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。     

信息披露、信息不对称和资本成本:研究综述

信息披露对资本成本的影响是会计领域的一个基本问题,也是经济金融领域的一个重要问题。不同领域的很多文献都从不同方面考察了信息披露对资本成本的影响,但是目前还没有形成一套有机的关于信息披露影响资本成本的理论。为了更好的指导未来的研究,本文将这些文献进行简要总结,旨在形成一套指导研究的理论框架。贯穿这个研究框架的理论逻辑就是信息披露通过影响信息不对称来影响资本成本。最后,本文还给出了一些未来研究建议。     

会计稳健性、信息不对称与股权融资成本

本文以沪深股市2006—2015年非金融行业上市公司为初始样本,结合我国的产权性质,考察了会计稳健性与股权融资成本的关系,并采用中介效应分析方法,探讨了会计稳健性对股权融资成本的可能影响路径。研究发现:第一,会计稳健性与股权融资成本负相关,信息不对称水平是会计稳健性影响股权融资成本的一个中介变量。第二,相对于国有企业,非国有企业会计稳健性对股权融资成本的降低作用更加显著。     

资本市场会计信息披露暨治理问题研究--基于上市公司会计信息披露不对称的视角

上市公司会计信息生产和披露质量直接影响了资本市场的稳定健康发展。资本市场会计信息生产和披露存在着一定的供求机理,直接影响了会计信息生产和披露的质量。由于管理主体上的虚化、内控弱化和治理结构上的偏差、会计信息系统的集成和共享性弱以及从业人员素质上的差异,使得上市公司会计信息披露存在着不充分性、非主动性、虚假性和滞后性问题,由此增加了资本市场信息不对称和风险发生的可能。因此,严厉打击资本市场会计信息造假,规范资本市场会计信息披露,需要进一步完善资本市场会计信息披露制度,创新和完善新技术背景下会计准则和会计制度,加强对现有上市公司会计信息生产和会计信息披露标准的制定和使用,提升上市公司会计信息生产和会计信息披露独立审计监督的标准化和规范化水平,加强上市公司会计信息生产和披露监督标准化体系建设。     

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.     

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.     

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.     

碳信息披露、碳业绩与资本成本

为应对气候变化挑战,越来越多企业自愿披露碳信息。本研究考察碳信息披露、碳业绩与资本成本之间关系。利用联立方程模型和标准普尔500企业样本,我们发现:资本成本与碳信息披露负相关,这符合自愿披露理论预测。而且,对于碳业绩好的企业,这个负相关关系更弱。我们还发现,碳信息披露与碳业绩负相关,这与合法性理论预测一致。研究表明,碳信息披露是企业的理性选择。企业披露碳信息旨在减轻合法性压力,降低资本成本。     

Voluntary Disclosure, Earnings Quality, and Cost of Capital

We investigate the relations among voluntary disclosure, earnings quality, and cost of capital. We find that firms with good earnings quality have more expansive voluntary disclosures (as proxied by a self‐constructed index of coded items found in 677 firms' annual reports and 10‐K filings in fiscal 2001) than firms with poor earnings quality. In unconditional tests, we find that more voluntary disclosure is associated with a lower cost of capital. However, consistent with the complementary association between disclosure and earnings quality, we find that the disclosure effect on cost of capital is substantially reduced or disappears completely (depending on the cost of capital proxy) once we condition on earnings quality. Extensions probing alternative proxies show that our findings are robust to measures of earnings quality and cost of capital, but not to other measures of voluntary disclosure. In particular, we find opposite relations for voluntary disclosure measures based on management forecasts and conference calls, and we find no relations for a press release based measure.     

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。     

Cost of Capital, Strategic Disclosures and Accounting Choice

Abstract:   Theory suggests a negative relationship between disclosure and the cost of capital. However, empirical research has not, in general, confirmed this. In particular, Botosan (1997) finds no evidence of a negative relationship for firms with a high analyst following, and moreover, Botosan and Plumlee (2002a) find that firms' cost of capital increases with timely disclosures. There are several possible explanations for this puzzle. First, the theory‐driven hypothesis may be false and require re‐specification. Second, there may be correlated omitted variables contaminating the results. Finally, these inconclusive results may have arisen due to problems with the measurement of disclosure. We construct an innovative measure of timely disclosure, that attempts to capture quality rather than quantity of strategic disclosures. In addition, motivated by new theoretical research by Gietzmann and Trombetta (2003) , we control for a possible omitted variable, namely accounting policy choice. With this revised research design, we find the expected negative relationship. Furthermore, as predicted by Gietzmann and Trombetta, this relationship is only significant for firms adopting aggressive accounting policies.     

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.     

Information and the Cost of Capital

We investigate the role of information in affecting a firm's cost of capital. We show that differences in the composition of information between public and private information affect the cost of capital, with investors demanding a higher return to hold stocks with greater private information. This higher return arises because informed investors are better able to shift their portfolio to incorporate new information, and uninformed investors are thus disadvantaged. In equilibrium, the quantity and quality of information affect asset prices. We show firms can influence their cost of capital by choosing features like accounting treatments, analyst coverage, and market microstructure.     

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。

资本成本会计新探

传统会计只确认债务资本成本，不确认股权资本成本，这种“成本”是不完善的，未能体现公司作为会计主体的理念。应建立资本成本会计，完善资本成本理念。
