The problems of exchange rate misalignments and the resulting payments imbalances have plagued the world economy for decades. At the Louvre Accord of 1987, the Group of Five industrial countries adopted a system of reference ranges for exchange rate management, influenced by proposals of C. Fred Bergstan and John Williamson for a target zone system. The reference range approach has, however, been operated only intermittently and half-heartedly, and questions continue to be raised in policy and scholarly circles about the design and operation of a full-fledged target zone regime. This volume, with chapters by leading international economists, explores one crucial issue in the design of a target zone system: the problem of calculating Williamson's concept of the fundamental equilibrium exchange rate (FEER). Williamson contributes an overview of the policy and analytic issues and a second chapter on his own calculations.

How successful is PPP, and its extension in the monetary model, as a measure of the equilibrium exchange rate? What are the determinants and dynamics of equilibrium real exchange rates? How can misalignments be measured, and what are their causes? What are the effects of specific policies upon the equilibrium exchange rate? The answers to these questions are important to academic theorists, policymakers, international bankers and investment fund managers. This volume encompasses all of the competing views of equilibrium exchange rate determination, from PPP, through other reduced form models, to the macroeconomic balance approach. This volume is essentially empirical: what do we know about exchange rates? The different econometric and theoretical approaches taken by the various authors in this volume lead to mutually consistent conclusions. This consistency gives us confidence that significant progress has been made in understanding what are the fundamental determinants of exchange rates and what are the forces operating to bring them back in line with the fundamentals.

Economists writing on flexible exchange rates in the 1960s foresaw neither the magnitude nor the persistence of the changes in real exchange rates that have occurred in the last fifteen years. Unexpectedly large movements in relative prices have lead to sharp changes in exports and imports, disrupting normal trading relations and causing shifts in employment and output. Many of the largest changes are not equilibrium adjustments to real disturbances but represent instead sustained departures from long-run equilibrium levels, with real exchange rates remaining "misaligned" for years at a time. Contributors to Misalignment of Exchange Rates address a series of questions about misalignment. Several papers investigate the causes of misalignment and the extent to which observed movements in real exchange rates can be attributed to misalignment. These studies are conducted both empirically, through the experiences of the United States, Great Britain, Japan, and the countries of the European Monetary System, and theoretically, through models of imperfect competition. Attention is then turned to the effects of misalignment, especially on employment and production, and to detailed estimates of the effects of changes in exchange rates on several industries, including the U.S. auto industry. In response to the contention that there is significant "hysteresis" in the adjustment of employment and production to changes in exchange rates, contributors also attempt to determine whether the effects of misalignment can be reversed once exchange rates return to earlier levels. Finally, the issue of how to avoid—or at least control—misalignment through macroeconomic policy is confronted.

''In summary, the book is valuable as a textbook both at the advanced undergraduate level and at the graduate level. It is also very useful for the economist who wants to be brought up-to-date on theoretical and empirical research on exchange rate behaviour.'' ""Journal of International Economics""

This book collects together the basic documents of an approach to the theory and policy of the balance of payments developed in the 1970s. The approach marked a return to the historical traditions of international monetary theory after some thirty years of departure from them – a departure occasioned by the international collapse of the 1930s, the Keynesian Revolution and a long period of war and post-war reconstruction in which the international monetary system was fragmented by exchange controls, currency inconvertibility and controls over international trade and capital movements.

The study cautiously identifies exchange rate misalignment as an important element in most of the exchange rate crises that plagued the developing world during the last decade. Given that the increasing integration of world capital markets, has escalated the costs of such crises, a broad consensus emerged in recent years, that the overriding objective of exchange rate policy in developing countries, should be to avoid episodes of prolonged, and substantial misalignment, i.e., situations in which the actual real exchange rate differs significantly from its long-run equilibrium value. It was the Bank's involvement in one such misalignment episode, that eventually led to this book. Following an overview on the concepts and measurement of exchange rate misalignment, its impact on the purchasing power parity, and the relationship between the external real exchange rate (RER), and the two-good internal RER for tradables non-tradables, the study presents methodologies - empirical applications - for estimating the RER equilibrium. The study reaches an optimistic conclusion - that enough is known to identify cases of misalignment, and be able to sound clear warning signals. The implication for exchange rate policy is that ignorance about the empirical value of the equilibrium exchange rate, cannot be used to clinch arguments for extreme exchange arrangements, such as clean floats, currency boards, and "dollarization."
