企业社会责任信息披露与权益资本成本

运用理论分析和实证检验的方法从权益资本成本的角度研究我国上市公司企业社会责任信息披露的经济动机.研究发现:上市公司上期权益资本成本越高,本期披露社会责任报告的可能性越大,说明降低权益资本成本是上市公司决定是否披露社会责任报告的重要经济动机;对于首次披露企业社会责任报告的公司,上期权益资本成本越高,本期社会责任信息披露质量越高;但对非首次披露企业社会责任报告的公司来说,披露企业社会责任报告的资本成本动机不显著.     

智力资本信息披露对股权资本成本的影响

本文利用智力资本信息披露大样本数据,研究智力资本信息披露对股权资本成本的影响机制.研究表明:(1)总体智力资本、人力资本信息披露与股权成本负相关.(2)相对于内控质量较低的企业,内控质量高的企业披露智力资本与人力资本信息,能够更有效地降低股权成本.(3)与竞争缓和环境中的企业相比,激烈竞争环境中的企业的智力资本、人力资本信息披露对股权成本的降低作用更强.此外,总体智力资本、人力资本信息披露能够通过缓解信息不对称、减少买卖价差的中介路径发挥降低股权成本的作用.     

市场化进程、自愿性信息披露和权益资本成本

基于市场化进程中政府对企业干预程度的差异,本文研究市场化进程对自愿性信息披露与权益资本成本关系的影响。研究发现,市场化进程对自愿性信息披露与权益资本成本的负相关关系起加强作用;更进一步地,在市场化进程较低的地区,受较强的政府干预的影响,国有上市公司比非国有上市公司自愿性信息披露与权益资本成本的相关关系更弱,相反,在市场化进程较高的地区,政府会减少对企业的干扰,非国有上市公司相比于国有上市公司对这种影响的弹性更大,表现在非国有上市公司比国有上市公司更能通过披露较多的自愿性信息来降低权益资本成本。     

信息披露、收益不透明度与权益资本成本

本文以1993年至2001年间我国证券市场进行股权再融资的上市公司为样本,深入考察我国证券市场上市公司信息披露质量与公司权益资本成本的关系。结果表明,在控制其他一些影响因素之后,上市公司信息披露质量与公司权益资本成本呈显著的负相关关系;对上市公司而言,提高信息披露的质量有助于降低公司的权益资本成本。同时,本文还发现,上市公司权益资本成本不仅受到前一年信息披露质量的影响,还受到前四年信息披露质量的影响。所以,上市公司管理者为了降低公司再融资的权益资本成本,应该持之以恒地致力于保持较高的信息披露质量。     

内部控制报告与权益资本成本的关系研究

以2007～2009年沪深两市A股上市公司为研究样本,基于信息披露能够缓解信息不对称进而降低权益资本成本的分析检验了内部控制报告披露与企业权益资本成本的关系。结果发现企业内部控制报告的披露未对权益资本成本产生影响。无论是出于自愿或是基于监管要求披露内部控制报告,也无论是仅出具内控自评报告或是引入独立第三方另出具内控审计报告,企业的内部控制报告披露行为均未对权益资本成本产生影响。研究结果表明企业没有实现内部控制报告的有效披露。     

Disclosure Interactions and the Cost of Equity Capital: Evidence From the Spanish Continuous Market

Abstract:  The purpose of this paper is to provide some new evidence on the relationship between disclosure and the cost of equity capital. We propose a new specification for the empirical test based on the idea that in the previous models one crucial variable was missing: accounting policy choice. We test our theoretical hypothesis using a sample of Spanish firms quoted on the Spanish continuous market from 1999 to 2002. We adopt the ex-ante approach to measure the cost of equity capital, taking analysts predictions as a proxy for expected earnings. As an explanatory variable we use an index measuring annual report disclosure quality. This measure of disclosure is combined with a proxy for the accounting policy choice of the firm. We measure firms' conservatism using the modified Jones model of Dechow et al. (1995) to estimate discretionary accruals. Our results confirm that the relationship between disclosure and cost of capital is affected by the choice of accounting policy.     

