An investigation of the stability of returns in Western European equity markets

This paper investigates the temporal stability of various dimensions of the returns of 16 European stock markets that are relevant to an analysis of international portfolio diversification. The basic data consist of daily stock market price indices for these markets. This group of indices comprehends a wide range of stock markets differentiated by size, age and technological sophistication, but in each case located in Western Europe. Two main tests were conducted: (a) ANOVA to identify inter-temporal variability and inter-market variability over 24 three-month sub-periods from January 1989 to December 1994, and (b) cluster analysis to identify groups of markets that exhibit similar behaviour patterns. The findings suggest that, while the potential gains from an internationally diversified portfolio restricted to the equities of Western European markets appear to be substantial, the lack of inter-temporal stability in the composition of the optimal portfolio from one period to another makes these gains difficult to achieve in practice.     

What Drives European Football Clubs’ Stock Returns and Volatility?

The article studies the main determinants of European football clubs’ stock returns and volatility. A panel-data analysis of a sample of 24 European football clubs was conducted to test the influence of several variables, based on a matrix of internal/external and real/financial dimensions, on both stock returns and their volatility. The results show that clubs’ stock returns are influenced by the real and financial context and by a set of internal variables such as profit considered as a reflection of accounting discipline, capitalization as an indicator of size and stadium attendance as a proxy indicator of reputation. The volatility of stock returns seems particularly vulnerable to the overall instability on stock markets and dependent on clubs’ profit and net players’ transfers and, to a lesser extent, on sporting outcomes.     

资金流动、国际金融整合与经济增长——基于新兴市场国家面板数据

本文尝试检验东欧、东亚和拉丁美洲三大主要新兴市场国家或地区的资金流动方向及其对经济增长的影响,以及近来众所关切的全球经常账户失衡问题。实证结果显示:东欧国家收入水平与金融深化程度仍然偏低,但随着发展程度提高,未来将由资金流入转为流出。东亚国家或地区的超额外汇储备、贸易顺差与资金流出,被指控为造成美国巨额经常账户赤字与全球经常账户失衡的主要原因之一,但若能够持续金融深化的努力,资金可能回流并使全球经常账户失衡现象得以缓解。至于拉丁美洲国家的宏观经济、金融和政策变量,对于资金流动方向并无决定性影响,但宏观经济政策仍是决定资金流入能否有助于经济增长的关键因素。     

我国社保基金投资资本市场的风险及其管理——基于全球金融动荡背景下的思考

目前我国社保基金投资渠道单一,难以实现保值增值。因此,在全球金融动荡背景下,拓宽社保基金的投资渠道已经成为亟待解决的问题。本文通过对社保基金投资资本市场的风险进行鉴别和度量,针对我国社保基金运营和管理中存在的问题提出了建议,然后从回避系统性风险、降低非系统性风险、应用现代风险管理技术度量风险以及规避管理风险等四个方面提出了控制社保基金投资风险的对策。     

基于VAR模型的我国主要金融市场间波动性的关系研究

本文运用VAR模型从投资收益波动性的角度分析了我国股票市场、国债市场、企业债市场、银行间拆借市场的相互关系,运用格兰杰因果检验和脉冲分解两种方法对模型进行分析,并与已有的研究结果进行对照,研究结果表明股票、国债、企业债市场之间存在较强的相互作用,银行间拆借市场与上述三个市场的关系并不十分紧密,只是会受到债券市场的微弱的影响。要规范和做大做强股票市场,大力发展国债和企业债市场,引进更多的市场参与者,完善市场的软硬件建设,加快银行利率市场化步伐。     

An Empirical Study on China＇s Gold Futures Market Hedging Performance

本文选取2008年1月9日至2010年12月31日之间期货价格和现货价格数据,运用传统回归模型（OLS）、双变量向量自回归模型（B—VAR）、误差修正套期保值模型（ECM）、误差修正GARCH模型（EC—GARCH）对样本数据进行平稳性和协整关系检验,在估计最小风险套期保值比率的基础上发现：（1）我国黄金期货市场运行三年多来,通过黄金期货市场进行套期保值是有效的,可以较为明显地降低参与者面临的价格波动风险;（2）在具体进行套期保值操作时,应该根据套期保值时限长短的不同和预期效果的差异,采用不同的模型来合理确定自身的套期保值比例。在此基础上,本文提出了相关政策建议。     

Profit Shifting in Two‐Sided Markets

We investigate how multinational two‐sided platform firms set their prices on intra‐firm transactions. Two‐sided platform firms derive income from two customer groups that are connected through at least one positive network externality from one group to the other. A main finding is that, even in the absence of taxation, transfer prices deviate from marginal cost of production. A second result of the paper is that it is inherently difficult to establish arm’s length prices in two‐sided markets. Finally, we find that differences in national tax rates may be welfare enhancing, despite the use of (abusive) transfer prices as a profit‐shifting device.     

未雨绸缪还是杞人忧天——评“汇率浮动恐惧症”

面对金融国际化,新兴市场国应更重视汇率问题.引导新兴市场国的汇率政策选择的理论,如著名的"中间空洞理论"现在遇到越来越多的挑战,因为不少实证研究表明新兴市场国表现出"汇率浮动恐惧症".结合汇率不完全传递率的实证分析以及对贬值紧缩效应等的分析,新兴市场的"汇率浮动恐惧症"是合情但并非合理的表现,新兴市场国家事实上可以享用汇率浮动的好处,无需将自己陷入对浮动的恐惧当中,这样新兴市场国的汇率政策及汇率选择有了更大自由空间.     

我国资本市场与证券投资基金互动关系研究

资本市场与证券投资基金之间是否存在着相互促进、共同繁荣的良性互动以及如何实现,这是一个理论和实践上都存在争议的课题,本文通过构建资本市场与证券投资基金互动机制及约束条件,并以此分析中国资本市场与证券投资基金互动关系,研究表明资本市场能促进证券投资基金的发展,但证券投资基金并没有有效地促进资本市场发展
