中国股票市场发展与经济增长的实证研究

本文运用Johansen协整检验、格兰杰因果检验等计量经济学方法,通过分析我国近年来宏观数据及股市规模、流动性和波动性的季度数据,对中国股票市场发展与经济增长的关系进行了计量学检验。得出的结论是：总体上,中国股票市场和经济增长之间存在长期的均衡关系,经济增长对股市的发展具有一定促进作用,但股票市场对经济增长的作用十分有限。     

股票市场量价关系分析——模型与实证

文章将行为金融学的分析方法引入到股票市场量价关系的研究中,在考虑市场参与者非理性行为———＂急于实现盈利＂同时＂不愿结算浮亏＂的前提下,首先通过供求分析,给出股票市场中的需求曲线与供给曲线,然后设定初始均衡,采用经济学中的比较静态分析方法,研究新信息到来时对初始均衡的影响,进而分析新信息的到来对成交量和价格的影响。模型的结论是＂成交量和成交价格的变动正相关＂、＂成交量和成交价格变动的绝对值正相关＂。使用计量经济学方法,基于中国A股市场的历史数据进行了实证检验,实证结果支持了模型的结论。通过进一步分析,文章最后还得出＂投资散户是股票市场的自动稳定器＂的结论。     

证券市场的弹性分析及其应用

本文对证券市场,特别是股票市场的量价关系进行了分析,通过建立一个成交量与股价变化关系的数学模型,找出某股票在某时刻t其价格对其成交量的弹性指标,并对该弹性指标作出定性分析,结合对股票市场的长期研究,得出了一些对实际操作有指导意义的结论。这些结论将对于预测股票行情、帮助投资者在股票市场中获利和规避风险有参考价值和实际意义。     

国民经济与股市相关关系的统计分析

本文从统计实证的角度对宏观经济与股市的关系进行了分析，建立了长期的均衡模型，得出宏观经济与股市间存在互动关系，股市能够促进经济增长，宏观经济对股市有重要影响的结论。     

出版物种类与经济增长关系的实证分析——以上海市为例

用时间序列动态均衡关系分析方法,对上海市1978-2007年出版物种类与经济增长之间的关系进行研究,建立了协整方程和误差修正模型,进行了格兰杰因果关系检验,得出的主要结论是：上海市经济增长和出版物种类之间存在长期的协整关系,出版物种类每增加1个百分点,GDP增加0．773398个百分点：发现二者呈长期动态均衡关系,但目前还没有表现出直接的因果关系。     

城镇化与中国经济增长“长期均衡悖论”的实证检验

不同的研究文献对城镇化与经济增长序列是否平稳、是否存在协整关系给出了不同结论,而且不同的文献使用不同指标来表征城镇化与经济增长,并使用不同的模型形式进行实证研究。那么不同类型指标与模型选择是否会影响分析结论?城镇化与经济增长是否客观上存在长期均衡关系?使用1978~2011年的相关数据进行实证分析后发现,不同指标和模型选择将会对模型结论产生重大影响,甚至会得出相反结论。     

我国股票市场发展对经济增长影响的实证分析

一、研究文献回顾与综述 对于股票市场发展与经济增长的关系,前人做了许多研究,从研究结论得出的观点大致可以分成两种,一种观点认为股票市场与经济增长有相关关系。Atje和Jovanovic（1993）通过对72个国家1980～1988年的样本数据进行OLS回归分析得出,一国股票市场的相对规模有助于解释人均国内生产总值增长的结论,说明股票市场发展对经济增长有积极影响。     

房地产价格与经济增长的动态关系分析——以内蒙古为例

本文运用协整理论,对1999～2010年间内蒙古的房地产价格与经济增长的数据进行分析研究,结果表明两者之间存在长期稳定的均衡关系。通过对其建立误差修正模型,可以看到两者之间存在长期均衡和短期波动的关系,房地产价格与经济增长互为格兰杰原因,最后提出了房地产业与经济增长和谐发展的政策建议。     

我国财政支出对职工收入影响的实证研究

文章对财政支出与职工收入之间的关系进行了实证研究,分析了财政支出对职工收入增长的影响。通过协整关系检验得出财政支出与职工平均工资存在长期均衡关系,并建立了误差修正模型。根据模型及变量间因果关系,为落实财政政策提高职工工资水平提出了一些建议。     

成交量与股价波动ARCH效应的实证研究

本文通过建立增广GARCH-M模型,选用1998年1月5日至2004年2月26日间上海证券交易所的交易数据,对我国股票市场波动的ARCH效应与股票成交量之间的关系进行了实证研究.结果显示:(1)股票市场波动性与同期股票成交量之间存在较强的正相关关系,并且股票市场波动的持久性特征在考虑成交量这一因素后而明显减弱;(2)股票成交量中含有有关市场波动的信息,但成交量的引入并没有消除股价波动的ARCH效应,从而说明还有其他因子影响着股票市场的波动特征.     

