Trade Liberalizaiton and Oligopolistic Industries: a Welfare Appraisal

  • Tito Cordella

Cet article essaie d'évaluer, à travers un exemple, les effets en termes de bien-être de la libéralisation des échanges intra-industriels entre deux pays. Si il est vrai que la libéralisation des échanges accroît le bien être « mondial », sous certaines conditions un des deux pays peut avoir intérêt à conserver une situation d'autarcie. Les paramètres qui nous permettrons de juger du caractère bénéfique de l'ouverture du marché domestique à la compétition étrangère sont les tailles relatives des marchés interne et étranger, ainsi que la taille de l'industrie considérée. La prescription de libre-échange sur base unilatérale est valide seulement si l'industrie étrangère est très compétitive et, seulement dans ce cas, les gains des consommateurs compensent les pertes des producteurs. Finalement nous montrons que, si les politiques commerciales sont décidées d'une façon non-cooperative, le libre-échange ne peut jamais être un équilibre de Nash.
