中国股票市场的周期性研究

使用一个两区制马尔可夫均值转换模型对沪深300指数月度收益率进行了实证分析。研究表明,中国股票市场收益率可以划分成两状态：＂高收益状态＂和＂低收益状态＂;市场的＂高收益状态＂总是发生在股票市场上涨阶段。     

关于我国股票市场与债券市场收益率联动性的实证研究

股票和债券的资产组合在证券投资领域是一种传统而常见的投资组合方式.为了从组合中获取最大收益和最大限度地规避风险,研究这两种资产之间的联动性问题具有重要意义.基于对股票市场与债券市场收益率联动性进行的实证分析,我们发现股票市场与债券市场收益率之间存在长期影响;股票市场与债券市场收益率之间存在领先-滞后关系;股票市场与债券市场收益率之间的月度相关性是时序变化的,可以用模型进行描述与预测.     

中国股票市场的“周内效应”

本文就中国股票市场是否存在显著的“周内效应”进行了实证分析。作者发现中国股票市场并不存在绝大多数发达国家股票市场和某些新兴股票市场所普遍具有的“星期一效应”。但是 ,用于度量股票收益率波动性的标准差却在星期一最大。较强的证据显示上海股票市场存在着日平均收益率显著为负的“星期二效应”和显著为正的“星期五效应”。较弱的证据显示深圳股票市场存在着日平均收益率显著为负的“星期二效应”和显著为正的“星期五效应”。本研究表明沪深两市在某种意义上都缺乏效率 ,且上海股市比深圳股市更加没有效率。     

通货膨胀对中国股票市场收益率影响实证研究

在现代社会,通胀已经成为了一种普遍的经济现象,文章针对通货膨胀对中国股票市场收益率的关系展开了理论与实证研究。在金融理论中,描述通货膨胀与资产收益率的关系的主要是"费雪效应"。费雪认为预期的资产名义收益率应该等于预期的实际收益率加上预期的通货膨胀率。文章立足于中国股票市场,对股票市场收益与通货膨胀率之间的关系进行实证研究,结果表明:不论是沪市还是深市,通胀率对股指收益均不存在明显的影响,即二者之间是不存在显著的相关关系的。     

后危机时代亚洲地区股票市场风险研究——基于非对称GARCH模型

运用非对称GARCH模型对后危机时代的日本、中国、印度和韩国的股票指数收益率波动性及亚洲各国股票市场的风险进行比较可发现:亚洲地区股票指数收益率的波动呈现出聚集性和持续性,股票市场存在着冲击的非对称性;后危机时代,日本和韩国股市收益与风险不相匹配,反映出发达国家股票市场的波动性显著大于发展中国家,同时,中国股票市场的抗风险能力正在逐步加强,股票市场的信息冲击也趋于平缓。     

沪深股市周末效应实证分析

周末效应也可称作星期效应，是指证券市场一周中各交易日收益率的差异。周末效应包括两大子效应，即“收益率周末效应”和“波动性周末效应”。西方学者将周末效应与市盈率效应、市净率效应、小公司效应等称为市场异例现象。市场异例导致投资者可以凭借过去信息获得额外收益。投资者根据一周期内各日收益率的差别，在高收益日卖出，低收益日进，从而使有效市场假说（EMH）失效。     

上海股票市场弱有效性的实证检验

股票市场的信息效率对于合理配置收益和风险起到关键作用,因此对于中国股票市场有效性的检验显得至关重要。运用ADF检验和游程检验对上证A股指数及收益率进行检验,结果显示上海股票市场已经达到弱式有效。     

加拿大政策利率对多伦多股票市场的影响

货币政策与股票市场的表现有密切联系.研究利率调整对股票市场表现的具体影响,对货币政策制定具有一定的指导作用.本文以加拿大多伦多股票市场为研究对象,分别采用事件分析法和构造虚拟变量进行回归分析的方法,考察了2001—2016年加拿大政策利率冲击对多伦多证券交易所指数收益率的影响.实证结果表明,加拿大政策利率冲击对多伦多股票市场具有显著影响,正政策利率冲击会导致股票市场收益率上升,而负政策利率冲击会导致股票市场收益率下降,货币政策宽松对股票市场的利好程度要优于货币政策收紧对股票市场的不利,在控制了指数历史收益情况后,上述影响依然是显著的.     

