The goal of the study is to offer important insights into the dynamics of the cryptocurrency market by analyzing pricing data for Bitcoin. Using quantitative analytic methods, the study makes use of a Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model and an Autoregressive Integrated Moving Average (ARIMA). The study looks at how predictable Bitcoin price swings and market volatility will be between 2021 and 2023.

The data used in this study are the daily closing prices of Bitcoin from Jan 17th, 2021 to Dec 17th, 2023, which corresponds to a total of 1065 observations. The estimation process is run using 3 years of data (2021–2023), while the remaining (Jan 1st 2024 to Jan 17th 2024) is used for forecasting. The ARIMA-GARCH method is a robust framework for forecasting time series data with non-seasonal components. The model was selected based on the Akaike Information Criteria corrected (AICc) minimum values and maximum log-likelihood. Model adequacy was checked using plots of residuals and the Ljung–Box test.

Using the Box–Jenkins method, various AR and MA lags were tested to determine the most optimal lags. ARIMA (12,1,12) is the most appropriate model obtained from the various models using AIC. As financial time series, such as Bitcoin returns, can be volatile, an attempt is made to model this volatility using GARCH (1,1).

The study used partially processed secondary data to fit for time series analysis using the ARIMA (12,1,12)-GARCH(1,1) model and hence reliable and conclusive results.

The purpose of this research is to advance the conceptual and practitioner understanding concerning the maximisation of Industry 4.0 technologies industries in an emerging economy. The study first examines the internal resources that companies possess to implement Industry 4.0 effectively and, second, identifies the critical gaps that necessitate external resources, both at the industry and government levels.

The study embraces qualitative and inductive approaches with semi-structured interviews conducted with 112 company leaders representing nine industries and operating in various cities/regions of Vietnam.

The data analysis helped unveil 16 critical dimensions. Notably, the organisation-developed competences dimension illuminates the understanding regarding firms’ available internal resources, while the financial management and technological leap ability dimensions help explain firms’ required resources. More broadly, the business community unity and business community learning dimensions ascertain the significance of industry-level support, while the technological sponsorship and legal framework guide dimensions underline government support.

First, the study unpacks various key aspects of their daily, mid- and long-term operations associated with their current internal resources, gaps identified and the support they require to progress within the Industry 4.0 environment. Second, the study proposes a framework that advances the extant conceptual understanding of operational, strategic, managerial and production aspects among firms operating in an emerging economy. Third, it focuses on companies operating in nine industries in an emerging economy. Fourth, the study contributes to addressing various extant research gaps.

The purpose of this study is to examine the implementation of Industry 4.0 (I4.0) through the lens of the dynamic capabilities framework. Contrary to most existing research, this study chooses a cross-national viewpoint, exploring companies operating in two emerging economies.

Semi-structured interviews were conducted with 80 company managers operating in eight industries in Vietnam and Bolivia. The chosen inductive analysis was supported by qualitative content analysis and data structure.

The analysis reveals 13 conceptual dimensions. For instance, sensing opportunities underlines tangible and intangible “direct prospects”, such as enhanced accuracy, speed and cost effectiveness, whereas “operational management pressures” (sensing threats) identify the dilemma of changing individuals’ mindset, recruitment and addressing financial needs. While there is an overall agreement in key dimensions, differences between managers from both countries also arise, including staff’s adaptation and constant upskilling.

Empirically, this study responds to calls for cross-national studies investigating I4.0 initiatives. In doing so, the data gathered from company managers engaged in business in emerging economies afford new perspectives, with practitioner value. Theoretically, the numerous dimensions emerging from the data analysis provide useful conceptual insights to understand managerial aspects in considering and adapting to I4.0 expectations and requirements. These insights are reinforced by the development of a conceptual model that illuminates the initiatives, efforts and challenges of embracing this phenomenon.

This article aims to study the nonlinear effect of financial inclusion on tax revenue of 21 low financial development countries (LFDCs) and 22 high financial development countries (HFDCs) from 2004 to 2020.

The study calculates the world average financial development index (FD̅) for all countries using data from the IMF. The average FD of HFDCs is higher than (FD̅). On the other hand, the average FD of LFDCs is lower than (FD̅). Data of 21 LFDCs and 22 HFDCs cover the period 2004–2020. With the small sample problem, we applied the Bayesian method to examine the nonlinear effect of financial inclusion on the tax revenue of the two groups of countries.

