Abstract This study investigates the conventional and Islamic equity market reaction towards terrorism events in Pakistan from 2009 to 2016 using OLS regression and GARCH (1, 1) models. The prospect theory and efficient market hypothesis are the relevant theories. Findings indicate that conventional and Islamic equity market reaction towards terrorism events is very short lived and markets recovers quickly. This study also documents the market reaction to terrorism events based on the target type, location and during the Islamic calendar months. The impact of different target types and different event locations on the conventional and Islamic equity markets varies. The equity markets in Pakistan responds negatively to the attacks on educational institutes and businesses whereas positively to attacks on armed forces’ facilities. Furthermore, conventional equity market responds negatively to terrorist attacks in Karachi and positively to attacks in financial cities and FATA. Interestingly, Islamic equity market responds positively towards the attacks in financial cities and FATA, however, with very minute reaction magnitude. The findings of this study are useful for the investors to manage their portfolios by considering magnitude and direction of market reaction towards terrorism based on the target type, location and Islamic months. Overall, this study concludes that conventional and Islamic equity markets reaction towards terrorism is very minute; however, the conventional and Islamic equity markets reaction varies based on target type, event location and different Islamic calendar months. Furthermore, the findings also suggest that equity markets recover very soon, therefore, markets are efficient in observing these shocks.
本文采用OLS回归和GARCH(1,1)模型,研究了2009年至2016年巴基斯坦传统和伊斯兰股票市场对恐怖主义事件的反应。前景理论和有效市场假说是相关理论。研究结果表明,传统和伊斯兰股票市场对恐怖主义事件的反应非常短暂,市场迅速恢复。本研究还根据目标类型、地点和伊斯兰历月份记录了市场对恐怖主义事件的反应。不同的目标类型和不同的事件地点对传统和伊斯兰股票市场的影响各不相同。巴基斯坦股票市场对袭击教育机构和企业的反应是消极的,而对袭击武装部队设施的反应是积极的。此外,传统股票市场对卡拉奇的恐怖袭击反应消极,对金融城市和联邦直辖部落地区的袭击反应积极。有趣的是,伊斯兰股票市场对金融城市和联邦直辖部落地区的袭击反应积极,但反应幅度非常小。本研究的结果有助于投资者根据目标类型、地点和伊斯兰月来考虑市场对恐怖主义的反应程度和方向,从而管理其投资组合。总体而言,本研究得出的结论是,传统和伊斯兰股市对恐怖主义的反应非常微小;然而,传统和伊斯兰股票市场的反应因目标类型、事件地点和不同的伊斯兰日历月份而异。此外,研究结果还表明,股票市场很快就会复苏,因此,市场在观察这些冲击方面是有效的。

Abstract This paper is aimed to examine the effect of Foreign Direct Investment inflow on Trade (Export, Import) in Turkey. The study copes the time span from 2006 Q2 to 2019 Q4. The time series datasets, those are retrieved from CBT and FRED database are used in applied econometrical methods such as ADF, PP, Zivot Andrews Unit Root Tests, ARDL bounds testing approach, and the Granger Causality tests, to accomplish the statistical part of the research. Based on the findings, it was supported that there was a positive relationship between FDI and Trade. Additionally, the outputs of Granger causality test indicated that there is a unidirectional causality running from FDI to Trade (Export and Import).

Abstract In general Women belonging to villages tend to spend the maximum of their time in household activities without any hesitation. In return, they don’t receive any merits or credits from the family and society. This paper aims in conducting detailed research work based on, the understanding found among women folk belonging to lower-middle-class women and poor income about the need for financial inclusion. The study was carried out in Ludhiana, Punjab among women from low-income and lower-middle-class households. Out of 1000 approaches, 757 respondents replied (75%). Later the data were organized and analyzed for the results. To make the work stronger a conceptual framework was framed. The tests like one-way ANOVA and Post-Hoc tests were also carried out. The outcomes showed that there are major differences seen when women are empowered and occupied they are reflecting positively on financial inclusion.
摘要农村妇女通常会毫不犹豫地把大部分时间花在家务活动上。作为回报,他们没有从家庭和社会获得任何功绩或荣誉。本文旨在开展详细的研究工作,基于对属于中下层妇女和低收入妇女的妇女群体对普惠金融需求的理解。这项研究是在旁遮普的卢迪亚纳进行的,调查对象是来自低收入和中下层家庭的妇女。在1000次提问中,有757次(75%)回答了问题。然后对数据进行整理和分析,得出结果。为了使这项工作更加有力,我们制定了一个概念框架。还进行了单因素方差分析和事后检验。结果表明,当妇女被赋予权力和被占领时,她们对金融包容性有积极的影响。

