This study aims to identify the relationships between the electronic word of mouth (eWOM), brand image (Brand) and online purchase intention (INT) of young customers during the coronavirus disease 2019 (COVID-19) pandemic period.

The covariance-based SEM and the multi-group invariance analysis (MGA) were applied to investigate the proposed model with the data collected via an online survey during the fourth wave of COVID-19 in Vietnam.

The results showed that eWOM quantity (eQuan) has a significant positive effect on eWOM credibility (eC) in the context of the COVID-19 pandemic. Furthermore, whereas Brand positively partially mediates the relationship between eQuan and INT, this construct plays a positively fully mediating role in the relationship between eC and INT. Finally, the results indicated that there is no significant difference in the invariance indicators related to the gender of respondents.

This study has some contributions not only to the theoretical framework for understanding the online purchase behaviour of young customers in the pandemic context, but also to the practical implications of how to use different dimensions of eWOM accordingly to enhance a company's brand image in the online business environment.

Emerging economies have been highlighted as an important growth source of the global economy. However, this group of countries has not received enough academic attention yet. Therefore, this study aims to identify the impact of research and development (R&D) expenditure on economic growth in emerging economies.

The theoretical framework of the production function is applied to quantitatively analyse the impact of R&D expenditure on economic growth with a sample of 29 emerging economies in the period between 1996 and 2019.

The panel cointegration test confirms the existence of long-run cointegration relationships between economic growth and independent variables in these emerging economies. Besides, the estimated results show that the national R&D expenditure has positive effects on economic growth from both direct and interaction dimensions. This evidence has filled the empirical research gap in the R&D-growth nexus in the case of emerging economies. Finally, while gross capital and education have positive impacts on growth, corruption has a harmful effect on economic growth in these countries.

The results highlight that policymakers should enhance R&D expenditure and R&D activities as the key national development strategy. The investment in R&D not only helps emerging economies avoid the middle-income trap but also pushes these countries to successfully join the group of developed countries.

To the best of the authors’ knowledge, this research is among the first to examine the impact of R&D expenditure on economic growth with a homogeneous sample of emerging economies. The results are obviously helpful for policymakers to use R&D as the key development strategy for supporting economic growth in emerging economies in the future.

The investment behaviour of individuals has been a major area of interest for several researchers and policymakers due to its great impact on the economy. This study aimed to assess the investment behaviour of individuals in light of their risk appetite and how financial literacy regulates this relationship.

A self-administered structured questionnaire was used to collect responses from individuals using purposive and convenience sampling techniques. Individuals were presented with 16 investment avenues widely offered by the Indian financial market to choose from to construct a hypothetical portfolio. The association between risk appetite, financial literacy and the composition of the hypothetical portfolio was analysed using a gologit model.

Increased risk appetite increased the probability of respondents creating a portfolio with a greater proportion of risky assets and less diversification. Lower levels of financial literacy pointed towards portfolios with traditional and low-risk avenues. The results also revealed a significant moderating impact of financial literacy on risk appetite and the creation of the type of a hypothetical portfolio.

Even though the intended behaviour is a close estimate of actual behaviour, there is a possibility of deviation that cannot be ignored.

The present study provides insights into how individuals make portfolio choices by incorporating risk appetite and diversification factors whilst making investment decisions, thereby expanding the literature from an emerging economy perspective. The role of financial literacy as a moderator has not been studied in the domain of hypothetical portfolio creation in India, which has been empirically explored in the current study.

This paper investigates the influence of political connections on sustainability disclosure in the context of China's Regulation 18.

The study employs a quasi-experimental approach, utilizing difference-in-difference (DiD) analysis, dynamic DiD and propensity score matching to analyze the effects of politically connected independent directors on sustainability disclosure following the implementation of Regulation 18.

