The effect of financial incentives, specifically in a company-sponsored online co-creation brainstorming (COCB) context, however, remains unexplored. In this study, we use LEGO Ideas, a prominent COCB, as an exemplar and employ a between-subjects randomized experimental design to examine the effect of different types of financial incentives on intrinsic motivation’s impact on participation intention in a COCB context, either directly or indirectly through personal innovativeness in the domain of information technology. Our findings suggest that focused financial incentives, representing situations where financial rewards are administered exclusively on the basis of excellent performance, offer the best outcome for predicting participation intention. These findings contribute to our knowledge of the use of financial incentives in sponsored online co-creation generally, and specifically in COCBs.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"394 - 415"},"PeriodicalIF":5.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42258624","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing studies on electronic commerce have mainly focused on consumer behavior; literature is sparse regarding why some entrepreneurial sellers have withdrawn from the online marketplaces while others persist. In this paper, we investigate the antecedents and outcomes of entrepreneurial persistence in online marketplaces. Using primary survey data and secondary store traffic and trade volume data from a large online marketplace, we find that entrepreneurial persistence enhances performance in online marketplaces. Instrumental support from peer entrepreneurs in the same online community strengthens this positive link. Entrepreneurial passion and sense of belonging to online marketplaces are significant precursors of entrepreneurial persistence. This study advances knowledge development in digital entrepreneurship by offering a systematic investigation of entrepreneurial persistence in online marketplaces. It also provides implications to individual entrepreneurs in terms of how to sustain efforts and succeed, and to platform companies in terms of how to better serve their entrepreneurial sellers.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"469 - 496"},"PeriodicalIF":5.0,"publicationDate":"2021-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49445408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although extant studies have largely focused on the effects of choice overload, few shed light on choice overload in online shopping situations. In light of online shopping’s untouchable nature and sorting mechanisms, we argue that choice overload in online shopping is associated with consumer vigilance and assortment desirability. Across four experiments, we found that the size of the online choice set significantly influences consumers’ choice difficulty and choice deferral. We also discovered that consumer vigilance and assortment desirability moderate these relationships. Specifically, high vigilance increases the negative impact of assortment size on consumer decision, whereas assortment product desirability alleviates this consequence. We contribute to the literature by extending prior predictions of choice overload and proposing a framework involving choice overload, vigilance, and desirability for future research.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"364 - 390"},"PeriodicalIF":5.0,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44276972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Editor’s Introduction","authors":"Vladimir Zwass","doi":"10.1080/10864415.2021.1943164","DOIUrl":"https://doi.org/10.1080/10864415.2021.1943164","url":null,"abstract":"Crowdsourcing, or co-creation of value with the firm’s external stakeholders and other contributors, has been gaining in importance over the past two decades. Enabled by the ecosystems of the web, crowdsourcing brings the wider and more diverse pool of knowledge and experience than any firm can muster internally. The creativity of the crowdsourcing community is a key to its actual contribution. Opening this issue of International Journal of Electronic Commerce, Sut I Wong, Aldijana Bunjak, Matej Černe, and Christian Fieseler present their study of some of the prerequisites to the crowdworkers’ creativity. More specifically, the researchers examine the role of feedback received by the contributing participants on the digital crowdwork platforms. Their theory-driven empirics and analysis bring out a highly nuanced picture. Feedback may actually be perceived as an expression of surveillance, with all the negative results ensuing, including diminished creativity. At the same time, as shown by the researchers, negative feedback can serve as a stimulant to better performance by well-defined categories of contributors to the crowdsourcing platforms. The companies that increasingly seek ideas on their crowdsourcing platforms may take heed as the authors discuss how to stimulate creativity in the full light of their findings. The key to the long-term success of social commerce platforms is user engagement. What platform features foster it? This is the research question posed in the next paper, by Xiayu Chen, Zhaoyang Liu, Shaobo Wei, and Yezheng Liu. Drilling down, the authors’ empirics aim to answer the question, What platform affordances, classified as utilitarian, hedonic, and connective, support users’ sense of the platform and social identities, which in turn promote the engagement with the platform? The model offered and tested here is theory based and leads to normative advice to the platform offerors with respect to supporting different groups of their users as participants in the social commerce enterprise, rather than merely shoppers. The dark side of online lives has become an important area of research, simply because it has been increasingly affecting the lives of all of us. One of the phenomena on the dark side is the “collaborative” online attacks on brands, known as firestorms. There are numerous examples of such behavior and of its detrimental effects on the affected companies. Clearly, high-running user emotions are involved, but their nature had not been investigated. Here, we present such an investigation. Elena DelgadoBallester, Inés LópezLópez, and Alicia Bernal-Palazón study empirically the role of sadness, anger, and dislike in initiating an online firestorm. The appraisal theory of emotions serves as the foundation of the work. The nuanced findings help us both understand and—one hopes—contend with this revenge phenomenon.

