农村信用社产权制度改革:理论、绩效与出路

农村信用社产权制度改革不仅是一个金融问题,而且是一个复杂的社会问题.长期以来我国农村信用社按照合作制进行规范绩效差的主要原因是,农村信用社产权制度改革的国家偏好和农民的接受程度之间存在着巨大的矛盾.文章建议通过稳定农村信用社的经营、拉长农村信用社产权制度改革的周期、完善农村信用社产权制度改革的外部环境、增加农村信用社产权制度改革的途径等四个方面的措施来推动我国农村信用社的产权制度改革.

The relationship between stock returns and volatility in international stock markets

This study examines the relationship between expected stock returns and volatility in the 12 largest international stock markets during January 1980 to December 2001. Consistent with most previous studies, we find a positive but insignificant relationship during the sample period for the majority of the markets based on parametric EGARCH-M models. However, using a flexible semiparametric specification of conditional variance, we find evidence of a significant negative relationship between expected returns and volatility in 6 out of the 12 markets. The results lend some support to the recent claim [Bekaert, G., Wu, G., 2000. Asymmetric volatility and risk in equity markets. Review of Financial Studies 13, 1–42; Whitelaw, R., 2000. Stock market risk and return: an empirical equilibrium approach. Review of Financial Studies 13, 521–547] that stock market returns are negatively correlated with stock market volatility.     

Late for a very important date: financial reporting and audit implications of late 10-K filings

Delays in financial reports often reflect issues related to period-end accounting and audit processes. We investigate the impact of filing delays in connection with auditor characteristics on the quality of financial statements in a sample of firms that filed Form 10-K after the statutory due date. We find that late filing firms are associated with lower financial reporting quality compared to timely filing firms matched by propensity scores, where financial reporting quality is measured by the absolute value of performance-matched discretionary accruals and the probability of a late filing being restated in subsequent periods. Furthermore, we demonstrate that the adverse consequences of late filings can be largely mitigated by having a Big 4 auditor. The differential audit quality stems primarily from Big 4 auditors in large offices and is more pronounced when an auditor may need to draw on additional resources in a limited period.

创业激情:情绪视角的创业研究综述

认知角度的创业研究已相当成熟,而情绪视角的研究才刚刚起步,创业激情在创业中的作用备受关注。综述了创业激情的内涵、测量、影响结果、作用机制以及创业激情的来源,发现现有研究还存在以下问题:内涵模糊、测量工具不完善、影响和作用机制缺乏系统性、来源不明确。在此基础上构建了创业激情研究的整合模型,提出采用案例分析方法对个体、团队、组织层面的创业激情进行界定,从激情本质出发,开发新量表,对创业激情的负面效应给予关注,未来研究可探讨创业激情对创业结果中介机制间的交互作用,并根据不同创业类型对创业激情进行跨文化分析。
