The literature has demonstrated that lump-sum (LS) outperforms dollar-cost averaging (DCA) in uptrend markets while DCA outperforms LS only when the asset price is mean-reverted or downtrend. To bridge the gap in the literature, this study aims to use both Sharpe ratio (SR) and economic performance measure (EPM) to compare the performance of DCA and LS under both accumulative and disaccumulative approaches when the asset price is simulated to be uptrend.

This study uses both disaccumulative and accumulative approaches to compare DCA with LS and uses both SR and EPM to evaluate their performance when the asset price is simulated to be uptrend. Instead of using the annualized returns that are commonly used by other DCA studies, we compute the holding-period returns in the comparison in this paper.

The simulation shows that no matter which approach is used, DCA outperforms LS in nearly all the cases in the less uptrend markets while DCA still performs better than LS in many cases of the uptrend markets, especially when the market is more volatile and investment horizon is long, regardless which approach the authors used. The authors also find more evidence supporting DCA over LS by using EPM, which is more suitable in the analysis because the returns generated by DCA are positive skewed and flat-tailed that are ignored when SR is used.

The authors conclude that DCA is a better trading strategy than LS for investment even in the uptrend market, especially on high risky assets.

Investors could consider choosing DCA instead of LS as their trading strategy, especially when they prefer long term investment and investing in high-risk assets.

Fund managers could consider recommending DCA to their customers, especially when they prefer long term investment and investing in high-risk assets.

This is the own study and, as far as the authors know, this is the first study in the literature uses both SR and EPM to compare the performance of DCA and LS under both accumulative and disaccumulative approaches when the asset price is simulated to be uptrend.

This paper aims to investigate the nonlinear relationship between corporate social performance (CSP) and economic policy uncertainty (EPU).

This paper uses panel regression techniques to examine a sample consisting of UK-listed non-financial companies during 2000–2018.

The authors found that EPU increases corporate social responsibility which suggests that firms become more socially proactive during the period of heightened EPU. Such countermeasure enhances CSP and is likely a part of a competitive strategy and an insurance mechanism to protect firms against uncertainty in long-term. Further analysis shows a nonlinear relationship between the two factors, suggesting that in a heightened uncertain business environment, the insurance benefit generated by CSP is neutralised by the corresponding cost and, therefore, the positive relationship between EPU and CSP reverses.

This paper is the first to find a nonlinear relationship between CSP and EPU, indicating that too much uncertainty in macroeconomic policies deteriorates the benefits of CSP to the point that the CSP – EPU relationship becomes negative. The results suggest that policy uncertainty has both the bright side and the dark side where too many cooks eventually spoil the broth.

Innovation is ever more critical for sustainable business performance in the contemporary, global economic and social context. Small- and medium-sized enterprises (SMEs) are arguably well positioned to innovate through their potential for rapid adjustment. Although leadership and organizational climate have been identified as playing a key role in innovation, little is known about whether such influences play out in SMEs. The aim of this study is to explore how leaders shape the organizational climate of their firms to enhance innovation.

The article presents findings from semi-structured interviews conducted with 20 CEOs of SMEs in the Vietnamese tourism sector.

The findings indicate that SME leaders in the tourism sector influenced an organizational climate that provided for autonomy and supported innovation through a number of leadership approaches. They also used daily interaction-based practices to drive the innovative behaviors of employees and developed reward systems to encourage innovation in their organizations.

This study explored leaders' approaches toward developing an organizational climate to stimulate innovation in tourism SMEs. Where leaders share frequent communication and knowledge with their subordinates, they perceive a climate for innovation developments, which stimulates innovation in tourism SMEs.

The study provides implications for managers to improve creativity and innovation in firms through the development of reward and incentive systems along with leadership and team development programs.

This study describes how different leader approaches affect innovation through orientating the organizational climate and business processes within their firms toward encouraging staff to initiate and try out new ideas.