加强我国社会保障基金进入资本市场的监管

从我国2002年以来社会保障基金的投资方向和收益的情况来看,进一步拓宽社会保障基金的投资渠道,提高收益率已经迫在眉睫；另一方面,在中国股票市场持续低糜的状态下,如何发挥社会保障基金的作用,促进股票市场健康稳定发展,成为理论界和实务界共同关注的问题。国际经验表明,证券市场是各国社保基金的重要投资方向,我国监管部门应予     

CAPM在上海证券市场的实证研究

对上海股票市场的价格进行研究的目的是检验投资组合的平均收益和系统性风险β的关系是否符合传统的CAPM理论.横截面检验结论表明:上海股票市场股票的定价并不完全符合CAPM的预期,风险不是决定收益的惟一因素,而资产收益率和流通比例因素起着重要作用.     

中国转轨经济中的产权结构和市场结构——产业绩效水平的决定因素

本文利用 1 995年全国工业企业普查数据检验了中国转轨经济中产权结构和市场结构对于产业绩效的影响作用 ,发现国有产权结构变量对于产业绩效具有明显的负效应 ,产业集中率和规模变量则具有正效应。绩效的优劣主要是根据这几种因素的力度大小和相互抵消的结果来决定的。研究发现 ,国有企业通常是与垄断、缺乏竞争的市场结构密切相关 ,而可竞争的市场结构是与非国有产权或民营产权结构密切相关的。竞争市场与较低的国有产权结构的结合产生了良好的绩效 ,而竞争市场与较高的国有产权结构的不相容性则产生了不良的绩效结果。高度的国有产权结构和垄断性市场的结合 ,则会具有国有结构的负效应和某种较高垄断利润的综合效果。     

Diverse beliefs and time variability of risk premia

Why do risk premia vary over time? We examine this problem theoretically and empirically by studying the effect of market belief on risk premia. Individual belief is taken as a fundamental primitive state variable. Market belief is observable; it is central to the empirical evaluation and we show how to measure it. Our asset pricing model is familiar from the noisy REE literature but we adapt it to an economy with diverse beliefs. We derive equilibrium asset prices and implied risk premium. Our approach permits a closed form solution of prices; hence we trace the exact effect of market belief on the time variability of asset prices and risk premia. We test empirically the theoretical conclusions. Our main result is that, above the effect of business cycles on risk premia, fluctuations in market belief have significant independent effect on the time variability of risk premia. We study the premia on long positions in Federal Funds Futures, 3- and 6-month Treasury Bills (T-Bills). The annual mean risk premium on holding such assets for 1?C12?months is about 40?C60 basis points and we find that, on average, the component of market belief in the risk premium exceeds 50% of the mean. Since time variability of market belief is large, this component frequently exceeds 50% of the mean premium. This component is larger the shorter is the holding period of an asset and it dominates the premium for very short holding returns of less than 2?months. As to the structure of the premium we show that when the market holds abnormally favorable belief about the future payoff of an asset the market views the long position as less risky hence the risk premium on that asset declines. More generally, periods of market optimism (i.e. ??bull?? markets) are shown to be periods when the market risk premium is low while in periods of pessimism (i.e. ??bear?? markets) the market??s risk premium is high. Fluctuations in risk premia are thus inversely related to the degree of market optimism about future prospects of asset payoffs. This effect is strong and economically very significant.     

Beyond the efficient markets hypothesis: Towards a new paradigm

To go beyond the efficient markets hypothesis (EMH) we suppose that the stock market can be in one of three states: (1) a fundamental state, where share prices are determined largely as in the EMH; (2) a bubble or bull market state, where share prices are above their fundamental levels but are expected to continue to rise further, and (3) a bear market state, where shares are held exclusively by irrational agents and rational agents cannot exploit the overvaluation because of short-selling constraints. Also, heterogeneous rational expectations may help explain some features of stock market behaviour.     