Segment Disclosure and Cost of Capital

We investigate whether segment disclosure influences cost of capital. Improved segment reporting is expected to decrease cost of capital by reducing estimation risk. However, in a competitive environment segment disclosure may also generate uncertainties about future prospects and lead to a larger cost of capital. Asset‐pricing tests confirm that segment disclosure is a priced risk factor. Also, segment disclosure reduces ex‐ante estimates of cost of equity capital and other measures connected to risk. These results suggest a negative relation between segment disclosure and cost of capital. Our results also show that competition reduces, but does not eliminate, the previous relationship.     

Quality of Corporate Social Responsibility Disclosure and Cost of Equity Capital: Lessons from China

This article explores the relationship between the quality of corporate social responsibility (CSR) disclosure and the cost of equity capital by analyzing the financial data and CSR reports of A-share listed firms in China from 2008 to 2014. The quality of the CSR disclosure is shown to be negatively related to the cost of equity capital of the listed firms. This negative correlation proves to be more prominent among firms of environmentally sensitive industries. Taking the ownership of the listed firms into consideration, it is further confirmed that the negative relationship between the CSR disclosure and the cost of equity capital is of higher significance for state-owned enterprises. Our findings also empirically demonstrate that the quality of CSR disclosure is more negatively related to the cost of equity capital among the large listed firms than the smaller ones.     

股权激励、管理者过度自信与权益资本成本

基于行为金融的视角,从管理者过度自信角度解释了我国股权激励计划实施效果不佳的困惑。实证结果表明,我国实施股权激励计划会在高管过度自信的条件下对上市公司权益资本成本产生影响：股权激励计划的实施提高了上市公司高管过度自信水平;股权激励与高管过度自信的相互作用使得上市公司权益资本成本显著升高。这意味着从管理者过度自信的角度考察股权激励对企业权益资本成本造成的影响,可能会更好地解释股权激励的价值效应。     

论信息披露程度对权益资本成本的影响——基于深圳证券交易所相关数据的实证分析

本文基于深圳证券交易所公布的对于主板和中小板上市公司信息披露程度的评估,CSMAR数据库中有关上市公司流通股数、年末收盘价及总资产等基本数据资料,以及wind网站上有关股票β系数的数据,运用反求折现率的方法得到权益资本成本的估计值,进而对信息披露程度、企业风险与权益资本成本的关系进行了深入研究.结果表明:上市公司信息披...     

Disclosure,Liquidity, and the Cost of Capital

This paper shows that revealing public information to reduce information asymmetry can reduce a firm's cost of capital by attracting increased demand from large investors due to increased liquidity of its securities. Large firms will disclose more information since they benefit most. Disclosure also reduces the risk bearing capacity available through market makers. If initial information asymmetry is large, reducing it will increase the current price of the security. However, the maximum current price occurs with some asymmetry of information: further reduction of information asymmetry accentuates the undesirable effects of exit from market making.     

媒体曝光度、信息披露环境与权益资本成本

媒体发挥着公司治理和信息传播的双重作用,这有助于减少投资者与公司间的信息不对称,而信息不对称程度的降低会减少公司的融资成本。本文选取2007年之前上市A股公司为样本,实证检验了媒体曝光度对权益资本成本的影响。研究发现媒体报道有助于降低公司权益资本成本。研究还进一步发现在市场化程度越低的地区,媒体报道对权益资本成本的影响力越强;在非国有企业中,机构投资者持股比例越高,媒体报道对权益资本成本的影响力越强。     

投资者保护与权益资本成本的关系探讨

本文以沪深两市2003年576家上市公司为研究样本，以权益资本成本为因变量，以本文所构建的投资者保护指数为自变量，运用多元回归方法对两者关系进行检验分析。研究发现：投资者保护与权益资本成本呈显著负相关关系，即使在考虑了公司规模、Beta系数、行业影响等因素后，两者之间的负相关关系仍然显著，这就证明我国上市公司虽然整体投资者保护水平不高，但公司之间的保护程度仍有重大差异；我国证券市场上的投资者已经能够在一定程度上区别对待投资者保护水平不同的上市公司。     

Institutional Investment Horizons and the Cost of Equity Capital

We examine the influence of institutional investors’ investment horizons on a firm's cost of equity. We argue that the cost of equity will decrease in the presence of institutional investors with longer‐term investment horizons due to improved monitoring and information quality. Our empirical results demonstrate that the cost of equity declines in the presence of institutional investors with long‐term investment horizons, all else remaining equal. Our results indicate also that the monitoring role of long‐term institutional investors is more pronounced for firms with higher agency problems (poorly governed firms). Overall, our evidence suggests that when considering the influence of institutional investors, it is critical to account for institutional heterogeneity, which leads to new directions for future research.     

