    On the Procedural Way to Regulate Transnational Regulation of Finance from a Reflexive Law Perspective

    本文的研究背景为金融监管领域在应对负外部性问题上,对于法律与金融监管的关系这一基础性问题关注不够。本文研究的问题是如何规范金融跨国监管关系。本文的命题是需要通过程序化路径来规范金融跨国监管关系。本文在观点上主张这种程序化路径为问责制,并进而主张通过“重程序、轻实体”的立法思路来提升新兴市场国家和金融消费者参与金融跨国监管关系的自主程度。在具体制度安排上,本文认为可以强化以金融稳定理事会(FSB)为代表的多边领域同行评议、透明度等程序性机制来“内化”国家/私人“自主”决策所可能带来的负外部性;通过多方参与、公开磋商等程序和公司治理来规范私人监管俘获,以“监管等效”等程序性机制来引导监管套利,促进...This dissertation focus on how to reduce tansnational negative externalities through regulating transnational regulation of finance (TRF).The theme is that a procedural way is needed to regulate TRF.

    近年来经济全球化和信息化的发展极大地改变了跨国公司经营和竞争的环境,国际服务外包成为跨国公司降低经营成本、提高核心竞争力的战略选择。同时,随着国际服务外包规模的扩张,也推动了全球新一轮的产业转移,为发展中国家承接服务外包,提升产业结构,促进经济发展提供了机遇。许多国家纷纷地进入到争夺这份市场的竞争中来,其中走在前列的有印度、爱尔兰、菲律宾等等。而我国承接国际服务外包起步较晚,服务企业缺乏相关的经验,与国际服务外包配套的法律法规也没有形成完整的体系,从政府到企业对国际服务外包的认识还有待提高。本文则以国际服务外包为研究对象,系统地分析了国际服务外包的内涵,阐述了产生国际服务外包的理论基础和促成国...With the development of Globalization and Information Technology, the environment where Multinational Corporations (MNCs) survive and compete with each other has been dramatically changed.

    约翰•马歇尔是美国第四任首席大法官,在他长达34年有余的大法官生涯中,他领导最高法院的同事们,对一系列重要的宪法案件做出了独到的解释,不仅改变了最高法院宣布法院意见的方式——由法官逐一发表意见到法院一个声音说话,加强了最高法院的权威;而且在这一系列重要判决中,全面激活了宪法文本中的“最高条款”、“契约条款”、“必要与适当条款”、“商事条款”,把宪法文本变成了生活中实实在在的宪政。如果说1787年宪法确定了美国的宪政框架,提出了法治的目标,那么马歇尔领导的最高法院则充实了这个框架,实践了法治的理念。 国内学术界对于马歇尔与司法审查制度的确立有较多的论述,但关于马歇尔在美国宪政史上的...John Marshall was the fourth Chief Justice of the United States, in his more than thirty-four-years tenure, he led the Supreme Court colleagues to interpret the Constitution in a series of important constitutional cases.

    相关性分析是一个重要的金融研究课题,被广泛运用于风险管理、资产定价和资产配置等领域。Copula函数与传统的相关分析工具相比,具有两个明显的优势:第一,它对金融市场的线性和非线性、对称和非对称的相关关系都能较好地描述;第二,它可分析变量间的相关结构。由Copula导出的下尾相关系数,可以度量股票下跌的风险,能为风险厌恶的投资者提供资产选择的有效信息。因此,本文研究尾部相关系数的资产选择问题有一定的理论和现实意义。 本文首先介绍了Copula定义和类型、尾部相关系数的概念,以及基于极值模型下尾相关系数的计算方法。接着,本文借助Rietz的理论模型,分析了以下尾相关系作为资产选择指标的理论依据。...Correlation analysis is an significant issue, and plays an important role in the fields of asset pricing, asset allocation and risk measurement etc .

    20世纪七八十年代,美国中心城市,特别是东北部和中西部的老工业城市出现了明显的衰退现象,引起学界和政界人士的广泛关注。为拯救中心城市,很多学者和政要提出或尝试了众多改革方案。其中,安东尼·唐斯的“开放郊区“和戴维·腊斯克的“没有郊区的城市“从区域发展的角度,提出通过整合大都市区、将郊区和中心城市合二为一的方法来解决中心城市问题。虽然在现实政治中,这些主张很难得到全民的认可,却不失为一种改革的难得思路。In the 1970s and 1980s,America central city,especially the old industrial ones in the northeast and central-west began declining apparently.It caused the concerns of the scholars and politicians.To save the central cities,many scholars and politicians tried many reforming proposals.From a perspective of region development,Anthony Downs and David Rusk each brought out a proposal of combine the central city and the suburb to solve this problem.Although it is hard to be sancti?ed in the practice of politics,it is a good idea of reforming
