Valuing Water Quality as a Function of Water Quality Measures
利用湖泊水质属性、家庭特征和出行信息，构建混合Logit模型分析休闲湖泊使用，发现个体对生物学家用于判定湖泊受损状态的全部水质指标都有反应，并报告了改善这些物理指标的支付意愿。
Abstract Employing a unique and rich data set of water quality attributes in conjunction with detailed household characteristics and trip information, we develop a mixed logit model of recreational lake usage and undertake thorough model specification and fitting procedures to identify the best set of explanatory variables, and their functional form for the estimated model. Our empirical analysis shows that individuals are responsive to the full set of water quality measures used by biologists to identify the impaired status of lakes. Thus, changes in these quality measures are not simply a scientific exercise, but they also translate into changes in the recreational usage patterns and well‐being of individual households. Willingness‐to‐pay (WTP) estimates are reported based on improvements in these physical measures.