Disclosure and the Cost of Capital: A Survey of the Theoretical Literature

This article offers a survey of theoretical research on disclosure and the cost of capital. We summarize the current state of the literature and discuss the channels through which information affects the cost of capital. After giving an overview of asset pricing theory, we examine the rationale for an accounting risk factor or an ex‐ante effect of information on the cost of capital. Then, we discuss the role of voluntary disclosure, heterogenous beliefs, investor base, liquidity shocks, earnings management, and agency problems as determinants of the cost of capital. Linkages between productive decisions and the cost of capital, and their implication for investor welfare, are also examined.     

Environmental Disclosure and the Cost of Equity: The French Case

What is the impact of voluntary corporate environmental disclosures on the cost of equity? The present study will attempt to answer this question. The empirical research is based on companies listed in the French SBF 120 stock market index. In 2006, most of these companies devoted a section of their annual report to environmental actions, yet fewer than 20% of them actually published a separate report dedicated to the issue of sustainable development. Regardless of the selected medium, the environmental topics receiving the most attention in corporate reporting are pollution, natural resources and recycling. The determinants associated with environmental disclosure are: company size, financial leverage, and the number of financial analysts monitoring company stock. This study does not lead to concluding that companies disclosing environmental information necessarily lower the cost of equity.     

Dividend Taxes and Implied Cost of Equity Capital

We estimate firm‐level implied cost of equity capital based on recent advances in accounting and finance research and examine the effect of dividend taxes on the cost of equity capital. We investigate whether dividend taxes affect firms' cost of capital by testing the relation between the implied cost of equity capital and a measure of the tax‐penalized portion of dividend yield, which we define as the product of dividend yield and the dividend tax penalty. The results generally support the dividend tax capitalization hypothesis. We find a positive relation between the implied cost of equity capital and the tax‐penalized portion of dividend yield that is decreasing in aggregate institutional ownership, our proxy for tax‐advantaged investors. The evidence in this study adds to the understanding of the effect of investor‐level taxes on equity value.     

Accounting Information, Disclosure, and the Cost of Capital

In this paper we examine whether and how accounting information about a firm manifests in its cost of capital, despite the forces of diversification. We build a model that is consistent with the Capital Asset Pricing Model and explicitly allows for multiple securities whose cash flows are correlated. We demonstrate that the quality of accounting information can influence the cost of capital, both directly and indirectly. The direct effect occurs because higher quality disclosures affect the firm's assessed covariances with other firms' cash flows, which is nondiversifiable. The indirect effect occurs because higher quality disclosures affect a firm's real decisions, which likely changes the firm's ratio of the expected future cash flows to the covariance of these cash flows with the sum of all the cash flows in the market. We show that this effect can go in either direction, but also derive conditions under which an increase in information quality leads to an unambiguous decline in the cost of capital.     

Taxes, Leverage, and the Cost of Equity Capital

We examine the associations among leverage, corporate and investor level taxes, and the firm's implied cost of equity capital. Expanding on Modigliani and Miller [1958, 1963] , the cost of equity capital can be expressed as a function of leverage and corporate and investor level taxes. Based on this expression, we predict that the cost of equity is increasing in leverage, and that corporate taxes mitigate this leverage‐related risk premium, while the personal tax disadvantage of debt increases this premium. We empirically test these predictions using implied cost of equity estimates and proxies for the firm's corporate tax rate and the personal tax disadvantage of debt. Our results suggest that the equity risk premium associated with leverage is decreasing in the corporate tax benefit from debt. We find some evidence that the equity risk premium from leverage is increasing in the personal tax penalty associated with debt.     

Estimating the Cost of Equity Capital for Property-Liability Insurers

This article presents new evidence on the cost of equity capital by line of insurance for the property‐liability insurance industry. To do so we obtain firm beta estimates and then use the full‐information industry beta (FIB) methodology to decompose the cost of capital by line. We obtain full‐information beta estimates using the standard one‐factor capital asset pricing model and extend the FIB methodology to incorporate the Fama–French three‐factor cost of capital model. The analysis suggests the cost of capital for insurers using the Fama–French model is significantly higher than the estimates based upon the CAPM. In addition, we find evidence of significant differences in the cost of equity capital across lines.
