Previous researchers study the presence of anomalies in the stock market but very few studies identify the causes that generate anomalies. This study tests the efficient market hypothesis in the context of prospect theory. The main aim of this study is to examine the effect of behavioural factors on different classes of anomalies. Further, the paper investigates the differential effect of prospects components on different classes of anomalies. Data collected from 324 real individual investors of Pakistani Stock Exchange. Structural equation modelling was used to test the hypothesised model using smart PLS 3.0. The results show that mental accounting has a positive significant effect on all anomalies. In short, investors use their own mental account in their decision-making. Loss aversion has a positive significant effect on technical anomalies and regret has a positive significant effect on fundamental anomalies. However, self-control does not have a significant effect on technical and calendar anomalies.
以往的研究者研究了股票市场中异常的存在,但很少有研究确定产生异常的原因。本研究在前景理论的背景下检验了有效市场假说。本研究的主要目的是研究行为因素对不同类型异常的影响。此外,本文还研究了远景分量对不同类型异常的不同影响。数据收集自巴基斯坦证券交易所的324名真实个人投资者。采用结构方程模型,使用智能PLS 3.0对假设模型进行检验。结果表明,心理会计对所有异常都有显著的正向影响。简而言之,投资者在决策时使用自己的心理账户。损失厌恶对技术异常有正显著影响,后悔对基本面异常有正显著影响。然而,自我控制对技术和日历异常没有显著影响。

Factors affecting buyers' trust in e-commerce in Palestine 影响巴勒斯坦买家对电子商务信任的因素
Pub Date : 2019-06-17 DOI: 10.1504/MEJM.2019.10017834

Electronic commerce (e-commerce) is relatively a new concept and research topic in developing countries including Palestine. In this form of commerce, the first impression that users create about an organisation is often based on the organisation's website's trustworthiness. This has motivated many researchers to investigate the factors that influence buyers' trust in such websites. The main purpose of this study is to investigate the potential factors affecting buyers' trust in e-commerce in Palestine. More specifically, the study embraces a multi-dimensional construct of trust (integrity, benevolence, ability) rather than examining each single dimension of trustworthiness individually. In addition, the effect of independent variables including website design attitudes, reliability, privacy and security attitudes, customer satisfaction and governmental factors on e-commerce's trust dimensions have been mathematically investigated. To this end, relevant data from a random sample of 354 Palestinian citizens who have experienced the online shopping, or who have interest in online purchasing, were collected. Statistical analyses revealed significant effects of all independent variables except reliability on buyers' trust in e-commerce in Palestine. Also, four linear regression models relating the independent variables with e-commerce's trust and its three dimensions (integrity, benevolence, ability) have been built and statistically validated.
在包括巴勒斯坦在内的发展中国家,电子商务是一个相对较新的概念和研究课题。在这种商业形式中,用户对一个组织的第一印象通常是基于该组织网站的可信度。这促使许多研究人员调查影响买家对此类网站信任的因素。本研究的主要目的是调查影响巴勒斯坦买家对电子商务信任的潜在因素。更具体地说,该研究包含了信任的多维结构(正直、仁慈、能力),而不是单独检查可信度的每个单一维度。此外,从数学上考察了网站设计态度、可靠性、隐私和安全态度、客户满意度和政府因素等自变量对电子商务信任维度的影响。为此目的,从354名经历过网上购物或对网上购物感兴趣的巴勒斯坦公民随机抽样中收集了相关数据。统计分析显示,除可靠性外,所有自变量对巴勒斯坦电子商务买家信任的影响均显著。建立了自变量与电子商务信任及其诚信、仁爱、能力三个维度的线性回归模型,并进行了统计验证。

