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.     

机构投资者持股、盈余管理与市场反应

由于会计信息的专业性,个人投资者往往难以从会计数据中识别盈余管理;而作为投资专家的机构投资者能否识别盈余管理,并将其融入到市场价格机制中则成为人们关注的焦点。通过检验机构投资者持股对公司股票累计超额报酬率和盈余管理之间关系的影响,研究发现:机构投资者持股较高的股票的超额报酬率与正向操纵性应计利润显著负相关,说明机构投资者股东能从会计信息中识别公司的盈余管理行为,并将其反映到市场价格机制中去。     

机构投资者、信息披露与盈余管理

本文以反映公司治理效率的信息披露与盈余管理作为关注要点,深入研究了机构投资者持股的治理效果问题.本文研究表明,机构投资者持股公司的盈余管理程度显著低于无机构投资者持股公司,并且盈余管理程度随着机构投资者持股的增加而显著降低.本文还检验了机构投资者持股能否有效提高公司信息披露的质量,发现机构投资者持股公司的信息披露质量显著高于无机构投资者持股公司,而且信息披露质量随着机构投资者持股的增加而提高.本文还发现,机构投资者持股公司信息披露对于盈余管理的监控作用更为显著,并且随着机构投资者持股的增加促进作用更为明显.以上发现意味着目前我国机构投资者已经参与到公司治理中,并在一定程度上发挥了积极的治理作用.     

异质机构投资者持股对上市公司盈余持续性的影响研究

通过对我国A股市场数据的实证检验和分析,检验不同类型的机构投资者持股行为对公司盈余持续性的影响.研究发现,我国A股市场上市公司存在盈余持续性,并且现金流量的持续性要高于会计应计的持续性;机构投资者持股比例越高,公司盈余持续性越强;独立机构投资者持股比例大的公司盈余持续性较强,非独立机构投资者持股比例对上市公司盈余持续性无显著影响;机构投资者持股集中度越高的公司盈余持续性越强.     

机构投资者持股与股价同步性分析

本文利用中国证券市场所有A股上市公司2005～2007年的面板数据,对股价同步性和代表机构投资者持股的三个变量——机构投资者持股比例、机构投资者持股变化和持股机构投资者数量进行回归统计,检验了机构投资者持股对股价同步性的影响。研究表明,代表机构投资者持股的三个变量都与股票股价同步性显著负相关,其中机构投资者持股变化是影响股价同步性的决定性因素,其他两个变量都是通过该变量发生作用的。这一结果说明机构投资者利用公司特质信息进行的基于信息的交易提高了股价中的信息含量,降低了股价同步性。     

场外市场会计盈余的信息含量

以万德数据库提供的新三板企业为样本,检验场外主体市场的会计盈余信息含量。混合样本检验显示,盈余信息披露对投资者超额收益有显著影响。分期检验中,2009年披露的盈余信息还不具备有效的信息含量;2010年披露的盈余信息具有信息含量,可能预示着场外市场的完善和成熟。此外,样本检验结果没有找到场外市场具有半强势有效的证据,但可以推断该市场处于弱势有效状态。     

机构投资者与真实盈余管理

机构投资者是对上市公司进行外部监管的重要力量,对公司治理意义重大。传统意义上的盈余管理是对应计项目进行盈余操控。但目前市场机制和政策越来越完善,应计盈余管理的空间越来越狭窄,企业管理者开始寻求更加隐蔽的盈余管理方法,也就是真实盈余管理。那么外部的机构投资者对真实盈余管理会产生何种效果?为了对以上问题进行研究,本文选取2012~2015年中国上市公司为研究对象和样本。本文的研究表明:机构投资者对上市公司的真实盈余管理行为具有一定的制约作用。     

机构投资者持股特征的实证分析

本文通过对2004年以前在中国证券市场上A股公司机构投资者持股的特征实证分析,从中得出机构投资在选择股票时对上市公司的流动性、盈利性和增长性并不十分看重的结论,也就是说机构投资者持有的上市公司在流动性、盈利性和增长性方面与那些机构投资者持有比例低的公司相比并没有显著差异。但是机构投资者会倾向于选择股权结构良好的上市公司,这意味着机构投资者可能会对公司治理起到一定的积极作用。     

机构投资者与盈余管理关系研究综述

近年来,随着机构投资者逐渐成为证券市场的重要力量,并且作用越来越明显,越来越多的学者开始对机构投资者进行了相应的研究,这方面的文献也在增加.这其中,对机构投资者与盈余管理关系的研究也成为一个热点.本文就通过对相关机构投资者与盈余管理的关系国内文献进行了一定的梳理,进而进一步分析两者之间的关系.     

