Abstract This paper investigates the relationship between the implementation of the Family 500+ benefit, changes in female employment and female economic inactivity. The analysis is based on macro data and is focused on the years 2016–2019. To examine the relationship, this study uses decomposition of the employment-to-population ratio change into labour supply and unemployment components, analysis of changes in the structure of nonparticipants and the shift-share method. Considering that the reaction to the child benefit may differ across age groups, this study found that since the introduction of the Family 500+ benefit, the employment-to-population ratio for women aged 25–39 (the most likely age group to be raising children and therefore to receive the benefit) stagnated, their labour force participation rate decreased and the percentage of nonparticipants due to family and household responsibilities increased.
摘要本文研究了“500+家庭”福利的实施与女性就业变化和女性经济不活动之间的关系。该分析基于宏观数据,重点关注2016-2019年。为了检验这种关系,本研究将就业人口比变化分解为劳动力供给和失业组成部分,分析非参与者结构的变化,并采用转移份额法。考虑到不同年龄组对儿童福利的反应可能不同,本研究发现,自从引入家庭500+福利以来,25-39岁女性(最有可能抚养孩子并因此获得福利的年龄组)的就业与人口比率停滞不前,她们的劳动力参与率下降,由于家庭和家庭责任而不参与的比例增加。

Abstract The war in Ukraine affects the European Union (EU) member states asymmetrically. The purpose of the study is to determine changes in the development of the EU countries in three key directions: ‘economy and environment’, ‘business and trade’, and ‘people and work’; to identify clusters of countries with similar transformations; and to model the impact of the studied indicators on the level of public debt amid the war in Ukraine. The research methodology includes the definition of a complex indicator of changes in the socio-economic development of EU countries, correlation and cluster analysis, and modelling the influence of the studied factors/indicators on the level of public debt. Research of changes in the context of the proposed complex indicators and their components under conditions of war showed that the changes in the areas under review varied for EU countries. Against the backdrop of the war in Ukraine, 17 EU countries faced a slowdown in their socio-economic growth, among which Poland was the most severely affected. Modelling made it possible to determine that, amid the war, the most important factors for the EU public debt are inflation, labour market conditions, and the possibilities of the balance of payments and the international investment position incorporated into GDP. The conducted research proves that the war in Ukraine increases the scale and relevance of general challenges that cannot be addressed at the national level. Strengthening the European defence against external aggression is the entire task of the EU.
乌克兰战争对欧盟成员国的影响是不对称的。该研究的目的是确定欧盟国家在三个关键方向上的发展变化:“经济与环境”、“商业与贸易”和“人员与工作”;确定具有类似转变的国家群;并模拟研究指标对乌克兰战争期间公共债务水平的影响。研究方法包括定义欧盟国家社会经济发展变化的复杂指标、相关性和聚类分析,以及对所研究的因素/指标对公共债务水平的影响进行建模。对拟议的复杂指标及其组成部分在战争条件下的变化进行的研究表明,欧盟各国在审查的领域的变化各不相同。在乌克兰战争的背景下,17个欧盟国家的社会经济增长放缓,其中波兰受到的影响最为严重。通过建模可以确定,在战争期间,影响欧盟公共债务的最重要因素是通货膨胀、劳动力市场状况、国际收支以及将国际投资状况纳入GDP的可能性。所进行的研究证明,乌克兰战争增加了无法在国家一级解决的一般挑战的规模和相关性。加强欧洲防御外来侵略是欧盟的全部任务。

Abstract Despite recent studies focused on comparing the dynamics of market efficiency between Bitcoin and other traditional assets, there is a lack of knowledge about whether Bitcoin and emerging markets efficiency behave similarly. This paper aims to compare the market efficiency dynamics between Bitcoin and the emerging stock markets. In particular, this study indicates whether the dynamics of Bitcoin market efficiency mimic those of emerging stock markets. Thus, the paper's contribution emerges from the combination of Bitcoin and emerging markets in the field of dynamics of market efficiency. The dynamics of market efficiency are measured using the Hurst exponent in the rolling window. The study uses daily data for the MSCI Emerging Markets Index and the Bitcoin market over the period 2011–2022. Our results show that there is at most a moderate correlation between the dynamics of Bitcoin and emerging stock markets’ efficiency over the entire study period. The strongest correlations occur mainly in periods of high economic policy uncertainty in the largest Bitcoin mining countries. Therefore, the association between Bitcoin market efficiency and emerging stock markets’ efficiency may strengthen with an increase in economic policy uncertainty. These findings may be useful for investors and portfolio managers in constructing better investment strategies.
尽管最近的研究集中在比较比特币和其他传统资产之间的市场效率动态,但缺乏关于比特币和新兴市场效率是否相似的知识。本文旨在比较比特币和新兴股票市场之间的市场效率动态。特别是,这项研究表明,比特币市场效率的动态是否模仿新兴股票市场的动态。因此,本文的贡献来自于比特币与新兴市场在市场效率动力学领域的结合。利用赫斯特指数在滚动窗口中测量市场效率的动态。该研究使用了2011年至2022年期间MSCI新兴市场指数和比特币市场的每日数据。我们的研究结果表明,在整个研究期间,比特币的动态与新兴股票市场的效率之间最多存在适度的相关性。最强的相关性主要发生在最大的比特币开采国经济政策高度不确定的时期。因此,随着经济政策不确定性的增加,比特币市场效率与新兴股票市场效率之间的关联可能会加强。这些发现可能对投资者和投资组合经理构建更好的投资策略有用。

