金融危机正在改变世界

当前金融危机是经济周期的必然结果，其直接原因是以美元为核心的单体国际货币体系和保护主义日益严重导致的全球经济的长期失衡，要通过这场金融危机来平衡全球金融体系和经济的关系。因此，建立多元的国际货币体系，是这次金融危机之后最重大的金融制度的变革。目前金融还是现代经济的核心和心脏，不能因为金融危机而停止中国金融的市场化改革的步伐；同时，金融危机给中国带来了两个难得的机遇，即人民币的国际化和全球金融中心的构建。     

Conditions for Optimality of a Currency Area

Two approaches to the theory of OCA are distinguished in this paper. The first, called the marginalistic approach, attempts to define the OCA from the point of view of a single country, and the second examines the optimality of a currency area of a given membership. The marginalistic approach and its limitations are discussed first. Then, the paper proceeds to the second approach which is discussed in the context of the cooperative game theory in characteristic function form; it argues that a currency area is optimal when the welfare functions of its constituent members are in the core. This implies that the welfare functions of all constituent members of the currency area are maximized and hence they are all better off with a common currency rather than with their own national currencies; hence, no member country has the intention to abandon the currency area. The paper concludes that the condition for the optimality of a currency area independently of the degree of economic similarity of its constituents requires that the characteristic function must exhibit non decreasing returns with respect to its size.

A Model Forecasting Risk for Emerging Market Currencies

In this paper, we propose a risk forecasting model for emerging market currencies. Our model is based on the Markov regime switch which is constructed by exploiting daily equity market information, and we show that our model outperforms the existing model using macroeconomic information. We evaluate it by the performance measures, the goodness-of-fit and the Wilcoxon rank-sum test.     

本币升值对股市的影响——基于日本的经验研究

作为一国经济晴雨表的股票市场，不可避免地受到汇率变动的影响。文章以日本为例，分析本币升值对股市的影响。分析表明，本币升值在短期内推动本国股市繁荣，往往伴生股市泡沫，但继续升值预期一旦消失，股市往往出现大幅度下跌。因此，在人民币持续升值的背景下，必须根据我国的实际情况慎重考虑其对股市的影响。     

How does a devaluation affect the current account?

This paper explores how an exchange rate devaluation affects the current account in a sticky-price inter-temporal optimizing model. The main issue addressed is how the features of international pricing affect the response of the current account. When prices are all set in the producer's currencies, the effect of a devaluation on the current account depends on the conventional Marshall–Lerner conditions. This is fundamentally an a-temporal condition (depending on the elasticity of substitution between home and foreign goods). However, when prices are all set in consumer's currencies, the response of the current account depends upon the size of the inter-temporal elasticity of substitution of consumption across time periods. This represents an inter-temporal condition. When pricing-to-market is partial, the effect of devaluation on the current account depends on the strength of the a-temporal elasticity relative to the inter-temporal elasticity.     

货币国际化与非国际化选择——韩国、新加坡实践比较

20世纪70年代布雷顿森林体系崩溃之后,以美元为中心的国际货币体系发生了变化,储备货币呈现了多元化的趋势。东亚的一些发展中国家也开始了本国货币国际化的实践。货币国际化的实现可以带来很多好处,许多学者对如何成为国际化货币给出了理论解释。文章分析了韩国、新加坡两国对实现货币国际化的不同态度,从而对人民币国际化提出了政策建议。     

欧元区统一货币政策绩效及其对中国的启示

欧元产生以来,欧洲中央银行在统一货币政策的框架下较好的实现了物价稳定的首要任务,却未能有效促进欧元区的经济增长、充分就业和国际收支平衡,主要原因在于:成员国经济基本面的差异使统一货币政策产生了巴拉萨-萨缪尔森效应。由此给当前正致力于货币合作的东亚地区带来了一个重要启示:应不断加强各国间的政策协调,确保主要经济指标高度趋同,为将来单一货币的实行奠定重要基础。     

我国通货膨胀过程的社会福利成本度量与经验分析

通过利用1994年至2006年之间的我国GDP、M1和名义利率的季度数据,采用协整检验和回归系数估计方法,获得我国长期货币需求函数,在此基础上对我国通货膨胀的社会福利成本进行了实证分析。实证结果表明,我国较高的通货膨胀率会带来比较大的福利成本,因此,当前通胀压力较大的时期,采取适当的宏观调控措施,将通货膨胀率控制在3%以下的低水平状态。
