关税、货币政策与中国实际均衡汇率

加入WTO后 ,降低进口品关税等措施将影响人民币均衡汇率水平 ,同时开放经济下国内货币政策、财政政策等宏观经济政策调整也会改变均衡汇率水平。本文运用动态一般均衡的方法 ,探讨中国在加入世界贸易组织之后 ,关税税率调整、货币供应量增长率改变、财政政策调整等措施对实际均衡汇率的长期效应。把货币引入生产函数和消费者的效用函数 ,我们扩展了由Turnovsky提出的两商品资本积累模型 ,利用参数赋值(calibration)的方法进行了均衡状态下的比较静态分析。研究发现降低进口品关税使人民币面临贬值压力 ,而政府增加税收 ,减少对贸易品的消费则有利于人民币的保值和升值。实证研究结果表明 :国外实际利率水平下降 ,实际货币供应量增长率降低都将引起人民币均衡汇率贬值。     

Fiscal Policy, Monetary Policy and the Exchange Rate

Domestic fiscal and monetary policy settings can influence the strength of the Australia dollar in a number of different ways.     

Time Inconsistency and the Exchange Rate Channel of Monetary Policy

This paper analyses time–inconsistency problems related to the exchange rate channel of monetary policy. Within a simple open–economy macroeconomic model, where the exchange rate is the only forward–looking variable, we show that a difference emerges between optimal policy under discretion and under commitment. Moreover, the nature of the time–inconsistency problem resembles that resulting from standard New Keynesian models: when cost–push shocks occur, the exchange rate channel gives rise to excessive output stabilisation and insufficient inertia in monetary policy under a discretionary policy.

Monetary Shocks and Real Exchange Rate Dynamics: a Reappraisal

This paper proposes a two‐country general‐equilibrium model incorporating a tradable sector with pricing‐to‐market as well as a nontradable sector. In that case, real exchange rate fluctuations arise from two sources: changes in the relative price of traded goods, that exemplify deviations from the law of one price, and movements in the relative price of traded to nontraded goods across countries. Our framework sheds light on the propagation mechanisms through which monetary shocks affect the real exchange rate. More specifically, the two components respond in opposite directions to monetary disturbances, which is consistent with data. Besides, the introduction of nontraded goods does not alter the predictive power of monetary shocks because the presence of nontraded goods magnifies the response of the deviation from the law of one price.     

The Role of the Natural Rate of Interest in Monetary Policy

This paper examines the role of the natural rate of interestin the conduct of monetary policy. The natural rate figuresprominently in many theories of the business cycle and of inflationfluctuations, and therefore has the potential to play a keyrole in monetary policy given the current mandates of many centralbanks. However, the presence of financial imperfections andmeasurement uncertainty draw into question whether estimatesof the natural rate can be reliable indicators of excess demandpressures. Natural rate-based theories may, nonetheless, provideuseful guidance in the formulation of desirable monetary policies.(JELE21, E31, E43, E58)     

我国货币政策与人民币汇率的互动关系研究

基于SVAR模型研究我国货币政策与人民币汇率的相互作用关系,发现我国货币政策对汇率冲击的反应具有逆经济风向的操作特征,汇率升值,货币政策扩张;而人民币汇率对货币政策冲击的反应也符合经济理论,货币政策扩张会引起人民币汇率贬值。同时,在货币供应量作为货币政策变量时,汇率水平的反应表现为经典的超调现象,但在名义利率作为货币政策变量时,汇率的反应曲线则表现为延迟的超调现象。总体上,我国货币政策对人民币汇率变动非常敏感,相反人民币汇率对货币政策的反应相对较弱。     

Monetary Policy and Exchange Rate Volatility in a Small Open Economy

We lay out a small open economy version of the Calvo sticky price model, and show how the equilibrium dynamics can be reduced to a simple representation in domestic inflation and the output gap. We use the resulting framework to analyse the macroeconomic implications of three alternative rule-based policy regimes for the small open economy: domestic inflation and CPI-based Taylor rules, and an exchange rate peg. We show that a key difference among these regimes lies in the relative amount of exchange rate volatility that they entail. We also discuss a special case for which domestic inflation targeting constitutes the optimal policy, and where a simple second order approximation to the utility of the representative consumer can be derived and used to evaluate the welfare losses associated with the suboptimal rules.     

