汇率是一种货币用另一种货币表示的价格,是一国货币与他国货币的兑换比率,汇率变动影响本国产品在进口国的贵贱,影响本国进出口和国际收支的平衡,影响本国经济和金融的安全,理论汇率决定于两国货币价格量之比,实际汇率决定于外汇市场的供求,国际收支是影响汇率的主要因素,国际收支发生顺差,表明本币供不应求,一般会引起本币汇率上升,本国利率高于另一国利率,引起短期资金流向本国,一般导致本国货币汇率上升,本国通货膨胀率上升,本币汇率一般下降,汇率变动还受到各国中央银行的干预、市场预期心理、投机资本和政治与突发性因素的影响。 相似文献

英国经济学家信息中心(EIU)的分析员日前表示,亚洲经济增长将有助于降低美国经济增长放缓对全球的不利影响。该机构的网络主管麦克斯顿说:“美国经济步入衰退的可能性在增加,但是对于全球经济来说,亚洲经济应该起到缓冲作用。”据马来西亚媒体报道,EIU预测美国经济增长明年将从 相似文献

2006年2月6日上午9点,在美国总统布什的捧场下,美联储的新任掌门人本·伯南京正式宣誓就职。颇具戏剧性的是,在五六年前,本·伯南克在《华尔街日报》上曾撰文提过这样一个问题:“当格林斯潘离去,一切将会怎样?” 相似文献

众所周知,2006年1月31日,曾陪伴六任美国总统18年的美联储掌门人格林斯潘即将卸任,因格林斯潘在任期间常把美元调息放在25%(1/4)的幅度以内,所以美国民众幽默地把格林斯潘戏称为“阔特尔(Quarter,1/4)先生”(,而格林斯潘的黑色公包,则被比做美国总统身旁控制美国经济的“核按钮”,何况他控制的不仅是美国经济,甚至延伸影响着整个世界。“美国总统跺跺脚,打颤的不过是白宫;可格老一打喷嚏,全球就得下雨。”就是他的形象的真实写照。 相似文献

伯南克,这位长着大络腮胡子的经济学家兼美联储理事,即将成为美联储新的掌门人.在获得布什提名后,伯南克立即表示,他将尽一切力量,与美联储的同僚合作,确保美国经济维持繁荣稳定.寥寥数语向市场传达了非常明确的政策信号:在短时间内,新任联储主席不会执行与格林斯潘风格迥异的货币政策.但就未来美联储的货币政策目标而言,主张通货膨胀目标制的伯南克显然会比格林斯潘走得更远. 相似文献

Nuclear law tends to be an ‘exception’ to ordinary tort law in many ways. This is due to its early military roots and initial fears of catastrophe containment. Yet, this ‘exception’ is not justified anymore. Producing energy in nuclear power plants is business-as-usual nowadays and is insured by multinational corporations like Swiss Re, Generali, Münich Re, AXA, etc. In this article, a key exception provided by nuclear law will be explained: how suppliers and designers of defective reactors escape any responsibility in case of a nuclear accident. Two nuclear states have adopted laws that deviate from this exception: the USA and India. Indeed, in both the USA and India, suppliers and designers of defective reactors can be held liable in case of a nuclear accident. In this author’s opinion, the nuclear liability package provided for in the laws of the USA and India is a gateway to justice in case of a nuclear accident and should be an example for the rest of the world. Surprisingly, though, both countries are in disagreement on nuclear law issues. Explanations in this article will be given in simple terms, in an attempt to demystify legal issues surrounding nuclear energy. Nuclear energy should not be an exception, and Indian and US laws have understood that. 相似文献

We propose a novel methodology to define, analyze and forecast market states. In our approach, market states are identified by a reference sparse precision matrix and a vector of expectation values. In our procedure, each multivariate observation is associated to a given market state accordingly to a minimization of a penalized Mahalanobis distance. The procedure is made computationally very efficient and can be used with a large number of assets. We demonstrate that this procedure is successful at clustering different states of the markets in an unsupervised manner. In particular, we describe an experiment with one hundred log-returns and two states in which the methodology automatically associates states prevalently to pre- and post-crisis periods with one state gathering periods with average positive returns and the other state periods with average negative returns, therefore discovering spontaneously the common classification of ‘bull’ and ‘bear’ markets. In another experiment, with again one hundred log-returns and two states, we demonstrate that this procedure can be efficiently used to forecast off-sample future market states with significant prediction accuracy. This methodology opens the way to a range of applications in risk management and trading strategies in the context where the correlation structure plays a central role. 相似文献
