Marketing researchers are interested in the relative persuasiveness of different message modes, such as narratives and arguments. A desire to explicate and compare underlying mechanisms is central to this research, yet progress is hindered by a dearth of measures that can be used meaningfully across modes. In the current project, we identify and validate three cross-modal message perceptions - veracity, novelty, and memorability - that can mediate the relationship between different modes and outcomes. Three studies (Study 1: = 105; Study 2: = 322; Study 3: = 248) confirmed the factor structure, discriminant validity, and cross-modal (narrative vs. argument) value of all three message perceptions. The results of this study provide researchers with three cross-modal measures to support comparative message effects research.

The COVID-19 pandemic has led to an increase in the factors that typically facilitate the endorsement of materialistic values (e.g., higher media consumption, stress and anxiety, loneliness, death anxiety, and lower moods). In this paper, we examine how contextual changes affecting the antecedents of materialism influence its advocacy with a mixed-method approach. First, a correlational study (Study 1) suggests that increases in media consumption and stress and anxiety during the pandemic predicted current levels of materialism, however, these effects were limited. Second, contrary to our expectations, a longitudinal study (Study 2) shows that people's focus on money decreased during the pandemic. Last, a social media content analysis (Study 3) reveals a downward trend in users' online discourses about consumption-related behaviors, but an upward trend in brands promoting spending as a way to attain well-being. The observed effects could fuel deeper societal change in the labor market and in consumer behavior, and have further implications for individual and societal well-being in a post-pandemic world. We recommend future interventions aimed at diminishing materialistic attitudes to examine the effects of decreasing media consumption and to explore how other factors introduced by the pandemic (e.g., a health or well-being focus) might moderate its advocacy.

Apart from personal- and societal-level factors, we propose that collectivism also plays a role in the spread of COVID-19. Results from six studies using both secondary datasets and laboratory experiments conducted in two different countries demonstrate that collectivism is: (a) negatively associated with the spread of COVID-19 and (b) positively associated with the self-importance/expectation to engage in widely publicized behaviors to prevent the spread of the disease, as well as with greater likelihood to vaccinate against COVID-19. Finally, the higher likelihood of people high (vs. low) in collectivism to engage in preventive behaviors is driven by their belief that others consider it important to engage in such behaviors. The effects were robust and emerged by measuring collectivism both at the country level and at the individual level. We conclude by proposing features of public health campaigns likely to elicit compliance behavior to control the spread of COVID-19.

Anti-vaccination sentiment and vaccine hesitancy are on the rise. This is unfortunate given the world's coronavirus disease 2019 (COVID-19) pandemic response plan relies on a global vaccination program the likes of which has never been attempted. Using an anti-consumption lens, this study utilizes a qualitative approach and 53 interviews revolving around people's attitudes towards the COVID-19 vaccination plan. The findings reveal that COVID-19 vaccination hesitancy comes from two major factors: stable factors and contextual factors. Stable factors refer to factors that are consistently found in anti-vaccination movements and include political and philosophical opposition. Contextual factors refer to factors that are highly dependent on the COVID-19 situation and relates to a negative benefit to risk ratio informed by information overload and the influence of marketing phenomena such as branding and country of origin effects. Finally, theoretical and managerial contributions are offered for public policymakers and social marketers.

This study investigates the relationship between the COVID-19 threat and consumer evaluation of a product with authenticity appeals in advertisements. We propose that threatening situations like COVID-19 motivate consumers to lower their uncertainty and increase their preference for products with authentic advertising messages. Because individuals react differently to threatening environments according to their early-life experiences, commonly reflected in childhood socioeconomic status, we examined whether childhood socioeconomic status moderates the relationship between threat and consumer evaluation of authenticity in advertisements. First, secondary data from Google Trends provided empirical support for our predictions. In additional experimental studies, participants evaluated different target products in four studies that either manipulated (Studies 2 and 3) or measured (Studies 4 and 5) COVID-19 threat. Our results provide converging evidence that consumers positively evaluate products with authentic advertising messages under the COVID-19 threat. Consumers' motivation to lower their uncertainty underlies the effect of COVID-19 threat on their evaluation of authentic messages (Study 3). This attempt to reduce uncertainty is more likely to occur for consumers with relatively higher childhood socioeconomic status (Studies 4 and 5). These findings suggest that using authenticity appeals during a pandemic could effectively reduce consumers' perceived uncertainty and generate positive consumer evaluations.

Based on the theoretical framework of agency effect, this study examined the role of affect in influencing the effects of chatbot versus human brand representatives in the context of health marketing communication about HPV vaccines. We conducted a 2 (perceived agency: chatbot vs. human) × 3 (affect elicitation: embarrassment, anger, neutral) between-subject lab experiment with 142 participants, who were randomly assigned to interact with either a perceived chatbot or a human representative. Key findings from self-reported and behavioral data highlight the complexity of consumer-chatbot communication. Specifically, participants reported lower interaction satisfaction with the chatbot than with the human representative when anger was evoked. However, participants were more likely to disclose concerns of HPV risks and provide more elaborate answers to the perceived human representative when embarrassment was elicited. Overall, the chatbot performed comparably to the human representative in terms of perceived usefulness and influence over participants' compliance intention in all emotional contexts. The findings complement the Computers as Social Actors paradigm and offer strategic guidelines to capitalize on the relative advantages of chatbot versus human representatives.

