Abstract: This paper applies the D Duplication Coefficient from the Duplication of Purchase Law as a benchmark to help investigate patterns in simultaneous product category purchases. Shopper transaction data enable a deep analysis of what goes into shoppers' baskets however, robust benchmarks are critical to see patterns in such rich data. We demonstrate the application of D Duplication Coefficient data to 30,000-plus UK and US supermarket transactions. The cross-category benchmarks allow meaningful deviations to be identified, isolating categories that are more or less intensely co-purchased than expected, which can then be used to guide decisions regarding store layout, prioritise in-store activations and plan product category promotions.

Abstract: This paper seeks to compare how brand users and non‐brand users currently position private labels and national brands in three packaged goods categories. It aims to provide guidelines for positioning strategies for both private labels and national brands through the outcomes. Data were collected in a telephone survey of 600 randomly recruited primary shoppers. Binary logistic regression was used to examine the informational cues consumers use to categorize private labels and national brands. The memory structures of users and non‐users of private labels were then separately modelled. Results suggest that the perceptual categorization into private label brands and national brands differs once private labels have been purchased. Users of private label brands did not see them as being any less trustworthy than national brands. However, non‐users of private labels did use trust to discriminate between the two types of brands, and tended to use negative attribute information to categorize the brands into groups. Regardless of experience, however, private labels form a subgroup in consumers' memory, with low price and low quality as the main drivers of this categorization. This paper extends past studies by measuring the perceptions of private labels as in idual brands within a market, which more closely represents actual consumer memory structures. It also uses both positive and negative product attributes, which has not featured in prior work on private labels perceptions. The findings have implications for retailers looking to launch and manage private labels and manufacturers who need to compete with them.

Abstract: Rhinoviruses (RVs) are ubiquitous human respiratory viruses, the major cause of common colds, acute exacerbations of asthma and other respiratory diseases. The development of antibodies to RV following primary infection is poorly understood and there is currently no RV vaccine available. We therefore used mouse models of intranasal RV infection and immunisation to determine the induction, magnitude and specificity of antibody responses. Strong cross-serotype RV-specific IgG responses in serum and bronchoalveolar lavage were induced towards the RV capsid protein VP1. IgA responses were weaker, requiring two infections to generate detectable RV-specific binding. Similarly two or more RV infections were necessary to induce neutralising antibodies. Immunisation strategies boosted homotypic as well as inducing cross-serotype neutralising IgG responses. We conclude that VP1 based antigens combined with adjuvants may permit successful antibody-mediated vaccine design and development.

Abstract: Retailers are increasingly adding banks, gas stations, mobile services and even real estate agencies to their portfolio and branding these new ventures with the retailer name, such as Tesco Bank or Asda Money. The purpose of this paper is to test the ability of a retailer brand to stretch from traditional packaged goods categories to very different categories such as banking. Using data from an online survey collected from 953 UK grocery buyers, this paper examines consumers’ behaviour towards UK retailer brands across four categories: soft drinks, chocolate, fuel and banking. The results show that cross-category retailer brand purchasing is stronger between categories with similar buying behaviour (e.g. soft drinks and chocolate) than in categories with very different buying behaviour (e.g. soft drinks and banking). The behavioural spill over effects are stronger for retailer brands from the same chain and persist even for unrelated categories. However, apart from fuel, the strongest cross-purchasing occurs across competing retailer-branded offers within the same category. The main implication of this study is that behavioural spill overs for retailer brands are possible even between unrelated categories. The finding about the effects being strongest within a given chain implies that umbrella branded strategy is a key to take advantage of the effects. These findings extend past literature about the cross-category buying of umbrella branded store brands to very different categories. This paper highlights the challenges retailers face regarding their ability to extend the retailer brand across categories. The findings also provide insights for cross-selling retailer brands in unrelated categories to current store brand buyers. This is the first study to examine the use of retailer brands across a wide spectrum of categories from Soft Drinks to Fuel.