This paper aims to identify customer relationship management components (call centre, service centre, and data mining) and their role in influencing customer retention through customer satisfaction in telecom industry. The study used a descriptive analytical method to answer the questions of the study. A questionnaire was used as a tool for data collection. The sample consists of 317 Y-Telecoms' subscribers. The study showed that there is an effect of CRM system components in achieving customer retention. Data mining is deemed the highest component of the technological elements in CRM, which contributed in achieving customer retention. However, the call centre is the lowest component, which requires more work and development. Customer satisfaction - the intervening variable - showed no correlation with customer retention. The study recommends the call centre staff to improve their communication skills and focusing on data mining process to make better services for clients and employ them in marketing to target customers individually.
本文旨在识别电信行业客户关系管理组件(呼叫中心、服务中心和数据挖掘)及其通过客户满意度影响客户保留的作用。本研究采用描述性分析方法来回答本研究的问题。问卷被用作数据收集的工具。样本包括317名y - telecom的用户。研究表明,CRM系统组件在实现客户保留方面具有一定的作用。数据挖掘被认为是CRM中技术元素的最高组成部分,它有助于实现客户保留。然而,呼叫中心是最低级的组件,需要更多的工作和开发。作为中介变量的顾客满意度与顾客保留率没有相关性。该研究建议呼叫中心员工提高沟通技巧,注重数据挖掘过程,为客户提供更好的服务,并利用他们进行营销,以个别目标客户。

The aim of this research is to examine the influence of transformational leadership (TL) on innovative work behaviour (IWB) and mediating effect of teacher's self-efficacy (TSE) and innovative climate (IC). A quantitative research paradigm was employed using a questionnaire survey method; the data was collected from 112 academicians of engineering schools in the universities. Data has been analysed through Pearson correlation and linear regression tests. Results revealed that a positive relationship between transformational leadership and innovative work behaviour. The ordinary least square (OLS) method results supported the relationship between transformational leadership and innovative work behaviour via one mediating variable teachers self efficacy, but innovative climate does not mediates the relationship between transformational leadership and innovative work behaviour. The study contributes to the current knowledge regarding transformational leadership (TL) on innovative work behaviour (IWB) and mediating effect of teachers self efficacy (TSE) and innovative climate (IC).

Advertising plays an important role in the marketing strategy and a considerable amount of budgets has been allocated for advertising every year. However, the proportion of advertisement campaign achievements to those designated for their design, or in other words, its efficiency, is questionable. This study was conducted to assess the efficiency of the food industry's advertising brands using data envelopment analysis (DEA). The duration of the campaign and budget as input and brand familiarity, attractiveness of implementation and sale were used as an output for the evaluation. The results of the study indicated that there are inefficiencies in this industry, thus in an attempt to improve the situation of the advertising efficiency, some solutions was provided to managers. Also, the most important variables affecting the efficiency of the food industry was identified by sensitivity analysis.
广告在营销策略中扮演着重要的角色,每年都有相当多的预算被分配给广告。然而,广告活动的成果占其设计成果的比例,或者换句话说,其效率是值得怀疑的。本研究使用数据包络分析(DEA)来评估食品行业广告品牌的效率。活动的持续时间和预算作为输入,品牌熟悉度,实施和销售的吸引力被用作评估的输出。研究结果表明,该行业存在效率低下的问题,因此,为了改善广告效率的状况,本文为管理者提供了一些解决方案。此外,通过敏感性分析确定了影响食品工业效率的最重要变量。

