Understanding Inflation And The Implications For Monetary Policy

Current perspectives on the Phillips curve, a core macroeconomic concept that treats the relationship between inflation and unemployment. In 1958, economist A. W. Phillips published an article describing what he observed to be the inverse relationship between inflation and unemployment; subsequently, the “Phillips curve” became a central concept in macroeconomic analysis and policymaking. But today's Phillips curve is not the same as the original one from fifty years ago; the economy, our understanding of price setting behavior, the determinants of inflation, and the role of monetary policy have evolved significantly since then. In this book, some of the top economists working today reexamine the theoretical and empirical validity of the Phillips curve in its more recent specifications. The contributors consider such questions as what economists have learned about price and wage setting and inflation expectations that would improve the way we use and formulate the Phillips curve, what the Phillips curve approach can teach us about inflation dynamics, and how these lessons can be applied to improving the conduct of monetary policy.

. . . this book provides a useful overview of the challenges facing the IT policy framework, both by pointing to the limitations of the underlying theory and, more importantly, by outlining the importance of a transparent policy framework for anchoring expectations. . . the book should be of interest to all central bankers and students of monetary policy. Colin Rogers, Economic Record Recent developments in macroeconomic and monetary thinking have given a new impetus to the management of the economy. The use of monetary policy by way of manipulating the rate of interest to affect inflation is now well accepted by both academic economists and central bank practitioners. Beginning with an assessment of new thinking in macroeconomics and monetary theory, this book suggests that many countries have adopted the New Consensus Monetary Policy since the early 1990s in an attempt to reduce inflation to low levels. It goes on to illustrate that the explicit control of the money supply, which was fashionable in the 1970s and 1980s in the UK, US, Europe and elsewhere, was abandoned in favour of monetary rules that focus on interest rate manipulation by the central bank. The objective of these rules is to achieve specific, or a range of, inflation targets. Bringing together a distinguished cast of international contributors, this book presents a collection of papers, which discuss the following issues amongst others: the stability of the macroeconomic equilibrium monetary policy divergences in the Euro area stock market prices the US post- new economy bubble the information economy inflation targeting. This useful analysis of New Consensus Monetary Policy will be of great interest to financial economists and international monetary economists, as well as students and scholars of macroeconomics and finance.

We explore two issues triggered by the crisis. First, in most advanced countries, output remains far below the pre-recession trend, suggesting hysteresis. Second, while inflation has decreased, it has decreased less than anticipated, suggesting a breakdown of the relation between inflation and activity. To examine the first, we look at 122 recessions over the past 50 years in 23 countries. We find that a high proportion of them have been followed by lower output or even lower growth. To examine the second, we estimate a Phillips curve relation over the past 50 years for 20 countries. We find that the effect of unemployment on inflation, for given expected inflation, decreased until the early 1990s, but has remained roughly stable since then. We draw implications of our findings for monetary policy.

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.

Edited and with an introduction by Benjamin M. Friedman The connection between price inflation and real economic activity has been a focus of macroeconomic research--and debate--for much of the past century. Although this connection is crucial to our understanding of what monetary policy can and cannot accomplish, opinions about its basic properties have swung widely over the years. Today, virtually everyone studying monetary policy acknowledges that, contrary to what many modern macroeconomic models suggest, central bank actions often affect both inflation and measures of real economic activity, such as output, unemployment, and incomes. But the nature and magnitude of these effects are not yet understood. In this volume, Robert M. Solow and John B. Taylor present their views on the dilemmas facing U.S. monetary policymakers. The discussants are Benjamin M. Friedman, James K. Galbraith, N. Gregory Mankiw, and William Poole. The aim of this lively exchange of views is to make both an intellectual contribution to macroeconmics and a practical contribution to the solution of a public policy question of central importance.

Controlling inflation is among the most important objectives of economic policy. By maintaining price stability, policy makers are able to reduce uncertainty, improve price-monitoring mechanisms, and facilitate more efficient planning and allocation of resources, thereby raising productivity. This volume focuses on understanding the causes of the Great Inflation of the 1970s and ’80s, which saw rising inflation in many nations, and which propelled interest rates across the developing world into the double digits. In the decades since, the immediate cause of the period’s rise in inflation has been the subject of considerable debate. Among the areas of contention are the role of monetary policy in driving inflation and the implications this had both for policy design and for evaluating the performance of those who set the policy. Here, contributors map monetary policy from the 1960s to the present, shedding light on the ways in which the lessons of the Great Inflation were absorbed and applied to today’s global and increasingly complex economic environment.

Inflation is regarded by the many as a menace that damages business and can only make life worse for households. Keeping it low depends critically on ensuring that firms and workers expect it to be low. So expectations of inflation are a key influence on national economic welfare. This collection pulls together a galaxy of world experts (including Roy Batchelor, Richard Curtin and Staffan Linden) on inflation expectations to debate different aspects of the issues involved. The main focus of the volume is on likely inflation developments. A number of factors have led practitioners and academic observers of monetary policy to place increasing emphasis recently on inflation expectations. One is the spread of inflation targeting, invented in New Zealand over 15 years ago, but now encompassing many important economies including Brazil, Canada, Israel and Great Britain. Even more significantly, the European Central Bank, the Bank of Japan and the United States Federal Bank are the leading members of another group of monetary institutions all considering or implementing moves in the same direction. A second is the large reduction in actual inflation that has been observed in most countries over the past decade or so. These considerations underscore the critical – and largely underrecognized - importance of inflation expectations. They emphasize the importance of the issues, and the great need for a volume that offers a clear, systematic treatment of them. This book, under the steely editorship of Peter Sinclair, should prove very important for policy makers and monetary economists alike.
