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。  

Shareholder rights, financial disclosure and the cost of equity capital

This study extends research into whether shareholder rights and disclosures of financial-related attributes are associated with firms' costs of equity capital. Using cost-of-equity-capital estimates derived from expected earnings growth valuation models, we find that firms with stronger shareholder rights regimes and higher levels of financial transparency are associated with significantly lower costs of equity capital. We also find evidence that greater financial disclosure and stronger rights regimes interact in reducing firms' costs of equity capital, such that the effect of a high level of one mechanism is minimal when it is combined with a low level of the other. Finally, we document that neither factor dominates the other in their associations, and that there are tradeoffs between disclosure levels and shareholder rights in their influence on firms' implied costs of equity capital.

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。  

Economic Benefits of Adopting IFRS or US‐GAAP – Have the Expected Cost of Equity Capital Really Decreased?

Abstract:   The question of whether the adoption of International Financial Reporting Standards (IFRS) results in measurable economic benefits is of special interest, particularly in light of the European Union's adoption of IFRS for listed companies. In this paper, I investigate the common conjecture that internationally recognised financial reporting standards (IAS/IFRS or US‐GAAP) reduce the cost of capital for adopting firms. Building on Leuz and Verrecchia (2000) , I use a set of German firms that have adopted such standards and investigate the potential economic benefits of this reporting strategy by analysing their cost of equity capital through the use and customisation of available implied estimation methods. Evidence from the 1993–2002 period fails to document lower expected cost of equity capital for firms applying IAS/IFRS or US‐GAAP. During the transition period I analyse, the expected cost of equity capital in fact appear to have rather increased under non‐local accounting standards.  

Alternative Models for Estimating the Cost of Equity Capital for Property/Casualty Insurers

This paper estimates the cost of equity capital for Property/Casualty insurers by applying three alternative asset pricing models: the Capital Asset Pricing Model (CAPM), the Arbitrage Pricing Theory (APT), and a unified CAPM/APT model (Wei (1988). The in-sample forecast ability of the models is evaluated by applying the mean squared error method, the Theil U2 (1966) statistic, and the Granger and Newbold (1978) conditional efficiency evaluation. Based on forecast evaluation procedures, the APT and Wei's unified CAPM/APT models perform better than the CAPM in estimating the cost of equity capital for the PC insurers and a combined forecast may outperform the individual forecasts.

The effect of management earnings forecast characteristics on cost of equity capital

This study uses a framework presented in Hirst, Koonce, and Venkataraman (2008) to assess how differences in management earnings forecast characteristics influence a firm's cost of equity capital. I find that less specific forecasts, pessimistic forecasts, and forecasts that predict a loss for the period are associated with higher cost of equity capital levels and more timely forecasts and forecasts with more information content are associated with lower cost of equity capital levels. Analysis interacting control variables and forecast antecedents with forecast characteristics indicates that the effects forecast characteristics have on cost of equity capital are either enhanced or moderated depending on firm beta, firm size, firm book-to-market ratios, analyst following, prior forecast bias, and earnings quality. The results highlight the importance of interacting key variables when interpreting the market effect of management earnings forecasts.  

Stock splits, trading continuity, and the cost of equity capital

We hypothesize that managers use stock splits to attract more uninformed trading so that market makers can provide liquidity services at lower costs, thereby increasing investors’ trading propensity and improving liquidity. We examine a large sample of stock splits and find that, consistent with our hypothesis, the incidence of no trading decreases and liquidity risk is lower following splits, implying a decline in latent trading costs and a reduced cost of equity capital. Further, split announcement returns are correlated with the improvements in both liquidity levels and liquidity risk. Our analysis suggests nontrivial economic benefits from liquidity improvements, with less liquid firms benefiting more from stock splits.  

Discussion of ‘Accounting Premium’ for IAS/IFRS and U.S. GAAP Vis-à-vis German GAAP”

Ernstberger and Vogler [Ernstberger, J. & Vogler, O. (2008-this issue). Analyzing the German Accounting Triad with an Enhanced Multifactor Model—‘Accounting Premium’ for IAS/IFRS and U.S. GAAP Vis-à-vis German GAAP. International Journal of Accounting.] employ the concurrent use of three distinct accounting-standard regimes (German GAAP; U.S. GAAP; and IAS/IFRS GAAP) in Germany as a foundation for evaluating the relation between accounting standard regime and equity-return attributes. They find that firms using U.S. or IAS/IFRS GAAP have higher betas but yield lower returns (cost of capital) relative to firms employing German GAAP. They also find that portfolios designed to isolate the return impacts of U.S. and IAS/IFRS GAAP relative to German GAAP are priced in a risk-factor-like fashion. In this discussion I suggest that a good bit of this empirical evidence is problematic. I also discuss the implausibility of information quality being priced in a Fama and French [Fama, E.F. & French, K.R. (1992). The Cross-Section of Expected Stock Returns. The Journal of Finance 47 (2): 427–465.] factor-like fashion. Finally, I introduce the importance of conditioning analyses of the relation between firm-level information quality and equity-market return (cost of capital) on the degree to which the shareholder base of a firm holds diversified portfolios.
