: Purpose: This article examines the relationship between oil price volatility, exchange rate, interest rate, and the stock market in the GCC countries. Design/Methodology/Approach: We used an annual data set from January 2006 to December 2015. Then, we explore the feedback between this relation by one-step generalized method of moments (GMM) system estimator and panel vector autoregressive (PVAR) model. Findings: We find that the increased of the interest rates leads to increased oil price, which implies that this result is completely normal since the low-interest rates, decrease in oil prices. Practical Implications: The study provides a significant contribution as its findings can give policymakers, regulators and investor. Moreover, this study can help import and export oil. In fact, should be reformed energy taxation to encourage households and businesses to protect themselves against future oil price increases and facilitate the transition of energy. Originality/Value: A harmonized action at the European level would make the reform of energy taxation a virtuous tool to reduce public deficits.
:目的:本文探讨了海湾合作委员会国家的石油价格波动、汇率、利率和股票市场之间的关系。设计/方法/途径:我们使用了 2006 年 1 月至 2015 年 12 月的年度数据集。然后,我们通过一步广义矩法(GMM)系统估计法和面板向量自回归(PVAR)模型探讨了这种关系之间的反馈。研究结果我们发现,利率上升会导致石油价格上涨,这意味着这一结果是完全正常的,因为低利率会导致石油价格下降。实际意义:本研究具有重要意义,因为其结论可以为政策制定者、监管者和投资者提供参考。此外,这项研究还有助于石油进出口。事实上,应改革能源税收,鼓励家庭和企业保护自己免受未来油价上涨的影响,促进能源转型。原创性/价值:欧洲层面的统一行动将使能源税改革成为减少公共赤字的良性工具。

: Purpose: To determine the influence of ethical leadership and sustainable leadership on sustainable performance in medium-sized companies. In addition, this research evaluates the moderating role of gender in this relationship. Design/Methodology/Approach: Data from medium-sized companies in Guayaquil, Quito, Manabí, El Oro, and Azuay in Ecuador were used. Using structural equation modeling, the influence of ethical and sustainable leadership on sustainable performance and the moderating role of gender were analyzed. Findings: The results show that ethical leadership has a significant negative influence on sustainable performance and sustainable leadership has a significant positive influence on sustainable performance. Additionally, the moderation of gender in the relationship between sustainable leadership and sustainable performance is verified. Practical implications: This study proposes a new model considering three constructs: ethical leadership, sustainable leadership and sustainable performance, which will serve for future research on these topics. Originality/value: With these findings, new knowledge is contributed to both the scientific community and business management.