Abstract: The purpose of this paper is to examine what happens to key brand performance metrics as brands change in market share, in the context of packaged goods. The metrics are: penetration—the number of buyers a brand has and loyalty—measured as purchase frequency (PF) and share of category requirements (SCR). The study utilizes 24 data sets in 17 packaged goods categories in three emerging markets: China, Malaysia and Indonesia. The authors examine changes in penetration, loyalty and SCR in the context of volume and value market share change. In addition, the authors examine whether initial price point and price movements influence the results. The primary finding is that market share change is accompanied by a greater change in penetration than in any other metric. This finding is very consistent across categories and countries. The relative importance of the two loyalty metrics varies by country. SCR was a stronger factor in Indonesia, while PF was stronger in Malaysia. Analysis indicated that pricing strategy (initial price and promotional depth) did not alter the main pattern of results, suggesting the results hold for brands with different price levels and tactics. Irrespective of circumstance, to grow in value or volume market share, brands should aim to grow in penetration, while the importance of changes in specific loyalty measures depends on market conditions. This research extends past research on brand growth to the very different economic, geographic and cultural conditions of three crucially important emerging markets. Its main value lies in recommendations on how much to invest in building the size of the customer base vs consumer retention.

Abstract: This paper examines the incidence of consumers’ rejection of private labels (PLs) of different price-quality tiers and the underlying reasons for this rejection. The rejection of PLs is compared to the rejection of national brands (NBs) in five food product categories across the UK and Australia. The findings indicate that only 8% of PL non-users in the UK market, and 20% in the Australian market, actively reject PLs. This rejection incidence is higher for PLs than for NBs in three of the five categories. The reasons for brand rejection differ between PLs and NBs. PLs are rejected due to a perception of low quality inferred from extrinsic product cues. In contrast, NBs are rejected primarily because of a negative past experience with a brand. The findings highlight the importance of extrinsic cues for PLs to minimise the incidence of consumer rejection. The generally low rejection of PLs implies that PLs are a real threat to NBs. This paper extends the rejection literature to PLs and quantifies the rejection levels and reasons.

Abstract: The paper considers consumer brand rejection of ‘green’ and non-green brands. We find empirically that ‘green’ brands are not considered largely because they are unfamiliar, rather than being consciously rejected. Consumers do not think about these brands in a buying situation, suggesting that their single ‘green’ message is not enough to make it into the shoppers’ consideration set. Additionally, not being ‘green’ was not a reason for rejection of non-green brands. These findings highlight the importance of brand advertising to build multiple, relevant memory structures for any brand, thereby increasing the probability of being thought of during a buying occasion.

Abstract: Despite the growing availability of scanner-panel data, surveys remain the most common and inexpensive method of gathering marketing metrics. The purpose of this paper is to explore the size, direction and correction of response errors in retrospective reports of category buying. Self-reported purchase frequency data were validated using British household panel records and the negative binomial distribution (NBD) in six packaged goods categories. The log likelihood theory and the fit of the NBD model were used to test an approach to adjusting the errors post-data collection. The authors found variations in systematic response errors according to buyer type. Specifically, lighter buyers tend to forward telescope their buying episodes. Heavier buyers tend either to over-use a rate-based estimation of once-a-month buying and over-report purchases at multiples of six or to use round numbers. These errors lead to overestimates of penetration and average purchase frequency. Adjusting the aggregate data for the NBD, however, improves the accuracy of these metrics. In light of the importance of purchase data for decision making, the authors describe the inaccuracy problem in frequency reports and offer practical suggestions regarding the correction of survey data. Two novel contributions are offered here: an investigation of errors in different buyer groups and use of the NBD in survey accuracy research.

Abstract: Private labels are becoming more sophisticated, spanning many price-quality tiers and categories. As such, private label branding is evolving and retailers have to pay greater attention to factors that affect private label perceptions. One of such factors is the value-for-money perception of the supermarket, which is important both in terms of its competitiveness and the private labels it carries. The aim of this paper is to examine the relationship between value-for-money perceptions of a supermarket and perceptions that the private labels it offers are also value-for-money. We find a positive relationship between value-for-money perceptions of a supermarket and value-for-money perceptions of its private labels, which is stronger for private label non-users. Given that most private labels are not advertised, knowing that non-users of private labels form associations based on the store image is important for private label managers who want to grow the customer base of their private labels. For premium private labels we find that if a premium private label is the only private label in a category, it is perceived just like the traditional private label, suggesting a benefit in offering at least two tiers of private labels. Our findings provide implications for retailers in regards to their private label branding strategies.
