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。     

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.     

Industry Cost of Equity Capital: UK Evidence

Abstract:  This paper explores the industry cost of equity capital for the UK. We replicate the Fama and French (1997) US analysis for UK industries, but additionally investigate the industry cost of equity capital obtained from a conditional CAPM, the Cahart (1997) four factor model, and the Al-Horani, Pope and Stark (2003) R&D model. In line with the Fama-French US results, the out of sample performance of all the models is disappointing Whilst the FF3F model has a somewhat higher explanatory power than the CAPM in terms of explaining past returns, the SMB and HML factor slopes show considerable variability through time. However, all our models of the cost of equity capital in the UK outperform a simple 'beta one' model, a result that has implications for the regulatory process. There is also some evidence to suggest that a conditional CAPM may be of interest to regulators. The new R&D model of Al-Horani et al. clearly has potential, in that over the limited period for which data is available it yields return errors not dissimilar to those found under the FF3F model, but exhibits slope coefficients on the fourth R&D factor that seem to be relatively stable.     

Disclosure and the Cost of Capital: Evidence from the Market's Reaction to Firm Voluntary Adoption of IAS

Abstract:  Using a unique international setting where the effects of disclosure on firm value can be measured in a constant regulatory environment and in isolation of other confounding factors, this paper shows that firms can increase their value through their choice of accounting standards. Specifically, we document strong positive abnormal returns at the announcement of voluntary adoption of International Accounting Standards (IAS / IFRS) by a sample of international firms and an economically significant reduction in long-run returns, consistent with a reduction in the cost of capital. Consistent with these results we also document evidence of an upgrade in analyst recommendations after the IAS / IFRS adoption announcement and a reduction in the implied cost of capital. Finally, we find strong evidence that the documented abnormal returns are consistent with signaling and bonding benefits stemming from the reduction in asymmetric information. Our results highlight the importance of increased disclosure on minority shareholder protection and on corporate governance in general.     

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.     

Time Varying Market Leverage, the Market Risk Premium and the Cost of Capital

This paper shows that, when as usual the market portfolio is proxied by a share portfolio, then the conventional Ibbotson (1999) estimator of the market risk premium violates Miller–Modigliani (1958 and 1963) propositions II and III. A new estimator of the market risk premium is proposed which is free of these defects. In addition, across the range of market leverages experienced in the US in the period 1952–1997, it generates estimates of the market risk premium that differ from those generated by the Ibbotson methodology by up to 2.5 percentage points, and weighted average costs of capital for firms that differ by up to 2.6 percentage points.     

Use of Forecasts of Earnings to Estimate and Compare Cost of Capital Across Regimes

Abstract:   I critically examine several of the methods used in the recent literature to estimate and compare the cost of capital across different accounting/regulatory regimes. I focus on the central importance of expectations of growth beyond the short period for which forecasts of future pay‐offs (dividends and/or earnings) are available. I illustrate, using the stocks that comprised the Dow Jones Industrial Average (DJIA) at December 31, 2004, as an example, the differences between the growth rates implied by the data, and growth rates that are often assumed in the literature. My analyses show that assumptions about growth beyond the (short) forecast horizon may seriously affect the estimates of the expected rate of return and may lead to spurious inferences.     

Accruals Quality, Information Risk and Cost of Capital: Evidence from Australia

Abstract:  Recent theoretical work argues that information risk is a non-diversifiable risk factor that is priced in the capital market. Using accruals quality to proxy for information risk, Francis et al. (2005) provide empirical support for this argument using a sample of US firms. This paper re-examines the interplay of accruals quality, information risk and cost of capital in Australia, where a number of important institutional and regulatory differences are hypothesized to affect the relation between accruals quality and cost of capital. The results suggest that, while accruals quality impacts on the cost of capital for Australian firms, some salient differences exist. In contrast to findings for US firms, the costs of debt and equity for Australian firms are largely influenced by accruals quality arising from economic fundamentals (i.e., innate accrual quality) but not discretionary reporting choices (i.e., discretionary accrual quality). This finding is consistent with our predictions based on the Australian institutional and regulatory environment. In addition, using both the asset pricing tests in Francis et al. (2005) and Core et al. (2008) , we provide evidence consistent with accruals quality being a priced risk factor.     

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。     

The Effect of Regulatory Announcements on the Cost of Equity Capital of British Telecom

This paper examines the impact of regulatory announcements which affect competition, pricing policy and the supply of services in the telecommunications industry on British Telecom's (BT) systematic risk, as measured by the beta coefficient of a market model. Changes in investors' perception of a company's systematic risk will of course also change its cost of equity capital. Since BT's beta coefficient is found to be unstable over the estimation period, the market model is estimated using a time-varying parameter model. The results suggest that announcements which allow the price of BT's services to increase and announcements affecting its supply of services are likely to have an impact on BT's cost of equity capital, since they affect the investor's perception of BT's systematic risk. However, our analysis does not detect any effect from the other types of announcements tested. Further examination of the individual announcements included in the groups reveals that, within the non-significant groups, many individual announcements are significant, but they affect beta in opposite directions and thus no prediction can be made on the sign of their aggregated impact. These findings suggest that when one company dominates the industry, such as in the case of the UK telecommunications industry, the actions of the regulator do not always have the expected effect and problems of regulatory capture are likely to be present.     

