Exchange rate economics is an important field of investigation for academics, professionals and policy-makers.

Eighteen well-known policymakers and economists discuss the rising use of currency substitution in Latin America. They examine the effects of currency boards on substitute currencies and on national stabilization programs. Latin American countries including Argentina, Bolivia, Peru, and Uruguay increasingly use dollars as a substitute for domestic currency. The experts debate whether the region should encourage or resist this trend. Topics include the effects of substitution on inflation, liquidity, and exchange rates. The discussions on Argentina, Peru, and Brazil focus on the ways in which currency boards have affected stabilization in these countries. They consider whether such boards can strengthen fiscal discipline and speed economic adjustment. A currency board issues money that is converted into a foreign reserve currency at a fixed exchange rate. This independent institution takes over the central bank's role as the sole issuer of base money. It also manages the exchange rate to keep the currency stable and convertible.

In a single volume, this book treats the theoretical, empirical, and case studies approaches to the implementation of monetary reforms and discusses specific countries' experiences with these approaches. The analyses are not restricted to central bank or exchange rate reforms, but consider all the principal tools of monetary reforms in this volume. The first section surveys and examines the types of monetary reforms. The second and third sections examine the pros and cons of exchange rate management and central bank independence. The final section of the book presents case studies on monetary and central bank experiences in Germany, the United States, Canada and Hungary.

The book sets out to show the current state of macroeconomics, from three main perspectives: methodology, theory and economic policy. It is built on extensive conversation with some of the world's leading macroeconomists. These are based on wide questionnaires, covering jointly almost all the topics of macroeconomic theory, as well as questions of methodology, real economy, and even academic systems and future lines of research. Some of the questions have been put to all the respondents or many of them, with the aim of bringing out their different positions. References about authors and themes are also provided.
