汇率波动率与中国对主要贸易伙伴的出口

本文研究汇率波动率对中国向三个主要贸易伙伴美国、欧盟和日本出口的影响。通过协整检验,误差修正模型和Granger非因果检验等方法估计变量间长短期的关系。研究表明,中国向美国和欧盟的实际出口与实际汇率波动率存在长期显著的负相关关系,而中国向日本的出口与汇率波动率无关。短期内汇率波动率只影响中国向美国的出口,对向欧盟和日本的出口没有影响。     

关于我国农村金融与农业技术进步的实证分析——基于时间序列数据的研究

金融发展通过＂资本积累＂和＂技术进步＂两条途径来实现对经济增长的影响,技术进步才是决定长期经济增长的关键因素。判断（农村）金融能否可持续发展的标准应该是其能否促进（农业）技术进步。基于1985-2005年的时间序列数据的实证分析,认为我国农村金融发展与农业技术进步之间存在着长期的、均衡的、单向因果关系,即农业技术进步对农村金融发展有着推动作用,而农村金融发展对我国农业技术进步的作用不明显。因此,我国农村金融深化改革应该以促进农业技术进步为导向,以实现农村金融资源的优化配置。     

A multivariate time series analysis of energy consumption,real output and pollutant emissions in a developing economy: New evidence from Nepal

Mountain economies will have to play a central role in attaining the global pursuit of green economic growth as crucial bearers of ecosystems goods and services. However, these economies are not adequately represented in the development policy debates in spite of their fundamental importance towards global sustainable development. This study examines the inter relationships between energy consumption, output and carbon emissions in a developing mountainous economy using an augmented Vector Autoregression model. Time-series data over the period 1975–2013 is studied applying a multivariate framework using population and gross fixed capital formation as additional variables for Nepal. Testing for Granger causality between integrated variables based on asymptotic theory reveals a long-run unidirectional Granger causality running from GDP to energy consumption, and a unidirectional Granger causality running from carbon emissions to GDP. We suggest that the government of Nepal can address energy poverty by accelerating the adoption energy conservation policies such as rationing energy consumption and energy efficiency improvements to narrow the energy supply-demand gap. The opportunity to promote the uptake of decentralised off-grid renewable technologies in remote areas and the large scale development of hydropower at the national level also needs to be prioritized. Our results remain robust across different estimators and contributes to an emerging literature on the nexus relationships between energy consumption, income and carbon emissions in mountainous developing economies.     

Are imports and remittances cointegrated for the Central and Eastern European countries?

In this article, we investigate the existence of long-run common trends between imports and remittances in 11 Central and Eastern European countries which are part of the European Union. Using the Engle–Granger two-step procedure, we determine that for all countries in our sample there are no long-run common trends (no cointegration) between imports and remittances. However, the results are mixed when running a Granger causality test. For nine countries, we can establish either a bidirectional or unidirectional Granger causality, indicating that past values of one variable have predictive content on the other variable. In two countries, there is no Granger causality between imports and remittances.     

区域金融发展与经济增长的实证研究——以江苏省为例

本文首先说明金融部门促进经济增长的内在机制的内生增长模型。在实证研究部分,本文改变以往研究中使用国际通用指标的做法,针对我国经济转型和银行主导金融体系的特点,使用了符合实际的经济增长指标和金融发展指标。在考虑变量的平稳性之后,模型通过了自相关检验,最后,由格兰杰检验来探讨金融发展与经济增长的因果关系,结果表明金融发展与经济增长之间存在双向因果关系。     

湖北物流业与经济发展的实证研究

分析湖北发展物流业对经济增长的前项效应、后向效应和旁侧效应,阐明发展物流业可以促进湖北产业结构的优化。提高湖北综合经济实力。并运用协整理论、Granger因果检验定量分析了湖北物流业与经济发展之间的关系,结论是湖北物流业与经济发展具有长期稳定的协整关系．湖北物流业是经济发展的原因。     

基于VAR模型的港口与临港城市经济增长协整关系研究

运用Jonhansen协整检验和Granger因果检验等计量经济方法,选取连云港港1988-2007年货物吞吐量和第一、二、三产业的GDP数据为样本,从第一、二、三产业分别考察连云港港与城市经济增长的关系。实证结果表明,连云港市第一、二、三产业增长与港口货物吞吐量之间存在长期协整关系,在短期内,第一产业增长和第二产业增长与所对应的港口货物吞吐量之间存在双向因果关系,第三产业港口货物吞吐量是第三产业增长的Granger原因,反之这种关系不成立。     

THE STOCK MARKET, HOUSING AND CONSUMER SPENDING: A SURVEY OF THE EVIDENCE ON WEALTH EFFECTS

Abstract.  This paper examines the time-series and micro-econometric evidence on the relationship between stock and house prices and consumer spending. The time-series studies distinguish between short-run and long-run links between consumption, income and wealth. They allow us to identify which variables adjust to restore the long-run equilibrium in the case of a shock, and to determine the time taken by the adjustment process. The micro-econometric literature improves our understanding of the link between wealth and expenditure and distinguishes among the alternative hypotheses – of direct wealth effect, common causality and collateral channel – that have been proposed to explain this relationship. The relationship between wealth and consumer spending appears to be strong, but there is some disagreement as to its size and nature. Furthermore, there appear to be some important differences across countries, which should be allowed for by policy makers when appraising the policy implications of a change in asset prices.     

基础设施投资与吸引外国直接投资关系的实证研究——基于我国经济转型期二者因果关系的检验

本文在现有国内外研究的基础上,依据我国改革开放20多年来的实际数据,针对基础设施投资与外国直接投资(FDI)之间的相关性进行了协整检验和格兰杰检验,结果发现:二者之间不仅存在协整关系,还存在单向的格兰杰因果关系,即FDI是带动基础设施投资的格兰杰原因,而基础设施投资并不是引致FDI增加的格兰杰原因。本实证检验还用事实证实了目前许多地方政府以增加基础设施投资来吸引外商投资的盲目性。     

Cointegration and causality in the Asian and emerging foreign exchange markets: Evidence from the 1990s financial crises

This article examines the cointegration level, changes in the existence and directions of causality of the foreign exchange (FX) rates in the Asian and emerging markets during the 1990s financial crises. Engle and Granger's simple bivariate and Johansen's multivariate cointegrations are applied to the FX rates for the 1994 Mexican, 1997 Asian, 1998 Russian, and 1999 Brazilian crises. In addition, the article conducts the Granger causality test and impulse response analysis to examine the causality pattern in all the FX rates. The analysis shows most of the pre-Mexican causality disappears and significant numbers of new causality emerge in the 1994 Mexican crisis while the 1997 Asian crisis generates significant spillover effects into the later part of the 1998 Russian and 1999 Brazilian crises.
