Broad vs. Narrow brand positioning: Effects on competitive brand performance
Vis sammendrag
Purpose –Brand managers can choose among two fundamentally different brand positioning strategies. One is a broad brand strategy, focusing on many favorable brand associations. The other is a narrow brand strategy, focusing on just a few and thus more mentally accessible associations. Building on associative memory theory, the current article examines which of these brand positioning strategies performs better under dynamic market conditions.
Design/methodology/approach – Three experiments test the effect of brand positioning strategy on memory accessibility and competitive brand performance. Study 1 tests how brand strategy (broad vs. narrow) affects defensive brand performance. Study 2 tests how broad vs. narrow brands perform differently in a brand extension scenario (offensive brand performance). Study 3 uses real brands and situation-based attributes as stimuli in a defensive scenario.
Findings – The results show that a narrow brand positioning strategy leads to a competitive advantage. Narrow brands with fewer and more accessible associations resist new competitors more easily and have higher brand extension acceptance than do broad brands.
Research implications – The article shows how to use accessibility as evidence of associative strength and test how accessibility influences competitive brand performance in a controlled experimental context.
Practical implications – Brand managers would benefit from a narrow brand positioning strategy in accordance with the USP school of thought used by many marketing practitioners.
Originality – The paper demonstrates that narrow brand positioning performs better than broad brand positioning in dynamic markets, and to our knowledge is the first to do so.

EXPRESS: Consumer Centered Policy Inquiries: a Call to Explore Policy Through a Consumer Lens and Consumers Through a Policy Lens
Vis sammendrag
The Journal of Public Policy and Marketing has long welcomed scientific inquiry at the intersection of public policy and consumer behavior. While the existence of this intersection feels like a given, defining the contours and borders of this intersection is arguably much grayer. It is not uncommon for readers and authors new to JPP&M to puzzle over whether their consumer research is policy-oriented enough, or question how their policy interest can be studied using methodologies characteristic of consumer research. To provide some insight, we define the body of work at the intersection of public policy and consumer behavior as consumer centered policy inquiries and provide an organizing framework for how to both define and characterize it.

Revisiting Gaussian copulas to handle endogenous regressors
Vis sammendrag
Marketing researchers are increasingly taking advantage of the instrumental variable (IV)-free Gaussian copula approach. They use this method to identify and correct endogeneity when estimating regression models with non-experimental data. The Gaussian copula approach’s original presentation and performance demonstration via a series of simulation studies focused primarily on regression models without intercept. However, marketing and other disciplines’ researchers mainly use regression models with intercept. This research expands our knowledge of the Gaussian copula approach to regression models with intercept and to multilevel models. The results of our simulation studies reveal a fundamental bias and concerns about statistical power at smaller sample sizes and when the approach’s primary assumptions are not fully met. This key finding opposes the method’s potential advantages and raises concerns about its appropriate use in prior studies. As a remedy, we derive boundary conditions and guidelines that contribute to the Gaussian copula approach’s proper use. Thereby, this research contributes to ensuring the validity of results and conclusions of empirical research applying the Gaussian copula approach.

'What lies behind the filter?’ Uncovering the motivations for using augmented reality (AR) face filters on social media and their effect on well-being
Vis sammendrag
Augmented reality (AR) filters are a popular social media feature affording users a variety of visual effects. Despite their widespread use, no research to date has examined either ‘why’ people use them (i.e., motivations) or ‘how’ their usage makes people feel (i.e., well-being effects). Through the uses and gratifications theory supported by a sequential mixed-method approach (interviews N = 10 and survey N = 536), we provide three overarching contributions. First, based on prior literature and a qualitative study, we identify nine motivations that can potentially drive AR face filter usage on Instagram. Our survey indicates that seven of those motivations (e.g., creative content curation, social interactions) are significant drivers of usage behaviours, while two (true self-presentation and silliness) did not have a significant impact. Second, we provide nuanced insights into the multi-faceted nature of the self-presentation motives underpinning AR face filter use (ideal, true and transformed self-presentation). Lastly, we show filter usage can have both positive and negative well-being effects depending on the underlying motivation. The results offer important implications for policymakers, site designers and social media managers.

