This research paper aims to explore the market efficiency of stock exchanges in of ASEAN-5 countries, Indonesia, Malaysia, Singapore, Thailand, and the Philippines, during the COVID-19 pandemic. Stock market efficiency is the degree to which stock prices reflect all available relevant information. In an efficient market, stock prices will immediately rise or fall to reflect new information released by a company. This study uses the Stochastic Frontier Analysis (SFA) method to determine the efficient value over time. Market efficiency generally refers to how well financial markets in these selected countries reflect all available information, particularly in the context of the COVID-19 pandemic. SFA is useful here as it can separate random errors from inefficiencies, allowing us to isolate the impact of COVID-19 on market efficiency levels across these countries. The results show that the stock markets of ASEAN-5 countries (Indonesia, Malaysia, Thailand, Singapore, and Philippines) are efficient during the COVID-19 pandemic. Based on the hypothesis test, for the overall period of 2021 and 2023, the average efficiency ranges from 0.68 to 0.72, and for the time period/per year the average efficiency ranges from 0.66 to 0.74. The efficiency of the Philippine stock market based on time period/per year shows the average maximum efficiency in 2021 (0.74) and 2023 (0.73). While the average efficiency of the Malaysian stock market shows the minimum level of efficiency in 2020 (0.66) and 2021 (0.68).

This study aims to investigate the mediating effect of digital financial inclusion on the relationship between digital financial literacy and the financial well-being of Malaysian households, focusing on gender differences. Using quantitative research, a total of 210 responses, which contained 105 samples for each gender, were collected from households across Malaysia using a self-administered questionnaire. The research model was analyzed using Partial Least Square-Structural Equation Modelling techniques. The findings revealed significant relationships between digital financial literacy and digital financial inclusion, as well as between digital financial inclusion and financial well-being. Additionally, digital financial inclusion was found to significantly mediate the relationship between digital financial literacy and financial well-being, underscoring the importance of digital financial inclusion. The MICOM analysis results show that all constructs have good configural invariance, indicating the measures are consistent across groups. High correlations between males and females suggest similarities, but permutation tests indicate these similarities might be due to chance. Variance differences for digital financial literacy and digital financial inclusion are not significant. However, financial well-being shows a significant variance difference, suggesting less variability among males, supported by higher reliability scores for the financial well-being of males, indicating more consistent responses. Notably, the standardized beta for the digital financial inclusion – financial well-being path is higher among females, indicating a stronger influence of digital financial inclusion on financial well-being for this group. However, the direct relationship between digital financial literacy and financial well-being is insignificant for both genders.

Rapid technological advances have made financial markets more accessible and encouraged individual investors to engage in investment decision-making actively. Generation Z, or Gen Z, characterized by higher levels of digital literacy, a high sense of curiosity, and acceptance of innovation, tends to make investment decisions quickly. This study aimed to analyze the effect of technological progress, financial literacy, and financial attitudes on investors’ investment decisions. There are 125 Gen Z investors in Jakarta, Indonesia, selected as research samples using the non-probability sampling method. The survey method was employed to collect data, and the study instrument was a questionnaire. For data analysis, Partial Least Squares version 4.0 was used. The study’s findings revealed that financial literacy and financial attitude positively influence Gen Z investment decisions. Technological progress does not affect Gen Z in determining investment in the financial market. Financial literacy and financial attitude are more dominant for Gen Z investors than technological progress in determining investment allocation. This finding implies that Gen Z must improve their understanding of correct financial literacy and financial attitudes that align with individual investors’ character. Further investigation needs to reveal the insignificance of technological progress in determining investment decisions. Technological progress and financial literacy likely have the same factor characteristics related to three dimensions: knowledge, skills, and attitudes. The attitude of Gen Z investors towards the progress of financial technology by investors is preceded by good financial literacy. Therefore, it is necessary to test the relationship between variables, both mediation and moderation, in investment decisions.

