International Trade and the Environment: Theoretical and Policy Linkages

I review and extend three approaches to trade and environmental policies: competitive general equilibrium, oligopoly and monopolistic competition. The first two have surprisingly similar implications: deviations from first-best rules are justified only by constraints on policy choice (which motivates what I call a “single dividend” approach to environmental policy), and taxes and emissions standards differ in ways which reflect the Le Chatelier principle. I also show how environmental taxes may lead to a catastrophic relocation of industry in the presence of agglomeration effects, although not necessarily if there is a continuum of industries which differ in pollution intensity. *An earlier version was presented as an invited plenary lecture to the European Association for Environmental and Resource Economics Conference, Oslo, 1999.     

基于生命周期的虚拟企业知识活动分析及其伙伴选择过程研究

随着新经济的到来,知识越来越成为企业快速响应市场机遇和获取竞争优势的最短缺资源.而企业自身知识资源的有限性使企业越来越多地采用虚拟企业的高级形态--知识联盟型虚拟企业来弥补企业知识资源的不足以快速响应变化的市场需求.本文首先对知识联盟型虚拟企业的知识缺口类型进行研究和划分,然后分析并描述虚拟企业生命周期各阶段的知识活动;在此基础之上,探讨虚拟企业组建阶段考虑知识要素的伙伴选择过程;最后,针对不同的知识缺口,提出伙伴选择过程的评价指标体系设计中应考虑的知识性因素.

GAME THEORETIC MODELS OF MIXED OLIGOPOLY

Abstract. In this paper we review various models that have been proposed for the study of mixed oligopoly, that is markets in which private and public firm compete on equal basis using only market instruments.     

Does support from government help firms survive? Evidence on financial and political assistance in China, 1998–2007

ABSTRACT

Using the National Bureau of Statistics data set over the period 1998–2007, this article examines the dual roles of financial assistance and strong political links on firm survival in China by applying a semi-parametric duration model. We find that generally either financial assistance or strong political links had a positive effect on the likelihood of firm survival. Furthermore, if firms received both types of support from government, their survival rate was around two times as high compared to only receiving a single support. The likelihood of survival depended on the amount of assistance a firm received. We also find firm ownership impacts on its survival pattern. Lastly, China joining the World Trade Organisation (WTO) coincided with (cet. par.) higher firm failure, especially with regard to state-owned firms; however, this period also saw the authorities targeting political and financial help on the ‘better’ firms (especially SOEs) with characteristics likely to increase their chance of survival.     

家族式治理对公司理财行为的影响机制研究

家族企业已经越来越受到人们的重视。在现有文献的基础上,论文以所有权和控制权为两维对家族企业做了严格的定义和划分,并把研究对象界定在拥有高控制权的家族式企业。通过将家族式治理和公司理财分析范式结合分析,家族式治理中的网络式组织结构、封闭式的股权结构和作为家族意愿体现的董事会治理机制对家族企业理财行为产生影响。家族式治理对公司理财行为产生正面影响,但由于其自身的局限性和家族企业所处环境的变化,家族式理财必须进行变革:非家族化的理财方式变革,家族规则与现代市场游戏规则的融合,引入有效专家理财制度,以及对家族式理财的扬弃。     

企业同质性假设、异质性假设与企业性质

本文通过对企业同质性假设和异质性假设的进一步探讨,认为运用企业同质性假设的抽象方法可以合乎逻辑的解释企业的契约本质和企业契约的"规制或分配性",而企业异质性假设方法的运用可以理解企业的多样性和差异性,从而对企业契约的"生产性"做出令人信服的解释.企业契约理论和企业能力理论在事实上共同构成了一个有关企业性质认识的完整分析框架.