我国汇率政策对货币政策的制约性分析

自2005年7月21日我国实施汇率制度改革以来,我国继续出现贸易、资本双顺差,外汇储备持续高速增加使人民币升值压力继续存在。国外游资的大量涌入,使得我国银行体系出现“流动性过剩”,并凸显通货膨胀压力。央行采取了一系列货币政策措施,包括提高利率、提高法定准备金率、发行央行定向票据等,但是效果并不明显,目前我国流动性过剩问题依然严重,通胀压力仍然存在,货币政策的实施效果严重受到了汇率政策的制约。     

当前汇率制度下中国的货币政策效应分析

在中国当前的汇率制度下,外汇储备持续增加,使得基础货币投放量被动增加,进而导致了经济中流动性过剩问题.提高货币政策独立性的根本途径在于汇率制度改革:完善中国汇率形成的市场机制,培育相对均衡汇率;深化中国外汇管理体制改革,有序开放资本市场;汇率制度改革要与其他政策改革配合协调.     

Money,Interest Rate and Foreign Exchange Rate As Indicator Variables Of Monetary Policy

Since monetary policy operations affect the ultimate targets such as real income and prices with considerable time lags, this papers attempts to identify the indicator variable of monetary policy in Korea by using autoregression tests, variance docompositions of VAR forecasts and cointegration analyses. The results show that in Korea unlike the U.S., a broad concept of money, interest rate and foreign exchange rate, taken together, could serve as the indicator variables. In particular, M3, But not M2 nor MCT, is significantly related to real income both in the short-run and in the long-run. Such a finding rejects the practice of controlling either M2 or MCT which the Korean monetary authority had exercised before implementing the recent IMF financial-reform program. [E5]     

An Analysis of Recent Changes in the Australian Exchange Rate: Nominal and Real

Recent movements in the Trade Weighted Indexes (MI) of Australia's nominal and real exchange rates are documented. The volatility of the nominal rate in the pre-float and post-float periods is examined. Decompositions are made of the most recent depreciations of the Twls into compenents due to depreciations against the United States dollar ($US) and other major currencies. The extent to which the recent changes can be understood as necessary to correct misalignment in the Australian balance of payments is investigated.     

真实汇率与真实利率差异——基于人民币真实汇率的实证研究

本文详细考察了人民币对美元、日元、港币和欧元的双边真实汇率、真实利率差异与进出口之间的统计关系，结果发现：（1）人民币真实汇率与真实利率差异间不存在显著且稳定的统计关系；（2）人民币真实汇率具有较强的“自回归”性，并且存在比较明显的非线性动态调整特征。因此，研究人民币真实汇率自身的特定生成机制可能更具有重要意义。     

Monetary Shocks and Real Exchange Rate Hysteresis: Evidence from the G-7 Countries

Long-run monetary neutrality specifies that nominal disturbances do not affect long-run real exchange rates. However, the over depreciation of the US dollar in the late 1980s, after its strong appreciation earlier in the decade, suggested to a number of observers that nominal disturbances alter long-run real exchange rates; that is, money supply shocks entail real exchange rate hysteresis. Using data from the G-7 countries and the post-1973 float, the paper measures the long-run effects of relative money supply disturbances on real US dollar exchange rates. Little evidence of hysteretic monetary policy effects is found.     

