Ebook: Optional Monetary Policy Under Uncertainty

Recently there has been a resurgence of interest in the study of optimal monetary policy under uncertainty. This book provides a thorough survey of the literature that has resulted from this renewed interest. The authors ground recent contributions on the `science of monetary policy' in the literature of the 1970s, which viewed optimal monetary policy as primarily a question of the best use of information, and studies in the 1980s that gave primacy to time inconsistency problems. This broad focus leads to a better understanding of current issues such as discretion versus commitment, target versus instrument rules, and the merits of delegation of policy authority. Casting a wide net, the authors survey the recent literature on the New Keynesian approach to optimal monetary policy in the context of the earlier literature. They emphasize the relationship between policy decisions and the information set available to the policymaker, a central focus of the earlier literature, obscured in much recent work. Optimal policy questions are considered in open as well as closed economy models and the often confusing terminology in the literature is sorted and clarified. Questions are considered within easily analysed models and the authors clearly show why these models lead to different (or equivalent) policy conclusions. Recent policy issues such as desirability of inflation targeting and the relative merits of target versus instrument rules are covered in detail. Economists in academia and in policymaking organizations who want to learn about recent developments in the area of optimal monetary policy, as well as graduate and advanced undergraduate students in macroeconomic and monetary economics, will find this volume a clear and thorough examination of the topic.
