Abstract
Purpose
Green finance aims to promote sustainable financial activities, environmental conservation and ecological balance. This study examines how renewable energy consumption (REN), technological innovation (TEC) and green finance (GRF) influence CO2 emissions in Vietnam from 2000 to 2022.
Design/methodology/approach
We utilize a novel three-stage methodology including quantile-on-quantile regression, wavelet coherence and wavelet-quantile regression to explore the relationship in the structure of intercorrelation in terms of quantile, time and frequency.
Findings
The findings show that Vietnam will increase environmental quality for higher green development. Specifically, there is a negative influence of TEC, REN and GRF on CO2 emissions across different quantiles and timescales.
Practical implications
The study recommends policies that support green development and reduce carbon emissions, such as increasing the use of renewable energy and conducting well-planned research to achieve a carbon-free, sustainable environment.
Originality/value
This article looks into the effects of GRF, TEC and REN on CO2 emissions in Vietnam. Some studies argue that green development in underdeveloped nations is insufficient to reduce CO2 emissions, thereby limiting the sample to a few advanced economies. Adopting diverse methodologies demonstrates the varied and intricate nature of understanding CO2 drivers. Additionally, our work makes detailed policy implications for Vietnam to meet its net-zero emission target and achieve sustainable development by 2050.

Abstract
Purpose
The aim of this research is to examine the moderating impact of financial development (FD) on the relationship between remittance inflows and economic growth in 82 developing countries.
Design/methodology/approach
This research utilized dynamic panel data estimation, specifically the system generalized method of moment (GMM), on a panel data set comprised of 82 developing economies from 2000 to 2022.
Findings
The findings indicate that the interaction of remittances and FD proxies by size and depth creates a substitute effect to reduce economic growth. In contrast, the interaction of remittances and FD proxy by efficiency creates complementarity by attracting remittances that accelerate economic growth. The robustness of the findings is further checked across upper- and lower-middle-income countries, respectively.
Research limitations/implications
This study assists policymakers in attracting remittance inflows through FD and spending them in sustainable, productive ways to boost economic growth in developing economies.
Social implications
The policymakers should have interactive remittances–FD policies to improve not only economic growth but also the social welfare of the developing economies.
Originality/value
This work contributes significantly to the underexplored literature on the moderating impact of FD on the relationship between remittance inflows and economic growth in the developing countries context. This research utilizes maximum proxies of FD that not only examine the remittance but also investigate how FD various proxies shape the relationship between remittances and economic growth.

Abstract
Purpose
This investigation delves into the rationale behind the preferential applicability of the non-Newtonian nanofluid model over alternative frameworks, particularly those incorporating porous medium considerations. The study focuses on analyzing the mass and heat transfer characteristics inherent in the Williamson nanofluid’s non-Newtonian flow over a stretched sheet, accounting for influences such as chemical reactions, viscous dissipation, magnetic field and slip velocity. Emphasis is placed on scenarios where the properties of the Williamson nanofluid, including thermal conductivity and viscosity, exhibit temperature-dependent variations.
Design/methodology/approach
Following the use of the OHAM approach, an analytical resolution to the proposed issue is provided. The findings are elucidated through the construction of graphical representations, illustrating the impact of diverse physical parameters on temperature, velocity and concentration profiles.
Findings
Remarkably, it is discerned that the magnetic field, viscous dissipation phenomena and slip velocity assumption significantly influence the heat and mass transmission processes. Numerical and theoretical outcomes exhibit a noteworthy level of qualitative concurrence, underscoring the robustness and reliability of the non-Newtonian nanofluid model in capturing the intricacies of the studied phenomena.
Originality/value
Available studies show that no work on the Williamson model is conducted by considering viscous dissipation and the MHD effect past over an exponentially stretched porous sheet. This contribution fills this gap.

Abstract
Purpose
The recent meeting of G-20 world leaders, held in New Delhi, in 2023, highlighted that the physical effect of climate change has considerable macro-economic costs at the national and global levels and they have also pledged to accelerate the clean, sustainable and inclusive energy transition along a variety of pathways. Climate change could pose various emerging risks to the firm’s operational and financial activities, specifically for those which are belonging to the energy sector. Thus, this study aims to investigate the impact of climate risks on the financial performance of select energy companies from G-20 countries.
Design/methodology/approach
The study considered 48 energy companies from G-20 countries as the sample for the period of 2017 to 2021. To measure the climate change-related physical risks, the study has considered the ND-GAIN climate vulnerability score and the firm’s financial performance has been measured by return on assets, return on equity, return on capital used and price-to-book ratio. To examine the impact of climate risks on the financial performance of the sample companies, the authors have used pooled ordinary least squares (OLS) and fixed/random effect regression analysis and required data diagnosis tests are also performed.
Findings
The empirical results suggested that climate risks negatively impacted the financial performance of the sample companies. The market performances of the firms are also being impacted by the physical climate change. The results of panel data regression analysis also confirmed the robustness of the empirical results derived from the pooled OLS analysis suggesting that firms that operated in a less climate-risky country, financially performed better than the firms that operated in a more climate-risky country.
Practical implications
The paper has significant practical implications like it could be helpful for the policymakers, investors, suppliers, researchers and other stakeholders in developing deeper insights about the impact of climate risks on the energy sectors from an international perspective. This study may also help the policymakers in developing policies for the management of climate risk for the energy sector.
Originality/value
This study adds insights to the existing literature in the area of climate risks and firm’s financial performance. Moreover, this may be the first study that attempts to evaluate the impact of climate risks on the financial performance of select energy companies from the G-20’s perspective.

