The price clustering behavior is becoming a core part of the market efficiency theory especially with the development of trading strategies and the occurrence of major and unprecedented shocks which have led to severe inquiry regarding asset price dynamics and their distribution. However, research on emerging stock market is scant. The study contributes to the literature on price clustering by investigating an active emerging stock market, the Muscat stock market one of the Arabian Gulf Markets.

This research adopts the artificial intelligence technique and other statistical estimation procedure in understanding the price clustering patterns in Muscat stock market and their main determinants.

The findings reveal that stock prices are marked by clustering behavior as commonly highlighted in the previous studies. However, we found strong evidence of price preferences to cluster on numbers closer to zero than to one. We also show that the nature of firm’s activity matters for price clustering behavior. In addition, firms with traded bonds in Oman market experienced a substantial less stock price clustering than other firms. Clustered stock prices are more likely to have higher prices and higher volatility of price. Finally, clustering raised when the market became highly uncertain during the Covid-19 crisis especially for the financial firms.

This study provides novel results on price clustering literature especially for an active emerging market and during the Covid-19 pandemic crisis.

This paper aims to examine the extent of price clustering in a selection of Islamic stocks listed in Indonesia, Malaysia and Pakistan and also investigates the determinants of the phenomenon at the firm level.

The author test the uniformity of price distribution in the selected securities. Then, the determinants of price clustering were investigated through multivariate analysis based on a binary logistic regression model. Following the arguments of Narayan et al. (2011), who emphasize the importance of considering firm heterogeneity when studying the phenomenon, the author conducts the empirical study at the firm level.

The evidence indicates that Islamic stocks show a mild level of price clustering. Only half of the stocks under analysis rejected the uniformity test in the distribution of prices. In these cases, investors exhibited a preference for prices ending at zero and five. The evidence does not confirm the cultural clustering theories. Price clustering is found to be positively associated with price level and relative bid-ask spread. Overall, the negotiation hypothesis, which predicts that investors prefer round prices to minimize the costs associated with negotiations, best explains most of our results.

The existence of price clustering is difficult to reconcile with the prediction of the efficient market hypothesis that prices should follow a random walk. Moreover, the evidence indicates that Muslim investors share a preference for round prices in some settings, under the assumption that Islamic stocks are mostly traded by Muslim investors.

To the author’s best knowledge, this is the first study to address the subject of price clustering in Islamic stocks.

The aim of this study is to determine the effect of ethical leadership (EL) on individual ambidexterity (IA). Equity sensitivity (ES) was proposed as an underlying mechanism between EL and ambidexterity. Openness to experience (OTE) was hypothesized to strengthen the effect of EL on IA.

Data were collected, using a cross-sectional survey design, from employees working in Software Houses in Pakistan using multistage sampling. A usable sample of 255 was subjected to analysis in a two-step structural equation modelling.

The empirical findings revealed that EL has a positive effect on IA. ES partially mediated between EL and IA. OTE strengthens the impact of EL on IA.

This study carries some implications for practitioners, and in particular it provides a clear direction to the management who exhibits EL characteristics. Ethical leaders encourage their followers to explore new things, to behave more innovatively at work and to take the risk in implementing and introducing new ideas.

This study highlights that EL should establish a positive work environment in which employees have a comfortable feeling when applying their explorative and exploitative activities to their work.

This study investigates critical linkages between EL and IA. Given the importance of IA, results provide novel guidance regarding EL style and the significance of equity in workplace. Recruitment decisions will also be guided by choosing those who have an open personality orientation in the workplace.

In the 21st century, spirituality is becoming an interesting phenomenon in the workplace and has been discussed by academicians, researchers, and practitioners alike. This growing knowledge offers important insights and calls for conceptual and empirical studies on workplace spirituality. Accordingly, the current research aims to examine how ethical leadership (EL) helps to foster workplace spirituality and job satisfaction (JS) in the information technology (IT) industry. Additionally, it investigates the mediating role of workplace spirituality and moderating role of self-efficacy (SE) in the relationship between EL and JS.

Using a cross-sectional design, the data were collected from 268 employees in the IT industry and analyzed on SmartPLS 3.2 using structural equation modeling.

The findings indicated that EL promotes a sense of spirituality and increases JS. Additionally, results suggested that workplace spirituality partially mediates, and SE moderates the relationship between EL and JS.

The results suggest that the top executives should work on identifying and developing ethical qualities to promote a sense of meaningfulness (workplace spirituality) and increase JS.

The research provides an important contribution to the academic literature by exploring the role of EL in fostering spirituality among employees and the moderation of SE on the relationship between EL and JS in the services industry.

This study aims to investigate the association between cognitive moral development (CMD) and unethical pro-organizational behaviour (UPB) by taking purchasing employees as research subjects. The moderating effect of perceived leader’s UPB is also explored.

Data were collected through a two-stage questionnaire survey on purchasing employees in companies across a spectrum of industries in Taiwan, and 492 purchasing employees were analysed in the study.

Research findings reveal that employees at the conventional level of CMD are more likely to conduct UPB than those at the pre-conventional and post-conventional levels. Perceived leader’s UPB will moderate the association between CMD and UPB. Employees’ UPB is strongly associated with their CMD when they perceive their leaders as being likely to perform UPB.

Although a variety of factors influencing UPB have been proposed in the literature, none of them have analysed the association between CMD and UPB. However, CMD is one important factor affecting ethical decision-making. The present study can promote further understanding of the role of CMD in UPB and contribute to a growing body of research on CMD and UPB.

