略论中国货币政策有效性

在界定货币政策有效性的概念基础上对中国的货币政策效果进行实证分析,进而提出提高中国货币政策有效性的对策建议。货币政策目标的实现程度是衡量货币政策有效性的标志。货币政策有效性的内涵就是货币政策具有真实效应,能够对真实经济变量产生影响。货币政策有效性就是货币政策能够在保持物价稳定、国际收支平衡的前提下促进经济增长和降低失业。     

货币中介目标的国际比较*——基于DAG SVAR模型

学术界围绕最优货币中介目标的选择,在利率、简单加总货币量、迪维西亚货币量之间争论不休。本文基于DAG SVAR模型,分别对美国、欧元区、英国的银行间隔夜拆借利率R、简单加总货币量M2、迪维西亚货币量D2对物价P、产出Y影响的相对重要性进行实证比较。结果发现,在美国,M2对Y的影响最大,R对P的影响最大;在欧元区,D2对Y的影响最大,M2对P的影响最大;在英国,M2对Y和P的影响都最大。总的来说,若货币最终目标是经济增长,则美国、英国的最优中介目标是简单加总货币量,欧元区的最优中介目标是迪维西亚货币量;若货币最终目标是物价稳定,则美国的最优中介目标是利率,欧元区、英国的最优中介目标是简单加总货币量。由此可见,对于不同的经济体或者不同的货币最终目标,最优中介目标的选择可能有所不同。本文的研究结论在一定程度上是对“利率普遍优于货币量,迪维西亚货币量普遍优于简单加总货币量”学术共识的反向补充。     

基于CC-LM模型的信贷渠道的实证分析

运用CC-LM模型,基于VAR的时间序列分析货币政策中信贷渠道的存在性及其贡献度,同时分析了货币渠道的存在性,两者综合说明信贷渠道的作用强于货币渠道,也就是说信贷渠道是主要的货币政策的传导渠道。为了增强货币政策的有效性,人民银行在监控货币指标的同时,应该更加着力监控信贷指标,特别是流向中小企业的信贷量。     

货币政策对金融生态的影响机理及实证检验——基于上市商业银行面板数据的分析

传统的货币理论忽视了货币政策对银行风险承担及金融生态的影响,文章从商业银行的微观视角出发研究了货币政策对金融生态的影响机理。理论层面,金融生态与货币政策制度供给、传导机制和有效性相互关联,货币政策则通过资产价格或估值机制、收入及现金流机制、追求收益机制、杠杆调整机制、道德风险机制和风险转移机制影响商业银行的风险承担;实证层面,构建了货币政策影响商业银行信贷投放和风险承担的数理模型,选取国有和股份制两类共12家上市商业银行2008-2013年的面板数据进行固定效应模型实证检验。结果表明,宽松货币政策导致商业银行的信贷投放规模增加、风险承担意愿增强,有利于优化金融生态,反之则反是;国有商业银行对货币政策变化更敏感,而股份制商业银行对金融生态更敏感。因此,在我国宏观经济管理中,需要货币政策与宏观审慎政策相互协调配合。     

本轮通货膨胀的货币根源分析——兼论我国央行对抗通胀的困境

通货膨胀是一种货币现象,但不同层次的货币供给对物价水平的影响程度不同,货币增加对不同商品和服务价格的影响具有非均衡性和非直接性。过高估计我国货币政策对物价的影响是不适当的,由于长期的国际收支失衡、活跃的商业银行业务创新以及全国范围内资产泡沫的出现,使得央行对货币供给的数量及流动方向无法很好控制。文章最后针对如何管理我国目前以及将来的物价水平提出了政策建议。     

Monetary union or currency competition? Currency arrangements for monetary stability in East and West

Recent events in the European Monetary System on the one hand and monetary disintegration in the former Soviet Union on the other hand have revived interest in the question of how to design and choose a monetary regime for both parts of Europe that ensures monetary stability. The objective of monetary stability can be achieved either by complete monetary union or by currency competition. Building on Hayek's ideas, I argue that both regimes are viable solutions depending on the circumstances. The paper first focuses on the misperceived benefits of flexible exchange rates, making the case for monetary union in Western Europe. However, monetary union is no alternative for Eastern Europe and the former Soviet Union. Instead currency competition could be used to retain the benefits of flexible exchange rates and to foster monetary stability at the same time.     

