Interplay between subjective norm, emotions, and purchase intention towards foreign brands: Evidence from Vietnam

Indonesia is a country with the largest Muslim population in the world. However, since the Islamic banks were being established in Indonesia for about 20 years, their market share only accounts for about 5% in the Indonesian banking system. Muslim participations in using Islamic bank are relatively low. This study expands the Theory of Planned Behavior by adding the variables of religiosity and self-efficacy. Previous studies have not examined this new expanded model to analyze customers who participated in using the saving Islamic bank’s products and services. Based on 220 Islamic bank consumers who participated in the study, the study indicated that questionnaires about religiosity and self-efficacy had good external validity and could be adapted for the Indonesian culture context. The most interesting finding was that the religiosity variable strongly enhanced the use of Islamic banks. Similarly, this study found that the self-efficacy variable improved an intention of customers to participate in the Islamic banking system. This paper also discusses the implications of the findings and recommendations for future studies.

The paper investigates the impact of institutional quality on economic growth by taking 48 countries in Asia between 2005 and 2018. By using the quantile regression methods with panel data, institutional quality is found to be a key factor of economic development. However, in the lower-income Asian countries, the institution with better quality appears to promote the growth more effectively than in the higher-income ones. Moreover, the paper also finds out a nonlinear relationship between institutions and economic growth. The results show that there is an institutional threshold for economic growth to reach its highest level. If the institution indicator exceeds the threshold, it causes the reverse effect on the growth. Moreover, the economic growth of Asian countries is also affected by inflation (INF), labor force (LABO), trade openness (OPEN), and infrastructure (TELE). From that, the study suggests some policy implications for Asian countries and Vietnam, in particular, in order to improve institutions contributing to economic growth.

This study examined the impact of social commerce on the purchase intentions of Millennials who use Facebook by exploring how social commerce constructs influence consumer trust. A quantitative research approach was used and data were collected via an ‘online’ survey. The target population was 386 young adults aged 25 to 34 residing in KwaZulu-Natal, South Africa, referred to as Millennials, and comprises the largest group of users on Facebook. Convenience sampling, namely snowball sampling, was used to target participants. It was found that social commerce constructs significantly influence trust, which positively influences consumer purchasing decisions. The results of the study showed that trust explained 68% of the variance in purchasing intentions. Since trust is an integral and vital component of social commerce, the role of social commerce constructs and social support is to build trust in the ‘online’ context and consumers’ intention to buy. This suggests that businesses should monitor the quality and content of the engagements around their brands on social media, as information sharing in social commerce has a significant impact on consumer decisions, i.e., purchase intentions.
