Retaining and engaging older workers: A solution to worker shortages in the U.S.

Over the next 20 years, many organizations will experience significant shortages of skilled workers. At the same time, because of longer lifespans and a gradual rise in what society has considered the traditional retirement age of 65, older workers will represent a growing proportion of the American workforce. For a variety of reasons, many of these older workers desire to continue working and, if retained and engaged, they constitute a significant labor source for mitigating the emerging shortages of skilled workers. However, many organizations are not prepared to take advantage of this demographic shift; some even generate barriers that impede the retention and engagement of older workers. In this article, we identify a variety of ways in which organizations can retain and engage older workers to meet their staffing needs and enhance organizational performance. We also discuss the relationship of these proposals to prominent theories of motivation in management.     

Non-stationary additive utility and time consistency

Within a continuous time life cycle model of consumption and savings, I study the properties of the most general class of additive intertemporal utility functionals. They are not necessarily stationary, and do not necessarily multiplicatively separate a discount factor from “per-period utility”. I prove rigorously that time consistency holds if and only if the per-period felicity function is multiplicatively separable in $t$, the date of decision and in $s$, the date of consumption, or equivalently, if the Fisherian instantaneous subjective discount rate does not depend on $t$. The model allows to explain “anomalies in intertemporal choice” even when the agents are time consistent and various empirical regularities. On the other hand, the model allows to characterize mathematically the “effective consumption profile” of naive, time-inconsistent agents.     

人口老龄化背景下的中国养老保险风险分析

伴随着我国人口老龄化的不断加速,社会保障尤其是养老保险领域的压力也随之加大,我国当前的养老保险体系也存在着一些现实问题与不足之处。而这都将导致在养老保险体系中固有的筹资、基金投资运营风险上升,同时也将出现制度与政策等新的风险。文章认为,需加强风险管理,不断完善养老保险制度,才能积极应对风险与收益的平衡。     

Optimal Retirement with Increasing Longevity

We develop an optimizing life‐cycle model of retirement with perfect capital markets. We show that longer healthy life expectancy usually leads to later retirement, but with an elasticity less than unity. We calibrate our model using data from the US and find that, over the last century, the effect of rising incomes, which promote early retirement, has dominated the effect of rising lifespans. Our model predicts continuing declines in the optimal retirement age, despite rising life expectancy, provided the rate of real wage growth remains as high as in the last century.     

Does aging influence structural change? Evidence from panel data

Our study represents a first attempt to single out the effects of aging on the entire structure of the economy that is approximated by employment shares in different sectors. We find that even after controlling for the effects of other relevant factors - e.g., income per capita, share of trade in GDP, government consumption share in GDP, population size - aging does have a statistically significant differentiated impact on the employment shares. In particular, we find that an increase in aging exerts a statistically significant adverse effect on the employment shares in agriculture, manufacturing, construction, and mining and quarrying industries. At the same time, an increasing share of the elderly (decreasing share of the youth) in society positively affects employment shares in community, social, and personal services as well as in the financial sector.     

人口年龄结构与住宅价格调控

在人12老龄化背景下．当人12总量和年龄结构发生质的变化时,将对住宅价格产生深远影响。本文在人口学研究基础上。有效结合住宅销售价格指数．通过逐步回归的方法获得购房适龄人口数量与住宅价格的关系模型,同时创新性地纳入莱宾斯坦人口发展五阶段理论,通过Logarithmic曲线模型进行量化分析。结论显示,在假定条件下．随着未来适龄购房人口的减少,国内住房价格将在2018年出现拐点并逐步回落,并在2030年前后降至2000年水平（剔除通胀因素）,之后将处于长期低迷状态。因此当前在遏制住房价格过快上涨的同时,应从更长远的视角构建调控思路。     

Exploring heterogeneity in travel time expenditure of aging populations in the Netherlands: results of a CHAID analysis

The aim of this paper is to contribute to the increasing literature on travel behavior and time use of the elderly. The Dutch National Travel Survey, administered in 2009, was used as a data source. First, various facets of activity-travel patterns of the elderly were compared against overall sample averages. Results indicate that the new generation of elderly people do not differ that much from other age groups in terms of their activity-travel behavior. Differences in behavior can be largely understood in terms of constraints acting on agendas. Moreover, travel patterns of elderly are affected by socio-demographic variables. Second, to further qualify the average findings, the Chi-square automatic interaction detection (CHAID) method was applied to explore heterogeneity among the elderly in terms of travel time expenditure. It is analyzed how differences in travel time co-vary with socio-demographics, in addition to activity type, activity duration and travel aspects. The results suggest that the aging population can be systematically broken down into several homogeneous cohort segments. Travel time of elderly groups depends significantly on transport modes, travel motivation, and seven socio-demographic variables (gender, age, living environment, personal net-income, household size and season). Moreover, there is less heterogeneity in travel time of elderly who are older than 75 years old. However, for younger elderly people, especially the group aged from 65 to 74 years old, heterogeneity affects their travel.     

养老机构发展呼唤创新——基于北京市海淀区养老机构的调研

由于老龄人口剧增,加之社会转型、政府职能转变和家庭养老功能弱化,老年人群,特别是高龄和带病老年人对于社会服务的需求迅速增长,这无疑给现存的养老服务体系带来巨大的冲击和压力。通过对北京市海淀区养老机构长达数月的调研,我们了解到目前入住老人大多身患多种疾病,身体状况普遍较差,大部分老人选择入住养老机构是出于自己的意愿,但是,老人的收入水平限制了其对机构养老方式的选择。通过调研我们还发现,现存养老机构发展面临着资金不足、经营困难以及许多体制性障碍,为促进养老机构发展,在加大投入力度、加快投入步伐、创新投入方式满足社会对养老机构的需求外,应强化保障性养老机构中政府的作用和理顺养老机构的管理体制。此外,由于短时间内,大幅度增加养老机构确有困难,可以规范管理社会化居家养老服务,起到一定的补充、替代作用。

Comparative analysis of health care costs in Japan and the United States: a simulation of productivity and savings behavior

Japan and the United States, though contrastive in terms of the percentage of the elderly in their population and the ratio of their health care costs to GDP, both face soaring medical expenditures. Sato et al. [Health Care Systems in Japan and the United States: A Simulation Studies and Policy Analysis. Kluwer Academic Publishers, Hingham, MA] developed a model to solve this problem by increasing the productivity of the non-health care sector. This study has applied that model to estimate national savings, and compared these savings with estimated health care costs. The results show that in order for savings to exceed expenditures the US needs to have a higher savings rate and a higher interest rate than Japan.