Abstract
Purpose
With the development of Web information systems, steel e-commerce platforms have accumulated a large number of quality objection texts. These texts reflect consumer dissatisfaction with the dimensions, appearance and performance of steel products, providing valuable insights for product improvement and consumer decision-making. Currently, mainstream solutions rely on pre-trained models, but their performance on domain-specific data sets and few-shot data sets is not satisfactory. This paper aims to address these challenges by proposing more effective methods for improving model performance on these specialized data sets.
Design/methodology/approach
This paper presents a method on the basis of in-domain pre-training, bidirectional encoder representation from Transformers (BERT) and prompt learning. Specifically, a domain-specific unsupervised data set is introduced into the BERT model for in-domain pre-training, enabling the model to better understand specific language patterns in the steel e-commerce industry, enhancing the model’s generalization capability; the incorporation of prompt learning into the BERT model enhances attention to sentence context, improving classification performance on few-shot data sets.
Findings
Through experimental evaluation, this method demonstrates superior performance on the quality objection data set, achieving a Macro-F1 score of 93.32%. Additionally, ablation experiments further validate the significant advantages of in-domain pre-training and prompt learning in enhancing model performance.
Originality/value
This study clearly demonstrates the value of the new method in improving the classification of quality objection texts for steel products. The findings of this study offer practical insights for product improvement in the steel industry and provide new directions for future research on few-shot learning and domain-specific models, with potential applications in other fields.

Abstract
Purpose
This study aims to explore the relationship between transformational leadership and proactive customer service performance (PCSP) in the airline industry, considering self-efficacy and emotional intelligence as mediators.
Design/methodology/approach
Bandura’s self-efficacy theory was used for formulating hypotheses. Data were gathered from 500 frontline employees and 30 supervisors to create subordinate dyads, resulting in a final sample size of 370 participants. Structural equation modeling was employed for the purpose of data analysis.
Findings
The results indicated that supervisors’ transformational leadership impacted the self-efficacy and emotional intelligence of service and frontline employees, thereby influencing PCSP. Self-efficacy and emotional intelligence of frontline employees were positively correlated with PCSP. These findings add to the existing literature by providing empirical proof of a positive association between transformational leadership and perceived customer service performance. Furthermore, this study supported the mediating roles of self-efficacy and emotional intelligence of frontline employees as mediators, showing their importance in translating transformational leadership behaviors into enhanced customer service performance.
Practical implications
The airline sector will benefit significantly from the findings of this research. It highlights the significance of transformational leadership in improving PCSP. Organizations should emphasize the creation and growth of transformational leaders capable of inspiring and motivating staff to provide excellent customer service. In addition, the research highlights the significance of self-efficacy and emotional intelligence as factors that mediate the relationship between transformational leadership and PCSP. Organizations may foster PCSP by investing in training and development programs that seek to improve workers’ self-efficacy and emotional intelligence. These programs may help participants gain confidence in their ability to deliver excellent customer service as well as improve their knowledge.
Originality/value
This research paper presents novel theoretical and practical developments in the airline industry. This research paper collected data in two phases from supervisor–subordinate dyads.

Abstract
Purpose
Leadership’s dark side has been on the rise, negatively affecting organizations. The phenomenon, however, is not as simple as it seems. Based on social exchange and conservation of resource theories, current research aims to explore the impact of psychological entitlement on despotic leadership, ultimately leading to instigated workplace incivility. Moreover, emotional exhaustion was tested as a mediator and Islamic work ethics as a moderator.
Design/methodology/approach
This study aims to examine the effect of dark side of leadership and for this, the survey approach was used to collect data from 402 bankers from Pakistan’s twin cities (Islamabad and Rawalpindi).
Findings
The results showed that psychological entitlement leads to despotism and despotic leaders become a reason for instigated workplace incivility. Results also showed that emotional exhaustion mediated, and Islamic work ethics moderated the relationship.
Practical implications
Bankers have a demanding job which is further exacerbated by despotic leaders feeling psychologically entitled and instigating employees toward uncivil behaviors as they experience emotional exhaustion. Despotic leaders need to be dealt with to reduce instigated incivility and Islamic work ethics can also aid in improving employee behavior.
Originality/value
Literature available on both antecedents and effects of the leadership’s dark side is limited, and this study strives to contribute by extending the literature available on psychological entitlement, despotic leadership and instigated workplace incivility relationships.

Abstract
Purpose
Drawing on the conservation of resources (COR) theory, this study aims to examine the effects of servant leadership and despotic leadership on employees’ happiness at work (HAW) through job crafting.
Design/methodology/approach
To test the hypothesized relationships, the data were collected from 309 Pakistani employees. Structural equation modeling was used to analyze the data.
Findings
The findings showed that servant leadership is an optimal leadership style for creating employees’ HAW. In addition, job crafting was found to mediate the effects of servant leadership on employees’ broad-based positive attitudinal outcome (HAW). Moreover, results showed that despotic leadership negatively influences employees’ HAW through job crafting.
Originality/value
This study is novel as it investigates how newer forms of positive (servant) and negative (despotic) leadership styles influence employees’ multidimensional attitudinal outcome (HAW) via job crafting. By doing so, this research extends the nomological network of servant leadership, despotic leadership, job crafting and HAW.
