Researchers have investigated the role of sensory attributes and organic labels on consumers’ preferences and perceptions of food, but few has examined whether sensory attributes are relevant for consumers who prefer organic food and the extent to which sensory attributes influence consumer's marginal willingness to pay for organic food. The objective of this study is to determine how sensory attributes and organic label work together to influence consumer's stated preference and marginal willingness to pay for orange juice. To achieve this, we conducted a blind sensory evaluation of two orange juices followed by a discrete choice experiment to determine the extent to which consumer's stated preference for orange juice labelled as organic is affected by sensory experience preceding the choice experiment. Random parameter logit models and latent class conditional logit models are used to explain stated preference. Results indicate that the effect of sensory attributes on consumer's marginal willingness to pay differed by organic juice and conventional juice. 相似文献

This study examined the impacts of retail promotions on the demand for five brands of orange juices for a retail chain (referred to as Retailer X) and its competitors using the Rotterdam model. Results show that the combination of feature ads and displays had the largest impacts on retail revenue among the four promotional tactics considered, whereas temporary price reductions had no advertising impacts on retail revenue. Results also show that when Retailer X promotes an orange juice (OJ) brand using any of the tactics, a larger portion of the increased demand for the promoted brand comes from reduced demand for other brands of OJ in the same store or chain.A smaller portion comes from the decreased demand in Retailer X's competing stores in the same trading area. 相似文献