Intellectual capital, corporate governance (CG) and corporate social responsibility (CSR) are generally considered three essential pillars to enhance firms’ performance in the developed world. However, in developing countries such as Vietnam, these pillars have not received sufficient attention from practitioners. In addition, this study aims to investigate the interrelationship between these three essential pillars and their combined effects, in the Vietnamese context.

This study uses data collected from the annual reports of the largest listed banks in Vietnam from 2011 to 2018. Intellectual capital is measured using a modified value-added intellectual coefficient model. CG is proxied by board remuneration. This study measures CSR using the ratio between charitable contributions and profit before tax. In addition, this study uses the generalized method of moments to overcome several econometric problems exhibited in previous empirical studies.

Results indicate that CG and CSR have a positive impact on intellectual capital. Intellectual capital plays a moderating role in the relationship between CG and CSR. Moreover, CG and intellectual capital in the previous year significantly affect CG in the current year.

Based on the findings from this study, policy implications have emerged for bank executives and policymakers in formulating and implementing policy about the balance between intellectual capital accumulation, CG and CSR.

To the best of the authors’ knowledge, this is the first empirical study conducted to examine the interrelationship between intellectual capital, CG and CSR and their combined effects in emerging countries such as Vietnam.

The purpose of this paper is to review both international and domestic (i.e. Vietnamese language) journal articles and graduate theses and dissertations on educational leadership in Vietnam. The review addresses two specific goals: first, to describe and critically assess the nature of the formal knowledge base on principal leadership in Vietnam, second, to synthesize findings from the existing literature on principal leadership in Vietnam.

The paper employed a method for conducting systematic reviews of research. The authors conducted a detailed, exhaustive search for international and “local” papers from Vietnam, yielding 120 research sources. Information from these papers was extracted and evaluated prior to analysis. Data analysis included both quantitative description of the “review database” as well as critical synthesis of substantive findings.

The review supports and extends an earlier review which found that the practice of educational leadership in Vietnam remains largely “invisible” to the international community of scholars. The review also yielded a highly critical assessment of research perspectives and methods used in the “local” Vietnamese studies which comprised the bulk of the authors’ database. Synthesis of substantive findings highlighted the manner by which organizational, political, and socio-cultural forces in the Vietnamese context shapes the practice of school leadership.

First, qualitative studies are recommended that seek to describe, in-depth, the enactment of leadership in the Vietnamese context. Second, broad-scale surveys of characteristics, attitudes, and beliefs of school leaders across Vietnam are warranted. Third, the authors encourage graduate students and scholars studying school leadership in Vietnam to undertake a new generation of theory-informed studies that connect with the global literature.

Due to the relatively weak nature of the existing knowledge base, the authors were unable to identify specific implications for leadership practice. However, practical implications are identified for developing the research capacity needed to improve research quality in Vietnam’s universities.

This review is the first systematic review of educational leadership and management conducted of the Vietnamese literature. Moreover, the authors suggest that the review is original in its comprehensive coverage of both the local and international literature on educational leadership in Vietnam.

COVID-19 hits every country’s health-care system and economy. There is a trend toward using automation technology in response to the COVID-19 crisis not only in developed countries but also in those with lower levels of technology development. However, current studies mainly focus on the world level, and only a few ones report deployments at the country level. The purpose of this paper is to investigate the use of automation solutions in Vietnam with locally available materials mainly in the first wave from January to July 2020.

The authors collected COVID-related automation solutions during the first wave of COVID-19 in Vietnam from January to July 2020 through a search process. The analysis and insights of a panel consisting of various disciplines (i.e. academia, health care, government, entrepreneur and media) aim at providing a clear picture of how and to what extent these solutions have been deployed.

The authors found seven groups of solutions from low to high research and development (R&D) levels deployed across the country with various funding sources. Low R&D solutions were widely spread owing to simplicity and affordability. High R&D solutions were mainly deployed in big cities. Most of the solutions were deployed during the first phases when international supply chains were limited with a significant contribution of the media. Higher R&D solutions have opportunities to be deployed in the reopening phase. However, challenges can be listed as limited interdisciplinary research teams, market demand, the local supporting industry, end-user validation and social-ethical issues.

