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.     

Macroeconomic dynamics in Macedonia and Slovakia: Structural estimation and comparison

This paper estimates a structural macroeconomic model using data for Macedonia and Slovakia to characterize possible challenges Macedonia can face concerning macroeconomic stabilization during its transition process. A comparison of the estimated model parameters suggests that, in Slovakia, the output gap is less sensitive to real interest rate movements and prices experience greater inertia. The estimated monetary policy reaction functions show Macedonia and Slovakia as inflation targeters, with Macedonia as the more conservative one, despite its officially applied exchange rate targeting regime. The differences in the estimated parameters imply differing transmission mechanisms for Macedonia and Slovakia. Consequently, the variance of domestic variables in Slovakia is most influenced by monetary policy shocks, while there is no single dominating shock explaining the volatility of Macedonia's macroeconomic variables. The exchange rate shock, the monetary policy shock and the demand shock are jointly important in determining the volatility of Macedonia's variables. The model simulations indicate that Macedonia experiences lower output gap and inflation volatility than Slovakia. This comes, nevertheless, at the cost of higher interest rate and real exchange rate volatility in Macedonia, which could be an indication of more volatile financial markets with possible negative implications for financial stability.     

Inflation Targeting and Inflation Uncertainty

This article empirically investigates the impact of inflation targeting on inflation uncertainty. We implement PARCH and GARCH methodologies to model conditional variance of inflation. We also investigate the relationship between level and volatility of inflation to analyze the validity of the Friedman hypothesis for IT countries. We find that most of the inflation targeting countries have significantly lower inflation variances after inflation targeting. In most of the IT countries, the relationship is consistent with the Friedman hypothesis.     

Exchange rate pass-through in the Asian countries: does inflation volatility matter?

This paper presents a nonlinear relationship between exchange rate pass-through (ERPT) and inflation volatility. Through the lens of a threshold framework, we uncover a clear evidence of near to one ERPT to consumer prices once inflation volatility crosses a threshold level of 4.17. Clearly, there are significant differences in the degree of ERPT between the high and low inflation volatility in the inflation targeting (IT) and non-IT Asian countries.     

Exchange Rate Passthrough Effects and Inflation Targeting in Emerging Economies: What is the Relationship?

Several studies have shown that over the past 10 years the passthrough effect from currency depreciation into domestic inflation has been decreasing in emerging economies that adopted inflation targeting (IT) during the mid and late 1990s. Therefore the nominal exchange rate effect on domestic inflation is becoming less of an issue for these countries. The literature has offered different explanations for these declines but so far they have not been directly related to the adoption of IT. This paper shows that lower passthrough effects can also be the result of the implementation of an IT regime and argues, contrary to previous studies, that the effects of the nominal exchange rate on inflation are still a relevant issue for emerging IT countries. The reason for this is that the empirical evidence offered for the lower passthrough misses the nature of the relationship between inflation and the nominal exchange rate under IT.     

Is inflation targeting credible in Asia? A panel GARCH approach

We examine the relationship between inflation targeting and the behavior of the level and volatility of inflation for eight Asian countries over the period 1987–2013. In contrast to existing studies that rely upon time series methods, we employ a novel panel GARCH model that accounts for heterogeneity and interdependence across countries. Our main contribution is to shed new light on the inflation targeting credibility hypothesis based on lower inflation and inflation volatility as well as on the correlation between unanticipated inflation shocks within a panel GARCH framework. We find strong evidence of a reduction in the level of inflation that operates from the impact of actual inflation targets in the Philippines, South Korea and Thailand. We also find that the adoption of inflation targeting helped lower inflation volatility in the Philippines and South Korea. Overall, the results suggest that Asian inflation targeting regimes are more credible in terms of reducing the level of inflation than lowering inflation volatility. There is also evidence that the covariance of inflation shocks among inflation targeting and non-targeting countries tends to increase.     

Price‐level versus inflation targeting with financial market imperfections

Abstract Price‐level targeting (PT) is compared with inflation targeting (IT) in a DSGE model augmented with imperfections in both debt and equity markets. The PT regime outperforms the IT regime, and the gain depends on the degree of financial market frictions. This is because inflation is better anchored under PT, owing to the expectation channel, and therefore the monetary authority has more leverage to deal with the financial market distortions. We also find that the gain is higher if the optimal rule reacts to asset prices instead of the output gap, and the rule requires a positive response to asset prices.     

A general equilibrium open economy model for emerging markets: Monetary policy with a dualistic labor market

An optimizing model of a small open emerging market economy (SOEME) with dualistic labor markets and two types of consumers, delivers a tractable model for monetary policy. Differences between the SOEME and the SOE are derived. Parameters depend on features of the labor market and on consumption inequality, and affect the natural interest rate, terms of trade and potential output. The supply curve turns out to be flatter and more volatile, with a larger number of shift factors, including policy-determined terms of trade. A simple basic version of the model is simulated in order to compare different policy targets in response to a cost shock. Flexible domestic inflation targeting gives the lowest volatility although there are trade-offs. Exchange rate volatility is relatively lower but still makes a major contribution to controlling inflation. Flexible CPI inflation targeting performs better when combined with some kind of managed floating. Inflation targeting has to be flexible. With more backward-looking behavior the policy response to a shock is reduced.     

