The analysis focuses on the cost-effectiveness of BOD5 control methods in the Bío Bío river basin, comparing standard control policies with a market system. While theoretical models suggest the market system is efficient, it falters under strict compliance with environmental targets, leading to a reduction in permits. This study highlights that at certain environmental demand levels, transferable discharge permits become inefficient due to factors such as water system restrictions, high marginal abatement costs from polluting sources, and the limited capacity of receiving waters.

Il documento analizza i costi del controllo del BOD5 nel bacino del fiume Bío Bío, confrontando il controllo standard con un sistema di mercato. Sebbene il sistema di mercato risulti vantaggioso in teoria, perde efficienza quando si impongono obiettivi ambientali rigidi, a causa di restrizioni e costi marginali elevati.

Cet article analyse les coûts du contrôle de la DBO5 dans le bassin du Bío Bío, Chili, en comparant les politiques standard à un système de marché. Bien que ce dernier soit théoriquement rentable, son efficacité diminue lorsque des objectifs environnementaux stricts sont imposés, notamment en raison de contraintes locales et de la capacité d'assimilation des eaux.
