摘要

这项工作提出了一个离散选择模型,该模型共同考虑了受访者在偏好和决策过程中的异质性,以及效用函数的非线性,从而考虑了选择实验中显著属性的潜在影响。我们在核能偏好的背景下提出了一个创新的应用,数据来自意大利进行的全国在线调查。结果表明,选择数据的大部分变化确实是由于决策过程中的异质性,其中显着启发式起着重要作用。此外,与标准模型相比,拟议的模型提供了更保守的货币估值,可能导致成本效益分析方面的重大差异。讨论了对选择建模从业者的影响,强调在建模选择数据时需要考虑显著性效应。

Testing for saliency-led choice behavior in discrete choice modeling: An application in the context of preferences towards nuclear energy in Italy

This work proposes a discrete choice model that jointly accounts for heterogeneity in preferences and in decision making procedures adopted by respondents, as well as for non-linearities in the utility function, allowing for the potential effect of salient attributes in choice experiments. We present an innovative application in the context of preferences towards nuclear energy, with data obtained from a nationwide online survey conducted in Italy. Results show that most of the variation in the choice data is indeed due to heterogeneity in the decision process, where the saliency heuristic plays an important role. Furthermore, the proposed model provides more conservative monetary valuations as opposed to standard models, potentially leading to substantial differences in cost-benefit analysis. Implications for choice modeling practitioners are discussed, emphasizing the need to account for saliency effects when modeling the choice data.
