人口老龄化进程中养老保障的消费增进效应——基于CHARLS数据的研究

利用2013年中国健康与养老追踪调查(CHARLS)数据中的8355个家庭数据,在控制家庭人口特征和家庭经济能力的情况下,分别从家庭消费水平和家庭消费结构两方面考察人口老龄化进程中养老保障对家庭消费的影响。结果显示:养老负担会使家庭人均消费支出明显下降,但是医疗保健方面的消费支出占比会显著提高;参加养老保障会显著提高家庭的人均消费支出,尤其是无养老负担家庭会减少对未来养老的预防性储蓄而增加当期消费,养老保障的消费增进效应明显,但是有养老保障家庭的各项消费支出占比则没有显著的提高或下降。这充分说明养老负担是家庭消费水平难以提高的重要因素,而养老保障是刺激人口老龄化进程中消费增长的有力手段。     

Age dependency and labour productivity divergence

This study finds strong empirical evidence in favour of the hypothesis that the age composition of population matters for labour productivity growth. We applied the fixed effects panel model using data on a large number of countries over the period 1980–2010. Our results suggest that higher age dependency not only directly impacts negatively on labour productivity but also modifies the impact of other determinants of labour productivity. Child dependency has a more adverse effect on labour productivity than old age dependency. We specifically find that the marginal effects of gross capital formation, information and communication improvement, and labour market reforms are significant at lower levels of age dependency. However, the marginal effect of savings on labour productivity is high at a high level of age dependency. The impact of age dependency varies between developed and developing economies. Diversity in the size and nature of age dependency across regions and different income groups help to explain the labour productivity differential across them.     

Are new states more corrupt? Expert opinions versus firms’ experiences

We find that new states are perceived to be more corrupt even though businesses do not report more bribery in newer states. This is suggestive of an unearned, and likely high, reputational cost to being a new state. These findings hold over a number of specifications that include additional economic, historical and geographic controls.     

新型农村养老保障制度改革——北京模式的探索意义及其适用条件

本文以北京模式为案例,探讨了新型农村养老保障体制改革的主要特征和改革方向。北京模式明确提出政府提供基本养老保障的职责,推动建立人人共有的基本养老保障制度,使其具有研究价值和经验借鉴意义。当然,北京市的社会经济发展水平和财政能力,使其推广上应注意适用条件,特别是针对人口老龄化水平高的中西部劳动力输出大省,以及财政能力薄弱的省份,单纯依靠地方财政将面临巨大的财政压力。在分税制的情况下,需要在制定合理的财政补贴标准基础上,科学地划分中央财政和地方财政的支持比例,才能确保财政的可持续性,建立全国统一的新型农村养老保障体系。

Young consumers in the digital era: The selfie effect

This article investigates a mechanism named the selfie effect. By their frequent sharing of selfies on social media, perhaps displaying their cool new fashions or newly acquired tattoos, young people—unintentionally—help providers to promote their products and services, and thereby contribute to the commercial pressure. The existence of a selfie effect builds on hypotheses originating from a pilot interview study concerning how young adults master the consumer role. In this article, the existence of a selfie effect is investigated in a nationally representative web survey with 1,707 respondents aged 16–60, living in Norway. While 59% of the teenagers said they were posting selfies weekly or more often, only 2% among those in their fifties did. The multivariate quantitative analyses support the idea that teenagers and young adults, frequently online, become vulnerable in the consumer role. Particularly posting selfies and following bloggers increase consumer detriment and overconsumption.     

Gender difference in the impact of retirement on cognitive abilities: Evidence from urban China

This paper examines the impact of retirement on cognitive functioning by gender in urban China and investigates the underlying mechanisms. Based on data from the China Health and Retirement Longitudinal Study, the paper uses the mandatory retirement ages and different policy enforcement between the public and private sectors as instruments for retirement status. The analysis finds substantial gender heterogeneity in the effect of retirement on cognition, with a positive and significant effect for males, but a negative and less significant effect for females. The beneficial effects on cognition are stronger for male blue-collar workers, who are likely to pursue a more active lifestyle at retirement. Further investigation shows that the results are partly driven by differential behavioral changes at retirement, and the gender difference in retirement ages may also play a potential role.

Does Age Exacerbate the Gender-Wage Gap? New Method and Evidence From Germany, 1984–2014

ABSTRACT

Given theoretical premises, the gender-wage gap adjusted for individual characteristics is likely to vary according to age. This study adapts John DiNardo, Nicole M. Fortin, and Thomas Lemieux's (1996) semi-parametric technique to disentangle year, cohort, and age effects in adjusted gender-wage gaps. The study relies on a long panel of data from the German Socio-Economic Panel (SOEP) covering 1984–2015. The results indicate that, in Germany, the gender-wage gap increases over a birth cohort's lifetime, including in the post-reproductive age for some birth cohorts. The results suggest that age and gender are overlapping handicaps in the labor market and call for a policy intervention.     

基本养老保险制度下女性养老金水平研究——兼析养老金性别差异

基本养老保险制度运行10多年来,在提供退休保障方面发挥了重要的积极作用。但女性养老金问题值得高度重视。其中,女性退休年龄是影响养老金水平的重要因素,还带来了养老金性别差异。女性退休年龄已经与政策目标以及预期寿命不符,对既不利于保障退休生活,也不利于制度的健康持续发展。从国际比较看,我国女性退休年龄低于国际及亚太地区平均水平,而养老金替代率的性别差异也明显大于国际水平。因此,应在统筹考虑我国养老金体系建设的前提下,抓紧研究论证提高退休年龄,特别是先行逐步提高女性退休年龄的方式方法。
