Monetary policy and commodity terms of trade shocks in emerging market economies

Commodity terms of trade shocks have continued to drive macroeconomic fluctuations in most emerging market economies. The volatility and persistence of these shocks have posed great challenges for monetary policy. This study employs a New Keynesian Dynamic Stochastic General Equilibrium (DSGE) model to evaluate the optimal monetary policy responses to commodity terms of trade shocks in commodity dependent emerging market economies. The model is calibrated to the South African economy. The study shows that CPI inflation targeting performs relatively better than exchange rate targeting and non-traded inflation targeting both in terms of reducing macroeconomic volatility and reducing the losses of a non-benevolent central bank. However, macroeconomic stabilisation comes at a cost of increased exchange rate volatility. The results suggest that the appropriate response to commodity induced exogenous shocks is to target CPI inflation.     

The Simple Post-Keynesian Monetary Policy Model: An Open Economy Approach

Monetary policy with an inflation targeting rule is analyzed through a simple small-scale Post-Keynesian model that incorporates open economy issues. In contrast with previous Post-Keynesian attempts, the model embodies policy authorities that are committed not only to hitting inflation and/or output targets, but also to the achievement of the external balance. To take account of the external balance objective, we model the real exchange rate as an endogenous and moving target, with the nominal exchange rate being the instrument of that target. The model shows that in response to an adverse external shock the central bank has to consider first the required real exchange rate adjustment that will preserve the external balance, and secondly the level at which the interest rate must be set in order to maintain inflation stabilization. Keeping inflation to target requires higher interest rates and strong reliance on the unemployment channel which, under certain circumstances, also has adverse side effects on income distribution. We show that to deal with an exogenous external shock a policy mix of real exchange rate targeting and income distribution targeting outperforms inflation targeting.     

Exchange Rate Asymmetry and Flexible Exchange Rates under Inflation Targeting Regimes: Evidence from Four East and Southeast Asian Countries

While many have underscored the role of a flexible exchange rate policy under an inflation targeting (IT) regime, very few studies have examined what actually happens to exchange rate policy once the emerging market announces that it will adopt inflation targeting. The central contention of this paper is that while the adoption of an inflation targeting (IT) policy may lead to more flexible exchange rate movements, for various reasons it is possible that the degree of flexibility will be significantly higher on one side of the market. In this study, we demonstrate that four Asian economies—namely, Indonesia, Korea, the Philippines and Thailand—whom were among the first group of emerging markets to embrace the inflation targeting framework of monetary policy, tend to adopt a form of asymmetrical exchange rate behavior, wherein appreciation pressures are restrained more substantially than depreciation pressures.     

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.     

Foreign output shocks,monetary rules and macroeconomic volatilities in small open economies

The 2008 financial crisis is marked by the drop in output of major industrial countries which affected small open economies in various degrees. We examine the role of three different types of monetary policy rules in mitigating or exacerbating the effects of a negative foreign output shock on key macroeconomic variables of a small open economy by numerically solving a dynamic stochastic general equilibrium (DSGE) model. We find that compared to the Taylor rule, small open economies that follow either fixed exchange rate regime or strict inflation targeting tend to stabilize real exchange rate and inflation at the expense of substantial instability in the real economy.     

What do Latin American inflation targeters care about? A comparative Bayesian estimation of central bank preferences

This paper employs Bayesian estimation to uncover the central bank preferences of the five Latin American inflation targeting countries with floating exchange rates: Brazil, Chile, Colombia, Mexico, and Peru. The target weights of each country’s central bank loss function are estimated using a medium-scale small open economy New Keynesian model with imperfect exchange-rate pass-through under either complete or incomplete international asset markets. Bayesian model comparison selects: (i) unambiguously the complete markets model version; (ii) the model specification with explicit concern for real exchange rate stabilization, with the exception of Peru. Our results suggest that the central banks of Mexico and Peru are closest to following a strict inflation targeting regime, whereas Brazil, Chile, and Colombia also assign a sizeable weight to output gap and real exchange rate stabilization. Finally, the estimated preference weights for each central bank are shown to credibly reflect their legal mandates.     

