The purpose of this paper is to examine the effects of share repurchase announcements on the stock price of rival firms in the same industry in Vietnam during 2010–2017.
Abstract
Purpose
The purpose of this paper is to examine the effects of share repurchase announcements on the stock price of rival firms in the same industry in Vietnam during 2010–2017.
Design/methodology/approach
Both event study and t-test are employed to test the effects of share repurchase announcements on rival firms. In addition, cross-sectional analysis by ordinary least square regression is also applied for investigating the heterogeneous effects due to information transfer.
Findings
The finding shows that stock repurchase announcements result in a positive and significant valuation effect for both announcing firms and rival firms in Vietnam. Furthermore, the degree of signal to the industry is conditional on the degree of signal about the announcing firms as a contagious effect. Intra-industry effects are more favorable when profit performance of rival firms is good and when leverage of rival firms is low.
Practical implications
Rival firms can seize opportunities surrounding share repurchase announcements in the same industry in Vietnam. However, due to firm characteristics, intra-industry effects of stock repurchases differ among industries.
Originality/value
By examining different methods, the paper attributes valuable results to investigate the stock price behavior of rival firms in the same industry when firms announce stock repurchase in Vietnam.

Abstract
Purpose
This study investigates the relationship between credit booms and bank risk in Association of Southeast Asian Nations (ASEAN) countries, with credit information sharing acting as a moderator.
Design/methodology/approach
The authors use a two-step System Generalized Method of Moments (SGMM) estimator on a sample of 79 listed banks in 5 developing ASEAN countries: Indonesia, Philippines, Malaysia, Thailand and Vietnam in the period 2006–2019. In addition, the authors perform robustness tests with different proxies for credit booms and bank risk. The data are collected on an annual basis.
Findings
Bank risk is positively related to credit booms and is negatively associated with credit information sharing. Further, credit information sharing reduces the detrimental effect of credit booms on bank stability. The authors find that both public credit registries and private credit bureaus are effective in enhancing bank stability in ASEAN countries. These results are robust to regression models with alternative proxies for credit booms and bank risk.
Research limitations/implications
Banks in ASEAN countries tend to have strong lending growth to support the economy, but this could be detrimental to stability of the sector. Credit information sharing schemes should be encouraged because these schemes might enable growth of credit without compromising bank stability. Therefore, policymakers could promote private credit bureaus (PCB) and public credit registries (PCR) to realize their benefits. The authors' research focuses on developing ASEAN countries, but future research could provide more evidence by expanding this study to other emerging economies. In-depth interviews and surveys with bankers and regulatory bodies about these concerns could provide additional insights in the future.
Originality/value
The study is the first to examine the role of PCB and PCR in alleviating the negative impact of credit booms on bank risk. Furthermore, the authors use both accounting-based and market-based risk measures to provide a fuller view of the impact. Finally, there is little evidence on the link between credit booms, credit information sharing and bank risk in ASEAN, so the authors aim to fill this gap.

Abstract
Purpose
Shipping is a major source of air pollution, causing severe impacts on the environment and human health, greatly contributing to the creation of greenhouse gases and influencing climate change. The research was investigated to provide a better insight into the emission inventories in the Red River in Hanoi (Vietnam) that is often heavily occupied as the primary route for inner-city waterway traffic.
Design/methodology/approach
The total emissions of seven different pollutants (PM10, PM2.5, SOx, CO, CO2, NOx and HC) were estimated using the SPD-GIZ emission calculation model.
Findings
The results show that CO2 has the most significant contribution to the gas volume emitted: 103.21 tons/day. Remarkably, bulk carriers are the largest emission vehicle, accounting for more than 97% of total emissions, due to their superior number and large capacity.
Social implications
The result to have a roadmap for making efforts to fulfil its commitment so that it could achieve its net-zero climate target by 2050 in Vietnam as committed at COP26.
Originality/value
In this research, the number of vehicles and types of vessels travelling on the Red River flowing within Hanoi territory and other activity data are reported. The tally data will be used to estimate emissions of seven different pollutants (PM10, PM2.5, SOx, CO, CO2, NOx and HC) using a method combining both top-down and bottom-up approaches.