Abstract The concept of convexity plays an important role in the study of economics and consumer theory. For the most part, such studies have been conducted on the assumption that consumer preferences are a binary relation that is complete, reflexive and transitive on the set X of consumption choices. However, each consumer is a biological being with multidimensional physiological needs so that possible consumptions from different dimensions cannot be compared by using preferences. By removing that unrealistic assumption, this paper examines how the various concepts of convex preferences and relevant properties can be re-established. We derive a series of 10 formal propositions and construct 6 examples to show that (a) a weighted combination of two possible consumptions is not necessarily comparable with any of the consumptions; (b) not every convergent sequence of a consumer’s preferred consumptions asymptotically preserves that consumer’s preference preordering; (c) not all preferences satisfy either positive multiplicativity or additive conservation; (d) three types of preference convexities – weak convexity, convexity and strong convexity – can all be introduced into general convex spaces. This paper concludes with some research topics of expected significance for future works.
摘要凸性概念在经济学和消费者理论研究中占有重要地位。在大多数情况下,这些研究都是在假设消费者偏好是一种二元关系的基础上进行的,这种二元关系在消费选择集合X上是完全的、自反的和可传递的。然而,每个消费者都是一个具有多维生理需求的生物,因此无法通过偏好来比较来自不同维度的可能消费。通过消除这个不切实际的假设,本文探讨了如何重新建立凸偏好和相关属性的各种概念。我们推导了一系列10个形式命题,并构造了6个例子来表明:(a)两个可能消费的加权组合不一定与任何消费相比较;(b)并非消费者偏好消费的每一个收敛序列都渐近地保持消费者偏好的预先排序;(c)并非所有偏好都满足正乘法性或可加性守恒性;(d)三种类型的偏好凸——弱凸、凸和强凸——都可以引入到一般凸空间中。文章最后提出了一些对今后工作具有预期意义的研究课题。

Abstract The digitalization of the economy and society in the context of Industry 4.0 affects the labor market. New jobs are being created with new personnel requirements. At the same time, digitalization processes affect countries and sectors of the economy in different ways. The number of employed is declining in some sectors and increasing in others. The ratio of people employed in different industries also differs from country to country. As the digitalization of production relations intensifies, transformation processes in the labor market will increase. In the context of the actualization of digital changes in modern society, the aim of the article is to analyze the labor market under the digitalization of economic relations. The World Development Indicators (WDI) and Digital Intelligence Index (DII) were used to realize the purpose of the study. The study covers 89 countries for 2019. Correlation analysis, standardization, cluster analysis and analysis of variance were used as methods in the research. As a result of the study, the following conclusions were obtained. A strong relationship was found between Gross Domestic Product (GDP) and DII for the whole sample. The cluster analysis process found that the variables form three clusters with values of most indicators by group: at the high, the average and the low levels. Plots of mean and confidence intervals for the variables in each cluster were also plotted. Correlation coefficients were calculated for each cluster. It was found that each group has its own internal patterns.
工业4.0背景下经济和社会的数字化影响着劳动力市场。新的工作岗位不断涌现,对人员也有新的要求。与此同时,数字化进程以不同的方式影响着国家和经济部门。一些部门的就业人数在下降,而另一些部门的就业人数在增加。不同行业的就业人口比例也因国而异。随着生产关系数字化的加强,劳动力市场的转型过程将会增加。在现代社会实现数字化变革的背景下,本文旨在分析数字化经济关系下的劳动力市场。采用世界发展指标(WDI)和数字智能指数(DII)来实现研究目的。该研究涵盖了2019年的89个国家。研究采用了相关分析、标准化分析、聚类分析和方差分析等方法。通过研究,得出以下结论。在整个样本中,国内生产总值(GDP)和DII之间存在很强的关系。聚类分析过程发现,变量组成了三个聚类,大多数指标的值按组划分:高、平均和低水平。还绘制了每个簇中变量的均值和置信区间图。计算每个聚类的相关系数。研究发现,每个群体都有自己的内部模式。

