证券交易机制影响股价吗?——对中国股票市场的再检验

本文在对分别按照开盘价和收盘价计算的两种收益率的比较中发现了极值聚集现象 ,文中将形成这一现象的原因归结于市场中涨跌幅限制的存在 ,并建立了一个简单模型对此进行了说明。其后 ,利用市场中不存在涨跌幅限制时期的数据对该模型进行了验证。在结论部分 ,本文分析了除交易机制外造成两种收益率差异的其他因素 ,并认为有关交易机制对股价行为影响的研究有待深入。     

Foreign-currency transactions and the recovery of German industry in the aftermath of the First World War: the case of Schering AG

While historians have for a long time recognized the importance of the First World War to the general flow of history, business economists do not fully appreciate the impact of the war on commercial relationships. The First World War transformed the political, economic, and social context, in which business was done, forcing companies to develop new strategies and activities, some of which were almost unimaginable before August 1914. This article focuses on one aspect of doing business: foreign exchange management. It argues that Schering AG and its parent, like many German companies after the First World War, were obliged to refocus their activities around their foreign exchange exposures and that the management of foreign exchange issues contributed to a much tighter relationship between businesses, government, and business associations than had existed before the war and for which some aspects of Germany's system of corporate control were not well adapted to handle.     

我国固定资产投资宏观效益分析

固定资产投资的直接目的是增加固定资产 ,应考察投资和增加固定资产的关系 ,其宏观指标为固定资产交付使用率和项目建成投产率 ;固定资产投资的最终目的是促进经济增长 ,增加国民收入 ,应考察投资和增加国民收入的关系 ,其宏观指标为固定资产投资效益系数或投资系数。我国固定资产交付使用率“七五”时期比“六五”末不断提高 ,“八五”较为平稳 ,“九五”开始回升。我国固定资产投资效益系数“六五”以来较为平稳 ,“八五”较高 ,“九五”下滑幅度较大。应采取多种措施 ,不断提高投资效益。     

积极财政政策的可持续性分析

本文分别从当前宏观经济形势、我国政府债务风险和公共部门投资的挤出效应三个方面考察了我国积极财政政策的可持续性。认为我国当前的经济形势下 ,积极财政政策的淡出还为时尚早 ;我国单纯的国债风险并不高 ,但是我国政府的综合债务风险却相当大 ,控制我国综合债务风险的关键是控制存量 ;我国公共部门对民间投资的挤出效应不明显 ,当前民间投资不活跃的主要原因是另一种“挤出效应” ,即对民间投资的歧视和限制 ,要改变这种情况的主要方法是改革     

Central bank interventions and jumps in double long memory models of daily exchange rates

In this paper, we estimate ARFIMA–FIGARCH models for the major exchange rates (against the US dollar) which have been subject to direct central bank interventions in the last decades. We show that the normality assumption is not adequate due to the occurrence of volatility outliers and its rejection is related to these interventions. Consequently, we rely on a normal mixture distribution that allows for endogenously determined jumps in the process governing the exchange rate dynamics. This distribution performs rather well and is found to be important for the estimation of the persistence of volatility shocks. Introducing a time-varying jump probability associated to central bank interventions, we find that the central bank interventions, conducted in either a coordinated or unilateral way, induce a jump in the process and tend to increase exchange rate volatility.     

Money and exchange rates in the Grossman-Weiss-Rotemberg model

We analyze the impact of monetary policy on inflation, interest rates and exchange rates in a model with segmented asset markets developed by Grossman and Weiss (1983) and Rotemberg (1984, 1985). We find parameters for which real and nominal exchange rates in this model are (1) much more volatile than interest rates, inflation rates, and money growth rates, (2) highly correlated with each other, and (3) highly persistent. While this model fails to match the data in other important respects, it illustrates a potentially useful approach to modelling exchange rate behavior.     

汇率制度、资本流动与金融危机:理论和实证分析——东亚金融危机视角

20世纪90年代,几乎所有发生金融危机的国家当时都实行固定或钉住汇率制度。东亚金融危机爆发前,东亚各经济体大多实行钉住美元的相对固定汇率制,大量国际资本流入,本币严重高估,经常项目巨额逆差,宏观经济严重失衡。在汇率贬值的预期下,国际投机资本对东亚经济体货币发动攻击,大量资本流出,受攻击的经济体外汇储备耗尽,最终导致实际钉住美元的固定汇率制崩溃,金融危机爆发,蔓延成危及东亚乃至世界的金融危机。东亚金融危机的事实表明,金融危机、资本流动和汇率制度之间存在着密切关系。     

我国涉外企业外汇交易风险研究

随着世界经济逐步向全球一体化的方向发展以及我国对WTO相关条款的逐步履行,我国与其他国家的经济往来也变得更加频繁。更为重要的是,我国外汇管理体制改革的进一步深化和外汇市场的发展和完善,使得人民币汇率开始走向市场,汇率变动的频率和范围将大大增强。因此,在这一背景下,本文以科学性和前瞻性为指导原则,通过阐述我国涉外企业面临的外汇交易风险现状和问题,揭示这类企业加强外汇交易风险管理的必要性,在此基础上,来探讨外汇交易风险对我国涉外企业净利润的影响,最终结合我国外汇管理体制改革的实践,提出有效防范和规避外汇交易风险的建议和对策。     

On the distributional effects of exchange rate fluctuations

How do exchange rate movements affect different sectors of an economy? We address this question in a simple general equilibrium model, stressing the different exposures of various sectors to foreign competition, an aspect ignored in earlier contributions. The impact of exchange rate shifts is highly heterogenous across sectors. While a depreciation leads to a substantial competitiveness and welfare gain for agents with a high exposure to foreign competition, agents facing mostly domestic competition are adversely affected.
