Contenir le marché : la transition de la criée à la cotation électronique à la Bourse de Paris

Open outcry was fully replaced at the Paris Bourse by an automated trade execution system (CAC) in the late 1980s. In this article, we focus on the circumstances that made this transition possible. We analyze the diverse compromises (both social and technical) that the officials and engineers in charge of the innovation process constructed in order to stabilize the new market device. They had to carefully inscribe into the new system the interests of the actors at stake: bankers and stockbrokers. This case study contributes to economic sociology by drawing a relation between a technical device and the interests set around the “modernization” of a market.     

Les régimes de production des connaissances de la sélection animale. Ontologies,mesures, formes de régulation

This paper analyses the co-production of knowledge and socio-economic order in animal breeding. Is it possible to historicise analyses of the actor-network theory (ANT) and to show forms of pairing between knowledge production and sociopolitical order typical of a given historical period? Symmetrically, in an approach based on regimes of knowledge, how do we account for the differences that remain over a given period? Drawing on the differences in the exploitation of animal genetics in three production sectors (beef, pork, chicken), this paper analyses the diversity of the composition of the socio-(bio)technical methods of animal selection and the mechanisms for stabilising these methods. It also explains the relations with factors whose forms of existence do not depend only on local arrangements. In this way, one can move from local heterogeneous agencements to regimes of knowledge.
