股权激励、反收购条款与企业创新

股权激励和反收购措施是公司内外部治理机制的重要方式.文章以2006—2017年沪深两市上市公司为研究样本,将股权激励、反收购条款和企业创新纳入统一分析框架中,考察两种公司治理机制对企业创新的综合影响.研究发现:股权激励显著提升企业创新产出水平,但反收购条款负向调节股权激励对企业创新的促进作用,控制内生性后结论依然成立.进一步分情景分样本进行分析发现,股权激励的创新效果相对稳定,但反收购条款的负向调节作用明显受外界环境和条件的影响,主要体现在市场竞争程度低、股权分散程度低及高管风险偏好程度低的企业中.本文的研究结论对理解股权激励的实施效果及反收购条款的公司治理作用具有一定的参考意义.     

机动车辆保险承保周期的回归模型分析

通过构造一个包含多个变量的回归模型来检验各种因素对保费变动的影响,结果表明:滞后损失率和滞后保费增长率对当期保费增长影响非常显著;滞后损失增长率对当期保费增长率影响不显著;在我国机动车辆保险中,宏观经济因素包括利率和GDP对保费增长率的影响很小.因此,我国机动车辆保险承保周期存在原因较为符合承保能力限制假说.     

Cue usage in financial statement fraud risk assessments: effects of technical knowledge and decision aid use

This paper investigates the effects of technical knowledge and decision aid use on financial statement fraud risk assessments made by directors and students. More extreme fraud risk assessments are made when participants identify and process larger (smaller) numbers of diagnostic (non‐diagnostic) factors, with technical knowledge driving diagnostic factor identification. Significant decision aid‐technical knowledge effects are also found; decision aid use has a detrimental effect on high‐knowledge directors while improving performance in inexperienced, low‐knowledge students. These results suggest that although decision aids can afford gains in performance in inexperienced users, they can have unintended and/or paradoxical behavioural effects on experienced users.     

试论人格权的本质

在我国民法典制定过程中,人格权的立法体例是一个有争议的问题。人格权采取何种立法体例,关键在于如何对待人格权即人格权的本质问题。本文认为人格权是一种自然权利,是内在于人格的;人格权不仅是宪法上的权利,同时也是民事权利;人格权的本质属性不是支配权。     

Reversing an impairment loss and earnings management: The role of corporate governance

This paper examines whether the reversal of a previously recognized impairment loss provides an opportunity for earnings management, and whether such behavior is associated with managers' incentives. It also examines whether a corporate-governance mechanism can mitigate this behavior. Since 2005, listed companies in Taiwan have been required to comply with accounting standards, equivalent to International Accounting Standards (IAS) No. 36 “Impairment of Assets,” which allow reversals of asset-impairment losses. Data on a sample of 55 firms that reversed impairment losses between 2005 and the first quarter of 2007 were matched by industry and size with 55 control firms. Empirical results show that firms recognizing more impairment losses are more likely to reverse impairment losses when doing so would avoid an earnings decline in a subsequent period, which is consistent with the “cookie jar” reserve hypothesis. We also show that such behavior is more pronounced for firms with higher debt ratios, consistent with earnings management being associated with the incentive to avoid violation of debt covenants. However, an effective corporate governance mechanism could mitigate such behavior. Our study may contribute to the debate on global convergence with IFRS, especially convergence between IFRS and U.S. GAAP with respect to the “Impairment of Assets,” by providing a rationale for the latter's prohibition of reversals. It may also contribute to the corporate-governance literature by showing the effect of governance mechanisms on deterring earnings management.

The impact of accounting information quality on the mispricing of accruals: The case of FRS3 in the UK

We exploit a unique setting of accounting regulation change to examine how accounting information quality affects the well-documented accrual anomaly. We show a significant reduction in the negative return predictability of accruals among UK companies with poorer accounting information quality following the introduction of Financial Reporting Standard No. 3: Reporting Financial Performance (FRS3). While the functional fixation hypothesis attributes the mispricing of accruals to the judgemental error of end-users of information, our findings suggest that the supply side of information also plays a crucial role. Our results provide evidence that regulatory interventions seeking to improve accounting information quality can reduce the mispricing of securities in the capital market.     

Marketing Period Risk in a Portfolio Context: Comment and Extension

This paper re-examines and extends the findings of Bond et al., Journal of Real Estate Finance and Economics, 34, 447–461, (2007) who consider the theoretical model of Lin and Vandell, Real Estate Economics, 35, 291–330, (2007) to determine the extent to which individual real estate asset return characteristics caused by marketing period risk disappear in a large, diversified real estate portfolio. The effects of marketing period risk are found to disappear in the limit with growth in the size of the portfolio, with ex ante variance approaching ex post variance, but only if the portfolio consists of nonsystematic risk alone, in which case both approach zero. The marketing period risk factor (MPRF), representing the ratio of ex ante to ex post variance, however, does not in general approach zero in the limit, in fact could increase or decrease depending upon the illiquidity characteristics of the individual assets and the magnitude and degree of correlation among individual property returns and marketing periods. The results suggest that even large institutional real estate portfolio managers must consider the illiquidity present in their portfolios and cannot assume that its effect will be diversified away.
