Globalization, Financial Volatility and Monetary Policy

Recently it has often been claimed that globalization eases the job of central banks as it helps to tame inflation. This is used to argue that central banks (particularly the ECB, referring to the objectives as laid down in the EU Treaty) could or should reduce their efforts in the fight against inflation in favor of supporting the general economic policies of the governments. This paper takes a critical look at this argument, pointing to the structural changes associated with globalization and to the corresponding increase in uncertainty by which the central banks are affected. As an example of this, the increase in financial volatility is analyzed and explained as the result of optimal portfolio allocation, and its implications for monetary policy are discussed.     

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.     

Stabilization Effects of Narrative-based Monetary Policy in Jamaica

The study constructs a monetary policy indicator (MPI) from monetary policy documents and the actions of the Bank of Jamaica and Ministry of Finance and Economic Planning, and uses it to estimate four variants of an analytical narrative-vector error correction model (AN-VECM) with cointegration as the identifying restriction. In AN-VECMs 1 and 2, the cointegration is estimated in level form with respective short-term interest rate and the MPI as regressands. The first difference forms of respective models are re-estimated in AN-VECMs 3 and 4. The results are mixed, with AN-VECM 1 yielding the least results. However, in all cases, the impulse response functions indicate that the MPI yields slightly superior results in both AN-VECMs 2 and 4. A positive shock in the MPI produces price and exchange rate results which are consistent with a priori expectations from economic theory, and mixed liquidity effect and real output results. Thus, the MPI provides an important policy tool alternative for policymakers in small open economies to consider in the implementation of monetary policy.

货币冲击、房地产收益波动与最优货币政策选择

与传统资产定价模型中风险收益权衡关系相悖,我国房地产市场存在投资异象和波动长记忆性特征。文章利用泰勒规则(Taylor Rule)的利率缺口,在剔除市场预期之后测度了中国市场的货币政策冲击,并基于房地产投资回报的时序数据波动聚集性和时变性特征构建GARCH(1,1)-M模型,以此度量我国房地产市场投资收益的波动演变路径,解释了央行实施加息的货币政策后当期房价反而上涨的投资现象。文章还立足于房地产市场参与人的投资特征,从行为金融学的全新研究视角出发,建立包含行为资产定价的动态模型经济系统,研究资产价格波动与最优货币政策选择问题,求得相应闭型解,为实施关注资产价格波动的最优货币政策提供理论基础。     

The Effects of Foreign Currency Derivatives on the Monetary Policy Exchange Rate Channel in China

This paper examines changes in the monetary policy exchange rate channel in the presence of foreign currency derivatives (FCD) markets in China. Initially a theoretical macroeconomics model incorporating the exchange rate risk hedging is presented, and this is followed by an empirical test. A theoretical model implies that with more firms using foreign currency derivatives to hedge the exchange rate risk, the effect of the exchange rate on the net exports will be weaker and may even be reversed. The empirical section uses Structure Vector Autoregression (SVAR) models with China's monthly macro data over the 2000–2013 period to assess the impact of the FCD market on the exchange rate channel. Empirical support for the changes in the exchange rate channel transmission is found. By impulse response function (IRF) analysis, with the emergence of the domestic FCD market in China, in the long run the probability becomes higher that the negative effect of RMB appreciation on China's net exports to the US is reversed; meanwhile the negative effects of RMB appreciation on the overall net exports and the net exports to the EU become gradually weaker on average.     

Monetary Union Enlargement,Fiscal Policy,and Strategic Wage Setting*

This contribution develops a framework for studying the effects of the enlargement of a monetary union on macroeconomic performances in the presence of strategic interactions between non‐atomistic labor unions, monetary, and fiscal authorities. We show that the integration of new identical member countries may have beneficial effects, depending on the fiscal policymaking structure. Qualifications to this result are provided under cross‐country asymmetries in the size of the economies, the structure of the labor markets, and the fiscal authorities' preferences.     

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。     

存款利率上限、金融脱媒与货币政策传导

文章在DSGE框架下引入抵押贷款约束和存款利率上限,研究了存款利率上限对货币政策传导的影响.根据我国的实际情况,文章允许存款利率在规定的上限内浮动,并分析了已有文献尚未涉及的存款利率上限偶然紧的情形.研究发现:(1)当央行采取紧缩性货币政策时,存款利率上限抑制了存款利率的上升,导致存款利率偏低,家庭的银行储蓄减少,从而产生金融脱媒现象;(2)金融脱媒导致银行可贷资金减少,引起贷款供给扭曲,贷款利率大幅上升,与没有存款利率上限的情形相比,经济波动更大;(3)偶然紧的存款利率上限具有非线性性质,使主要经济变量对扩张性与紧缩性货币政策冲击的脉冲反应存在不对称性.     

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。     

当前我国"负利率"现状及货币政策选择

在当前的宏观经济形势下,我国的负利率对居民消费和储蓄、企业投资、商业银行的经营管理和资本市场等具有不同影响。综合考虑这些影响,央行目前不宜提高名义利率,而应该提高宏观经济调控水平,确保经济能够长期健康发展。     

货币政策是否应该考虑汇率目标——基于美联储加息政策的应对分析

美联储启动加息预期以来,新兴市场和发展中国家货币汇率出现了较为剧烈的波动,关于货币政策规则中考虑汇率目标的争论增多。本文使用小型开放的新凯恩斯宏观经济模型,分析了美联储货币政策冲击对我国采取不同汇率目标权重货币政策规则时的影响。研究发现,美联储加息政策将使得我国产出减少、失业增加、通胀增加、汇率贬值。随着货币政策规则中汇率目标权重的增加,国内产出下降幅度扩大、失业增加幅度扩大、通胀增加幅度缩小、汇率贬值幅度缩小。此外,货币政策规则中考虑汇率目标也进一步削弱了本国货币政策的独立性。在此基础上,本文提出,在具体的货币政策实践中,货币当局应该根据本国的实际情况,对产出、就业、通胀和汇率等宏观经济变量的重要性做出权衡。     

货币政策对产业发展的非对称性效应分析

产业发展状况关乎中国经济增长速度和发展质量。本文对货币政策的产业发展效应传导机制进行理论描述,并基于T-VAR模型对中国货币政策的产业发展效应进行实证分析,重点刻画货币政策冲击下三大产业的非线性和非对称性响应特征。研究发现:第一,中国的货币政策与产业发展之间并非简单线性关系,二者之间存在一定门限效应;第二,不同区制下,货币政策对产业发展的动态冲击呈现出明显的非对称性特征,低区制下三大产业发展受货币政策的影响强度明显大于高区制下三大产业发展受货币政策的影响强度;第三,相同区制内,同一货币政策工具对不同产业的冲击影响存在非对称性现象。因此,应结合区制差异采用不同的政策工具调控三大产业发展。

Non-stationary Interest Rate Differentials and the Role of Monetary Policy

Abstract

The present work deals with a frequently detected failure of the uncovered interest rate parity (UIP) – the absence of bivariate cointegration between domestic and foreign interest rates. We explain the non-stationarity of the interest differential via central bank reactions to exchange rate variations. Thereby, the exchange rate in levels introduces an additional stochastic trend into the system. Trivariate cointegration between the interest rates and the exchange rate accounts for the missing stationarity property of the interest differential. We apply the concept to the case of Turkey and Europe, where we can validate the theoretical considerations by multivariate time series techniques.

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.
