A comparison of optimal policy rules prior to and during inflation targeting: empirical evidence from Bank of Canada

We examine policy rules that are consistent with inflation targeting (IT) framework in a small macroeconomic model of the Canadian economy. We set up an optimal linear regulator problem and derive policy rules to compare the dynamics of pre-IT and IT eras. We find that while the optimal monetary policy rule in the pre-IT period is best described with a loss function that attaches equal weight to price stability, financial stability and output stability; the IT era is dominated by the price stability objective followed by the financial stability and output stability, consecutively. Moreover, we do not find an explicit role for exchange rate stability in the objective function of the Bank of Canada for both monetary policy eras. We, then, compare the properties of the derived optimal rules with those of an ad hoc Taylor rule for the IT period. In response to inflationary shocks, Taylor rule brings down inflation rates more quickly compared to the derived policy rules, but at the cost of a higher sacrifice ratio and more volatile interest rates.     

An assessment of inflation targeting in a quantitative monetary business cycle framework: evidence from four early adopters

This article examines the effectiveness of inflation targeting (IT) to stabilize the real economy in advanced countries where IT was adopted in the early 1990s. To quantitatively assess IT, this article employs the monetary business cycle accounting methodology recently developed by ?ustek (2011), which is an extended version of Chari, Kehoe, and McGrattan (2007), to monetary models. Our main finding is that the monetary policy wedge that captures economic fluctuations caused by monetary policy has significantly declined since the implementation of IT in the early 1990s. The results suggest that advanced economies, such as Australia, Canada, Sweden and the United Kingdom, that adopted IT in the early 1990s have been successful in stabilizing business cycle fluctuations.     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

房地产价格、泰勒规则与宏观经济调控——基于2000-2010年我国宏观经济数据的检验

央行是否应该针对房地产价格制定货币政策进行调控,一直是学者们关注的焦点,但研究结果仍存在分歧。基于2000-2010年我国季度经济数据,对比检验了融入房地产价格的泰勒规则与标准泰勒规则对我国制定货币政策调控宏观经济的适用性。实证结果表明,依据标准泰勒规则所制定的利率政策,可以降低央行损失函数值,提高利率政策有效性。这一结果意味着,在房地产价格波动不影响物价稳定和经济增长的情况下,央行不应针对房地产价格进行调控。也就是说,央行需考虑房地产价格波动与通货膨胀和产出之间的相关关系,判断其对政策目标的潜在影响,制定利率政策对宏观经济进行调控。     

Is inflation targeting a good remedy to control inflation?

Since the 1990s inflation targeting (IT) has been adopted by several central banks as a strategy for monetary policy. It is expected that the adoption of this monetary regime can reduce inflation and inflation volatility. This article is concerned with these issues and makes use of the Propensity Score Matching methodology on a sample of 180 countries for the period from 1990 to 2007. For analysis, the sample is split into two sets of countries (advanced and developing). The findings suggest that the adoption of IT is an ideal monetary regime for developing economies and, in addition to reducing inflation volatility, can drive inflation down to internationally acceptable levels. Regarding advanced economies, the adoption of IT does not appear to represent an advantageous strategy. In brief, the empirical results indicate that the adoption of IT is useful for countries that must enhance their credibility for the management of monetary policy.     

A small-scale DSGE-VAR model for the Romanian economy

This paper describes the theoretical structure and the estimation results for a DSGE-VAR model for the Romanian economy, an inflation targeting country since 2005. Having as benchmark the New-Keynesian model of Rabanal and Rubio-Ramirez (2005), the main additional feature introduced refers to the extension to a small open economy setting in order to account for this specific aspect of the Romanian economy.Within the inflation targeting monetary policy regime, forecasts of central macro variables, inflation in particular, play an important part. Because inflation reacts to monetary measures with a considerable lag, the central bank's policy has to be forward-looking. Based on univariate measures of forecast performance, it is shown that the VAR with DSGE model prior produces forecasts that improve on those obtained using an unrestricted VAR model and the popular Minnesota prior in case of inflation, real exchange rate and nominal interest rate. Moreover, the DSGE-VAR model is informative about the structure of the economy and can help the “story-telling” in the central banks.     

中国货币政策对资产价格波动反应的模拟分析

利用包含汇率波动和通胀预期的IS-Philips模型推导考虑资产价格的货币政策反应函数。在此基础上,分别以股价和房价作为资产价格的代理变量,模拟分析了资产价格波动对中国经济的影响。研究结果表明:考虑资产价格的货币政策在平抑产出和物价波动方面具有显著作用,但会增大利率波动幅度;考虑房价波动的货币政策比考虑股价波动的货币政策在平抑产出和物价波动方面具有更好的效果;与考虑股价波动的货币政策相比,考虑房价波动的货币政策对利率的冲击更小。     