This study aims to investigate the interrelationships between charter value and market discipline in five Southeast Asian countries (ASEAN-5).
Abstract
Purpose
This study aims to investigate the interrelationships between charter value and market discipline in five Southeast Asian countries (ASEAN-5).
Design/methodology/approach
This research uses a simultaneous equations model with a three-stage least squares estimator for a sample of 79 listed banks from 2006 to 2019.
Findings
The findings show a negative two-way relationship between charter value and market discipline. More specifically, charter value can reduce market discipline. Meanwhile, a negative relationship between market discipline and charter value reemphasizes the significance of market discipline in the banking system to enhance bank charter value. Similar results still hold when using several robustness checks (e.g. subsamples, considering the global financial crisis, governance indicators and market structure).
Originality/value
To the best of the authors’ knowledge, this study is the first attempt to investigate the bidirectional relationship between bank risk and charter value in ASEAN-5. Therefore, this study would provide significant recommendations for policymakers and practitioners.

Abstract
Purpose
This study aims to present the results of a comparative study on the most key reasons for the failure of sustaining activities of operational improvement (OI) methodologies from the different types of manufacturing enterprises that located in Vietnam.
Design/methodology/approach
This study presents survey results from 30 local manufacturing enterprises and 21 foreign direct investment (FDI) enterprises located in Vietnam – a developing country. The authors utilize a combination method to collect data, including online and direct survey. The targeted interviewees selected to answer the questionnaire are manufacturing managers and top managers working in productivity, quality, engineering and other departments in respective firms. The developed questionnaire is verified by five experts to ensure the validity and soundness.
Findings
The study uncover that 21 local enterprises (70%) have not issued standard forms for OI deployment and supervision, while 17 foreign enterprises (81%) have adopted a systematic management and clearly indicators for evaluation of OI outputs. In addition, the top three reasons for OI failure are differences between local and foreign enterprises. In term of OI methodologies, most of participated enterprises implemented Lean tools and principles while only 7.8% of the participated enterprises applied Six Sigma. Three vital findings are uncovered, including, first, 30% of local enterprises standardize and supervise forms of OI.
Research limitations/implications
There is a limitation in sample size, with the number of participants of 51 enterprises. Among the participants, 27% of local enterprises are small and medium-sized enterprises (SMEs) while 60% of FDI enterprises from large-sized group. This was limited to making a generated conclusion in the comparison of failure factors between two types of enterprises. This partly affects the radical comparison of failure factors between local and FDI enterprises.
Originality/value
To the best of the authors' view, this is the first empirical study that compares the reasons for the failure for sustaining OI between local and foreign enterprises in a developing country. The result from this study will make contributions for further research in considering OI failure factors and then enhance effectiveness of OI methodologies in manufacturing companies.

This study aims to investigate whether the changes in gender composition of bank board affects Vietnamese bank stability efficiency.
Abstract
Purpose
This study aims to investigate whether the changes in gender composition of bank board affects Vietnamese bank stability efficiency.
Design/methodology/approach
This research covers a panel of 27 commercial banks in Vietnam over a 14-year period from 2007 to 2020. The two-step system generalized method of moments is used to estimate the gender diversity–Vietnamese bank stability efficiency nexus.
Findings
The authors find that a greater degree of board gender diversification enhances bank stability efficiency and reduces bank risk-taking in Vietnam. The relationship between gender diversity and the stability efficiency of Vietnamese banks is still valid under the influence of regulatory capital sufficiency and during the financial crisis. These findings are robust to alternative proxies for risk indicators and consistent with the perspectives of stakeholder and behavior theory.
Originality/value
Although this research revisits the relationship between gender diversity and bank risk-taking, it is the first attempt to explore the role of women on board in enhancing the stability efficiency of banks, using the stochastic frontier approach. These findings shed light on the function of gender diversity as a governance instrument for mitigating risk in an emerging market context.

