基于倒"U"型拐点条件对西部大开发的思考

人均收入相对差距和绝对差距的变化是两个既相互联系又有区别的倒U型,出现拐点的条件是欠发达地区人均收入的增长必须超过发达地区.西部大开发以来,人均收入的两种差距均呈扩大趋势,一方面反映了西部大开发的艰巨性和长期性,另一方面对西部大开发的现实和预期目标的实现提出了严峻的挑战.因此,必须加大推进西部大开发的力度.     

我国实施战略性资源保护政策的实效分析

2007年《外商投资产业指导目录》对矿产开发和勘探产业做出不少限制性和禁止性规定,特别是稀有矿产由“限制外商开采”到“禁止外商开采”的改变最为引人注目,标志着中国着手实施战略性资源保护政策。本文在该措施实施的理论依据、实施条件和实证案例进行分析的基础上,为中国实施战略性资源储备和贸易政策以消除“大国贫困化增长”困境提出政策性建议。

Assessing the impact of unilateral trade policies EBA and AGOA on African beneficiaries' exports using matching econometrics

The existing literature studying the impact of non‐reciprocal preferential trade agreements (NRPTAs) assumes implicitly NRPTAs are non‐randomly assigned without showing the evidence of that. Using a matching methodology, this paper investigates whether the “African Growth and Opportunity Act” (AGOA) and the “Everything But Arms” (EBA) unilateral trade concessions have had an impact, and in what magnitude, on the exports of African beneficiary countries in the light of the evidence of the non‐random nature (endogeneity) of NRPTAs. Methodologically, previous studies using the matching procedure focused on bi or multilateral trade agreements. Our work focuses on NRPTAs that depend only on donors' conditions. Accordingly, we show that for NRPTAs, gravity covariates cannot be used for the matching procedure. We propose to use political variables as determinants for obtaining non‐reciprocal trade preferences in order to address the endogenous nature of NRPTA assignment. Our main results confirm that a country becomes eligible for a NRPTA only when it meets certain conditions, defined by their donors, such as political stability and economic regulation (for AGOA), and freedom of expression and human development (for EBA). Results also show that both AGOA and EBA policies have had a positive impact on African beneficiary countries' exports to NRPTA's providers, even if the magnitude impact of EBA is significantly lower than that of AGOA.     

组织变革中互惠性偏好对领导团队协同的影响研究——基于隐性知识转移的视角

团队间管理技能的学习通过隐性知识转移实现,组织变革中管理团队合作效果受文化的制约,直接影响着团队技能的提升,基于互惠性偏好的管理团队隐性知识转移的内在机理是解决这一困境的有效方式。文章分析管理团队隐性知识转移过程,变革过程中互惠性偏好对管理团队隐性知识转移的影响,构建变革过程中互惠性偏好影响管理团队隐性知识转移的基本模型,并对变革管理团队进行现实分析。     

Grassroots innovations in the informal economy: insights from value theory

ABSTRACT

The scholarship on innovation hitherto has prioritized exchange value, scalability and large scale commercialization, overlooking the other significant human centric values discussed in 'value theory'. Consequently, innovations in the informal economy are often undermined due to their inability to generate exchange values. This paper identifies and examines the suitability of the nuanced set of values discussed in value theory for informal sector grassroots innovations. Based on ten years of ethnographic research in different parts of Jammu and Kashmir in India, we find that these innovations generate a diverse set of values, ranging from use value to socially embedded reciprocal exchange value to different forms of relational and non-relational intrinsic values. At a juncture when strengthening alternative innovation approaches occupies a priority, these findings have important bearing on innovation policy scholarship.     

互惠性偏好下的供应链金融委托代理模型比较研究

供应链金融是近年来兴起的用于解决中小企业融资难问题的重要金融创新之一,但目前学术界的研究多以经典的委托代理模型为基准,忽略了供应链金融参与方之间存在着互惠性偏好的倾向。文章简要回顾了委托代理理论的发展脉络,结合行为经济学家Rabin提出的互惠性偏好理论,对委托代理模型进行了行为经济学层面的拓展,以当前流行的供应链金融中核心企业与协作企业委托代理关系为研究对象,比较分析了互惠性偏好引入前后各方的收益情况。文章首先构建了经典的Holmstorm和Milgrom模型,研究了核心企业和协作企业均为理性经济主体情形下的博弈收益情况;其次,通过将互惠性偏好引入到Holmstorm和Milgrom模型中,比较分析了各方收益的变化情况;再次,通过参数校准的方法,进行了具体的数值案例分析;最后对模型未来可能的发展方向进行了展望。研究结果表明：通过引入互惠性偏好,在一定的数学条件下,核心企业和协作企业之间的契约制度设计存在着帕累托改进的空间。
