Modèles et mécanismes en économie: essai de clarification de leurs relations


  • SALMON, Pierre

    () (LATEC - Université de Bourgogne)


L'article est un essai de clarification des relations entre modèles et mécanismes économiques. Ces derniers se réfèrent à des processus et des interactions de nature causale. Interviennent-ils dans les modèles? Il faut distinguer les modèles comme entités construites de nature non-linguistique et les modèles au sens habituel de systèmes formalisés de définitions et de relations mathématiques. Les seconds sont interprétés comme visant à caractériser ou à décrire partiellement les premiers. En conséquence, l'absence dans beaucoup de modèles formalisés de toute référence explicite à des mécanismes en termes de processus ne signifie pas qu'ils ne jouent pas un rôle essentiel dans les modèles non-linguistiques que ces modèles formels décrivent de façon incomplète. / The article is an attempt to clarify the relationship between economic models and mechanisms. The latter refer to causal processes and interactions. What role do they play in models? One must distinguish between models as non-linguistic constructs and models in the more usual sense of formal systems of definitions and mathematical relations. Models in the second sense are interpreted as purporting to characterise or describe in part models in the first sense. Thus the fact that there is no explicit reference to process-based mechanisms in many formal models does not mean that these mechanisms do not play an essential role in the non-linguistic models that these formal models describe in an incomplete way.
