财务重述公司盈余反应系数研究——基于中国上市公司年报财务重述的经验证据

GAO(2002)的研究报告指出,投资者对财务报告的信心是证券市场有效运作的重要保证。近年来,财务重述现象在国内外呈现出蔓延局势,国外一系列研究表明财务重述对公司价值产生负面影响,而比短期的市场价值受损更可怕的是投资者对重述公司的信任度大打折扣,对整个资本市场的信心下降。中国上市公司的重述现象也不容乐观,但是对于财务重述经济后果的研究相对较少。因此本文主要考察重述报告对重述公司的盈余反应系数的影响,通过理论分析与数据检验投资者对财务重述公司盈余信息的反应程度,研究发现重述公告使重述公司特别是涉及核心会计指标重述公司盈余反应系数降低。以期通过本文的研究为上市公司敲响警钟,并为监管部门对财务重述行为进行规范监管提供经验证据。     

Accounting Losses and Earnings Response Coefficients: The Impact of Leverage and Growth Opportunities

This paper investigates how accounting losses affect the relationship between accounting earnings and stock returns, i.e. earnings response coefficients (ERCs), in different leverage and growth categories. In a sample of NYSE firms between 1975 and 1990, the exclusion of losses improves the ERCs considerably. While the impact of losses on ERCs is highest in the subgroup including high growth opportunity firms, the exclusion of losses does not improve ERCs as significantly among firms with low growth opportunities. The results further support the hypothesis that the impact of losses on ERCs is different in different financial leverage subgroups. The measured increase in ERCs is most significant among the least levered firms. The observation that the impact of losses on ERCs is related to growth opportunities and financial leverage is clearly observable also in different size categories. The effects of growth opportunities and financial leverage are also incrementally important with respect to each other. In general, the results indicate that the impact of growth opportunities and financial leverage on ERCs is clearly observable especially when losses and profits are analyzed separately.     

Income Smoothing, Earnings Quality and Firm Valuation

Abstract:   This study argues that lower variability of earnings does not guarantee income smoothers' higher firm values. Instead, smoothers' earnings should be more value‐relevant if they are of high quality, i.e., earnings quality should be considered simultaneously. Sample firms are divided into four groups: quality earnings smoothers, quality earnings non‐smoothers, non‐quality earnings smoothers, and non‐quality earnings non‐smoothers. Value relevance of reported earnings is then studied using both the levels and the changes approaches with indicator variables. Results show quality earnings smoothers have the highest price‐earnings multiple while non‐quality non‐smoothers have the lowest price‐earnings multiple.     

Earnings Surprises,Growth Expectations,and Stock Returns or Don't Let an Earnings Torpedo Sink Your Portfolio

We provide new evidence that the inferior returns to growth stocks relative to value stocks are the result of expectational errors about future earnings performance. Our evidence demonstrates that growth stocks exhibit an asymmetric response to earnings surprises. We show that while growth stocks are at least as likely to announce negative earnings surprises as positive earnings surprises, they exhibit an asymmetrically large negative price response to negative earnings surprises. After controlling for this asymmetric price response, we find no remaining evidence of a return differential between growth and value stocks. We conclude that the inferior return to growth stocks is attributable to overoptimistic expectational errors that are corrected through subsequent negative earnings surprises.     

Information Content of Interim Earnings Components—Evidence from Finland

This study examines the information content of the interim earnings of listed Finnish firms. The degree of association between returns and interim earnings is studied. The assumption is that, compared to transitory changes, permanent changes in earnings have a greater association with returns. Unexpected returns are regressed over unexpected permanent earnings and unexpected transitory earnings. Three return measurement periods are used to examine any potential asynchrony between prices and earnings. To reduce the errors-in-variables problem expected in single-security-level studies, observations are grouped into portfolios. When the data are divided into portfolios, the results give evidence of the association as hypothesized.     

On the Market Reaction to Revenue and Earnings Surprises

Abstract:  This study extends Ertimur et al. (2003) and Jegadeesh and Livnat (2006a) by providing a contextual framework for the information content of revenue and earnings surprises. I find that the influence of earnings surprises (revenue surprises) on stock returns is lower (higher) in R&D intensive companies. Also, market reaction to earnings surprises is lower in the fourth quarter, and to revenue surprises it is higher in industries with oligopolistic competition. A comprehensive analysis indicates that, in contrast to previous studies for the full sample, in several contexts market reaction to earnings surprises is not higher than to revenue surprises.     

上市公司信息披露质量与证券分析师盈利预测

本文研究了上市公司信息披露状况与分析师预测行为之间的关系，结果发现，分析师的预测准确性总体上显著优于随机游走模型。进一步的研究发现，上市公司信息披露状况会对证券分析师的预测特征产生影响，信息披露透明度越高，分析师预测对会计盈利数据的依赖程度越低，预测准确性也随之提高。     

Use of Fuller's Technique to Reduce Measurement Error in the Returns/Earnings Association

Empirical estimates of the earnings response coefficient have consistently been lower than theory predicts. This may be because empirical proxies for unexpected earnings contain measurement error. I demonstrate and evaluate the use of a recently developed technique by Fuller that yields consistent parameter estimates in the presence of measurement error. The empirical results indicate that this technique is successful at mitigating measurement error bias in the earnings response coefficient. The earnings response coefficient increases by as much as 52%. In contrast, replication of the techniques performed in previous studies increases the earnings response coefficient by only 8%.     

Private Equity Involvement and Earnings Quality

Abstract:  This paper examines the relation between private equity (PE) investors' involvement and their portfolio firms' earnings quality. We operationalize earnings quality through comparative analyses of conditional loss recognition timeliness. For a sample of unlisted Belgian firms, we find that PE involvement increases a firm's willingness to recognize losses more timely as compared to industry, size and life-cycle matched non-PE backed firms. Further, we document more powerful earnings quality effects for firms backed by independent and captive PE-investors as compared to firms backed by government-related PE-investors. Finally, we find no systematic variation in earnings quality across different levels of PE ownership. Our results are robust to the inclusion of various controls and remain unaffected when we consider the endogeneity of PE investments and compare pre- and post PE investment years. The current results provide novel evidence towards the understanding of PE investors' governance implications for portfolio firms' earnings quality.     

Earnings Persistence, Losses and the Estimation of Earnings Response Coefficients

One of the major themes of capital markets accounting research concerns mapping the relation between accounting earnings and security returns. There is still not agreement on the functional form of this relation. The models analysed here are those where: the level of earnings alone, the change in earnings alone, or both, scaled by price, are used as explanatory variables for returns. This article demonstrates that if earnings are either completely permanent or entirely transitory, the earnings response coefficients (ERCs) estimated by levels and changes models should coincide. However, if earnings comprise a mixed process of permanent and transitory components, the ERC estimated by the levels will differ from that estimated by the changes model. Using losses to identify transitory components in earnings, empirical evidence consistent with these predictions is provided.
A combined model using both the level of, and change in, earnings is justified as a weighted average of an earnings and a book value valuation model (e.g., Ohlson, 1989). An alternative rationalization concerns the mitigation of an errors-in-variables problem associated with the estimation of unexpected earnings (Ali and Zarowin, 1992). The results for the combined model are more consistent with the latter. In this context, some previous empirical studies perceive the levels variable as a useful addition to the changes variable when there are transitory components in earnings. However, the evidence reported here suggests that the level of earnings, scaled by price, appears to be the fundamental earnings explanatory variable for returns (Ohlson, 1991, p. 1). The changes variable can, when the errors-in-variables problem is not mitigated by other methods, be a useful addition to the levels variable.
