Estimating the Demand for Air Quality in Four U.S. Cities
利用1974-1991年美国住房调查等数据，通过特征价格模型估算空气质量的边际价格，并估计四个都市区的空气质量需求方程，发现其中两个城市的自价格系数显著为负、收入系数显著为正。
An analysis of the demand for air quality in four MSAs in the United States is presented using the American Housing Survey data from 1974-1991, the Decennial U.S. Censuses, and the EPA Aerometric Information Retrieval System. The marginal prices of air quality are obtained from parameter estimates for the pollution variables in a hedonic house price model, and the marginal willingness to pay (inverse demand) equations for air quality are estimated using these prices. In two of the four (inverse) demand for air quality equations, the own-good coefficient is negative and significant, while the income coefficient is positive and significant.