This paper investigates the multifractal behavior of the six largest African stock markets, including the Johannesburg, Casablanca, Botswana, Nigerian, Egyptian, and Regional Stock Exchanges. Despite the growing significance of these markets in the global economy, there is limited understanding of their underlying dynamics, particularly regarding their multifractal properties. This lack of knowledge raises concerns about the informational efficiency of these markets, as traditional models may not adequately capture the complexities of price movements. To achieve the goals of the study, the Multifractal Detrended Fluctuation Analysis (MF-DFA) method is applied to capture the multifractal dynamics, and shuffling and phase randomization techniques are performed to identify the sources of the multifractality of the six African stock markets. The empirical results, derived from the generalized Hurst exponents, Rényi exponents, and Singularity spectrum, show that all six stock markets display multifractal behavior, characterized by irregular and complex price movements that vary across different scales and timeframes. Additionally, the study finds that both long-term correlations and heavy-tailed distributions contribute to the observed multifractality. Long-term correlations lead to persistent price trends, challenging the Efficient Market Hypothesis (EMH), while heavy tails increase market unpredictability by raising the likelihood of extreme events like crashes or booms. The findings have significant practical implications for stakeholders in African stock markets, enabling investors and portfolio managers to enhance risk assessment and develop effective trading strategies while helping market regulators improve efficiency and stability through appropriate policies. Financial institutions can also refine risk management frameworks to better account for extreme events.

The study provides empirical evidence on the cost implications of socially responsible investing (SRI) in relation to Environmental, Social, and Governance (ESG) preferences. Specifically, it examines whether socially responsible investors incur higher costs to meet non-pecuniary goals and how government involvement can offer rewards to socially responsible investors in supporting the realization of the United Nations’ Sustainable Development Goals (SDGs). Using panel data regression, this study analyzes ESG scores and financial and return data of 1,450 firm-year observations in ASEAN-5 countries over the period 2015–2022. The findings reveal that firms implementing ESG practices experience an increase in their cost of capital (CoC), supporting the notion that ESG investment requires a sacrificial cost. Even firms with low operational risks face rising CoC when implementing ESG principles. However, the study also finds that firms located in countries with better government effectiveness and stronger control of corruption benefit from a reduction in CoC, despite ESG implementation. Conversely, country risks, particularly those related to environmental pollution, exacerbate the CoC for firms adhering to ESG criteria. Overall, the results suggest that while country-level governance can reward socially responsible investors by mitigating CoC, country risks such as pollution pose additional burdens, highlighting the need for government intervention to incentivize SRI and align it with global sustainability goals.

Understanding the conditions leading to business failure and predicting them earlier is the best way for companies to overcome and minimize their harm, improve their performance, and avoid financial distress and bankruptcy. This paper aims to measure the level and trends of factors affecting financial distress in Vietnam – an emerging Southeast Asian economy, along with the managerial implications drawn from the research results. Research data were collected from 606 firms listed on the Vietnam Stock Exchange from 2018 to 2022. The Altman Z-score is used to determine the financial distress of these firms. The factors researched and tested in this study are all internal factors divided into two groups with distinct features. Non-financial factors belong to management characteristics; financial factors are typical indicators of a firm’s financial statements. The study uses OLS, FEM, and REM models to analyze the influence of financial factors (Total liability to Total assets, Sales growth, Firm size, and Firm age) and non-financial factors (Board size, CEO duality, Institutional ownership level, Independent member, and Foreign CEOs) on financial distress and GLS regression to overcome the model’s shortcomings. The results show that the factors in the research model significantly impact financial distress, of which six factors (Board size, CEO duality, Institutional ownership level, Foreign CEOs, Sales growth, and Firm age) are negatively correlated. Three other factors (Independent members, Total liability to Total assets, and Firm size) are positively correlated with financial distress.

This study examines the extent of environmental and community disclosures and evaluates how audit committee features influence such disclosures among listed firms in Bahrain and Kuwait, Gulf Cooperation Council (GCC) countries of emerging markets. The research employs an unweighted disclosure index comprising 18 items related to environmental and community disclosures, analyzing 432 firm-year observations across Bahrain and Kuwait covering a nine-year period (2015–2023). Three audit committee features (independence, number of meetings, and size) along with the number of other board committees are examined in this empirical investigation. Descriptive analysis indicates that the sampled firms offer 44.25% and 60.60% of environmental and community information, respectively, signaling a satisfactory disclosure level in Bahrain and Kuwait. This demonstrates progress compared to prior studies in GCC countries. Hierarchical Multiple Regression models demonstrate that all four models significantly describe the dependent variables. Regression model four exhibits the highest explanatory power in explaining community information. Audit committee independence and size emerge as determinants of community information, while only audit committee independence is associated with environmental information. The results of this study bear significant implications for governmental bodies and regulatory authorities aiming to strengthen disclosure regulations and promote corporate governance frameworks within GCC nations.

