Food choice: student consumers' decision‐making process regarding food products with limited label information

Food label information theoretically facilitates consumer decision‐making and food choice, but the extent to which consumers actually use this information during decision‐making is a subject of considerable debate. Therefore, this study focused on the importance of label information in student consumers' decision‐making process when exposed to limited label information food in a cafeteria environment. Because of a paucity of research in this area, a qualitative research approach that was exploratory in nature was used, accompanied by semi‐structured interviewing and a vignette. Undergraduate students from the North‐West University, Potchefstroom Campus, in South Africa served as the target population. The findings suggest that internal and product‐related strategies are applied when food choices are made whereby the importance of label information only features in the latter strategy. Student consumers with a label interest were more inclined to use label information strategies in the absence of complete label information to base food choice on. Those with a lack of label interest made use of alternative strategies using product and personal‐related information, such as freshness and product knowledge to make decisions. The decision‐making process was more complex because of insufficient label information and product appearance, and thus previous experiences and habitual purchasing became more important to participants. Student consumers should be supported to make healthier food choices through food manufacturers supplying cafeteria products with more complete label information and by providing students with the knowledge to use label information correctly through educational programmes.

Utility of No Sweat Labels for Apparel Consumers: Profiling Label Users and Predicting Their Purchases

This study empirically analyzed whether consumers making apparel purchases would use a label guaranteeing certain working conditions were present during garment production. While a potential market segment for the No Sweat label was identified, evidence suggests that only a small percentage of consumers would be influenced by the label. This small market segment was profiled on its psychographic and demographic characteristics, and the extent to which the No Sweat label would influence future purchases was examined.     

Nutrition Labels: An Exploratory Study of Consumer Reasons For Nonuse

Studies of consumer usage of nutrition labels required by the Food and Drug Administration have found that usage levels are low. A mailback survey of food shoppers in Madison, Wisconsin was conducted to determine who uses nutrition labels as well as reasons for nonuse. Multiple regression analysis revealed that compared to users, nonusers did not rate themselves as highly on nutrition knowledge, were less likely to plan meals in advance, and were not as highly educated. When asked why they did not use labels, most nonusers said they did not need them, and a sizable group reported their shopping practices pre-empt label usage. Nonusers also felt that a sample label had too much information. When asked to perform computations from sample label information, nonusers were less successful than users. The implications of these findings for nutrition education efforts are discussed.     

Offering value and capturing surplus: A strategy for private label sales in a new customer loyalty building scenario

The competition between private label brand and national brands in the diaper category is investigated from the view of the private label brand manager. In this category, new customers routinely enter the category buying entry-level diaper sizes (for infants) and then progress to buy larger diaper sizes over time (as their child grows older). Thus, consumer comparisons between the private label brand and national brands are focused on single diaper sizes during any single purchase scenario. Because private label brands are known to suffer from low quality perceptions that often understate the true quality levels of private label brands, this paper advances a pricing strategy to optimize private label performance in the category. The private label brand should price significantly low for small diaper sizes (maintaining a sizeable price gap from national brand competitors). Then, in most cases, the private label brand should shrink the size of this price gap for large diaper size offerings. This strategy will successfully offer initial value to new customers, build private label brand quality perceptions and loyalty, and then capitalize on these gains through higher dollar sales in the late stages of the customer relationship. The price gap shrinking strategy is found to be generally effective, but high national brand competition and too high of an initial price gap diminish the effectiveness of the strategy.     

Coupons and private labels: A cross-category analysis of grocery products

This article examines the influence of coupons on private label shares of grocery products. The impact of national brand and private label coupons, distributed by manufacturers and retailers, is examined. A consumer framework and a typology of coupon effects are developed to explain different types of coupon usage behavior. Aggregate scanner panel data on 480 product categories are used in the analysis. Both the type of coupon and the method of distribution (by manufacturer or by retailer) are found to be important determinants of private label share response. Couponing activities by the national brand manufacturer are negatively related to private label share, thus indicating that they may be effective deterrents of private label penetration. However, couponing activities related to private labels do not help increase private label shares. The surprising finding is that national brand store couponing activity is positively related to private label share.
