论就业机会产品失灵问题的政府治理

中国劳动力市场的典型特征是就业机会与劳动力资源之间的信息分布不对称，而就业机会实质上是一种公共产品。根据市场失灵理论，解决公共品市场失灵问题时政府与市场两条思路均可采用。文章沿袭自古典经济学家庇古以来的传统，认为应该引入政府的干预来解决就业机会的市场失灵问题．并在此基础上提出相应的建议。     

Income Redistribution with Well-Informed Local Governments

This paper examines the problem of redistributing incomeacross jurisdictions and to mobile workers within jurisdictionswhen local governments have better information than the centralgovernment about local production conditions. Under the centralgovernments optimal policy, the subsidies or taxes that localgovernments provide to mobile workers normally depend on whetherthese governments are net recipients or net donors of interjurisdictionalincome transfers. Moreover, the public-input decisions of somelocal governments are distorted. The analysis demonstrates thatit may not be desirable to harmonize social policies across jurisdictions,even when the beneficiaries are quite mobile.

作为中央党校“深化劳动价值理论”课题的子课题 ,本文通过对不同时期国际投资特点的剖析 ,分析了国际投资领域的价值分配格局的变化 ,认为发达国家虽然在分配格局中仍居主导地位 ,但随着发展中国家经济发展水平的提高 ,不公正的分配格局开始改变 ,发展中国家通过吸引外资和对外投资 ,提高了其在国际经济中的比较利益。     

中国地方政府债务权责划分:实践探索与改革建议

地方政府债务权责划分是一国分级财政体制的重要内容。实现中国地方政府债务的合法化已经成为解决当前地方政府债务问题的前提条件。地方政府债务的合法化不仅是债务融资权的界定问题,更是管理责任的归属问题。近年来中国某些地方已经开始自发地探索地方层面上的政府债务权责划分的方法。国家应尽快制定统一的法规,赋予地方政府合法举债权,但应严格控制债务规模、界定使用范围。应在财政部和省市县财政部门设立债务管理机构,明确地方政府的债务偿还及风险管理责任,加大债务监督力度。     

Do labor market institutions matter for business cycles?

Using panel data of 19 OECD countries observed over 40 years and data on specific labor market reform episodes we conclude that labor market institutions matter for business cycle fluctuations. Spearman partial rank correlations reveal that more flexible institutions are associated with lower business cycle volatility. Turning to the analysis of reform episodes, wage bargaining reforms increase the correlation of the real wage with labor productivity and the volatility of unemployment. Employment protection reforms increase the volatility of employment and decrease the correlation of the real wage with labor productivity. Reforms reducing replacement rates make labor productivity more procyclical.     

Neighborhood quality and labor market outcomes: Evidence from quasi-random neighborhood assignment of immigrants

Settlement in a socially deprived neighborhood may hamper individual labor market outcomes because of lack of employed or highly skilled contacts. I investigate this hypothesis by exploiting a unique natural experiment that occurred between 1986 and 1998 when refugee immigrants to Denmark were assigned to municipalities quasi-randomly, which successfully addresses the methodological problem of endogenous neighborhood selection. I show that individuals sort into neighborhoods. Taking account of location sorting, living in a socially deprived neighborhood does not affect labor market outcomes of refugee men. Their labor market outcomes are also not affected by the overall employment rate and the overall average skill level in the neighborhood. However, an increase in the average skill level of non-Western immigrant men living in the neighborhood raises their employment probability, while an increase in the employment rate of co-national men living in the neighborhood raises their real annual earnings. This provides quasi-experimental evidence that residence-based job information networks are ethnically stratified.

Impact of the Sloping Land Conversion Program on rural household income: An integrated estimation

The objective of this study is to identify the pathways of the potential impacts of the Sloping Land Conversion Program (SLCP) on household income and quantify these impacts along the identified pathways. We fulfill this objective by developing an integrated analytic framework and using data collected from Wuqi county of Shaanxi for the period 2004–2010. This integrated analytic framework enables us to formulate a structural equation model for testing hypotheses regarding the direct and indirect impacts of the SLCP. It is found that the direct effect of the SLCP on household income is positive but very small and insignificant, suggesting that retiring cropland has, at least, not reduced income from farming. Moreover, the SLCP has had a much higher and even increasing indirect impact on household income through promoting labor transfer and relaxing liquidity constraints. Overall, the SLCP's total impact on household income ranged from 3% in 2004 to 9% in 2010 excluding the insignificant direct impact. The research and policy implications of our work are discussed.     

基于广义价值论的内生增长理论初探

增长理论是经济学的重要部分，关系到每一个人的福利和一个国家的地位。文章运用广义价值论研究经济增长问题，以分工为切入点，把分工产生的新增利益和该利益的公平分配统一起来，论述了递增性假设之外另一条增长的可能路径。主要结论如下：（1）基于比较优势的分工交换可以持续地产生比较利益即超过自给自足收益的净收益，这一收益不依赖于技术的递增或递减变化，具有普遍持久稳定性；（2）由分工交换产生的净收益构成原始积累的重要来源，既促进了生产规模和分工范围的扩大，又支持了研发和技术进步；（3）劳动生产力任何提高的效应都通过分工交换产生的比较利益加以放大，在一个分工交换系统中，行为主体提高比较优势产品和比较劣势产品的生产力分别具有正的和负的外部性；（4）基于广义价值论的内生经济增长体现了效率与公平的统一，一个好的制度是能够保证在交易中各方的比较利益率相等，掠夺性制度不仅直接损害经济增长，也不具备长期可持续性。     

Resource saving and productivity enhancing impacts of crop management innovation packages in Ethiopia

Crop management innovations are often not discrete fixed stand‐alone options—and their adoption may imply various combinations and adaptations. This potentially confounds their impact assessment. This article assesses the resource saving and productivity enhancing impacts of a crop management package revolving around minimum tillage in maize‐based farming systems in northwest Ethiopia. An endogenous switching regression model was applied to plot‐ and household‐level survey data collected from 290 rural households operating 590 maize plots during the 2012 production year. Controlling for variations in plot and household characteristics, the average effect of minimum tillage package (minimum tillage package) on maize productivity is 0.44 t/ha. Compared to conventional practice (CP), adoption of the MTP decreased the average male and female labor use in maize production by 14.4 and 8.2 person‐days per ha, respectively. Similarly, MTP adoption decreased draft power use for land preparation by 13.2 pair of oxen‐days per ha. Compared to CP, in general, there is a considerable short‐run maize productivity gain and reduction in labor and draft power use under MTP.