The study aims to analyze the co-movement between oil prices, BRICS nations’ exchange rates, and stock markets. Grasping these interrelationships is essential for understanding how global energy price shifts broadly affect the economies, particularly those of developing nations.
The study employs wavelet coherency analysis on daily data, examining the association between crude oil (Brent crude), exchange rates (Brazilian Real, Russian Rubble, Indian Rupee, Chinese Yuan, and South African Rand), and stock markets (BOVESPA of Brazil, Moscow Exchange of Russia, Nifty50 of India, Shanghai Composite of China, and JSE FTSE of South Africa) across both temporal and frequency domains.
This study reveals strong comovements, especially during periods of global economic instability, such as the impact of the COVID-19 pandemic and the Russia-Ukraine war. During such periods, oil prices and stock market indices tend to move in tandem, while oil prices and exchange rates show an inverse relationship. The study also reveals a decoupling of crude oil from both share markets and exchange rates during normal economic conditions. This decoupling suggests that outside of a chaotic period, the relationships weaken. However, the co-movements among the variables for China are notably weaker, even during economic upheavals, than in other BRICS nations. Understanding these relationships can aid in informed decision making and strategies in the face of global economic turmoil.

The global adoption of Central Bank Digital Currencies (CBDCs) represents a pivotal shift in monetary systems, driven by technological advancements and economic imperatives. While a small number of official digital currencies are in circulation, many nations are launching pilot programs to address financial inclusion challenges and enhance economic resilience. This study aims to identify the determinants of digital currency adoption across 116 countries, using logistic regression to analyze the effects of economic, technological, institutional, and financial factors.
The results show that higher GDP levels significantly increase the likelihood of active CBDC adoption by 332.1 percent and pilot adoption by 212.6 percent, reflecting the role of economic development. Greater internet usage improves the odds of active adoption by 12.7 percent and pilot adoption by 13.4 percent, while financial inclusion indicators, such as account ownership, increase the likelihood of adoption by 59 percent for active initiatives and 141 percent for pilot projects. Monetary freedom positively influences active adoption by 31.1 percent, and higher interest rates increase the odds by 20.8 percent. Conversely, business freedom negatively affects active adoption by 27.5 percent and pilot adoption by 29.1 percent, suggesting that countries with strong private-sector digital payment solutions may rely less on CBDCs.
These findings represent the transformative potential of digital currencies to improve financial inclusion and economic participation. Policymakers should prioritize investments in digital infrastructure and financial inclusion initiatives to facilitate the integration of digital currencies into national economies and empower underserved populations globally.

Investor behavioral factors determine the investment decisions of individual investors in the stock market. The study investigated behavioral factors driving investment decisions in Nepal’s stock market, contributing to existing literature. The behavioral factors comprise heuristics, prospects, and herding as predictors and investment decisions as a response variable. Thus, the study adopted a descriptive and analytical research design to test the research hypotheses and resolve the research questions and issues. A survey was conducted among individual investors registered with Nepal’s trading management system (TMS). A total of 526 structured questionnaires were distributed to targeted respondents, and only 350 useful questionnaires (66.54 percent) were received. The survey data of cross-sectional type were encompassed with a random clustering sampling method for this study. Further, the study employed descriptive statistics to depict the characteristics of respondents’ profiles, correlation analysis to assess the association between predictors and response variables, and linear regression analysis to investigate the impact of predictors on response variables. Similarly, Cronbach’s alpha was tested to observe reliability in the study. The survey findings showed a positive and significant association between heuristics and investment decisions (β = 0.088, p < 0.05). The prospect is positively linked with the individual’s investment decision but found insignificant (β = 0.011, p > 0.05). Finally, herding found a positive and significant association with investment decisions (β = 0.235, p < 0.05). The findings of this study contribute to existing theory and can be a benchmark for decision-makers and policymakers, investors, and others.

Transfer pricing practices remain a challenge for tax authorities in various countries because they can be used to reduce tax payments. This study aims to explore the impact of ownership structure on transfer pricing practices, focusing on how board experience and executive characteristics act as moderating factors. Additionally, the study considers three control variables: company size, debt to equity ratio, and ROE. The analysis encompasses all publicly listed companies on the Indonesia Stock Exchange, utilizing panel data analysis and moderated regression techniques. The dataset comprises 2,480 entries from 310 companies over an eight-year span from 2015 to 2022. The findings indicate that concentrated ownership positively influences transfer pricing, whereas managerial ownership exerts a negative influence. Meanwhile, foreign, institutional, and family ownership show no significant impact on transfer pricing activities. The experience of the board of directors only moderates the effect of ownership concentration on transfer pricing, with no other significant moderating effects observed. In contrast, executive characteristics successfully moderate the impact of foreign ownership, managerial ownership, and ownership concentration on transfer pricing but not institutional or family ownership.