Taxation, Uncertainty, and the Cost of Equity

Traditionally the pre-tax cost of capital is a function of the interest rate and the tax system. However, uncertainty implies that the market's required return is no single interest rate, but depends on risk. Different tax systems split risk differently between firm and government. Thus the required expected return after corporate taxes depends on the tax system. Expressions for this are derived, based on a CAPM-type model. The weighted average cost of capital is decreasing in the tax rate, even for fully equity financed projects. This effect can be substantial, but is neglected in much of the literature.     

Information and the Cost of Capital in a Mean‐Variance Efficient Market

Before information ? arrives, market observers must be uncertain whether the stock price conditioned on ? will be higher or lower than the current price. Otherwise there is an obvious arbitrage opportunity. By assuming this minimal condition of efficient markets, it is shown under the mean‐variance CAPM that information that leaves the future value of a firm more certain, in the sense that its perceived covariance with the market is reduced towards zero, can lead to a higher expected return on that asset. A further result is that it is theoretically possible that the required return on the stock will necessarily fall after observing signal ?, or (in other circumstances) that it will necessarily rise. In general, information that allows better discrimination between firms leads some firms to have higher costs of capital and other firms to have lower costs of capital. Less obviously, better discrimination between firms can induce a higher average cost of capital across the market.     

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.

The Cost of Equity Capital at the Corporate and Investor Levels Allowing a Rational Expectations Model with Personal Taxations

This paper argues that the conventional definition of the cost of equity at the corporate level is likely to be fundamentally flawed under conditions of personal taxation. A 'dimensionally consistent' definition is developed utilising the pioneering contributions of Auerbach and Elton and Gruber. Consequent benefits are straight-forward expressions for the cost of equity capital at the corporate level (for both retained earnings and new equity) as well as at the investor level (post personal tax) in terms of both the dividend discount and CAPM-type models, which are applicable to classical and imputation tax systems. A fundamental framework is thereby provided which succeeds in illuminating investor pesonal tax liabilities as they might be expected to impact on a firm's investment and related dividend policies.     

Inferring the Cost of Capital Using the Ohlson–Juettner Model

We compare risk premia (RP) inferred using the Ohlson-Juettner (RP_OJ) and residual income valuation (RP_RIV) models in three ways: (1) correlation with risk factors; (2) correlation with RP estimated by multiplying current realizations of risk factors by coefficients obtained from regressing prior-year RP on prior-year risk factors; and (3) correlation with ex post returns. RP_OJ has expected correlations with risk factors, a modest correlation with RP estimated from prior-year regressions, and an economically significant association with ex post returns. RP_RIV has generally higher correlations, but regression coefficients are sensitive to whether the industry median ROE is computed with or without loss firms.     

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。     

Financial Restatements, Cost of Debt and Information Spillover: Evidence From the Secondary Loan Market

Abstract:  In this paper, we investigate the effect of financial restatements on the debt market. Specifically, we focus on the secondary loan market, which has become one of the largest capital markets in the US, and ask the following: (1) whether financial restatements increase restating firm's cost of debt financing and (2) whether the information about restatements arrives at the secondary loan market earlier than at the stock market? Using 176 restatement data, we find significant negative abnormal loan returns and increased bid-ask spreads around restatement announcements. Furthermore, this negative loan market reaction is more pronounced when the restatement is initiated by either the SEC or auditors, and when the primary reason for restatement is related to revenue recognition issues. Additionally, we find restatement information arrives at the secondary loan market earlier than at the equity market, and that such private information quickly flows into the equity market. We also show that stock prices begin to decline approximately 30 days prior to the restatement announcements for firms with traded loans. However, we do not find such informational leakage for firms without traded loans. Collectively, the results of this paper suggest: (1) increased cost of debt financing after restatements and (2) superior informational efficiency of the secondary loan market to the stock market.     

基于资本成本的股利决策分析

在委托代理关系和信息不对称条件下,公司经理应以资本成本决策股利支付,贯彻资本成本观念。公司经理资本成本观念是在资本成本作用机制下形成的,需要具备一定的条件。我国上市公司股利支付的随意性表明,公司经理缺乏资本成本观念,其原因在于资本成本作用机制所要求的条件不具备,因此,规范上市公司股利支付行为应从健全资本成本作用机制所要求的条件入手。     

Stock Price Reaction to Evidence of Earnings Management: Implications for Supplementary Financial Disclosure

We condition security price reactions to quarterly earnings announcements on whether firms disclose supplementary balance sheet and/or cashflow information that can be used to estimate the consequences of earnings management. Disclosure of supplementary information is voluntary, and thus, we consider the possibility that firms that disclose balance sheet and/or cashflow information differ systematically from firms that do not disclose. Results indicate that investors discount evidence of earnings management at the disclosure date when supplementary information is disclosed. Such results indicate more informed earnings interpretations of quarterly earnings when firms provide balance sheet and/or cashflow information concurrently.