Re‐vitalizing money demand in the Euro area. Still valid at the zero‐lower bound

The analysis of monetary developments has always been a cornerstone of the ECB's monetary analysis and, thus, of its overall monetary policy strategy. In this respect, money demand models provide a framework for explaining monetary developments and assessing price stability over the medium term. It is a well‐documented fact in the literature that, when interest rates are at the zero‐lower bound, the analysis of money stocks become even more important for monetary policy. Therefore, this paper re‐investigates the stability properties of M3 demand in the euro area in the light of the recent economic crisis. A cointegration analysis is performed over the sample period 1983 Q1 and 2015 Q1 and leads to a well‐identified model comprising real money balances, income, the long‐term interest rate and the own rate of M3 holdings. The specification appears to be robust against the Lucas critique of a policy dependent parameter regime, in the sense that no signs of breaks can be found when interest rates reach the zero‐lower bound. Furthermore, deviations of M3 from its equilibrium level do not point to substantial inflation pressure at the end of the sample. Excess liquidity models turn out to outperform the autoregressive benchmark, as they deliver more accurate CPI inflation forecasts, especially at the longer horizons. The inclusion of unconventional monetary policy measures does not contradict these findings.     

Profit Differences and Corporate Power: Some Empirical Surprises

Inflation targeting is currently the policy of choice for central banks. This policy invariably targets consumer price inflation, which is only one of many available price level indices (such as prices of new investments and house prices). As there is no stable relationship between these price levels, and as differences in developments between the different price levels might induce destabilizing behavior, there is no reason why “low and stable” consumer price inflation should guarantee monetary and financial stability. Following John Maynard Keynes, a “low and stable” increase of average nominal wages might do a better job. As price levels are designed to estimate the purchasing power of spending power and as income, and spending power are used to not just consume or invest but also to pay down many kinds of (gross) debt, it is advisable to use a joint definition of monetary and financial stability, which combines stable purchasing power of monetary income with a stable ability of households and companies to pay off debts.     

On the Future of Inflation Targeting in East Asia

This article analyzes the problems associated with inflation targeting (IT) regimes in a number of East Asian countries. It scrutinizes the policy conflicts that can arise when a central bank that has adopted a formal inflation target to guide the conduct of monetary policy simultaneously manages the exchange rate and pursues financial stability objectives. To this end, it empirically investigates the importance of exchange rate and terms of trade movements as determinants of inflation rates across East Asian economies and discusses the role of central banks in guarding financial stability and the ways this may conflict with an IT regime. The article argues that IT never really has been a suitable monetary framework for East Asian countries and that it should hence be supplanted by transparent monetary frameworks that explicitly recognize the multiple goals that are being pursued by East Asian central banks.     

Professor Fisher and the quantity theory – a significant encounter

Abstract

Irving Fisher's encounter with the Quantity Theory of Money began in the 1890s, during the debate about bimetallism, and reached its high point in 1911 with the publication of The Purchasing Power of Money. His most important refinement of the theory, derived from his recognition of bank deposits as means of exchange, was to treat their out of equilibrium recursive interaction with inflation as integral to it. This treatment underlay both his 1920s work on the business cycle as a “dance of the dollar” and his advocacy of subjecting monetary policy to a legislated price stability rule, initially to be based on his “compensated dollar” scheme. Fisher's failure to recognise the onset of the Great Depression even as it was happening was directly related to his faith in the quantity theory's seeming implication that price level stability in and of itself guaranteed the continuation of prosperity, while his subsequent work on the debt deflation theory of great depressions initially failed to repair the damage that this failure did to his reputation, and to that of the quantity theory. In the 1930s Fisher nevertheless remained an active supporter of various schemes to reflate and then stabilise the price level. His subsequent influence on the quantity theory based Monetarist counter-revolution that began in the 1950s lay, directly, in its deployment of his analysis of expected inflation on nominal interest rates, and, indirectly, in its espousal of the case for subjecting monetary policy to a legislated rule.     

A Note on Inflation Targeting

The authors present a pedagogical graphical exposition to illustrate the stabilizing effect of price target zones. Based on a textbook AD-AS apparatus, they find that authorities' commitment to defend a price target zone will affect the public's inflation expectations and, in turn, reduce actual inflation. They also find that, when the economy experiences supply shocks, the announcement that the monetary authorities intend to defend a price target zone will reduce the variability of domestic prices but raise the variability of domestic output relative to a free-price regime. However, when the economy experiences demand shocks, a price target zone tends to lower the variability of both domestic prices and out-put relative to a free-price regime.     

