This paper aims to examine the impact of bank managerial ability on the cost of loans using an extensive data set of US banks from 2001:Q1 to 2021:Q2.

First, the authors use multiple fixed-effects estimation to estimate the impact of managerial ability on bank loan pricing. In addition, the authors also perform different econometrics regression methods to test the robustness of the model including: Prais–Winsten regression, Newey–West regression and the Fama McBeth method, instrumental variable regression, propensity score matching method and quantile regression.

The results show that banks with higher managerial ability tend to provide loans with lower costs, and this effect is stronger at larger banks. In addition, research results from the quantile regression model show that the negative impact of managerial ability on the cost of loans will be stronger at banks with higher lending costs.

To the best of the authors’ knowledge, this study is one of the first to investigate this relationship between managerial ability and bank loan pricing from the supply side. In addition, this paper examines the impact of bank managerial ability on the loan costs of banks of different sizes, as well as differs across the distribution of the dependent variable. Therefore, this paper is of particular interest to regulators and policymakers.

Over energy consumption is one of the causes of global warming and climate change. To deal with this issue, using energy-efficient appliances is strongly encouraged and cultivating consumer loyalty toward energy-efficient appliances is crucial for long-term sustainability. This study investigates the effects of multiple dimensions of perceived value on consumer satisfaction and three outcomes of consumer loyalty (i.e. willingness to pay a premium, repurchase intention and word-of-mouth intention), considering the moderating role of the product category.

Quota sampling based on age and gender and snowball sampling methods were applied to recruit 423 participants for this study. A combination of partial least squares structural equation modeling (PLS-SEM), importance-performance map analysis (IPMA) and necessary condition analysis (NCA) was employed to examine the proposed model.

Functional, price, emotional and environmental values positively impact consumer satisfaction, enhancing the three dimensions of consumer loyalty. The product category moderates the effects of perceived value dimensions on consumer satisfaction. Moreover, the IPMA results highlight that functional value and environmental value are the most essential but underperforming value attributes. The NCA results indicate that social value is a necessary condition for consumer satisfaction.

This study is one of the pioneers in integrating PLS-SEM, IPMA and NCA approaches to comprehensively unpack the relationships between perceived value dimensions, consumer satisfaction and consumer loyalty in the context of energy-efficient appliances. The findings offer theoretical and practical importance for academics, retailers, producers and policymakers to encourage consumer loyalty toward energy-efficient appliances.

Inspired by the internationalisation paths to prosperity of small and medium-sized enterprises (SMEs), where narcissistic leaders are diligent about organisations but also pursue their dark goals, this study aims to concurrently examine two avenues for the internationalisation of narcissistic leaders in SMEs concerning the function of team organisational citizenship behaviours (OCB): corporate social irresponsibility (CSI) and digital business model innovation (BMI).

This study utilised a quantitative design emphasising mature theory research, and data was analysed using multiple regression analysis and Hayes' process model. The data for this study was collected via surveys from 270 SMEs in Vietnam.

The study showed that narcissistic Chief Executive Officers (CEOs) can penetrate the global market profoundly by utilising both the righteous path, which is based on the power of the times via BMI, and the unethical path, CSI. However, team devotion via OCB can mitigate the unethical conduct of narcissistic CEOs.

The study endeavoured to find a path to internationalisation for SMEs in emerging markets with high economic openness and increasingly close connections with international markets, via two strategies for SMEs to conquer the international market more successfully, and with utilising the foundations of CEO narcissism and team citizenship behaviour.

This study contributed to the theory of SME internationalisation by employing the resource-based view and upper-echelon theory, with the updated Uppsala model as its foundation.

Drawing from agency and comprehension theories, this paper aims to examine the influence of annual report readability (ARR) on financial reporting quality (FRQ), with a focus on how information asymmetry moderates this relationship.

The study uses a sample of 467 listed firms in Vietnam from 2015 to 2021. To analyze the relationship between ARR and FRQ, this paper employs a Generalized Method of Moments (GMM) regression, incorporating information asymmetry as a moderating factor.

