Abstract

In responding to G. Delplace, J. Sapir specifies that he defends a methodological « holist-subjectivist » position, in which the individual behaviours are influenced by collective contexts, constituting an alternative to the Theory of General Balance. In responding to A. Orléan, he confirms his opposition to a vision that rends currency the economical institution or the central social relation. The monetary crisis expressed by the return of barter et the fragmentation off the subsisting monetary space will find no other issue than by the ex-post emergence of a new form, and not by a preexisting, ex-ante totality