Is similarity a constraint for service to service brand extensions?
Vis sammendrag
Are service brands constrained in launching new service offerings? Both research evidence and managerial wisdom suggest brands should extend to similar categories. However, in five studies using real-life brands - four experiments and one large-sample survey - we provide evidence that similarity is less of a constraint for service brands extending to other service categories (service-to-service extensions), compared to cases involving parent brands or extension categories of a product nature. Importantly, we demonstrate that such an effect occurs because service brands possess associations relevant across the spectrum of service categories. Our results suggest that service brand managers have the opportunity to stretch their brands to dissimilar service offerings; yet, they need to ensure the marketing execution does not make the brands’ service associations inaccessible to consumers. The findings suggest that even product brands can build service associations by adding service components to their offering, thus becoming “servitized” and better able to extend to dissimilar service categories. Overall, our work contributes to the academic debate documenting that the principles governing the management of product vs. service brands are not identical.

How, Why, and When Disclosure Type Matters for Influencer Marketing
Vis sammendrag
Consumers’ changing media consumption behaviors and skepticism toward traditional forms of advertising have prompted the growth of influencer marketing. Even as regulatory authorities call on brands and influencers to disclose the posts as advertising, no consistent guidelines exist. The distinct effects of self-generated versus platform-initiated disclosures also remain unclear, nor has research addressed the interplay of key influencer characteristics and marketing disclosures. This article reports on findings from the first academic field study of influencer marketing disclosures, as well as three experimental studies, which indicate that disclosure is a double-edged sword. When provided through a platform-initiated branded content tool, disclosure consistently exerts the strongest effect on perceptions of advertising, negatively relating to influencer trustworthiness and consumer engagement. The effects of disclosure type also depend on the number of followers and number of previously endorsed products (i.e., influencer characteristics). Yet consumers also express appreciation for transparency when influencers disclose posts as advertising, which increases perceived trustworthiness of the influencer and engagement with the post. The implications of these findings should inform choices by public policy makers, brand managers, and influencers.

Customer defection due to service elimination and post-elimination customer behavior: An empirical investigation in telecommunications
Vis sammendrag
Service industries require rapid innovations in their service portfolios to gain and maintain competitive advantages. Service elimination is a potential tool for portfolio renewal, though it might threaten increased defection rates. To contribute to both service elimination and customer defection literature, this paper proposes a model of customer responses to service elimination, with practical implications for decision-makers in rapidly innovating telecommunication markets.
In particular, the main study, conducted in the context of Hungary’s telecommunications sector, reveals that customers’ tenure, usage intensity, and age reduce the negative effects of a price increase on their defection; the price increase, degree to which customers interact with service providers, customer defection, and competitive effects in turn increase post–service elimination usage intensity.
These findings suggest implementation strategies that can reduce customer defection following price increase due to service elimination, by focusing on new customers, light users, and the quality of customer interactions.

MANAGING A GLOBAL RETAIL BRAND IN DIFFERENT MARKETS: META-ANALYSES OF CUSTOMER RESPONSES TO SERVICE ENCOUNTERS
Vis sammendrag
This study investigates how retailers can leverage their brand to shape customers’ satisfaction with service encounters. It develops and tests hypotheses about how brand, store, and consumer factors moderate customer responses to experience clues during retail service encounters. Six meta-regression analyses synthesize and compare results from 842 satisfaction equations describing customers’ encounters with a global retailer operating 400 stores in 32 countries. The results show how customers weigh their perceptions of service encounters differently depending on brand, store, and consumer factors. In markets where customers believe the retailer has high holistic brand quality, they place less weight on experience clues within the store. In markets where customers believe the retailer’s service brand promise, they place more weight on in-store experience clues. In markets where the retailer promises utilitarian value, customers weigh functional experience clues more heavily. In markets with an online purchasing channel, the effect of experience clues common to offline and online store environments is magnified, and unique clues are diminished. In addition, customers heavily weigh experience clues that fit their goals. In general, retail success factors include high brand quality (which makes customers more forgiving), a service brand promise that is mirrored in the store image (which makes customers attend to the experience clues aligned with them), and the careful monitoring and managing of retail touchpoints (to customize experience clues to each market). In this way, retailers can use customer-based strategies to effectively design and manage their global retail brand in different markets.