Abstract This study contrasts GARCH models with diverse combined forecast techniques for Commodities Value at Risk (VaR) modeling, aiming to enhance accuracy and provide novel insights. Employing daily returns data from 2000 to 2020 for gold, silver, oil, gas, and copper, various combination methods are evaluated using the Model Confidence Set (MCS) procedure. Results show individual models excel in forecasting VaR at a 0.975 confidence level, while combined methods outperform at 0.99 confidence. Especially during high uncertainty, as during COVID-19, combined forecasts prove more effective. Surprisingly, simple methods such as mean or lowest VaR yield optimal results, highlighting their efficacy. This study contributes by offering a broad comparison of forecasting methods, covering a substantial period, and dissecting crisis and prosperity phases. This advances understanding in financial forecasting, benefiting both academia and practitioners.
本研究将GARCH模型与多种组合预测技术用于商品风险价值(VaR)建模进行对比,旨在提高准确性并提供新的见解。采用2000年至2020年黄金、白银、石油、天然气和铜的每日收益数据,使用模型置信集(MCS)程序对各种组合方法进行了评估。结果表明,单个模型在0.975置信水平下的VaR预测效果较好,而组合方法在0.99置信水平下的VaR预测效果较好。特别是在高度不确定性期间,如2019冠状病毒病期间,综合预测被证明更有效。令人惊讶的是,简单的方法,如平均或最低的VaR产生最佳的结果,突出其功效。这项研究的贡献在于提供了广泛的预测方法比较,涵盖了相当长的时期,并剖析了危机和繁荣阶段。这促进了对财务预测的理解,使学术界和实践者都受益。

Abstract Financial markets are seen as one of the most important markets in economic terms. The activities of investors in the financial markets consist in predicting how best to invest the accumulated capital, using all kinds of analyzes and forecasts. In the literature on the subject, apart from fundamental analysis, technical analysis is distinguished. While the first one is to help you choose a specific asset with profitable potential, technical analysis is designed to help the investor find a specific moment that is most suitable for buying or selling. The aim of the article is to demonstrate the potential benefits associated with modifying the default settings of technical analysis indicators on the example of the EUR/USD currency pair using the MetaTrader4 investment platform. Analizing was carried out on the basis of the most popular currency pair in terms of turnover on the Forex market - EUR/USD. The research used an investment strategy based on Parabolic SAR and Relative Strength Index RSI technical analysis indicators, whose indications were verified both in the context of default settings and after the author‘s modification. The results of the conducted research indicate significant differences, depending on the adopted parameters of the above-mentioned indicators.
金融市场被视为最重要的经济市场之一。投资者在金融市场上的活动是利用各种分析和预测,预测如何最好地投资积累的资本。在有关该主题的文献中,除了基本面分析外,还区分了技术分析。第一个是帮助你选择有盈利潜力的特定资产,而技术分析的目的是帮助投资者找到最适合买入或卖出的特定时刻。本文的目的是展示使用MetaTrader4投资平台修改欧元/美元货币对的技术分析指标默认设置的潜在好处。分析是基于外汇市场上最受欢迎的货币对——欧元/美元的成交量。本研究采用了基于抛物线SAR和相对强弱指数RSI技术分析指标的投资策略,并在默认设置和笔者修改后对其指标进行了验证。根据上述指标所采用的参数不同,所进行的研究结果存在显著差异。

