Abstract

CUB models have been developed in order to take into account the latent process of evaluating an object (product, service, etc.). Feeling and uncertainty are supposed to be involved in the choice process. Several model extensions have been developed since their introduction and application studies have proven to be a very useful approach. In a survey on food packaging, respondents had to evaluate their grade of attention paid to some grocery product characteristics and their satisfaction towards packaging attributes. Thanks to CUB models interesting results can be drawn. For instance respondents are very interested in "provenance" and "seasonality" of products with some group differences and they are satisfied towards food preservation again with interesting differences among groups.
