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

A brief summary of the sensitivity analysis is that the low case is sufficiently low to make the control strategy marginally attractive, even though two subcomponents will remain very unattractive. In sum, however, the control strategy appears to be an attractive proposal, yielding more than it costs in mere health benefits. Importantly, it would have been conceptually more correct to base the valuation of these health effects on willingness-to-pay estimates. Likely, this would have given higher health benefits, and the need to go in this direction is therefore stronger as one turns toward additional, more expensive options providing pollution reductions (for a review of such estimates, see Viscusi).
