This paper aims to investigate the effects of personal characteristics such as gender, income, education and age on consumer materialism. Research hypotheses are based on both existing marketing literature and an additional integration of gender studies literature in order to further the study of materialism. By using random sampling and surveying 1000 respondents living across different regions in Lithuania, the results show significant differences along gender, age, self-perceived relative income and education in terms of consumers’ materialistic dispositions. The study confirms that younger consumers are more inclined to materialistic values than older ones. Women differ from men on materialism centrality, as well as happiness and success measures. Regarding consumers’ self-perceived relative income, Lithuanians with low income are more prone to aspire to material possessions. Furthermore, research indicates higher rates of consumer materialism to appear among less educated individuals. This is one of the first representative studies in Lithuania revealing what effects different demographic consumer characteristics have on materialistic behaviour. Our findings have some practical implications; for example, they show that vulnerable segments of the population are more susceptible to materialism, necessitating educational policies to reduce such behavior and encourage a more responsible approach. As a result, these educational programs should be tailored to these individuals, with a greater emphasis on the risks associated with overconsumption.
本文旨在探讨性别、收入、教育程度、年龄等个人特征对消费物质主义的影响。为了进一步研究唯物主义,研究假设是基于现有的营销文献和对性别研究文献的额外整合。通过随机抽样和调查生活在立陶宛不同地区的1000名受访者,结果显示,在消费者的物质倾向方面,性别、年龄、自我感知的相对收入和教育程度存在显著差异。研究证实,年轻的消费者比年长的消费者更倾向于物质主义价值观。女性与男性在物质至上、幸福和成功的衡量标准上存在差异。在消费者自我感知的相对收入方面,低收入的立陶宛人更倾向于追求物质财富。此外,研究表明,在受教育程度较低的人群中,消费物质主义的比例更高。这是立陶宛第一批具有代表性的研究之一,揭示了不同人口统计消费者特征对物质主义行为的影响。我们的发现有一些实际意义;例如,它们表明人口中的脆弱部分更容易受到物质主义的影响,因此有必要制定教育政策来减少这种行为并鼓励采取更负责任的做法。因此,这些教育计划应该针对这些人量身定制,更加强调与过度消费相关的风险。

In order to forecast stock prices based on economic indicators, many studies have been conducted using well-known statistical methods. Meanwhile, since ~2010 as the power of computers improved, new methods of machine learning began to be used. It would be interesting to know how those algorithms using a variety of mathematical and statistical methods, are able to predict the stock market. The purpose of this article is to model the monthly price of the S&P 500 index based on U.S. economic indicators using statistical, machine learning, deep learning approaches and finally compare metrics of those models. After the selection of indicators according to the data visualization, multicollinearity tests, statistical significance tests, 3 out of 27 indicators remained. The main finding of the research is that the authors improved the baseline statistical linear regression model by 19 percent using a ML Random Forest algorithm. In this way, model achieved accuracy 97.68% of prediction S&P 500 index.

Covid-19 brought the new reality into every-day life, global economy, and various sectors, including independent convenience stores. After the first and during the second wave of Coronavirus in the United Kingdom (mid-November 2020), the overall situation was very dynamic and turbulent. This paper is thus aimed at answering the question how the independent convenience stores sector in the United Kingdom functions in the Covid-19 reality. We analyse such issues as the recession phase in the global economy, and challenges the independent convenience stores sector in the UK faces, including the changing aspects of the consumer shopping behaviour. We identify the changes in the footfall, basket spend, sale, product categories, etc. Finally, we conclude that the convenience store sector in the UK is relatively resistant to Covid-19 pandemic and emphasise the most challenging consumer behaviour aspects in the middle of the Covid-19 pandemic.
新冠疫情给日常生活、世界经济、独立便利店等各个领域带来了新的现实。在英国第一波和第二波冠状病毒疫情之后(2020年11月中旬),整体形势非常动态和动荡。因此,本文旨在回答英国独立便利店行业在Covid-19现实中如何运作的问题。我们分析了诸如全球经济衰退阶段等问题,以及英国独立便利店部门面临的挑战,包括消费者购物行为的变化方面。我们确定客流量、购物篮支出、销售额、产品类别等方面的变化。最后,我们得出结论,英国的便利店行业对Covid-19大流行的抵抗力相对较强,并强调了在Covid-19大流行期间最具挑战性的消费者行为方面。

