Estimating the Demand for Air Quality: New Evidence Based on the Chicago Housing Market
利用大型家庭层面数据和两阶段特征价格法，估计家庭为减少空气污染（PM-10和SO2）的支付意愿，发现PM-10的边际支付意愿与以往研究相当，且非边际变化的货币收益高于SO2。
This paper combines a new, large household-level data set with the two-stage hedonic- estimation technique to derive new estimates of willingness to pay (WTP) for reduced air pollution. The WTP estimates are found robust against functional-form specification. Marginal WTP estimates for a reduction in particulate matter (PM-10) are found to be quite comparable with some previous estimates. Benefits of nonmarginal changes exhibit consistently higher monetary returns in the case of PM-10 than in the case of SO2, signifying that households dislike particulate pollution more than they do sulfur.