Performance of inflation targeting in retrospect

Both inflation and inflation expectations declined considerably in the inflation targeting countries during the past two decades. The questions of whether this decline has actually been an outcome of inflation targeting solely and whether inflation targeting has been successful in stabilizing other macroeconomic variables though remain. This study considers these questions on the basis of 16 inflation targeting countries and 21 non-targeting ones using a difference-in-difference approach. With regard to the baseline period of 1996–1999 during which neither of the groups was implementing inflation targeting, a difference-in-difference approach was employed to assess the effects of inflation targeting on inflation, output growth, real exchange rates, inflation volatility and real exchange rate volatility during moving 4-year periods between 2007 and 2015. Our estimates suggest that inflation targeting was superior in terms of harnessing inflation as well as inflation volatility. In terms of economic growth, however, inflation targeting seems to be neutral and in terms of real exchange rates it seems not to be stabilizing, if not de-stabilizing. A hybrid version of inflation targeting, namely the conventional inflation targeting augmented by an improved capacity to deliver macro-prudence as in the post-Lehman economic climate, can therefore be viewed as the best available policy alternative for the upcoming decades.     

Constrained discretion in Sweden

We study whether the institutional adoption of inflation targeting (IT) has constituted both a policy and a macroeconomic switch in Sweden using the nonlinear MSVAR technique. We assess the relative weight put on inflation in the monetary reaction function and the capacity of IT to reduce macroeconomic uncertainty. We show that IT has constituted a policy switch to a lower focus on inflation, in contrast with the usual argument that has been put forth by IT opponents. Moreover, IT adoption is shown to have reduced uncertainty, through lower inflation and output variabilities simultaneously. Last, counterfactuals suggest IT provides higher monetary policy leeway.     

Inflation Volatility and Forecast Accuracy

We examine the statistical properties of inflation in a sample of inflation‐targeting (IT) and non‐IT countries. It is hard to distinguish in which monetary regime inflation is less volatile. Inflation became easier to forecast in both groups of countries after the introduction of IT. The improvement was greater for IT countries, but forecast errors remain smaller for non‐IT countries. Our analysis is based on a stochastic volatility model proposed by Stock and Watson and its novel modification. Forecasts from the modified model are generally superior to both simple benchmarks and the original Stock and Watson model.     

Inflation targeting in Latin America: Empirical analysis using GARCH models

This paper studies inflation dynamics in eight Latin American countries, some of which have adopted formal inflation targets (IT) as their monetary policy frameworks. We analyze the possible benefits associated with IT, not only in terms of inflation level and volatility, but also regarding other nonlinear characteristics of these series, such as volatility persistence or the fulfillment of the Friedman hypothesis. To describe inflation dynamics we use an unobserved components model, where each component can follow a GARCH type process. Once we estimate the model, the main findings of the empirical exercise confirm the favorable performance of IT.     

Monetary policy regime change and regional inflation dynamics: looking through the lens of sector‐level data for Korea

This paper explores the impact of the adoption of inflation targeting (IT) on the dynamics of city‐level inflation in Korea using both aggregate and sector‐level data. When looking at aggregate regional inflation, we find that the mean, volatility and persistence fell in all cities in the wake of the monetary policy regime change, consistent with other evidence in the literature. Delving more deeply into the disaggregate data reveals additional insights however. For most of the changes we observe in the dynamics of regional inflation, we find that the aggregate effects are being driven primarily by sectors that fall into the ‘Services’ category. We posit that the impact of better anchored inflationary expectations is primarily on the less‐traded services sectors of the economy, where the domestic monetary policy framework has a relatively larger influence. When it comes to the increased co‐movement observed across regions under an IT regime, however, it is the ‘Commodities’ sectors rather than ‘Services’ that are responsible, probably because services inflation becomes relatively more influenced by local factors once it has stabilized within the target range. Therefore, adoption of IT may not necessarily increase all measures of regional synchronization even when the goal of better‐anchored inflationary expectations is achieved.     

STATIC AND DYNAMIC EFFECTS OF CENTRAL BANK TRANSPARENCY

Using a New Keynesian framework, this paper shows that, under optimal discretion and optimal pre‐commitment in a timeless perspective, imperfect transparency about the relative weight assigned by the central bank to output‐gap stabilization generally reduces the average reaction of inflation to inflation shocks and the volatility of inflation, but increases those of the output gap in static and dynamic terms, and more so when inflation shocks are highly persistent. When inflation shocks are moderately persistent, opacity could improve social welfare if the weight assigned to output‐gap stabilization is low and this is more likely under pre‐commitment than under discretion.     