Abstract
Purpose
The financial system has witnessed the substantial growth of financial technology (fintech) firms. One of the strategies that banks have adopted to cope with this emergence is to cooperate with fintech firms. This study empirically investigated whether cooperation between banks and fintech companies would improve banks’ risk-adjusted returns.
Design/methodology/approach
We developed a novel index of bank–fintech cooperation across various fintech sectors. A system generalized method of moments (GMM) was used to examine this relationship using a sample of Vietnamese banks from 2007 to 2019.
Findings
The findings show that the diversity of bank–fintech cooperation across seven sectors tends to enhance banks’ risk-adjusted returns. The results also highlight that this relationship may depend on the types of fintech sectors and bank ownership. More specifically, the positive association between this cooperation and banks’ risk-adjusted returns only holds in the comparison sector of fintech, whereas there is a negative relationship between them in the payments and mobile wallets sector. Furthermore, state-owned commercial banks that engage in more bank–fintech cooperation tend to generate greater earnings. If we look at listed banks, the positive effect of bank–fintech partnerships on risk-adjusted returns still holds. A similar result was also found in the case of large banks.
Practical implications
Our empirical evidence provides motivations for incumbent banks to implement appropriate strategies toward diversity in bank–fintech partnerships when fintech firms have engaged in various financial segments.
Originality/value
This study adds more evidence to the existing literature on the relationship between bank–fintech cooperation and bank performance.

This study aims to investigate the effect of digitalization on bank profitability among Vietnamese banks.
Abstract
Purpose
This study aims to investigate the effect of digitalization on bank profitability among Vietnamese banks.
Design/methodology/approach
The research employs fixed-effects regression on a panel data of 32 banks in Vietnam during the period 2010–2021.
Findings
The study reveals a positive impact of digitalization on bank profitability. The result is robust to different measures and empirical settings. Not surprisingly, small banks and banks with high percentage of state ownership experience lower profitability than their peers. However, digitalization helps improve the profitability of these banks. This study explains the effect by showing that digitalization significantly reduces bank cost in terms of cost to income ratio and increases bank non-interest income through diversification into non-traditional products and services. In addition, the current stage of bank digitalization in Vietnam does not reduce banks’ employment costs since it requires staffs to support and operate the new system.
Practical implications
The research findings are motivations for bankers and policy-makers in designing appropriate strategies toward digitalization. Investors can also consider highly digitalized banks as valuable investment.
Originality/value
This research extends the current literature on the relationship between digitalization and bank profitability, with a focus on commercial banks in Vietnam. Given the high involvement of the government and the dominance of several large banks in the banking system, the study also explores whether the effect of digitalization on bank profitability varies with the bank’s size and state ownership. Last but not least, the channels in which digitalization affects bank profitability are also examined.

Abstract
Purpose
The purpose of this study is to examine whether a bidirectional relationship between bank risk and market discipline may exist in Southeast Asia.
Design/methodology/approach
A simultaneous equations model with a three-stage least squares estimator is used to examine the interrelationships between bank risk and market discipline using a sample of 79 listed banks in five countries in Southeast Asia (ASEAN-5) from 2006 to 2019.
Findings
The findings show a two-way relationship between bank risk and market discipline. In particular, market discipline has a negative impact on bank risk, while there is a positive relationship between bank risk and market discipline. A bidirectional relationship between them still holds when using an alternative measure of bank risk in subsamples, controlling for the global financial crisis and governance indicators.
Practical implications
The findings indicate that market discipline can reduce bank risk. Meanwhile, a positive impact of bank risk on market discipline reemphasizes that market discipline is a powerful tool to ensure banks do not have excessive risk-taking. Nonetheless, the findings suggest that further implementation of market discipline as the third pillar of the Basel framework is necessary for the banking systems in ASEAN-5.
Originality/value
To the best of the authors’ knowledge, this study is the first attempt to investigate the interrelationship between bank risk and market discipline in Southeast Asia.

Abstract
Purpose
The purpose of this study is to carry out an empirical investigation about how the level of market concentration or competitiveness of the banking system and institutional quality are associated with bank’s financial stability.
Design/methodology/approach
This study uses dynamic panel data techniques on the sample of 133 developing and emerging countries over the years 2002–2020.
Findings
The authors document several significant findings. First, there is evidence that bank stability is positively associated with the level of market concentration. The result is in line with the concentration–stability view that banks operating in a more concentrated market tend to be more stable than those in a less concentrated market. Second, the results confirm that the quality of the institutional environment plays a critical role in improving the stability of banks in developing and emerging countries. Third, the authors find that institutional development can moderate the effect of market concentration (or competitiveness of the banking system) on bank stability. Specifically, the results show that better institutional quality enhances the positive influence of bank concentration on the bank’s financial stability in developing and emerging countries. These results are robust to different specifications with the alternative measures of bank stability and market concentration.
Originality/value
This study provides further understanding regarding the effects of the level of market concentration or competitiveness of the banking system and institutional quality on bank stability in 133 developing and emerging countries over the years 2002–2020.
