通货膨胀目标区与非线性泰勒法则

本文采用STR、TV-STR模型,利用1991年1月至2010年3月的月度数据分析了我国货币政策反应函数,与现有中国货币政策反应函数的文献相比主要有以下几个结论:第一,我国货币政策反应函数存在着结构变化,先是在1997年11月突变,然后存在一个渐变过程.第二,1997年11月前后相应存在着两个通货膨胀目标区,分别为[14.109,16.123]和[0.985,2.902],且后一通货膨胀目标区要比前一通货膨胀目标区合理.第三,随着时间推移,我国货币政策反应函数的产出缺口反应系数,逐渐由负转正,利率平滑系数则逐渐变小,这反应了随着我国利率市场化的推进,我国的货币政策操作开始越来越多的使用利率这一价格工具.     

泰勒规则在中国的协整检验

本文在全面分析泰勒规则的理论含义和实际应用的基础上 ,运用协整分析方法估计我国泰勒规则的具体形式。检验结果表明 ,泰勒规则可以恰当地描述我国银行间拆借利率的具体走势 ,并充当央行货币政策的决策依据。考虑到货币政策的时滞问题 ,本文尝试引入前瞻性泰勒规则 ,用预期通货膨胀率缺口代替原有的通货膨胀率缺口作为估计变量 ,对泰勒规则作进一步修正     

货币需求稳定性、货币目标制与中国货币政策框架改革

稳定的货币需求是货币目标制有效发挥作用的前提条件。文章首先从理论上阐述了货币需求与货币目标制的内在关联。其次,基于协整理论与误差修正模型,利用1996-2011年季度数据实证检验了中国货币需求函数的稳定性。实证研究结果表明,中国长期货币需求函数和短期货币需求函数的系数都缺乏稳定性。货币需求函数的不稳定势必增加中国以货币供应量为中间目标的货币政策操作难度,从而导致现行货币目标制的有效性和适宜性不断降低。最后提出为提高货币政策框架的有效性,中国应择机引入通胀目标制。     

Stabilising Taylor rules when the supply shock has a unit root

This paper studies the implication of unit root supply shocks for the Taylor rule. I find that, when supply shocks have a unit root, if a central bank wishes to guarantee the stationarity of inflation, then their interest rate reaction function should not respond to the output gap. Once the stationarity of inflation is guaranteed by the output-gap-response parameter, the “Taylor principle” can be applied for warranting determinacy of the dynamics.     

泰勒规则及其在中国货币政策中的检验

本文运用历史分析法和反应函数法首次将中国货币政策运用于检验泰勒规则。通过计算中国货币政策中利率的泰勒规则值 ,并与其实际值进行比较表明 ,泰勒规则可以很好地衡量中国货币政策 ,利率规则值与实际值的偏离之处恰恰是政策操作滞后于经济形势发展之时。这表明泰勒规则能够为中国货币政策提供一个参照尺度 ,衡量货币政策的松紧。对中国货币政策的反应函数GMM估计表明 ,通胀率对利率的调整系数小于 1 ,这是一种不稳定的货币政策规则 ,在这一制度下 ,通货膨胀或通货紧缩的产生和发展有着自我实现机制。     

Understanding the deviation of Australian policy rate from the Taylor rule

This investigation aims to explain and quantify the deviations of the Australian policy rate (set by Reserve Bank of Australia) from the Taylor Rule. A three-step econometric procedure designed to reflect the data-rich environment in which central banks operate is proposed using information for 229 macroeconomic series. This procedure can be applied to data for any economy with inflation targeting monetary rule. Our application with Australian data shows that approximately 65% of Australia’s policy rate deviation from the Taylor Rule can be explained systematically, with international factors and a domestic factor accounting for 41.9% and 22.5%, respectively, of the total variation in deviation from the rule.     

Comparing monetary policy reaction functions: ECB versus Bundesbank

This paper compares the European Central Bank’s (ECB) conduct of monetary policy with that of the Bundesbank. Estimated monetary policy reaction functions show that the ECB reacts similarly to expected inflation but significantly stronger to the output gap than the Bundesbank did. Theoretical considerations suggest that this stronger response to the output gap may rather be due to a higher interest rate sensitivity of the German output gap than to a higher weight given to output stabilisation in the objective function of the ECB. Counterfactual simulations based on the estimated interest rate reaction functions reveal that German interest rates would not have been lower under a hypothetical Bundesbank regime after 1999. However, this conclusion crucially depends on the assumption of an unchanged long-run real interest rate for the EMU period and is reversed when the Bundesbank reaction function is adjusted for the lower long-run real interest rate estimated for the ECB regime.

China’s monetary policy: Quantity versus price rules

Two monetary policy rules, the money supply (quantity) rule and interest rate (price) rule, are explored for China in a dynamic stochastic general equilibrium model. The empirical results seem to indicate that the price rule is likely to be more effective in managing the macroeconomy than the quantity rule, favoring the government’s intention of liberalizing interest rates and making a more active use of the price instrument. Moreover, the economy would have experienced less fluctuations had interest rate responded more aggressively to inflation.     