Inflation targeting in emerging market and transition economies: Lessons after a decade

Starting in the early 1990s, several emerging market and transition economies adopted inflation targeting (IT). In this paper we discuss a number of issues that arise in this context: (a) the definition of IT, (b) the role of preconditions for IT, (c) the use of intermediate exchange rate targets, and (d) the specification of inflation targets. Our overall conclusion is that, suitably modified, IT is a useful policy strategy for EMEs.     

通胀目标制与汇率目标制不能共存吗

基于汇率传递的风险溢价渠道，本文将我国利率调控通胀、外汇储备对冲干预汇率纳入新凯恩斯政策模型，构建双目标双工具政策分析框架，比较泰勒规则与双目标双工具规则下通胀目标与汇率目标共存的经济机制与效应。本文模拟显示：（1）双目标双工具政策框架下通胀目标与汇率目标能够共存，此时通过影响汇率风险溢价来盯住汇率不影响通胀；而单工具政策下两目标无法共存，此时降低国内资产的收益率盯住汇率会刺激居民的消费行为引起通胀。（2）国际资本冲击下，双目标双工具政策在固定汇率的同时能保证经济稳定；而当贸易条件恶化时，选择完全浮动汇率制度最优。央行政策损失分析进一步验证了以上结论。（3）随着金融市场化改革深入，外汇储备稳定汇率的有效性将下降，冲销成本会大幅提升。资本账户开放下，双目标双工具政策仍是央行抵御外部资本冲击的首选政策；但是汇率市场化后，通胀目标制与双目标双工具政策效果基本无差异。本文结论的启示是：面对国际资本，需必要的汇率管制；但是面对贸易冲击，可适度提升汇率弹性来减少冲击对产出和通胀的影响。     

How should emerging economies float their currencies?

Floating exchange rates seem to be gaining ground in Latin America, East Asia and the transition economies. The recent crises left many economies with no alternative but to float. Others have moved toward floating, searching for greater flexibility and insulation from external shocks. The question for most emerging market economies, then, is no longer to float or not to float, but how to float. Four issues arise in this regard. The first is how to float and have low inflation. The second is whether floating provides as much insulation as conventional theory predicts, especially in the presence of dollarized liabilities. Which leads to the third point: the relationship between the stability of the exchange rate and that of the financial system. The fourth is how to conduct monetary policy under a float, and the role of inflation targeting. We consider each of these points in turn, and conclude that a workable model of how to float seems to be emerging from the so‐far successful experience of countries like Chile and Brazil. It involves the adoption of an inflation target as the main anchor for monetary policy, coupled with a monetary policy reaction function that — aside from reacting to the output gap and other determinants of the inflation rate — reacts also partially to movements in the nominal exchange rate.

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.     

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.     

Foreign output shock in small open economies: A welfare evaluation of monetary policy regimes

We examine the impact of negative foreign output shocks, which entail negative demand side effects by lowering exports and positive supply side effects by lowering oil prices, on the welfare of non-oil producing, small open economies under five exchange rate and monetary policy regimes. We use a dynamic stochastic general equilibrium model with parameter values calibrated for Hong Kong, Israel, Singapore, South Korea and Taiwan. We find that welfare levels among the five policy regimes depend on the economy's share of oil imports in world oil consumption. Hong Kong, Singapore and Israel, which have smaller shares, maximize welfare under the Taylor rule, which targets both CPI inflation and real output. South Korea, with higher shares, and Taiwan, with more rigid prices, maximize welfare under real output targeting. CPI inflation targeting, nominal output growth targeting and fixed exchange rate regimes generate lower welfare. However, optimal monetary policy, which generates the highest welfare, gives greater weight on real output than CPI inflation.     

Monetary policy rules for financially vulnerable economies

One distinguishable characteristic of emerging market economies is that they are not financially robust. These economies are incapable of smoothing out large external shocks, as sudden capital outflows imply abrupt swings in the real exchange rate. Using a small open-economy model, this paper examines alternative monetary policy rules for economies with different degrees of liability dollarization. The paper answers the question of how efficient it is to use inflation targeting (IT) under high liability dollarization. Our findings suggest that it might be optimal to follow a nonlinear policy rule that defends the real exchange rate in a financially vulnerable economy.     