The housing market and excess monetary liquidity in China

This study investigated the performance of the housing market in China, determining that from a long-term perspective, an equilibrium relationship exists between housing prices and output. However, the housing market may not be efficient in the short run. Based on the correlation between housing returns and the economic growth rate, 3 distinct states can be discerned in the performance of the Chinese housing market. The first state is a bubble period, during which housing returns are excessively high and negatively correlated with the economic growth rate; the second state is a correction period, during which housing prices are corrected toward market fundamentals; and the third state is a calm market period, during which no substantial performance or trends manifest. This study determined that excess monetary liquidity significantly influenced the housing market states; however, no such effect was observed when the interest rate was adjusted. Thus, the findings implicate that if the People’s Bank of China intends to avoid losing control of the housing market, it should exercise monetary control to avoid excess liquidity in the housing market.

Transitions across labor market states including formal/informal division in Egypt

This study examines the worker transitions across labor market states including formal/informal division using panel data of 2006 to 2012 from Egypt. We generate a broad set of facts about labor market dynamics in Egypt. We first develop transition probabilities by gender across different labor market states including formal/informal sectors utilizing Markov transition processes. Government employment is the most persistent labor market state for both men and women and the out of labor force is the second most persistent labor market state for women. Unemployment is the most mobile labor market state. Informal private wage work and self‐employed–agriculture are also relatively mobile labor market states. We next identify the effects of individual, household and job characteristics on different mobility patterns by estimating multinomial logit models. We find that gender, age, education, experience, and several sectors of economic activity are associated with the transition probabilities between the labor market states considered such as formal wage, informal wage, self‐employment, unemployment, government employment, and out of labor market. Education, in particular, university degree or above is noted to play a vital role in the probability of transitions across several labor market states.     

Market failure and the existence of the state: a restatement and critique

In this article the ‘market failure’ approach to the existence of the state in market economies is restated and generalized in terms of transaction costs economizing. This approach is then criticized in that it asserts the pre-existence of societal consensus regarding efficiency versus distribution. In the presence of ex-ante distributional inequalities I suggest that distribution is a more plausible determinant of the existence and functions of the capitalist state, both theoretically and empirically. The possibility has implications on the notion of state neutrality, and on viewing the market as the ‘natural’ means of allocating resources. It also questions the very need for the existence of the market.     

Inflation,a disease of society

This paper focuses on financing the welfare state expenditures in the UK. It offers a comprehensive analysis of social expenditures and taxes paid by the working population families, and an estimation of the net benefits received by them. While the subsequent analysis of the welfare state and its development primarily concentrates on the British experience, it has a broader application to other OECD countries. The UK as the most egalitarian “liberal market economy,” offers an interesting case for the study of the interaction between the welfare state expansion and economic growth. In terms of her capitalist economic structure, (interaction between market and economy) she is relatively closer to the USA and other Angelo-Saxon (liberal market) economies. In terms of her level of social expenditures, she is much closer to the European “social market economies” than the USA and other more egalitarian “liberal market economies.”     

The effect of shocks to labour market flows on unemployment and participation rates

This article presents an analysis of labour market dynamics, in particular of flows in the labour market and how they interact and affect the evolution of unemployment rates and participation rates, the two main indicators of labour market performance. Our analysis has two special features. First, apart from the two labour market states – employment and unemployment – we consider a third state – out of the labour force. Second, we study net rather than gross flows, where net refers to the balance of flows between any two labour market states. Distinguishing a third state is important because the labour market flows to and from that state are quantitatively important. Focusing on net flows simplifies the complexity of interactions between the flows and allows us to perform a dynamic analysis in a structural vector-autoregression framework. We find that a shock to the net flow from unemployment to employment drives the unemployment rate and the participation rate in opposite directions while a shock to the net flow from not in the labour force to unemployment drives the rates in the same direction.     

人民币在岸市场已经是一个 非完全定价中心*

本文的研究结果表明在岸市场依然具有人民币汇率定价中心的性质,主要体现在在岸即期和远期汇率都会对离岸远期汇率的变动有显著的均值溢出效应。而离岸即期市场对在岸即期市场存在较小幅度的均值溢出效应以及三大市场之间已经存在着一定波动和冲击溢出效应,则表明在岸市场已经不是一个完全定价中心。从溢出效应的程度和传递方向来看,稳定在岸人民币汇率定价预期仍然是降低汇率过度波动的关键。