Using the Bayesian method, the results show that financial inclusion negatively impacts tax revenue with an absolute probability of 100% in LFDCs and a lower probability of 92.45% in HFDCs. Additionally, the financial inclusion threshold at LFDCs is 18.90. Below this threshold, financial inclusion promotes tax revenue with a 100% probability. On the contrary, when financial inclusion exceeds the threshold, it will have a negative effect on tax revenue. Similarly, the financial inclusion threshold at HFDCs is 20.14, with a probability of 92.45%.

To the best of the authors’ knowledge, this is the first paper to examine the nonlinear impact of financial inclusion on tax revenue in high and low financial development countries.

The purpose of the study is to enhance the extant empirical and conceptual understanding of Industry 4.0 (I4.0) adoption and its repercussions for an organisation operating in an emerging economy, considering the dynamic capabilities framework. The study investigates (1) the potential impact of the I4.0 phenomenon on relationships between organisations and industry actors, (2) the existing effects of I4.0 on these relationships and (3) the necessary measures for organisations to unlock the full potential of I4.0 in order to enhance and reinforce these relationships.

A qualitative method was used. Semi-structured, open-ended face-to-face and online interviews were conducted with 18 directors, managers and chief executive officers (CEOs) of Savico, a leading Vietnamese car dealership.

The analysis revealed various dimensions highlighting impacts on organisation–industry actor relationships. For instance, the “enhancing internal/external operations” dimension highlights the significance of benefitting the company’s close stakeholders through a centralised management system or more advanced functions, while the empowering-nimble outcomes dimension underlines the benefits of I4.0 in enabling performance-based choices and staff empowerment.

Technological phenomena such as the I4.0 regime require constant adaptive strategies, including knowledge acquisition and talent development. Thus, the study has implications for industry stakeholders, including companies, educational institutions and government agencies.

The study’s key value lies in proposing a model that provides conceptual depth into organisation–industry actor relationships. Furthermore, both the analysis and the model can guide researchers in future attempts to examine dynamic capabilities among firms operating in emerging economies, with important practical and theoretical implications.

The purpose of this study is to gain a more nuanced understanding of the relationship between a national product (coffee) and gastronomy. Moreover, incorporating the resource-based view of the firm framework, the importance of coffee is examined, as is the extent and potential to “marry” coffee and gastronomy into a tourism activity, and the need to develop such potential.

Semi-structured, face-to-face and online interviews were used to gather the viewpoints of 79 chefs and coffee shop owners/managers operating in Vietnam, the world’s second-largest coffee producer and home to a vibrant coffee shop industry.

The selected inductive analysis identified 11 dimensions, including “coffee infrastructure”, “coffee-based innovation”, “coffee-trigger” and “coffee resources”, emerged. These dimensions reveal a strong potential for a coffee and local gastronomy “marriage”. Furthermore, nine of the 11 dimensions provide direct guidance concerning the importance, the potential for “marriage”, coffee tourism development and what is needed to fulfil this potential.

The study affords understanding of Vietnam’s coffee industry, in particular its resources, and how these can be leveraged to combine with the nation’s gastronomy and produce more fulfilling food and beverage experiences.

Gastronomy, hospitality and tourism represent a well-defined partnership that can result in memorable consumer experiences. While the strength of this partnership is recognised, little is known about the potential to “marry” a national product such as coffee and local gastronomy. The study breaks new ground in this area and concludes with various theoretical and practical implications that contribute to more understanding of the coffee–gastronomy relationship.

The purpose of this study is to enhance the conceptual and practical understanding of individual, group and future knowledge as perceived by company owners and managers operating in Vietnam. To date, knowledge gaps remain concerning this emerging economy, for instance, regarding the significance of knowledge management (KM) skills and innovativeness in positively affecting firms' journey. Overall, the study will add to the extant KM literature, partly address extant research gaps and develop a conceptual model. To support the study's literature foundation, the knowledge-based view framework will be considered.

An inductive approach and multi-case study were chosen. The views of 17 individuals in leadership positions representing six companies were gathered through semi-structured, in-depth interviews.

