Air pollution requires multipollutant analysis: the case of Santiago, Chile

In many ways, air pollution control presents itself as a textbook example for cost-benefit analysis. Air quality certainly is a public good in the sense that it can be enjoyed by one without excluding the other, so there certainly is a role for government in weighing trade-offs and guiding resource use. This study breaks new ground in presenting a decision-oriented, multipollutant cost-benefit analysis while highlighting the simplifications and assumptions required to attain this goal.
