能源价格对能源强度和经济增长影响的CGE研究   总被引:7,自引:0,他引:7  
将能源替代模块和能源强度指标纳入中国CGE模型—MCHUGE模型,研究提高能源价格对能源强度和经济增长的影响。研究表明:提高能源价格在短期和长期均能显著降低中国能源强度,其原因是能源价格的提高优化了中国经济产业结构,第二产业尤其是重工业在GDP中所占比重下降,减少了总体的能源消费。但是能源价格提高对宏观经济带来了较大的负面影响,其导致的出口下降和投资需求下降分别是短期和长期GDP下降的主要原因。  相似文献

由于我国证券市场起步较晚,市场机制还不健全,政府经常用政策来对市场进行调控。由于政策的出台对证券市场的风险有很大的影响,所以需要对政策的传导过程进行了解和掌握。本文通过建立GARCH模型,用VaR的方法来分析我国证券市场中政策的传导效应,并提出相应的政策建议。  相似文献

金融CGE模型研究与应用   总被引:2,自引:0,他引:2  
可计算一般均衡(CGE)模型在国际贸易、环境保护和财税政策研究领域已经得到非常普遍的应用,但其在金融领域的应用却存在严重不足。金融CGE模型的发展主要受货币中性假设以及数据搜集、处理的困难等因素的制约。改进金融CGE模型,必须考虑国际金融市场和金融部门资本存量的影响并在模型中适当进行描述,同时还必须解决好中长期动态均衡问题。  相似文献

在充分吸收CGE模型优势的基础上,我们结合央行宏观经济模型特点,对二者进行有机整合,使之为宏观经济分析和货币政策决策服务。借助该模型不仅可以进行总量分析,还能进行结构分析,从而可以较全面地剖析货币政策对经济的影响过程。  相似文献

基于状态空间模型的贷币政策传导效率   总被引:2,自引:0,他引:2  
货币政策变量间的作用强度是反映传导效率的关键指标。基于以货币供给为中介的传导框架,通过构建状态空间模型来研究货币政策内、外部传导系统关键变量间的弹性及其时变情况,我们发现,不同环节传导效率的变动趋势差异性大;存款准备金是效率最高的货币政策手段;货币供应量目前仍是中国货币政策中介的最优选择;货币政策对物价的调控低效等。通过HP滤波刻画变量状态表明,货币政策传导效率与政策状态没有必然联系。  相似文献

本文通过建立向量自回归模型实证分析了我国PPI、RPI与CPI之间的价格传导关系.格兰杰因果关系表明整体上我国经济中各个环节的价格传导是顺畅的;脉冲响应函数分析得出PPI从供给方影响CPI,而CPI从需求方影响PPI,各变量之间存在着一定的时滞关系.  相似文献

以往国内利用可计算一般均衡(CGE)模型进行实证研究的文献,大多是假设中国处在资本充足、充分就业的新古典主义宏观闭合框架下,忽视了我国目前处于二元经济的客观事实。本文基于中国现阶段的基本国情,建立了一个刘易斯宏观闭合下的CGE模型,并利用该方法模拟了2008年末我国启动的政府投资(1.18万亿)对经济各个方面产生的影响。模拟结果显示:政府投资将会在未来几年之内拉动实际GDP增长1.83%、提升总消费2.1%、社会总投资9.89%、进口额2.09%、出口额2.14%,同时将带来约1805万的新增就业机会。  相似文献

This article conducts a computable general equilibrium (CGE) model to investigate the impacts of a carbon tax on economy at province levels in China since China features significantly differentiated development modes across regions. Three representative provinces including Henan, Fujian, and Chongqing are selected as the sample. The empirical results indicate that carbon tax is an efficient policy to reduce carbon emissions accompanied with negative impact on provincial economy. To cushion the negative impacts of carbon tax, a moderate carbon tax rate and carbon tax recycling policy are recommended according to the simulation results.  相似文献

本文在一般均衡世代交叠模型框架下研究了退休后劳动供给对于主要经济变量的影响。结果表明:老年人退休后劳动供给的增加会导致劳动相对于资本贬值、人均资本存量和人均产出降低、个人消费和储蓄降低、个人福利下降。由于增加退休后劳动供给和延迟退休年龄具有较强的替代关系,本文认为这一结论对于延迟退休年龄决策有一定的借鉴意义。  相似文献