货币政策对房地产价格调控的非对称效应——基于STR模型

从货币政策的非对称效应的角度,运用非线性模型——STR模型,探究了中国货币政策与房地产价格的关系。研究结果表明:货币政策对房地产价格的影响确实因所处经济周期阶段的不同而发生变化;货币政策与房地产价格之间存在非线性关系;不同经济增长水平下货币政策对房地产价格的调控效应是不对称的;在调控房地产价格方面,我国货币政策的信贷传导路径比利率传导路径更有效。     

Asymmetric effects of monetary policy shocks on economic performance: empirical evidence from Turkey

This study investigates the asymmetric effects of monetary policy shocks on the macroeconomic variables of exchange rate, output and inflation for an emerging economy ? Turkey ? by using monthly data between 1990 and 2014. We employ the innovative nonlinear vector autoregressive model of Kilian and Vigfusson (2011), which allows us to observe the effect of different stances (tight or loose) and different sizes (small or large) of monetary policy actions. Our empirical evidence reveals that tight monetary policy, which, in this case, is captured with a positive shock to interest rate, decreases exchange rate, output and prices, as economic theory suggests. Loose monetary policy, which is captured with a negative shock to interest rate, has the opposite effect on these variables. However, the effects of loose monetary policy are weaker than the effects of tight monetary policy because loose monetary policy shocks are less effective than tight monetary policy shocks. Moreover, as the magnitude of a shock increases, the difference between the effects of tight and loose monetary policy policies also increases.     

我国统一调控下货币政策内部传导区域效应非对称性分析

我国外汇资产迅速扩张,外汇占款取代再贷款成为我国中央银行基础货币投放的主渠道。经济开放程度高的发达区域不仅基础货币投放量远远超过其他区域,其区域货币乘数也高于其他区域,导致货币政策内部传导的区域效应非对称性。实证分析认为,我国基础货币变化对开放程度最高的东部发达区域货币供应量的影响最大,其次是经济不发达的中部区域,对开放程度低的西部不发达区域的影响最小。建议采取适度差别的区域货币政策,缓解区域货币供给的非均衡性,提高我国货币政策内部传导的整体效率。     

我国资产价格波动与货币政策关系研究

随着金融自由化的逐步推进,资本市场存量日益增大.这既体现了金融深化程度的提高,又意味着货币供应与国民经济主要指标之间稳定性的弱化.资产价格对货币政策的制订和执行会产生深刻的影响.其中股价、房价等资产价格在货币政策传导机制中扮演的角色越来越重要.本文从实证角度出发,通过构建VAR模型检验我国资产价格对货币政策的反应以及资产价格对货币政策目标的影响,发现资产价格、货币政策及货币政策目标间存在长期协整关系,资产价格对产出有正向冲击作用,股市显著影响通货膨胀,但房地产市场对通货膨胀推动作用不明显,资产价格受货币政策的冲击影响显著,其中股市对货币政策冲击的反应明显大于房地产市场.     

Money growth,uncertainty and macroeconomic activity: a multivariate GARCH analysis

The impact uncertainty has on money growth has received much attention in recent years and is an issue of critical importance to central banks, particularly for those, such as the European Central Bank (ECB), which place a strong emphasis on monetary analysis in monetary policy formulation. Some recent papers examining this issue use ad hoc estimates and measure variability rather than uncertainty. We employ a multivariate GARCH model, which measures uncertainty by the conditional variance of the data series, to investigate whether macroeconomic uncertainty and monetary uncertainty Granger-cause changes in real money. The estimated model also allows us to investigate how monetary uncertainty impacts economic activity. We find that macroeconomic uncertainty impacts positively on US real M2 growth over a two-year horizon but that monetary uncertainty does not cause changes in real M2. Instead, our results indicate that real money growth causes monetary uncertainty. Monetary uncertainty is found to have a negative effect on real economic activity and on macroeconomic uncertainty. We conclude by discussing the implications of these results and the methodological approach used for institutions such as the ECB that give monetary analysis a prominent role in their monetary policy strategy.     

The nonlinear effects of expected and unexpected components of monetary policy on the dynamics of REIT returns

This paper examines empirically whether the expected and unexpected components of monetary policy have nonlinear impacts on the dynamics of REIT returns. Empirical results find the nonlinear response of REIT returns to expected and unexpected components of monetary policy. The unexpected component of monetary policy plays a more prominent role in influencing REIT returns than does the expected component of monetary policy. Specifically, unexpected contractionary monetary policy has a significantly adverse impact on REIT returns, and the adverse effect in a bust market is stronger than in a boom market. In addition, the unexpected monetary policy will also affect the boom-bust dynamics of REIT returns through its effect on the time-varying transition probability matrix. The tightening of the expected and unexpected components of monetary policy will enhance the probability that the REIT market will stay in the bust regime.     