The study reviews the application of machine learning tools in financial investment portfolio management, focusing on cluster analysis for asset allocation, diversification, and risk optimization. The paper aims to explore the use of clustering analysis to broaden the concept of portfolio diversification beyond traditional volatility metrics. An open dataset from Yahoo Finance includes a ten-year historical period (2014–2024) of 130 actively traded securities from international stock markets used. Dataset selection prioritizes top liquidity and trading activity. Python analytical tools were employed to clean, process, and analyze the data. The methodology combines classical Markowitz optimization with clustering analysis techniques, highlighting variance-return trade-offs. Various asset characteristics, including annualized return, standard deviation, Sharpe ratio, correlation with indices, skewness, and kurtosis, were incorporated into the clustering models to reveal hidden patterns and groupings among financial assets. Results show that while clustering enhances insights into asset diversity, classical approaches remain historically superior in optimizing risk-adjusted returns. This study concludes that clustering complements, rather than replaces, classical methods by broadening the understanding of diversification and addressing many diversity factors, such as metrics of the technical, graphical, and fundamental analysis. The paper also introduces the diversity rate based on clustering, which measures the variance balance by all features within and between clusters, providing a broader perspective on diversification beyond traditional metrics. Future research should investigate dynamic clustering techniques, integrate fundamental economic indicators, and develop adaptive models for effective portfolio management in evolving financial markets.

Corporate structure decisions are the foundation of a company’s legal, financial, and operational framework, influencing diverse issues, from liability and tax obligations to growth potential and public perception. The paper aims to analyze the effect of firms’ financial performance on capital structure decisions. Firm size and corporate governance were taken as moderators and mediators, respectively. The study is based on 23 non-banking public firms listed on the Nepal Stock Exchange, adapting a causal-comparative research design. The moderated mediation model was tested using the Process Macro to assess the impact of corporate governance scores on the relationship between firm performance and capital structure. The result shows that firm performance positively and significantly impacts capital structure decisions. The results revealed no effect of corporate governance on capital structure decisions; however, the moderated mediation impacts of corporate governance and firm size have been reflected in the financing decision. This study extends previous research with the moderated mediation effects of corporate governance and the size of non-banking firms on their financing decisions. The results encourage managers to raise debt funds for those firms that observe the firm’s size, providing practical insights into business decisions. The study also has policy and theoretical implications.

This study examines how perceived security and privacy influence user ratings of cryptocurrency applications, which are critical for adoption and satisfaction amid the growing popularity of blockchain technologies and rising concerns over information security in online platforms and mobile apps. The study focuses on mobile applications from the Android app market. It used text mining methods to investigate over 64 thousand text-based user reviews and star ratings of over 140 cryptocurrency-related mobile applications available in the Google Play store. Using a partially supervised machine learning approach, this study first identified reviewer sentiment related to privacy and security, then employed ordinal regression analysis to examine the data to reveal the relationship between perceived security threats, privacy concerns, and app ratings. This study found that crypto apps average 3.84 out of 55 stars, which is higher than Productivity apps (3.46) but lower than FinTech (4.29) and Banking (4.25) apps. Ordinal regression analysis revealed security and privacy threats negatively impact ratings, while robust security measures improve them, with a model Pseudo R² of 0.25. These results have implications for both cryptocurrency app developers and platform managers, offering insights for enhancing user experiences and informing future research endeavors in this domain. It contributes to the literature by integrating the Protection Motivation Theory with sentiment analysis and provides a structured framework for developing an understanding of user behavior in the context of cryptocurrency apps.

This study investigates the investment preferences of institutional investors in Indonesia, focusing on the factors influencing stock selection. A comparative analysis is conducted between pressure-sensitive and pressure-insensitive investor groups to explore how different factors such as corporate social responsibility, corporate governance, shariah-compliant stocks, and financial indicators, including profitability, liquidity, and risk, affect their investment decisions. Data from 938 observations across 253 manufacturing companies listed on the Indonesia Stock Exchange were analyzed using panel data regression. The period was chosen because it captures a stable economic period in Indonesia, allowing for an accurate assessment of investment patterns without major external shocks. The results reveal that institutional investors favor stocks listed on the Indonesia Shariah Stock Index (ISSI), perceived as low-risk investments. Pressure-sensitive investors, such as banks and insurance companies, prefer companies with close business affiliations, while pressure-insensitive investors, such as mutual funds and pension funds, prioritize financial performance and corporate governance. Additionally, the study finds that the debt-to-asset ratio and inclusion in the Shariah index significantly affect institutional ownership, indicating a preference for leveraged companies with ethical investment profiles. This study provides a deeper understanding of the varying preferences between institutional investor groups, highlighting the significance of ethical considerations, financial stability, and corporate governance in emerging markets.

