However, its influence on the transformation of core sectors from the perspective of consumer well-being remains under-explored. Seeking to bridge this gap in the marketing and public policy literature, this study aims to propose a conceptual framework to explicate how data-driven, intelligent and connected IR 4.0 technologies are blurring traditional boundaries between digital, physical and biological domains.\u0000\u0000\u0000Design/methodology/approach\u0000This is a conceptual paper using primarily a literature review of the field.

Finally, the authors discuss public policy implications and outline future research directions.\u0000\u0000\u0000Originality/value\u0000The authors highlight specific gaps in the literature on IR 4.0. First, past studies in consumer well-being did not incorporate substantial changes that emerging IR 4.0 technologies bring, especially across increasingly blurring digital, physical and biological domains. Second, past research focused on individual technologies and individual well-being. What is unaccounted for is the potential for a synergetic, proactive effect that emerging technologies bring on the aggregate level not only to individuals but also to society and the environment. Finally, understanding the differences between responses to different outcomes of technologies has important implications for developing public policy. Synergetic, proactive effect of technologies on core sectors such as healthcare, education, financial services, manufacturing and retailing is noted.\u0000","PeriodicalId":35923,"journal":{"name":"Journal of Consumer Marketing","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43164426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Phase 1 of this research, participants responded to open-ended questions regarding the drivers of emotional eating. In Phase 2, a theoretically driven model was developed from Phase 1 findings and quantitative data was collected to test it.\u0000\u0000\u0000Findings\u0000Phase 1 findings indicate that negative terms such as “stressed” and “distract” were more prevalent in the high emotional coping group as opposed to the low emotional coping group. Building from Phase 1, findings from Phase 2 demonstrate a link between emotional eating and indulgent food consumption, underscoring the impact of habitual behaviors. Specifically, emotional coping frequency fully explains the relationship between emotional eating habits and indulgent eating frequency, while intentions to eat indulgent foods partially mediates the relationship between attitude toward indulgent foods and indulgent food consumption frequency.

Online information privacy became a serious concern after the introduction of e-commerce websites (Lwin et al., 2007; Turban et al., 2017) because such websites require individuals’ personal information while creating an account with them. Further advancements in digital technologies, such as smartphone applications, cloud computing technology, artificial intelligence (AI), wearable devices, drones, robotics and autonomous vehicles, brought new conceptions in the online information privacy concerns (Conger et al., 2013). Big data is another technological development enabling organisations to handle a massive amount of data in various formats, such as website texts, audio and video data from social networking sites, location data from mobile location-based services, medical laboratories data and RFID tags (Erevelles et al., 2016; Sathi, 2013). Regardless of the richness of big data, it raises severe issues of information privacy and is considered a “troubling manifestation of Big Brother” (Boyd andCrawford, 2012). The online information privacy concerns are one of the main challenges for organisations with every new technology brings its own privacy concerns and risks (Conger et al., 2013; Smith et al., 2011; Westin, 2003). However, little is known about consumer privacy in the context of digital marketing (Martin and Murphy, 2017). Therefore, the present special issue has been called to prompt a thorough investigation of consumer privacy in the present era of ultra-high-tech advancements.","PeriodicalId":35923,"journal":{"name":"Journal of Consumer Marketing","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2023-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44960321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Researchers have also established that narrative transportation affects persuasion, changes in attitudes and brand evaluations. To this end, several studies have focused on narrative consumption (i.e. being hooked into a narrative) and the aforementioned consequences of narrative transportation. However, research investigating the role that fantasy plays in consumers’ journey from narrative consumption to narrative transportation is scant. The purpose of this paper is to develop a multidimensional scale for measuring narrative-driven fantasy in order to detail which dimensions of fantasy facilitate narrative transportation. Further, this paper posits that prior research has overlooked the mediating role that fantasy plays within the narrative consumption and narrative transportation process.