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。     

Institutional Ownership,Diversification, and Riskiness of Bank Holding Companies

We examine the relationship among the level and stability of institutional ownership, diversification, and riskiness of publicly traded bank holding companies. We find that large and stable institutional ownership is associated with a higher (lower) level of geographic, revenue, and nontraditional banking (asset) diversification and lower risk, suggesting that institutional investors are prudent and favor risk‐reducing diversification strategies. The association between institutional ownership level and diversification is more pronounced under deregulation and during the crisis, suggesting a substitution effect between regulation and market discipline, and a greater level of monitoring and/or advising by institutional investors during the crisis, respectively.     

机构投资者与上市公司会计信息相关性分析

本文从机构投资者与会计信息相关性之间的联系来说明机构持股在公司治理中的作用。本研究以1999～2002年深市A股为样本，研究发现，在样本时间区闸内会计信息相关性与机构持股比例相关性不明显；从年度样本研究发现，随着机构持股比例增加，会计信息相关性增强，说明近年求机构投资者已参与公司治理，并发挥一定怍用。     

Institutional Ownership Type and Earnings Quality: Evidence from Iran

Institutional ownership is an important factor in corporate governance. Institutional investors play important roles in firms because of their substantial shareholdings and their capability to monitor managers. However, the question is whether they are capable of monitoring the managers. The literature has provided different evidence for the monitoring role of institutional investors. This study attempts to provide insights into the monitoring roles of institutional investors by examining the relationship between institutional ownership and earnings quality on the Tehran Stock Exchange. Institutional investors are classified into two groups, namely active institutional investors and passive institutional investors, based on their monitoring power in Iran. A multidimensional method is used to measure the various aspects of earnings quality, such as earnings response coefficient, predictive value of earnings, discretionary accruals, conservatism, and real earnings management. The results show that institutional ownership has a positive effect on earnings quality. Similar to total institutional ownership, active institutional ownership has positive effects on proxies of earnings quality. Nonetheless, passive institutional ownership does not have any power to affect earnings quality. Moreover, lead-lag tests of the direction of causality suggest that institutional ownership leads to more earnings quality and not the reverse.     

Management Earnings Forecasts,Earnings Announcements,and Institutional Trading in China

Abstract:

In this study, we investigate the trading behavior of institutional investors in China according to management earnings forecasts (MEFs) and earnings announcements (EAs). MEFs are mandatory under the stringent regulatory framework in China. We find evidence that both MEFs and EAs have an effect on the market. However, MEFs have a bigger effect on the market than do EAs. According to a sample of semiannual observations of firms from 2003 to 2008, we find that changes in the stock ownership of institutions are positively associated with EAs but not significantly associated with MEFs. When we further examine the relations between institutional characteristics and trading strategies, we find that growth funds exploit the arbitrage opportunity of MEFs.

Institutional Logics and Responses to Performance Measurement Systems

Abstract: This comparative study analyzes institutional logics and categorizes organizational responses to performance measurement systems (PMSs) in two Finnish cities. We refine the typology of organizational responses and suggest how the choice of response depends on the institutionalized logic in the public sector accounting context (cf. Oliver, 1991 ). Further, we discuss and refine the types of successful co‐operation under competing institutional logics (cf. Reay and Hinings, 2009 ). Our study also sheds light on practice variation in public sector accounting such as how and why PMS use materializes in different forms in units with different institutional logics.     

The Effect of Earnings–Announcement Timing on Earnings Management

This paper examines whether firms which delay earnings announcements engage in earnings management. The cross–sectional version of the modified Jones 1995 model is used to estimate 'normal' accruals. Prior research has documented that, on average, delayed earnings announcements are associated with negative earnings surprises. Our evidence suggests that the market anticipates unfavorable earnings news when it observes reporting delays. As a consequence, late reporters appear to make the most of a bad situation by employing income–decreasing accruals in big–bath–type earnings management and in contractual renegotiations. We find that the magnitude of income–reducing abnormal accruals is related to the reporting lag.

Firm Size and the Information Content of Annual Earnings Announcements: Australian Evidence

Abstract:   We investigate the effect of firm size on the market's short‐window response to annual earnings announcements for a large sample of Australian listed companies. Our research design involves regressions of unexpected earnings against unexpected returns. Non‐linearity in the returns‐earnings relationship is incorporated and other factors known to affect the response to earnings announcements are controlled for. Contrary to prior US research, our results show that firm size has either no effect on the response to earnings announcements (3 day window) or the response is significantly stronger for larger firms (twenty‐one day window). The information content of earnings announcements is present across firm size categories but the nature of the response differs with firm size and context.     

Evidence that Analyst Following and Institutional Ownership Accelerate the Pricing of Future Earnings

This paper presents evidence that prices of firms followed by sell-side analysts and favored by institutional investors incorporate future earnings earlier than prices of other firms. We conduct two sets of empirical tests: the first examines coefficients from regressions of returns on lead, contemporaneous, and lag earnings changes; the second compares the timing of monthly abnormal returns from earnings-based zero-investment portfolios. In both sets of tests, the results for analysts and institutions are incremental to each other. In addition, neither the analyst price lead nor the institutional price lead is due to price leads increasing with firm size.