以2017年投入产出表为基础,编制了社会核算矩阵,通过可计算一般均衡(CGE)模型系统地分析了在不同碳税水平下碳税征收对能源-经济-环境系统的影响,进而揭示碳税政策的实施能否实现环境保护与经济发展的双重红利效应.研究结果显示,征收碳税能够减少化石能源的消费,促进二氧化碳排放量的减少,且随着碳税水平的提高,其降碳效果更加明显.同时,征收碳税有助于产业结构转型,但对经济增长、居民消费与企业收入具有显著的负向冲击.在短期内,碳税政策无法实现降碳促增的双重红利效应.因此,为实现环境保护与经济发展的双赢局面,在实施碳税政策的同时应该辅以合理的经济政策.  相似文献

保障性住房价格是住房保障制度的重要组成部分,价格合理与否不仅关系到住房保障政策的实施效果,而且还是住房保障政策可持续发展的前提.从理论上看,保障性住房价格机制包括价格形成和价格运行机制,二者相互影响、相互制约而又相互促进.当前,我国保障性住房价格形成机制和运行机制都存在一些亟待解决的问题.本文在分析保障性住房价格形成机制、运行机制的基础上,构建一个科学合理的能指导住房保障工作实践的价格机制.  相似文献

This paper examines the contribution of market expectations to commodity price dynamics. It proposes a dynamic competitive storage framework with an explicit expectations shock along with concurrent shocks to study the commodity price movements. This allows for a refined analysis of the expectations’ effect on price and inventory and the estimation of the expectations. Applied to the world crude oil market, it finds that the contribution of market expectations to the crude oil spot price movements is limited from 1987 to 2014.  相似文献

The author proposes a new single-stock generalization of the Black-Scholes model. The stock price process is Markovian, the volatility is time-varying, and the market is complete. We also consider the option pricing based on our model and a connection with the equilibrium theory.  相似文献

This article analyzes the dynamic process of price discovery in a competitive securities market where investors are equally informed about the fundamental determinants of an asset's end-of-period value but, because they do not know each other's wealth positions, do not know the equilibrium price of shares at the start of a current trading session. Because a large number of participants is assumed, issues concerning market impact and market manipulation are avoided. As trading progresses, participants update their expectations of an asset's equilibrium value. As they do so, price can either converge to a new level or, following a run, revert back to a previous level. This implies that, in clusters of adjacent prices, price changes are more apt to be predominantly of like sign (positive or negative) than would be the case under random walk with a bid-ask spread. Moreover, reversals, when they do occur, should be larger than continuations. An examination of 1988 transactions data for the 30 Dow Jones Industrial stocks shows that this is indeed the case. With the effect of the bid-ask spread removed, first-order autocorrelation coefficients are found to be positive.  相似文献

A switch from the current destination-based value-added taxation to an origin-based consumption tax will not be neutral in a world economy with international capital mobility and overlapping generations. This paper evaluates the macroeconomic and welfare effects of such a multilateral reform in a two-region, intertemporal general equilibrium model. The analysis isolates and quantifies income effects due to changes in generations' tax burdens, factor price repercussions and initial asset price adjustments, as well as efficiency effects that arise from endogenous labor supply and short run savings responses in a numerical simulation exercise.  相似文献

This article presents and extends the first known model in real options, proposed in Tourinho (1979), and provides thoughts on addressing issues that are still outstanding 30 years later. It discusses the need to ensure the existence of market equilibrium when applying real options valuation to price assets, once all agents behave as suggested by the solution to the pricing equation. It argues that this can be achieved by using a stochastic process for the price that is sufficiently general to respond to supply and demand imbalances in the market for the resource. Once the individual decision rules are derived, the parameters of the process must be determined to ensure market equilibrium exists. For reserves of natural resources, this can be done by using a mean-reverting process for the price of the commodity and ensuring that the long-term price to which it reverts equals the trigger price for development of the marginal reserve.  相似文献