Companies with politically connected independent directors show an improvement in sustainability disclosures after Regulation 18. This effect is stronger for firms facing high political pressure or lacking alternative political power. Additionally, the increase in value from sustainability disclosures compensates for the loss of politically connected independent directors, indicating a positive value impact of sustainability disclosures.

This study provides novel insights into the corporate disclosure policy in China by investigating the impact of politically connected directors on sustainability disclosure. Additionally, it sheds light on the limitations of political power and its substitution effects within companies.

This study aims to analyse the impact of the big five personality traits on the financial risk tolerance of individuals. Furthermore, it also examines the differences in personality traits and financial risk tolerance across four generations: baby boomers, Generation X, millennials and Generation Z.

The data constituted 869 responses from Indian individuals, collected using a self-administered structured questionnaire using a convenience sampling technique.

Structural equation modelling analysis showed that openness to experience, extraversion and neuroticism had a significant impact on financial risk tolerance. Multivariate analysis revealed the role of specific personality traits in predicting the financial risk tolerance of generational cohorts. Mean difference showed that millennials and Generation Z had the greatest risk tolerance, whereas the tolerance levels were lower for Generation X and baby boomers.

This research provides insights into the role of personality on financial risk-taking among generational cohorts in India. Thus, these results cannot be generalised for other risk-taking domains or outside the Indian context.

This study’s results align with the pulse rate hypothesis of generational theory and contribute to the growing field of behavioural economics and finance. It provides a perspective of the emerging economy of India, where behavioural finance studies are still at a nascent stage.

This study aims to holistically explore the academic literature on female leaders to identify the key topics and dynamics of the field.

The authors systematically review 532 papers to explore the research on female leaders; based on objective and replicable criteria, the authors identify relevant papers and thus ensure the quality of the analysis. The bibliometric analysis and visualization support us in recognizing trends in this topic.

This study outlines the state of the art over the past decade by synthesizing theoretical contexts and critically discussing the main streams of research on sustainability, firm outcomes and barriers preventing women from reaching the upper echelons. The authors also explore empirical issues and highlight areas that entail new paths for future scholars.

The research provides novel evidence of the attempt internationally to increase female participation at the top of the firm hierarchy by analyzing firm outcomes, sustainability and the constraints faced by women in achieving these careers.

The results show that the participation of women in leadership roles is not (only) a matter of compliance with current regulations. Through their ability to monitor key social and environmental issues from a long-term perspective and their attention to the internal control systems, companies more effectively pursue their financial and nonfinancial aims.

Using bibliographic and narrative analyses, this study reviews the literature on women at the top of the firm hierarchy with a focus on business research. The authors extend prior studies by investigating a larger pool of firm roles to provide a comprehensive understanding of this widely discussed topic.

The dynamism of competition in international markets requires managers to react accordingly and ensure the firm's survival and competitiveness. This study examines the impact of cognitive styles and dynamic managerial capabilities (DMC) on a firm's international performance and the mediating role of these capabilities in the relationship between cognitive styles and international performance.

This study adopts a quantitative cross-sectional research design, employing a sample of 306 firm owner-managers from exporting companies in Kosovo.

The findings suggest that managers' cognitive styles positively influence firm international performance, including their impact on DMC. Results also indicate that only managerial cognition mediates cognitive styles' effects on a firm's international performance, compared to managers' social capital.

In this study, the authors contribute to the literature by integrating cognitive styles with DMC in a transition country. Moreover, the authors demonstrate that DMC mediate the impact of cognitive styles on the firm international performance.

This paper aims to examine whether managerial sentiment, extracted from annual reports, is associated with corporate risk-taking in the context of Chinese companies. This study expands the vein of literature on overconfidence theory.

By leveraging textual analysis on Chinese listed companies’ annual reports, the authors construct firm-level managerial sentiment during 2007 and 2021 to examine how managerial sentiment influences corporate risk-taking after control for firm characteristics. Corporate risk-taking is denoted by corporate investment engagements: capital expenditures and net fixed asset investment.

