Indirect taxes on transportation activities that pollute can correct externalities and close the gaps between private and social costs. However, policy makers often find such Pigou taxes difficult to implement because of political resistance due to possibly adverse affects on equity. For this reason it is important to assess the distributional aspects of environmental levies. This article estimates properties of the demand for transportation in parametric and non-parametric analyses of Consumer Expenditure Surveys for the United States and finds patterns in the resulting set of Engel curves. Private transportation using air flights and new cars has Engel elasticity above unity while public transportation via mass transit has Engel elasticity below unity. The findings can be interpreted in an important way since they show that a differentiated scheme of environmental taxes on transportation may function progressively. A Pigou scheme with larger taxes on modes of transportation that pollute more appears to coincide with larger levies on luxury modes preferred by richer households. 相似文献

Several papers have documented spurious welfare reversals: incomplete-markets economy produces a higher level of welfare than the complete-markets economy. This paper first demonstrates how conventional linearization can generate approximation errors that can result in welfare reversals. Using a two-country production economy, we argue that spurious welfare reversals are not only possible but also plausible under reasonable values for model parameters. This paper then proposes an approximation method that modifies the conventional linearization by a bias correction. This method can be easily implemented and approximates welfare as accurately as a second-order perturbation method. 相似文献

浙江省区域物流增量与GDP增量关系的计量分析 总被引:8,自引:0,他引:8
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。 相似文献

The aim of the present report is to review research demonstrating the role played by expectations for observed illusory price
increases after the euro introduction in Germany. In laboratory experiments when participants are asked to estimate price
changes in a restaurant following the euro introduction, the price estimates are found to be biased in the direction of the
expectation of rising prices. The research also examines the extent to which a similar judgment bias is evident in other areas
and how interventions counteract the bias. A further focus of the research is on the underlying process. In this respect the
results show that the bias is based on a selective outcome correction process not previously described. Theoretical implications
and practical implications for consumer policy issues are highlighted.

对外贸易与经济增长关系的实证分析--以山东省为例 总被引:9,自引:0,他引:9
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。 相似文献

理清中国的利率、投资、储蓄和货币供给量四个宏观经济指标之间的关系,对我国进行有效的调控具有很重要的意义。对以上四个指标进行协整和误差修正分析,判断它们的长期和短期关系。结果显示:从长期来看,这四个宏观经济变量存在很强的协整关系,且在短期范围内,这种关系对利率短期波动的影响是显著的。 相似文献

中国农村居民人均收入和城镇居民人均收入的关系,反映了中国乡镇经济的基本特征。运用协整分析方法和误差修正模型理论,对1978—2010年全国农村居民人均收入和城镇居民人均收入的年度数据进行实证分析,分析结果表明,中国农村居民人均收入和城镇居民人均收入之间存在着一个长期稳定的均衡关系,并且建立协整模型和误差修正模型,采用Granger因果检验,得出城镇居民人均收入是农村居民人均收入的原因,并从研究结论中提出针对性的建议。 相似文献

Recent episodes of housing bubbles, which occurred in several economies after the burst of the United States housing market, suggest studying the evolution of housing prices from a global perspective. We utilise a theoretical model for the purposes of this contribution, which identifies the main drivers of housing price appreciation, such as, for example, income, residential investment, financial elements, fiscal policy and demographics. In a second stage of our analysis, we test our theoretical hypothesis by means of a sample of 18 OECD countries from 1970 to 2011. We employ the vector error correction econometric technique in terms of our empirical analysis, which permits us to model the long-run equilibrium relationship and the short-run dynamics, which also helps to account for endogeneity and reverse causality problems. 相似文献

国内原油长输管道交接计量大多采用大口径容积式流量计。尽管容积式流量计误差可控制在±0.2%以内,但受制造工艺和使用条件,以及流量计检定工况与交接工况的差异、油品物性参数变化等因素的影响,流量计的计量误差有时较大。以交接计量油量计算实例,探讨采用流量计系数修正的方法,降低容积式流量计的计量误差。 相似文献