This paper investigates the relationship between firm's financing choices, taxation benefits and investment in Pakistani listed firms. We apply the system generalised method of moments regression estimation on a sample of firms listed on Pakistan Stock Exchange during the period from 2001-2014. Our findings are that there is a positive relationship between leverage and investment accruing from the use of tax shield benefits which also are positively associated with the firm-level investment. Equity is also positively related to investment but the effect of leverage is more pronounced than equity. We also find that the positive relation between leverage and investment is stronger for firms with a medium level of debt, consistent with the trade-off theory argument of the existence of an optimal level of debt. Our results support the hypothesis that firms utilise debt to supplement investment in circumstances where alternate mechanisms of finance are not well developed.
本文研究了巴基斯坦上市公司融资选择、税收优惠与投资之间的关系。我们将矩回归估计的系统广义方法应用于2001-2014年巴基斯坦证券交易所上市公司的样本。我们的研究结果是,杠杆和投资之间存在正相关关系,这些投资来自于使用税盾利益,这也与公司层面的投资呈正相关。股权也与投资呈正相关,但杠杆的影响比股权更明显。我们还发现,对于负债水平中等的企业,杠杆与投资之间的正相关关系更强,这与存在最优负债水平的权衡理论相一致。我们的研究结果支持这样的假设,即在替代融资机制不发达的情况下,企业利用债务来补充投资。

This study aims to determine the moderator role of the organisational justice and the ethical climate perceived by employees on job satisfaction, intention on ceasing the employment, and performance levels. In the light of this aim, questionnaires were used by using the convenience sampling method with 347 employees in Istanbul and Afyonkarahisar. The performance levels of 347 employees were evaluated by their administrators. The results of the questionnaires and the performance evaluation were analysed and interpreted by using descriptive analyses and regression analyses. According to the results obtained in the analyses, the perceived organisational justice was high when the job satisfaction, and performance levels were high when the perceived ethical climate was high; however, there were no significant relations between the turnover intention.

本研究旨在探讨组织公平感和员工感知的道德氛围对工作满意度、离职意向和绩效水平的调节作用。针对这一目的,采用方便抽样法对伊斯坦布尔和Afyonkarahisar的347名员工进行问卷调查。347名员工的绩效水平由他们的管理者评估。采用描述性分析和回归分析对问卷调查结果和绩效评价结果进行分析和解释。分析结果表明,工作满意度高时,组织公平感高;道德氛围高时,绩效水平高;而离职意向与离职意向之间的关系不显著。研究发现,感知伦理氛围仅对感知组织公正、工作满意度和绩效之间的关系有调节作用。

In the light of this aim, questionnaires were used by using the convenience sampling method with 347 employees in Istanbul and Afyonkarahisar. The performance levels of 347 employees were evaluated by their administrators. The results of the questionnaires and the performance evaluation were analysed and interpreted by using descriptive analyses and regression analyses. According to the results obtained in the analyses, the perceived organisational justice was high when the job satisfaction, and performance levels were high when the perceived ethical climate was high; however, there were no significant relations between the turnover intention. It was determined that the perceived ethical climate had a moderator effect only in the relation between the perceived organisational justice, job satisfaction and performance.","PeriodicalId":123919,"journal":{"name":"Middle East J. of Management","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130042680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The uncertainty and volatility of oil prices and the rise of political uncertainty in the Middle East Region have shifted the ground beneath the Gulf Cooperation Council (GCC) economies in recent years. The traditional planning methods are strategically blind and inherently short sighted when used by firms under uncertainty. This study provides concepts, analytic tools, and examples of the four levels of uncertainty. The study draws a parallel between the uncertainty in chess game and business and tailored chess principles, processes, strategies and tactics to be used by businesses under uncertainty situations. This study contributes to current knowledge of using chess as metaphor to describe business, finding a connection to the dynamics of chess given the use of its principles, strategy and tactics.
近年来,石油价格的不确定性和波动性以及中东地区政治不确定性的上升已经改变了海湾合作委员会(GCC)经济体的基础。传统的规划方法在不确定的情况下使用时具有战略盲目性和固有的短视性。本研究提供了四个不确定性层次的概念、分析工具和例子。该研究将国际象棋和商业中的不确定性与企业在不确定情况下使用的量身定制的国际象棋原则、流程、战略和战术进行了比较。这项研究有助于当前使用国际象棋作为隐喻来描述商业的知识,找到与国际象棋动态的联系,并赋予其原则,战略和战术的使用。
