A key distinction from the standard claims problem is that agents are ordered exogenously. For environmental rea- sons, the location of pollution along the river is an important concern in addition to fairness. We characterize the class of externality-adjusted proportional rules and show that they strike a balance between fairness and minimizing environmental damage in the river. We also propose two novel axioms that are motivated by the river pollution context and use them to characterize two priority rules. We illustrate the rules through a case study of the Tuojiang Basin in China.
