  • Book cover of Inflation Targeting

    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.

  • Book cover of Welfare-maximizing Monetary Policy Under Parameter Uncertainty

    This paper examines welfare-maximizing monetary policy in an estimated micro-founded general equilibrium model of the U.S. economy where the policymaker faces uncertainty about model parameters. Uncertainty about parameters describing preferences and technology implies not only uncertainty about the dynamics of the economy. It also implies uncertainty about the model's utility-based welfare criterion and about the economy's natural rate measures of interest and output. We analyze the characteristics and performance of alternative monetary policy rules given the estimated uncertainty regarding parameter estimates. We find that the natural rates of interest and output are imprecisely estimated. We then show that, relative to the case of known parameters, optimal policy under parameter uncertainty responds less to natural-rate terms and more to other variables, such as price and wage inflation and measures of tightness or slack that do not depend on natural rates.

  • Book cover of Forecast-based Monetary Policy

    TThis article analyses the welfare consequences of delegating to the central bank the task of minimising deviations of forecasts of goal variables from their target values. The delegated objectives considered in this article are motivated by the observation that central banks oftentimes operate under objectives which do not necessarily represent society's preferences. The analysis is performed using an estimated model of optimising households and firms that generates tradeoffs between stabilising wage and price inflation and the output gap. We find that when the central bank's objective is defined solely in terms of price inflation, it is welfare optimal to stabilise only those fluctuations in price inflation that are forecastable at least five quarters ahead. On the other hand, when the central bank's objective involves both wage and price inflation stabilisation, the central bank should stabilise all fluctuations in these variables, not just those forecastable at some horizon.least five quarters ahead. On the other hand, when the central bank's objective involves both wage and price inflation stabilisation, the central bank should stabilise all fluctuations in these variables, not just those forecastable at some horizon.