The paper examines the determinants of voluntary International Financial Reporting Standards (IFRS) adoption in Poland. In doing so, it empirically confirms the impact of diverse CEO and supervisory board characteristics on voluntary IFRS adoption. The paper focuses on  446 publicly traded production companies from Poland. The analysis is based on logistic regression analysis. The empirical investigation  confirms the impact on voluntary IFRS adoption of such factors as company size, international investors, international supervisory board, number of supervisory board members, CEO nationality. The paper  contributes to the assessment of  voluntary IFRS adoption determinants, by presenting for the first time CEO and supervisory board characteristics and their impact on voluntary International Financial Reporting Standards (IFRS) adoption, and the determinants of IFRS adoption from Central and Eastern Europe. The paper enhances  existing knowledge of voluntary IFRS adoption by incorporating  new CEO and supervisory board characteristics, thus closing a gap in the relevant literature. The results of the paper are significant from the supervisor’s perspective, the quality of financial statements and the effectiveness of corporate governance systems.
本文考察了自愿采用国际财务报告准则(IFRS)在波兰的决定因素。在此过程中,实证证实了CEO和监事会的不同特征对自愿采用国际财务报告准则的影响。本文关注的是波兰446家上市制作公司。分析基于逻辑回归分析。实证调查证实了公司规模、国际投资者、国际监事会、监事会成员人数、CEO国籍等因素对自愿采用国际财务报告准则的影响。本文通过首次介绍CEO和监事会特征及其对自愿采用国际财务报告准则(IFRS)的影响,以及中欧和东欧采用国际财务报告准则的决定因素,有助于评估自愿采用国际财务报告准则的决定因素。本文通过纳入新的CEO和监事会特征,增强了对自愿采用国际财务报告准则的现有知识,从而缩小了相关文献中的空白。本文的研究结果从监事角度、财务报表质量和公司治理制度的有效性三个方面都具有重要意义。

The objective of this paper is to investigate and forecast the determinants of Montenegrin inflation empirically, using forecast combination methods, from January 2006 to December 2016, and out-of-sample 12-month horizon forecasting from January 2017 to December 2017. The main research problem is that given the struggle policymakers have had to define proper criteria to diagnose the onset of inflation indicators, we felt compelled to identify an approach and methodology that the government of Montenegro can use in the threshold to accessing the European Union. We examine three individual-predictor SVAR models to forecast inflation.  Model 1 examines the internal determinants of inflation. Model 2 relates to demand-pull and cost-push variables. Model 3 examines external determinants. Combining the above three forecasts, we disclose two more RMSEs: equal and inverse MSE weights. Model 1 predicts inflation at 1.3%, the inverse MSE at 1.5%, and the weighted average at 1.4%. They show forecasting performances that are sustainable and average inflation not more than 1.5% above the rate of the three best performing Member states: Cyprus (0.2%), Ireland (0.3%), and Finland (0.8%) over the 12 months covering April 2017-March 2018. Our findings allow the policymakers to understand the factors involved in identifying the onset of inflation dynamics and inflation expectations in Montenegro better and develop more effective government regulations that can be employed nationally. In so doing, this research advances and recommends the toolset needed, combining forecasts, to combat the concerns of many macroprudential policymakers in Montenegro, especially the Central Bank of Montenegro.
本文的目的是利用预测组合方法,从2006年1月至2016年12月,以及2017年1月至2017年12月的样本外12个月水平预测,对黑山通货膨胀的决定因素进行实证研究和预测。主要的研究问题是,考虑到政策制定者不得不定义适当的标准来诊断通货膨胀指标的开始,我们感到有必要确定黑山政府可以在进入欧盟门槛时使用的方法和方法。我们检验了三个个体预测变量SVAR模型来预测通货膨胀。模型1考察了通货膨胀的内部决定因素。模型2涉及需求拉动和成本推动变量。模型3检验外部决定因素。结合上述三种预测,我们揭示了另外两种均方根误差:相等和相反的均方根误差权重。模型1预测通货膨胀率为1.3%,逆MSE为1.5%,加权平均值为1.4%。在2017年4月至2018年3月的12个月里,它们的预测表现是可持续的,平均通货膨胀率不超过三个表现最好的成员国的1.5%:塞浦路斯(0.2%)、爱尔兰(0.3%)和芬兰(0.8%)。我们的研究结果使政策制定者能够更好地了解确定黑山通胀动态和通胀预期开始的因素,并制定可在全国范围内采用的更有效的政府法规。在此过程中,本研究推进并建议了所需的工具集,结合预测,以解决黑山许多宏观审慎政策制定者,特别是黑山中央银行的担忧。