Ownership Structure, Board Characteristics, and Firm Diversification: Evidence from an Emerging Country 所有权结构、董事会特征与企业多元化:来自新兴国家的证据
Pub Date : 2023-11-01 DOI: 10.35808/ijeba/820
Manel Gharbi, Anis Jarboui
: Purpose: The purpose of this paper is to argue the effect of ownership structure and board of directors on firm diversification . Design/Methodology/Approach: The data is gathered via a questionnaire administered to 111 managers from Tunisian in small-and medium-sized companies. To analyze collected data we used SPSS and Amos graphics software. Hypotheses were tested using the regression analysis technique. The study gives empirical information on the relationship between cognitive variables and strategic decision-making, specifically diversification. Findings: The findings reached following the logistic regression prove to reveal well that companies whose executives a certain capital share do not count as actually diversified firms. Thus, the assumption stipulating that the directors’ shareholding is negatively associated with diversification seems verified. Still, the results attained prove to demonstrate that family structure is negatively related to diversification policy. In addition, company size and leverage appear to not affect diversification decisions. Yet, performance turns out to have a positive and significant relationship with such a decision. Research implications : Although the Tunisian corporate governance reform concerning the independent director system which is mandatory only for newly-listed companies is successful, the regulatory authority should require all listed companies to appoint independent directors to further enhance the Tunisian corporate governance. Future research could include other proxies of corporate governance and ownership structure such as board diversity and meetings, audit committee and managerial ownership, etc. Originality/Value: First, unlike most of the previous literature on emergent countries, this study examines the effects of corporate governance mechanisms on firm diversification in Tunisia. Second, while several studies used a single indicator of firm diversification, this study examines both accounting-based and market-based firm diversification. Third, this study addresses the endogeneity issue between corporate governance factors and firm diversification, a strategic decision.
:目的:本文旨在论证所有权结构和董事会对公司多元化的影响。设计/方法/途径:本文通过对 111 名突尼斯中小型公司经理进行问卷调查来收集数据。为了分析收集到的数据,我们使用了 SPSS 和 Amos 图形软件。使用回归分析技术对假设进行了检验。本研究提供了认知变量与战略决策(特别是多元化)之间关系的实证信息。研究结果根据逻辑回归得出的结果证明,高管占一定资本份额的公司并不算是真正的多元化公司。因此,董事持股与多元化负相关的假设似乎得到了验证。尽管如此,研究结果还是证明,家族结构与多元化政策呈负相关。此外,公司规模和杠杆似乎并不影响多元化决策。然而,公司业绩却与多元化决策有显著的正相关关系。研究意义 :尽管突尼斯公司治理改革中有关独立董事制度(仅对新上市公司具有强制性)的改革是成功的,但监管机构应要求所有上市公司任命独立董事,以进一步加强突尼斯的公司治理。未来的研究可以包括公司治理和所有权结构的其他代用指标,如董事会多样性和会议、审计委员会和管理层所有权等。原创性/价值:首先,与以往大多数关于新兴国家的文献不同,本研究探讨了公司治理机制对突尼斯公司多元化的影响。其次,一些研究使用了企业多元化的单一指标,而本研究同时考察了基于会计和基于市场的企业多元化。第三,本研究解决了公司治理因素与公司多元化这一战略决策之间的内生性问题。

: Purpose: The aim of this study is to investigate the relationship between the price of crude oil and the BRICS countries 04/01/2016 to 05/01/2023, by analyzing the spillover effects and connectedness using the quantile VAR approach. Design/Methodology/Approach: Researchers focused on three quantiles - median, high, and low to capture the connectedness. Findings: The results show first, that there is higher total connectedness in the bearish and bullish market conditions compared with normal conditions. Moreover, the degree of connectedness is even stronger during periods of crises such the case during the Covid-19 pandemic and the Russian-Ukrainian war. This shows that under extreme market conditions, the strength of the connectedness increases with the size of the shock, suggesting a symmetric relationship. Practical implications: The frequency connectedness is divided into high and low-frequency and it is discovered that the short-term TCI had a greater impact on the total TCI than the long-term TCI. Originality value: These findings can be valuable for both international investors and policy makers.
:目的:本研究旨在通过使用量化 VAR 方法分析溢出效应和关联性,研究 2016 年 1 月 4 日至 2023 年 1 月 5 日原油价格与金砖国家之间的关系。设计/方法/途径:研究人员侧重于中位数、高位数和低位数这三个量级来捕捉关联性。研究结果:结果表明:首先,与正常情况相比,熊市和牛市条件下的总关联度更高。此外,在危机时期,如科维德-19 大流行病和俄乌战争期间,关联度更高。这表明,在极端市场条件下,关联性的强度会随着冲击的大小而增加,这表明存在一种对称关系。实际意义:频率连通性分为高频和低频,发现短期 TCI 对总 TCI 的影响大于长期 TCI。原创性价值:这些发现对国际投资者和政策制定者都很有价值。