投资者情绪、股票市场流动性和经济增长

采用2000—2009年的GDP、股票市场流通市值以及交易值的季度数据,从实证角度对此时段的投资者情绪、股票市场流动性和资本化率进行计量分析,通过ADF单位根检验、Johansen协整检验及Granger因果检验研究投资者情绪、股票市场流动性和股票市场发展之间的关系,进而揭示了投资者情绪影响经济增长的途径。结果显示,投资者情绪和股票市场流动性是经济增长的格兰杰原因。     

流动性过剩影响因素的实证分析

通过货币的供求对比测度出流动性过剩,采用主成分分析方法研究了流动性过剩的影响因素。实证结果表明,货币存量的持续高位、经济增长、持续低利率与人民币升值、物价指数的高涨、外汇储备和净出口增加导致流动性过剩,资产价格与流动性过剩之间存在反向关系,各因素之间存在着交互影响。实证结果与理论分析结论高度吻合。     

Cash-flow news,market liquidity and liquidity risk

This article adopts Campbell's (1991) return decomposition model to decompose the unexpected stock return and unexpected excess stock return in the US stock market. The study also investigates the factors that cause the shock to stock return and excess stock return. We further examine the responses of stock market to cash-flow news, expected stock return news, expected excess stock return news and interest rate news. Last, we examine the reaction of market liquidity, liquidity risk and abnormal trading volume to cash-flow news, expected stock return news, expected excess stock return news and interest rate news. Our main findings are summarized as follows: first, cash-flow news is the main driver of stock return and excess stock return in stock market. Second, the dividend payout ratio is able to predict stock return and excess stock return. Third, under the model of stock return variance, unexpected market liquidity and unexpected liquidity risk are negatively related to expected stock return news, but not related to cash-flow news. Fourth, under the model of excess stock return variance, unexpected market liquidity and unexpected liquidity risk are negatively related to cash-flow news, expected excess stock return news, and interest rate news.     

What determines China's inflation?

We examine determinants of inflation in China. Analyses of both year-on-year and month-on-month growth data confirm that excess liquidity, output gap, housing prices, and stock prices positively affect inflation. Impulse response analyses indicate that most effects occur during the initial five months and disappear after ten months. Effects of real interest rates and exchange rates on inflation are relatively weak. Our results suggest that the output gap is as important as excess liquidity in explaining the inflation trajectory. The central bank should closely monitor asset prices given their spillovers to inflation. Currently liquidity measures are still central for controlling inflation, but further liberalization of interest rates and exchange rates are crucial.     

Can growth-enhanced monetary policy improve welfare when people seek social status?

This paper examines the growth and welfare effects from an increase in the rate of money supply in an Ak type growth model with a relative wealth-enhanced social status motive, production externalities, and liquidity constraints. When only consumption is constrained by liquidity, fast money supply can hasten output growth unless seigniorage revenue is wasted and production externalities do not exist. We find that even though money growth normally promotes economic growth, it does not improve welfare when capital stock is over-accumulated. In general, an optimal monetary policy minimizes seigniorage. Our results also conclude that the optimal monetary policy rarely follows the Friedman rule.     

Intergenerational Mobility and the Process of Development

This paper offers an explanation for some evidence that intergenerational earnings mobility is higher in more developed economies and that mobility is positively correlated with wage equality. In the model mobility promotes economic growth via its effect on the accumulation and allocation of human capital. Growth influences mobility via its effect on incentives to acquire education and its effect on liquidity constraints upon such acquisition. In the process of development mobility increases and the distribution of education becomes better correlated with ability. Redistributive policy has a negative effect on growth in developed economies and a positive effect in developing economies.     

International Financial Liberalization and Economic Growth

This paper pulls together existing theory and evidence to assess whether international financial liberalization, by improving the functioning of domestic financial markets and banks, accelerates economic growth. The analysis suggests that the answer is "yes." First, liberalizing restrictions on international portfolio flows tends to enhance stock market liquidity. n turn, enhanced stock market liquidity accelerates economic growth primarily by boosting productivity growth. Second, allowing greater foreign bank presence tends to enhance the efficiency of the domestic banking system. In turn, better-developed banks spur economic growth primarily by accelerating productivity growth. Thus, international financial integration can promote economic development by encouraging improvements in the domestic financial system.     

基于机构投资者交易需求的中国股市流动性研究

基于机构投资者的交易需求,结合对15家机构投资者的调研,通过实证数据发现:我国股市的流动性水平高于美国NYSE等世界其他主要证券市场,机构投资者一般对国内股市整体流动性水平比较满意。但是我国股市流动性波动率高,并且和市场回报率之间存在单向格兰杰因果关系。对机构投资者来说,当前我国股市主要的流动性问题不是流动性水平过高或过低的问题,而是流动性风险过高并难以和价格风险相分散。     

关于货币危机后经济衰退的经验分析

文章以1990年以来的近200次货币危机为样本,对货币危机后的经济衰退进行了经验分析.研究发现,危机前的经常账户状况、外债余额占GDP比例、国际流动性指标等经济变量以及危机后的汇率制度都不会显著影响到危机后的经济衰退.另外,危机后的经济衰退与危机国政府在危机中是否抛售外汇储备、是否采取汇率贬值都没有明显关系.但是经济分析的结果表明,危机前的失业率和汇率制度以及危机中是否提高利率等因素对危机后的经济衰退有显著作用.     

Money and capital as competing media of exchange

We construct a model where capital competes with fiat money as a medium of exchange, and establish conditions on fundamentals under which fiat money can be both valued and socially beneficial. When the socially efficient stock of capital is too low to provide the liquidity agents need, they overaccumulate productive assets to use as media of exchange. When this is the case, there exists a monetary equilibrium that dominates the nonmonetary one in terms of welfare. Under the Friedman Rule, fiat money provides just enough liquidity so that agents choose to accumulate the same capital stock a social planner would.
