The period since the Second World war has been an eventful and often disturbing one in the international monetary field. Economic theories have been propounded and modified both to explain these events and to influence future choices made by economic actors. This history of international monetary relations shows both how theoretical development affected private developments, and how the theories themselves have been judged - and often discarded - on the basis of their perceived accordance with actuality. Exchange rate movements in particular are examined in the light of the absence of any generally accepted fundamental model, and the author deploys here his own theory based on the idea of bounded rationality. Finally, he looks ahead to future possibilities for the international monetary system.
