Albert Aftalion introduced Austrian marginalism into France and used it not only to tackle the issue of imputation (1911) but also to build his own theory of business cycles (1913) and of money (1927). Aftalion did not, however, receive the recognition he deserved for his contributions. The reasons are twofold. First, his use of modern analytical tools did not fit well with the dominant bias for the historicist approach that prevailed in France at the time, especially before 1914. Second, the fact that his contributions were available only in French did not help in spreading widely his ideas outside his native country.
