The study proposes a discrete-choice model for environmental policy/program valuation, to be used in cases when several policies are valued sequentially. The stochastic specification of the model is consistent with the transitivity and continuity axioms of utility analysis. An empirical methodology for the model is suggested. An application of this model to WTP estimation for Little Tennessee River watershed ecosystem restoration is provided. Findings from the application agree with the hypothesized agent's behavior.

该研究提出了一种离散选择的环境政策/项目评估模型，用于对多个政策进行顺序评估的情况。模型的随机性说明与效用分析的传递性和连续性公理一致。提出了模型的实证方法。提出了该模型在小田纳西河流域生态系统恢复的WTP估算中的应用。应用程序的结果与假设代理的行为一致。
