Abstract
Purpose
This study examines the extreme quantile connectedness and spillovers between West Texas Intermediate (WTI) crude oil futures and ten Vietnamese stock market sectors. Knowledge of such links is important to both investors and policymakers in understanding the transmission of shocks across markets.
Design/methodology/approach
The authors employ the extreme quantile connectedness methodology of Ando et al. (2022).
Findings
Initial results show that the size of spillovers is higher during bearish markets than bullish markets and under major financial, political, energy and pandemic events. The oil market is a net receiver of spillovers during downward markets and net contributors during upward markets. The banking sector is a net contributor of spillovers, whereas consumer discretionary and consumer staples are net receivers for different quantiles. The role of the remaining sectors as net receivers/contributors is sensitive to the quantiles. Oil has a large spillover effect on the electricity sector for all quantiles. Comparing all crises, oil offers the best hedging effectiveness to the Vietnamese sector during the coronavirus disease 2019 (COVID-19) crisis. Moreover, oil was a cheap hedge asset during oil crises. Finally, oil provides the highest hedging effectiveness for healthcare during the global financial crisis (GFC) and consumer staples during the European debt crisis (EDC), oil crisis and COVID-19.
Originality/value
Acknowledging the presence of heterogeneity in the relation between oil and economic sectors under different market conditions, this study is the first to examine the extreme quantile connectedness between oil and Vietnamese sectors.

Abstract
Purpose
Customer incivility is a crucial issue that has multiple negative effects on organizations, especially in the hospitality industry. This study identified the antecedents of customer incivility and investigated its outcomes on frontline employees (FLEs) in the emerging market of Vietnam.
Design/methodology/approach
This study used a quantitative methodology featuring interviews with 476 FLEs who frequently experienced customer incivility in Vietnamese restaurants and hotels. The data were analyzed using structural equation modeling.
Findings
The findings demonstrated four antecedents of customer incivility (training/knowledge, FLE incivility, service orientation, and environment) and three outcomes (revenge motivation, service sabotage, and turnover intention), as well as the mediating role of revenge motivation.
Practical implications
Managers can establish and upgrade training lessons with different syllabi for numerous FLE groups to improve staff perceptions and enhance the organization’s service orientation and environment, which can support the minimization of revenge motivation, service sabotage, and turnover intention among frontline staff members.
Originality/value
This study highlights how impactful customer incivility is and how to eliminate it by clarifying its origins and effects in Vietnamese hotel and restaurant organizations.

Abstract
Purpose
Property developers identify the vital role of social media brand engagement (SMBE) in sustaining their businesses in competitive marketplaces, but it remains underexplored. This paper examines how SMBE mediates the effects of firm-generated content (FGC) and user-generated content (UGC) on brand trust, considering the moderating effects of social media influencer endorsement (SMIE) and self-image congruence (SIC) for luxury residential properties (LRPs).
Design/methodology/approach
Around 516 high-income homebuyers in Vietnam who shared information about LRP on social media were targeted to test the research model empirically. The primary data collected from paper-based surveys were analysed using SPSS 26 and AMOS 24.
Findings
Results indicate that FGC and UGC positively impact SMBE and consequently significantly affect brand trust. Further, results confirm the moderating roles of SMIE and SIC in the effects of FGC and UGC on SMBE.
Research limitations/implications
Data and sample size were limited to meet the generalisation from different nations and cross cultures.
Practical implications
The authors' findings suggest that marketers should apply the authors' integrated SMBE model to strengthen brand–consumer interactions and increase their sales revenue.
Originality/value
This study is the first in its application of the uses and gratifications theory and self-congruence theory to investigate how SMBE mediates the relationship between FGC and brand trust as well as between UGC and brand trust. Noticeably, this study makes a novel contribution as the first to quantitatively explore the moderating effects of SMIE and SIC in the authors' research model.

Abstract
Purpose
Based on the trait activation theory, the current study systematically integrates how autonomy interacts with proactivity to influence the relationship between ethical leadership style and employee creativity.
Design/methodology/approach
Using simple random sampling and questionnaires, a sample of 475 engineering employees of 3 leading telecommunication companies in Ghana were obtained. The analysis was done using structured equation modeling (SEM), using SmartPLS.
Findings
The results showed that ethical leadership style provides employees with job autonomy which facilitates individual creativity. Employee proactivity also moderates a positive relationship between autonomy and creativity such that high-proactive employees are well placed to produce more creative outcomes when given autonomy. At the individual level, personal characteristics determine the degree of creativity.
Practical implications
The current study implies that telecommunication companies should put in more efforts to train and encourage leaders to be ethical in leaders' dealings with employees and employees must be rewarded for taking initiative.
Originality/value
With a focus on the integrative approach from a developing economy, this work is novel in exploring how contextual and personal features impact creativity.
