Economists have long debated the theoretical merits—for an individual nation and for a multi-nation world economy—of alternative approaches to the conduct of economic policy. Yet theory alone cannot resolve the important issues at stake. Only after the robustness of policy regimes has been carefully examined with empirical evidence will policymakers and economists be able to reach more of a consensus. This pathbreaking volume takes major steps forward in meeting the need for a combination of theoretical and empirical evaluations of alternative policy regimes. Bringing together individuals and groups doing pioneering research on macroeconomic interaction, it explores what approach to monetary policy would lead to superior performance by individual national economies and the world economy as a whole. Many parts of the book use the analytical techniques of stochastic simulation, an evaluation procedure increasingly employed at the frontier of empirical economic analysis. The book provides a summary of the hey issues involved in evaluating policy regimes and clarifies the relationships among those issues. The authors examine the stabilization properties of alternative monetary-policy regimes and analyze how well various regime types perform in the face of unexpected shocks to national economies. Among their conclusions, they find that some simplified regimes for monetary policy are markedly less promising than others for achieving the stabilization objectives commonly sought by policymakers. Evaluating Policy Regimes is another major installment in a continuing world wide research project, sponsored by the Brookings Institution, to improve empirical knowledge about the interdependence of national economies.

This book draws together the seminal contributions to the literature on the nature of macroeconomics in open economies and illuminates the material. This is an essential guide to the subject for students.

Much recent analysis of international monetary and fiscal policy issues, such as the choice of an exchange-rate regime or the design of a policy coordination scheme, has been conducted by stochastic simulations with multicountry econometric models. In these studies, it has become standard practice to consider alternative policy rules of a particular form that calls for departures of a policy instrument, from some “baseline” reference path, that are proportional to deviations of a specified target variable from its own baseline path. The present paper argues, however, that this standard rule form is seriously defective for evaluating such issues because the implied rules (1) often fail to be operational and (2) have associated performance measures that can be misleading in important cases. An example is presented that concerns the international “assignment problem” of optimally pairing instruments with policy objectives.

In this book David Currie and Paul Levine address a broad range of issues concerning the design and conduct of macroeconomic policy in open economies. Adopting neo-Keynesian models for which monetary and fiscal policy have short-term real effects, they analyse active stabilisation policies in both a single- and multi-country context. Questions addressed include: the merits of simple policy rules, policy design in the face of uncertainty and international policy coordination. A central feature of the book is the treatment of credibility and the effect of a policy-maker's reputation for sticking to announced policies. These considerations are integrated with coordination issues to produce a unique synthesis. The volume develops optimal control methods and dynamic game theory to handle relationships between governments and a conscious rational private sector and produces a unified, coherent approach to the subject. This book will be of interest to students and teachers of open economy macroeconomics and to professional economists interested in using macroeconomic models to design policy.
