Why we need to heed the lessons of high inflation Today's global economy, with most developed nations experiencing very low inflation, seems a world apart from the "Great Inflation" that spanned the late 1960s to early 1980s. Yet, in this book, Brigitte Granville makes the case that monetary economists and policymakers need to keep the lessons learned during that period very much in mind, lest we return to them by making the same mistakes we made in the past. Granville details the advances in macroeconomic thinking that gave rise to the "Great Moderation"—a period of stable inflation and economic growth, which lasted from the mid-1980s through the most recent financial crisis. She makes the case that the central banks' management of monetary policy—hinging on expectations and credibility—brought about this period of stability, and traces the roots of this success back to the eighteenth-century foundations of modern monetary thought. Tackling fundamental questions such as the causes of inflation and its relation to unemployment and growth, the natural rate of inflation hypothesis, the fiscal theory of the price level, and the proper goals of central banks, the book aims above all to demonstrate the dangers of forgetting the role of credibility in establishing sound monetary policy. With the lessons of the past firmly in mind, Granville presents stimulating ideas and proposals about inflation-targeting principles, which provide tools for present-day monetary authorities dealing with the forces of globalization, mercantilism, and reserve accumulation.

This book deals with the key aspects of developments in monetary economics and macroeconomics, such as the New Consensus Macroeconomics, and further ones such as money, credit and the business cycle. Adding to the analysis are developments that focus on issues for open and spatial macroeconomics.

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.

Yes, it makes a lot of sense. This paper studies how to design simple loss functions for central banks, as parsimonious approximations to social welfare. We show, both analytically and quantitatively, that simple loss functions should feature a high weight on measures of economic activity, sometimes even larger than the weight on inflation. Two main factors drive our result. First, stabilizing economic activity also stabilizes other welfare relevant variables. Second, the estimated model features mitigated inflation distortions due to a low elasticity of substitution between monopolistic goods and a low interest rate sensitivity of demand. The result holds up in the presence of measurement errors, with large shocks that generate a trade-off between stabilizing inflation and resource utilization, and also when ensuring a low probability of hitting the zero lower bound on interest rates.