Social media significantly influences investor behavior, particularly in emerging markets like the Egyptian stock market. This study examines its impact on trading frequency, herding behavior, and overconfidence among Egyptian investors. Data were collected through a structured survey of 300 active investors, distributed via two prominent Facebook pages: “The Popular Union of Investors in the Egyptian Stock Market” and “Investment in the Egyptian Stock Market.” The sample was determined using Cochran’s formula for large, undefined populations, achieving a 78% response rate from the 385 recommended respondents. A descriptive quantitative approach was employed, utilizing correlation tests and regression analysis to assess relationships between social media engagement and investor behavior.
Findings indicate that social media usage significantly increases trading frequency, as investors make more reactive decisions based on rapidly available information. Herding behavior is also positively associated with social media engagement, demonstrating that investors tend to follow market trends and decisions discussed in online communities. Additionally, social media exposure fosters overconfidence, leading to increased risk-taking behavior. These insights highlight the critical role of social media in shaping investor behavior, with practical implications for regulators, financial advisors, and individual investors. Regulators should promote investor education on the cognitive biases linked to social media engagement, while financial advisors must address its influence on client decision-making. Future research should explore platform-specific features, such as visual content and influencer-driven financial advice, to better understand their effects on investment strategies.

The study aims to investigate the effect of research and development (R&D) capitalization on revenue-expense matching in the pharmaceutical and biotechnology industries, with particular attention to the moderating role of corporate governance and the influence of regulatory intervention. While capitalizing R&D expenditures enhances the relevance of financial information and positively impacts firm value, it also increases the risk of earnings management, potentially disrupting revenue-expense matching. Using a fixed-effects regression model, this study analyzes 1,350 firm-year observations from Korean listed firms in the bio-pharmaceutical sector from 2012 to 2022. The sample includes firms with financial statements, auditor data, and detailed disclosures on R&D expenditures, encompassing capitalized R&D costs, R&D expenses recognized in income statements, and those classified as manufacturing costs. The results indicate that R&D capitalization generally weakens revenue-expense matching in these industries. However, the adverse effects are mitigated by the effective implementation of corporate governance mechanisms. Additionally, the Financial Supervisory Service’s thematic supervision of R&D accounting practices has significantly improved revenue-expense matching. Prior to the supervision period (2012–2017), firms exhibited significant discretionary capitalization practices, undermining revenue-expense matching. Following the supervision (2018–2022), improved adherence to accounting standards has enhanced matching quality, underscoring the regulatory intervention’s effectiveness. These findings contribute to the literature by demonstrating that while discretionary R&D capitalization can impair revenue-expense alignment, strong corporate governance and adherence to accounting standards can offset these negative effects. The study provides valuable implications for future research and industry practices, particularly in navigating the trade-offs associated with R&D capitalization.

This study examines how consumer, investor, and manager sentiment explain US stock excess returns over 23 years. Its novelty resides in integrating the sentiments of three different types of economic and financial agents. It also performs a segmented temporal analysis using rolling window techniques, to assess sentiment’s impact across different time horizons. The empirical analysis utilizes the Paris-Winsten and Newey-West estimators, along with the ARMAX model to address autocorrelation and heteroscedasticity in linear regression, providing robust standard errors and reliable statistical inferences. The autoregressive moving average models estimate excess return based on the past values, shocks, and external variables. Combining the Fama-French five-factor model with the sentiment factor enriches the analysis. The study’s findings indicate that higher consumer optimism negatively impacts excess returns, as investors may anticipate a future decline in the stock market due to an existing overheated economy. Investor sentiment exhibits mixed behavior, where higher uncertainty may increase stock returns due to previous oversold markets creating opportunities for investors or due to the closing of short positions, which will also increase stock demand. It is also related to decreased stock returns depending on the proxy used. As for managers’ sentiment, this work did not demonstrate a relevant relationship between this sentiment and stock returns. The study also reveals that the importance of sentiment determinants of those three agents changes over time. The findings support behavioral models of asset pricing, which incorporate both market fundamentals and the psychological characteristics (sentiment) of different market participants.

