Abstract

Nous étudions un duopole sur un marché où les produits sont différenciés horizontalement. Les firmes se font concurrence en catalogue dans le sens où elles choisissent simultanément un produit et un prix. Nous montrons alors qu'il n'existe pas d'équilibre de Nash en stratégie pure en simultané mais qu'une structure leader-follower permet de restaurer l'existence d'un équilibre. Dans cet équilibre sous jeux parfait, le leader choisit un produit plus spécifique et à un prix plus faible que le suiveur. Le leader fait donc un profit inférieur à celui du suiveur. Cela induit une tension entre la tentation de l'attrition, qui conduit à une situation instable, et la volonté de se garantir un profit strictement positif.
