Testing export-led growth in Bangladesh in a multivarate VAR framework

Although the link between trade and growth has long been discussed, systematic empirical investigation of the relationship has been undertaken only relatively recently. A number of time-series studies exist for individual countries in the area of export-led growth, but for Bangladesh there has been little work in this area. This study seeks to bridge an important gap in the literature, and is perhaps the first to use Johansen's multivariate framework taking the terms of trade as an additional variable for Bangladesh. The findings suggest that the direction of both long and short-term causality is from income to exports. This result is hardly surprising as, for most of the period covered, Bangladesh has followed an inward-looking strategy of development that discriminated against exports.     

中国货币政策数量效果的实证研究

文章主要运用了单位根检验、协整检验、格兰杰因果关系检验、脉冲响应函数和方差分解等计量经济学方法,利用1994年到2004年的季度数据,对货币供应量、利率这两个重要货币政策变量与GDP之间的关系进行了计量分析,利率对实体经济的影响不显著;不同层次的货币供应量都能对经济产生影响,但它们对GDP的作用效果是有差异的.为提高我国货币政策的效果,实现我国货币政策的目标提出了相关的政策建议.     

纺织品出口与纺织工业增长的协整关系研究

纺织工业在西方工业发达国家属于夕阳产业,中国的纺织业也面临产业结构升级的紧迫任务,但纺织业作为劳动密集型产业对于缓解中国日益严峻的就业压力具有非常重要的现实意义。纺织品出口与纺织工业经济增长之间是否存在稳定的关系,是值得关注的一个大问题。根据协整理论,利用中国1985-2004年的年度经济数据对中国纺织品出口贸易和纺织工业经济增长的关系进行实证分析。实证结果表明:纺织工业经济增长和中国纺织品出口贸易存在着比较稳定的协整关系,但是二者之间不存在因果关系,这主要是由于我国的纺织业的内需影响因素很大。     

Business Sector Production in the Short and Long Run in Israel

Engle-Granger representation theory is used to estimate the secular and cyclical determinants of business output in Israel during 1960–1988. The specification of the secular production function is based on the technique of cointegration, while the cyclical, or short-term, production function is specified in terms of an error correction model. In the preferred model of the secular production function returns to scale are slightly increasing and the productivity of Palestinian workers is approximately 40 percent of Israeli workers. In the short-term production function total factor productivity is pro-cyclical.     

Problems Existed in Applications of Cointegration Theory in China

Although the Cointegration Theory was founded by the C.W.J Granger and other economists in the 1980s, it was not widely used in China until C.W.J Granger was awarded with Nobel Prize in 2003. Since then, a lot of economic papers introducing or applying Cointegration Theory have emerged, but the phenomenon of misuse of this theory possibly arose at the same time. Based on some of these papers obtained from web site （www.cnki.net）, this paper explores the applications of Cointegration Theory in China and draws some initial conclusions. Most of these applications are reasonable, but some of them are a bit blindfold or even contradictory in conclusions, which indicates that the overall application quality has a large room to get improved and should be paid more attention by academe.     

Testing for PPP: Should we use panel methods?

A common finding in the empirical literature on the validity of purchasing power parity (PPP) is that it holds when tested for in panel data, but not in univariate (i.e. country-specific) analysis. The usual explanation for this mismatch is that panel tests for unit roots are more powerful than their univariate counterparts. In this paper we suggest an alternative explanation. Existing panel methods assume that cross-unit cointegrating relationships, that would tie the units of the panel together, are not present. Using simulations, we show that if this important underlying assumption of panel unit root tests is violated, the empirical size of the tests is substantially higher than the nominal level, and the null hypothesis of a unit root is rejected too often even when it is true. More generally, this finding warns against the automatic use of panel methods for testing for unit roots in macroeconomic time series.First version received: November 2001/Final version received : October 2003     

广西产业结构与经济增长关系的协整研究

运用协整理论对广西1978～2007年间的数据进行分析表明:广西经济增长与产业结构之间存在长期的动态均衡关系,经济增长与第二、三产业的发展相互促进,广西经济增长与第二、三产业结构之间互为双向因果关系,广西经济增长与第二、三产业产出在GDP中的比重成同向变动关系,而与第一产业产出在GDP中的比重成反向变动关系;第三产业产出对GDP的影响最大。     

江苏自主创新能力与经济增长关系的实证研究

在分析江苏自主创新现状的基础上,运用协整检验、误差修正模型和Granger因果检验等计量方法,对江苏自主创新能力与经济增长之间的关系进行了实证研究。结果表明:二者之间存在长期稳定的均衡关系,自主创新能力是江苏经济增长的Granger原因。江苏应采取相关对策,促进自主创新能力的提升。     

我国股价指数波动与宏观经济关系研究

本文以上证综合指数为研究对象,选取工业增加值、货币供应量、银行间同业拆借利率、居民消费价格指数等宏观经济变量作为解释变量,采用月度数据,对上证综合指数进行协整分析。分析证明上证综合指数与部分宏观经济变量之间存在协整关系,上证综合指数与货币供应量、同业拆借利率之间长期呈正相关关系,与居民消费价格指数负相关;并且上证综合指数与消费价格指数存在因果关系,与其他变量均不存在因果关系。这意味着我国股票市场虽然可以在一定程度上反映宏观经济的发展情况,但效率不高。     

中国电信服务省际外溢效应空间面板模型的平稳性分析

文章将针对横截面回归空间平稳性的two—stepLM检验方法拓展到空间面板情形,用以对空间面板的虚假回归和面板模型的空间单位根和空间协整进行检验,该检验的突出优点是具有灵活性和稳健性;能够将空间面板模型中单个变量空间单位根检验和整个模型的非平稳性检验统一起来,最后,文章采用two—stepLM法对我国电信服务外溢性的相关计量模型进行了空间平稳性分析。
