将样本公司分为国有和民营金字塔控制两种主要类别，研究了代理问题在哪些公司较为严重，法律对于投资者保护是否能起到有效的治理作用。研究结果表明，国有和民营上市公司价值并无显著差异；随着政府层级的提升，国有控制公司价值提高；民营金字塔控制公司最终控制人所有权与控制权的分离对公司价值有负向作用；法治水平高的地区，其所属公司价值较高；海外上市提高了民营公司价值，但对国有公司的作用不显著；证券监管机构发挥的作用尚存不足。     

Managerial Ownership and Corporate Hedging

Abstract:  Using information on 443 UK non-financial companies, this work provides evidence supporting the hypothesis that managerial risk aversion is an incentive to deviate from the optimal hedging position. Conflicts of interest between shareholders and managers are at the centre of the decision about the firm's risk profile but are not relevant as determinants of the decision to hedge. This is rather associated with factors enhancing the firm's expected value (underinvestment, scale economies, tax savings).     

Corporate Bond Market Transaction Costs and Transparency

Using a complete record of U.S. over‐the‐counter (OTC) secondary trades in corporate bonds, we estimate average transaction costs as a function of trade size for each bond that traded more than nine times between January 2003 and January 2005. We find that transaction costs decrease significantly with trade size. Highly rated bonds, recently issued bonds, and bonds close to maturity have lower transaction costs than do other bonds. Costs are lower for bonds with transparent trade prices, and they drop when the TRACE system starts to publicly disseminate their prices. The results suggest that public traders benefit significantly from price transparency.     

内部控制、治理环境与投资者保护

本文研究了内部控制质量对投资者保护的影响,以及不同治理环境对内部控制治理功能的影响。研究发现:内部控制质量的提高,或更为充分的内控信息披露有助于抑制大股东资金占用,有助于抑制经理人与股东之间的代理成本;治理环境越差的地区,内部控制治理效应越高。这说明,对于投资者保护较弱的地区,内部控制可能成为补偿弱投资者保护负面影响的一种替代机制。本文研究意味着,近年来推出的内部控制相关制度起到了积极的效果;此外,完善上市公司内部控制,对于治理环境较差、投资者利益得不到有效保障的地区显得尤为重要。     

Investor Behavior and the Benefits of Direct Stock Ownership

Using an experiment to rule out reverse causality, we examine whether a small investment in a company's stock leads investors to purchase more of the company's products and adopt other views and preferences that benefit the company. We preregister our research methods, hypotheses, and supplemental analyses via the Journal of Accounting Research’s registration‐based editorial process. We find little evidence consistent with these hypotheses for the average investor in our sample using our planned univariate hypothesis tests, and planned Bayesian parameter estimation shows substantial downward belief revision for more optimistic ex ante expectations of the treatment effects. In planned supplemental analyses, however, we do find that the effects of ownership on product purchase behavior and on regulatory preferences are intuitively stronger for certain subgroups of investors—namely, for investors who are most likely to purchase the types of products offered by the company and for investors who are most likely to vote on political matters. The results contribute to our understanding of the benefits of direct stock ownership and are informative to public company managers and directors.     

Complex Ownership Structures and Corporate Valuations

The bulk of corporate governance theory examines the agencyproblems that arise from two extreme ownership structures: 100%small shareholders or one large, controlling owner combinedwith small shareholders. In this paper, we question the empiricalvalidity of this dichotomy. In fact, one-third of publicly listedfirms in Europe have multiple large owners, and the market valueof firms with multiple blockholders differs from firms witha single large owner and from widely held firms. Moreover, therelationship between corporate valuations and the distributionof cash-flow rights across multiple large owners is consistentwith the predictions of recent theoretical models.     

机构投资者的发展对资本市场的影响——以美国为例的分析

机构投资者的发展无论是从哪一个方面来说，对证券市场都有着积极的正面的影响。尽管我国在发展机构投资者过程中暴露出各种各样的问题，但这主要是由于没有经验和监管手段不足等原因造成的，不能因此而质疑大力发展机构投资者的政策思路。……     

大股东控制、投资者保护与公司治理

本文旨在提供一个对大股东控制下的公司治理实践差异的理论解释。在缺乏有效保护中小股东利益的外部法律,并且存在政府对证券市场发展托市行为的基础上,较低的公司治理绩效和证券市场的表面繁荣可以共存。公司治理模式选择的方向不在于公司股权的分散化,而在于政府改变对证券市场发展的特殊偏好。     

投资者情绪、经理激励契约与企业投资

本文基于中国上市公司经理激励契约安排的制度背景,把经理激励契约纳入投资者非理性分析框架,就投资者情绪与经理激励契约如何相互作用影响企业投资进行了理论分析,并进行了实证检验。结果发现,高管持股会诱发高管利用投机的股市进行过度投资,而与股价弱相关的货币薪酬没有这种作用,而且经理薪酬的这种作用因企业实际控制人性质不同而有所差异。本研究表明高管持股在企业投资决策中具有负面的公司治理效应。     

国有产权、公司特征与困境公司绩效

尽管众多研究表明国有产权在公司正常经营期间会降低绩效,但一旦陷入财务困境,源于国有产权的预算软约束却可以降低财务困境成本,从而有利于国有公司。本文以1999—2005年期间发生财务困境的上市公司为研究对象,发现在财务困境期间国有产权对公司绩效具有积极影响,并且当公司规模较小或者财务杠杆较高时,这种积极作用更为明显。     

Institutional Ownership and Distribution of Equity Returns

Although there is considerable evidence of the importance of skewness and kurtosis in equity returns, much less attention has been paid to their determinants. Recent theoretical and empirical advances in the literature suggest that the information structure and other market characteristics affect the nature of return distributions. One such characteristic is the degree of institutional ownership in the stock. This study hypothesizes and documents a significant inverse relationship between the degree of institutional ownership and the standard deviation, skewness, and kurtosis of equity returns.
