Financial market imperfections and monetary policy strategy

In a model with imperfect money, credit and reserve markets, we examine if an inflation-targeting central bank applying the funds rate operating procedure to indirectly control market interest rates also needs a monetary aggregate as policy instrument. We show that if private agents use information extracted from money and financial markets to form inflation expectations and if interest rate pass-through is incomplete, the central bank can use a narrow monetary aggregate and the discount interest rate as independent and complementary policy instruments to reinforce the credibility of its announcements and the role of inflation target as a nominal anchor for inflation expectations. This study shows how a monetary policy strategy combining inflation targeting and monetary targeting can be conceived to guarantee macroeconomic stability and the credibility of monetary policy. Friedman's k-percent money growth rule, which can generate dynamic instability, and two alternative stabilizing feedback monetary targeting rules are examined.     

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.     

An inventory of simple monetary policy rules in a New Keynesian macroeconomic model

We derive necessary and sufficient conditions for simple monetary policy rules that guarantee equilibrium determinacy in the New Keynesian monetary model. Our modeling framework is derived from a fully specified optimization model that is amenable to analytical characterisation. The monetary rules analyzed are variants of the basic Taylor rules ranging from simple inflation targeting (current, forward, backward) to canonical Taylor rules with and without inertial nominal interest rates. We establish that determinacy obtains for a wide range of policy parameters, especially when the monetary authority targets output and smoothes interest rates. Contrary to other results in the literature, we do not find a case for super-inertial interest rate policy.     

The effects of the monetary policy regime shift to inflation targeting on the real interest rate in the United Kingdom

This paper studies the effects of the monetary policy regime shift to inflation targeting on the stochastic properties of the real interest rate in the U.K. The empirical analysis suggests a constant mean of the real interest rate that shifts with the monetary policy regime change to inflation targeting in October 1992. The mean-reverting level of the real interest rate has decreased from 5.1% to 2.3% per annum with the change in monetary policy to inflation targeting. In addition, the shift in monetary policy regime to inflation targeting has reduced the volatility of the real interest rate and increased the persistence of real interest rate deviations from the mean. The results suggest that the central bank can affect the stochastic properties of the real interest rate through the choice of monetary policy regime over a long period of time.     

Time-varying transmission efficiency of China’s monetary policy

This paper tries to investigate the time-varying characteristics of China’s monetary policy transmission from the impulse response evidence of both open-economy DSGE model and TVP-VAR model. We find that the transmission efficiency of price-based monetary policy has significantly improved over the sample period, while quantity-based monetary policy is weakening. The resume of exchange reform in 2010 also strengthens the exchange rate channel especially in terms of price-based monetary policy. Combining with the evidence from DSGE model underlines the importance of further interest rate liberalization and price-based monetary policy Taylor rule should also consider the exchange rate stability.     

Monetary Policy in Russia: Identifying exchange rate shocks

Russian monetary policy has failed persistently to achieve sustained low inflation, both in absolute terms and relative to the peer group of countries similarly exiting from Soviet-style central planning. This paper explores the reasons for this state of affairs by analysing the kind of monetary policy that has been pursued by the central bank during the period 1995 to 2009. Our contribution is to search for a possible transmission channel between the real interest rate, inflation rate, exchange rate, output growth and foreign reserve growth, after having controlled for the effect of oil price inflation. Using a vector autoregressive model in error-correction form and using sign restrictions methodology, we show that the monetary authorities’ failure to abate double-digit inflation appears to be driven by the policy of exchange rate targeting, as reflected in our identified exchange rate shocks.     

What is the right balance between US monetary and fiscal policy? Explorations using simulated wavelet-based optimal tracking control

This paper uses wavelet-based optimal control to simulate fiscal and monetary strategies under different levels of policy restrictions. The model applies the maximal overlap discrete wavelet transform to US quarterly GDP data and then uses the decomposed variables to build a large 80-dimensional state-space linear-quadratic tracking model. Using a political targeting design for the frequency range weights, we simulate jointly optimal fiscal and monetary policy where: (1) both fiscal and monetary policy are dually emphasized, (2) fiscal policy is unrestricted while monetary policy is restricted to achieving a steady increase in the market interest rate, (3) only monetary policy is relatively active, while fiscal spending is restricted to achieving a target growth rate, and (4) monetary policy emphasizes short-run stabilization, while fiscal policy utilizes political cycle targeting. The results show that fiscal policy must be more aggressive when the monetary authorities are not accommodating the fiscal expansion and that the dual-emphasis policy leads to a series of interest rate increases that are balanced between a steadily increasing target and a low, fixed rate. This research is the first to construct integrated fiscal and monetary policies in an applied wavelet-based optimal control setting using US data.     

