Exchange rate economics is always and everywhere controversial
School of Business and Law
This article reviews the major developments in the recent literature on exchange rate economics. It is argued that the link between the exchange rate and economic fundamentals is breaking new ground. Evidence indicates that alternative analytical frameworks (such as the new open-economy macroeconomics) and exchange rate arrangements (such as the euro) have their theoretical and analytical elegance, but are proving empirically very difficult to implement. The role of methodological advances and alternative fundamental instruments (such as world commodity prices) is also highlighted.
