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.