Hvordan balansere mellom digitale og sosiale innovasjoner
Magma - Tidsskrift for økonomi og ledelse, p. 107-116.
Vis sammendrag
Ledere som ønsker at deres bedrift skal være relevant og attraktiv, må bedre balansere forholdet mellom to innovasjonsstrategier: digitalisering av kundefronten og innovasjoner forankret i samfunnsansvar. Sistnevnte kaller vi sosiale innovasjoner. For ledere fortoner dette seg som et valg mellom å sette søkelys på innovasjoner som er til bedriftens beste, gjennom å digitalisere kundeløsninger, eller å gi oppmerksomhet til innovasjoner som er sosiale, miljø- og samfunnsnyttige. Sagt på en annen måte: Hvilke innovasjoner bidrar mest til å øke kundelojaliteten og dermed kundebasens økonomiske verdi? I denne artikkelen belyser vi problemstillingen med utgangspunkt i virksomhetenes viktigste interessentgruppe – kundene. Vi har intervjuet mer enn 10 000 kunder av norske bedrifter. Tallenes tale er klar: Sosiale innovasjoner er tre ganger så viktige som digitale i sin samvariasjon med opplevd innovasjonsevne, relativ attraktivitet og kundelojalitet. Samtidig viser resultatene at digitalisering kan være en svært viktig forutsetning for å lykkes med sosiale innovasjoner. En bedrift som vil oppnå vekst i omsetning og lojale kunder, bør derfor ikke stoppe ved digitalisering av kundeopplevelsen, men bruke de mulighetene digitalisering gir til å skape sosiale innovasjoner som bidrar gir positive bidrag til miljø og samfunn. I artikkelen belyser vi også ulike innovasjonsorienteringer som vi finner blant bedrifter og virksomheter, om de er digitalt eller sosialt forankret. Til slutt diskuterer vi hvilke ledelsesmessige implikasjoner de ulike orienteringene gir.

Situated Food Safety Risk and the Influence of Social Norms
Vis sammendrag
Previous studies of risk behaviour observed weak or inconsistent relationships between risk perception and risk-taking. One aspect that has often been neglected in such studies is the situational context in which risk behaviour is embedded: even though a person may perceive a behaviour as risky, the social norms governing the situation may work as a counteracting force, overriding the influence of risk perception. Three food context studies are reported. In Study 1 (N = 200), we assess how norm strength varies across different social situations, relate the variation in norm strength to the social characteristics of the situation, and identify situations with consistently low and high levels of pressure to comply with the social norm. In Study 2 (N = 502), we investigate how willingness to accept 15 different foods that vary in terms of objective risk relates to perceived risk in situations with low and high pressure to comply with a social norm. In Study 3 (N = 1200), we test how risk-taking is jointly influenced by the perceived risk associated with the products and the social norms governing the situations in which the products are served. The results indicate that the effects of risk perception and social norm are additive, influencing risk-taking simultaneously but as counteracting forces. Social norm had a slightly stronger absolute effect, leading to a net effect of increased risk-taking. The relationships were stable over different social situations and food safety risks and did not disappear when detailed risk information was presented.

Subliminal fatty acid-induced gut-brain signals attenuate sensitivity to exteroceptive rewards in food but not in sex or financial domains, in healthy men
Vis sammendrag
Background: Reward sensitivity can generalize across domains, but evidence for generalization of suppressive reward-related stimulation is sparse, especially in the context of interoceptive nutrient-related stimuli. We hypothesized that subliminal fatty acid-induced gut-brain signals could attenuate sensitivity to exteroceptive rewards, not only within the food domain but also across domains.
Method: Intragastric infusion of 2.5g lauric acid (fat condition) or saline (saline condition) was administered to 59 healthy heterosexual male volunteers in a blinded fashion. To assess whether the resulting interoceptive signals attenuate reward sensitivity within the food domain, participants rated the palatability of food images and performed a progressive ratio task. To assess whether such attenuation effect generalizes to the sexual and financial reward domains, participants rated attractiveness of female face images and performed an intertemporal monetary choice task.
Results: Participants’ ratings of food images were lower (F1,172 = 4.51, p=0.035, Cohen's d: -0.20) in the fat condition. The progressive ratio task terminated earlier in the fat condition compared to saline (F1,52 = 4.17, p=0.046, odds ratio = 0.31, 95%CI [0.11, 0.98]). Participants’ ratings of female face images did not differ between conditions (F1,172 = 1.85, p = 0.19, Cohen's d: -0.15). Moreover, the monetary discounting rate did not differ significantly between conditions.
Conclusion: Overall, these findings suggest a domain-specific effect of subliminal fatty acid infusion on decreasing reward sensitivity.
