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。     

境外人民币NDF和境内人民币掉期之间关系的实证研究

我国2005年7月21日启动人民币汇率形成机制改革以来,人民币汇率波动性显著放大,各经济主体运用人民币远期产品规避汇率风险的需求增加。本文运用协整检验、Granger因果关系检验、ECM模型和脉冲响应函数,运用交易比价活跃的5个期限的人民币远期产品对境外人民币NDF隐含掉期点数和境内人民币市场掉期点数之间的关系进行了实证分析并对其作用机制进行了讨论。结果表明,在各个期限的远期产品上,境外NDF隐含掉期点数和境内人民币掉期点数之间存在长期正向的协整关系,其中NDF处于主导地位。     

人民币远期汇率定价实证分析

人民币远期结售汇是我国较早发展的最常用的规避汇率风险的产品之一。本文运用协整检验和格兰杰因果检验方法,对境内人民币远期定价的抵补和非抵补利率平价条件以及境内外远期汇率长期均衡关系和信息传导机制进行了实证分析。实证分析结果表明,利率平价条件在境内人民币远期汇率定价中起到基础性作用,受一些限制因素影响,汇率预期的非抵补利率平价条件不成立,远期汇率水平不能作为未来即期汇率的预期变量,境内外远期汇率存在一定的长期均衡关系,境内远期汇率对境外汇率有相对明显的引导作用,境外远期汇率的非理性人民币升值预期,也对境内远期汇率定价存在影响。     

境内外人民币远期汇率的关联性分析

随着我国经济对外开放程度的提高，人民币汇率对世界经济的影响也渐次增大，境外机构和个人亟需利用人民币远期汇率对冲人民币汇率风险。然而由于我国实行外汇管制，境外机构不能进入境内外汇市场，于是新加坡在1996年开设了人民币兑美元的无本金交割远期（non-deliverable forward，NDF）市场。随着该市场的迅速发展，NDF汇率与我国境内人民币兑美元远期汇率的关联越益紧密，值得引起我们的高度关注。     

香港和境内人民币远期汇率的溢出效应研究

本文运用平稳性检验、格兰杰因果检验等计量经济学方法,对香港人民币无本金交割远期汇率(NDF)与境内人民币远期汇率之间的报酬溢出效应进行实证分析。研究发现:香港人民币NDF汇率对境内人民币远期汇率存在单向的报酬溢出效应,而不存在反向传导关系。根据研究结论,作者建议我国要进一步增强人民币汇率弹性、完善汇率形成机制,促进市场竞争和提高远期市场定价的效率。     

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。     

人民币汇率预期：基于ARCH族模型的实证分析

人民币汇率升值预期持续强化,观察其变化的重要指标主要是境外人民币无本金交割远期汇率(CNYNDF)。本文建立CNYNDF的高频日汇率随机游走模型,运用ARCH族模型检验该模型的残差后发现,其时间序列数据具有"尖峰厚尾性"和集群性特征。在信息不对称的条件下,市场对人民币升值和贬值存在不同程度的反应,2002年以来,市场预期人民币升值,市场信息具有杠杆作用。2005年7月21日人民币汇率形成机制改革以来,境内人民币即期汇率和远期汇率开始受CNYNDF报价引导,逐步形成稳定的Granger因果关系。为取得人民币汇率定价的主动权,中国需加快外汇交易的微观制度建设,加强汇率与利率改革的协调性,为规避汇率风险创造市场条件。     

人民币远期汇率无偏性的动态检验北大核心CSSCISSCI

本文运用带有结构断点的ZA平稳性检验和滚动协整检验方法,对2005年7月到2016年5月境内外四种不同期限的人民币远期汇率和即期汇率进行分析,动态地考察人民币对美元远期汇率对未来汇率的预测是否具有无偏性。带有结构断点的平稳性检验表明,NDF不同期限的远期汇率和即期汇率的差值序列是平稳的,人民币远期汇率满足无偏性的必要条件。而滚动协整检验表明,除1个月期远期汇率和即期汇率之间存在稳定的协整关系,其他期限之间并不存在持续的协整关系,且协整系数在大部分时间内显著异于1。另外,境外NDF汇率无偏性的表现在各方面要强于境内银行间外汇市场远期汇率;随着人民币汇率市场化程度的逐步加深,远期汇率的无偏性表现并没有显著提升。     

研图观势

2011年9月中下旬以来,境外内市场人民币汇率出现倒挂（见图1）。2005年7月人民币汇率形成机制改革,由于强劲的单边升值预期,在香港美元兑人民币要比国内便宜。到2011年9月中下旬,这种状况突然逆转,香港市场上美元变得比境内贵,人民币反而更便宜。在9月底1O月初欧洲危机高潮之际,境外美元现汇一度比境内高出1500个点左右,无本金交割的远期外汇交易美元也由贴水转为升水。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

Cost accounting standard and cost accounting systems in Japan. Lessons from the past - recovering lost traditions

This paper aims to show two things. The first is how Japanese culture has contributed to the development of Japanese cost accounting history. The second is to reveal the research possibilities of cost accounting history. This paper also reviews the salient features of several important examples of these aspects of cost accounting practice in Japan. It therefore explores, through some practical illustrations, how and why Japanese cost accounting differs from that found in the West.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia. The paper also attempts to explain the gap of thirty-two years between the formation of the first accounting bodies in Edinburgh and Melbourne.

Shared Standard Setting in the Public Interest:A Strong Model

正The last two decades have been a definitive era in the evolution of the accountancy profession.In the wake of major corporate scandals at the turn of the century,an international public debate arose on the need for more effective and well-considered regulation;this debate then reignited during the global financial and sovereign debt crises.
