Abstract

La nouvelle orientation de la politique économique au Sénégal vise à accroître les revenus des pauvres et à attaquer la pauvreté là où elle est principalement localisée. La stratégie de réduction de la pauvreté va être mise en oeuvre dans un contexte de libéralisation des échanges commerciaux internationaux notamment dans le secteur agricole. Dans ce contexte, nous avons développé un modèle d'équilibre général calculable micro-simulé multi-ménages du type Decaluwé et al. (1999) permettant d'évaluer l'impact que pourront avoir ces politiques agricoles à l'échelle des ménages et de faire le lien entre ces réformes économiques, la pauvreté et la distribution de revenu. Ce modèle offre beaucoup de flexibilité en permettant notamment de modifier la distribution des groupes cibles qui n'ont pas à être revenus avant l'exercice de simulation afin d'effectuer l'analyse de pauvreté et d'inégalité ex post à l'exercice de modélisation. Dans ce travail, nous avons également comparé les effets en terme d'analyse de pauvreté et d'inégalité entre une distribution paramétrique (Dagum, 3 paramètres) et une distribution non-paramétrique et montré que ce choix engendrait des différences significatives quant aux effets sur la pauvreté. Contrairement aux applications faite par Decaluwé et al. (1999) et Cockburn (2002) au Népal, les impacts sur la pauvreté sont assez importants, ce qui montre que cette approche offre un outil riche permettant d'évaluer l'impact de politiques économiques ou chocs externes sur la pauvreté et la distribution de revenu.
