Abstract

On modifie le modèle leader-imitateur de Barro et Sala-i-Martin [1997] en supposant qu?au fur et à mesure que le retard technologique s?accroît, la productivité de la R&D (i) d?abord augmente puis diminue dans la région en retard, et (ii) elle diminue dans la région leader pour des retards extrêmes. Le modèle montre qu?il peut y avoir deux équilibres stationnaires stables. L?économie peut converger vers un équilibre Pareto-inférieur où le niveau d?inégalité inter-régional est accru et le taux de croissance commun réduit. Le libre mouvement des facteurs accentue le problème.