Abstract This study empirically examined the role of the country’s absorptive capacity on the impact of domestic investment on economic growth in the selected five African countries over the study period of 1970 to 2019. In specific, the study examined the impact of domestic investment on economic growth from two models, without the country’s absorptive capacity and with the country’s absorptive capacity. Further, a robust linear ordinary least squares (OLS) methodology including static panel OLS and panel cointegration estimators was employed. The study found that only changes in financial development and infrastructures positively cause changes in the domestic investment-economic growth nexus in the short run while in the long run, trade openness enhances the positive impact of domestic investment on economic growth in African countries. In addition, the study found that domestic investment retards economic growth without the country’s absorptive capacity in the short run and long run respectively in African countries. Therefore, the study recommended that policymakers should invest heavily in infrastructure and financial development systems as well as encourages trade openness for a stable domestic investment-economic growth nexus in African countries.
本研究选取1970年至2019年五个非洲国家为研究对象,实证考察了国家吸收能力对国内投资对经济增长影响的作用。具体而言,该研究从两种模型考察了国内投资对经济增长的影响,一种是没有国家吸收能力,另一种是有国家吸收能力。此外,采用了一种稳健的线性普通最小二乘(OLS)方法,包括静态面板OLS和面板协整估计。研究发现,只有金融发展和基础设施的变化才会在短期内导致国内投资-经济增长关系的变化,而从长期来看,贸易开放增强了国内投资对经济增长的积极影响。此外,研究发现,在非洲国家,国内投资分别在短期和长期内阻碍了国家吸收能力的经济增长。因此,该研究建议政策制定者应大力投资于基础设施和金融发展体系,并鼓励贸易开放,以实现非洲国家稳定的国内投资-经济增长关系。

Abstract Biotic and abiotic carbon sequestration currently seems to be the only viable tools at the disposal of mankind for mitigating greenhouse gas (GHG) emissions and thus a remedy for tackling global warming challenges. This study accesses the global carbon capture and storage (CCS) programme: the level of success in its implementation and its impact using panel data from eight countries, the majority of which have begun one or more operational CCS facilities. To achieve this objective, fifteen years period time series data was sourced for the eight selected countries based on data availability, namely the United States (US), the United Kingdom (UK), Canada, China, Australia, Norway, South Africa, and Nigeria; ranging from 1990 to 2015. The panel ARDL results show that the explanatory variables, global industrial production (LIP), Electricity production (LEP), Agricultural production (LAP), transportation (LTR), and energy supply (LES) have a long-run relationship with the dependent variable (LGHG emissions). While the short-run results show that none of the variables have a significant contribution to LGHG emissions. In the long-run results, LIP and LTR significantly contribute to the reduction of LGHG courtesy of the CCS programme while LEP, LAP, and LES contribute to a rise in the LGHG emission. The cross-sectional results show that all the variables have significant impacts on LGHG in all the sampled countries except Australia. Suggesting that, the CCS programme is viable for mitigating global warming and climate change and therefore should be considered by the various countries of the world.
生物和非生物碳封存目前似乎是人类减少温室气体(GHG)排放的唯一可行工具,因此是应对全球变暖挑战的补救措施。本研究利用来自八个国家的面板数据访问了全球碳捕集与封存(CCS)计划:其实施的成功程度及其影响,其中大多数国家已经开始运营一个或多个CCS设施。为了实现这一目标,根据数据的可用性,为八个选定的国家提供了15年期间的时间序列数据,即美国、英国、加拿大、中国、澳大利亚、挪威、南非和尼日利亚;从1990年到2015年。面板ARDL结果表明,解释变量全球工业生产(LIP)、电力生产(LEP)、农业生产(LAP)、交通运输(LTR)和能源供应(LES)与因变量(LGHG排放)之间存在长期关系。而短期结果表明,没有一个变量对LGHG排放有显著贡献。在长期结果中,由于CCS计划,LIP和LTR显著有助于减少LGHG,而LEP、LAP和LES则有助于增加LGHG排放。横截面结果表明,除澳大利亚外,所有变量对LGHG均有显著影响。这表明CCS计划对于减缓全球变暖和气候变化是可行的,因此应该被世界各国考虑。