The unprecedented crisis of COVID-19 posed severe negative consequences for consumers, marketers, and society at large. By investigating the effect of individuals' distance from the COVID-19 epicenter (i.e., the geographical area in which COVID-19 pandemic is currently most severe) on consumers' risk perception and subsequent behaviors, this research provides novel empirical findings that can offer practical insights for marketers. While intuitively, people expect individuals closer to the COVID-19 epicenter to generate a greater risk perception of the pandemic, empirical evidence from four studies provides consistent results for the opposite effect. We find that a closer (vs. farther) distance to the epicenter associates with lower (vs. higher) perceived risk of the pandemic, leading to less (vs. more) irrational consumption behaviors. We refer to this phenomenon as the "distance proximity effect," which holds for both physical and psychological distances. We further demonstrated that this effect is mediated by consumers' perception of uncertainty and moderated by individuals' risk aversion tendency. The current research contributes to the literature of consumers' risk perception and irrational consumption by highlighting a novel factor of distance proximity. It also offers some timely insights into managing and intervening COVID-19 related issues inside and outside an epicenter.

While the debate on online service failure and recovery strategies has been given considerable attention in the marketing and information systems literature, the evolving Covid-19 pandemic has brought about new challenges both theoretically and empirically in the consumption landscape. To fully understand customers' responses to service failure during a crisis we asked 70 millennials from three European Countries-Italy, France, and the UK-to describe their responses to service failure during the Covid-19 pandemic (30 completed a 4-week diary and 40 completed a 4-week qualitative survey). Drawing on phenomenological, constructivist, and hermeneutical approaches, and utilizing an actor-network theory perspective, the current study proposes a new framework for understanding customers' responses to online service failure and recovery strategies during the Covid-19 pandemic. Conclusions highlight implications for theory, policy, and management practice through extending comprehensions of service failure recovery processes by examining how marketing policies generate different social impacts during a crisis situation which facilitate the achievement of customer satisfaction and positive outcomes.

Mortality threats are among the strongest psychological threats that an individual can encounter. Previous research shows that mortality threats lead people to engage in unhealthy compensatory consumption (i.e., overeating), as a maladaptive coping response to threat. In this paper, we propose that reminders of heroes when experiencing mortality threat increases perceptions of personal power, which in turn buffers the need to engage in unhealthy compensatory consumption. We test and find support for our predictions in a series of four studies that include real-world Twitter data after a series of terrorist attacks in 2016-2017, and three experimental studies conducted online and in the field with behavioral measures after Day of the Dead and during COVID-19 pandemic. These findings advance the literature on compensatory consumption, mortality threats, and the psychological functions of heroes.

Sharing does not need to involve corporate providers but can also happen on a peer-to-peer (P2P) basis. P2P sharing platforms who match private providers and users are thus dealing with two different customer segments. An example of this is carpooling, the sharing of a car journey. Recent years have seen considerable research on why people use sharing services. In contrast, there is little knowledge of why people may offer a good for sharing purposes. Drawing on identity theory, this paper suggests that users and providers of carpooling need to be addressed differently. A pilot study and two studies, including both actual car owners and nonowners confirm that the extent to which one identifies as an environmentalist predicts car owners' willingness to offer carpooling, but does not affect nonowners' willingness to use carpooling services. These findings remain robust when controlling for various potential confounds. Furthermore, Study 2 suggests that an environmentalist identity plays an important role for car owners' actual decision to offer a ride via an online platform. These results suggest that marketers of P2P platforms need to pursue different strategies when addressing potential users and providers on the same platform.

This article explores how perceived disempowerment impacts the intention to adopt smart autonomous products. Empirically, the paper builds on three studies to show this impact. Study 1 explores the relevance of the perceived disempowerment in respect of smart autonomous products. Study 2 manipulates autonomy of smart products and finds that perceived disempowerment mediates the link between smart products' autonomy and adoption intention. Study 3 indicates that an intervention design-that is, a product design that allows consumers to intervene in the actions of an autonomous smart product-can reduce their perceived disempowerment in respect of autonomous smart products. Further, Study 3 reveals that personal innovativeness moderates the role that an intervention design plays in product adoption: an intervention design shows a positive effect on adoption intention for individuals with low personal innovativeness, but for those with high personal innovativeness no effect of an intervention design is present on adoption intention. The authors suggest that managers consider consumers' perceived disempowerment when designing autonomous smart products, because (1) perceived disempowerment reduces adoption and (2) when targeted at consumers with low personal innovativeness, an intervention design reduces their perceived disempowerment.
