This paper uses a randomized survey instrument to study the impact of African Swine Fever (ASF) information on Chinese consumers’ preference for pork attributes and purchases during the recent peak of the ASF pandemic in 2019. We study consumers’ preference for pork attributes including brand, meat texture and taste, quality safety assurance, and traceability under different information treatments. Results show that the willingness to pay (WTP) for quality safety assurance is the highest, followed by brands and traceability systems, and the WTP is lowest for good taste. We show that providing detailed ASF information substantially changes consumer preference by altering the relative importance of pork attributes and price sensitivity, which enables consumers to focus more on safety-related attributes while paying less attention to price and taste attributes. Furthermore, we find that a higher belief in the future of ASF occurrence reduces the frequency of purchases marginally but does not significantly influence for amount per purchase and the total purchase amount. 相似文献

The aim of our research is to examine Swedish consumers' perception and preferences of domestic vegetables compared to on the one hand imported and on the other hand organically grown vegetables. The paper draws from two consumer studies. The first study is a text analysis of consumers' associations to the four concepts Swedish, imported, organic and conventional vegetables as well as a conjoint analysis of the relative importance of the same four characteristics in the case of carrots. The second study is a taste experiment on tomatoes from the same Swedish grower labelled in three different ways, as Swedish, Dutch or organic. The conjoint analysis indicates that Swedish origin is considered more important than organic production methods. The text analysis shows that Swedish is associated with positive values, for instance, high quality, while imports have a more negative image. Organic is associated with characteristics such as being non-toxic, good quality and expensive while conventional is associated with poison, being good enough and traditional. The preference for Swedish vegetables is supported by the taste study. Tomatoes that were labelled as Swedish or organic were perceived as tastier than tomatoes labelled as Dutch. Thus, the experience of taste seems to be affected by the labelling. The conclusion is that to many Swedish consumers “Swedish is good enough” as a quality criterion. However, the research situation differs from a real shopping environment, where consumers make choices between bundles of different attributes, not only provenance and production method. Moreover, in a real shopping situation supermarkets promote their own private brands, regardless of origin, thus make origin less accentuated. 相似文献

This article is, to the best of our knowledge, the first investigation of Tunisian olive oil consumer behavior by the use of the conjoint analysis technique. The conjoint experiment was based on carefully selected olive oil attributes: type, taste, color, packaging, region of origin, and price. The results have important implications to improve the marketing of olive oil in the local market by focusing on key preferred attributes. Consumers were found to prefer more extra-virgin, followed by virgin olive oil, to pomace oil. They also showed higher preference for green colored olive oil with strong flavored taste. Contrary to a common belief in Tunisia, the region of origin attribute did not show significant effect on consumers’ purchasing decisions. The results show also that Tunisian olive oil consumers are price sensitive and therefore any price strategy to introduce bottled products should take into account consumers’ preferences for bulk purchase. 相似文献
