The notion of collaborative consumption or sharing economy—where consumers share access to ownership of properties such as cars, clothes and accommodations—has gained tremendous popularity in recent years. Development of communication technologies and peer‐to‐peer communities has enabled consumers to coordinate sharing activities through various online platforms. Collaborative consumption involves sharing of both intangible (e.g., music, space and car rides) and tangible assets (e.g., household items, clothes and furniture). Activities such as renting, swapping, trading and purchasing/selling used consumer goods are included in the latter. Despite increasing academic attention on collaborative consumption, little research has been pursued in the context of consumer goods. The nature of consumption for tangible goods can be entirely different from that of intangible goods because people can exercise greater control over tangible goods, which results in greater psychological ownership than that for intangible goods. To address this gap, the objective of this study is to develop a scale that examines consumer motivations for collaborative consumption of consumer goods. Following Churchill's paradigm of scale development, the procedures of scale item generation, purification and validation were conducted via in‐depth interviews, literature review and surveys. The study identified five underlying dimensions of collaborative consumption of consumer goods: concern‐for‐sustainability, social, variety‐seeking, fun and cost‐saving. Study findings and implications are discussed, and future research avenues are suggested.

To investigate the impact on mental health of the prolonged COVID-19 outbreak, the current study investigated peritraumatic distress, preventive behaviors, and psychological distress (depression, anxiety symptoms, and suicidal risk) among 1,000 Koreans in May 2020 in comparison with the levels of psychological distress reported among 257 Koreans during the periods before COVID-19 in South Korea and with those reported in other countries during the COVID-19 pandemic. Our results indicated that 27.3%, 34.2%, and 28.8% of the participants reported at least mild peritraumatic distress and depressive and anxiety symptoms, respectively. Of the participants, 23.6% were classified in the suicidal risk-positive group. Female participants and those in their 20s showed greater psychological distress than males or other age groups, respectively. Additionally, compared to the results reported from other countries, our results showed overall consistency in levels of psychological distress but relatively low anxiety symptoms and high depressive symptoms. Finally, our analysis indicates that psychological distress was exacerbated by job loss or decline in household incomes due to COVID-19.

Remote epitaxy is a recently discovered type of epitaxy, wherein single-crystalline thin films can be grown on graphene-coated substrates following the crystallinity of the substrate via remote interaction through graphene. Although remote epitaxy provides a pathway to form freestanding membranes by controlled exfoliation of grown film at the graphene interface, implementing remote epitaxy is not straightforward because atomically precise control of interface is required. Here, we unveil the role of the graphene–substrate interface on the remote epitaxy of GaAs by investigating the interface at the atomic scale. By comparing remote epitaxy on wet-transferred and dry-transferred graphene, we show that interfacial oxide layer formed at the graphene–substrate interface hinders remote interaction through graphene when wet-transferred graphene is employed, which is confirmed by an increase of interatomic distance through graphene and also by the formation of polycrystalline films on graphene. On the other hand, when dry-transferred graphene is employed, the interface is free of native oxide, and single-crystalline remote epitaxial films are formed on graphene, with the interatomic distance between the epilayer and the substrate matching with the theoretically predicted value. The first atomic layer of the grown film on graphene is vertically aligned with the top layer of the substrate with these atoms having different polarities, substantiating the remote interaction of adatoms with the substrate through graphene. These results directly show the impact of interface properties formed by different graphene transfer methods on remote epitaxy.

Consumers showed a dramatically increased interest in contactless shopping in reaction to the COVID‐19 pandemic. Based on the protection motivation theory, this study investigated how contactless shopping grew as a protectionary action against COVID‐19. Findings from a nationwide online survey ( n = 311) confirmed the impact of politicization of the pandemic on consumer responses for contactless shopping intention and the significance of threat and coping appraisals in taking protectionary actions. This study adds knowledge to the existing literature on contactless shopping and protection motivation theory. Results imply that retailers must invest in contactless shopping and provide an in‐store shopping environment that prioritizes the health and safety of shoppers and employees to decrease the threat of virus infection during shopping. However, in doing so, retailers are recommended to develop different marketing strategies regarding contactless shopping based on consumers' political orientations.

PurposeOne of the major concerns in the emerging phenomenon of collaborative consumption (CC) is the issue of contamination (i.e. feeling “grossed out” when sharing items with others). Guided by the law of contagion and the consumer contamination effect theory, this research investigated the ways in which companies can manipulate in order to reduce the negative contamination when renting or purchasing used fashion items from others. Specifically, this research examines this issue of contamination through the ownership type of the shared goods (e.g. corporate-ownership or B2C exchange, and consumer-ownership or C2C exchange) and its effect on consumers' CC intentions in two distinct sharing contexts (i.e. rental and secondhand purchase).Design/methodology/approachA total of 181 American female consumers were assigned to an experimental CC scenario, and their rental/secondhand purchase intentions were compared through ANCOVA analysis.FindingsIn both rental and secondhand purchase contexts, consumers displayed greater intentions to shop in B2C setting (i.e. corporate-ownership) with no direct contact with the previous owner, than in C2C setting (i.e. consumer-ownership) with a greater association with the previous owner and the shared items. Such inclination was more prevalent when purchasing a shirt than a handbag, suggesting that consumers feel more grossed out when there is greater physical contact with the shared item.Originality/valueThe findings of the study suggest a possible solution to alleviate the contamination effect, and the discovery of the degree of contact as a moderator provides new insight into contamination research.

The high uncertainty around the COVID‐19 pandemic elicited an unprecedented level of panic buying during the early months. Using the framework of stress and coping, the current study conceptualized and tested a theoretical model that predicts individuals' panic buying in two countries. A survey of US (n = 311) and Korean consumers (n = 347) revealed that negative emotions (loneliness and anxiety) contributed to panic buying, yet two important coping resources, resilience and social support, were effective in protecting consumers from engaging in a maladaptive coping strategy. The hypothesis that collectivism (vs. individualism) would make consumers rely on social (vs. personal) coping resources was partially supported. The results highlight the unique circumstance of the global pandemic in which social support works as both a resource for healthy coping and a source to increase negative emotions, and call for future investigation of the complex role of social support in the context of stress and coping theory.