Optimal monetary policy regime for oil producing developing economies: Implications for post-war Iraq

This paper theoretically investigates optimal monetary policy regime for oil producing developing countries. We analyze credibility and reputation of the Central Bank and macroeconomic dynamics under alternative monetary policy regimes. We construct a detailed and realistic model that can be used to analyze macroecomic structure and expectation dynamics of an oil producing open economy. We take into account the asymmetric information between the public and the central bank and theoretically investigate how this asymmetric information impacts the real economy and the credibility of the central bank. The simulation results indicate that central bank achieves higher credibility and lower inflation under dollarization and higher output levels under currency board regime. The model constructed in this paper has many policy implications for oil producing open economies. Using the implications of the model, we make monetary policy regime recommendations for post-war Iraq.     

On the determinants of long-run inflation uncertainty: Evidence from a panel of 17 developed economies

Based on a cross section of 17 advanced economies and data for the period 1975 to 2015, we examine how the interaction between monetary policy and macroeconomic conditions affects inflation uncertainty in the long-term. We construct a proxy for the unobservable inflation uncertainty based on the slowly evolving long-term variance component of inflation from a Spline-GARCH model (Engle and Rangel, 2008). We show that long-run inflation uncertainty is high if an inflation-tolerant central bank governor is in power during a period of high inflation, if the policy rate is below the one that is prescribed by the Taylor rule and during times of heightened stock and exchange rate volatility.     

INFLATION TARGETERS IN PRACTICE: A LUCKY LOT?

Some observers have attributed the success of inflation targeters in reducing inflation to the global disinflation of the 1990s. As a result, inflation targeting countries have been considered to be a lucky lot. One key policyimplication of that is that if the international environment becomes again hostile to low inflation in the future, inflation targeting will prove to have been a mere fad. This article views inflation targeting not just as a rule but as a framework for the conduct of monetary policy, and it argues that currently available analyses of the experience of inflation targeting countries have serious weaknesses. One weakness is that those studies have not taken into account that regime changes may alter the quantitative and qualitative interaction among small, open economies and the rest of the world. Another weakness is that those studies have not recognized that the extraction of common trends and cycles is contingent on the nature of the monetary policy regime. It is likely that inflation targeting frameworks may imply a new beneficial trend in monetary policy making. This suggests that if the international environment becomes again hostile to low inflation in the future, an inflation targeting framework may become a viable alternative to a central bank that remains committed to price stability.     

Exchange rates,central bank news and the zero lower bound*

The zero lower bound (ZLB) may restrict the responsiveness of exchange rates to news. A proxy for central bank communication is added as a determinant in a model of exchange rate movements. Two reserve currencies, the British pound and euro, and two currencies of small open economies, the Canadian dollar and Swedish krona, are examined. Reserve currencies are more vulnerable to the ZLB constraint, while the currencies of small open economies become more responsive to foreign central bank announcements. Certain unconventional monetary policy announcements were found to significantly impact exchange rates at the ZLB.     

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.     

The relationship between exchange rates and interest rates in a small open emerging economy: The case of Romania

This paper revisits the relationship between interest rates and exchange rates in a small open emerging economy using wavelet-based methodologies. Based on data for Romania, our results confirm the theoretical predictions on the interest rate - exchange rate relationship during turmoil or policy changes. In the short term, the relationship is negative, confirming the sticky-price models, and over the long term, the relationship is positive, confirming the Purchasing Power Parity theory. At the beginning of the turmoil, the exchange rate movements generally take the lead over the interest rates for the first month, but the monetary authorities take the lead afterwards. Our results reveal that in a small open emerging economy with a direct inflation targeting monetary policy regime, the relationship between exchange rates and interest rate is fundamentally different from that in an advanced economy. Also, our results stress the necessity that the central bank must pay simultaneous attention to both variables in order to achieve their monetary policy targets.     

The effect of a Chinese slowdown on inflation in the euro area and the United States

We investigate the effect of a Chinese slowdown on inflation in the euro area and the United States using the NiGEM multi-country model. We construct different scenarios including a fall in Chinese aggregate demand, a commodity price slump, financial market corrections and a devaluation of the renmimbi. While the commodity slump has the strongest impact on inflation, the demand and exchange rate shocks also play a role; on the contrary, financial turbulences have minor effects. Finally, we study the extent to which monetary policy in advanced economies can succeed in reflating the economy following such a Chinese slowdown. The room for central bank interventions is large.
