Individual Large Shareholders,Earnings Management,and Capital‐Market Consequences

Using a large hand‐collected sample of all blockholders (ownership ≥ 5%) of S&P 1500 firms for the years 2002–2009, we first document significant individual blockholder effects on earnings management (accrual‐based earnings management, real earnings management, and restatements). This association is driven primarily by these large shareholders influencing rather than selecting firms’ financial reporting practices. Second, the market's reaction to earnings announcements suggests that investors recognize the heterogeneity in blockholders’ influence on earnings management. The results highlight the highly individualized effects of blockholders and a mechanism through which shareholders impact reported earnings.     

Too Good to be True? An Analysis of the Options Market's Reactions to Earnings Releases

Using option implied risk neutral return distributions before and after earnings announcements, we study the option market's reaction to extreme events over earnings announcements. While earnings announcements generally reduce short‐term uncertainty about the stock price, very good news does not reduce uncertainty and slightly bad news actually increases uncertainty. We also find that left tail probabilities decrease over earnings releases while right tail probabilities increase. We interpret these findings as evidence of maintained investor expectations that very good news is generally not released during earnings announcements, combined with skepticism in the form of lingering uncertainty at the release of such very good news.     

Myopic market pricing and managerial myopia

This paper develops a firm‐level measure of myopic market pricing, which captures the extent to which the market overvalues short‐term expected abnormal earnings relative to longer‐term ones. The empirical analysis shows that myopically priced firms manage earnings more actively and invest less in R&D. The impact of myopic market pricing is concentrated in firms where managers cater more to market pricing, that is, in firms with greater short‐term investor ownership, with CEO compensation that is more sensitive to the firm share price, and with higher equity dependence. Additional tests show that these findings are robust to the consideration of market (under)overpricing. The results suggest that when managers cater to market pricing, market myopia encourages managerial myopia.     

Revisiting the labor supply effect of social security earnings test: New evidence from its elimination and reinstatement in Japan

We explore the labor supply effect of the social security earnings test in Japan on those aged 65–69 years through a combined examination of the elimination of the earnings test in 1985 and its reinstatement in 2002. We present evidence showing that the effects of changes in the earnings tests on the labor supply of the elderly are not symmetric, controlling for changes in the attributes of workers and firms. The repeal of the earnings test in 1985 did affect the earnings distribution of the elderly (especially for male), while its reinstatement in 2002 did not alter the earnings distribution.     

黑龙江省上市公司盈余管理研究

以黑龙江省23家A股上市公司共138个子公司为样本,选取2006-2011年的数据对应急盈余管理和真实盈余管理所进行的分析结果表明,黑龙江省上市公司普遍存在,各公司真实盈余管理水平相差较大;有一半以上的公司倾向于采取应计盈余管理进行正向操控,而采用真实营盈余管理进行负向操控;应计盈余管理和真实盈余管理的变化总体呈相反趋势;各行业、地区的盈余管理相差较大。在今后的研究中,应加强对公司盈余管理的遏制,从而促进黑龙江省经济的健康发展。     

高管连锁网络与股价同步性

本文以2009—2018年中国A股上市公司为研究样本,考察了高管连锁网络对公司股价同步性的影响。研究发现：高管连锁网络会提高公司的股价同步性,处于高管连锁网络越中心位置的上市公司,其股价同步性越高;从趋同性和信息透明度两个方面进一步分析高管连锁网络对股价同步性的作用机制,发现高管连锁网络并非通过降低公司透明度这一途径对股价同步性产生影响,而是因为连锁高管加强了上市公司间的行为学习、信息和资源的共享,促使公司间基础特征趋同,进而提高了公司的股价同步性;根据联结类型的不同将高管连锁网络划分为董事网络、监事网络和高管网络,实证结果表明高管网络对股价同步性的提升效应最大,董事网络次之,监事网络对股价同步性无显著影响;区分产权性质和法治环境后发现,在国有企业和所处法治环境较差的企业中,高管连锁网络提高股价同步性的效应更显著。研究结论为提升资本市场信息效率提供了理论支撑。     

中国医药上市企业公司治理结构与企业绩效关系的实证研究

选择了2007—2009年中国A股医药上市企业为研究样本,对中国医药上市企业公司治理结构与企业绩效的关系进行了实证研究。研究结果表明,中国医药企业公司治理结构与企业绩效之间存在着密切的关系,但同时也发现医药上市企业的董事会和监事会对提升企业绩效并没有充分发挥其应有的监督作用,管理层的激励机制也有待进一步改善。     

意识形态对企业家人力资本的影响路径——以广东温氏食品集团为例

意识形态是社会存在反映,也是一种重要的非正式制度。在回顾意识形态与企业家关系的相关理论的基础上,分析意识形态对企业家人力资本的影响路径。研究认为,意识形态对企业家人力资本的影响也由此可依次分为三个阶段：企业家对意识形态感知的认识阶段;企业家理性判断是否将共有意识形态纳入已有认知结构的评价阶段;共有的意识形态转化为个性化意识形态的实现阶段。论文结合广东温氏集团案例,揭示意识形态影响企业家人力资本的阶段性路径特征,提出针对意识形态对企业家人力资本影响的阶段性特点的阶段性战略,认识阶段增强企业家角色偏好,评价阶段降低企业家对意识形态判断的交易成本,实现阶段打造企业家声誉等,以期从而促进企业家人力资本提升。     

上市公司盈余管理动机的研究分析

近年来,上市公司管理层通过盈余管理粉饰公司业绩,误导投资者决策的行为受到社会广泛的关注。通过对盈余管理动机的深层研究。对于上市公司盈余管理行为的监管与控制应该双管齐下。既要通过完善相关会计法规减少上市公司盈余管理可以选择的手段,又要完善中国上市公司的公司治理结构,增强对少数股东的利益保护机静】,从根本上抑制上市公司盈余管理的动机,使得公司的财务报告反映公司的真实业绩,促进中国资本市场的繁荣发展。