我国货币政策对人民币汇率影响的实证研究

文章基于2005年7月21日我国人民币汇率改革以来的连续时间序列数据和离散数据,利用多元回归模型,实证研究了人民币汇率市场化改革以来我国货币政策对人民币汇率的影响。实证结果表明:我国货币政策的两个变量—货币供应量和利率,会对人民币汇率产生显著的影响,其中人民币货币供应量增加会引起人民币汇率贬值,银行间信用隔夜拆借利率上升可以引起人民币汇率升值。因此,中国在稳步推进人民币汇率制度改革同时,应有效监控我国货币供应量对汇率的影响,密切关注银行间同业拆解利率对人民币汇率波动的影响,从而促进我国经济内外平衡和外汇市场的平稳健康发展。     

从汇率政策工具使用角度看我国货币政策失效的原因

自1994年我国实行双重汇率并轨开始,人民币汇率就一直保持稳定。汇率的稳定使我国货币政策效果不明显,其原因在于汇率政策工具没有得到有效的使用,汇率缺乏弹性,为此,应该有效地使用汇率政策工具。     

Real Effects of Monetary Policy in New Zealand

This article analyses the dynamic effects of unexpected domestic and foreign monetary policy shocks on industrial output in New Zealand based on a new open economy macroeconomic model. Empirical analyses are performed using unrestricted recursive open economy vector autoregressive models involving policy and non‐policy variables for New Zealand and four of its most important trading partners (that is, Australia, Japan, the United Kingdom and the United States). The empirical findings are in accord with the qualitative predictions of the conventional monetary transmission mechanism applicable to a small open economy. Consequently, no empirical anomalies are observed in the dynamic behaviour of New Zealand industrial output in response to restrictive monetary innovations of domestic and foreign origin.     

汇率波动、货币政策传导渠道及有效性——兼论"不可能三角"在我国的适用性

本文尝试把人民币汇率波动纳入货币政策中介目标监控体系,采用1996年1季度至2008年2季度的季度数据进行实证检验。研究表明:(1)我国货币政策是通过货币渠道来影响实际经济总量的,并且狭义货币供应量更能实现对实际产出目标的传导和调控;(2)人民币汇率波动的扩大会减少货币供应量;(3)不可能三角在我国是成立的;(4)将人民币汇率波动纳入货币政策中介目标监控体系能提高货币政策的有效性。     

货币政策与房地产周期性波动

基于国房景气指数的周期成分构建MS模型,分析了房地产周期的特征和货币政策对房地产周期的影响。研究表明:中国房地产市场具有非线性周期波动特征,房地产周期呈现长扩张和短收缩两种状态,并且两种状态交替出现;房地产周期不仅受到自身滞后期的影响,还受到货币政策的影响,货币政策对房地产周期的影响程度要高于房地产周期自身的影响,货币供应量的影响要高于利率的影响;不同区制状态下,货币供应量和利率对房地产周期的影响存在非对称性。因此货币当局要根据房地产周期的区制状态,有针对性地选用货币政策工具进行调控以实现房地产市场的稳定发展。     

汇率制度与货币政策——发展中国家和小国经济的思考

本文中,我们将研究在资本市场对外开放及汇率固定条件下货币政策的管理机制问题。我们的目标是探讨货币政策能否在此种情况下继续独立而有效地稳定国内经济。为此,我们建议两种制度上的约束。给定这些约束,我们证明货币政策仍然有效。同时,本文讨论了此种制度选择对发展中国家和小国经济的意义。     

价格型货币政策调控中的实际利率锚

随着利率管制的基本放开,货币政策亟需由传统数量调控向以利率为主的价格调控模式转型。作为价格型货币政策调控的实际利率锚,自然利率将为中央银行政策利率的制定提供重要依据。本文以新凯恩斯一般均衡模型为基础,从自然利率的三层含义出发,构建状态空间模型,对中国的自然利率进行估算。结果显示,我国自然利率在一定程度上可作为经济增长的先行指标,为解释和预测经济运行态势提供依据,利率缺口不仅是经济波动的"指示器",而且可以为货币政策的制定和评价提供重要依据,这对新常态下的货币政策转型和宏观调控具有重要的参考意义。