Abstract The Russian invasion of Ukraine in late February of 2022 caused a humanitarian refugee crisis on a scale unseen since World War II. The scale and speed at which refugees surged into other European countries required significant resources to respond to this influx. This study explores the perspectives of those working in NGOs about the resilience of their organisations in responding to the Ukrainian refugee crisis in the Czech Republic. Drawing on interview data collected at the beginning of the refugee response in the Czech Republic between February and June of 2022, our findings suggest that NGOs face capacity and governance challenges, and these system-level barriers inhibit NGO resilience and their ability to respond effectively to the Ukrainian refugee crisis in the long term. These lasting effects influence NGO resilience in the face of the unprecedented Ukrainian crisis. Despite these barriers, NGOs acted with flexibility and agility in delivering humanitarian assistance to Ukrainian refugees in the first few months of the crisis. The findings from this study indicate NGOs engage in organisational resilience strategies within a policy and governance system that lacks the adaptability and coordination needed to be resilient.
2022年2月下旬,俄罗斯入侵乌克兰,引发了二战以来规模最大的人道主义难民危机。难民涌入其他欧洲国家的规模和速度需要大量资源来应对这种涌入。本研究探讨了那些在非政府组织工作的人对他们的组织在捷克共和国应对乌克兰难民危机的弹性的看法。根据2022年2月至6月捷克共和国难民响应开始时收集的访谈数据,我们的研究结果表明,非政府组织面临能力和治理挑战,这些系统层面的障碍抑制了非政府组织的复原力和长期有效应对乌克兰难民危机的能力。这些持久的影响影响了非政府组织在面对前所未有的乌克兰危机时的复原力。尽管存在这些障碍,在危机发生的头几个月里,非政府组织在向乌克兰难民提供人道主义援助方面表现出灵活性和敏捷性。本研究的结果表明,非政府组织在缺乏弹性所需的适应性和协调的政策和治理体系中参与组织弹性战略。

Towards a better understanding of self-selection to teacher training programmes: A case study of a renowned public university in Poland 更好地理解教师培训方案的自我选择:以波兰一所著名公立大学为例

Abstract It is difficult to achieve high-quality education without good teachers. Therefore, it is crucial to understand who decides to become a teacher. This study leverages a large-scale administrative dataset comprising detailed records of the educational trajectories of 10 cohorts of students at the University of Warsaw, the largest higher education institution in Poland, in order to investigate self-selection to the teaching profession and to learn whether it depends on the mode of teacher training and the student's primary field of studies. We find that the recruitment of students to the concurrent teacher training programme is characterised by adverse self-selection with respect to prior academic achievements. When it comes to consecutive programmes, pursued as an extension or specialisation within the major programme, the willingness of students to enroll in teacher training is related to their secondary school achievements, but also – and in a distinct way – to their early experience at the university. In the case of STEM and foreign language programmes, we observe adverse selection to teacher training with respect to either the student's pre-university academic outcomes or their achievements during the first year of university studies.
没有优秀的教师,就很难实现高质量的教育。因此,了解谁决定成为一名教师是至关重要的。本研究利用了一个大规模的管理数据集,其中包括波兰最大的高等教育机构华沙大学10组学生的教育轨迹的详细记录,以调查教师职业的自我选择,并了解它是否取决于教师培训模式和学生的主要研究领域。我们发现,学生的招聘并行教师培训计划的特点是不利的自我选择相对于先前的学术成就。当涉及到连续课程时,作为专业课程的延伸或专业,学生参加教师培训的意愿与他们的中学成绩有关,但也以一种独特的方式与他们在大学的早期经历有关。在STEM和外语课程的情况下,我们观察到教师培训在学生大学前的学术成果或他们在大学第一年的学习成绩方面的逆向选择。

Abstract The main objective of the presented research is to verify the influence of demographic factors on retail customers’ bank selection criteria in Poland. We compiled descriptive and inferential statistics and did factor analysis using Principal Component Analysis. Our dataset is based on a sample of 515 questionnaires that were gathered in the first quarter of 2022. The results proved that there are significant differences among various groups of respondents and their bank selection criteria. The highest number of differences appear in the case of demographic factors of age, and then income and gender. In general, the most important factors are the cost of service and mobile and online banking. The study has direct implications for all types of banks that operate in developing markets, especially in East-Central Europe, as having this knowledge can help to appropriately target customers using bank selection criteria that are valued by different groups of customers.
摘要本研究的主要目的是验证波兰人口因素对零售客户银行选择标准的影响。我们编制了描述性统计和推断性统计,并使用主成分分析进行了因子分析。我们的数据集基于2022年第一季度收集的515份问卷样本。结果证明,不同的受访者群体和他们的银行选择标准存在显著差异。最大的差异出现在年龄等人口因素,然后是收入和性别。总的来说,最重要的因素是服务成本以及手机和网上银行。这项研究对在发展中市场(特别是中东欧)经营的所有类型的银行都有直接的影响,因为了解这些知识可以帮助使用不同客户群体所重视的银行选择标准来适当地瞄准客户。

