Ecosystem firms have been dominantly implementing knowledge sharing and collaboration between consumer interest groups, business firms and technology platform vendors (Adner, 2016). The ecosystem businesses create new value through business activity arrangements and individual offerings of the shared assets, standards, and interfaces upon a technology platform (Adner, 2006). Face with the highly dynamic and competitive environment, the multisided ecosystem platform firms specifically design mobile app to generate more participation in co-creation of value (Roma & Vasi, 2019). Little research has been dedicated for mobile app developers to understand user’s context-centric and user’s personalistic-centric mobility to formulate diversification or specialization in the cocreation strategic process. Our work focuses on the ecosystem users and customers as focal stakeholders who experiencing the peer-to-peer ecosystem platforms via mobile application could perceive context-centric and personalistic-centric mobility to fit, to make identification, to cocreate value, and to contribute to the ecosystem by their equity.

The study seeks to evaluate the impacts of three types of credit – formal, semi-formal, and informal credits – on the well-being of households in Vietnam’s rural areas. Based on data from the Vietnam Household Living Standard Surveys in 2014 and 2016, the research uses the instrumental variable fixed-effect models to estimate the effects of three kinds of credit on household’s per capita income and expenditure. There are some significant findings. First, in rural areas, formal credit is the most popular source with stable and cheap borrowing costs. Informal credit is a complement to formal credit to meet urgent needs. Funding agriculture activities is the most commonly cited purpose of borrowing, followed by purchasing assets. The highest misuse rate belongs to the group of loans for agriculture production. Second, the results show that credit helps smoothen consumption rather than generate income for rural households. Three types of credit have insignificant or negative effects on household’s per capita income. Formal loans significantly improve total expenditure and spending on healthcare and education. Informal and semi-formal credits show a little influence on consumption. Informal loans have a significantly positive effect on healthcare expenditure. In contrast, having semi-formal loans tends to decrease spending on foods.

This study was conducted to examine how independent audit firms in Vietnam understand and use risk based audit approach (RBAA) in audit practice. To answer the research questions, the researchers used primary and secondary data collected from 2018 to 2019. The results from the interview survey showed that audit firms were aware of the advantages of adopting RBAA. However, RBAA is practiced to a moderate extent by audit firms in Vietnam. Big 4 audit firms use RBAA more popularly than Non-Big 4 audit firms. The causes of the difference are the disadvantages of adopting RBAA and client’s characteristics such as relevant guideline, audit fees, auditors’ knowledge and experience. Besides, the study investigated factors impacting on the RBAA adoption by distributing a questionnaire to 246 auditors of 126 audit firms in Vietnam. A set of statistical appropriate methods where used through SPSS software version 22.0. The results indicated that there were six factors influencing RBAA adoption including: Auditor’s ability, Technological development, Audit fees, auditors’ motivation, Audit time and client’s risk. Of which, auditor’s ability and technological development are factors that have the most significant and positive impacts on the adoption of RBAA. Additional implications were argued in the final section of this study.