基于标准泰勒规则的我国货币市场利率偏离估算

本文利用泰勒规则方法对我国货币市场利率偏离程度进行了估算。对我国货币政策反应函数的经验分析表明,我国货币政策并不符合稳定货币政策规则要求。标准泰勒规则具有良好的稳健性。根据泰勒规则原式及稳定货币政策规则最低条件计算结果表明,我国货币市场利率长期存在负的利率缺口,货币政策对通胀和产出缺口并不是稳定的,更不是最优的,货币政策存在着长期偏误。这对进一步理解我国的通货膨胀和宏观经济波动,合理评价货币政策,提供了新的视角。     

An empirical evaluation of China’s monetary policies

This paper investigates the responsiveness of the Chinese government’s monetary policies in terms of the money supply and interest rates to economic conditions and the effectiveness of these policies in achieving the goals of stimulating economic growth and controlling inflation. We analyze the responsiveness and effectiveness by estimating the Taylor rule, the McCallum rule, and a vector autoregressive model using quarterly data in the period of 1992-2009. The results show that, overall, the monetary policy variables respond to economic growth and the inflation rate, but the magnitudes of the responses are much weaker than those observed in market economies. Money supply responded actively to both the inflation rate and the real output and had certain effects on the future inflation rates and real output. The official interest rates, on the other hand, responded passively to the inflation rate and did not respond to the real output. They do not have any effect on future inflation rates and real output either.     

Interest rate rules, inflation and the Taylor principle: an analytical exploration

Summary. The purpose of this article is to characterize optimal interest rate rules in the framework of a dynamic stochastic general equilibrium model, and notably to scrutinize the “Taylor principle”, according to which the nominal interest rate should respond more than one for one to inflation. This model yields explicit solutions for the optimal rule. We find that the elasticity of response depends on numerous factors, such as the degree of price rigidity, the autocorrelation of the underlying shocks, or which measure of inflation is used. In general the optimal elasticity of the interest rate with respect to inflation needs not be greater than one.Received: 6 November 2003, Revised: 17 August 2004 JEL Classification Numbers: E5, E52, E58.J.-P.

Monetary policy inertia reconsidered: Evidence from endogenous interest rate trajectory

By finding small forecastable variability of future policy rates by highly smoothed central bank's endogenous interest rate trajectory, I suggest that market's failure to predict large portion of variability in future rates does not always imply limited policy inertia.     

泰勒规则与我国货币政策反应函数——基于潜在产出、自然利率与均衡汇率的研究

潜在产出、自然利率和均衡汇率是货币政策决策和效果评价的重要参考基准。通过状态空间模型对我国潜在产出、自然利率和均衡汇率水平进行联合估计,并在此基础上通过建立一个包含汇率因素的"混合型"泰勒规则对我国货币政策反应函数进行估计,结果显示,我国货币政策行为对通货膨胀、产出缺口和汇率波动作出了较为及时和稳定的反应,但货币政策的前瞻性有待提高。     

Price expectations, capital accumulation and employment: Lindahl's macroeconomics from the 1920s to the 1950s

Erik Lindahl's approach to macroeconomics focused on the non-neutralityof monetary policy (in the short and the long run) and on thedenial of the existence of natural rates of interest and unemployment.From the 1920s until his death in 1960, Lindahl advocated theuse of norms for monetary policy to fight inflation and deflationprecisely because he would not rely on the market system's returnto natural rates. Making use of hitherto unexplored material,this paper analyses the development of Lindahl's thinking aboutprice level changes, investment and employment from the 1920sto the 1950s.     

通货膨胀目标制度在我国实施的可行性分析

20世纪90年代以来,由于通货膨胀目标制(Inflation Targeting,以下又简称通胀目标制)被越来越多的国家采用,使得通胀目标制成为近年西方货币经济学领域最热门的研究课题之一。从传统的以控制货币供应量为主的货币目标法(Monetary'Targeting)和以稳定汇率为主的汇率目标法(Exchange rate Targeting)到明确公布通货膨胀目标的通胀目标制是一个货币政策方面的重大转变。本文主要分析了我国实施通胀目标制的可行性,并提供相关的政策建议。     

The dynamic effectiveness of monetary policy in China: evidence from a TVP-SV-FAVAR model

We use a broad set of China’s macroeconomic indicators and a dynamic factor model to estimate latent factors of economic output and inflation, which are used to measure the ultimate objectives of monetary policy. The above factors and policy variables are incorporated into a TVP-SV-FAVAR model to investigate the dynamic effectiveness of Chinese monetary policy. Our results confirm that the effects of Chinese monetary policy are time-varying. By comparing the quantity rule with the price rule, we find that the price rule is more effective in managing China’s macro-economy, especially after the financial crisis. Moreover, the results can be regarded as a division of policy rules in a way that different rules are directed at different objectives.
