A Comparison of Contingent Preference Models
比较了条件评级、条件排序和两种条件配对比较方法作为公投式条件估值法的替代方案的信息效率，利用猎人对假设狩猎旅行的评级数据估计间接效用模型并推导支付意愿，证实条件评级法相对更有效。
Abstract I compare the informational efficiencies of contingent rating, contingent ranking, and two contingent paired‐comparison methods as alternatives to the referendum contingent valuation method. The contingent rating method is hypothesized to be most efficient because ratings convey information on preference intensities and can uniquely represent respondent indifference or ambivalence. Survey data on hunters' ratings of alternative hypothetical hunting trips are used to estimate four alternative indirect utility models from which marginal willingness‐to‐pay measures for individual trip attributes are derived. Model comparison, WTP estimates, and their confidence intervals confirm the relative efficiency of the contingent rating approach.
