《Journal of Policy Modeling》2020,42(6):1187-1207
This paper investigates the determinants of countries’ choices of monetary policy framework. A brief narrative focused on groupings of countries motivates an econometric analysis which draws on previous work on the determinants of exchange rate regimes, bringing in standard factors as well as the trade networks of potential anchor currency blocs and the financial market depth that are emphasised in the narrative. The model turns out to be able to predict three quarters of countries’ choices, and there is no obvious systematic pattern in the errors. The results have important implications for how countries should choose their monetary policy frameworks.  相似文献

1937年上海“纱交风潮”系上海纱布交易所爆发的影响巨大且后果最严重的一次风潮。此次风潮的起因是多方面的,其中最根本的原因是孔家官僚资本为获取巨利插手纱交、操纵市场、大搞投机活动。这场风潮促使国民政府颁布《取缔上海纱布交易所投机办法》,并对此次风潮进行“澈查”,然“澈查”结果却虎头蛇尾。由此看出,国民政府与官僚资本的密切关系,即官僚资本已凭借各种超经济特权在国民经济中取得了独特的优势地位。  相似文献

Diagnostics for dependence within time series extremes   总被引:1,自引:0,他引:1  
Summary. The analysis of extreme values within a stationary time series entails various assumptions concerning its long- and short-range dependence. We present a range of new diagnostic tools for assessing whether these assumptions are appropriate and for identifying structure within extreme events. These tools are based on tail characteristics of joint survivor functions but can be implemented by using existing estimation methods for extremes of univariate independent and identically distributed variables. Our diagnostic aids are illustrated through theoretical examples, simulation studies and by application to rainfall and exchange rate data. On the basis of these diagnostics we can explain characteristics that are found in the observed extreme events of these series and also gain insight into the properties of events that are more extreme than those observed.  相似文献

信息时代中 ,由于网络在查找资料上的方便与快捷 ,已经对当前高校的院系资料室形成较大的冲击 ,资料室存在的合理性因此受到质疑。然而 ,笔者认为网络可以取代的只是资料室的显性功能 ,而资料室本身所具有的隐性功能则是网络所无法替代的。本文主要以资料室的隐性功能的阐释为出发点 ,认为环境与交往是资料室隐性功能发挥的重要机制 ,进而剖析高校院系资料室隐性功能的具体体现  相似文献

American options in discrete time can be priced by solving optimal stopping problems. This can be done by computing so-called continuation values, which we represent as regression functions defined recursively by using the continuation values of the next time step. We use Monte Carlo to generate data, and then we apply smoothing spline regression estimates to estimate the continuation values from these data. All parameters of the estimate are chosen data dependent. We present results concerning consistency and the estimates’ rate of convergence.  相似文献

This study explores differences in inter-household exchange of goods and services in Anglo- and Mexican-American families controlling for income level and for ethnicity. The extent of such exchange, its perceived importance to the family's quality of life, satisfaction with the exchange, and the relation of persons in the exchange process are examined. Significant differences are found more often between higher income Anglo- and Mexican-Americans than between low-income families, both in the family providing goods and services for others and in the receipt of them. Higher income Mexican-American families are more likely than their Anglo- counterparts to exchange with relatives. Ethnic effects are more prevalent in higher income households than in low-income households. Economic effects are more predominant than ethnic effects.This study contributes to interregional Agricultural Experiment Station Research Project NC-128, Quality of Life as Influenced by Area of Residence.

In this article, a warm standby n-unit system is studied. The system is operational as long as there is one unit normal. The unit online, which has a lifetime distribution governed by a phase-type distribution, is also attacked by a shock from some external causes. Assume that shocks arrive according to a Poisson process. Whenever an interarrival time of shock is less than a threshold, the unit online fails. The lifetimes of the units in warm standby is exponentially distributed. A repairman who can take multiple vacations repairs the failed units based on the “first-in-first-out” rule. The repair times and the vacation times of repairman are governed by different phase-type distributions. For this system, the Markov process governing the system is constructed. The system is studied in a transient and stationary regime; the availability, the reliability, the rates of occurrence of the different types of failures, and the working probability of the repairman are calculated. A numerical application is performed to illustrate the calculations.  相似文献

公元13世纪回回人从灿烂的阿拉伯伊斯兰文化的高峰走来,进入高度发达的中国的汉文化领域。阿拉伯伊斯兰文化是形成发展中的回回民族的一种文化形式,它从真主独一的信仰及其功修、伦理道德、价值观念、生活方式等方面维护着形成中的回回民族的民族的同一性。在汉文化面前如何保存自己固有的阿拉伯伊斯兰文化,使其继续传承,不致中断,这是摆在回回人面前的新问题。同时,为了民族的生存发展,回回人必须学习汉文化,以适应中国传统社会,以被中国传统社会所接纳。而汉文化是一  相似文献

刘智作为明末清初的著名汉文译著家,他的翻译、介绍和著述充满了时代的创新性、开创性.刘智译著中哲学思想的丰富来源于他对伊斯兰哲学和思想的深刻学习和理解,更得益于他对中国传统哲学的悉心了解和系统掌握.其中,刘智对伊斯兰教哲学史上著名的哲学家、思想家和诗人阿布德·热哈曼·贾米(Abd al-Rahman Jami,伊历817-898年,1414-1492)的<勒瓦一合>(Lawa'ih)的译介,以<真境昭微>而著名,并反映了刘智译介过程中的创造性特征.<真境昭微>既忠实于原著,又以中国穆斯林的聪明才智超越了原文的文本,进行了汉语语境中的创造性表述和中国哲学范畴的恰当转化,从而以汉语的话语更直观地体现了伊斯兰哲学,特别是伊斯兰苏非哲学思想中"存在统一论"思想,以及苏非追求和实践自我超越和心灵升华的理想境界.在中国伊斯兰哲学、伊斯兰思想史上具有重要的理论价值和现实意义,也更好地体现了伊斯兰哲学和中国哲学的交流和融通,是人类智慧和思想间相互学习、理解、交流和对话的一幅历史风景画.  相似文献
