Abstract

Cet article compare, dans un oligopole polluant, une taxe par unité de pollution et une forme de régulation environnementale dite approche volontaire (AV). En réduisant la quantité produite par les firmes, la taxe amplifie la distorsion due à la concurrence imparfaite et est sous-optimale. L'AV est ici un contrat sur l'effort de traitement de la pollution que les firmes peuvent accepter ou non, sachant que, si elles le refusent, elles payent la taxe. Cette forme d'AV limite l'impact de la réduction de la pollution sur la quantité produite en incitant uniquement au traitement de la pollution en fin de processus de production. Étant donné les hypothèses posées, on obtient une condition nécessaire et suffisante sur les paramètres pour laquelle ce type d'AV est plus efficace que la taxe. Cette condition est vérifiée pour réguler une industrie concentrée et une forme de pollution relativement peu nuisible et facile à traiter.
