Perpetual youth and endogenous labor supply: A problem and a possible solution

In the “perpetual youth” overlapping-generations model of Blanchard and Yaari, if leisure is a “normal” good then some agents will have negative labor supply. We suggest a solution to this problem by using a modified version of Greenwood, Hercowitz and Huffman’s utility function. The modification incorporates real money balances, so that the model may be used to analyze monetary as well as fiscal policy. In a Walrasian version of the economy, we show that increased government debt and increased government spending raise the interest rate and lower output, while an open-market operation to increase the money supply lowers the interest rate and raises output.     

论保单持有人最后一道安全屏障:保险保障基金

保险公司退出市场的形式一般分为解散、撤消、破产等。从经济角度来看，保险公司退出的核心问题是保险公司的破产。出于保险公司的经营涉及到多方面的利益，如果简单允许保险公司破产，必然影响整个金融体系的稳定和社会经济的正常发展。因而，在引入竞争机制的同时，还必须建立科学的保险保障基金制度。     

货币政策的粘性均衡汇率效应模型及人民币汇率定价的弹性分析

本文以开放的宏观经济为框架、以厂商利润最大化为微观经济基础、以严格的数学推导为逻辑纽带、以粘性价格为理论依据、以购买力平价的微分冲击形式为理论基础，提出并构建了两国货币政策的粘性均衡汇率效应模型。应用模型，本文对1992～2002年的人民币粘性均衡汇率进行了定价，并对2003年的定价进行了预测。以定价汇率及其预测为标准，对1992～2003年的人民币汇率偏离与经常性项目的关系，进行了弹性分析。根据模型与实证分析，获得了一些重要结论。     

Pure joint production and international trade: a note

This paper applies the principles of the neo-Ricardian (or Sraffian)theory of international trade to certain joint production systems.It is shown that, in contrast with single-product systems, (i)there is not always a pattern of international specialisation,which would entail the increase of the real wage rate in botheconomies, and (ii) the ‘law of comparative advantage’has no general validity. Furthermore, not only the existenceof such a pattern of specialisation but also the validity ofthis law depend on the values of the variables of distributionof income. The analysis is wholly based on two of the numericalexamples formulated by Bidard in 1997, and further generalisedin an elementary way only when this is considered necessary.     

我国货币政策的透明度及效应分析

本文在评估了目前我国货币政策透明度现状的基础上，分析了提高透明度所产生的正效应，同时也指出我国央行透明度的制度建设还根不完善，尤其是决策透明度较低，产生了一些负效应，影响了政策的执行效果，最后提出了进一步提高透明度的建议。     

Organising international supplier relations: An exploratory study of Western purchasing in China

This paper analyses Western purchasing in China in order to investigate the motives for sourcing, the specific requirements of the area and, in particular, the base and features of supplier relationships. It reports recent experiences of seven companies based in Finland, including two global companies, two units with foreign ownership and three Finnish SMEs. Prevalent in Chinese sourcing are long-term supplier relations, but no partnership relations have been established. The companies build their supplier relations gradually and they all emphasise a long-term viewpoint to Chinese sourcing. Commitment of the Chinese partner is a key challenge, overcoming of which would help companies to avoid and solve, e.g. quality problems. The study shows that, for the Western supply personnel, key competences and tools for bridging the psychic distance are social skills and interest in the Chinese culture.     

国际证券市场联动程度的实证分析

20世纪80年代以来,通过国际证券投资分散风险已经形成一种可行手段,然而,随着全球经济一体化趋势的强化,国际证券市场也正在经历着一体化趋势,证券市场联动关系越来越明显,这必然会使国际投资多样化空间变小,进而会侵蚀掉国际多样化投资收益.有鉴于此,本文使用协相关参数分析、平稳性检验、多元协整检验、协整向量参数零配载限制检验、基于VECM的Granger因果性检验等计量技术测度国际证券市场联动程度,为国际证券投资提供量化参考.     

环境成本内部化及其对国际贸易的影响

当前,许多国家加强了对环境的管制,加快了环境成本内部化的进程。本文阐述了环境成本内部化的涵义,对其效应做了理论分析,并分别论述了其对国际贸易理论和实践两个方面的影响。     

论我国会计国际化的模式选择

随着经济全球化浪潮的掀起,作为商业语言的会计同样面临着国际化的抉择。本文针对目前我国会计国际化的不同观点,在对我国会计准则与国际财务报告准则之间差异进行比较、分析的基础上,以会计信息使用者及其需求为出发点,提出了我国会计国际化的模式选择。     

温和通货膨胀下的货币政策选择

2003年以来,我国摆脱了通货紧缩的阴影,进入了一个温和的通货膨胀时期.这一轮温和的通货膨胀主要源于货币信贷的过快增长,而基础货币投放过多主要源于外汇占款的快速增长.实证研究表明,我国通货膨胀率与M0、M1、M2以及贷款增长率之间都存在正相关关系.缓解和释放通货膨胀压力既需要运用数量型货币政策工具,更需要运用价格型货币政策工具.为了缓解通货膨胀压力,中国人民银行应该实行"双升"的货币政策,在调升人民币利率水平的同时调整人民币汇率,既升息又升值,但升息和升值的幅度不宜过大.
