The Inflation Targeting Debate

Over the past fifteen years, a significant number of industrialized and middle-income countries have adopted inflation targeting as a framework for monetary policymaking. As the name suggests, in such inflation-targeting regimes, the central bank is responsible for achieving a publicly announced target for the inflation rate. While the objective of controlling inflation enjoys wide support among both academic experts and policymakers, and while the countries that have followed this model have generally experienced good macroeconomic outcomes, many important questions about inflation targeting remain. In Inflation Targeting, a distinguished group of contributors explores the many underexamined dimensions of inflation targeting—its potential, its successes, and its limitations—from both a theoretical and an empirical standpoint, and for both developed and emerging economies. The volume opens with a discussion of the optimal formulation of inflation-targeting policy and continues with a debate about the desirability of such a model for the United States. The concluding chapters discuss the special problems of inflation targeting in emerging markets, including the Czech Republic, Poland, and Hungary.

Inflation targeting (IT) has gained much traction over the past two decades, becoming a framework of reference for the conduct of monetary policy. However, the debate about its very merits and macroeconomic consequences remains inconclusive. This paper digs deeper into the issue through a meta-regression analysis (MRA) of the existing literature, making it the first application of a MRA to the macroeconomic effects of IT adoption. Building on 8,059 estimated coefficients from a very broad sample of 113 studies, the paper finds that the empirical literature suffers from two types of publication bias. First, authors, editors and reviewers prefer results featuring beneficial effects of IT adoption on inflation volatility, real GDP growth and fiscal performances; second, they promote results with estimated coefficients that are significantly different from zero. However, after filtering out the publication biases, we still find meaningful (genuine) effects of IT in reducing inflation and real GDP growth volatility, but no significant genuine effects on inflation volatility and the level of real GDP growth. Interestingly, the results indicate that the impact of IT varies systematically across studies, depending on the sample structure and composition, the time coverage, the estimation techniques, country-specific factors, IT implementation parameters, and publication characteristics.

Since the financial crisis of 2008/09, the world’s major central banks have been struggling to return their economies to higher growth and to reach their inflation targets. This concise book analyzes the importance of central bank policies for the economy, and specifically investigates the reasons why they have failed to steer inflation as desired. The author, the Chief Economist at Allianz SE, argues that, in an environment of great uncertainty concerning the pass-through of monetary stimulus to the economy, central banks should not focus too narrowly on inflation targets, but should increasingly take the side effects of their actions into account. In particular, he contends that they must seek to minimize the risk of financial booms and busts in order to maximize long-term growth and prosperity. Building on existing research and contributing to the current debate, the book offers a valuable reference guide and food for thought for policymakers, professionals and students alike.

How should governments and central banks use monetary policy to create a healthy economy? Traditionally, policymakers have used such strategies as controlling the growth of the money supply or pegging the exchange rate to a stable currency. In recent years a promising new approach has emerged: publicly announcing and pursuing specific targets for the rate of inflation. This book is the first in-depth study of inflation targeting. Combining penetrating theoretical analysis with detailed empirical studies of countries where inflation targeting has been adopted, the authors show that the strategy has clear advantages over traditional policies. They argue that the U.S. Federal Reserve and the European Central Bank should adopt this strategy, and they make specific proposals for doing so. The book begins by explaining the unique features and advantages of inflation targeting. The authors argue that the simplicity and openness of inflation targeting make it far easier for the public to understand the intent and effects of monetary policy. This strategy also increases policymakers' accountability for inflation performance and can accommodate flexible, even "discretionary," monetary policy actions without sacrificing central banks' credibility. The authors examine how well variants of this approach have worked in nine countries: Germany and Switzerland (which employ a money-focused form of inflation targeting), New Zealand, Canada, the United Kingdom, Sweden, Israel, Spain, and Australia. They show that these countries have typically seen lower inflation, lower inflation expectations, and lower nominal interest rates, and have found that one-time shocks to the price level have less of a "pass-through" effect on inflation. These effects, in turn, are improving the climate for economic growth. The authors warn, however, that the success of inflation targeting depends on operational details, such as how the targets are defined and when they are announced. They also show that inflation targeting is not a panacea that can make inflation perfectly predictable or reduce it without economic costs. Clear, balanced, and authoritative, Inflation Targeting is a groundbreaking study that will have a major impact on the debate over the right monetary strategy for the coming decades. As a unique comparative study of what central banks actually do in different countries around the world, this book will also be invaluable to anyone interested in how economic policy is made.

This paper investigates the meaning of the bottom of target bands in inflation targeting regimes. It is argued that the design of lower limits on target bands, if not done with care, can lead to a lack of transparency, potentially confusing markets about how the authorities will react to a fall in inflation. After first discussing the conceptual issues, the paper then examines the experience with target bands in New Zealand, Israel and Canada and explores how the conceptual issues have played out in practice.

As with many monetary policy frameworks, inflation targeting is subject to the well-known problem of inflation bias. With inflation targeting, however, the bias becomes apparent not as inflation above desired levels, but as a wedge between the announced target and observed inflation. This inconsistency could render the framework neither credible nor enforceable since the target is overshot on average. The problem can be addressed by assigning price stability as the single policy objective or by assigning a joint target for both inflation and output, provided that they are consistent. Many inflation targeting countries take the joint target approach implicitly through transparency measures which publicly assess monetary conditions in terms of potential output and output gaps.

This paper asks whether inflation targeting improves economic performance, as measured by the behavior of inflation, output, and interest rates. We compare seven OECD countries that adopted inflation targeting in the early 1990s to thirteen that did not. After the early 90s, performance improved along many dimensions for both the targeting countries and the non-targeters. In some cases the targeters improved by more; for example, average inflation fell by a larger amount. However, these differences are explained by the facts that targeters performed worse than non-targeters before the early 90s, and there is regression to the mean. Once one controls for regression to the mean, there is no evidence that inflation targeting improves performance.

This is the second chapter of a forthcoming monograph entitled "On Implementing Full-Fledged Inflation-Targeting Regimes: Saying What You Do and Doing What You Say." We begin by discussing the costs of inflation, including their role in generating boom-bust cycles. Following a general discussion of the need for a nominal anchor, we describe a specific type of monetary anchor, the inflation-targeting regime, and its two key intellectual roots-the absence of long-run trade-offs and the time-inconsistency problem. We conclude by providing a brief introduction to the way in which inflation targeting works.
