资本回报率、人力资本投资与收入不平等——基于Galor-Zeira模型的扩展

资本回报率下降对人力资本投资、收入不平等程度有较大影响。本文将可变资本回报率加入Galor-Zeira模型,理论推导发现:收入不平等陷阱并非不可逾越的障碍。当技能劳动力工资高于受教育固定成本时,随着资本回报率下降,接受教育的遗赠临界水平将降低,更多家庭将发现投资人力资本是有利的,稳态的技能劳动力比例将提高。在当前资本回报率下降的大背景下,提高技能劳动力工资、降低受教育成本、对教育贷款实施财政减免优惠、为农村中等教育支出减负和提升农村教育质量、倡导节俭和重视遗赠的文化氛围在长期都有助于提高技能劳动力比重以及缓和收入不平等。     

Cooperative conversion and communalization: Closely observed interactions between the material and the mental

Various authors, including Elinor Ostrom, have shown that the legal form of a cooperative has many of the characteristics of a Common. Here we focus on cooperative conversion, through which conventional enterprises become labor‐managed firms (LMFs), viewing it dynamically as a communalization process. These processes are addressed in the light of a field survey carried out in France, looking at six firms involved in cooperative conversion. The changes entailed are two‐dimensional, both material and mental. This is visible, for example, when finding the capital to mount an LMF: members of the workforce must draw on their own funds; they must also believe in the project. Through our empirical observations we highlight the obstacles in the way of forming an LMF. In particular participants must undertake a work of negotiation hinging on stakes marked by the two, largely inseparable dimensions. Ultimately we query the ethic brought into play in the collective action of constituting a Common. Specifically, individuals must contribute to a collective action underpinned by principles of self‐governance, or commoning, the rock on which the Common rests. A key finding of our study is to demonstrate that a Common can only be successfully created if the constituent processes are consistent with the overall goal. In other words the manner in which we travel is inseparable from our final destination; otherwise we shall surely lose our way.     

Human resource management practices and voluntary turnover: a study of internal workforce and external labor market contingencies

We tested relationships between employee quit rates and two bundles of human resource (HR) practices that reflect the different interests of the two parties involved in the employment relationship. To understand the boundary conditions for these effects, we examined an external contingency proposed to influence the exchange-based effects of HR practices on subsequent quit rates – the local industry-specific unemployment rate – and an internal contingency proposed to shape employees’ conceptualization of their exchange relationship – their employment status (i.e. full-time, part-time and temporary employment). Analyses of lagged data from over 200 Canadian establishments show that inducement HR practices (e.g. extensive benefits) and performance expectation HR practices (e.g. performance-based bonuses) had different effects on quit rates, and the former effect was moderated by unemployment rate. The effects of HR practices on quit rates did not differ between FT and PT employees, but a different pattern of main and interactive effects was found among temporary workers. These findings suggest that employees’ exchange-based decisions to leave may be less affected by the number of hours they expect to work each week, and more by the number of weeks they expect to work.     

延迟退休年龄下隔代抚育与劳动参与的抉择*——基于工资收入随机性假定的研究

隔代抚育会对延迟退休年龄政策在促进劳动力供给上产生挤出效应。为了对此进行验证，本文在工资收入随机性的假定及延迟退休5年的情景下，模拟了面临孙辈照护需求的女性临近退休者提前退休所产生的福利变化。进一步，本文采用CHIP和CHARLS的微观调查数据，对不同群组的收入增长率和收入风险进行了估计，继而分析了当面临孙辈照护需求时这些收入特征对退休决策者制度退休和退休后劳动参与抉择产生的影响。总体上，在延迟退休年龄政策下，隔代抚育将对女性劳动力供给产生挤出效应。当面临孙辈照护需求时，女性临近退休者的制度退休抉择主要受自身收入增长率和收入风险的影响，收入增长率越低，或收入风险越高，她们提前退休的意愿就越强烈；制度退休后的劳动参与则更多地受子女收入增长率的影响，子女收入增长率越高，劳动参与的概率越低。     

现阶段我国农村剩余劳动力转移途径分析

随着农业生产率的提高，农村劳动力的隐性失业问题也日益显露出来，并逐渐成为限制中国经济整体发展的重要因素。本文对农村剩余劳动力转移的传统途径所面临的新问题做细致分析，同时提出以三化(城镇化、工业化、知识化)互动、整体推进的方式来解决农村剩余劳动力问题的新途径，并提出确保三化互动得以实施的若干相应对策。     

Resistance to Trade Liberalization in Unionized Sector

This paper studies the lobbying against trade liberalization by both a firm and a union in the same industry. We find that the relationship between their political activities depends on the effect of political activity by one on the marginal effectiveness of political activity by the other. We also show that, when they are strongly risk-averse and their political activities are strategic complements, trade liberalization is likely to be successful if business is brisk, the foreign firm's production cost is high or the number of union members is small. However, when they are not strongly risk-averse, these results hold reversely.     

Is the Optimal Labor Income Tax Progressive in a Unionized Economy?*

This paper concerns optimal nonlinear labor income taxation in an economy with union wage setting and endogenous hours of work. The purpose is to study the determinants of tax progression. We show that the optimal degree of progression of the labor income tax depends on the extent to which the government can influence the wage rate via tax policy as well as on its ability to redistribute income across individuals. In addition, the argument for progressive labor income taxation depends on whether hours of work are chosen by the employed themselves or the union.     

规范劳动合同制是地勘单位用工制度改革的关键

文章认为,计划经济体制下形成的,地勘单位采用行政命令配合思想政治工作的方式,对固定职工进行各个用工环节的管理模式,已不适合市场经济条件和经济全球化的要求,地勘单位必须规范劳动合同制管理,进行用工制度改革。文章分析了地勘单位劳动管理现状,论述了实行劳动合同制管理的必然性和紧迫性,以及现今地勘单位在规范劳动合同管理方面存在的差距。最后提出了地勘单位规范全员劳动合同制管理的四项措施建议。     

社会资本与农村剩余劳动力转移问题分析

社会资本是一种与物质资本、人力资本相区别的存在于社会结构中的个人资源,它对个人的发展与进步具有重要的作用。随着农村整体社会资本的下降,我国的农村剩余劳动力转移难度加大。如何提升农村劳动力的社会资本,进而推进农村剩余劳动力转移,是关系我国农村经济发展一个重要问题。     

我国经济发展水平与劳动力就业数量关系研究——兼论我国劳动力资源是否过剩

我国劳动力对经济发展而言，其生产率高于资本，因而经济发展对劳动力就业的促进作用逐渐减弱（经济增长的就业弹性逐渐变小）。据测算，我国2013年以前劳动力就业压力很大，2015年以后劳动力又会供不应求。所以，我国未来经济发展中，2014年前后应采用不同的产业结构调整策略来充分满足劳动力就业的要求。
