人民币即期汇率与NDF的关联性：对NDF限制政策的实证研究

检验和揭示境内人民币即期汇率与境外NDF间的互动关系,可为各类市场主体提供有益的市场信息和参考.本文针对2006年10月出台的对境内机构和个人参与境外人民币NDF交易的限制性政策,实证研究了该政策实施后人民币即期汇率与NDF的相互影响.格兰杰因果性检验表明:即期汇率引导12个月期限的NDF;12个月期限的NDF不引导即期汇率.境内现汇市场显现出本土信息优势.在一定程度上说明人民币汇改和限制性措施的成效性,但限制性政策却可能并非长远之计.     

人民币离岸NDF汇率与境内人民币汇率关系的实证

人民币汇改以来,人民币离岸NDF市场的交易日趋活跃,对人民币汇率走势预期的影响也日渐增强.实证结果表明,人民币离岸NDF 市场上存在着不同程度的人民币升值预期,预期升值水平与NDF汇率期限相关;人民币离岸NDF汇率影响着人民币即期汇率,离岸NDF市场对人民币即期市场存在单向波动溢出效应,在信息传递上表现为人民币离岸NDF市场的汇率信息向境内人民币市场传递.     

人民币NDF对境内人民币即期汇率的影响

本文以境外人民币NDF(无本金交割远期)市场和境内人民币即期市场为研究对象,选取2010年8月至2013年11月间1个月、3个月、6个月及1年期人民币NDF汇率和境内即期汇率作为样本数据,通过Granger因果检验分析了两个市场之间的价格引导关系。实证结果表明,境外人民币NDF(无本金交割远期)市场不存在对境内人民币即期市场的价格引导,而境内即期汇率却是人民币NDF汇率变动的先导变量。     

境内人民币远期与NDF汇率关系

对2006年8月11日至2009年11月30日1月期、3月期、6月期和12月期的远期汇率进行统计和计量分析后发现:金融危机后,境内人民币远期汇率与NDF汇率的总体波动性有所降低,人民币远期汇率弹性有所下降;境内人民币远期市场的定价能力提高主要体现在短期限品种NDF汇率对于境内人民币远期汇率单向引导关系减弱,而二者的相互引导关系增强;长期限品种NDF汇率对于境内人民币远期汇率的引导关系不变。因此后金融危机时期一方面要防范国际资本和政治经济压力对中国汇率的冲击,同时也要择机有序退出临时性汇率安排,稳步推进人民币汇率形成机制改革。     

基于人民币NDF汇率与境内即期汇率的实证研究

本文通过对人民币NDF市场汇率与利率平价理论远期汇率的检验证明,前者与境内即期汇率、境内外利率之间存在传导机制。通过对即期汇率与各期限NDF汇率进行协整检验,以及在此基础上对两者进行格兰杰因果检验,分析两者的相互引导关系。结果表明,即期汇率与各期限NDF汇率都存在较为显著的协整关系,并且即期汇率处于信息传导机制中心。     

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。     

人民币汇率定价权问题研究:基于NDF与即期汇率曲实证检验

通过对1999年5月5日-2008年9月1日人民币即期汇率和一年期人民币NDF汇率的研究发现:(1)汇改前,人民币即期汇率本身与人民币NDF没有直接联系,但其变动趋势受NDF影响;(2)汇改后,人民币NDF与人民币即期汇率联系加强,二者的绝对值水平和变动趋势相互影响,互为因果关系。随着人民币NDF对即期汇率影响的加大,人民币汇率定价权问题需引起重视,应加强对人民币NDF的研究,一味地将境内外外汇市场隔绝的政策并非明智之举。     

人民币境外NDF汇率、境内远期汇率与即期汇率的关系的实证研究

2005年7月21日汇率形成机制改革以来,人民币即期汇率波动幅度加大,企业和居民面临的汇率风险加大。在远期市场上,套期保值是规避汇率风险的常用办法。当前经营人民币远期产品的市场主要有两类,一类是境外NDF市场,另一类是境内远期外汇市场,包括银行间远期市场和远期结售汇市场。本文检验了境外NDF市场、境内远期外汇市场和即期外汇市场上人民币汇率的协整关系以及两类远期外汇市场的有效性。对各市场汇率时间序列进行的格兰杰因果检验表明国内远期外汇市场是人民币外汇市场的信息中心。最后,文章对当前的外汇管制政策进行了分析评论。     

国际金融市场动荡和人民币NDF汇率的动态关系分析

随着经济全球化,市场一体化的深入推进,我国金融业与国际市场逐渐形成联动机制,交易的日渐频繁以及国际纵深的不断延伸,我国人民币NDF汇率常常会受到国际金融市场动荡的影响,因此,从实际情况以及相关理论上,我国人民币NDF汇率与国际金融市场的动荡存在一定的动态性关系。基于此,本文通过分析国际金融市场动荡的原因,指出其与人民币NDF汇率的相互关系,进一步分析动态变化的原因,提出完善我国汇率和人民币机制的体制性建议。     

实际股票收益率与通货膨胀率关系的实证研究

股票收益率与通货膨胀率之间的关系至今仍无定论.采用1991年1月到2011年8月的月度数据,运用VAR模型对我国的股票收益率与通货膨胀率之间的关系进行实证分析,结果发现不论是预期的通货膨胀还是非预期的通货膨胀与股票实际收益率都是负相关关系.表明费雪效应在我国不成立,股票并不是对冲通货膨胀风险的理想工具.     

