Abstract

Dans ce travail nous explorons la contribution en terme d’introduire de l’hétérogénéité inter ménages d’intégrer une fonction de demande flexible dans un cadre d’analyse de modélisation en équilibre général calculable de type micro-simulation multi-ménages intégré (EGC-MMI). Afin de pouvoir résoudre le modèle nous proposer d’utiliser des éléments de l’approche EGC-TD/BU proposé par Savard (2003). Nous retenons de travailler avec le système de demande presque parfait (AIDS) qui présente des propriétés intéressantes en termes de spécificités des comportements pour chacun des ménages. Toutefois, cette fonction a aussi des propriétés (non quasi-concavité globale) peut rendre son utilisation dans le contexte de modélisation en EGC difficile. Afin de montrer la contribution d’introduire le système de demande AIDS, nous comparons les résultats avec un modèle à agent représentatif ainsi qu’avec un modèle micro-simulation EGC-TD/BU utilisant un système de demande AIDS. Les résultats montre que la mesure de changement de bien-être qui correspond au système de demande AIDS est très sensible aux changements de revenu et de prix généré par le modèle. Par conséquent, les variations des indices de pauvreté et d’inégalité sont beaucoup plus fortes que celle observé dans un modèle à agent représentatif et avec un modèle utilisant le système de demande linéaire.