To the authors’ best knowledge, this is the first study analyzing the use of automation technology in response to COVID-19 in Vietnam and also in a country in Southeast Asia. Lessons learned from these current deployments are useful for future emerging infectious diseases. The reality of Vietnam’s automation solutions in response to COVID-19 might be a reference for other developing countries with similar social-economic circumstances and contributes to the global picture of how different countries adopt technology to combat COVID-19.

The paper aims to examine the impact of tighter banking regulation on banks’ loan loss provisioning in an emerging market context.

The authors exploit the adoption of the Basel II Accord in Vietnam as a quasi-natural experiment and use Difference-to-Difference (DiD) method to examine the impact of tighter banking regulation on Vietnamese banks’ provisioning during the period of 2010–2019.

The paper finds that affected banks (i.e. those taking part in the pilot adoption programme) manage to reduce their provisions significantly compared to their control peers in the post-adoption period. More importantly, this paper further finds that the affected banks manage their provisions primarily for incomes smoothing and signalling. This paper also finds that those banks expand their lending significantly and experience an increase in financial performance in the post-adoption period. Overall, the results provide supports for the “borrowing from the future” proposition that banks may perceive that a tighter banking regulation provides them with growth opportunities, so they have the tendency to manipulate their provisions to facilitate their current income.

This paper contributes to the established literature on the manipulation of bank provisioning as well as the impact of banking regulation, and especially Basel II on bank economic decisions. As compared to prior literature, the adoption of Basel II in Vietnam provided an ideal shock for us to conduct a DiD design to estimate the causal impact of tighter banking regulation on banks’ provisioning practices.

The purpose of this paper is to investigate the effects of empowering leadership, directive leadership and initiating structure on innovation in small and medium enterprises (SMEs) and examine the mediating role of climate for innovation on those relationships.

Applying structural equation modeling, the study empirically tested the model on a sample of 330 employees from tourism SMEs in Vietnam.

Results indicated that climate for innovation mediated the relationship between empowering leadership and innovation and also initiating structure and innovation. Whereas empowering leadership was found to have a negative direct influence on innovation, directive leadership was unrelated to innovation.

The results of this study contribute to the literature by expanding the existing research on SME innovation, assessing the effect of diverse leadership styles and a climate for innovation on the innovation performance of SMEs. The findings enrich the literature by indicating the contribution of empowering leadership, directive leadership and initiating structure on encouraging innovation in SMEs.

When leading subordinates in the SME context, leaders who have a clear understanding of the effect of empowerment, direction and initiating structure can optimally seek to stimulate innovation. These leadership approaches influence employees’ task, interpersonal and role-related processes that shape a climate for innovation.

The novelty of this paper is that it examines the differential influences of empowering leadership, directive leadership and initiating structure on innovation and the mediating role of climate for innovation on these relationships.

The purpose of this paper is to estimate a recent trend in climate change and its impact on livelihood of community living in Nam Dinh province, Vietnam. Further, it aims to increase the government attention for adaptation measures by providing awareness of climate change and its negative impacts on livelihood.

For study purpose, cross-sectional and secondary data sets were used. The community perceptions about climate change were recorded by face-to-face interviews of 500 respondents from Nam Dinh province, Vietnam in April 2015 by using a well-structured questionnaire, whereas secondary data were collected from the statistical yearbook of General Statistics Office of Vietnam. To accomplish the study objectives, Cobb–Douglas production function and Likert scale were used to estimate the community perceptions of climate change and impact of climate change on livelihood, respectively.

Results depict that climate change negatively impacted on the productivity of rice and livestock. Particularly, frequently occurring of droughts, floods and salinity intrusion negatively impacted on rice productivity, while livestock productivity is decreased by frequent occurring of flood storms in study area.

The study results suggest a government support is essential to achieve sustainable livelihoods for coastal communities living in the Red River Delta, particularly some adaptation measures in the context of climate change are required in study area.