Eurosystem monetary targeting: Lessons from U.S. data

Using a small empirical model of inflation, output, and money estimated on U.S. data, we compare the relative performance of monetary targeting and inflation targeting. The results show monetary targeting to be quite inefficient, yielding both higher inflation and output variability. This is true even with a nonstochastic money demand formulation. Our results are also robust to using a P∗ model of inflation. Therefore, in these popular frameworks, there is no support for the prominent role given to money growth in the Eurosystem's monetary policy strategy.     

Time Series Analysis of Inflation Targeting in Selected Countries

Abstract

We analyze a set of countries which adopted inflation targeting (IT) as a policy tool. We model the pre‐IT period with ARMA and GARCH methods, and conduct the one‐step ahead forecasting for the remainder of the times series data. The actual and forecasted inflation levels are compared for each country. We find that even though the actual inflation levels are lower than the forecasted ones, there is no statistical evidence to suggest that the adoption of IT causes a structural break in the inflation levels of the countries which adopt IT.     

ACCOUNTABILITY AND TRANSPARENCY ABOUT CENTRAL BANK PREFERENCES FOR MODEL ROBUSTNESS

Using a New Keynesian model subject to misspecifications, we examine the accountability issue in a framework of delegation where government and private agents are uncertain about the central bank's preference for model robustness. We show that, in the benchmark case of full transparency, the optimal inflation targeting weight (or penalty) is decreasing with the preference for robustness. Departing from the benchmark equilibrium, the central bank has then incentive to be less transparent in order to reduce the optimal inflation targeting weight and thus to become more independent vis‐à‐vis the government. We also find that greater opacity will increase the sensibility of inflation and model misspecification to the inflation shock but will decrease that of output‐gap. Since macroeconomic volatility could be increased or decreased under more opacity, there could exist in some cases a trade‐off between the level and the variability of inflation (and output gap). Persistent inflation shocks could be associated with a higher inflation targeting weight as well as a higher sensibility of inflation and output gap to the inflation shock but a lower sensibility of model misspecification.     

CROSS-COUNTRY EVIDENCE ON OUTPUT GROWTH VOLATILITY: NONSTATIONARY VARIANCE AND GARCH MODELS

This paper revisits the issue of conditional volatility in real gross domestic product (GDP) growth rates for Canada, Germany, Italy, Japan, the United Kingdom, and the United States. Previous studies find high persistence in the volatility. This paper shows that this finding largely reflects a nonstationary variance. Output growth in the six countries became noticeably less volatile over the past few decades. In this paper, we employ the modified iterated cumulative sum of squares (ICSS) algorithm to detect structural change in the variance of output growth. One structural break exists in each of the six countries after identifying outliers and mean shifts in the growth rates. We then use generalized autoregressive conditional heteroskedasticity (GARCH) specifications, modeling output growth and its volatility with and without the break in volatility. The evidence shows that the time-varying variance falls sharply in Canada and Japan, and disappears entirely in Germany, Italy, the United Kingdom and the United States, once we incorporate the break in the variance equation of output for the six countries. That is, the integrated GARCH (IGARCH) effect proves spurious and the GARCH model demonstrates misspecification, if researchers neglect a nonstationary variance. Moreover, we also consider the possible effects of our more correct measure of output volatility on output growth as well as the reverse effect of output growth on its volatility. The conditional standard deviation possesses no statistical significance in all countries, except a significant negative effect in Japan. The lagged growth rate of output produces significant negative and positive effects on the conditional variances in Germany and Japan, respectively. No significant effects exist in Canada, Italy, the United Kingdom, and the United States.     

Hybrid Inflation-Price-Level Targeting in an Economy With Output Persistence

This paper investigates hybrid inflation‐price‐level targeting (HT), employing a Phillips curve with output persistence. By HT we mean that a central bank targets a weighted average of the optimal inflation rate and its corresponding price level. The analysis shows that if output is persistent to some extent, it is desirable to adopt HT because, relative to the case of alternative regimes such as inflation targeting (IT) and price‐level targeting (PT), it will reduce the variability of inflation and thereby social loss. In addition, it is shown that the optimal hybrid‐type target is uniquely determined according to the degree of persistence in output.     

Spillover Effects of Real and Nominal Uncertainties in India

This paper examines the spillover effects and the causality between inflation, output growth and its uncertainties for India. Using monthly data for the period from April 1980 to April 2011, we estimated a bi-variate GARCH in mean with BEKK representations. This study differs from the earlier works where the parameters in the BEKK representations are estimated individually and the inferences are drawn on the basis of the individual lagged variance, covariance, and error terms from the respective equations. The empirical evidence suggests that inflation uncertainty seems to have significant negative impact on output growth and positive impact on output uncertainty and there is a positive influence of output uncertainty on the inflation. More importantly, there are spillovers and volatility transmission effects between the macroeconomic uncertainties where the volatility in output growth is significantly influenced by the shocks and volatility in inflation.
