与采用直接提问方法的传统陈述偏好估值技术相反，推断估值方法利用间接提问，询问受访者对他人对商品或服务价值的看法。在这项研究中，使用选择实验，我们比较了通过两个估值技术的环境特征的布尔伦景观在西部爱尔兰的结果。与以往的研究一致，使用传统方法的陈述价值被发现显着高于通过推断估值方法获得的。特别是，这项研究突出了两个景观属性（岩石石灰石路面和富含维生素的草地）从两个提问格式之间观察到的相对偏好的差异。虽然受访者对这两种栖息地漠不关心，但他们认为“普通人”更关心石灰岩路面的保护。我们认为这种偏好的差异是由于受访者认为的额外的规范性动机，以保护丰富的草原。
Contrary to conventional stated preference valuation techniques that employ a direct questioning approach, the inferred valuation method utilises indirect questioning where respondents are asked for their belief regarding others’ values for a good or service. In this study, using choice experiments, we compare the results obtained through the two valuation techniques for environmental features of the Burren landscape in western Ireland. Consistent with previous studies, stated values using the conventional approach are found to be significantly higher than those obtained through the inferred valuation approach. In particular, this study highlights the dissimilarities in relative preferences observed between the two landscape attributes (rocky limestone pavements and orchid-rich grasslands) from the two questioning formats. While respondents were indifferent between the two habitats, they believed the ‘average other’ to be significantly more concerned about the conservation of the rocky limestone pavements. We attribute this divergence in preferences to be a consequence of additional normative motives perceived by respondents with regard to the conservation of orchid-rich grasslands.
