通货膨胀目标制实践经验的国际考察

作为一种新型的货币政策制度框架,标准型通货膨胀目标制在全球的中央银行中已经获得了一定的认同.然而迄今为止,我们还缺乏一个对目前大量的通货膨胀目标制实践经验进行简洁而全面的概括,借以对货币政策的实践和通货膨胀目标钉住者的前景展望提供相应指南.而这种指南之所以必要,是因为队伍不断庞大的发展中国家和新兴市场经济体正在考虑是否采纳通货膨胀目标制.借鉴标准型通货膨胀目标制国家在控制通货膨胀过程中所积累的经验,探讨通货膨胀目标制国家面临的主要问题、发展趋势、政策实践,其目的是为了从国家的角度来思考是否应该采纳通货膨胀目标制;而对于已经实施通货膨胀目标制的国家,则要考虑如何健全这一制度框架.     

Inflation targeting and financial stability in emerging markets

This paper aims at investigating whether emerging market inflation targeters are more financially vulnerable than their non-targeting counterparts. It further assesses the extent to which targeting central banks are less responsive to financial imbalances, compared to those implementing alternative policy strategies. Based on a sample of 26 emerging countries, including 13 targeters, the analysis suggests that monetary policy in targeting countries is relatively more sensitive to financial risks. However, despite stronger central banks’ responses to financial imbalances, the financial sector appears to be more fragile for targeters. Our conclusion therefore challenges the view that central banks, through their policy interest rates, can guarantee the stability of the financial system. It rather suggests that the control of inflation should remain the primary monetary policy objective, while a (macro)prudential authority would be in charge of the financial stability objective.     

INFLATION TARGETING AND THE STATIONARITY OF INFLATION: NEW RESULTS FROM AN ESTAR UNIT ROOT TEST

In this paper, we examine the time series properties of inflation in seven countries that have adopted inflation targeting. Unlike previous studies, we utilize a non‐linear mean reverting adjustment mechanism for inflation and we discover that, although deviations of inflation from the target can exhibit a region of non‐stationary behaviour, overall they are stationary indicating successful targeting implementation.     

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.     

Inflation targeting and core inflation

Abstract.  This paper examines the interaction of core inflation and inflation targeting as a monetary policy regime. Interest in core inflation has grown because of inflation targeting. Core inflation is defined in numerous ways giving rise to many potential measures; this paper defines core inflation as the best forecaster of inflation. A cross‐country study finds before the start of inflation targeting, but not after, core inflation differs between non‐inflation targeters and inflation targeters. Through conditional regressions, inflation expectations as measured by core inflation have not changed with the advent of inflation targeting nor do they differ from non‐targeters.

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.     

Inflation targeting in Brazil

The purpose of this paper is to examine the Inflation Targeting (IT) framework as it is applied in the case of Brazil since its adoption in June 1999. For this purpose we first summarize the macroeconometric model utilized by the Central Bank of Brazil (BCB) in its pursuit of the IT framework. While the focus of this paper is on Brazil, we also examine the experience of other countries with IT (in particular, the BRIC countries: Brazil, Russia, India, and China), both for comparative purposes and for evidence of the extent of success of this ‘new’ economic policy pursued by other IT countries. In addition, we compare the experience of Brazil with IT and with that of non‐IT countries. In the context of non‐IT countries, we ask the question of whether it makes a difference in the fight against inflation whether a country has adopted IT or not. Finally, we examine some features of the Brazilian experience with IT regime.     

The reaction of disagreements in inflation expectations to fiscal sentiment obtained from information in official communiqués

Using official communiqués about fiscal policy, we develop a fiscal sentiment indicator, and we verify the reaction of disagreements in inflation expectations to fiscal sentiment. This analysis is relevant to inflation targeting (IT) countries because transparency and communication can influence expectations. The results suggest that a more optimistic fiscal sentiment reduces disagreements in inflation expectations. Estimates show that, for higher disagreements in inflation expectations at 12-month maturity, an optimistic fiscal sentiment can reduce the disagreement more sharply. In turn, the fiscal sentiment effect on the disagreement for the 48-month maturity is stronger the smaller the disagreement is. The results allow us to outline the following policy recommendations. First, an optimistic fiscal environment is important in the task of guiding inflation expectations and reducing inflation uncertainty. Second, fiscal communication is an important tool for the expectations formation process, and therefore it must be carefully managed to help in the task of forward guidance of inflation expectations, being important for the IT regime. Third, both fiscal credibility and monetary policy credibility are important for the expectations formation process, particularly for the reduction of inflation uncertainty, representing aspects that must be preserved in countries that adopt the IT regime.     

LINKAGES BETWEEN EXCHANGE RATE POLICY AND MACROECONOMIC PERFORMANCE

Using a sample of 104 countries, we study macroeconomic performance from 1973 to 2007. We examine GDP growth, inflation rate, growth volatility and inflation volatility, and their response to a ‘words versus deeds’ measure of exchange‐rate policy, which is obtained by interacting a country's de jure and its de facto policy. For non‐industrialized countries, the highest growth rates and the lowest inflation volatility are associated with countries that pursue fear of floating policy, whereas countries that pursue a matched float policy (de jure and de facto floating) have the highest inflation rates but the lowest GDP volatility.     

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.     

