Abstract

: L’analyse d’impact de la libéralisation du commerce des produits agricoles et produits alimentaires et les politiques de réduction de la pauvreté sont au centre des débats nationaux au Sénégal et des négociations commerciales avec le reste de monde. Même si certaines réformes sont globalement bénéfiques à l’économie sénégalaise, il est possible que certains n’y trouvent pas leur compte. Dans ce contexte, il est important de bien comprendre qui sont les gagnants et les perdant de ces réformes envisagées afin de mieux expliquer les réformes et/ou compenser les perdant des réformes. Il est aussi possible que certaines politiques ciblées n’atteignent pas leurs objectifs. Nous proposons d’analyser quelques réformes d’actualités au Sénégal et leur impact en terme de variation de pauvreté et de distribution de revenus sur certains groupes de la population. Nous utilisons un modèle d’équilibre général calculable multi-ménages intégrés permettant d’endogénéiser la variance de revenus intra-groupe. Nous appliquons systématiquement deux méthodes d’estimation de distribution des revenus (paramétrique et non-paramétrique) afin de voir s’il y a des différences qualitatives et quantitatives des effets. Concernant l’approche paramétrique, nous retenons les distributions les plus appropriées pour chacun des groupes selon des tests économétriques effectués. Nous avons testé six distributions différentes et retenu celle reflétant le mieux la vraie distribution. Les résultats montrent que certaines politiques peuvent avoir des effets différents de ceux initialement visés. Il ressort également que l’approche paramétrique est plus sensible que l’approche non paramétrique.
