汇率与股价变动关系:基于汇改后数据的实证研究 总被引:24,自引:0,他引:24
研究我国2005年7月汇率制度改革后汇率与股市的关系及其传导机制,有助于深刻认识金融市场联动特征,对于防范金融市场风险和完善我国资本市场、外汇市场等的改革具有重要的理论和实践意义。本文实证发现了汇率和股价存在着长期均衡的协整关系;从长期来看,两者关系符合流量导向模型,上证指数受到汇率长期影响,从短期来看,股市和汇市存在着交互影响,汇率变化影响股指变动有时滞。运用滚动窗口的Granger检验和加入其他重要宏观变量的多变量协整检验,本文证明了这种长期关系具有较强的稳健性。进一步从板块指数与汇率的关系来看,房地产、金融、民航、石化、钢铁指数均与汇率存在着长期的协整关系,汇率变化是这些板块指数的Granger原因。最后,本文对实证结果做出分析并指出了相应的政策含义。 相似文献

This paper tackles the question of whether a cross-sectional perspective on monetary policy is capable of explaining movements in global commodity prices. In this vein, we contribute to the rich literature on global liquidity in two different ways: on the one hand, to achieve a global series in terms of common monetary policy shocks, we propose a distinction between common and idiosyncratic factors across economies, as proposed by Bai and Ng (2004). Our second innovation stems from the consideration of a Markov-switching vector error correction model when analyzing time-varying short-run dynamics. Having identified the long-run structure which includes a proportional relationship between commodity prices and global liquidity in the first step, our results indeed show that the impact of a global liquidity measure on different commodity prices is significant and varies over time. One regime approximately accounts for times where commodity prices significantly adjust to disequilibria, while the second regime is characterized by either a weak or no commodity price adjustment. The fact that global liquidity also reacts to disequilibria in a specific regime demonstrates the two-way causality between monetary policy and commodity prices. 相似文献

Results from cointegration tests clearly suggest that TFP and the relative price of investment (RPI) are not cointegrated. Evidence on the alternative possibility that they may nonetheless contain a common I(1) component generating long-horizon co-variation between them crucially depends on the fact that (i) structural breaks are, or are not allowed for, and (ii) the precise nature and timing of such breaks. Not allowing for breaks, evidence points towards the presence of a common component inducing positive long-horizon covariation, which is compatible with the notion that the technology transforming consumption goods into investment goods is non-linear, and the RPI is also impacted upon by neutral shocks. Allowing for breaks, evidence suggests that long-horizon covariation is either nil or negative.Assuming, for illustrative purposes, that the two series contain a common component inducing negative long-horizon covariation, evidence based on structural VARs shows that this common shock (i) plays an important role in macroeconomic fluctuations, explaining sizeable fractions of the forecast error variance of main macro series, and (ii) generates ‘disinflationary booms’, characterized by transitory increases in hours, and decreases in inflation. 相似文献

It is well known that intra-industry trade and cross-border production networks have promoted economic growth and regional integration in East Asia. However, regional supply and production chains may have been formed differently across industries, reflecting different degrees and a different scope of regional economic linkages at an industry level. This paper makes a threefold contribution. First, to assess industry-level differences, this study adopts the generalized purchasing power parity (G-PPP) model using industry-specific producer prices. Second, the momentum threshold autoregressive (M-TAR) model is employed to allow for possible nonlinearity arising from the dynamic nature of regional economic growth and development. Third, the Granger causality test is also conducted to assess whether regional economies have autonomously integrated. The empirical results reveal that economic integration has progressed more autonomously in the electrical industry, as well as in the transportation equipment industry, as China and the ASEAN countries have become the final destination markets for finished products in these two industries. 相似文献

This study examines the sustainability of current account deficits (CADs) and validity of intertemporal budget constraint (IBC) for 24 OECD countries. While the OLSEG, ML system, and OLSGH estimates of the model do not provide support, the GMM, DOLS, and NLLS estimates provide consistent support for the sustainability of CADs across most countries. The estimates of the model with multiple structural breaks reinforce the sustainability of CADs. The results provide dominant support for the sustainability of CADs and validity of IBC across most countries. The CADs are only short-run phenomena and are balanced by future surpluses. 相似文献

Both cointegration methods, and non-cointegrated structural VARs identified based on either long-run restrictions, or a combination of long-run and sign restrictions, are used in order to explore the long-run trade-off between inflation and the unemployment rate in the post-WWII U.S., U.K., Euro area, Canada, and Australia. Overall, neither approach produces clear evidence of a non-vertical trade-off. The extent of uncertainty surrounding the estimates is however substantial, thus implying that a researcher holding alternative priors about what a reasonable slope of the long-run trade-off might be will likely not see her views falsified. 相似文献

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. 相似文献

In this study, we attempt to examine the possibility of emergence of significant fluctuations of the exchange rates in the
future for the candidate EMU countries. In doing so, we estimate the equilibrium rate of the nominal effective exchange rate
for Poland, Hungary, Slovak Republic and Malta through the BEER and PEER approaches. While the PEER-based estimation implies
a large misalignment rate for the Hungarian forint, the BEER-based analysis shows that the present exchange rates of the countries
considered do not deviate significantly from their equilibrium rates. As a consequence, based on BEER analysis, we do not
expect large fluctuations in the effective exchange rates among the currencies considered. Hence, the relevant effective exchange
rates are expected to be relatively stable. As a matter of fact, the entry of those countries into EMU is not expected to
weaken the stability of Euro.

针对我国2001~2010年季度数据,通过使用协整关系检验、格兰杰因果检验以及方差分解分析方法进行实证研究发现,长期内我国货币供给的变化与物价和产出的变化之间存在唯一的协整关系;同时存在一个单向的Granger因果关系:货币供给增长率是物价水平增长率的Granger原因,即长期内货币供应量仅对物价水平产生影响。最后根据实证分析结果对货币政策选择提出政策建议。 相似文献