Transitional price rises with the adoption of the euro: aggregate and disaggregate sector evidence

This paper presents a time‐series regression analysis of price inflation at the time of the euro currency changeover in January 2002. Cross‐equation tests on 12 euro countries and three non‐euro EU countries are used to identify significant price changes around that time. For a small number of product and service categories, positive price changes immediately after the euro changeover suggest the possible existence of menu costs, sellers' rounding up of prices or buyers' temporary rational inattention. However, the lack of evidence for reduced inflation immediately prior to the euro changeover suggests menu costs are not important.     

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.     

The enlargement of the euro area: differences in relative inflation

This paper investigates the structural determinants of relative inflation (i.e. the inflation of non‐tradables vs tradables) in the context of overall inflation differentials in the EU. The analysis is based on the Bergstrand theoretical model. This framework incorporates three alternative hypotheses of relative inflation (Harrod–Balassa–Samuelson, relative factors endowment, and demand effects). Due to the lack of reliable data on capital stocks only a curtailed version of the model is tested here empirically. The various specifications of the model are estimated for the majority of EU countries, using the Pedroni panel group mean FMOLS estimator. In general, relative labour productivity and demand factors turn out to be significant and correctly signed, though evidence in favour of the latter effect seems to be less robust. In addition, differences in the determination of relative prices between the new and old EU Member States are found. They seem to be consistent with theoretical considerations and the transition phenomenon. The estimation results are very sensitive to the definition of non‐tradables. The paper also discusses policy implications for overall inflation, stemming from relative price models. It questions the usefulness of relative inflation models for the analysis of overall inflation differentials and practical policy decisions.     

OPTIMAL MONETARY POLICY WITH THE STICKY INFORMATION MODEL OF PRICE ADJUSTMENT: INFLATION OR PRICE‐LEVEL TARGETING?

I investigate the optimal monetary policy in a New Keynesian macroeconomic framework with the sticky information model of price adjustment. The model is solved for optimal policy, and welfare implications of three alternative monetary policy regimes under this optimal policy are compared when there is a cost‐push shock to the economy. These monetary policy regimes are the unconstrained policy, price‐level targeting and inflation targeting regimes. The results illustrate that optimal policy depends on the degree of price stickiness and the persistence of the shock. Inflation targeting emerges as the optimal policy if prices are flexible enough or the shock is persistent enough. However, the unconstrained policy or price‐level targeting might be preferable to inflation targeting if prices are not very flexible and the shock is not very persistent. The results also show that as prices become more flexible, the welfare loss usually gets bigger.

The impact of inflation targeting: Testing the good luck hypothesis

Starting in the mid‐1980s, the level and volatility of inflation decreased across industrial countries. The inflation stabilization can be explained by a shift in monetary policy or by a lucky period of low volatility in business cycle shocks. To test the “good luck hypothesis,” we examine the inflation experience of Canada, one of the earliest and most successful adopters of an inflation targeting monetary policy. We Kalman‐filter the historical structural shocks consistent with an estimated dynamic stochastic general equilibrium (DSGE) model of the Canadian economy. The estimated shocks are used to build counterfactual histories. The good luck hypothesis can explain only a minor portion of the change in the path and volatility of inflation after the shift in policy. Most of inflation and output stabilization is accounted by the impact on expectations. Unconditionally, the inflation targeting policy does not improve on the previous policy in terms of inflation volatility, but supports a more favourable trade‐off, reducing substantially output volatility.     

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.

Does inflation targeting make a difference in developing countries?

We evaluate the treatment effect of inflation targeting in thirteen developing countries that have adopted this policy by the end of 2004. Using a variety of propensity score matching methods, we show that, on average, inflation targeting has large and significant effects on lowering both inflation and inflation variability in these thirteen countries. However, the effectiveness of inflation targeting on lowering inflation is found to be quite heterogeneous. The performance of a given inflation targeting regime can be affected by country characteristics such as government's fiscal position, central bank's desire to limit the movements of exchange rate, its willingness to meet the preconditions of policy adoption, and the time length since the policy adoption.     

Inflation convergence in Central and Eastern Europe vs. the Eurozone: Non‐linearities and long memory

In this paper, we consider inflation rate differentials between seven Central and Eastern European Countries (CEECs) and the Eurozone. We test for convergence in the inflation rate differentials, incorporating non‐linearities in the autoregressive parameters, fractional integration with endogenous structural changes, and also consider club convergence analysis for the CEECs over the period 1997 to 2015 based on monthly data. Our empirical findings suggest that the majority of countries experience non‐linearities in the inflation rate differential; however, there is only evidence of a persistent difference in some countries. Complementary to this analysis we apply the Phillips and Sul (2007) test for club convergence and find that there is evidence that most of the CEECs converge to a common steady state.     

RIGHT ON TARGET: EXPLORING THE FACTORS LEADING TO INFLATION TARGETING ADOPTION

This paper examines which economic, fiscal, external, financial, and institutional characteristics of countries affect the likelihood that they adopt inflation targeting (IT) as their monetary policy strategy. We estimate a panel binary response model for 60 countries and two subsamples consisting of Organization for Economic Cooperation and Development (OECD) and non‐OECD countries over the period 1985–2008. The findings suggest that past macroeconomic performance of a country, its fiscal discipline, exchange rate arrangements, as well as the structure and development of its financial system have a significant impact on the likelihood to adopt IT. However, the factors leading to IT adoption differ significantly between OECD and non‐OECD countries. (JEL E42, E52)
