摘要

本文介绍了一个基于篮子和支出的选择实验设计,以引出消费者对多种产品的偏好。这个设计是用来模拟一个更真实的购物场景,让消费者同时在许多不同的产品中进行选择。这种方法允许参与者选择多个项目,在这个例子中是蔬菜,以及相关的数量/支出来放置在一篮子商品中。我们将实验设计应用于蔬菜选择实验。这是与感官实验一起完成的,为实验和计量经济模型提供上下文成分。这种类型的实验适合使用多重离散连续极值(MDCEV)类模型。更具体地说,我们使用了Palma和Hess(2020)提出的MDCEV模型的扩展版本,该模型放宽了对预算的需求,同时也考虑了产品之间的替代和互补性。我们发现,所提出的设计和计量经济学方法的类别提供了一种灵活的方法来分析消费者的选择,当欲望是引出对一篮子商品的偏好,而不是简单的离散选择或属性。

Matching reality: A basket and expenditure based choice experiment with sensory preferences

This article introduces a basket and expenditure based choice experiment design to elicit consumer preferences for multiple products. This design is utilized to imitate a more realistic shopping scenario for consumers when choosing among many different products simultaneously. This approach allows participants to choose both multiple items, in this case vegetables, and related quantities/expenditures to place in a basket of goods. We provide an application of the experimental design to a vegetable choice experiment. This is done in conjunction with a sensory experiment to provide a contextual component to the experiment and econometric model. This type of experiment lends itself to the use of the Multiple Discrete-Continuous Extreme Value (MDCEV) class of models. More specifically, we use the extended version of the MDCEV model proposed by Palma and Hess (2020) that relaxes the need for a budget while also accounting for substitution and complementarity among products. We find that the proposed design and class of econometric methods present a flexible way to analyze consumer choice when the desire is to elicit preferences for a basket of goods rather than simple discrete alternatives or attributes.