基于SVAR的中国货币政策的房价传导机制

本文采用2005年7月到2009年9月宏观经济数据构建SVAR模型,分别从货币供给的利率传导机制,现金余额效应,汇率传导机制以及房地产价格对货币供给的反馈机制四个角度进行实证分析,发现:货币量的增加和汇率上升都会带来房价的大幅上涨,而利率提高所带来的房价下降程度很小,房价的上涨会引起物价和消费上涨。结论:当今房地产市场中,存在着货币政策的房价传导机制,其中利率机制对房价影响较小;在汇率机制传导过程中,中央银行为了稳定币值和升值预期引起的国际资本流入导致货币供应量被动增加,从而直接导致了房地产价格上涨。因此提出货币政策应当关注房地产价格,既要防止形成房地产价格泡沫,又要避免温水煮青蛙。     

Inflation and interest rates in the presence of a cost channel,wealth effect and agent heterogeneity

As far as the control of inflation is concerned, the interest rate is the most important monetary instrument. This paper examines the effectiveness of the interest rate policy in controlling inflation. The model utilized in this paper considers both demand and supply side effects of interest rate policy. These effects are used to derive not only the relevant impulse response functions but also the welfare loss to the society that arises from the supply side shocks. Based on their ability to control inflation and minimization of the overall welfare loss to the society, three policies are compared: (i) monetary policy with commitment, (ii) Taylor's rule, and (iii) inflation targeting. We argue that, in the presence of a cost channel, it is imperative that the interest rate policy is used with restraint. Our results also suggest that ignoring the cost channel of monetary policy can lead to significant under-estimation of the social welfare loss.     

Optimal monetary policy in the presence of food price subsidies

Food price subsidies are a prevalent means by which fiscal authorities may counteract food price volatility in middle-income countries (MIC). We develop a DSGE model for a MIC that captures this key channel of a policy induced price smoothing mechanism that is different to, yet in parallel with, the classic Calvo price stickiness approach, which can have consequential effects for monetary policy. We then use the model to address how the joint fiscal and monetary policy responds to an increase in inflation driven by a food price shock can affect welfare. We show that, in the presence of credit constrained households and households with a significant share of food expenditures, a coordinated reaction of fiscal and monetary policies via subsidized price targeting can improve aggregate welfare. Subsidies smooth prices and consumption, especially for credit constrained households, which can consequently result in an interest rate reaction less intensely with subsidized price targeting compared with headline price targeting.     

中国货币政策利率传导机制有效性的实证研究

本文基于新颖的和交叉性统计数据,通过协整检验与Granger因果关系检验等方法,对中国货币政策的利率传导机制进行实证研究.实证分析结果表明:(1)我国货币政策的利率传导机制是低效的.(2)货币政策在整体上却有效.这从侧面可以证明:相比较于其他几个货币传导机制,我国的利率传导机制的阻塞效用更强,即其对货币政策总体绩效的贡献度相对最小.(3)利率传导机制还存在时滞效应.本文认为,解决目前我国利率传导机制低效性的主要方法还是要通过利率市场化的渐进推进.     

REGIONAL EFFECTS OF MONETARY POLICY IN CHINA: EVIDENCE FROM CHINA'S PROVINCES

This study examines the provincial effects of monetary policy from 1978 to 2011 in China. We used the SVAR method to measure the magnitude and timing of each province's response to monetary policy shocks when considering the influences of spillover effects among provinces. Then we also explored the regional effects of monetary policy employing multiple linear regressions. The results confirm that provinces respond differently to monetary policy actions. It was found that in the short run, the influence of spillover effects on a province's response is very important, but in the long run, the negative influence of deposit transfers overtake the positive impact of the spillover effect. For the factors causing the regional effects on monetary policy, the results show that the interest rate channel is rather weak at the regional level in China. The bank lending channel can explain the regional effects of monetary policy to some extent. Thus in China, the bank lending channel is more effective than the interest rate channel at the regional level.     

The role of the exchange rate in Canadian monetary policy: evidence from a TVP-BVAR model

A time-varying parameters Bayesian structural vector autoregression (TVP-BVAR) model with stochastic volatility is employed to characterize the monetary policy stance of the Bank of Canada (BoC) in terms of an interest rate rule linking the policy rate to the output gap, inflation and the exchange rate. Using quarterly bilateral Canadian–US data, we find such an interest rate rule to have little explanatory power for the early part of our sample starting in the mid-1980s, but to become more suitable to explain interest rate dynamics from the mid-1990s onwards. Whereas the exchange rate turns out to be the major determinant of the policy rate in the 1980s, its importance declines throughout the 1990s and 2000s, although it continues to be influential even towards the end of the sample period ending in 2015Q2. We also find interest rate shocks to have become more effective in influencing the macroeconomy over time, indicating that the BoC has continually gained monetary policy credibility. We associate this development with the BoC successively de-emphasizing the role of the exchange rate in informing interest rate decisions, thereby alleviating the potential monetary policy conflict between targeting the exchange rate and maintaining the price stability goal.     