资产价格的波动与货币政策

文章主要论述了资产价格和货币政策目标及传导机制之间的关系,并提出了最优的货币政策选择,最后阐述了目前我国资产价格和货币政策之间的关系。     

货币政策、金融周期及其宏观经济效应

本文综合金融市场的多维信息,利用主成分分析法合成我国的金融周期指数。在此基础上,构建TVP SV VAR模型研究2003—2017年间我国货币政策、金融周期及宏观经济变量间的时变互动关系。研究发现：（1）我国货币政策、金融周期和宏观经济变量之间存在显著的时变互动关系。（2）金融传导渠道可能扭曲货币政策效力,通过金融传导渠道,货币政策不仅会抑制经济增长,还可能加剧通货膨胀。（3）金融周期对货币政策产出效应的影响滞后于对价格效应的影响。短期来看,货币政策产出效应的时变特征与金融传导渠道无太大关联,但随时间推移,金融繁荣对产出的负面影响可能最终使货币政策产出效应发生反转。货币当局应警惕金融繁荣对货币政策效力的扭曲,审慎操作,且不宜承担过多刺激产出的任务。     

前瞻性货币政策反应函数在我国货币政策中的检验

本文在泰勒等西方学者对货币政策反应函数研究的基础上,构造一个适合我国国情的前瞻性货币政策反应函数,从市场利率(同业拆借利率)、管制利率(存贷款利率)以及两者利差三个层次,通过该反应函数对我国货币政策的实证检验结果发现,一方面,该反应函数能够很好地描述同业拆借利率、存贷款利率和两者利差的具体走势,能够为我国货币政策的制定提供一个参考尺度,以衡量货币政策的松紧。另一方面,检验结果表明,三个层次的利率对预期通胀率和预期产出的反应绝大多数都不足,这说明,我国货币政策是一种内在不稳定的货币政策。     

浅析稳健的货币政策

2011年12月举行的中共中央政治局会议定调2012年继续实行稳健的货币政策。理解稳健的货币政策,分析其实行效果已成为当务之急。归纳了稳健货币政策的演化史,分析了该货币政策的特征,并总结了其实行效果与面临的挑战。稳健货币政策的运行方式是逆向操作的相机抉择。该货币政策难以对CPI进行精确的控制,难以有效抑制经济过快发展。为提高货币政策的实施效果,央行应当增加基准利率调整频率,并减少对央行票据的依赖。     

ECB monetary policy and commodity prices

We assess the impact of ECB monetary policy on global aggregate and sectoral commodity prices over 2001–2019. We employ an SVAR model and separately assess periods before and after the global financial crisis. Our key results indicate that contractionary monetary policy shocks have positive effects on commodity prices during both conventional and unconventional monetary policy periods, indicating the effectiveness of unconventional monetary policy tools. The largest impact is documented on energy (fuel) and food commodities. Our results also suggest that the effect of ECB monetary policy on commodity prices transmits through the exchange rate channel, which influences European market demand.     

基于资产价格影响的货币政策非对称性效应研究

利用NK-SVAR模型就我国货币政策的非对称性效应进行研究,结果表明,紧缩性货币政策的效果比较明显,而扩张性货币政策效果较弱.货币冲击的紧缩效应强于扩张效应,这表明抑制经济的过快增长时紧缩性的货币政策效果显著,但扩张性货币政策无法摆脱经济的恶性衰退.

Monetary Neutrality and Optimality with Symmetric Partial Information

The neutrality and optimality of countercyclical monetary policy are examined in a representative economy featuring competitive equilibria in multiple markets and rational expectations based on a form of private information about current stochastic innovations in the economy. A necessary and sufficient condition for the neutrality of monetary policy is stated in terms of restrictions on the parameters of the linear rule describing prospective monetary feedback. Optimal monetary policy is fully characterized in terms of an alternative set of parameter restrictions. Optimal monetary feedback completely stabilizes deviations in commodity output by eliminating the influence of those current innovations about which agents cannot directly observe from the rational expectations of agents.
