Volatile exchange rates and how to manage them are a contentious topic whenever economic policymakers gather in international meetings. This book examines the broad parameters of exchange rate policy in light of both high-powered theory and real-world experience. What are the costs and benefits of flexible versus fixed exchange rates? How much of a role should the exchange rate play in monetary policy? Why don't volatile exchange rates destabilize inflation and output? The principal finding of this book is that using monetary policy to fight exchange rate volatility, including through the adoption of a fixed exchange rate regime, leads to greater volatility of employment, output, and inflation. In other words, the "cure" for exchange rate volatility is worse than the disease. This finding is demonstrated in economic models, in historical case studies, and in statistical analysis of the data. The book devotes considerable attention to understanding the reasons why volatile exchange rates do not destabilize inflation and output. The book concludes that many countries would benefit from allowing greater flexibility of their exchange rates in order to target monetary policy at stabilization of their domestic economies. Few, if any, countries would benefit from a move in the opposite direction.

A growing number of countries are adopting flexible exchange rate regimes because flexibility offers more protection against external shocks and greater monetary independence. Other countries have made the transition under disorderly conditions, with the sharp depreciation of their currency during a crisis. Regardless of the reason for adopting a flexible exchange rate, a successful transition depends on the effective management of a number of institutional and operational issues. The authors of this Economic Issue describe the necessary ingredients for moving to a flexible regime, as well as the optimal pace and sequencing under different conditions.

This book describes the remarkable path which led to the Swiss Franc becoming the strong international currency that it is today. Ernst Baltensperger and Peter Kugler use Swiss monetary history to provide valuable insights into a number of issues concerning the organization and development of monetary institutions and currency that shaped the structure of financial markets and affected the economic course of a country in important ways. They investigate a number of topics, including the functioning of a world without a central bank, the role of competition and monopoly in money and banking, the functioning of monetary unions, monetary policy of small open economies under fixed and flexible exchange rates, the stability of money demand and supply under different monetary regimes, and the monetary and macroeconomic effects of Swiss Banking and Finance. Swiss Monetary History since the Early 19th Century illustrates the value of monetary history for understanding financial markets and macroeconomics today.

China’s exchange rate regime has undergone gradual reform since the move away from a fixed exchange rate in 2005. The renminbi has become more flexible over time but is still carefully managed, and depth and liquidity in the onshore FX market is relatively low compared to other countries with de jure floating currencies. Allowing a greater role for market forces within the existing regime, and greater two-way flexibility of the exchange rate, are important steps to build on the progress already made. This should be complemented by further steps to develop the FX market, improve FX risk management, and modernize the monetary policy framework.

Many countries have moved towards more flexible exchange rate regimes over the last decade to take advantage of greater monetary policy autonomy and flexibility in responding to external shocks. Some reluctance to let go of pegged exchange rates persists, however, despite the benefits of flexibility. The institutional and operational requirements needed to support a floating exchange rate, as well as difficulties in assessing the right time and manner to exit, tend to be additional factors in this reluctance. This volume presents the concrete steps taken by a number of countries in transition to greater exchange rate flexibility and elaborates on the operational ingredients that proved helpful in promoting successful and durable transitions. It attempts to provide a better understanding (and hence a "road map") of how these various operational ingredients were established and coordinated, how their implementation interacted with macro and other conditions, and how they contributed to the smoothness of each transition.

''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""