The research findings show that ARR has a positive and significant impact on the FRQ of Vietnamese-listed firms. This paper also finds that information asymmetry significantly and partially moderates the relationship between ARR and FRQ. Specifically, ARR can help alleviate the level of information asymmetry and contributes to improved FRQ.

From a practical perspective, this paper provides empirical evidence for managers, investors and related government departments to evaluate the effects of ARR and offers regulators a method to help improve the transparency of the stock market. More importantly, the results of this study have reference value for scholars and practitioners in developing countries like Vietnam.

From a theoretical perspective, our study adds to the growing literature on ARR, expands the scope of ARR research, elaborates on relevant economic consequences of ARR and complements the literature on the determinants of FRQ.

This study aimed to (1) examine the impact of restaurant customers’ emotional self-regulation on ethical evaluations and judgments on their food waste reduction behaviors and (2) explore the influence of ethical judgments and evaluations on food waste reduction behaviors in restaurants.

Data were collected through a face-to-face survey at 20 restaurants in three major cities in Vietnam, namely Hanoi, Da Nang and Ho Chi Minh City. Responses from 870 restaurant customers were used to analyze the data. Partial least squares structural equation modeling (PLS-SEM) was used to examine the path effects.

Based on the model of Hunt and Vitell (1986), this study incorporates the role assessment of emotional self-regulation, deontological and teleological evaluation into the research model to examine consumers’ ethical judgments and ethical behaviors as food waste reduction behaviors. All hypotheses were accepted with the study’s data. From there, the author makes some implications for state management agencies and businesses in promoting consumers’ food waste reduction behaviors.

Several recommendations should be made based on the results of the study. First, there is a need for guidelines for people to regulate emotions to match ethical consumption decisions, such as increasing the amount of study time for subjects on ethics and emotion management, teaching and promoting ethical values and standards as well as discussing ethical perspectives on food waste. Second, governments and businesses need to promote communication about the consequences of food waste on television, radio, newspapers and social networks, should have anti-food waste posters and should even popularize charging for cases of ordering or taking food that is beyond personal needs.

First, this is believed to be the first study to investigate the role of emotions on ethical consumption decisions in general and food waste reduction in particular. Second, this study is one of the few studies that examine the influence of deontological evaluation, teleological evaluation and ethical judgments on food waste reduction behaviors (reduce, reuse and recycle). Finally, this is one of the few studies that comprehensively examines food waste reduction behaviors, including reduce, reuse and recycle.

This study aimed to develop a moderated mediation model to explain the relationship between artificial intelligence (AI) awareness and counterproductive work behavior, turnover intention. In this model, the authors assumed that interpersonal conflict mediates and that perceived organizational support and competitive psychological climate moderates the relationship between AI awareness and counterproductive work behavior, turnover intention.

An empirical study based on a sample of 1,129 Vietnamese employees at some enterprises of 6 fields with the highest level of AI application. Structural equation modelling analysis was used for hypothesis testing.

Analysis of the data demonstrates that AI awareness has a relationship with counterproductive behavior, interpersonal conflict and turnover intention. At the same time, the research results also confirm that interpersonal conflict affects counterproductive behavior and turnover intention. Moreover, interpersonal conflict mediates the effect of AI awareness on counterproductive behavior and turnover intention, and the moderating roles of perceived organizational support and competitive psychological climate has been confirmed.

Sample data was only collected at a few Vietnamese enterprises in 6 fields with the highest level of application which are e-commerce, transportation and logistics, education, real estate, finance and agriculture, which may be limiting generalizability of research results. Future studies could include data from enterprises in different sectors or focus on a specific sector.

The authors offer several significant implications to reduce counterproductive work behavior and turnover intention in enterprises, such as by paying attention that the penetration and spread of AI or other smart technologies is inevitable in the future, ensuring make sure support from organization is available for the employees and creating a working environment of integrity and honesty in all situations based on trust, respect and fairness.

The study developed and verified a moderated mediated model on the relationship between AI awareness and counterproductive work behavior, turnover intention. The authors confirmed the mediating role of interpersonal conflict and the moderating role of perceived organizational support and competitive psychological climate in the relationship among AI awareness and counterproductive work behavior, turnover intention.
