Regulatory ‘Balancing’ and the Efficiency of Green R&D

We identify and analyse several dynamic implications of setting environmental standards such as to balance marginal costs and benefits. The adoption of such a regulatory approach is shown to effect (i) the speed of improvement of abatement technologies; (ii) the direction (in a sense to be defined) of that improvement; (iii) its source and the distribution of the rents from it; and (iv) the rate of development of defensive (averting) technologies. Existing views are thoroughly synthesised in the context of a simple diagrammatic model, several new results are derived and at least one conventional wisdom questioned. The message of the analysis for legislators and regulators is that cost–benefit balancing should be done with care.     

我国县域经济发展的环境影响分析

文章回顾了近年来区域经济发展与环境关系的相关研究成果，定义了环境友好度的概念，运用层次分析法，结合我国生态县有关指标，构建了县域环境友好度的分析模型，以S县为例，计算出环境友好度的具体数值，为该县评估自身经济发展与环境之间的关系提供了依据。县域环境友好度分析模型为我国其他县评估自身经济发展与环境之间的关系，提供了一种定量的分析方法。     

A model of the origins of basic property rights

This paper studies the origins of one of the most basic of property rights, namely, the right of an individual or an organization to the fruits of its labour. My objective is to address the questions of why, when and how this property right can emerge and be made secure. I develop a model of the strategic interaction between two players in the state-of-nature, which is an environment characterized by the absence of any laws and institutions (including property rights and the state). My analysis explores, in particular, the roles of the players' fighting and productive skills on the emergence and security (or otherwise) of this property right.     

控股股东、实际控制权与小股东权益保护

股权集中型公司是现代公司的主流组织形态之一,其代理成本主要产生于控股股东与小股东之间存在的利益冲突.通过发行多种类股票、交叉持股和金字塔式控股等方式,控股股东能够获取比与其股权份额相对应的名义控制权更大的实际控制权,因而更容易发生以侵害小股东权益作代价追求控制权私下收益的道德风险行为,致使代理成本高昂.声誉机制和法律手段能够迫使控股股东收敛侵占行为,且法律手段较声誉机制更为有效.在中国,声誉机制对控股股东基本不起作用,保护小股东权益的最为有效的措施是完善相关立法并加大执法力度.     

环境意识的内涵及其作用

环境意识的概念是随着人与自然的矛盾加剧而产生的。环境意识反映的是人们的一种心理,是对环境的认同感。在这种心理的作用下,人们会有意识地去关注环境变化和生态平衡,并且会自觉地维护生态系统的良性发展。环境意识包括环境认识观、环境价值观、环境伦理观、环境法制观和环境参与观五部分,分为感性认识、知识、态度、评价和行为五个层次。对环境意识的研究在人与自然的发展中具有巨大的实践指导意义。     

Leaving EMU: a real options perspective

The real option implicit in a country's decision of whether to leave an existing monetary union when there is uncertainty over the future benefits of this move is examined. The theoretical model used is calibrated for the current Euro-12 area by proxying policymakers’ inflation preferences with unemployment rates and debt-to-GDP ratios. A robust group of countries is observed that would choose to remain within EMU consisting of Belgium, Finland, Greece and Italy; France and Spain loosely also belong to this core. Only Luxembourg would robustly want to leave EMU; Ireland and The Netherlands, however, complement that core closely.     

环境所有权、贸易结构变迁与污染分布——基于超边际经济学框架的分析

文章引入环境所有权概念,运用新兴古典经济学的超边际分析方法,研究了贸易结构变迁与相应的污染分布和转移,旨在揭示大国污染效应、工业化路径的环境效应、贸易结构变迁的环境所有权因素以及环保政策失效的原因。研究推导出不同国家间环境所有权模糊程度和交易效率变化对贸易结构变迁与污染分布变化的作用机理。研究命题可用于解释现实贸易发展中存在的环境污染现象。
