Abstract

Les comptes nationaux ont été, pendant longtemps, l’une des préoccupations majeures dans la production de statistiques économiques au sein de l’administration publique sénégalaise. Les travaux de la comptabilité nationale s’intéressent beaucoup à la production statistique des comptes et d’autres tableaux synthétiques comme le Tableau Economique d’Ensemble et le Tableau des Entrées Intermédiaires (TEI). Le TEI, conçu grâce à la détermination des coefficients techniques, met en exergue les interrelations entre les différentes branches d’activités. La présente étude s’inspire des travaux de Leontief [1927] sur les modèles input-output et propose une démarche synthétique permettant de calculer des coefficients techniques robustes, ainsi que leurs intervalles de confiance. Les données utilisées proviennent d’une compilation des Tableaux Entrées Sorties (TES) de 1980 à 2004. Pour assurer la robustesse des résultats, un estimateur hybride, combinaison optimale de la moyenne et de la médiane a été privilégié. Les résultats obtenus mettent en évidence, une bonne adéquation entre les intervalles estimés et les données réelles observées. Les simulations faites dans le cas d’une flambée du prix du baril en 2005, répliquent assez bien la réalité observée dans la structure économique au Sénégal.
