A 1983 study investigates the stability of collusive price leadership and shows that a dominant cartel is always stable with a finite number of firms.
Abstract
The gains from cartel formation and the stability of a dominant cartel are investigated for the price-leadership model. We show that there is a general interest in the establishment of a cartel with the competitive fringe reaping a disproportionate share of the benefits. In contrast to results involving a continuum of firms, with a finite number of firms (each with the same cost curve) there is always a stable dominant cartel. A propos de la stabilite d'une structure de marche caracterisee par la collusion de firmes dominantes pour etablir un leadership de prix. Le memoire etudie les gains derives de la formation d'un cartel et la stabilite d'un cartel dominant dans le cadre d'un modele de leadership de prix de la firme dominante. On montre qu'il y a un int6ret general a creer un cartel meme si les firmes satellites A la peripherie du cartel ramassent une part plus que proportionnelle des benefices. Contrairement a ce que l'on observe quand on est en presence d'un continuum de firmes, quand leur nombre est fini chacune avec la meme courbe de couts il y a toujours un cartel dominant stable.
