Stated Preference Approaches for Measuring Passive Use Values: Choice Experiments and Contingent Valuation
比较了选择实验与条件价值评估两种方法在测量环境被动使用价值上的表现，发现选择实验在估计偏好方面具有显著优势。
Abstract The measurement of passive use values has become an important issue in environmental economics. In this paper we examine an extension or variant of contingent valuation, the choice experiment, which employs a series of questions with more than two alternatives that are designed to elicit responses that allow the estimation of preferences over attributes of an environmental state. We also combine the information from choice experiments and contingent valuation to test for differences in preferences and error variances arising from the two methods. Our results show that choice experiments have considerable merit in measuring passive use values.
