国外农村劳动力迁移理论的演变与发展

根据对农村劳动力迁移决策的不同解释,把国外有关劳动力迁移的主要文献分为三类:传统的劳动力迁移理论(包括刘易斯模型、拉尼斯-费景汉模型、托达罗模型)、人力资本劳动力迁移理论和新劳动力迁移理论.目前国内研究劳动力迁移的文献主要以传统劳动力迁移理论和人力资本劳动力迁移理论为研究基础,而对新劳动力迁移理论的借鉴和应用还比较罕见,因此值得我们学习和研究.     

Perpetual youth and endogenous labor supply: A problem and a possible solution

In the “perpetual youth” overlapping-generations model of Blanchard and Yaari, if leisure is a “normal” good then some agents will have negative labor supply. We suggest a solution to this problem by using a modified version of Greenwood, Hercowitz and Huffman’s utility function. The modification incorporates real money balances, so that the model may be used to analyze monetary as well as fiscal policy. In a Walrasian version of the economy, we show that increased government debt and increased government spending raise the interest rate and lower output, while an open-market operation to increase the money supply lowers the interest rate and raises output.     

影响农村三种非农就业途径的主要因素研究--对天津市农村社会的实证分析

文章探讨了影响农村劳动力非农就业倾向的主要因素。研究结果表明,区位条件对农村劳动力非农就业倾向的影响,主要表现为近城地区以大量企业及相对发达的各种要素市场为第一优势,吸纳了更多劳动力进入本地企业就业。教育总体上是影响农村劳动力非农就业倾向的最重要因素。但其在近城地区的影响却位居第二。在远城地区教育对增大农村非农就业倾向的作用更为显著,而且受教育程度越高这种倾向就越显著。各种文化水平的影响都普遍促进了劳动者到外地企业就业,但对进入本地企业就业和家庭非农经营的促进却并不普遍,其中初中教育对农民在本地企业就业的作用更显著些;高中教育提高农民从事非农家庭经营的倾向最为明显。耕地数量抑制农户劳动力外出务工,但对其在本地企业就业和家庭非农经营的影响也不显著。乡镇企业的发展增大了农民进入本地企业的就业倾向,劳动者供养的非劳动人口数量对农民非农就业的正向影响不显著,农户拥有的非农业和农业生产性资产对农村非农就业的影响不大。因此,加快推进农村城镇化;加强边远农村地区的中等教育,特别是职业技能教育;大力发展乡企和私企;完善农村社会保障体系;构建农村劳动供求信息系统等,是促进农村劳动力加速向非农产业转移的重要途径。     

改善劳动力市场管制的几个问题探讨

对劳动力市场的管制是政府监管市场的一个重要方面。本文通过对目前我国劳动力市场建设及运行、管制中存在的主要问题的分析,探讨了放松对劳动力市场的管制及管制的着力点。笔者认为,政府放松对劳动力市场管制是劳动力市场运行规律及WTO规则的要求,而管制的着力点应主要放在强化制度供给、弥补市场失灵、保护劳动者的合法权益等方面。     

家庭非农劳动供给时间的影响因素分析

非农劳动供给在家庭中占有非常重要的地位。本文利用四川和安徽12年12乡的农户调查数据,采用Heckman两阶段模型,对影响家庭非农劳动供给的因素做了实证分析。研究结果表明,年龄轻、家庭平均受教育程度高、家庭初始经济能力有利于家庭非农劳动供给决策和非农劳动时间的增加;家庭中男女劳动力的比例对非农劳动供给时间具有不同的影响,土地资源匮乏是家庭从事非农劳动供给的重要原因。文章认为,政府应当在教育培训、信贷支持、通讯设施建设方面加以完善,以增加农户家庭的非农劳动供给。     

Feminist Ecological Economics and Sustainability

Synopsis New developments in feminist ecological economics and ecofeminist economics are contributing to the search for theories and policy approaches to move economies toward sustainability. This paper summarizes work by ecofeminists and feminist ecological economists which is relevant to the sustainability challenge and its implications for the discipline of economics. Both democracy and lower material throughputs are generally seen as basic principles of economic sustainability. Feminist theorists and feminist ecological economists offer many important insights into the conundrum of how to make a democratic and equity-enhancing transition to an economy based on less material throughput. These flow from feminist research on unpaid work and caring labor, provisioning, development, valuation, social reproduction, non-monetized exchange relationships, local economies, redistribution, citizenship, equity-enhancing political institutions, and labor time, as well as creative modeling approaches and activism-based theorizing.      

Anticipated Environmental Policy and Transitional Dynamics in an Endogenous Growth Model

This paper makes a new attempt toinvestigate how an anticipatedenvironmental policy governs the transitionaldynamics of an economy when pollutionexternality is taken into account. Themodeling strategy we use is an AK technologyendogenous growth framework with an endogenousleisure-labor choice. It is found that, unlikeinelastic labor supply framework, a rise inpublic abatement expenditure will stimulate thebalanced economic growth rate. It is alsofound that public abatement technology plays animportant role in determining the transitionaladjustment of the economic growth rate inresponse to a pre-announced environmentalpolicy.     

Youth labor market expectations and job matching in sub-Saharan Africa: evidence from school-to-work transition surveys

In this paper, we investigate the factors that influence youth labour market expectations and outcomes. We also perform a job matching exercise to understand youth labour market dynamics in Sub-Saharan Africa. Our results show that youth education is an influential factor of youth employment expectations and employment, ceteris paribus. Higher educational attainments have a great impact on expecting and securing better jobs, particularly in the technical and professional fields. Youth with low educational attainments, particularly primary education and lower, have a higher tendency to expect to be employed in occupations with low job complexity. Our results indicate a severe job-skill mismatch in all occupational categories, both before and after the youth’s transition into the labour market. Using education as the only selection criterion, we found that less than 10 per cent of employment expectations match with skills required while 55 per cent and 34 per cent are under or over-educated for the jobs expected, respectively. Over and under education is a notable feature in youth labour markets in Sub-Saharan Africa. About 47 per cent of employed youth in the sample are overqualified for their respective jobs while 28 per cent are under qualified.     

贸易自由化、人口流动与地区犯罪率

文章探讨了中国贸易自由化进程对犯罪活动的影响及其发生作用的机制。研究基于中国产品层面的关税数据，构建差异性的地区贸易保护指标，衡量各地区贸易自由化程度，进而利用2000-2011年省级面板数据，运用固定效应模型与工具变量法实证检验贸易自由化与犯罪率之间的关系及潜在人口流动的影响机制。结果表明：中国加入WTO后，贸易自由化显著推升了犯罪率水平，且贸易自由化程度越深入的省份，犯罪率提升程度越高，地区效应显著；贸易自由化主要通过增加外来人口流入等渠道推升了犯罪活动。因而，中国在进一步对外开放过程中，要注重处理好贸易自由化带来的负面效应和由此产生的额外社会成本，更加注重流动人口权益的保障，消除劳动力市场扭曲，最小化贸易自由化可能带来的不利影响。     

二元经济理论模型评述

大多数经济学家认为,发展中国家的经济结构具有二元的性质,即现代城市部门与传统乡村农业部门并存,并据此形成了二元经济结构发展模型,以解释经济发展过程中的城乡工农关系以及二元经济向一元经济的转换。文章对四个主要的二元经济模型进行了综述,并深入探讨了模型所体现的经济思想和政策含义,以期为解决中国实际问题提供新的思路。
