Female Labor Supply,Human Capital,and Welfare Reform

We estimate a dynamic model of employment, human capital accumulation—including education, and savings for women in the United Kingdom, exploiting tax and benefit reforms, and use it to analyze the effects of welfare policy. We find substantial elasticities for labor supply and particularly for lone mothers. Returns to experience, which are important in determining the longer‐term effects of policy, increase with education, but experience mainly accumulates when in full‐time employment. Tax credits are welfare improving in the U.K., increase lone‐mother labor supply and marginally reduce educational attainment, but the employment effects do not extend beyond the period of eligibility. Marginal increases in tax credits improve welfare more than equally costly increases in income support or tax cuts.     

Supply Chain Consequences of Subsidies for Corporate Social Responsibility

The use of government incentives tied to market prices as means of boosting corporate social responsibility (CSR) has expanded notably in recent decades. Enhanced business tax deductions for charitable donations and credits for conservation easements are notable cases. While providing incentives for socially desirable behavior to achieve legislative goals has intuitive appeal, the broader economic consequences are not always fully understood. In this study, we examine such wider consequences for supply chains when subsidies for CSR are offered. One effect we identify is that since incentives are typically tied to market value, firms have not only an added incentive to achieve societal objectives (say by donating inventory) but also an incentive to raise output (retail) market prices. A second consequence is that since firms forgo potential revenues by engaging in socially desired behavior, they become increasingly sensitive to supplier pricing; in an uncoordinated supply chain this leads to input (wholesale) price concessions. Among other things, the results underscore that incentives put in place to meet broader societal objectives also have notable ramifications for suppliers, retailers, and consumers in primary markets.

食管癌患者健康相关生命质量研究

目的:探讨食管癌患者的健康相关生命质量现状及影响因素?方法:采用一般资料问卷?欧洲五维度健康评定量表(EQ-5D量表),对209例食管癌患者进行问卷调查,采用单因素分析和多因素分析探讨食管癌患者健康相关生命质量的影响因素? 结果:食管癌患者行动?自我照顾?日常活动?疼痛/不适?焦虑/抑郁五个维度存在问题的比例分别为18.2%?12.0%?22.0%?38.3%?25.4%;自评健康得分(VAS评分)为(75.20 ± 11.00)分;综合健康指数得分(Index得分)为(0.84 ± 0.22)分?患者的性别?家庭年收入?文化程度是VAS评分的主要影响因素;患者的年龄?治疗方式?肿瘤分期?医保类型是Index得分的主要影响因素?结论:实施心理干预?早诊早治?大病医疗保险有助于提高食管癌患者健康相关生命质量?     

女性董事对企业社会责任履行的影响——以慈善捐赠为例

以2002-2014年中国A股非金融类上市公司为研究样本,利用社会角色理论分析了女性董事影响慈善捐赠的作用机理,相对于男性董事,女性董事的“公共型”特征使得她们天生就有同情心,乐于助人和关怀他人,此外还因受性别刻板印象的影响,使得女性董事更加关注慈善捐赠,也愿意积极参与上市公司的慈善捐赠决策.考虑到中国上市公司聘请女性董事可能存在自选择偏误问题,本文采用Heckman两阶段模型有效控制了自选择偏误产生的内生性问题.研究结果表明,董事会中有女性董事的上市公司的慈善捐赠多于没有女性董事的上市公司.文章的研究在一定程度上解释了女性董事为什么会影响上市公司的慈善捐赠,揭示了女性董事在董事会所扮演的角色,对上市公司聘请女性董事和积极履行社会责任都具有重要的参考价值.     

股权结构、产权性质与高管薪酬粘性——基于我国A股上市公司的实证研究

近年来,我国上市公司高管薪酬尤其是国有企业高管薪酬成为政府监管的重点和社会舆论关注的焦点问题.文章以2010-2014年我国沪深两市A股上市公司为研究对象,实证检验了上市公司高管薪酬粘性的存在性;同时,重点考察了股权结构、产权性质对上市公司高管薪酬粘性的影响程度.实证结果显示:我国上市公司高管薪酬具有显著的粘性特征;在股权结构的影响方面,第一大股东持股比例越高,股权制衡度越低,高管薪酬粘性相应越高,当控股股东与中小股东之间产生利益冲突时,上市公司高管作为控股股东利益的代表,通常忽视上市公司高管薪酬与企业业绩的不对称性,因此薪酬粘性成为控股股东对高管的奖励;在产权性质的影响方面,国有企业高管薪酬粘性显著大于非国有企业.研究结论对于提高我国上市公司的治理效率、降低代理成本、优化激励机制设计具有一定的启示.     

公司治理对会计信息披露质量影响 ——基于我国生物医药业上市公司的实证研究

会计信息披露是企业向信息使用者揭示和反映企业价值运动,高质量的信息披露可以降低信息不对称程度,使投资者能更正确地做出判断.以生物医药业上市公司为例,采用Logistic回归分析方法,系统研究公司治理与会计信息的披露质量之间的关系,发现公司治理中的董事会规模、独立董事比例和监事会规模的提高会使得会计信息披露质量得到提高,董事会会议次数与会计信息披露质量显著负相关.     

中国制造业产业生命周期研究———基于１９９３—２０１４年数据的分析

中国制造业面临着日益严峻的资源和环境约束,制造业产业如何在转型升级、创新驱动中合理定位和选择发展道路尤为重要。通过中国制造业产业生命周期分析,明确制造业产业发展阶段,可以有效制定相关政策予以促进或抑制。因此,运用产出增长率法、产业生长曲线法、综合指标分析法等方法,基于１９９３—２０１４年的制造业产业数据展开实证检验。结果发现,基于３种不同方法所得结论基本一致：１／３的制造业产业仍然处于快速成长阶段,但半数制造业产业已经处于成熟期,少数则处于衰退期。针对处于不同生命周期阶段的产业,可分别采取创新发展、转移产能等策略。     

贫困地区新生代女性农民工休闲生活现状调查研究--以甘肃省定西市为例

休闲已成为现代人生活、工作所不可或缺的组成部分。作为经济转型时期的特殊社会群体,新生代女性农民工的休闲生活现状值得关注。研究以甘肃省定西市为例,从休闲时间、休闲消费、休闲认知三个维度对本地区新生代女性农民工与男性农民工、同龄城市女青年休闲生活进行对比研究,得出结论:贫困地区新生代女性农民工休闲时间严重不足,主要休闲消费方式仍处于消极型的休闲层次类型;相对于上一代农民工而言,她们已经认识到休闲的重要性,但由于受封闭的休闲空间及拮据的经济条件所限,她们的休闲动机仍停留在马斯洛的五个需求层次中前两层的初级需要。针对此现状,文章提出了相应的对策与建议。      

Empirical likelihood based detection procedure for change point in mean residual life functions under random censorship

The mean residual life (MRL) function is one of the basic parameters of interest in survival analysis that describes the expected remaining time of an individual after a certain age. The study of changes in the MRL function is practical and interesting because it may help us to identify some factors such as age and gender that may influence the remaining lifetimes of patients after receiving a certain surgery. In this paper, we propose a detection procedure based on the empirical likelihood for the changes in MRL functions with right censored data. Two real examples are also given: Veterans' administration lung cancer study and Stanford heart transplant to illustrate the detecting procedure. Copyright © 2016 John Wiley & Sons, Ltd.