Results show that incentives for corporate risk-taking are likely to increase with the positive managerial sentiment and decrease with the negative sentiment in companies’ annual reports. Positive managerial sentiment is associated with over-/under-investment and low/high investment efficiency. Further additional tests show that the managerial sentiment effect only holds during low economic uncertain years and samples of private-owned firms. Furthermore, the robust tests indicate that there is no endogenous issue between managerial sentiment and corporate risk-taking.

Annual report textual-based managerial sentiment may not perfectly reflect managers’ lower frequency sentiment (e.g. weekly, monthly and quarterly sentiment). Future studies could attempt to capture managers’ on-time sentiment by using media sources and corporate disclosures.

To the best of the authors’ knowledge, this paper is the first research to provide insights into supervising managers’ corporate decisions by observing their textual information usage in corporate disclosure. Moreover, the approach of measuring managerial sentiment might be a solution to monitoring managerial class.

This paper contributes to the literature on accounting and finance studies, adding another piece of empirical evidence on content analysis by examining a unique language and institutional context (i.e. China). Besides, the paper notes that in line with the English version disclosure, based on Chinese semantic words, managerial sentiment in the Chinese-speaking world has magnitude on corporate decisions. The research provides insights into supervising managers’ corporate decisions by observing their textual information usage in corporate disclosure. Moreover, the approach to measuring managerial sentiment may be a practical solution to monitoring managerial class.

There is growing interest in how hubris bias shapes managerial and entrepreneurial judgments and decisions and, in turn, firm strategy and performance. Based on a 44-years dataset of articles reaching the beginning of 2023, the authors offer a synthesis of hubris research published within business journals.

The authors implement a mixed-method approach offering a content representation of 600 peer-reviewed articles extracted from Scopus. The authors conduct a bibliometric investigation – employing Excel, VOSViewer and Biblioshiny software – and perform a qualitative review.

The analysis unveils four thematic clusters: hubris bias in financial policies (Cluster 1), hubris bias in restructuring deals (Cluster 2), hubris bias in entrepreneurial contexts (Cluster 3) and hubris bias in strategic decision-making (Cluster 4). Moreover, the authors infer that hubris research in business predominantly developed from three disciplinary perspectives – finance, entrepreneurship and strategic management – and progressed with limited interdisciplinary dialogue.

The authors call practitioners' attention to the impact of the hubris bias in forming financial, entrepreneurial and strategic choices. Managers get conscious of the risks of hubristic choices; hence, they implement organizational practices that move forward with unbiased (or less biased) judgments and decisions.

The authors offer an up-to-date and comprehensive view of hubris research in business. Furthermore, the authors provide an integrative framework and a research agenda.

Professional sports teams employ highly paid managers and coaches to train players and make tactical and strategic team decisions. A large literature analyzes the impact of manager decisions on team outcomes. Empirical analysis of manager decisions requires a quantifiable proxy variable for manager decisions. Previous research focused on manager dismissals, tenure on teams, the number of substitutions made in games or the number of healthy players on rosters held out of games for rest, generally finding small positive impacts of manager decisions on team success.

The authors quantify manager decisions by developing a novel measure of game-specific coaching decisions: the Herfindahl–Hirschman Index (HHI) of playing-time across players on a team roster over the course of a season.

Evidence from two-way fixed effects regression models explaining observed variation in National Basketball Association team winning percentage over the 1999–2000 to 2018–2019 seasons show a significant association between managers’ allocation of playing time and team success. A one standard deviation change in playing-time HHI that reflects a flattened distribution of player talent is associated with between one and two additional wins per season, holding the talent of players on the team roster constant. Heterogeneity exists in the impact across teams with different player talent.

This is one of the first papers to examine playing-time concentration in the NBA. The results are important for understanding how managerial decisions about resource allocation lead to sustained competitive advantage. Linking coaching decisions to wins can help teams to better promote this core product.