This paper gives an overview of foreign direct investment (FDI) in South Africa from 1980 to 2017. It highlights trends in FDI inflows, reforms that have been implemented to date, and challenges that need to be addressed in order to increase the FDI inflows into the country. Government reforms on FDI have been two pronged. Firstly, there are policies that are aimed at creating a strong competitive industry and a strong industrial base for investment. Among such policies are trade liberalisation policies, multilateral and regional integration policies, supportive industrial policies, and bilateral trade agreements. Secondly, there are policies that directly target the FDI investment. These policies include, amongst others, investment incentives, regulatory reforms, exchange control relaxation, and Bilateral Investment Treaties (BITs) reforms. The findings from this study show that FDI inflows have increased significantly from 1990 although they still remain depressed.
本文对1980年至2017年南非的外国直接投资(FDI)进行了概述。报告强调了外国直接投资流入的趋势、迄今为止实施的改革以及为增加流入该国的外国直接投资需要解决的挑战。政府对外国直接投资的改革是双管齐下的。首先,有一些政策旨在创造一个强大的有竞争力的工业和一个强大的工业投资基础。这些政策包括贸易自由化政策、多边和区域一体化政策、支持性产业政策和双边贸易协定。其次,有直接针对外国直接投资的政策。这些政策包括投资激励、监管改革、放松外汇管制和双边投资条约(BITs)改革等。这项研究的结果表明,外国直接投资流入自1990年以来显著增加,尽管它们仍然很低。

The current study uses an adapted version of Cameron and Quinn’s OCAI questionnaire to test the organisational culture of the Faculty of Science and Technology at the University of Debrecen, Hungary, as it is perceived by its students, and also to discover what type of organisational culture the same students think would be ideal for them. An additional objective of this paper is to identify possible gaps between the perceived and the ideal cultures expressed by the students. Our sample includes 128 questionnaires completed by bachelor students from 6 different majors at the faculty. According to our results, the respondents perceive to a significant degree that the faculty’s organisational culture is at an average level of clan, market and hierarchy cultures, while it also exhibits a relatively low level of the adhocracy culture. Their ideal faculty culture would be one with average adhocracy, average hierarchy, high clan and low market features. Significant gaps are identified between the perceived and ideal cultures in all the four types: students would prefer an increase in clan and adhocracy cultures, and a decrease in the other two cultures.
目前的研究使用了Cameron和Quinn的OCAI问卷的一个改编版本来测试匈牙利德布雷森大学科技学院的组织文化,因为它是由学生感知的,也发现了同样的学生认为哪种类型的组织文化对他们来说是理想的。本文的另一个目的是确定学生所表达的感知文化和理想文化之间可能存在的差距。我们的样本包括来自学院6个不同专业的本科生完成的128份问卷。根据我们的研究结果,受访者在很大程度上认为该学院的组织文化处于氏族文化、市场文化和等级文化的平均水平,而它也表现出相对较低的民主文化水平。他们理想的教师文化应该是一种平均民主、平均等级、高宗族、低市场特征的教师文化。在所有四种类型的感知文化和理想文化之间发现了显著的差距:学生更喜欢氏族文化和民主文化的增加,而其他两种文化的减少。
