We investigate consumers’ preferences towards local and organic food via a framed field experiment involving revealed multiple discrete–continuous choices. Participants were endowed with a cash amount as a budget to purchase any desired quantity of different products. We modelled choices via the multiple discrete–continuous nested extreme value model. Central to our investigation is the test of the hypothesis of the constant effect of attitudes across consumption doses, which is normally an assumption invoked a priori and without testing in discrete choice analyses. Our results support the hypothesis and reveal a strong preference towards organic and local products, associated with both the highest baseline utility and the lowest satiation effect.

本地和有机产品是否不那么令人满意？来自现场实验的一些证据

我们通过涉及多个离散-连续选择的框架式现场实验调查消费者对本地和有机食品的偏好。参与者被赋予现金金额作为购买任何所需数量的不同产品的预算。我们通过多个离散连续嵌套极值模型对选择进行建模。我们研究的核心是检验态度对消费剂量的恒定影响的假设，这通常是一个先验假设，没有在离散选择分析中进行检验。我们的结果支持了这一假设，并揭示了对有机和本地产品的强烈偏好，这与最高的基线效用和最低的饱腹感有关。
