Older and More Engaged: The Mediating Role of Age‐Linked Resources on Work Engagement

In the era of a graying workforce, individuals and their employers are concerned with the impact of the graying workforce on the level of engagement at work. Contrary to the myths about older workers being less engaged, statistics have shown that the level of engagement is higher as people age. Within the broad framework of conservation of resources theory in the area of work engagement, the current study aims to clarify how older workers are more engaged at work than younger workers. Building upon socioemotional selectivity theory and continuity theory from a life‐span perspective, we explain how individuals gain more resources as they age, including the abilities to regulate emotion and to maintain a career identity. We argue that this positive relationship between age and resources explains why older people have high levels of work engagement. We tested our predictions with a sample of 613 workers in the United States. The study demonstrates that well‐regulated emotion and strong commitment to career mediate the positive relationship between age and work engagement simultaneously. These findings contribute to the understanding of an aging workforce's engagement in the workplace. © 2016 Wiley Periodicals, Inc.

异质性厂商合作研发的最优投入水平及其成本分摊机制

在产品差异化的Betrand模型中引入具有需求创造效应的创新,构建一个异质性厂商进行合作研发和价格竞争的两阶段动态博弈模型,研究异质性厂商合作研发的最优研发投入以及研发成本的分摊机制.研究发现,异质性厂商间合作研发的最优研发投入水平和成本分摊比例主要取决于市场容量、自身价格效应、交叉价格效应及研发的需求创造效应;根据自身价格效应、交叉价格效应及研发的需求创造效应确定合作研发成本的分摊比例时,基于Betrand竞争的异质性厂商通过合作研发可以提高其均衡价格、产量和利润.     

城市与区域关系演化过程及新时代特征

城市与区域关系是定位和指导城市与区域发展的立足点,理清城市与区域关系是实现科学发展的重要保障。分析城市与区域的基本关系及其演化动因和演化过程,以此考察我国传统的城市与区域关系特点,以及全球化与知识经济时代城市与区域关系的新特征和发展趋势,指出我国城市与区域关系处于区域框架指导下的城市主导发展时期;新时期,城市的功能性和区域的整体性是城市与区域关系的核心。在一定时期内,我国城市与区域对立统一关系依然存在,同时,随着城市实体地域与功能地域的空间扩展,城市与区域的边界趋于模糊,城市与区域地理单元走向交织缠绕和相互融合。     

Decomposition of new venture growth into firm age,survey period and vintage effects

Firm data are accumulated on a yearly basis. In view of the linear relationship of firm age?+?foundation year?=?survey year, the fluctuations of firm data classified by age and period cannot be decomposed into age, period and cohort (foundation year) effects. Three decomposition methods are briefly reviewed and applied to Japanese data on new ventures founded since 1995. Regarding sales and employment growth, the age effect is the largest with a downward trend, and the cohort effect is negligible. Regarding labour productivity, the age effect indicates upward movements, and the cohort effect is negligible. The reason of the negligible cohort effect is discussed.     

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.     

高校教师对延迟退休年龄意愿的实证研究——基于成都市高校教师的调查

通过PPS抽样从成都市随机抽取了九所高校,并就其专任教师对延迟退休年龄的意愿进行了问卷调查,得到影响成都市高校教师退休意愿影响因素的数据,建立了二维选择logistic回归模型。是否延迟退休年龄的主要影响因素为性别、收入、和身体健康状况。对赞成延迟退休教师的意愿退休年龄进行了分布检验,发现其服从正态分布,并预测出赞成延迟退休的男教师意愿退休年龄为64-65岁,女教师的意愿退休年龄为61-62岁。     

Battle royal in biotechnology: R&D vs. product vs. process innovations

Companies regard innovation as a central element of their business. However, as not all innovation types are the same, the central question is: should their announcements bring about the same effect on performance? This article analyses potential differences in firm value derived from the innovation-type announcements ‘R&;D’, ‘product’, and ‘process’, made by intensive news-generating firms such as biotech companies. The empirical application shows a significantly positive reaction to innovation announcements, with the prospect of future innovation (‘R&;D’ investment announcements) having greater impact on firm value than ‘product’ and ‘process’ innovations. Firm experience also acts as a moderator in this innovation–performance relationship, which is particularly relevant for entrepreneurs who need to develop and send credible signals indicating the value of the firm's intangible assets to the market.     

Policy Discrimination with and without Interpersonal Comparisons of Utility

Can the Pareto criterion guide policymakers who do not know the true model of the economy? If policymakers specify ex ante preferences for agents, then Pareto improvements from a distorted status quo are usually possible, and with more commodities than states, one can implement almost every Pareto optimum. Unlike the standard second welfare theorem, planners cannot dictate allocations: agents must trade. Unfortunately ex ante preferences impose interpersonal comparisons. If policymakers merely aim to maximize some social welfare function then optimal policies form an open set; hence small changes in the environment do not necessitate any policy response. Planners with symmetric information about agents can sometimes intervene without making interpersonal comparisons.
