浙江农民工流失与财政对策研究——以农民工廉租房为突破口

农民工是浙江经济发展的主要劳动力,农民工流失将成为浙江经济持续发展的瓶颈。本文通过分析得出在浙江刘易斯拐点已经显现,未来浙江籍农民工数量将大幅度减少,外地农民工返乡危机潜在,进而提出以农民工廉租房为突破口等财税对策,留住农民工。     

基于数值模拟下的中国外汇储备潜在损失分析

外汇储备余额持续积累加剧了外汇储备资产潜在损失的进一步扩大。文章通过对中国外汇储备积累方式的分析,认为造成外汇储备损失的主要路径有三个:冲销债券的利息支付、国际短期资本的投机和人民币对美元汇率升值。在此基础上,文章数值模拟了不同路径下的外汇储备潜在损失,得出以下结论:一是人民币过快升值会加重我国外汇储备损失,应根据我国金融市场的发展状况,逐步改革汇率体系,令人民币更富弹性;二是改变中国外汇储备管理模式,从以往的被动型、防御型模式变成主动型、投资型模式,一方面逐步放松资本账户管制,允许个人和机构海外投资,另一方面加大中国的主权财富基金——中国投资公司的投资力度和规模,通过市场化手段获得更高收益。

Temporal and spatial variability of agricultural land loss in relation to policy and accessibility in a low hilly region of southeast China

The temporal and spatial patterns in land use change in a low hilly region in southeast of China was analyzed from maps of converted agricultural land for 1999–2006. The factors driving farm land conversion was analyzed using logistic regression models. The amount of agricultural land loss varied temporally, and the spatial distribution of converted agricultural land patches decreased from low to high altitudes in the study area. Analysis using logistic regression models showed that good accessibility sped up the conversion of agricultural land to other uses, the elevation of a parcel lowered the risk of conversion, and agricultural land conversions are highly correlated with its adjacent or neighboring parcels’ land use, with the probability of being converted decreasing as the distance to nearest construction land increases. In addition, land use policy, especially the land use regulation policy issued by the central government decreased the agricultural land loss, and the more stringent regulation on cultivated land conversion lowered the possibility of conversion from cultivated land to other use.     

Career Risk

The author defines asset manager career risk as the risk that asset owners terminate an existing manager due to an extended period of underperformance relative to a benchmark or peer group even though the manager has skill (defined here as positive information ratio). The author shows that myopic loss aversion gives rise to career risk even for skilled asset managers and that the current industry practice of quarterly or annual performance evaluations puts even the most skilled asset managers at risk of undue termination. The author also investigates how a reduction of tracking error leads to a reduction of career risk even though this comes at the expense of lower long-term performance. Finally, the author computes the minimum evaluation period needed to reduce career risk for asset managers of different skill levels.     

Review: Food loss and waste in Sub-Saharan Africa

The research, development practitioner, and donor community has begun to focus on food loss and waste – often referred to as post-harvest losses (PHL) – in Sub-Saharan Africa. This article reviews the current state of the literature on PHL mitigation. First, we identify explicitly the varied objectives underlying efforts to reduce PHL levels. Second, we summarize the estimated magnitudes of losses, evaluate the methodologies used to generate those estimates, and explore the dearth of thoughtful assessment around “optimal” PHL levels. Third, we synthesize and critique the impact evaluation literature around on-farm and off-farm interventions expected to deliver PHL reduction. Fourth, we suggest a suite of other approaches to advancing these same objectives, some of which may prove more cost-effective. Finally, we conclude with a summary of main points.     

习语翻译中的关联缺失与关联重建
