马克思主义政治经济学研究对象探析

任何一种理论的产生都来源于实践,任何一种理论的价值都在于指导实践.诞生于十九世纪三、四十时年代,成熟于十九世纪七十时年代并充分反映"资本主义生产方式以及和它相适应的生产关系和交换关系"的马克思主义政治经济学也面临着时代所赋予的挑战.在坚持马克思主义政治经济学理论的基本框架的前提下,马克思主义政治经济学研究对象的内容应扩大化、深化和细化,以适应社会发展的需要.     

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.

Did State Children’s Health Insurance Program Affect Married Women’s Labor Supply?

While the relationships between health insurance and the labor supply of women have been explored in the literature, little is known about the effects of offering public health insurance on the labor supply decisions of married women. This paper examines how the enactment of the State Children’s Health Insurance Program (SCHIP) affected the labor supply decisions of married women. Our empirical analysis showed that certain groups of married women reduced their number of hours worked upon SCHIP implementation. The results imply it is possible that some wives decreased their labor supply in order to make their children eligible for public health insurance.

Labor force participation and juvenile delinquency in Taiwan: a time series analysis

This study examines the null hypothesis of Granger no-causality between labor force participation (LFP) and juvenile delinquency in Taiwan. In order to explore this issue more thoroughly, this study adopts the approach proposed by Toda and Yamamoto (1995, Journal of Econometrics, 66(1–2), 225–250). It uses official time-series data provided by the Government of Taiwan. After estimating both a four- and five-variable VAR system, one that substitutes both male and female LFP rates for the aggregate LFP rate, the primary findings of this study reveal the following: The higher the past juvenile crime rate, the lower the future aggregate and female LFP rate will be. In addition, the higher the past male LFP rate, the higher the future juvenile crime rate will be. These findings are quite robust in terms of different lag-length structures.

A Stochastic Goal Program for Employee Scheduling*

Deterministic goal programs for employee scheduling decisions attempt to minimize expected operating costs by assigning the ideal number of employees to each feasible schedule. For each period in the planning horizon, managers must first determine the amount of labor that should be scheduled for duty. These requirements are often established with marginal analysis techniques, which use estimates for incremental labor costs and shortage expenses. Typically, each period in the planning horizon is evaluated as an independent epoch. An implicit assumption is that individual employees can be assigned to schedules with as little as a single period of work. If this assumption violates local work rules, the labor requirements parameters for the deterministic goal program may be suboptimal. As we show in this research, this well-known limitation can lead to costly staffing and scheduling errors. We propose an employee scheduling model that overcomes this limitation by integrating the labor requirements and scheduling decisions. Instead of a single, externally determined staffing goal for each period, the model uses a probability distribution for the quantity of labor required. The model is free to choose an appropriate staffing level for each period, eliminating the need for a separate goal-setting procedure. In most cases this results in better, less costly decisions. In addition, the proposed model easily accommodates both linear and nonlinear under- and overstaffing penalties. We use simple examples to demonstrate many of these advantages and to illustrate the key techniques necessary to implement our model. We also assess its performance in a study of more than 1,700 simulated stochastic employee scheduling problems.     

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。     

丹麦劳动力市场模式分析

丹麦劳动力市场模式是近年来国际劳动力市场模式中非常成功的一种模式,日益受到国际社会的关注。“丹麦模式”的基本特征是将灵活化的劳动力市场、慷慨的福利制度与积极的劳动力市场政策有机结合在一起构成了一个“金三角”,成功地平衡了劳动力市场的灵活性与安全性。丹麦劳动力市场模式以其传统的价值理念、良好的社会合作机制和混合经济体制为基础。随着全球化时代社会经济条件的变化,丹麦劳动力市场模式也面临着严峻的挑战。     

资源生产率视角的经济增长模型分析

现代经济的增长需要我们从关注资本和劳动生产率转移到关注资源生产率.发展以资源生产率为本质的循环经济,提高资源生产率有助于减缓经济增长中出现的环境问题,以使经济环境可持续发展.     

论建设社会主义和谐社会必须以科学发展观为指导

以科学发展观为统领,建设社会主义和谐社会,是中国共产党人在新世纪新阶段的重大战略任务。建设社会主义和谐社会要坚持以科学发展观为指导,大力发展先进生产力、先进文化,正确处理好人民内部的矛盾。同时,要进一步深化经济体制、政治体制、教育文化体制和社会管理体制等方面的改革,按照科学发展观所贯穿的基本原则和精神,不断开拓建设社会主义和谐社会的新思路和新境界。     

产业协同集聚的资源错配效应研究

利用2003－2016年中国280个地级市的数据,分别测算了产业协同集聚指数、资本错配和劳动力错配指数,采用差分GMM方法考察产业协同集聚对资源错配的影响。结果发现：产业协同集聚的提高,会显著降低资本错配和劳动力错配指数;分地区的回归发现,东部地区产业协同集聚改善了资本错配,对劳动力错配负向作用不显著,中部地区产业协同集聚会改善资本错配,但会恶化劳动力错配,西部地区产业协同集聚则加剧了资本错配,但可以缓解劳动力错配情况。进一步作用机制分析表明,产业协同集聚水平的提高,会显著提高金融业的专业化分工,进而改善资本错配,同时会提高劳动力成本,改善劳动力错配。文章的政策含义是通过产业协同集聚,可以提高金融业的专业化分工和劳动力成本,进而缓解资本和劳动力的错配,提高经济效率,促进经济增长。
