Consumer Evaluations of Competing Brands: Perceptual versus Predictive Validity

This study applies the concepts of consumer predictive and confidence values of information to consumer evaluations of food quality. Examining hypothetical findings from a thought experiment, the study offers advances in cue utilization, predictive validity, and achievement of consumer's perceived quality and actual quality. Separately, metrics for these concepts were applied in a consumer product‐quality evaluation study of three brands of peanut butter. Actual quality was operationally defined in terms of Consumers Union ratings of the peanut butter. Using a between‐groups, posttest only experimental design, female graduate students (n = 98) tasted and rated one of three peanut butters on the basis of quality and nine product attributes. These informants received no knowledge of brand names or comparative qualities prior to the test. The analysis indicates a nonsignificant correlation between actual quality of the brands and quality as perceived by the informants. The major cues used by informants in making their qualitative judgments (cue utilization) differed from the significant dimensions associated with actual quality (predictive validity). The findings inform the suggestion for consumer training in the process of making accurate quality evaluations.     

Consumer Purchase Intentions and Perceptions of Product Quality and National Advertising

The relationship between consumer perceptions of brand quality and the level of national advertising is examined using 93 subjects for three brands of peanut butters. The association between these perceptions and purchase intentions is also reported. Results suggest that a strong link between quality and national advertising exists in the minds of consumers. Subjects associated peanut butter brand quality with the perceived level of national advertising. Additionally, purchase intentions were positively correlated with perceptions of brand quality.

A characterization of peanut consumption in four countries: results from focus groups and their implications for peanut allergy prevalence

Rates of peanut allergy in the Western world have increased over the last 30 years, although it is unclear why. While eating behaviours are likely to be connected to allergy prevalence, the precise relevant factors are uncertain. This study aimed to investigate dietary differences and changes in dietary habits in peanut consumption (in apparent and hidden forms) in four different countries (Bulgaria, Poland, Spain, UK), specifically chosen because of their different ‘peanut experiences’. Focus groups revealed a common perception that dietary habits have become less healthy, with more consumption of processed foods and an increase in snacking. In addition, ethnic cuisine was perceived to have had an important impact on European eating habits, while participants identified an increase in consumption of more ‘exotic’ forms of peanuts and their products. These findings point to an increase in exposure to peanuts, particularly in hidden forms, that superficially parallels increased prevalence rates. However, it was also clear that participants lacked knowledge about the composition of food and non‐food products. The dietary trends identified here thus warrant further quantitative investigation, particularly in the context of differential national patterns of allergy prevalence – data on which is currently being gathered within the EC‐funded EuroPrevall project.     

Media influences on consumption trends: Effects of the film Food,Inc. on organic food sales in the U.S.

In this paper, we empirically investigate the effect of Food, Inc. – an influential documentary film on the US food industry – on organic food sales. We use a novel dataset of Google search volume to measure the influence of the film. Organic food sales are measured using store-level data for three categories in 33 major US markets. For two out of the three studied categories – yogurt and peanut butter – we find that areas with more Google searches for the film experienced a greater increase in the share of organic sales subsequent to the film's release. The effect of the film is more pronounced for the yogurt category, which is closer to the farm and more relevant to animal welfare — one of the key issues featured in the film. The effects are economically significant: ceteris paribus, a one standard deviation increase in our Google search stock measure translates into a 0.66% increase in organic market share for the yogurt and a 0.15% increase for the peanut butter category. In addition, we provide a measure of the decay of the film's effect by deriving the 90% duration interval of the focal search stock variable. We find that, for both categories, the film's effect on organic shares faded within six months.     

Comparative study of properties and acceptability of Haitian and US honey‐roasted peanuts

A honey‐roasted peanut product, flavoured with ginger and anise, was recently developed in Haiti in an effort to increase the consumption of locally grown peanuts. The objective of this study was to compare quality and consumer acceptability of the Haiti product with a traditional US‐manufactured brand. Haitian panellists (199) evaluated colour, appearance (dry/oily), crunchiness, peanut flavour and sweetness of the products using five‐point just‐about‐right scales. Colour (Minolta chromameter), hardness (TA.XT2i texture analyser fitted with a TA42 knife blade) and moisture (Denver IR‐30 moisture analyser), lipid (ethyl ether extraction) and sugar (Dionex DX‐500 high pressure liquid chromatography system) contents of the products were also determined. The Haiti product was significantly (P < 0.05) darker brown, harder and contained more (P < 0.05) sucrose and glucose but less (P < 0.05) lipid and fructose than the US product. Panellists indicated that crunchiness, peanut flavour and sweetness of both products were just right. The US product had acceptable appearance but was rated too light (hue angle = 69.6 ± 0.70, L‐value = 58.2 ± 0.47) in colour, whereas the Haiti product appeared too dry and dark (hue angle = 62.6 ± 2.79, L‐value = 44.6 ± 2.22). The Haiti peanuts were not deskinned, and their testae may have decreased the acceptability of the product's appearance and colour. The Haiti product was significantly (P < 0.05) just right to the female panellists and to the 21‐year plus panellists from all income groups. Deskinning of the peanuts and increased oil addition during roasting may improve the acceptability of the Haiti product, especially to 14–20 year olds. Decrease in sugar content may also make the Haiti product more appealing to this age group and to male Haitians.     

Supply Chain Integration and the SCOR Model

The Supply Chain Operations Reference (SCOR) model has been widely adopted in many companies. Anecdotal evidence and trade journals have reported significant improvements after firms have adopted the SCOR model. Although practitioners have been enthusiastic about implementing and using the SCOR model in their operations, the SCOR model has not been empirically validated. The purpose of this study is to empirically validate the SCOR model (i.e., test the structure of the SCOR model). Data from 125 North American manufacturing firms were collected. The results show that the relationships among the supply chain processes in the SCOR model are generally supported. The Plan process has significant positive influence on the Source, Make, and Deliver processes. The Source process has significant positive influence on the Make process and the Make process has significant positive influence on the Deliver process. The Source process mediates the impact of the Plan process on the Make process and the Make process mediates the impact of the Plan process on the Deliver process. The findings provide managers with empirical evidence that the SCOR model is in fact valid.     

Groundnut consumption frequency in Ghana

Groundnut (peanut) is an important food and oil crop in Ghana, but little is known about the factors influencing consumption. The study surveyed market participants; investigated the frequency and forms of groundnut consumed; and evaluated the factors influencing consumers’ decisions to eat groundnuts in Ghana. About 80% of respondents consume groundnut and/or its products at least once a week and 32.0% consume it three times a week. Logistic models showed that age, education and the form in which groundnuts are consumed influence the frequency of groundnut consumption. Total revenue and the form in which groundnut is eaten influence farmers consumption decision whereas groundnut consumption by poultry farmers is influenced by knowledge of the health effects of groundnuts on birds and the form in which groundnut is eaten by the poultry producers. Processors’ frequency of consumption is influenced by the form in which groundnut is consumed and their knowledge of reasons for sorting. The results are important for market segmentation for demand projection along the marketing chain.