货币政策对利率期限结构的影响——基于动态Nelson-Siegel模型的实证分析

以中国人民银行发行的央票利率为货币政策变量,以动态Nelson-Siegel模型为基础构造动态因子模型,采用卡尔曼滤波估计利率期限结构因子,与货币政策变量一起建立误差修正模型,以此分析货币政策对利率期限结构的短期动态影响和长期均衡影响;同时基于中国银行间市场债券交易数据进行的实证分析表明:货币政策和利率期限结构之间的短期动态影响表现出非对称性,即债券市场对货币政策变化的反应较为迟缓,但货币政策对市场利率的变化反应敏锐。而长期均衡关系则表明,货币政策对银行间债券市场利率期限结构有显著影响,但银行间债券市场对央行的利率调控目标不敏感,不能形成明确预期。另一方面,货币政策对目标利率的市场引导效果十分敏感,银行间市场债券交易信息是央行制定货币政策的依据。     

Desperately seeking cash: Evidence from bank output measurement

We examine the impact of a “near-zero” interest rate policy on bank output. Specifically, we document the existence of negative banking output on deposits for French banks from 2009. We show a structural break in banks' long run interest rate pass-through that explains this change in their business model during the 2003–2012 period. Since the crisis, banks are desperately seeking cash, and deposits have become a cost center. This is due to the new monetary policy and reveals banks' adaptation to the new banking regulation on liquidity. This new environment raises questions about banks' increasing exposure to interest rate risk and shows the necessity of coordinating monetary and regulatory policies.     

Do central banks respond to exchange rate movements? Some new evidence from structural estimation

This paper investigates the impact of exchange rate movements on the conduct of monetary policy in Australia, Canada, New Zealand, and the United Kingdom. We develop and estimate a structural general equilibrium model, in which monetary policy is represented as a simple rule and exchange rate pass‐through is incomplete due to the presence of local currency pricing and distribution services. We find that the Bank of Canada, the Reserve Bank of New Zealand, and the Bank of England have not adjusted interest rates in response to exchange rate movements since the adoption of inflation targeting, while our model selection results for Australia are less clear.     

Some Fiscal Implications of Monetary Policy

We study the implications of alternative monetary targeting procedures for real interest rates and economic activity. We find that countercyclical monetary policy rules lead to higher real interest rates, higher average tax rates, lower output but lower variability of tax rates and consumption relative to procyclical rules. For a country with a high level of public debt (e.g. Italy), the adoption of a countercyclical procedure such as interest rate pegging may conceivably raise public debt servicing costs by more than half a percentage point of GNP. Our analysis suggests that the current debate on the targeting procedures of the European Central Bank ought to be broadened to include a discussion of the fiscal implications of monetary policy.     

What Monetary Policy after the Crisis?

The objective of this paper is to reflect on some of the implications that recent economic experience has for monetary and financial stability policies. We contend that the financial crisis and the upsurge in inflation 2007–08 have shown that the policy model based on the new consensus in macroeconomics, which largely held sway over the past decade or more, is broken. It is argued that inflation targeting cannot deliver low inflation. We argue that fine-tuning through interest rates should not be attempted, but rather a constant real interest rate target based on the output growth rate should be adopted. The key objective of monetary policy should be shifted to financial stability, the independence of central banks should be brought to an end, and their decision making should be coordinated with other macroeconomic policy initiatives.     

Unveiling the objectives of central banks: Tales of four Latin American countries

We estimate the stabilization objectives of four Latin American countries that have implemented a flexible inflation targeting regime recently: Brazil, Chile, Colombia and Peru. In doing so, we develop a New Keynesian dynamic stochastic general equilibrium model for these economies and estimate their structural parameters through Bayesian methods. To infer the stabilization objectives in each country, we assume that central banks set monetary policy optimally. Our main results highlight that the central banks in these four countries have a high preference for stabilizing inflation, but do not have the systematic objective of stabilizing the exchange rate. This result is robust to assuming either commitment or discretion in the optimal policy. Also, in contrast to the case of commitment, assuming discretion in the optimal monetary policy increases the preference for interest rate smoothing, making it comparable to a preference for inflation stabilization. Finally, except for the case of Peru, the monetary policy under discretion has a better empirical fit in these countries than the one under commitment.     

The recent boom–bust cycle: The relative contribution of capital flows, credit supply and asset bubbles

We use an estimated open economy DSGE model with financial frictions for the US and the rest of the world to evaluate various competing explanations about the recent boom–bust cycle. We find that the savings glut hypothesis is insufficient for explaining all aspects of the boom in the US. Relatively strong TFP growth and expansionary monetary policy are also not able to explain fully the volatility of corporate and in particular residential investment. We identify bubbles in the stock and housing market as crucial. Concerning the downturn in 2008/2009, the fall in house prices and residential investment only plays a minor role. Mortgage defaults have more explanatory power, especially in a specification of the model with a segregated equity market. Finally, the bursting of the stock market bubble was at least as important in this recession as in 2001. Because of various negative shocks hitting the economy at the same time in 2008/2009 and continued positive technology growth, not only the real interest rate declined but inflation fell rapidly and left insufficient room for monetary policy to play a similar stabilising role as in previous recessions.