Regarding existing pressures for effectiveness and performance improvement, there is a steep rise for the establishment of Enterprise Resource Planning (ERP). Unfortunately, failure rate for successful ERP establishment is high. Thereupon, evaluation of organizations’ preparedness to ensure organizational capabilities aimed at reaching desired outcomes is of paramount importance. The current research is intended to suggest Step-wise Weight Assessment Ractio Analysis (SWARA) method and assess the preparedness of our case study, i.e. the University of Mazandaran, for successful ERP implementation. Related factors impacting on the accomplishment of the ERP system were identified from former studies and weighted according to a hierarchical structure using our suggested methodology. After receiving numerical results, the preparedness of the University of Mazandaran for successful ERP implementation was calculated when the final weights were determined. Results showed that motivations required for ERP establishment as well as processes and IT infrastructures are average, while the influencing cultural factors, protective factors, and capabilities of the organization are weak.
对于现有的有效性和绩效改进的压力,企业资源规划(ERP)的建立急剧上升。不幸的是,成功建立ERP的失败率很高。因此,评估组织的准备,以确保组织的能力,以达到预期的结果是至关重要的。目前的研究旨在建议逐步权重评估比例分析(SWARA)方法,并评估我们的案例研究(即马赞达兰大学)为成功实施ERP所做的准备。从以往的研究中确定影响ERP系统完成的相关因素,并使用我们建议的方法根据层次结构进行加权。在得到数值结果后,当最终权重确定时,计算马赞达兰大学成功实施ERP的准备情况。结果表明,企业建立ERP所需的动机、流程和IT基础设施的动机处于中等水平,而企业文化因素、保护因素和能力的影响较弱。

The stability of the economic system of a country very much depends on its banking industry. Data Envelopment Analysis (DEA) has been applied widely for measuring efficiency of banks. Limited studies, however, have employed the radial and non-radial DEA models to evaluate efficiency of banks without considering the ranking of the fully efficient banks since those banks have the same efficiency score. Considering the weakness of the radial and non-radial DEA, this paper aims to calculate the banks efficiency of nine commercial banks in Malaysia from 2004 to 2013 by adopting the two-stage of super efficiency slack-based measure (SE-SBM) model. This model can discriminate between the efficient banks and recalculate their efficiency scores. Then, the selected banks were able to be ranked according to their final efficiency scores. Moreover, comparative analyses of the efficiency of the banks and the year-wise efficiency of the selected banks were also conducted. The methodology consists of two stages.  In the first stage the SBM model is run to classify efficient and inefficient banks. In the second stage the super efficiency model is run to rank the efficient banks obtained from the first stage by calculating their super efficiency scores. Our empirical results show that: (1) the efficiency status of the banks fluctuated over the examined period, the high number of the efficient banks is achieved in the years 2006 and 2008, while the year 2012 has the lowest number of the efficient banks. (2) the ranking of the banks fluctuated in the studied period. (3) most of the banks are inefficient in terms of their average efficiency scores. This paper has two limitations. First, the paper did not integrate undesirable output, despite it deals with non-interest income. Second, performance evaluation of Malaysian commercial banks was only compared among the Malaysian banks.
一个国家经济体系的稳定在很大程度上取决于它的银行业。数据包络分析(DEA)在衡量银行效率方面得到了广泛的应用。然而,由于完全有效银行的效率得分相同,因此很少有研究采用径向和非径向DEA模型来评价银行的效率,而没有考虑完全有效银行的排名。考虑到径向DEA和非径向DEA的不足,本文采用两阶段超效率松弛测度(SE-SBM)模型对马来西亚9家商业银行2004 - 2013年的银行效率进行了计算。该模型可以区分效率高的银行,并重新计算其效率分数。然后,被选中的银行能够根据它们的最终效率得分进行排名。此外,还对所选银行的效率和年度效率进行了比较分析。该方法包括两个阶段。第一阶段运用SBM模型对高效银行和低效银行进行分类。第二阶段运用超效率模型对第一阶段得到的高效银行进行排名,计算其超效率得分。实证结果表明:(1)银行效率状况在研究期间存在波动,2006年和2008年效率银行数量最多,2012年效率银行数量最少。(2)银行排名在研究期内波动较大。(3)从平均效率得分来看,大多数银行效率低下。本文有两个局限性。首先,尽管本文涉及的是非利息收入,但并未纳入不良产出。第二,对马来西亚商业银行的绩效评价仅在马来西亚银行之间进行比较。