Dynamic Linkages among Budget Deficits,Interest Rates and the Stock Market*

This paper examines the dynamic linkages among the federal budget deficit, interest rates and the stock market for the United States from 1960 to 2006. The empirical strategy includes vector autoregression (VAR) and Granger causality analyses. The results suggest that budget deficits negatively impact upon stock returns, which implies a violation of the Ricardian Equivalence Proposition. Further analysis shows a higher sensitivity of stock returns to corporate taxes than to public spending. Finally, it is shown that although taxes are relevant for corporate profits in the short run, budget deficits are important for the stock market in the long run.     

人民币汇率波动与中国股票价格报酬之间的相关性——基于2005年至2007年的实证分析

本文以2005年7月21日至2007年9月18日的中国股价与人民币兑美元的名义汇率数据,利用GARCH模型来探讨在这段时间内人民币汇率波动对中国股票价格报酬的影响。实证结果得知,在这段时间内人民币兑美元名义汇率波动是负向影响中国股票价格报酬的,也符合有价证券余额理论的主张;汇率市场对股票市场的影响在宏观决策中应予以高度重视。     

特质风险与市场收益动态关系的实证研究

本文使用流通市值加权的股票平均波动率作为股票市场未分散特质风险的间接衡量指标,对A股市场特质风险与市场预期收益之间的动态关系进行研究。有别于国内已有研究,本文使用流通市值加权股票平均波动率的自回归残差项作为回归模型的解释变量,避免了解释变量高度持续性特征给回归结果造成的不利影响,发现A股市场未分散的特质风险对预期市场超额收益具有预测能力,两者呈正相关关系,这种预测能力在考虑市场分割、流动性、经济周期以及不同特质风险度量方法后依然存在。     

The Cross-Section of Stock Returns on The Shanghai Stock Exchange

This study explores the cross-sectional stock return behavior on the A-share market of the Shanghai Stock Exchange (SSE), which is segmented from world's other equity markets. We estimate the effects of beta, firm size, book-to-market equity ratio and a variable unique to the Chinese stock markets, the proportion of firm's floating (tradable) equity over total equity on SSE stocks over the period 1993–2002. We find that smaller firms and value stocks perform better. Systematic risk is negatively significant in down markets. The proportion of floating equity has no direct effect on stock returns.

Asymmetry in Stock Returns Following Block Trades on the Australian Stock Exchange: A Note

A number of recent US. studies have examined the price impact of large (block) trades using intraday data. A major finding is that the price movement following block trades continues upwards following purchases but reverses following sales. This asymmetry in price behaviour, which suggests that block sellers pay a liquidity premium while block buyers do not, has been described as 'intriguing' and a 'key puzzle'. The purpose of this note is to determine whether the phenomenon exists on the Australian Stock Exchange. Evidence consistent with the 'puzzling' asymmetry is shown to exist when returns are measured from the block trade until the close of trade. Contrary to US. findings, which have shown that prices appear to reverse following both block purchases and sales in transaction time analysis, the asymmetry in price behaviour is also demonstrated to exist in transaction returns for the ASX. All results are found to be robust to a number of research design innovations and data partitions.     

Expected Inflation, Interest Rates, and Stock Returns

This paper documents a long-lived asymmetrical relationship between interest rate changes and subsequent stock returns. Drops in interest rates are followed by twelve months of excess stock returns, while increases in interest rates have little effect. The results are robust to the choices of short-term interest rate and stock index. These findings cannot be explained by Geske and Roll's [10] reversed causality argument; nor do they appear to result from periods of unusual interest rates or stock returns. Since interest rate changes are generally used as proxies for changes in expected inflation, the results provide new insights into previous research on inflation and stock returns, and there are important implications for the literature on time-varying risk premia.     

Dynamic Linkages Between the China and International Stock Markets

China has become recognized a fourth world economy and is playing a much more important role than ever before in the world economy. In this paper, we study the relationship between the China and the international main stock markets, including the stock markets in the U.S., the U.K., Japan and Hong Kong. Both long-term and short-term dynamic linkages between the China and the international main stock markets are explored by applying a Markov-Switching Vector Error Correction Model (MS-VECM), which takes into account the three regimes of depression, boom and speculation in the market. Our new findings with the data under study include: (i) There has been a significant trend of long-term co-movement between the China and the international stock markets since 1999. (ii) In short term, the stock market in China has been impacted directly or indirectly by the international main stock markets, which varies under different regimes. This impact is still weak in the depression regime, but strong in the boom regime, and, in particular, it has become very strong through the co-integration error correction in the regime of speculation. These findings are different from those documented in the literature and are potentially interesting for international investment and risk management.
