We suggest that the failure of investors to distinguish between an earnings component's autocorrelation coefficient (unconditional persistence) and the marginal contribution of that component's persistence to the persistence of earnings (conditional persistence) provides a partial explanation of post‐earnings‐announcement drift, post‐revenue‐announcement drift, and the accrual anomaly. When the conditional persistence of revenue surprises is high (low) relative to its unconditional persistence, both the post‐earnings‐announcement drift and the post‐revenue‐announcement drift are high (low), because investors’ under‐reaction to revenues and earnings is stronger when the persistence of revenue surprises is more strongly associated with the persistence of earnings surprises. Also, the mispricing of accruals decreases substantially when the conditional persistence of accruals is high relative to its unconditional persistence, because investors’ over‐reaction to accruals is mitigated when the persistence of accruals is indeed more strongly associated with the persistence of earnings. Our findings also suggest that financial analysts’ failure to distinguish between unconditional and conditional persistence of revenues and accruals results in more biased revenue and earnings predictions.  相似文献

This study examines how accrual manipulations affect firm valuation in the years surrounding the passage of the Sarbanes‐Oxley Act (SOX). We compare the absolute percentage pricing errors of RIM and DCF valuation models for a group of US firms suspected to have engaged in accrual manipulations to avoid a small loss or a small earnings decline vs. ‘Normal’ firms matched on industry, year and size. We find that RIM can better estimate intrinsic value than DCF for the matched Normal firms in the pre‐SOX period, but not so for accrual manipulators, and that SOX mitigates the harmful effect of accrual manipulations, completely eliminating the difference in RIM's accuracy advantage over DCF between Normal firms and accrual manipulators. As a further analysis, we redefine Suspect firms as real‐activity manipulators and find a significant across‐group difference in accuracy wedge in both sample periods, implying that SOX has prompted firms to favor real‐activity manipulations over accrual manipulations.  相似文献

This paper analyses the effects of dynamic correlations between stock and bond returns issued by the same firm on the speed of adjustment towards target leverage. The results show that the estimated correlations are time varying, show persistence and differ among firms. Analysis of the potential explanatory variables reveals that the correlations decrease with negative expectations about future aggregate risks, but only for firms with a low default probability. In contrast, correlations are positively associated with specific risk measures, especially idiosyncratic stock risk and financial leverage. The positive relationship between the correlations and the leverage ratio suggests that target leverage can be achieved faster when the stock–bond correlation is high. Our results show that this is the case.  相似文献

The extant literature shows that institutional investors engage in corporate governance to enhance a firm's long‐term value. Measuring firm performance using the F‐Score, we examine the persistent monitoring role of institutional investors and identify the financial aspects of a firm that institutional monitoring improves. We find strong evidence that long‐term institutions with large shareholdings consistently improve a firm's F‐Score and that such activity occurs primarily through the enhancement of the firm's operating efficiency. Other institutions reduce a firm's F‐Score. Moreover, we find evidence that, while monitoring institutions improve a firm's financial health, transient (followed by non‐transient) institutions trade on this information.  相似文献

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.  相似文献

We adapt the dissonance‐minimising (DM) format proposed by Blamey et al. [Land Economics, 75 (1999) 126] in a dichotomous choice contingent valuation survey to estimate the economic benefits of preserving a cultural heritage site in Vietnam. We find that the DM format can be successfully applied to avoid biases because of yea‐saying in a developing country context.  相似文献

Although previous research suggests that people prefer to think of themselves as being authentic (or individualistic) travellers rather than stereotyped tourists, there have been few studies investigating the external validity of such claim. This paper addresses this research gap by investigating tendencies to dissociate the self from typical tourists in terms of travel motivation. Findings suggest that people perceive their own travel motives to be different from those who they perceive as typical tourists and that these tendencies generalize across people involved in different forms of tourism. This paper discusses the results from a social psychological perspective and provides implications for future research and destination management alike. © 2014 The Authors.

在预期利率水平走高和货币政策转向稳健的背景下,湖北某些地方融资平台还本付息压力陡增,必须谨防资金链断裂,从而避免资金危机和风险的倒逼。地方投融资平台的清理重构的基础条件是建立清晰的地方资产负债表和多样性的融资模式,但最终取决于地方政府自觉放弃在过多领域的投资主导,唯如此,才能在属于自己的领域规范地完成融资任务。  相似文献

以2003—2009年间的1757个公司年度为样本,考察企业资本结构对供应商融资(应付账款和预付账款)的影响。研究发现:企业的资本结构(财务杠杆)对应付账款比例具有显著的负向效应;企业的资本结构(财务杠杆)对预付账款比例具有显著的正向效应;投资者保护程度较强的企业(国有控股企业和大规模企业)能够获得更多的供应商融资。  相似文献
