Originally published in 1986. This helpful text sets out what appears to make exchange rates change and shows how these various factors contribute to an explanation of the past. It considers the problems of providing satisfactory forecasts of the exchange rate while presenting the methods used, outlining their drawbacks and speculating on future ways forward. Laid out to move from empirical issues to theory and on to policy, this book is easily of use to those interested in macroeconomics, applied economics and international economics as well as economic history.
