Are Current Account Deficits in the OECD Countries Sustainable? Robust Evidence from Time-Series Estimators

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.     

Current account sustainability in Latin America

This paper examines the sustainability of the current account deficit in eighteen Latin American countries through the analysis of the stationarity properties of the current account balance. First, we apply traditional unit root tests and consider the possibility of structural breaks. Second, since the current account may have a nonlinear behaviour, we test for linearity in the data and analyse current account stationarity by means of a recently developed nonlinear unit root test. Results from linear and nonlinear unit root tests show that current account sustainability is supported for the majority of Latin American countries with the exception of Argentina, Brazil, Chile and Paraguay. For the Dominican Republic, Honduras, Mexico, Panama, Peru, Uruguay and Venezuela the current account dynamics are best described by a stationary linear model, and by a stationary linear model with a mean shift in years 2003, 1982 and 1980 in Bolivia, Costa Rica and Nicaragua, respectively. In the case of Colombia, Ecuador, El Salvador and Guatemala, results show that the current account is best described by a mean-reverting nonlinear process.     

对外贸易与经济增长关系的实证分析--以山东省为例

对外贸易对经济增长的促进作用因不同的经济条件而有所不同。运用协整理论和误差修正模型，对山东省经济增长与对外贸易的相关性和因果关系进行实证检验的结果表明，山东省经济增长与出口和进口之间存在着长期的稳定关系，无论在短期内还是长期内，三个变量两两之间都具有显著的双向格兰杰因果关系，因此应继续坚定出口导向型的外向发展战略。     

浙江省区域物流增量与GDP增量关系的计量分析

本文首先使用Granger因果关系检验法检验浙江省1958—2004年间的物流增量和GDP增量的因果性,结果发现本省GDP增量的变化是引起物流增量变化的原因。通过协整和误差修正模型对两者的长期和短期关系进行了研究。研究发现,浙江省区域物流增量与GDP增量间存在着可靠的协整关系。这说明随着浙江经济的快速持续发展,保持两者的均衡发展具有重要的意义。最后提出基本结论以及相关政策建议。     

我国财政支出对经济增长影响的实证分析

财政支出作为财政政策的一个重要部分,对一个国家的经济发展有着重要的影响。通过对我国1990-2008年GDP以及财政支出的数据进行平稳检验和协整检验,从而建立误差修正模型,说明了我国的财政支出与经济增长存在长期稳定的均衡关系,财政支出在一定程度上促进了经济的增长。     

Remittances and FDI Effects on Economic Growth: A VECM and GIRFs for the Case of Albania

ABSTRACT

This paper analyzes the effects of remittances and foreign direct investments (FDI) on economic growth, gross fixed capital formation (GFCF), and inflation in Albania through a vector error correction model. The results show that remittances Granger-cause positively economic growth short- and long-run and negatively inflation, while no significant relationship has been established between remittances and GFCF. The findings support that remittances, apart from affecting economic growth, disinflate the Albanian economy. With respect to FDI, there are signs that inflation Granger-causes negatively FDI, while there appears to be no relationship between FDI, economic growth, and capital formation.
