Dynamic and asymmetric impacts of macroeconomic fundamentals on an integrated stock market

A large body of evidence indicates that macroeconomic and financial variables are dynamically interrelated. In an international setup, we analyze the transmission mechanisms of macroeconomic shocks on the stock market of a small open economy in an increasingly integrated world. We use a time-varying vector error correction model (VECM) that allows analysis of asymmetric impacts that depend on the state of the business cycle. A special focus is directed on monetary policy surprises, where we find that foreign shocks exert a strong influence on an integrated stock market, and that the stage of the business cycle heavily affects the signals of the shocks.     

国际证券市场联动程度的实证分析

20世纪80年代以来,通过国际证券投资分散风险已经形成一种可行手段,然而,随着全球经济一体化趋势的强化,国际证券市场也正在经历着一体化趋势,证券市场联动关系越来越明显,这必然会使国际投资多样化空间变小,进而会侵蚀掉国际多样化投资收益.有鉴于此,本文使用协相关参数分析、平稳性检验、多元协整检验、协整向量参数零配载限制检验、基于VECM的Granger因果性检验等计量技术测度国际证券市场联动程度,为国际证券投资提供量化参考.     

国际贸易与技术进步的长短期因果关系检验——基于VECM的实证分析

本文运用向量误差修正模型(VECM)对中国的进出口与技术进步的协整因果关系作实证分析,得出以下结论:我国的技术进步和进出口之间存在长期的均衡关系。从长期来看,我国的技术进步促进了进口和出口的增长;出口和进口互为因果关系,但是出口和进口对技术进步的促进作用不是很显著。从短期来看,出口是技术进步的Granger原因,但技术进步不是出口的原因;进口不是技术进步的Granger原因,技术进步也不是进口的原因;进口是出口的原因,但出口不是进口的原因。     

Risk-Taking Behavior and Capital Adequacy in a Mixed Banking System: New Evidence from Malaysia Using Dynamic OLS and Two-Step Dynamic System GMM Estimators

This study is the first attempt to investigate the relationship between the level of risky assets and capital level in a mixed Malaysian banking system covering 83 months starting December 2006. The results of dynamic ordinary least squares indicate positive relationship between capital ratio (CAR) and risk-weighted asset ratio (RWA) in the long run. Furthermore, the causality analysis based on panel vector error correction model (VECM) and two-step dynamic system generalized method of moments indicates unidirectional causality from CAR to RWA. Our results further suggest that higher capital growth and capital buffer provide an extra cushion for the Malaysian banks to pursue relatively riskier financial activities, and the nature of risk-taking behavior of Islamic banks follows that of the conventional banks.     

Cointegration in China's log import demand: Price endogeneity and structural change

The monthly data of China's log import from January 2000 to December 2013 are used to estimate the import demand elasticities, with the consideration of possible price endogeneity due to China's large share of the international log market, and structural break caused by global financial crisis in 2008. To address the possible structural break, cointegration tests allowing for a deterministic shift in the level of the variables are employed, and a two-stage estimation with top-down sequential elimination algorithm is performed on the restricted subset VECM. The results demonstrate that there exists a long-run cointegration relationship between China's log import and the explanatory variables. The import elasticities of macroeconomic development and import price are around 0.76 and −0.81, respectively. Other things being equal, the structural break would induce a 29.6% decline in China's log import. All the above parameters are significant at the 1% risk level. Furthermore, the contribution decomposition analysis suggests that China's macroeconomic development plays a dominant role in determining its log import, which implies that China's log import would not increase as quickly as before, given that its economy is shifting into the “New Normal State”. This conjecture is supported by our simulations, which indicate that, by 2020, the growth rate of China's log import will be lower than it has been in the past and the import volume would be approximately 1.1–1.6 times greater compared to imports in 2013.     

中国股票市场与宏观经济关系的实证分析

证券市场是宏观经济的"晴雨表",股票市场与宏观经济的关系一直是一个研究的热点问题.那么在现实中,中国股市能否有效的反映中国经济的走势呢?宏观经济是否有效地影响股市的变动?文章期望通过对1996年1月到2006年10月的上证指数与宏观经济各指标(如工业增加值、狭义货币供应量、广义货币供应量、外汇储备、银行间7天同业拆借利率)关系的实证分析,揭示我国股票市场价格波动与宏观经济变化之间关系,进而来检验资本市场改革的成效.     

货币政策背景下房价的变动关系研究

本文在货币政策传导理论的基础上,通过向量误差修正模型(VECM)实证分析了房价在货币政策传导过程中的作用。通过分析可知,房价在货币政策传导过程中起到了一定的作用,房价渠道的传导效率整体而言比较高,由此而知货币政策和房价之间存在着一定程度的关系。     

FDI、国际贸易及我国经济增长的协整分析与VECM模型

本文利用我国1983-2004年的经济数据进行实证检验,根据协整理论建立向量误差修正模型(VECM)。实证结果说明外国直接投资、国际贸易与经济增长间具有长期均衡关系,且我国国内生产总值的增长与外国直接投资有双向因果关系,但相互影响的程度不同;我国为出口导向型经济增长国家且外国直接投资对国际贸易具有促进作用.     

经济增长与收入分配间的相互作用机制及其实证分析——基于有约束条件的VECM

本文提出经济增长与收入分配间的相互作用机制,在这基础上利用带有两个协整的VECM对该机制进行实证.结果表明:改革开放以来我国收入分配通过降低物质资本和人力资本效力影响经济增长,且金融发展程度有助于缓解收入分配对经济增长这种的负作用;经济增长通过物质资本途径扩大收入差距,通过人力资本途径缩小收入差距.     

The Relationship Between REITs Returns and Inflation: A Vector Error Correction Approach

Previous studies show that REITs returns and inflation arenegatively related. This paper reexamines this perverse inflation hedgephenomenon by investigating the relationship among REITs returns, realactivities, monetary policy and inflation through a Vector ErrorCorrection Model. Empirical results show that inflation does notGranger-cause REITs returns and that REITs returns signal changes in monetary policy. The observed negative relationship between REITs returnsand inflation is merely a proxy for the more fundamental relationshipbetween REITs returns and other macroeconomic variables.