The analysis revealed the influence of seven dimensions. First, the importance of individuals' knowledge is conceptualised by the conspicuous, approach-based and self-initiated dimensions. Second, the collective action-based and collective approach-based knowledge dimensions illuminate the importance of group knowledge. Third, the externally and internally-oriented knowledge dimensions provide guidance and understanding concerning future knowledge. The analysis also underlines the alignment between the findings and the knowledge-based view in various areas.

The dimensions illuminating the research have practical implications for business owners/managers, for instance, motivational and rewarding strategies that companies could consider in order to enhance or maintain a high flow of knowledge acquisition and operationalisation. Furthermore, these implications could help foster a stronger entrepreneurial culture and benefit Vietnam or other emerging economies in their development and success journey. Conceptually, a developed framework affords a richer understanding of the different facets of knowledge at a company level.

This study aims to investigate the trend of research on universities and accountability (UAA) in Southeast Asian (SEA) countries.

A total of 115 journal articles, conference papers, books and book chapters were obtained from the Scopus database spanning the years 1996–2023. These documents were subsequently analyzed using bibliometric methods.

The majority of UAA in SEA documents were published between 2007 and 2023 (106 documents, 92.19%). Scholars from both SEA countries and outside the region, particularly Australia, co-authored UAA in SEA documents. While scholars from Vietnam contributed the highest number of UAA in SEA publications (30 documents), scholars from Australia received the highest number of citations (878 citations). Collaboration between Vietnam and Australia emerged as the most productive partnership in conducting studies on UAA in SEA. Additionally, UAA in SEA documents were published not only in education-related outlets but also in other sectors, particularly in public policy. Furthermore, studies on UAA in different countries exhibited both similar and dissimilar interest keywords.

This study represents the first bibliometric analysis focusing on UAA in SEA literature. The insights and implications derived from this study are valuable for future researchers, university leaders and policymakers.

The purpose of this research is to explore the motivators and barriers faced by successful women entrepreneurs in Vietnam, a country with high rates of early-stage and established business ownership by women. By integrating the push-pull theory with macro, meso, and micro-level factors, this study provides a comprehensive overview of the factors influencing female entrepreneurship in this context.

The data for this exploratory qualitative study were collected through in-depth semi-structured interviews with 31 successful female entrepreneurs in Vietnam. The analysis was conducted using NVivo software, employing thematic analysis to identify the motivators and barriers associated with women’s entrepreneurship.

The findings indicate that women are motivated to start businesses by push factors like job dissatisfaction, economic improvement, and family support, as well as pull factors such as time flexibility, autonomy, and personal development. Barriers are identified at different levels: micro-level challenges include lack of financial support, inadequate skills, and work-life balance issues; meso-level barriers involve insufficient training programs, and macro-level barriers are shaped by gender prejudice. Notably, specific to the sectors, the lack of business training is a major challenge for women in consultancy, tourism, and retail sectors, alongside financial constraints in retail and services.

As a theoretical contribution, this study presents a novel model that integrates push/pull theory with macro, meso, and micro-level factors to analyze the motivators and barriers for female entrepreneurship. This integrated model offers a comprehensive view of women’s entrepreneurship in Vietnam’s transitional economy, enhancing understanding of their motivations and challenges, addressing existing gaps, and suggesting practical implications.

Over several decades, the Vietnamese government has gradually reduced funding for public higher education and has implemented a cost-sharing system. As a result, Vietnamese universities have had to look for alternative sources of income. While there is a significant emphasis on the importance of revenue diversification in higher education in Vietnam, there is limited empirical data on financing for Vietnamese higher education. The purpose of this paper, therefore, is to estimate the degree of financial sustainability in Vietnamese universities.

The authors used the Hirschman–Herfindahl Index and multiple regression analysis to assess 134 Vietnamese universities’ financial sustainability between 2013 and 2020.

The results revealed that almost all universities in this study were unsustainable due to their weak financial diversity. The age, type of ownership, location, the ratio of lecturers with PhD degrees and land size can affect the financial diversification level of higher education institutions. Our study highlighted that public universities have better financial health than private universities; institutions in rural areas have higher financial diversification than in big cities.

Suggestions for policymakers and university leaders that may enhance financial sustainability include the adoption of tailored strategies based on the university’s characteristics and missions.
