An analysis of the operation and consequences of exchange rate regimes in an era of increasing international interdependence. The exchange rate is sometimes called the most important price in a highly globalized world. A country's choice of its exchange rate regime, between government-managed fixed rates and market-determined floating rates has significant implications for monetary policy, trade, and macroeconomic outcomes, and is the subject of both academic and policy debate. In this book, two leading economists examine the operation and consequences of exchange rate regimes in an era of increasing international interdependence. Michael Klein and Jay Shambaugh focus on the evolution of exchange rate regimes in the modern era, the period since 1973, which followed the Bretton Woods era of 1945-72 and the pre-World War I gold standard era. Klein and Shambaugh offer a comprehensive, integrated treatment of the characteristics of exchange rate regimes and their effects. The book draws on and synthesizes data from the recent wave of empirical research on this topic, and includes new findings that challenge preconceived notions.

This paper investigates the effects of fixed versus flexible exchange rates on firms’ location choices and on countries’ specialization patterns. In a two-country, two-differentiated-goods monetary model, demand, supply, and monetary (as well as exchange rate) shocks arise after wages are set and prices are optimally chosen. The paper finds that countries are more specialized under flexible than fixed rates, and that the pattern of specialization is not uniquely defined by trade models but depends also on the exchange rate regime. The adoption of fixed exchange rates endogenously increases the desirability of this currency area by reducing the shock asymmetry. These results also shed light on the effects of exchange rate variability on trade.

Most of the literature on exchange rate regimes has focused on the developed countries. Since the recent crises in emerging markets, however, attention has shifted to the choice of exchange rate regimes for developing countries, especially those that are more integrated into the world capital markets. In Too Sensational, W. Max Corden presents a systematic and accessible overview of the choice of exchange rate regimes. Reviewing many types of regimes, he shows how the choice of an exchange rate regime is related to both fiscal policy and trade policy. Building on the theory of optimum currency areas, Corden develops an analytic framework of three approaches (nominal anchor, real targets, and exchange rate stability) and three polar exchange rate regimes (absolutely fixed, pure floating, and fixed but adjustable). He considers all other regimes to be mixtures of two or three of the polar regimes. Beginning with theory and later turning to case studies of countries in Asia, Europe, and Latin America, Corden focuses on how economies react to negative and positive shocks under various exchange rate regimes. He examines in particular the Asian and Latin American currency crises of the 1990s. He concludes that although "too sensational" crises have discredited fixed but adjustable regimes, the extremes of absolutely fixed regimes or pure floating regimes need not be chosen.

In the aftermath of the Asian/global financial crises of 1997-98, how should emerging markets now structure their exchange rate systems to prevent new crises from occurring? This study challenges current orthodoxy by advocating the revival of intermediate exchange rate regimes. In so doing, Williamson presents a reasoned challenge to the new prevailing attitude which claims that all countries involved in the international capital markets need to polarize to one of the extreme regimes (to a fixed rate with either a currency board or dollarization, or to a lightly-managed float). He concludes that although there is some truth in the allegation that intermediate regimes are vulnerable to speculative crises, they still offer offsetting advantages. He also contends that it would be possible to redesign them to be more flexible so as to reduce their vulnerability to crises.

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.

This study examines in detail the experiences of three countries that have in recent years operated exchange rate systems of "crawling bands," similar in spirit to the target zones that the author has recommended in the past. Williamson compares the succcessful experiences of 3 countries that have operated crawling bands with 15 similar countries and concludes that the crawling band exchange-rate policy has been an important element in their success. The study includes a manual for managing crawling bands.

The Asian crisis of 1997-1998 was a major influence on macroeconomic thinking concerning exchange rate regimes, the functioning of international institutions, such as the IMF and the World Bank, and international contagion of macroeconomic instability from one country to another. Exchange Rate Regimes and Macroeconomic Stability offers perspectives on these issues from the viewpoints of two Nobel Laureates, an IMF economist, and Asian economists. This book contributes new ideas to the ongoing debate on the role of domestic monetary authorities and international institutions in reducing the likelihood of international financial crises, as well as the problems associated with various exchange rate regimes from the standpoint of macroeconomic stability. Overall, the chapters contained in this volume offer interesting perspectives, which have been stimulated by the recent events in the foreign exchange market. They provide a useful reference for anyone interested in the development of exchange rate regimes, and represent considerable reflection by economists half a century after Bretton Woods.
