农民工养老保险参与决策：一个OLG模型的考察

通过构建一个农民工追求跨期效用最大化的OLG模型,理论分析了均衡条件下农民工收入及风险偏好因素对其养老保险参与决策的影响;基于全国31个省市的调查数据,利用双变量Probit模型实证分析了个人与家庭特征、收入与土地、务工状况与预期等因素对农民工养老保险参与决策的影响。结果表明：务工与务农收入对农民工参与养老保险决策的影响并不显著,而恩格尔系数和非收入性因素却大多显著地影响了农民工的参保决策。为此,一方面,要提高农民工的收入水平、生活宽裕程度和支付能力,使之更有意愿和能力参与养老保险;另一方面,要增强农民工对未来生活确定性的预期和安全感,使之参与养老保险的水平得以提高。     

“社会养老”是否淡化了“子女责任”观念？--来自中国农村居民的经验证据

参保行为与养老观念存在双向因果关系，倾向于子女养老的居民参加养老保险的概率较低，而参加养老保险也改变着居民的养老观念。通过联立方程模型以及工具变量控制内生性后，得出了养老保险淡化“子女养老”观念的净效应，进而指出养老保险制度不仅挤出了子女对老人的经济支持，同时也弱化了人们的家庭养老观念。国家大力推行的养老保障体系在行为与观念两个层面上挤出了家庭养老，以国家制度化养老保障体系为主体的社会养老模式对家庭养老模式具有替代性。在养老模式的变迁中要综合考虑各主体的功能与责任，联合各界力量共同承担社会养老责任。     

The gender gap in pensions in Latin America

Lower female lifetime labour market participation rates, greater interruptions during their working lives, and wage gaps contribute to create gender gaps in pensions at the time of retirement. The design of social security systems may reinforce or attenuate these gaps. This article provides new evidence on gender gaps in access to pensions and in pension income in four Southern Cone countries in Latin America and analyses their evolution between 2000 and 2013, showing significant improvements in both gaps, with differential patterns by countries. The decrease in the gender gap in pension income has been particularly significant in Argentina and Brazil. In both cases, the largest increases in pension values during the period correspond to the lowest income percentiles, where women are overrepresented. The application of redistributive policies in these countries, aimed at reducing poverty and inequality but not necessarily focused on gender equity, has had positive and probably unintended consequences in terms of reduction in gender gaps in pensions.     

Pension policy in China, Singapore, and South Korea: An assessment of the potential value of the notional defined contribution model

The rate of population aging is increasing in the developing world and the trend is particularly dramatic in East Asia. One consequence is sharp increases in old-age dependency ratios which have major implications for the sustainability of current public pension schemes. These trends are pushing pension policy experts in many of these countries to search for new pension models that are more suited to the increased demographic pressures they will be facing in the decades ahead. In this article we discuss five alternative public pension models with a focus on the newest of these models, the notional defined contribution (NDC) approach. We consider three countries with very different pension systems in place, two from East Asia (China and South Korea) and one from South East Asia (Singapore). The central question we address is which (if any) of the limitations in these existing models might more adequately be addressed using a variant of the NDC model. We conclude that the NDC model has the most to offer China and the least to offer Singapore.

Extending social security coverage to the rural sector in China

In late 2009 China launched an innovative, voluntary programme that by 2011 had extended pension coverage to 326.4 million people in the rural sector, including contributors and beneficiaries. It requires one contribution per year and provides a flat‐rate benefit and a contributions‐related benefit through a contributory individual account, with a government guarantee that the benefit will continue for life. The programme encourages participation of persons who do not pay income taxes, and thus have no tax incentive to participate, by providing substantial government subsidies. As a further incentive, old‐age benefits are provided to older parents when all their adult children participate in the contributory programme.     

夏敬观词学贡献论略

夏敬观是晚近词坛著名的词学活动家，其词学活动及词学著述对晚近词坛影响甚大。夏氏词学理论及时总结了他和当时同仁词创作的经验，又是晚近词坛继承王鹏运、朱祖谋等人应用小学方法研究词学整理词籍开创词学研究新格局的重要创获。夏氏词论不仅深化了清代以来对词格律韵调的研究，而且深化了对唐五代北宋词的研究，还总结和深化了历代关于“词”“学”关系命题的思考和探讨，在词学史上具有重要的意义。     

高校学报研究生来稿学术不端现象管窥

对高校学报研究生来稿中的学术不端现象进行了梳理和分析，认为应从加强学术道德教育、充分发挥导师的作用、增强著作权法意识、改革研究生考核评价制度以及缩短审稿周期、及时向作者反馈审稿信息等方面，来防范和遏制学术不端现象。     

农村养老制度对家庭人力资本积累影响研究述评

自新增长理论形成以来，将养老保障制度与人力资本积累相联系进行研究成为社会保障、社会学等领域的研究热点之一。无论是国外的理论研究还是实证研究均表明，养老保障制度对于人力资本积累的影响作用是十分明显的。但我国目前理论界直接对养老保障制度与人力资本积累之间关系展开研究的尚属少数。因此，关于养老保障制度对家庭人力资本积累的影响研究的广度和深度均有待发掘。     

《考工记》对科技档案的贡献之研究

《考工记》是两千多年前由齐国人编纂的一部手工业科技文献，也是目前中国所见年代最早的有关手工业制造及工艺技术的记述。早在1996年，在齐文化发源地山东淄博召开的“第一届中国科技典籍国际会议”上，学者们就此书的科学价值发表了多篇论文，形成了《考工记》研究的一个高潮。重温这部我国手工业制造编纂史的奠基之作，对指导科技档案工作仍有重要的现实意义。
