会计盈余及时性对公司治理机制影响的实证研究

本文通过考查1997年到2004年间上市公司治理机制代理变量与会计盈余及时性指标之间截面数据相关关系,探讨治理机制是否随会计盈余及时性而变化。结果基本支持了本文的假设:董事对高成本信息收集和整理的需求与会计系统信息的有用性是倒数关系,外部股东对高成本信息收集和整理的需求与会计系统信息的有用性是正相关关系;会计系统信息有用性的重要决定因素是解释股权价值现时变化的程度;以高成本的监督活动为特点的特殊治理结构是股东和董事对高成本信息收集和整理需求的反应。     

中国宏观经济总量的实时预报与短期预测——基于混频数据预测模型的实证研究

季度GDP的走势与波动不仅会影响政府的财政收支、企业的盈利和财务状况,甚至还会影响家庭和个人的收入与支出,是宏观经济总量预报、预测与分析的重中之重。传统的宏观经济总量预测模型是基于同频数据进行的,高频和超高频数据必需处理为低频数据,这不仅忽略了高频数据信息的变化,还影响了模型预报和预测的及时性,降低了模型的预测精度。本文将混合数据抽样模型(MIDAS)用于中国季度GDP的预报和预测,实证研究表明,出口是造成我国金融危机时期经济增长减速的主要因素,MIDAS模型在中国宏观经济总量的短期预测方面具有精确性的比较优势,在实时预报方面具有显著的可行性和时效性。

Corporate governance and the timeliness of corporate internet reporting by U.K. listed companies

This study is an examination of the timeliness of corporate internet reporting by U.K. companies listed on the London Stock Exchange (LSE). The research examines the significance of several corporate governance and firm-specific characteristics as potential determinants of the timeliness of corporate internet reporting.Our primary analysis provides evidence of a significant association between timely corporate internet reporting and the corporate governance characteristics of board experience and board independence. Our findings provide evidence that boards with less cross directorships, more experience in terms of the average age of directors, and lower length in service for executive directors provide more timely corporate internet reporting. We find that board independence is negatively associated with timely corporate internet reporting.Follow-up analysis provides additional evidence of a significant association between the timeliness of corporate internet reporting and board experience. The evidence indicates that role duality and block ownership are associated with less timely corporate internet reporting.Our findings also reveal strengths and weaknesses in the Internet reporting of U.K. listed companies. Companies need to voluntarily focus on improving the timeliness dimension of their corporate internet reporting so that the EU and U.K. accounting regulators do not replace recommendations with regulations.     

Audit opinion improvement and the timing of disclosure

Companies have been found to report positive information more quickly than they report negative information (i.e., good news early, bad news late). This paper investigates the potential impact of audit opinion change on the timeliness of financial disclosures, with improvements in audit opinion considered to be “good news.” We take both the direction and the magnitude of audit opinion change into consideration, with magnitude measuring how far the opinion is from an unqualified opinion (i.e., an unqualified opinion with explanatory paragraph is closer to an unqualified opinion than a qualified opinion is). We find that firms experiencing an improvement in their audit opinions disclose their financial results earlier, while those with audit opinion deteriorations report their financial results later, and that these effects were related to the magnitude of the opinion change. What's more, there is an asymmetric response to good audit opinion news vs. bad audit opinion news, with bad audit opinion news having a larger effect on earnings timeliness than the effect on earnings timeliness of good audit opinion news. Overall, our results support the “good news early, bad news late” notion. Finally, we also find that overall earnings timeliness has improved in China since the enactment of new reporting regulations in 2006.     

Organizational coordination, development proficiency, and on-time completion of development and international rollout: A contingency analysis of external environments

This study examines the moderating effects of external environmental variables on the relationships between organizational coordination, quality of implementation of new product development (NPD) activities, and on-time completion of (or timeliness in) product development and international new product rollout (INPR) among manufacturing firms in Korea. The results indicate that quality of marketing execution is of greater importance for achieving on-time NPD and multi-country rollout in markets where competitive intensity is high than when it is low. The positive effect of HQ-subsidiary relationships on INPR timeliness is strengthened in rapid rather than slower technology-change environments. By contrast, the positive effect of HQ-subsidiary relationships on INPR timeliness is weakened in high rather than lower competitive-intensity environments. In addition, the beneficial effect of cross-functional integration on NPD timeliness is weakened in markets characterized by a high rate of technological change. The article also discusses the theoretical and managerial implications of the findings.     

The impact of sentiment on price discovery

We study how investor sentiment affects the speed with which prices reflect information. Price discovery is more timely for firms with greater sensitivity to sentiment, as measured by a sentiment beta. Our research improves our understanding of the price formation process when sentiment is not assumed to be constant. Our research design is novel as it considers a sentiment beta as well as economy‐wide sentiment. This provides more comprehensive evidence on the impact of differing types of sentiment on the price formation process.     

The impact of IFRS on accounting quality: Evidence from Greece

This paper examines the impact of IFRS adoption on the quality of accounting information within the Greek accounting setting. Using a sample of 101 firms listed in the Athens Stock Exchange (ASE) for a period of eight years (2001–2008) we find convincing evidence that the implementation of IFRS contributed to less earnings management, more timely loss recognition and greater value relevance of accounting figures, compared to the local accounting standards. Also, our findings document that audit quality further complements the beneficial impact of IFRS since those companies that are audited by Big-5 audit firms exhibit higher levels of accounting quality. Our findings are robust in regard to different model specifications and after controlling for firm-specific effects like size, risk, profitability and growth opportunities.     

信息披露及时性与可靠性关系实证研究

信息披露及时性与可靠性是衡量会计信息披露质量高低的两个重要因素。本文从理论上分析了信息披露及时性与可靠性之间的关系,并对二者的关系进行了实证检验,研究结果发现:我国上市公司信息披露及时性与可靠性之间存在着此消彼长的负相关关系,面对及时性与可靠性的两难选择,我国上市公司优先考虑信息披露的及时性。由于可靠性不被优先重视,导致近年来许多公司急于披露年报,然后频繁地对已披露的年报打补丁。对此,建议证券交易所对打补丁现象做出相应处罚规定,切实提高信息披露的可靠性。同时,会计信息使用者在进行决策时不要只看重信息披露的及时性,还要认识到公司年报中可能隐藏着的不可靠性——年报披露后打补丁。     

The impact of SFAS No. 123(R) on financial statement conservatism

SFAS No. 123(R) requires firms to recognize the fair value of stock options as compensation expense over the vesting period of the options. Thus, SFAS No. 123(R) leads to an overall increase in financial statement conservatism. However, it is not known whether SFAS No. 123(R) increases conditional and/or unconditional conservatism. Because the different forms of conservatism have different implications for the quality of earnings, I investigate which types of conservatism are impacted by SFAS No. 123(R) to gain insight into the ramifications of the Standard. I find that SFAS No. 123(R) leads to an increase in both unconditional and conditional conservatism. I additionally find that the Standard causes an increased negative relation between contemporaneous economic gains and income. These findings hold outside of the sample period and under a non-priced based model of conservatism.