This article examines the influence of networking capital, leverage, and profitability on a firm’s cash holdings. A firm’s level of cash reserves is a trade-off between financing, investment, and market climate. To achieve this trade-off, firms maintain cash reserves as a preservative motive. A firm with optimized working capital will have low working capital requirements, which will result in an increase in the firm’s cash reserves. In this context, the present study acquires data from 51 firms in the manufacturing sector registered on the TASI (Tadawul All Share Index) from 2014 to 2022. The study considers cash as a regressand, net working capital, profitability, and leverage as predictor variables, and firm size as a control variable. The study observed that the manufacturing firms in Saudi Arabia invest excess cash in profitable projects. The study wrapped up the results by using pooled regression and panel regression with fixed and random effects. Panel regression results report a negative and significant influence of net working capital on firms’ cash reserves with a coefficient of –0.09. Leverage positively influences the firms’ cash reserves with a coefficient of 0.05 and is significant, and profitability is positive and significant with a coefficient of 0.04. Further, firm size is positive and significant with a coefficient of 0.004.

This study investigates whether higher foreign shareholder equity improves labor investment efficiency in South Korean publicly listed firms. Labor investment, like capital investment, plays a crucial role in shaping corporate performance and value. It involves continuous cash outflows and poses challenges during restructuring, such as downsizing. Foreign shareholders are known to take on a monitoring role in Korean firms, potentially leading to more efficient labor investment decisions.
To assess the impact of foreign shareholder involvement on labor investment efficiency, regression analysis was conducted using data from 2,699 firm-year observations from firms listed on the Korean stock exchange during the pre-pandemic period (2016–2019). Labor investment inefficiency was measured as the absolute difference between actual and expected labor investment levels, considering both over- and under-investment as inefficiencies.
The analysis revealed a significant negative relationship between foreign ownership and labor investment inefficiency. Specifically, a regression coefficient of –2.220 (p-value: 0.027) indicates that higher foreign shareholder equity is associated with lower labor investment inefficiency. Further analysis, separating the sample into over-investment and under-investment groups, found that the coefficient for foreign ownership in the under-investment group was –1.920 (p-value: 0.055), significant at the 10% level. These findings suggest that foreign shareholders, through their monitoring role, help reduce information asymmetry, decreasing inefficiencies in labor investment decisions.

Prior research states that during extreme uncertainties stock prices deviate from their fundamentals. This study examines the cross-section of share price returns during the COVID-19 and pre-COVID periods to determine how investors’ reaction to prior earnings volatility is affected by the COVID-19-induced ambiguity. The sample consists of 840 firms listed on the New York Stock Exchange (NYSE) from January 1, 2020 to May 31, 2021. Consistent with the notion that ambiguity-aversion is not a universal phenomenon, COVID-period stock returns exhibit a positive (β = 0.23) and statistically significant relationship with prior earnings volatility. In contrast, the stable period returns show a very weak, if any, correlation with prior earnings volatility. The positive relationship is more pronounced for firms that experience greater information asymmetry. When comparing the results with previous research, it appears that different crises evoke varied levels of ambiguity-aversion possibly because of the ways in which each crisis’s features and anticipated outcomes influence how the market reacts. Thus, before crafting responses to a crisis, policymakers and firms should thoroughly examine the crisis and identify the underlying causes, dynamics, and possible effects on decision-makers’ ambiguity-aversion behavior.

Corporate governance has been widely applied in developed countries to promote accountability, transparency, and efficiency within corporations. In Vietnam, as the country transitions toward integrating international standards, corporate governance has become an emerging and critical area of focus. Therefore, this study aims to examine the relationship between corporate governance characteristics and corporate financial distress. The study utilizes the dataset of about 500 listed companies in the Vietnam stock exchange during 2014–2022. Feasible generalized least squares regression (FGLS) is employed to account for the heteroskedasticity and autocorrelation problems. Regression results show that frequent board meetings and more gender-diverse boards improve corporate financial health, while an increase in board members and duality roles have negative effects. Duality is often associated with increased agency problems, inefficient capital usage, and higher risk levels that reduce financial health. However, the impact is different in complex firms measured by book-to-market ratio and operating cycles. In complex firms, duality proves valuable by providing unified leadership and enabling active, clear management strategies. This can be explained by the fact that clear and flexible strategies outweigh the benefits of separation between the chairman and Chief Executive Officer.
