This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour. 相似文献

Using theoretical and empirical analyses, this paper shows that the expectation dynamics induced by information asymmetry between the Central Bank (CB) and the public can cause the price puzzle. The signalling and learning dynamics between the CB and a representative private-sector agent under asymmetric information is investigated. Inflation positively reacts to contractionary monetary policy because the change in the interest rate is perceived as a signal of the CB’s private information about higher future inflation and output by the public. The empirical section of the paper validates this theoretical argument using a VAR specification about the US economy. Besides providing an explanation for the price puzzle, the results of this paper has practical implications about transparency and monetary policy. The theoretical and empirical findings indicate that asymmetric information causes significant frictions in the transmission mechanism of monetary policy. These frictions induce short-run undesired effects like increase in expected inflation and actual inflation as a response to contractionary monetary policy which is identified as “the price puzzle”. 相似文献

本文利用我国1990~2010年28个省区数据,运用VAR模型验证了省级公共基础设施投资对私人投资、就业和产出的影响,同时根据每个省区相对经济份额测算了公共基础设施投资效应的省际分布。实证结果表明:公共基础设施投资对多数地区的经济活动有促进作用;从全国范围看,区域内公共基础设施投资的直接作用远大于区域外公共基础设施投资的溢出效应;公共基础设施投资效应在地区间相对分布并不均衡,东部地区受益较多,中西部地区受益较少。 相似文献

从理论上看,现代互联网的发展和教育投入对产业升级的重要性显而易见。论文利用中国68个大中城市的面板数据,通过面板计量模型进行了实证研究,结论是:互联网发展与产业结构优化之间呈显著的正相关关系,教育投入对产业升级的影响很小;产业升级具备一定的刚性,对下一期有显著影响;教育投入能提升二三产业的就业比重,互联网的投入能显著提高霍夫曼比率,促进产业升级;产业结构提升和互联网发展都能显著促进教育的投入,产业结构优化也能带动互联网发展;短期来看,互联网发展更能影响产业结构提升,互联网的外部扩散效应以及对教育和经济的拉动辐射效应比较明显。 相似文献

基于VAR的RAROC指标评估证券投资基金绩效——实证分析 总被引:1,自引:0,他引:1
秉承风险调整收益的理念,将基于VAR构建的RAROC指标用于中国的基金业。在实证过程中对所涉及的相关指标和基金收益率的分布形态等分别进行计算和检验,主要结论是,基金投资组合的非系统性风险没有充分化解;大多数的基金收益率分布形态呈尖峰和右偏,不严格服从正态分布。 相似文献

Various structural characteristics of economies, directly or indirectly, affect the transmission from government stimuli to economic activity and determine the size of fiscal multipliers. In this article, we expand the standard Blanchard–Perotti fiscal SVAR model by incorporating the public debt and trade openness variables to assess the influence of these structural determinants on the effectiveness of fiscal spending in three selected former Yugoslav countries – Slovenia, Croatia and Serbia. The results confirmed the main hypotheses, which state that public debt level and trade openness significantly affect the effectiveness of fiscal spending through the means of reduction in size of fiscal effects in all countries analysed. When comparing internationally, this reduction tends to be more evident in countries with a higher degree of average public debt level and trade openness. 相似文献

Abstract A 3SLS econometric model is used to estimate price elasticities of supply and demand for domestically produced and imported canned tuna in the U.S. market. In addition, a VAR model is developed to examine the relations between imports and domestically produced canned tuna. For domestically produced canned tuna, a 3SLS estimation of a structural econometric model yielded a coefficient for price elasticity of supply of 0.2 and of own-price demand of ?0.3. Such price inelasticities are expected of a fishery exploited at or near its maximum yields (inelastic supply), and a consumer product widely viewed as almost a necessity in a well-stocked pantry (inelastic demand). In addition, the model yielded a cross-price elasticity of demand with respect to the price of imported canned tuna of 0.45. Additional results include an income elasticity U.S. demand for domestically packed tuna of 0.83; a cross-price elasticity with the price of bread (a complement) of ?0.33, a cross-price elasticity for the price of ground meat (a substitute) of 0.30. With respect to imported canned tuna in the U.S. market, the corresponding elasticities estimated in the model are ?1.3 (own-price demand), 3.5 (income elasticity), ?1.2 (cross-price with the price of bread) and 2.5 (cross-price with the price of ground meat). For canned tuna company managers, the results provide useful information about the likely effects on sales that would come from their own price changes, from changes in the price of imported canned tuna, and from price changes in the markets for complementary and substitute products. They can also use our results in discussions with U.S. trade negotiators, who are frequently faced with disputes over tariffs, market access, and other trade issues. 相似文献

文章利用1990—2009年陕西省的年度样本数据,用制造业各行业生产总值的变动表示制造业结构变动,用全要素生产率表示经济增长质量,分别计算出制造业结构变动率和经济增长质量变动率。利用VAR模型分析陕西省制造业产业结构变动与经济增长质量之间的关系,研究表明:制造业的变动与经济增长质量之间存在一种稳定的长期关系;制造业产业产业结构的变动和经济增长质量之间为双向的Granger因果关系;制造业产业的变动对经济增长质量存在滞后的正向冲击作用,且在一定程度上提高了经济增长的质量。文章依据研究结果给出了相应的对策建议。 相似文献

本文基于1998年1月~2018年9月的月度数据,使用VAR模型研究了目前中国利率传导的状态,发现相对于货币供应,市场利率对宏观经济变量的解释力更强,利率已经是中国货币政策传导的重要渠道。同时,利率传导的敏感度与速度在货币-证券市场之间、证券-信贷市场之间都比较高,信贷市场的利率对货币市场的利率有单向影响;但是利率通过信贷市场向消费的传导存在阻滞,向产出和投资的传导效率在不断提高。 相似文献

中国饲料工业期货的价格发现实证研究 总被引:3,自引:0,他引:3
刘晓宇 《中央财经大学学报》2006,(11):43-47
本文借助向量自回归模型、协整检验、误差修正模型、方差分解、脉冲响应函数等方法,以中国唯一的饲料工业期货———大连商品交易所豆粕期货品种为例,研究了期货价格与现货价格之间的动态关系,定量刻画了期货市场在价格发现中的作用。研究结果显示:豆粕期货价格与现货价格存在相互引导关系,并且期货与现货价格之间存在长期均衡关系,对豆粕期货来说,期货市场在价格发现功能中起到主导作用。 相似文献
