环境保护的国际合作：以SARS为例

SARS危机反映了当前环境问题日渐国际化的趋势,其根源是资源紧缺和经济全球化之间的矛盾。面对这一问题,各国应通力合作、寻求对策,实现环境保护的国际合作。但环境责任在各国间的分配问题阻碍了国际环境合作的进展。本文指出,基于环境和国力的全球合作机制可合理分配各国的代际责任和代内责任,有利于促进环境保护的国际合作,是一种可行的环境保护国际合作模式。要实现这一目标,首先要各国在代际和代内责任的问题上达成共识,二是要增加国际机构、国际公约对合作各方的约束力。     

我国创业投资的回报率及其影响因素

基于1999年到2003年间我国56个本土创业投资退出项目的数据,本文对我国创业投资退出项目的投资回报率及其影响因素进行了实证研究。结果表明:(1)国有创业投资机构退出项目的平均投资回报率显著低于非国有创业投资机构;(2)创业投资机构的资本规模与回报率呈显著负相关关系;(3)上海、深圳两地创业投资机构退出项目的回报率显著高于其他地区;(4)本土创业投资机构的从业时间、投资规模、投资周期、退出方式均与回报率没有显著相关关系。本文在此基础上提出了相关的政策建议。     

新农村建设:一个政治经济学视角的解析

新农村建设是对城乡经济社会发展不平衡的一个积极回应,它包含经济增长和社会发展两个层面.从政治经济学视角出发,在经济增长方面,户籍、土地、保障等制度性因素制约到农村劳动力的有效流转,从而对劳动生产率提升和农业发展产生负面影响;在社会福利方面,农民的数量优势没有转化为谈判优势,对市场价格和政策制定的影响力较小,其社会福利获取以及发展程度处于不利地位.据此,新农村建设必须对相关制度性、组织性因素进行完善和改革,部分农民的真正流转和留守农民的自发组织将尤其重要.     

论国际经济法的形成发展与知识产权国际保护

国际经济法是国际公法的一个重要组成部分，它经过了三个阶段的形成与发展。特别是自上世纪70年代以来，国际知识产权组织成立，国际知识产权的法律地位日益突出，知识产权的法律保护也就成为各国关注的焦点。如何推动更公平、平等的国际经济新秩序和知识产权法律的完善与发展，是值得研究的新课题。     

Accounting for the business cycle: Nominal rigidities, factor heterogeneity, and Austrian capital theory

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast, the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing. Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings. JEL classification B53, E12, E23, E32     

关于商业银行财务管理创新的探索

本文通过深入探索商业银行财务管理理论,结合近年来我国商业银行财务管理改革的主要进展以及存在的问题,提出推进我国商业银行财务管理创新,从而提升我国银行业在国际上的竞争力。笔者认为,当前财务管理改革的思路是建立一个“以成本效益原则为基础,以信息系统为平台,以预算管理为导向,以内部控制为手段,以业绩评价为依据,通过内外部审计强化监督”的财务管理体系。

Export Composition and Manufacturing Employment in the US during the Economic Downturn of 1991-92

This paper examines the effect that export composition had upon manufacturing employment in the US during the 1991 recession. Although it takes, on average, approximately $66 000 in exports to create one job, the exact gains in terms of total employment depend upon the labour-intensity of the products being exported. Foreign sales by the chemical and textile industries result in a far greater increase in employment than exports by the petroleum refining or steel industries. This analysis estimates the employment effects of manufacturing exports over the 1989-95 period, utilizing an input-output model to capture both direct and indirect effects. The results demonstrate that export composition has, at times, both strengthened and reduced demand for labour. Consequently, if job-creation is a national goal, it may be in the interests of the US to promote exports from sectors that are labour-using.     

Domestic financial market frictions,unrestricted international capital flows,and crises in small open economies

Summary. We present an example of a small open economy where small increases in the world interest rate may induce a sharp decline in output and a precipitous depreciation of the exchange rate. Due to a costly state verification problem in domestic credit markets, combined with unrestricted international capital flows, our economy generates two long-run equilibria, one with low GDP and a relatively depreciated real exchange rate (RER), and one with high GDP and a relatively appreciated RER. The first is always a saddle, while the second may be a sink or a source, depending on the level of the world interest rate. A crisis is identified with the economy switching from an equilibrium path approaching the high-output steady state to the saddlepath approaching the low-output steady state. In Mexicos recent history, periods of growth associated with appreciation of the RER have alternated with periods of sharp contraction and depreciation of the RER. Our economy displays such behavior in response to changes in the world interest rate.Received: 9 April 2002, Revised: 20 March 2003JEL Classification Numbers: E5, F4.G. Antinolfi, E.

浦东新区迁入人口的分异

浦东新区的极化开发形成了区际迁移和省际迁移两股人口迁入流.由于来源地不同,他们在年龄、受教育程度、行职业、收入和居住等方面形成了分异现象,与此同时,也产生了社区重构、社会极化和社会矛盾等问题.劳动力市场分层响应和城市生态位势空间响应是迁入人口分异的主要响应机理.迁入人口的分异问题会影响浦东新区的社会稳定和发展,因此,必须引起足够重视.
