大中华区股票市场波动特征、关联性与一体化

大中华区由于语言和人文地理的天然联系,以及近年来两岸三地在各方面的广泛深入合作,股票市场的典型化特征出现了一定程度的趋同性。本文采用动态相关的 HYGARCH 模型对大中华区的股票市场进行研究,发现该模型能有效捕获大中华地区股票市场的波动聚类性、非对称性和长记忆性特征。动态时变相关结果表明：随着股票市场的逐渐开放以及两岸三地的通力合作,大中华区的股票市场动态相关系数总体呈现上升趋势,股票市场的一体化程度在逐步提高。     

主要股票市场指数与我国股票市场指数间的协整分析

本文应用协整分析和误差修正模型(ECM)，对沪、深股市指数和主要股票市场(美国、英国、香港和日本)之间的关系进行了实证分析。通过建立误差修正模型(ECM)，发现指数之间收益率序列具有相异的短期波动，而对沪、深股市指数和主要股票市场指数进行协整分析，我们发现国内市场与国际市场不存在协整关系，即没有长期共同趋势，得出我国股票市场与国际市场相分离的结论。     

转型期股票市场和经济增长:微观行为机制分析

本文对股票市场与经济增长的关系进行了微观分析。在建立模型的基础上分析了股票市场对经济增长作用的传导机制,结合中国转型期经济的实际情况对股票市场和经济增长的关系进行了考察和假设。从总体上说,中国的股票市场对经济增长的作用影响不大。     

中国股市与汇市波动溢出效应研究

以上证综合指数和人民币兑美元名义汇率为指标,运用多元GARCH模型对中国股票市场和外汇市场之间的波动溢出效应进行实证研究。结果表明：汇率制度改革后,我国股市与汇市存在显著的双向波动溢出效应;汇市对股市表现出较强的波动传导,而股市对汇市的波动传递则相对较弱,存在着波动传导的非对称性。     

沪深股市股指波动的协整性研究

目前沪深股票市场彼此联动的现象比较明显，但两个市场的波动性之间究竟存在怎样的内在关系，则需要从数量分析的角度来加以考察。本文运用协整分析方法来考察沪深股票市场波动的联动关系。     

Accounting Accruals and Stock Returns: Evidence from European Equity Markets

Abstract

In this paper, I show a generalisation of the negative relation of traditional accruals and percent accruals with future returns in 11 of 16 European countries. Positive abnormal returns from hedge portfolios on both accrual measures summarise the economic significance of this generalisation. The magnitude of returns obtained from traditional accruals is higher than that obtained from percent accruals, contrary to existing evidence from the U.S. capital market. The magnitude of the accrual effect on stock returns based on both accrual measures is stronger in countries with higher individualism, lower uncertainty avoidance, higher equity-market development, higher equity-market liquidity, lower transaction costs, higher analyst coverage, lower analyst optimism, and lower ownership concentration. In markets where minorities have legal protection against expropriation by corporate insiders and where accrual accounting is permitted, the accrual effect based only on percent accruals is positive. Earnings opacity does not appear to exhibit a significant influence. Overall, the evidence suggests that cross-country differences in culture, equity-market setting, analysts' research output, investor protection, and ownership structure play an important role in explaining variation on the magnitude of the accrual anomaly in Europe.     

Testing the Information Structure of Eastern European Markets: The Warsaw Stock Exchange

This paper investigates the content of the information set used by the agents in the Warsaw Stock Exchange - WSE. Three “candidate variables” are examined — consumers’ prices, the zloty/US$ exchange rate and the refinancing rate of the National Bank of Poland — with respect to three WSE stocks, from different sectors of the economy. The methodology employed supposes that the innovations in the price series are orthogonal to all variables within or outside the information set. Beyond the question of how to specify the agents expectations, the WSE trading rules and the high volatility period present in all monthly price series were additional problems to render it operational. Given the solutions adopted, in only three out of the nine cases tested, it was possible to reject the null that the candidate did not belong to the information set. This is a signal that macroeconomic fundamentals are still absent from the WSE. This revised version was published online in July 2006 with corrections to the Cover Date.     

宏观经济变量与股市关系的实证研究

本文设计了宏观经济变量与股市的传递途径模型，并利用相关分析方法，初步得出了影响股市的主要经济变量与股市的相关关系，以度量宏观经济变量变动对股市的影响幅度和方向。同时，通过案例分析方法，统计出各种类型的政策对股市的冲击强度。     

深沪股票市场非线性实证研究

对证券市场的分析有两种基本方法：线性方法或非线性方法。线性方法是金融经济学所惯用的方法,从现有文献看,对中国证券市场 的有效性检验,大都采取线性的办法。本文运用非线性方法检验中国证券市场的有效性。     

中国内地、香港与美国股票市场的长期协整关系研究

随着中国经济不断地融入国际经济环境中,中国内地证券市场的国际化进程也逐渐加快,表现为与世界主要资本市场的联动效应明显增强。本文通过运用协整检验对中国内地、香港以及美国股票市场联动效应的研究发现,金融危机改变了三地股市间的长期均衡关系。     

Be Berlin! Governing the City through Freedom

In this article, I examine how contemporary Berlin is governed, with a particular focus on the production of urban space. My points of reference are the term ‘government’ (as employed by Foucault) and the field of governmentality studies (where it is applied empirically). Based on a critical discourse and dispositive analysis of the city's current urban development policy, I propose that urban governance in Berlin may be analysed through the lens of three central dispositives: the dispositive of governing through citizenship; the dispositive of the creative city; and the dispositive of the social city. I discuss the characteristics of these dispositives of urban governance, drawing on a number of examples taken from the discipline of urban space production in order to look specifically at the aims and objectives of governance, its subjects and the ways it manifests itself. In conclusion, I suggest that the new forms of governance based on empowerment and cooperation have by no means replaced disciplinary technologies of governance, but are rather embedded within them.
