Generation Z's (gen z) sharing of personal information on social media is a growing phenomenon with significant ramifications. Existing research, however, focuses on examining the role of social and/or psychological factors and fails to consider how and when social, psychological, and organizational factors affect gen z's willingness to share personal information on social media. To fill this gap, we propose a conceptual model based on the tenets of sociometer theory, to understand the dynamics of gen z's willingness to share personal information while considering its process and boundary conditions. Using a sequential multi-study design, we conducted an experiment followed by a survey to test our hypotheses using data collected from gen z in India. Our findings show that when gen z feels socially isolated/anxious, they are more likely to share personal information on social media. The effect of social isolation on sharing of personal information increases when gen z fear that they are missing out on the rewarding experiences others are having, are engaged in repetitive negative thoughts and perceive their firm's privacy policy as transparent and ethical. Our findings provide a better understanding of why, how, and when gen z's are willing to share personal information on social media. We extend existing limited research on the psychological aspects of digital natives' interaction with modern technologies. Our results equip social media marketing and brand managers with the knowledge they need to increase gen z's willingness to share personal information.  相似文献

Consumer education on food handling behavior is regarded as an effective method to improve domestic food safety and prevent foodborne illness, but is usually overlooked in rural areas. Using a presurvey and two rounds of postsurveys targeted at rural consumers from China included in a randomized controlled trial, this study investigated the effectiveness of two information interventions—a leaflet with tips for best practices and the leaflet plus consumer education sessions conveyed by phone—and compared them with a control group. Cloth use behavior was the target in the trial and five specific aspects were evaluated: (1) whether the cloth was made of old clothes, (2) whether the one used to clean kitchen tables was also used to wash dishes, (3) whether it was hung to dry, (4) how it was disinfected, and (5) how long the cloth was used before being discarded. Firstly, consumers' behavior was scored by summing the above-mentioned five behaviors. The results estimated using the difference-in-difference model showed that respondents in the leaflet-only group improved to a greater extent than those in the control group, but their difference in progress was not statistically significant until the second round of the postsurvey. Respondents in the leaflet-plus-phone group were quicker to adopt suggested practices and made discernible improvements compared with those in the leaflet-only group in the first round of the postsurvey, but the gap between these groups narrowed to statistically insignificant in the second round of the postsurvey. It was concluded that one consumer education session was effective and made a difference in the long term, whereas more education sessions produced normative behavior at faster rates, showing a significant improvement in the short term. Then, the study estimated the effectiveness of interventions on the five specific behaviors separately. The results were estimated using a probit difference-in-difference model and showed that the suggested behaviors with lower costs or a greater difference from past behaviors were more likely to be adopted by consumers. Consumer education facilitates proper food handling practices among rural households, which should be considered by policy makers.  相似文献

无论从对自然环境的破坏程度还是污染程度来讲,农业都不亚于工业,在一些方面甚至超过工业,因此,治理农业污染,推行清洁生产,不仅是必要的,而且势在必行。在农业清洁生产过程中存在不完全信息的情况,这使生产者和消费者产生逆向选择,最终影响到农业清洁生产的发展。文章试图用信息经济学的理论分析农业清洁生产中的不完全信息问题,并提出了解决的建议。  相似文献

融入新兴产业实现信息产业的转型,是广西经济建设的内在需要,也是顺应世界发展潮流的明智之举。本文对广西信息产业转型发展的可行性、难点及其突破思路进行分析。广西信息产业具备一定的规模,传统工业体系健全、相对发达,这为信息产业的转型奠定了基础;市场需求旺盛、关键技术得以突破以及广西与东盟有良好的信息产业合作平台,则为培育和发展新一代信息产业创造了条件。但是,与此同时,也面临人才匮乏,资金短缺,基础设施滞后以及政策执行不力等诸多难题,必须积极采取有效措施将其一一破解。  相似文献

As the amount of information is rapidly growing, and ubiquitous urban environments are emerging, the question which kind of information to provide is a major challenge for commercial and public travel-information service providers alike. This paper reports the analyses of recent data, collected in Metropolitan Seoul, about the acquisition of travel information. The study applies CHAID analysis to find homogeneous segments in travel information acquisition. Findings indicate that contextual variables are crucial to explain information acquisition behaviour, depending on decision context. The implication is that both socioeconomic and contextual variables are important to better understand the acquisition (and provision) of travel information. The results have important implications for managers and policy-makers, in particular in the way they respond to dynamic, contextual market segmentation.  相似文献

文章采用双边贸易引力模型,基于三个细分电子信息业的数据对国外专利权保护与中国出口之间的关系进行了实证研究。结果发现,总体上,国外专利权保护会通过市场扩张效应促进中国电子信息业出口,但这种积极的贸易效应主要存在于经济发达或模仿能力强的进口国,而在欠发达或模仿能力弱的进口国,专利权保护则通过市场势力效应对中国电子信息业出口产生消极影响。另外,国外专利权保护对中国电子信息业出口的贸易效应会随时间发展而趋于明显。  相似文献