The purpose of this paper is to investigate how perceived organisational support (POS) enhances the well-being of migrant workers in Taiwan by strengthening their resilience. In addition, the moderating role of ethical leadership in this association was investigated based on the conservation of resources (COR) theory.

The data were gathered from migrant workers from Southeast Asian countries, including Vietnam, Indonesia, Thailand and the Philippines with structured questionnaires during the COVID-19 pandemic. A total of 420 samples were analysed by testing the mediation and moderation model.

The results showed a significant effect of POS on migrant workers' well-being in Taiwan through the mediating role of resilience. Moreover, ethical leadership moderated the effect of POS on employee resilience and work well-being.

The sample was restricted to Southeast Asian migrant workers who were employed in industrial sectors in Taiwan. The study considered several demographic variables, including language proficiency, nationality and marital status, which could result in cultural and language biases. A cross-sectional design and self-reported data were utilised, which could potentially create common method variance biases and inflated correlations across the research variables.

The present study may be helpful to organisational leaders in the process of designing approaches for promoting a people-oriented and harmonious workplace. Employee well-being can be strengthened through employee resilience (individual factors), as well as POS and ethical leadership (organisational factors).

This study supports the use of COR theory in confirming POS as a resource that strengthens employees' resilience capabilities and work well-being. Employee resilience serves as a mediator of the relationship between POS and employee well-being. Ethical leadership serves as a moderator in strengthening the relationships between POS and employee resilience, as well as between POS and work well-being of migrant workers.

The purpose of this study is to analyze the effect of wine tourism on the economic, social and environmental performance, i.e. the sustainable performance, of Spanish wineries. In addition, age, size and membership in the protected designation of origin are introduced as control variables to increase the precision of the cause-effect relationships analyzed.

A conceptual model is proposed, which is tested by means of structural equation modeling based on data from a survey of 202 Spanish wineries.

The results indicate the existence of a positive and significant link between wine tourism activities and the three performance typologies analyzed in the Spanish wine context.

The study contributes to the academic literature on wine tourism in a remarkable way, as, to the best of the authors’ knowledge, there is no previous literature that has addressed the effect of wine tourism on the sustainable performance of Spanish wineries, making the study useful for both academics and wine professionals who are considering the implementation or development of this typology of tourism in their facilities.

The COVID-19 pandemic has caused havoc on a global scale for supply chains, which put forward higher demand for organizations to reassess their global supply chain strategy and improve supply chain sustainability. The purpose of this paper is to understand how leader's paradoxical cognition affect supply chain sustainability.

This study conceptualizes a research model grounded in upper echelons theory and propose a chain-mediating model under the moderating effect of big data analytics. Using PLS-SEM method, we test the hypotheses using survey data collected from supply chain managers or leaders of the supply chain team from 193 firms.

The results indicate that supply chain ambidexterity and organizational learning play a mediating role in the relationship between leaders' paradoxical cognition on supply chain sustainability, respectively, and these two variables have a chain-mediating role in the relationship above. In addition, the big data analytics negatively moderates the relationship between leader's paradoxical cognition and organizational learning, and further moderates our chain mediating model.

This research initiatively focuses on the micro-foundations of supply chain sustainability from managerial cognition and firstly provides empirical evidence about the impact of leader's paradoxical cognition on supply chain sustainability.

The success of projects is a major challenge for information technology (IT) project-based businesses (PBOs). Employees' negative emotions (NE) disrupt the employees' usual work activities by creating obstacles to routine operations. Organizations should take steps to lessen these NE. The current study assessed the mediating role of NE and the moderating influence of employee mindfulness in the association between despotic leadership (DL) and IT project success (PS).

Time-lagged data were collected from 341 employees working in various IT-based project organizations in Pakistan using purposive sampling.

Results were consistent with the authors' hypothesized framework, as DL increases employees' NE, which in turn negatively affects IT PS. In addition, mindfulness plays a buffering role in mitigating the damaging impact of DL on NE.

Previous researchers focused on the positive aspects of leadership and its influence on PS and paid limited attention to the dark leadership style. The authors' study's findings help understand how project-based organizations can reduce employees' NE.

This study, based on social exchange theory, aims to explore the association between appreciative leadership and employees' helping behaviors by investigating the mediation role of emotional reactions (pride, anxiety), and choosing organizational trust as a boundary condition between appreciative leadership and helping behaviors.

A total sample of 285 reliable questionnaires were collected in three time lags from employees working in the Pakistani education and banking sectors. PROCESS macro using SPSS and AMOS are employed for data analyses of the proposed model.

The findings reveal that appreciative leadership has positive impacts on employees' helping behaviors and emotional reactions (pride, anxiety) mediate the relationship of appreciative leadership and employees' helping behaviors. In addition, the results show that high organizational trust strengthens the positive relationship between appreciative leadership and employees' helping behaviors.

This research has provided empirical proof between the relationship of appreciative leadership and helping behaviors and the findings are of great significance for managers, employees, and organizations. The study proposes that leaders should have appreciative behavior while treating their subordinates. Moreover, it is revealed that the role of organizational trust should be given more attention and importance because it is a factor moderating the employees' helping behaviors.

The present study, among the first empirical efforts investigating the relationship between appreciative leadership and helping behaviors, organizational trust as a moderator, enriches the existing academic literature of and provides worthy insight into the research on appreciative leadership and helping behaviors.
