汇率制度改革后中国股市与汇市关系——人民币名义汇率与上证综合指数的实证研究

本文利用协整检验和Granger因果检验的计量方法研究了汇率制度改革后中国股市与汇市的关系。实证结果表明,汇率制度改革后中国股市与汇市存在长期稳定的协整关系,人民币升值是中国股市上扬的单向Granger原因。最后,本文利用国际收支和资本流动理论对这些实证结果作了进一步解释,并提出了相应的政策建议。     

中国的股票价格波动及货币政策反应

本文在阐述中国的股票价格波动情况及成因的基础上，分析中国股票价格的信息功能，并对中国的股票价格与各层次货币供应量进行协整和Granger因果检验。结果表明，从总体上看，中国的股票价格在1995年之后，具备一定的信息功能；股票价格与各层次货币供应量之间存在协整、因果关系。由此，货币当局应对股票价格波动做出反应。文章以前瞻性利率规则为基础，运用IS—PC—AP模型，采用GMM法估计出中国包含股票价格因素的货币政策反应函数。     

The response of the Dollar/Yen exchange rate to economic announcements

The paper examines the impact of major U.S. macroeconomic announcements on the Dollar/Yen exchange rate. We find that these announcements are responsible for most intraday and day-of-the-week volatility patterns in this market and we identify the most important announcements. The initial reaction to a major 8:30 announcement begins around 8:30:10 and lasts until about 8:30:50. A partial price correction is normally observed between 8:31 and 8:32. Price movements after 8:32 are basically independent of those observed earlier although volatility continues to be higher than normal until about 8:55.     

汇率与股价：基于世界模型的分析框架

本文从世界模型的角度,阐述世界均衡的特点,初步建立有关汇率和本国股票市场、外国股票市场的函数形式,从而为研究汇率与股价之间的价格互动机制的奠定理论基石。     

汇率与股价：基于上市公司Panel Data的实证分析

对于我国上市公司来说,汇率变动对于股价有着重要的影响。本文在介绍前人已有的研究模型之上,利用上市公司面板数据分析人民币汇率与上市公司股价之间的关系。研究发现：上市公司汇率风险暴露系数变化的方向和大小,不仅与上市公司的性质（进口型还是出口型）有关,而且与上市公司的资产、负债、损益和现金流量密切相关。     

人民币汇率波动与中日贸易

金融危机使人民币汇率存在着较大的不确定性和波动性,对中日贸易产生着重要影响。通过建立中日贸易模型的实证研究,结果表明中国对日出口收入效应较强,从日进口收入效应较弱;对日出口价格效应极强,从日进口价格效应较弱;对日出口汇率波动效应较强,从日进口汇率波动效应不存在。因此,若人民币持续升值,汇率波动日益增强,中国经济将会受到严重冲击。故中国政府应暂缓人民币升值,放缓人民币汇率形成机制改革的步伐。     

人民币汇率预期对经常项下跨境资金流动的影响

本文利用2006-2012年月度时间序列数据．对人民币汇率预期与经常项下跨境资金流动的关系进行了实证研究。结果表明,山东省经常项下跨境资金流动与人民币汇率预期之间存在着协整关系,人民币升值（贬值）预期能够导致跨境资金的大幅流人（流出）。通过对样本企业调查发现．汇率预期在微观角度上影响着跨境资金流动机制的形成。最后,本文对完善人民币汇率预期管理提出了政策建议。     

证券交易所的可竞争性与我国证交所的发展

在技术与制度激变的全球化时代,证券交易所越来越成为了金融业中的竞争实体,21世纪初全球证交所大范围的整合并购,要求我们对于证券交易所的定位与发展应该有新的认识。本文从证交所在市场的中可竞争性出发,探讨我国证券交易所的未来发展。     

送转股对股东财富的影响——基于中国上市公司的证据

以2008、2009年的送转股除权日进行事件研究,通过均值比较与检验方法,首次实证研究我国上市公司送转股后股价变化对股东财富的影响,结果发现:相对于经过调整的除权前一日的股价,2008年股票除权后,股价以高于送转股的比例单调下降;而2009年股票除权后,股价呈上升趋势,并于第14日显著高于经过调整的除权前一日的股价。除权后20天内的股价整体上高于年末股价,说明相对基于年末股价的股利决策,送转股没有降低股价。企业发放股票股利,导致股票总市值上升,增加了股东财富。     

汇率与资产价格互动关系的理论及实证——一个文献综述

本文从汇率与资产价格关系的早期理论及其理论发展入手,通过梳理现有的汇率与资产价格互动关系的国内外理论与证实研究,发现目前仍没有相对成熟的理论来解释汇率与资产价格的互动关系,并就中国的情况解释了这两个变量之间关系割裂的原因。     

