Sharing a polluted river network through environmental taxes

Resumo

Dong et al. (2007) consider a river network divided into n segments. In each segment there is exactly one agent, who throw some kind of residue into the water. An environmental authority must share the total cost of cleaning the river network among all the agents. In this paper we propose several rules to distribute the total cleaning- cost among the agents. Moreover, we provide axiomatic characteriza- tions for them using properties based in water taxes. Both, the rules and the characterizations are generalizations of the ones given in Gómez-Rúa (2008)
