论知识与知识性劳动

本文针对知识经济来临时代一些人对价值源泉的模糊认识,结合新的实际,在马克思主义经济学理论框架内对知识、知识性劳动进行了分析,在新的经济条件下发展了商品二因素理论和劳动二重性理论.在知识经济时代,人类劳动的主体形式从体力劳动转向智力劳动,知识成为当代经济发展的重要因素,但价值的源泉仍旧是人类劳动.本文通过区分知识和知识性劳动,澄清了模糊认识,阐明是知识性劳动创造了价值,而不是知识创造了价值.知识性劳动就是人们不断探索的劳动,从而知识经济的本质是创新,只有坚持劳动价值论,我们才能在知识经济社会中建立一个以人为本的、不断创新的经济运行机制.     

The econometrics of female labor supply and children

This is a survey of applied econometric research on the effects of children on female labor supply. Reasons for interest in the topic, and a basic model and terminology, are reviewed. Concerns are raised about the possible endogeneity of child status variables, and about the instrumental variables approach for dealing with this problem. Alternative ways of conceptualizing and estimating child status effects are considered, together with selected empirical evidence. Relevant developments from the household demand literature are summarized. Basic issues of model choice are also discussed.     

指数分析中多种方法的结合运用

指数分析法在经济分析的各个领域里已得到广泛的应用。但只用单一方法分析问题往往不够全面、深入。本文以工业劳动生产率的分析为例,从三个方面,多角度、多层次、比较系统地阐述了指数分析中独具特色的分析手法。     

The Big Five personality factors and team performance: implications for selecting successful product design teams

In the pursuit of faster product development, product design teams are a growing phenomenon in many organizations. In order to be successful, these teams must be composed of people who work well together. However, despite the benefit of selecting the optimal combination of team members, this topic has received little attention. Personality has been identified as a potentially helpful selection variable in the determination of optimal team composition. This study examines the relationships between the ‘Big Five’ personality factors (Conscientiousness, Extraversion, Neuroticism, Agreeableness, and Openness to Experience) and objective team performance for three-member product design teams. In addition to this, the potential incremental contribution of personality to the variance in team performance over that accounted for by established selection measures such as general cognitive ability was investigated. In the short duration of the study, it became apparent that some teams were capable of success, and some were not. Successful teams were characterized by higher levels of general cognitive ability, higher extraversion, higher agreeableness, and lower neuroticism than their unsuccessful counterparts. In successful teams, the heterogeneity of conscientiousness was negatively related to increments in product performance. Implications for the selection of product design teams and future directions for research are discussed.     

What types of occupations are women entering? : Determinants of changes in female representation: 1970–2000

Although a consistent body of research has demonstrated that occupational segregation is highly consequential for women's economic standing, we know little about the processes that contribute to changes in levels of sex segregation. In this study, we examine those factors that contribute to changes in the percent of women in detailed occupational categories in the United States. Since we are most concerned with the economic consequences of this type of segregation, we analyze a group of high-paying, male-dominated occupations that, if better integrated, would contribute most to earnings equality. We find that occupations to which relatively high percentages of women aspired and occupations that are growing have been experiencing above-average increases in the percentage of women, while occupations characterized by male-stereotyped task profiles have been witnessing below-average increases. Additionally, our results suggest the presence of a ceiling effect: it is easier for women to break into male-dominated occupations initially than to sustain growth. Our analysis suggests that both supply and demand-side explanations provide insight into the processes contributing to increases in the occupations that we examine, although it can be very difficult to distinguish between supply and demand-side elements; indeed they may occur simultaneously.     

劳动合同服务期规则的适用——以海南省某企业招聘信息为切入点

海南省某企业在其招聘广告中要求劳动者承诺终身服务,涉及服务期规则的适用问题。现行《劳动合同法》存在对劳动者过度保护的倾向性,劳动者约束性条款数量较少。而服务期规则作为用人单位长期留用人才的唯一法律依托,存在着可设定服务期的事项范围过窄、违约金条款不具有应有惩罚性的问题。服务期规则的不健全把企业吸引和培育人才的手段引向异端。司法实践中出现了对现行服务期规则进行突破的裁判或未突破现行规则但裁判结果有违诚信原则的情况。针对现状,建议拓宽可设定服务期的事项范围、改进违约金规则使其具有惩罚性来保障企业人力资本投入上的合理利益,同时规定最长服务期限来维护劳动者基本权益,从而最大限度地维持劳资双方利益平衡。     

布莱尔对英国工党与工会关系的定位与调整论析

基于1980年代以来工党和保守党处理工会问题的经验教训以及工会的新变化,1994年出任工党领袖的布莱尔把对工会的定位由工党的劳工运动盟友转变为社会合作伙伴,对工会开始采取疏远和强硬的态度,尽力削弱附属工会在党内的权力。布莱尔对工党与工会关系的调整总体上是成功的,但也产生工党失去身份特征、核心选民减少等问题,对此要给予全面辩证地认识。     

高职院校学生顶岗实习中的人身伤害问题及法律保障

顶岗实习是学生在完成文化基础课、专业课以及校内专业实践课以后所进行的实践性教学环节。由于我国法律法规对顶岗实习学生合法权益尚未完善，导致顶岗实习学生在发生人身意外伤害事故时，维权非常困难。本文对顶岗实习的涵义、顶岗实习学生身份的界定和完善顶岗实习法律举措等几个方面的法律问题进行了探讨。     

Equilibrium Labor Turnover,Firm Growth,and Unemployment

This paper considers equilibrium quit turnover in a frictional labor market with costly hiring by firms, where large firms employ many workers and face both aggregate and firm specific productivity shocks. There is exogenous firm turnover as new (small) startups enter the market over time, while some existing firms fail and exit. Individual firm growth rates are disperse and evolve stochastically. The paper highlights how dynamic monopsony, where firms trade off lower wages against higher (endogenous) employee quit rates, yields excessive job‐to‐job quits. Such quits directly crowd out the reemployment prospects of the unemployed. With finite firm productivity states, stochastic equilibrium is fully tractable and can be computed using standard numerical techniques.     

Rhetoric and Reality of Economic Self-sufficiency Among Rural,Low-Income Mothers: A Longitudinal Study

This study examined the contributions of maternal labor force participation and marital status on economic self-sufficiency over time for rural mothers. Data were from 174 rural families participating in three waves of data collection in Rural Families Speak. χ ² and multiple logistic regression were utilized. Results revealed only one-third of mothers moved toward economic self-sufficiency over three years. Maternal education, employment status, and weekly work hours were associated with improved economic well-being. Compared to single-parent families, unmarried-couple and married-couple families had increased odds of improving economically. In an analysis of all mothers with partners, married or unmarried, martial status was not significant in economic improvement. Findings suggest the role of marriage in welfare reform for rural families should be reconsidered.