The present research study is focused on the analysis of the role of situational leadership in the context of small and medium-sized enterprise management. The main purpose of this research is to examine and to critically evaluate the use of different situational leadership styles in the management of SMEs. This study has sought to review leader obligations and the evolution of these leadership styles in SME management. The study has intended to provide the fundamental empirical evaluation of the role played by situational leadership in SME management. The sample for the present research has been identified from the population of registered trucking companies in Durban. A sample has been drawn from the SMEs within the registered trucking companies, using convenient sampling techniques and methods.The findings of this research have shown the positive impact that situational leadership theory has in SME management. In fact, SME owners and managers will be inspired to understand the managerial role of the appropriateness behavioural style in the contextual business situations. Also, the study recommended that owners and leaders of SMEs should ameliorate leader sovereignty and follower skills, as these often interact in predicting poor follower performance and attitudinal responses. In addition, the present study has provided the tools necessary for SME owners and managers, to guide the improvement and effectiveness of personal leadership.
本研究的重点是分析情境领导在中小企业管理中的作用。本研究的主要目的是检验和批判性地评估在中小企业管理中不同情境领导风格的使用。本研究试图回顾领导义务和这些领导风格在中小企业管理中的演变。本研究旨在为情境领导在中小企业管理中的作用提供基本的实证评价。本研究的样本是从德班注册卡车运输公司的人口中确定的。采用便捷的抽样技术和方法,对注册货运公司内的中小企业进行抽样。本研究的结果显示情境领导理论对中小企业管理的正面影响。事实上,中小企业主和管理者将受到启发,了解适当的行为风格在上下文业务情况下的管理作用。此外,该研究还建议中小企业的所有者和领导者应该改善领导者主权和追随者技能,因为它们经常在预测糟糕的追随者绩效和态度反应方面相互作用。此外,本研究为中小企业主和管理者提供了必要的工具,以指导个人领导的改进和有效性。

The literature widely covered engagement from different perspectives and how it is affected by different job resources and job demands. This study tackles the effect of job resources including the hybrid-working model, manager coaching, and other resources on engagement. Even though job resources were extensively examined in the literature; this paper introduces the hybrid working model as a job resource and the long-term assignment as a job demand affecting employee engagement.This study aimed to investigate the effect of the hybrid working model, manager coaching and development plans under long-term assignment conditions on engagement using a cross-sectional questionnaire. Respondents were engineers involved in a long-term assignment (long duration in the same project). The results revealed that job resources had a statistical significance as well as a positive relationship with engagement, while LTA had a statistical significance as well as a negative moderating effect on the relationship between job resources and engagement.The study findings suggested that the relationship between job resources and engagement is negatively moderated by working on long-term assignments.
文献广泛地从不同的角度涵盖敬业度,以及不同的工作资源和工作需求对敬业度的影响。本研究探讨了工作资源(包括混合工作模式、经理培训和其他资源)对员工敬业度的影响。尽管工作资源在文献中被广泛研究;本文介绍了混合工作模式作为一种工作资源,长期任务作为一种工作需求影响员工敬业度。本研究采用横断面问卷调查的方法,探讨长期外派条件下混合工作模式、经理培训和发展计划对员工敬业度的影响。受访者是参与长期任务的工程师(在同一个项目中持续时间很长)。结果表明,工作资源对员工敬业度具有显著的正向影响,而LTA对工作资源对员工敬业度具有显著的负向调节作用。研究结果表明,工作资源和敬业度之间的关系被长期任务负向调节。