The study has direct implications for all types of banks that operate in developing markets, especially in East-Central Europe, as having this knowledge can help to appropriately target customers using bank selection criteria that are valued by different groups of customers.","PeriodicalId":9951,"journal":{"name":"Central European Journal of Economic Modelling and Econometrics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135839881","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}

Abstract The aim of this paper is to ascertain corporate investment reaction in bank-dependent companies in times of crisis. Our investigation covers the differences in corporate investment reaction due to the global financial crisis (GFC) of 2007–2009 and the COVID-19 crisis of 2020–2021. We utilized panel data of companies present on the Warsaw Stock Exchange during the GFC and COVID-19 crisis—932 firm-year observations. We found a negative relationship between bank dependence (static ratio) and corporate investment, but a statistical significance was found only for the GFC period. We also found a positive relationship between bank dependence (dynamic ratio) and corporate investment, but statistical significance was found only for the GFC period. Additionally, we found that during the COVID-19 crisis, the level of corporate investment was at its lowest level, but the biggest drop was noticeable during the GFC when compared to the pre-GFC period. Our article contributes to the existing research by being part of the research on corporate investment and capital structure. It consists of the research on one of the determinants of the corporate investment and capital structure decisions—macroeconomic turbulence manifested in economic crises.
摘要本文的目的是确定银行依赖企业在危机时期的企业投资反应。我们的调查涵盖了2007-2009年全球金融危机(GFC)和2020-2021年COVID-19危机期间企业投资反应的差异。我们使用了在全球金融危机和COVID-19危机期间在华沙证券交易所上市的公司的面板数据- 932公司年观察。我们发现银行依赖(静态比率)与企业投资之间存在负相关关系,但只有在全球金融危机期间才有统计学意义。我们还发现银行依赖性(动态比率)与企业投资之间存在正相关关系,但仅在全球金融危机期间才有统计学意义。此外,我们发现,在2019冠状病毒病危机期间,企业投资水平处于最低水平,但与全球金融危机前相比,全球金融危机期间的降幅最大。本文作为企业投资与资本结构研究的一部分,对已有的研究有所贡献。它包括对企业投资和资本结构决策的决定因素之一——经济危机中表现出来的宏观经济动荡的研究。

The Unpredicted Rise of Populism: The Case of Poland 民粹主义的意外崛起:以波兰为例

Abstract This article investigates the rise of populism in Poland, applying an interdisciplinary method, with political, social, and economic factors as the compound reason for the turn from liberalism towards populism. The methodology of the study is the exploratory analysis of research, historical materials on Poland's transition to capitalism, and calculation of the selected empirical data of household incomes, linked to election results, in the regional cross-section. The household economic condition was validated by a report on deprivation and the presented growth of households’ disposable income, exposing regional differences between the selected voivodeships. The populist party Law and Justice (PiS) won the two last elections, with the majority of votes in low-income regions, which proved the hypothesis that economic inequality, amplified by globalisation and transition disparities were the main reasons for populism's prevalence. The democratic backsliding has not changed party-political scenery for very long, which revealed that for the majority of Polish voters, economic upgrading counted more, despite the violation of democracy. Therefore, the advance of knowledge about measures to reduce the in-country socioeconomic disparities between regions has become more important.
摘要本文运用跨学科的研究方法,考察了波兰民粹主义的兴起,认为政治、社会和经济因素是波兰从自由主义转向民粹主义的复合原因。该研究的方法是对波兰向资本主义过渡的研究、历史材料进行探索性分析,并在区域横截面中计算与选举结果相关的选定的家庭收入经验数据。一份关于贫困和家庭可支配收入增长的报告证实了家庭经济状况,暴露了所选省份之间的区域差异。民粹主义政党法律与公正党(PiS)赢得了最近两次选举,在低收入地区获得了大多数选票,这证明了一个假设,即全球化和转型差距放大的经济不平等是民粹主义盛行的主要原因。民主倒退并没有改变党派政治格局很长一段时间,这表明对大多数波兰选民来说,经济升级更重要,尽管违反了民主。因此,关于减少地区间国内社会经济差距的措施的知识进步变得更加重要。