人民币名义有效汇率对进口价格的传递效应研究

本文基于一个成本加成模型,实证分析了人民币名义有效汇率对进口价格的传递效应。结果表明,1995年第一季度到2007年第二季度期间,人民币名义有效汇率的进口价格传递是不完全的:汇率若升值1%,短期内进口价格下降约0.26个百分点,长期下降0.25—0.29个百分点。利用滚动回归方法发现1995至2007年期间汇率对进口价格的传递程度呈先下降后上升的趋势。进一步检验表明,人民币名义有效汇率对进口价格的传递一定程度上内生于国内通货膨胀环境,同时也可能和进口产品结构的演变有关。     

The Interaction between Mortgage Financing and Housing Prices in Greece

Although the close empirical relationship between the evolution of mortgage lending and housing prices is well established in the literature, the direction of causation is less clear from a theoretical standpoint. We apply multivariate cointegration techniques in order to address this issue empirically for the Greek economy. Our results, based on a cointegration relationship that we identify as a mortgage loan demand equation, indicate that housing prices do not adjust to disequilibria in the market for housing loans. This suggests that in the long run the causation does not run from mortgage lending to housing prices. In the short run we find evidence of a contemporaneous bi-directional dependence.

Cointegrated Periodically Collapsing Bubbles in the Exchange Rate of “BRICS”

We test the occurrence of periodically recurring rational bubbles in the exchange rate of each of the “BRICS” countries currency relative to the US dollar. The forward exchange rate is used as a proxy for the expected exchange rate, different Purchasing Parity Power (PPP)-based rules for the fundamental exchange rate are considered, and its initial value is endogenously determined. For the chosen model, the regime switching equation satisfactorily fits the data, confirming the presence of rational bubbles for all countries. The dynamics of the exchange rate series for each country is interpreted with the help of the estimated bubbles. The bubbles are compared across countries, found to be cointegrated, and this is interpreted as evidence of the international transmission of exchange rate shocks between these countries.     

The tactical and strategic value of hedge fund strategies: a cointegration approach

This paper analyzes long-term comovements between hedge fund strategies and traditional asset classes using multivariate cointegration methodology. Since cointegrated assets are tied together over the long run, a portfolio consisting of these assets will have lower long-term volatility. Thus, if the presence of cointegration lowers uncertainty, risk-averse investors should prefer assets that are cointegrated. Long-term (passive) investors can benefit from the knowledge of cointegrating relationships, while the built-in error correction mechanism allows active asset managers to anticipate short-run price movements. The empirical results indicate there is a long-run relationship between specific hedge fund strategies and traditional financial assets. Thus, the benefits of different hedge fund strategies are much less than suggested by correlation analysis and portfolio optimization. However, certain strategies combined with specific stock market segments offer portfolio managers adequate diversification potential, especially in the framework of tactical asset allocation.

A common factor analysis for the US and the German stock markets during overlapping trading hours

We employ a bivariate common factor model to establish a permanent-transitory decomposition of two major stock indices (the Deutsche Aktienindex (DAX) for Germany and the Dow Jones Industrial Average (DJIA) for the United States). Using high-frequency data, we (1) identify a common trend shared by both indices, (2) find that the DJIA contributes up to 95% to the total innovation of the common factor, (3) show that both markets adjust within minutes to a system-wide shock, and (4) verify by hypothesis testing that the DJIA is the driving force in the transatlantic system of stock indices.     

汇率变动对我国物价水平不完全传递的原因分析

人民币的升值并没有成为控制物价上涨的主要经济手段,这种现象与理论不符。本文通过国内外学者关于汇率变动对于物价水平不完全传递原因的总结归纳,结合我国实际的经济状态,总结了汇率变动对于物价水平不完全传递的基本原因并进行分析,分析得出,我们应该适时适量地增强汇率弹性,这样就会在很大程度上改善政策调节物价水平的有效性;另外,我们应采取鼓励进口等措施,这样在很大程度上改善对物价的控制水平;目前,我国经济市场上仍以政策经济为主,政府只有全面地利用各种政策,做到及时得进行调节,才能保证各个政策相互促进地发挥积极的作用,达到理想的政策目标。     

货币政策应该关注资产价格和汇率吗?

在Rudebusch and Svensson(1999)模型中引入了房地产价格、股票价格和汇率因素,以此为基础推导出最优货币政策反应函数。该反应函数显示,中央银行既要应对产出和通货膨胀变化,还应该考虑资产价格和汇率波动。基于GMM方法的实证分析表明,该反应函数能够较好刻画过去10多年间中国中央银行的货币政策。总体而言,该反应函数可以作为中国货币政策制定和执行的参考框架,货币政策应该对资产价格和汇率波动给予一定程度的关注。     

全球化、资产价格变动与中国货币政策反应——基于泰勒规则的扩展研究

在经济全球化、虚拟化的背景下对泰勒规则进行了扩展研究,分析了利率与汇率、利率与资产价格的相关影响机制;并采用静态模型和基于预期的动态模型对名义利率与通货膨胀水平、产出缺口、汇率、股票价格缺口以及房地产价格缺口之间的关系进行了检验。结果显示,考虑预期因素的动态模型能够达到稳定通货膨胀的作用,短期名义利率对于汇率和资产价格起到了符合经济意义的稳定作用。