Inflation volatility,economic growth and monetary policy in Bangladesh

This article provides an overview of the trends and movements of CPI-inflation in Bangladesh since the early 1950s and examines the key issues in rule-based monetary policy for price stability, implying low and stable inflation, in this country. Under a fixed exchange rate system, inflation in Bangladesh was moderately high and volatile during the 1950s and 1960s. Since the country’s independence from Pakistan in 1971, inflation in Bangladesh has remained moderately high on average and highly volatile and persistent under a fixed-pegged exchange rate system or under a managed floating system since 2003. Using data from the early 1970s or earlier depending on data availability, the article undertakes both Granger-causality and the structural vector autoregression (SVAR) analysis with two models. The first model is comprised of such variables as inflation, the real interest rate, the real exchange rate and output growth, and the second model is comprised of the volatilities of money growth, real output growth and inflation. Then, based on the empirical findings, the article concludes that a rule-based monetary policy, namely monetary targeting or inflation targeting, remains appropriate for Bangladesh provided that it adopts a more flexible, if not freely floating, exchange rate system. The article suggests that the use of monetary policy to achieve multiple objectives under a fixed-pegged exchange rate system creates a time-inconsistency problem, reduces monetary policy credibility and makes it (monetary policy) ineffective in lowering inflation and its volatility. Low credibility of monetary policy in particular raises inflation persistence. Within the present monetary-policy framework in Bangladesh, the article illustrates how the fixed-pegged exchange rate system has generated money growth volatility in the presence of large-scale inflows of overseas workers’ remittances and readymade garments export earnings. This does not seem to be a concern of the central bank of Bangladesh (Bangladesh Bank); rather, it (Bangladesh Bank) pursues monetary-base targeting to keep inflation low and stable after considering economic growth. The consequent diminishing credibility of monetary policy has kept inflation volatile and persistent, which has adversely affected economic growth.

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.     

TAYLOR RULE REACTION COEFFICIENTS AND REAL EXCHANGE RATE PERSISTENCE

Recent literature has established a link between the persistence of real exchange rates and the degree of inertia in Taylor rule monetary policy reactions functions. This paper provides a different view on this link by investigating how the size of Taylor rule reaction coefficients impacts the adjustment dynamics of the real exchange rate. Within a stylized sticky‐price open‐economy macro model, it is demonstrated that a stronger interest rate reaction to inflation in the Taylor rule raises the convergence speed of the real exchange rate. Conversely, raising the coefficient on the output gap or attending to the exchange rate in an open‐economy version of the Taylor rule slows down real exchange rate adjustment. In all cases, more rapid convergence comes at the cost of stronger initial real exchange rate misalignments in the wake of monetary policy shocks.     

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.     

通货膨胀、汇率波动与货币政策——基于符号约束的贝叶斯VAR模型实证研究

通过构建通货膨胀形成的理论模型,本文运用符号约束的贝叶斯VAR方法探讨通货膨胀和汇率波动对产出增长的影响。结果发现：实际利率对通货膨胀和人民币升值冲击均有较大的响应,且受通货膨胀的影响更大,即稳定价格的货币政策比稳定汇率的政策更加有效;通货膨胀冲击下,实际利率在长期有所上升,但并未达到控制通货膨胀的效果,实际利率偏低阻碍了货币政策效果的发挥;人民币升值对产出增长具有较大的负面影响,对通货膨胀具有负向）中击,但由于油价上涨的原因,人民币升值并没有降低通货膨胀水平。     

Monetary policy strategies in the New Normal: A model-based analysis for the euro area

A calibrated New Keynesian model of the euro area is used to evaluate the stabilization properties of alternative monetary policy strategies when the natural rate of interest is low (“new normal”) and the probability of reaching the effective lower bound (ELB) is non-negligible. Price level targeting is the most effective strategy in terms of stabilizing inflation and output and reducing the duration and frequency of ELB episodes. Temporary price level targeting is also effective in mitigating the ELB constraint, although its stabilization properties are inferior to those of price level targeting. Backward-looking average inflation targeting performs well and is preferable to inflation targeting. The effectiveness of these alternative strategies hinges upon the commitment of a central bank to keeping the policy rate “lower for longer” and is influenced by agents’ expectation formation mechanism.     

Time‐Varying Dynamics of the Norwegian Economy

We use time‐varying parameter vector autoregressive models to investigate possible changes in the time‐series properties of key Norwegian macroeconomic variables since the 1980s. Notably, we find that inflation persistence falls during the inflation targeting period, while the volatility of inflation and nominal exchange rates increases. The observed time‐variation in the correlations between the interest rates and the macro variables largely reflects the prevailing monetary policy regimes. An increase in the correlations between oil prices and other macro variables over time is also documented. Using a counterfactual analysis, we discuss the observed time‐varying dynamics of the Norwegian economy in the light of monetary policy and oil price shocks.     

Shadow rates as a measure of the monetary policy stance: Some international evidence

This paper examines the usefulness of shadow rates to measure the monetary policy stance by comparing them to the official policy rates and those implied by three types of Taylor rules in both inflation-targeting countries (the UK, Canada, Australia and New Zealand) and others that have only targeted inflation at times (the United States, Japan, the Euro Area and Switzerland) over the period from the early 1990s to December 2021. Shadow rates estimated from a dynamic factor model are shown to suggest a much looser policy stance than either the official policy rates or those implied by the Taylor rules, and generally to provide a more accurate picture of the monetary policy stance during both ZLB and non-ZLB periods, since they reflect the full range of unconventional policy measures used by central banks. Furthermore, generalised impulse response analysis based on three alternative vector autoregression (VAR) models indicates that monetary shocks based on the shadow rates are more informative than those related to the official policy rates or to two- and three-factor shadow rates, especially during the Global Financial Crisis and the recent COVID-19 pandemic, when unconventional measures have been adopted. Finally, unconventional policy shocks seem to have less persistent effects on the economy in countries, which have adopted an inflation-targeting regime.
