Abstract EN:
Economic activity is a field in which many different types of behavior may be observed concerning inventories. Firms have a multiplicity of reasons for holding inventories (transaction, precaution, speculation, production smoothing, buffer stocks). These reasons lead firms to try to maintain a stable relationship between inventories and sales. However, this classical view is partially questioned by production pull systems (production without inventories). As for households, in addition to classical reasons, they gave more spychological motives for holding inventories (accumulation, safety). Through the specification of macroeconomic models (accelerator, production smoothing), the study of individual inventory behavior leads us to determine the impact of changes in inventories on economic equilibrium
Abstract FR:
L'activite economique est un domaine ou l'on observe de nombreux comportements de stockage. Les entreprises ont de multiples raisons de detenir des stocks ( transaction, precaution, speculation, lissage de la production, stock-tampon) ces raisons conduisent les entreprises a tenter de maintenir une relation stable entre stocks et ventes. Cette conception classique est cependant partiellement remise en cause par les systemes de production a flux tires (production sans stocks). Les menages, quant a eux, ont en plus des raisons classiques, des motifs de detention plus psychologiques (accumulation, securite). L'etude des comportements individuels de stockage conduit, a travers la specification des modeles macroeconomiques (accelerateur, lissage de la production), a determiner l'influence des variations de stocks sur l'equilibre economique.
