Exploring Older Adults' Adoption of We Chat Pay: A Cognitive Lock-In Perspective

Mobile payment has become increasingly popular worldwide, especially during the COVID-19 pandemic. However, older adults have more difficulties in adapting to mobile payments than others. To understand the reasons behind this phenomenon, we explore cognitive lock-in and its antecedents in adopting WeChat Pay based on the status quo bias theory. We use the PLS-SEM technique with survey data from Chinese older adults over the age of 50. The results show that the cognitive lock-in of older adults is significantly affected by technology anxiety, habit, regret avoidance, and uncertainty costs. Moreover, older adults' intention to adopt WeChat Pay is positively associated with social influence and self-actualization, while cognitive lock-in is a significant negative determinant. This study can help us better understand the underlying mechanism behind older adults' adoption of mobile payment from a cognitive lock-in perspective. Furthermore, this study steers the discussion about improving older adults' digital literacy and optimizing age-appropriate services for mobile payments.

A Multi-Dimensional Nomological Network of Mobile Payment Continuance

Despite the high utilization of mobile payment during the COVID-19 pandemic, this situation may change in the post-pandemic era. Therefore, great value can be derived from determining the significant antecedents of mobile payment continuance intention. This study looks to do so by introducing a Multi-Dimensional Nomological Network of Mobile Payment Continuance. A two-stage Partial Least Square-Structural Equation Modeling and Artificial Neural Network was utilized for the data analysis. The results provided empirical support to establish the overall nomological network. In addition, more than 70% of the variance in continuance intention was captured. Overall, this study provides practitioners with detailed insights to develop strategies for sustainable utilization and academics with a dynamic framework to look into users' mobile payment continuance intention.

Nudging COVID-19 Vaccine Uptake by Changing the Default: A Randomized Controlled Trial.

BACKGROUND: Although vaccination against SARS-CoV-2 is considered the central strategy against the pandemic, uptake lags behind target rates. METHOD: To explore whether this rate could be enhanced by a nudging strategy that exploits the status quo bias, we conducted a randomized controlled trial in northern Italy comparing vaccination acceptance among 2000 adults, ages 50 to 59 years, who were either invited to set an appointment (opt-in group) or assigned an individual appointment (opt-out group). RESULTS: Results indicate a difference of 3.2 percentage points, which represents a 32% relative increase in the vaccination rate for the opt-out group compared with the opt-in group. CONCLUSIONS: A significant portion of those who remain unvaccinated may not hold strong beliefs against vaccination but rather tend to inaction and may therefore be nudged toward vaccination with a reduction of action required. HIGHLIGHTS: Reluctant adults (50-59 years), who had not yet received vaccines against COVID-19, were sent letters announcing appointment availabilityIn an RCT, the status quo option in the notices influenced the rate of vaccine acceptanceNudging via pre-scheduled appointments encouraged vaccine uptake more than invitations to schedule didSwitching the default option yielded a 32% relative increase (13.1% vs. 9.9%) in vaccination.

Addressing threats like Covid: why we will tend to over-react and how we can do better

A number of behavioral economic insights suggest we will tend to overreact, individually and collectively, to a new, serious, but low probability health threat, like Covid 19. To respond more effectively to such threats, we should recognize why we will tend to overreact and prepare in advance not to do so. We also should recognize the usefulness in giving lower level governments, non-profits, and less formal communities some ability to respond, rather than presuming we should address a significant threat like Covid using the highest level of government.

COVID-19 Vaccine Passport and International Traveling: The Combined Effect of Two Nudges on Americans' Support for the Pass.

Immunity passports have the potential to allow large-scale international traveling to resume. However, they can only become an effective tool if they are widely supported by the general public. We carry out a double blind randomized online experiment with a sample of N=4000 Americans to study (i) whether two nudges can increase the level of support for a COVID pass for international traveling, (ii) the relationship between the effects of the nudges, and (iii) if these nudges have a negative spillover on the intention to get vaccinated. We find that both nudges increase the support for the COVID pass and that their impact is stronger when they are used together. Moreover, we find that the two nudges do not negatively affect intentions to get vaccinated. Our findings have important implications for policymakers and for the nascent literature on the interaction between multiple nudges.
