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。     

A global meaning of supply chain social sustainability

Abstract

The purpose of this research is to help reduce tensions in supply chain social sustainability (SCSS) decisions by providing a common global, contextual definition of social sustainability. This exploratory study utilised an inductive structured interview method to capture SCSS concept meanings. Those interviewed are from, have lived, and worked in developed economies, emerging economies and the base of the pyramid (BOP) economies. The results present a new global baseline definition of SCSS to inform theory and practice by finding that SCSS meanings differ not only between the different levels of economic development, but also within the levels as well. Culture, community and whether basic human needs are met all weigh into perspectives of what this concept is and should entail; a broad, contingent definition is most appropriate moving forward for sustainability planning and execution. Further research with stakeholders in more countries and communities is needed to validate our proposal.     

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。     

Skill and education effects on earnings in 18 Countries: The role of national educational institutions

This study investigates whether the mechanisms why education is rewarded vary across countries. Do educational institutions affect the likelihood that support for a particular mechanism is found? Combining IALS survey data and OECD statistics on educational institutions, it was shown that the effect of measured skill on earnings - controlled for educational attainment - is lower in countries where educational institutions produce skills relevant for work through the vocational system. This indicates that the human capital perspective on education works particularly well in vocationally oriented educational systems, as the skills generated in education are strongly overlapping with the skills that are rewarded. An alternative mechanism sees education as a means for social closure through credentialization. Under the credentialization model, education is not primarily rewarded for the productivity-enhancing skills it entails, but rather for reasons unrelated to productivity. Following this theory education is used for selection into the organization, after which directly observable skills are determining wages. Assuming that a strongly differentiated educational system creates boundaries between social groups, it is hypothesized that strongly differentiated systems lead to stronger measured skill effects. We do not find support for this hypothesis.     

对《劳动合同法》立法宗旨的认识

《劳动合同法》从立法之初,其立法宗旨就引发了社会各界的激烈争论,主要集中在立法根据以及＂单保护＂还是＂双保护＂等问题上。应从倾斜保护的角度认识《劳动合同法》的立法宗旨,即《劳动合同法》既不是＂单保护＂,也不是＂双保护＂,而是在保护劳动者权益的同时,兼顾保护了用人单位的利益。     

《诗经·大雅·民劳》主旨考辨

《诗经·大雅·民劳》的主旨迄今主要有四类观点。之所以产生这四种不同的观点,根源就在于历代学者对诗中的＂小子＂一词以及诗文本内在逻辑的理解有不同。通过综合考察诗中＂小子＂一词的含义与诗文本的内在逻辑关系,得出两点结论：一、诗中的＂小子＂不是指代周王,而是指作者的同僚。二、作者通过此诗表达了对同僚的殷切期望。
