Fixed Vs Floating Exchange Rates

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.

We investigate the welfare properties of fixed and floating exchange rate regimes in a two-country, dynamic, infinite-horizon model with agents optimizing in an environment of uncertainty created by monetary shocks. The optimal exchange rate regime may depend on whether prices are set in the currency of producers or the currency of consumers. When prices are set in consumers' currency, the variance of home consumption is not influenced by foreign monetary variance under floating exchange rates, while there is transmission of foreign disturbances under floating rates if prices are set in producers' currencies, or under fixed exchange rates. An important feature of the model is the exchange rate regime affects not just the variance of consumption and output, but also their average levels. When prices are set in producer's currency, as in the traditional framework, we find that there is a trade-off between floating and fixed exchange rates. Exchange rate adjustment under floating rates allows for a lower variance of consumption, but exchange rate volatility itself leads to a lower average level of consumption. When prices are set in consumer's currency, floating exchange rates always dominate fixed exchange rates.

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.

This paper reviews recent experience with the choice of floating or fixed (“anchor”) exchange regimes in industrial and developing countries. It concludes that desirable differences between the two sets of regimes have narrowed, owing to the useful operational role of exchange rate margins and unavoidable medium-term rate adjustments in the context of fixed regimes. A survey of recent empirical cross-country literature also suggests little unambiguous association of the choice of exchange regime with macroeconomic performance, inflation in particular. Stability of the exchange rate has generally been a by-product of other policy choices. Even announcement effects of the regime on inflation-fighting credibility depend on the country-specific assignments of policy instruments to more than one institution--central bank, government, or regional and multilateral institutions.