Black Swan Theory of Events and the Impact to Hospitality Operators: Literature Review and Proposed Analysis 事件的黑天鹅理论和对酒店经营者的影响:文献综述和建议分析
Pub Date : 2023-08-11 DOI: 10.5430/ijba.v14n3p12
S. Kent
The Black Swan theory of events is an incident that deviates beyond what is normally expected of a situation and is extremely difficult to predict (Talib, 2007). Black Swan events impact the hospitality industry in many ways. Weather, widespread illness, civil unrest, terrorism, and loss of utilities are out of the immediate control of the industry’s participants but impact their results. Occurrences at the property/corporate level can also impact performance in ways such as: food contaminants impacting restaurants, cruise ships losing power, running a ground, or sinking, experiencing a widespread Nora virus, hotels face fires, strikes, data breaches, boycotts, as well as events such as amusement parks having ride fatalities and animal welfare protests, etc. All of these events are quickly spread by multiple news sources, and consumers are able to search quickly using Google or other search engines to get more details.Previous studies have looked at the aftereffects of exogenous—or self-inflicted— events, and how management teams reacted or did not react and the impact to operating results (Kosova & Enz, 2012). However, there is a paucity of academic analysis of Black Swan events to determine whether there is a way to reduce the impact.
事件的黑天鹅理论是一种事件,它偏离了通常对情况的预期,并且极难预测(Talib, 2007)。黑天鹅事件在许多方面影响着酒店业。天气、广泛的疾病、内乱、恐怖主义和公用事业损失都不在行业参与者的直接控制范围内,但会影响他们的业绩。物业/公司层面的事件也会以以下方式影响性能:食品污染物影响餐馆,游轮失去动力,运行地面或沉没,经历广泛的诺拉病毒,酒店面临火灾,罢工,数据泄露,抵制,以及游乐园发生游乐事故和动物福利抗议等事件。所有这些事件都通过多个新闻来源迅速传播,消费者可以使用谷歌或其他搜索引擎快速搜索以获得更多细节。以前的研究着眼于外因或自我造成的事件的后果,以及管理团队如何反应或不反应以及对经营结果的影响(Kosova & Enz, 2012)。然而,缺乏对黑天鹅事件的学术分析,以确定是否有办法减少其影响。

The purpose of this article was to map the most likely scenario for the year 2023, given the economic prospects in the world, and to project tendencies. To this end, a documental analysis was carried out based on studies made available by organizations and institutes specialized in global economic analysis. The applied method was the exploratory and the technical procedure was the bibliographic and descriptive, using a quali-quantitative technique to analyse and qualify the data. To operationalize the research, the material obtained was manipulated for subsequent tabulation and construction of graphics and tables using the Microsoft Excel application. Among the main elements used to identify the economic impacts, we can quote: (i) the COVID-19 pandemic, (ii) the main tendencies of the economy in the post-pandemic world, (iii) the economic policies adopted by countries in combating to the crisis, and (iv) the behaviour of wage dynamics in this context. The results showed that the economic crisis aggravated by the COVID-19 pandemic caused a global economic recession, severely affecting the cost of living. In the field of tendencies, there was the expectation of low economic growth and restrictive policies that are causing an increase in interest rates. In the labour market, the outlook is for a low supply of workforce with repercussions on wage dynamics, which should remain below the values practiced before the health crisis. The possible solution will depend on the willingness of the countries to promote cooperation to provide priority assistance to the most vulnerable classes and the ability to stabilize prices, avoiding greater pressure on inflation and interest rates, with a direct impact on wages.
这篇文章的目的是绘制2023年最有可能的情景,考虑到世界经济前景,并预测趋势。为此目的,根据专门从事全球经济分析的组织和研究所提供的研究,进行了文献分析。应用的方法是探索性的,技术步骤是书目和描述,使用定性定量技术对数据进行分析和鉴定。为了使研究可操作,使用Microsoft Excel应用程序对获得的材料进行了操作,以便随后制表和构建图形和表格。在用于确定经济影响的主要因素中,我们可以引用:(i) COVID-19大流行,(ii)大流行后世界经济的主要趋势,(iii)各国在应对危机中采取的经济政策,以及(iv)在此背景下的工资动态行为。结果显示,新冠肺炎疫情加剧的经济危机导致全球经济衰退,严重影响了生活成本。在趋势方面,人们预期经济增长会很低,限制性政策正在导致利率上升。在劳动力市场,前景是劳动力供应不足,这将对工资动态产生影响,工资应保持在卫生危机前的水平以下。可能的解决办法将取决于各国是否愿意促进合作,向最脆弱的阶层提供优先援助,以及稳定价格的能力,从而避免通货膨胀和利率承受更大的压力,从而直接影响到工资。
