Book Description
Abstract: This paper derives loss functions for monetary policy that are grounded in the welfare of private agents, for optimizing models with nominal price rigidities. Inflation stabilization enhances welfare, insofar as variable inflation results in real distortions when prices are not adjusted throughout the economy in a perfectly synchronized fashion. The exact sense in which inflation variability matters for welfare, however, depends upon the details of price-setting behavior. Conditions are described under which optimal policy involves complete stabilization of the price level. This may be optimal even in the presence of 'supply shocks' of several possible sorts, and even in the presence of distortions that imply that the optimal output gap is positive (despite existence of a long-run Phillips curve). At the same time discussed why complete price-level stabilization is not optimal in more complicated (and probably more realistic) settings.

Book Description
"This paper considers the appropriate stabilization objectives for monetary policy in a microfounded model with staggered price-setting. Rotemberg and Woodford (1997) and Woodford (2002) have shown that under certain conditions, a local approximation to the expected utility of the representative household in a model of this kind is related inversely to the expected discounted value of a conventional quadratic loss function, in which each period's loss is a weighted average of squared deviations of inflation and an output gap measure from their optimal values (zero). However, those derivations rely on an assumption of the existence of an output or employment subsidy that offsets the distortion due to the market power of monopolistically-competitive price-setters, so that the steady state under a zero-inflation policy involves an efficient level of output. Here we show how to dispense with this unappealing assumption, so that a valid linear-quadratic approximation to the optimal policy problem is possible even when the steady state is distorted to an arbitrary extent (allowing for tax distortions as well as market power), and when, as a consequence, it is necessary to take account of the effects of stabilization policy on the average level of output. We again obtain a welfare-theoretic loss function that involves both inflation and an appropriately defined output gap, though the degree of distortion of the steady state affects both the weights on the two stabilization objectives and the definition of the welfare-relevant output gap. In the light of these results, we reconsider the conditions under which complete price stability is optimal, and find that they are more restrictive in the case of a distorted steady state. We also consider the conditions under which pure randomization of monetary policy can be welfare-improving, and find that this is possible in the case of a sufficiently distorted steady state, though the parameter values required are probably not empirically realistic"--National Bureau of Economic Research web site.

Book Description
In recent years, the Federal Reserve and central banks worldwide have enjoyed remarkable success in their battle against inflation. The challenge now confronting the Fed and its counterparts is how to proceed in this newly benign economic environment: Should monetary policy seek to maintain a rate of low-level inflation or eliminate inflation altogether in an effort to attain full price stability? In a seminal article published in 1997, Martin Feldstein developed a framework for calculating the gains in economic welfare that might result from a move from a low level of inflation to full price stability. The present volume extends that analysis, focusing on the likely costs and benefits of achieving price stability not only in the United States, but in Germany, Spain, and the United Kingdom as well. The results show that even small changes in already low inflation rates can have a substantial impact on the economic performance of different countries, and that variations in national tax rules can affect the level of gain from disinflation.

Book Description
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.

Book Description
This article considers recent literature on optimal monetary policy in simple open-economy models. The presence of pricing to market, incomplete financial markets, and differences in preferences among households (in different countries) introduces some fundamental differences between closed- and open-economy New Keynesian models. In addition to the goals of stabilizing inflation and the output gap, policy makers may target currency misalignments and global imbalances. Optimal policies may involve targeting the exchange rate both directly, because of currency misalignments, and indirectly, because of the effects of exchange rates on imbalances, inflation, and output gaps.

Book Description
In view of the widely recognized costs of inflation, in terms of both its propensity to endanger macroeconomic stability in the short run and its possible harmful effects on growth in the longer term, reducing inflation has long been a top priority of most policy makers. Looking at recent global inflation experiences, it can arguably be said that, on the whole, substantial headway on this front has been made. In most industrialized countries, as well as in a large number of Asian countries (prior to the current crisis), inflation has dropped to below 5 percent. Even in many other developing economies, including Latin American countries, inflation has been brought down to low double-digit levels in recent years. If and when inflation in a country has reached a relatively low level, would it still be desirable for policy makers to vigorously pursue, or target, complete price stability as an ultimate policy goal?

Book Description
This paper develops a model of inflation inertia based on optimizing forward looking staggered price setting in a small open economy. Unlike in current models of sticky prices, transitions to a lower steady state inflation rate take time even if they are fully credible, and they are associated with significant output losses. There is a welfare trade-off between these output losses and the gains from smaller inflationary distortions. For reasonable parameter values inflation stabilization improves welfare. The optimal steady state is reached at the Friedman rule. Technical appendices are available at www.nber.org/data-appendix/w9557/ inert-techapp.pdf.