We adopt a novel perspective in the analysis by drawing on the appraisal theory of emotions to dig in the emotional nature of the phenomena. Specifically, our research analyzes the role of three specific negative brand emotions (sadness, dislike, and anger) in a model that encapsulates cognitive, emotional, and motivational drivers of the initiation of an OF. The findings obtained from a sample of 303 individuals exposed to a brand misconduct episode suggest that openly expressed feelings of anger, dislike, and sadness emerge in response to outrage appraisals associated to the episode. However, only anger and dislike provided the impetus for taking revenge on the brand in the form of an OF. These findings contribute to a better understanding of the phenomenon since the role of emotions as a basis for explaining the act of initiating an OF has been overlooked. To practitioners, we offer some guidelines to monitor and manage the negative emotional content posted by individuals as mitigating them reduces the desire for revenge, which is the force behind their intentions to foster an OF.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"313 - 337"},"PeriodicalIF":5.0,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47868143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While digital feedback is the main, if not the only, two-way channel of communication between the platforms and the crowdworkers, little is yet known about how to use digital feedback to manage and foster the creative performance of crowdworkers. This study examines how the provision and nature of feedback, provided virtually through online interfaces, influence creative performance. We argue that the alleged positive relationship between the creative self-efficacy of crowdworkers and creative performance is conditional upon the joint effect of digital feedback valence and the degree to which crowdworkers focus on learning as achievement outcomes. We conducted a two-stage experimental study with 298 participants in a crowdsourcing setting. The results show that feedback provided in virtual settings, irrespective of whether the feedback is positive or negative, can be perceived as surveillance and thus hurt the creative performance of crowdworkers with high creative self-efficacy but low mastery goal orientation. However, the results also show that when receiving negative feedback, community members who have high creative self-efficacy and mastery goal orientation try harder in subsequent creative tasks. Accordingly, we advocate for nurturing platform cultures that emphasize both confidence in the contributor’s own competence and the abilities to learn and develop.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"263 - 286"},"PeriodicalIF":5.0,"publicationDate":"2021-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10864415.2021.1942674","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46196717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent research in this area draws on dual-system theory and demonstrates that while habit predicts use, it does not directly predict addiction-like symptoms. This is not surprising, since habit lacks valence and its measurement does not discriminate between desirable and undesirable use. To clarify the antecedents of addiction-like symptoms, this paper extends prior research by drawing on the dualistic theory of passions and argues that habit is a manifestation of harmonious and obsessive passions that are anchored in the user’s identity. By applying structural equation modeling on survey responses from 225 U.S.-based users, we first replicate and confirm the main findings of prior studies and then proceed to show that harmonious and obsessive passion drive Facebook habit and use. Moreover, obsessive passion emerges as the exclusive driver of addiction-like Facebook symptoms while the restraining effect of self-control is mediated by the two passions, as well as habit and use. The main finding is that the dual-system explaining Facebook addiction-like symptoms comprises of obsessive passion as the direct driving force and self-control as the indirect preventative restraining force. Our analysis contributes to the debate about mitigating the negative effects of social media and opens up new questions for further research.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"181 - 203"},"PeriodicalIF":5.0,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10864415.2021.1887697","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43685985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individuals often attempt to reduce their problematic use, but some may not be successful. This implies that there are both impeding and maintaining factors influencing problematic use and that different individuals may follow different mechanisms during problematic use. Drawing on cognitive dissonance theory and regulatory focus theory, our study develops a theoretical model to describe how impeding factors (here, injunctive norms) and maintaining factors (neutralization) influence individuals’ intention to reduce problematic use through guilt, as well as how the effects of these factors are moderated by individuals’ regulatory focus. The results provide strong support for our model. While injunctive norms have a stronger effect on prevention-focused users, the effect of neutralization is stronger on promotion-focused users. Our study highlights the importance of regulatory focus to our understanding of the differential impact of injunctive norms and neutralization and suggests that future studies further examine how individuals experience cognitive dissonance following different mechanisms. Our results suggest that when trying to reduce students’ problematic social media use, teachers need to follow different approaches for individuals with different types of regulatory focus.","PeriodicalId":13928,"journal":{"name":"International Journal of Electronic Commerce","volume":"25 1","pages":"204 - 229"},"PeriodicalIF":5.0,"publicationDate":"2021-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10864415.2021.1887698","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43229394","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
