我国股票市场财富效应测度的实证研究

利用我国1991～2008年股票市场与居民消费的年度数据,建立股票市场财富效应模型,采用处理非平稳时间序列回归的协整理论,对股票市场对我国城镇居民消费性支出的影响作实证分析,并用误差修正模型得到因变量的短期调整。研究结果表明：随着我国经济增长和居民收入的增加,股票财富对居民消费的影响不断增强。无论从长期还是短期分析,我国股票市场的变动都会给居民消费带来财富效应。     

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.     

能源供给、能源消费与经济增长的关系——基于1978—2008年山西省数据的实证分析

本文利用1978—2008年山西省的GDP、能源供给、能源消费的数据,对山西省经济增长和能源供求之间的关系进行了实证分析。研究结果表明:山西省能源消费总量、能源供给总量均对GDP具有显著的单向Granger因果关系,山西省能源消费和能源供给一起构成了山西省经济增长的单向推动引擎;能源消费总量、能源生产总量与GDP之间存在长期协整关系。最后,提出了发展山西省能源经济及探索循环经济模式的政策建议。     

供求冲击与我国经济外部失衡——基于DSGE两国模型的模拟分析

文章为分析我国经济外部失衡问题,运用当前国际经济学领域先进的动态随机一般均衡(DSGE)两国模型研究方法,模拟了在不同消费替代弹性下以技术冲击为代表的供给冲击和以货币冲击为代表的需求冲击对一国经济外部失衡的影响。研究结果表明这两种冲击发生后该国的外部资产和汇率水平会从初始的0均衡状态偏离,而到最终收敛大约需要10年到15年的时间。这可以很好地解释当前我国的经济外部失衡,文章也依此提出了相应的政策建议。     

我国家庭支出阶段性、代际支出循环和消费不足

在生命周期理论、永久收入理论以及预防性储蓄理论的基础上考虑中国深刻的家庭观念,表现为代际之间在经济行为上的利他性,以及现阶段每代人基本相似的大额支出项目,提出了阶段性支出和代际支出循环的概念。并在这两个概念的基础上分析了我国家庭的收支行为以及资产价格、收入和消费率的关系,从新的视角解释了我国消费不足问题,并提出进一步的改革方向。     

大众媒体与青少年的非正常消费行为——以我国城市中学生为例

消费者社会化是个体获得与消费活动有关的知识、技能和态度的过程,而大众媒体是个体社会化最重要的影响因素之一。通过对中国城市青少年的问卷调查,以青少年对媒体广告的信任度和各类媒体接触频率为纬度,揭示了大众媒体如何对中国城市青少年社会化产生影响,而后分析大众媒体如何影响青少年的非正常消费倾向。研究结论为营销管理者利用大众媒体广告强化青少年的顾客忠诚度提供了理论依据。     

Diversity, persistence and chaos in consumption patterns

In this paper we present a model from which discretionary consumption dynamics can be analyzed as global properties emerging from the endogenous transformation of a society inhabited by boundedly rational interactive consumers. By considering local and global interactions among consumers, we show that behavioral diversity plays a central role in the evolution of consumption patterns. The analysis of the model reveals the existence of a regime characterized by the persistence of different social standards, and a time evolution of the social distribution of behavioral patterns towards a heteroclinic cycle. In some cases the evolution seems to be chaotic, generating unpredictable, erratic dynamics of the aggregate social indices (average or social propensity for discretionary consumption).      

Using inverted Engel curves to estimate material standards of living in a household

This article demonstrates how to estimate latent total consumption expenditure or material standard of living in households by inverting estimated Engel curves. While the conventional estimator, total purchase expenditure, is unbiased for latent total household consumption expenditure, it is not variance minimizing since it is an un-weighted sum. In two stages, this article derives a variance-minimizing, unbiased estimator by first estimating and inverting Engel curves; then combining the estimators from the inverted Engel curves. The employed latent variable method allows for utilization of non-expenditure relations. The suggested method may help improve the accuracy in studies of consumption inequality and tax evasion.      

医疗机构从零售药店购进药品所涉及的法律问题

目的：理清医疗机构从零售药店购进药品所涉及的相关法律问题,为正确适用法律提供参考。方法：案例研究、探索性的逻辑分析和法条分析方法。结果与结论：医疗机构从零售药店购进药品不具有违法性,不需要承担法律责任。零售药店在医疗机构要求的情况下,向医疗机构销售少量药品,也不具有违法性,不应当进行处罚。这一结论也适用于零售药店从其他零售药店购进药品的处理。
