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.     

Distribution Dynamics of CO<Subscript>2</Subscript> Emissions

This paper uses nonparametric methods to examine the convergence in CO₂ emissions per capita on a sample of 100 countries for the period 1966–1996. Industrial countries show a convergence pattern. However, there is little evidence of convergence for the whole sample.     

Environmental Policy in Open Economies and Monopolistic Competition

This paper analyses the implications of international trade for non-cooperative environmental policy in the case of local production externalities. A particular focus is on the potential effects of regulations on the variety of goods and the resulting international spillover caused by trade. A tougher domestic standard negatively affects the utility of the households abroad, since such a policy reduces their variety of imports (due to fewer domestic product inventions) or their consumption of each imported brand (due to higher import prices). Ignoring the negative spillover, non-cooperative governments implement inefficiently strict standards in equilibrium. In contrast to this clear-cut inefficiency result, the impact of international trade on the state of the environment is ambiguous.

解读2005年中国国际收支平衡表

国际收支平衡表不仅综合记载了一国在一定时期内与世界各国的经济往来的情况和在世界经济中的地位及其消长对比情况,而且还集中反映了该国的经济类型和经济结构。2005年,中国的国际收支巨额顺差,具有鲜明特色.透过国际收支平衡表,可以发现中国国际收支的结构特征、问题所在,进而提出改进措施和政策建议。     

我国国际保理法律机制探究

我国办理国际保理的规模尚小。国际保理业务的一些通行做法与我国国内法律环境“不兼容”是影响其发展的关键因素。笔者在探究了由我国《合同法》确立的商事债权让与制度的基础上,分析以此制度作为我国国际保理的法律规范不能完全适应保理实务和国际惯例的要求。其中对未来发生应收账款债权转让的效力、禁转约定的抗辩、隐蔽性保理在我国法律体系下所遭遇的不适及就应收账转让引起的权利冲突等问题,进行了详细的论述,并提出了相应的立法修正原则。     

Multinational firms, international trade and international telecommunications

The study analyses the determinants of international telephone, telex, telegram and leased lines communication between the United States and 46 countries. It focusses on the role of multinational firms, international trading firms and new information technologies within the framework of the theory of transaction costs.Results of the econometric estimates suggest that: (a) technological conditions of telecommunication infrastructure, i.e., international diffusion lags of new information technologies, play an important role in the explanation of international telephone and telex telecommunication flows but not in the demand for telegraph and leased lines, (b) multinational firms use international telecommunication to reduce the coordination costs and are strong customers of leased lines and telephones, but less so of telex and telegrams, (c) international trading firms exhibit less clear preferences in the use of the different media to reduce transaction costs.     

亚洲金融危机之后的深层思考
