The Influences of Portion Size,Context and Package Characteristics on Snack Food Consumption: Evidence from a U.S. Rolling Cross-Sectional Survey

Using a rolling cross-sectional sample of over 40,000 U.S. snack food consumers during 2004–2010, we build a three-dimensional model to study how portion sizes, consumption context, and package characteristics jointly affect the amount of food consumed. As with prior research, we find that consumption does increase with larger portions. However, this effect diminishes significantly when accounting for the consumption context and packaging characteristics as consumption drivers. Most important is how the snack is presented to consumers at the point of consumption (type, size, and quantity of packages). We also find that snacking on impulse, alone, with a beverage, or while watching television increases the amount consumed, whereas socializing or snacking at home decrease consumption. We test our model over seven snack types (potato chips, crackers, cheese puffs, nuts and seeds, tortilla chips, pretzels, popcorn), and find that our results hold even for products with different cross-category granularity, palatability, and satiety.

Contrasting user generated videos versus brand generated videos in ecommerce

This empirical research (n = 177) compared the impact of user generated videos and brand generated videos on online shopper perceptions, attitudes and purchase intentions. The study was guided by the technology acceptance model. Source of videos was a between-subjects factor. The findings indicated that online shoppers did not differentiate between the two video sources when evaluating the perceived usefulness of the videos. Conversely, user generated videos had a significantly greater impact on attitude toward the ad and attitude toward the brand than brand generated videos. Further, there was no significant main effect of video source on shopper purchase intentions. Theoretical and practical implications are discussed.     

How green is your packaging—A comparative international study of cues consumers use to recognize environmentally friendly packaging

Consumers have grown increasingly aware of the impact of packaging on the environment. Therefore, interest has grown in more environmentally friendly packaging, but we wondered how consumers recognize ‘green’ as distinct from ‘grey’ when evaluating packaging. We asked over 3,000 respondents from Germany, France and the United States how they recognize environmentally friendly packaging. To solicit responses that we may not have anticipated, we used an open‐ended format, which we then followed with a closed‐ended format so that we could compare the two sets of responses. Not surprisingly, in both sets of responses, we found labelling to be the attribute consumers rely upon most, as well as evidence of misleading labels. We also found consumers in Germany and the United States relied on information on the packaging and named searching for information as one of their preferred ways to decide whether packaging is environmentally friendly. French consumers seemed less trusting of published information and more trusting of the look and feel, especially the material, of the package. Our results point to the importance of cultural influences in the acquisition of perceptual cues by the consumer.

社交网站中网络口碑对消费者团购意愿的影响——考虑品牌信任的中介作用

分析了社交网站中的网络口碑对消费者团购意愿的影响,并探讨了品牌信任对上述影响的中介作用。基于对304位有网络团购经验的高校学生的深度访谈和问卷调查,运用因子分析、相关分析以及结构方程模型等方法,对相关假设进行了实证分析。结果表明:社交网站网络口碑的数量、质量和时效性与消费者团购意愿之间存在显著、正向且直接的影响关系,品牌信任在二者之间发挥部分中介效应。     

Role of gender differences on individuals’ responses to electronic word-of-mouth in social interactions

Considering the significant effects of electronic Word-of-Mouth (eWOM), this research explores how individuals respond to eWOM and whether gender differences exist in their perceptions. To do so, by employing the perspective of social interactions, we examine the proposed relationships are different between genders. We collected data using a survey and tested the hypotheses via path analysis. The results indicate that, gender differences were found specific to search effort, product involvement, and information credibility. Women with strong online ties had a tendency to be more involved in the product information and to find the information more credible. In addition, when women had an increased search effort, they were more likely to have intention spread eWOM. This research provides insights to further research related to gender differences in eWOM by discussing implications for research and practice.
