Poverty Traps, Indeterminacy, and the Wealth Distribution

We consider a one-sector growth model in continuous time with a production externality and endogenous labor supply. There is a continuum of households who have identical preferences but differ with respect to their initial wealth. We show that there exist economies such that an indeterminate steady state exists for some wealth distribution but not for others. A second result is that a redistribution of wealth may drive the economy from a steady state with strictly positive output to a poverty trap in which output converges asymptotically to zero. These results indicate that differences in the wealth distribution may be responsible for drastic differences in the long-run standard of living.

Have Employment Relationships in the United States Become Less Stable?

There has been considerable debate as to whether job stability has declined in the United States. This paper uses data from the Survey of Income and Program Participation (SIPP) to examine the incidence of labor market turnover between 1986 and 1993. Specifically, we calculate one- and two-year separation rates and then analyze turnover by the source of separation. We find that the incidence of job separations did not increase over the period under investigation, but appears to have declined somewhat. When analyzing separations by reason, conditional on separating from an employer, we find little evidence of temporal changes in the composition of turnover that would indicate greater employment instability. Therefore, we do not find conclusive evidence that employment relationships have become more unstable in the recent past.      

就业体制改革不应忽视内部劳动力市场

本文吸收了西方劳动经济学和企业理论的新成果，论述了内部劳动力市场的基本原理，重新审视了我国以往的就业体制改革思路及其成本与收益．提出发展内部劳动力市场是当前深化我国就业体制改革亟待解决的一个重要问题，并阐述了若干具体的操作思路。     

生产劳动力的劳动时间的探讨

传统经济学的劳动力价值理论只有生产劳动力的生产费用(物化劳动),没有生产劳动力的劳动时间(活劳动)的耗费。劳动力的生产也有劳动时间的耗费。劳动力的自然再生产时间不形成劳动力的价值,劳动力的社会再生产时间、即学习劳动的时间形成劳动力的价值。劳动力价值包括两个部分:一是生产劳动力的物化劳动,如生活费用和学习费用等;二是生产劳动力的活劳动即学习劳动。     

我国农村劳动力转移面临的困难及对策

由于农村剩余劳动力数量庞大而素质较低，再加上观念认识不到位，组织管理工作滞后，就业环境不完善等，导致农村剩余劳动力转移困难，影响农民增加收入和农村小康社会建设。因此，必须采取多种措施，广辟就业渠道，优化就业环境，大力发展劳务中介组织，加强管理和协调，以使农村剩余劳动力有效有序地转移。     

从酸刺村看宁夏南部山区非农产业发展问题

过剩劳动力沉积于农业和农村是造成我国农村长期贫困的根源。宁夏南部山区的西海固由于历史和环境的原因，当地的贫困问题更为突出，发展非农产业来转移农村过剩的劳动力是解决这类地区贫困问题的根本途径。本文通过对宁夏南部西吉县酸刺村的调查分析来论述宁夏南部山区的非农产业发展问题。     

A multiregional model of China and its application

China's rapid economic transformation since 1979 has been accompanied by a stark regional disparity with the coastal provinces integrating swiftly into the world markets while inland regions lagging far behind in the industrialisation process. The growth imbalance has placed China's provinces into different stages of development and called for different policy responses to deal with different challenges they are facing. Similarly, a national policy initiated by the central government is likely to be interpreted and implemented in different ways when local governments take into consideration the different conditions in their localities. Therefore, it would be extremely valuable for policy makers and researchers to have an analytical tool that is capable of studying interactions among the provincial economies and the dynamic relationship between the centre and local governments. The multiregional econometric model of China presented in this paper is the first attempt to provide such a tool. The pioneering model consists of over 1200 equations, covering 30 provinces of China that are linked by inter-regional flows of goods and services. The model is used to study the impact of fiscal recentralisation in the 1990s. The counterfactual simulation results show that when China's central government diverted tax revenue from provincial governments, it achieved higher budgetary revenue for the central government but at the expense of lower overall budgetary revenue and slower economic growth.     

智力劳动的分配决定效应及模型

随着知识的积累与科技的进步 ,智力密集型劳动已经替代体力密集型劳动成为价值的最主要源泉。智力劳动的特征使得凝结在产品中的劳动含量与智力投资呈正相关 ,进而与其所形成的智力劳动力价值呈正向相关。因此 ,提高智力劳动力价值在分配决定机制中的权重 ,相对于现行以工龄为主体的工资决定体制而言 ,更能体现按“能”付酬原则 ,更能体现生产力的进步对分配的决定作用。以简单劳动力价值确定最低工资水平 ,然后依据每一阶次的智力劳动力价值差别确定工资水平差别 ,更能推动智力投资与劳动力资源的合理配置。以智力劳动力价值为基础的工资分配制度 ,可界定为一个基于贴现理论的微观静态分配模型。     

我国人口结构变化、资本偏向型技术进步与劳动收入份额演变 ——基于1990-2017省际面板数据的研究

在我国老龄化程度加深及出生率下降的背景下,从CES生产函数出发,构建理论模型,试图从人口结构、技术进步偏向角度探索我国劳动收入份额的演变机制。并通过我国1990-2017年省级层面数据的研究,表明我国要素间是互补的,技术进步偏向资本,我国人口结构的变化——老年抚养比上升及少儿抚养比下降对我国劳动收入份额产生了负面的影响。同时,我国技术进步的资本偏向性特征,降低了我国劳动收入份额。在控制了其他因素、分区域及剔除异常值进行检验后,结果仍然显著。     

关于我国企业目前实施CRM的理性思考

在绝大部分市场领域中 ,顾客已取得绝对的支配权。作为一种新兴的竞争手段 ,客户关系管理 (CRM)正备受瞩目。然而 ,作为一种先进的管理技术 ,ERP在中国的实施情况至少可以说是远远低于理论界和企业界的预期 ,ERP是CRM的物质和思想基础 ,同时CRM相对于ERP的实施具有更大的不确定性 ,这一不确定性主要来源于市场的不确定性。面对CRM的兴起 ,我们是否必要、是否有能力引进和实施CRM系统 ,还需要对实施CRM的成本收益和环境约束作出详细的分析。
