Abstract

Cette analyse emploie le modèle des corrélations conditionnelles dynamiques développées récemment par Engle (2002) pour déterminer le caractère synchrone ou asynchrone des mouvements des taux de croissance de la valeur ajoutée des différents secteurs économiques au Luxembourg. Le recours à cette méthodologie, initialement développée pour l?analyse des séries financières, s?explique principalement par la non-constance de la volatilité des séries trimestrielles des composantes du PIB luxembourgeois. Cette caractéristique de la volatilité demeure naturelle pour une petite économie très ouverte, sujette par ailleurs, à une multiplicité de chocs exogènes dont les effets se traduiraient par une plus grande volatilité des agrégats économiques. Nous adoptons, par ailleurs, le test de causalité des moyennes et des variances construit par Cheung et Ng (1996) pour confirmer ou infirmer le rôle attribué par certains au secteur financier en tant que locomotive de l?économie luxembourgeoise.
