Abstract Fraud presents a serious problem and arising issue for all of society at national and global levels. According to global fraud research conducted by the Association of Certified Fraud Examiners, it is estimated that the average company loses about 5% of its annual revenue due to different types of business fraud. Total estimated annual fraud losses according to global ACFE research reaches about 4.7 trillion dollars. Business frauds also present an important issue for the Croatian economy, business community and society as a whole. Thereby, considerable attention should be given to this issue with the aim of raising awareness throughout society on fraud and its negative and destructive impact on all of society. The main purpose of this paper is to examine differences in fraud characteristics between state-owned and private companies in the Republic of Croatia. Research was based on data on business frauds obtained by the Association of Certified Fraud Examiners Croatia which included 124 respondents. Data were related to frauds that occurred in Croatian companies in 2021 and 2020. In this paper we focused on fraud characteristics such as fraud loss, type of fraud, fraud duration and methods of fraud detection in order to determine whether fraud in privately owned companies differs significantly from fraud in state-owned companies. Research results revealed how differences in fraud characteristics among privately and state-owned companies exist. Based on a sample of Croatian companies that were victims of fraud, it is noted how fraud in state-owned companies lasts longer and creates greater loses in comparison to fraud in private owned companies. Moreover, data related to estimated fraud loss and fraud duration were statistically significant in terms of differentiating these two groups of companies. Based on data on discriminatory variables a logistic regression model correctly classified 78.46% of companies in the group of companies that are privately or state-owned.
摘要 欺诈是一个严重的问题,在国家和全球层面都引起了全社会的关注。根据美国注册舞弊审查师协会(Association of Certified Fraud Examiners)进行的全球舞弊研究,估计平均每家公司每年因不同类型的商业舞弊而损失的收入约占其年收入的 5%。根据 ACFE 的全球研究,估计每年的欺诈损失总额约为 4.7 万亿美元。商业欺诈也是克罗地亚经济、商界和整个社会面临的一个重要问题。因此,应高度重视这一问题,以提高全社会对欺诈及其对整个社会的负面和破坏性影响的认识。本文的主要目的是研究克罗地亚共和国国有企业和私营企业在欺诈特征方面的差异。研究以克罗地亚注册舞弊审查师协会获得的商业欺诈数据为基础,其中包括 124 名受访者。数据涉及 2021 年和 2020 年克罗地亚公司发生的欺诈事件。在本文中,我们重点关注欺诈特征,如欺诈损失、欺诈类型、欺诈持续时间和欺诈侦查方法,以确定私营公司中的欺诈与国有公司中的欺诈是否存在显著差异。研究结果揭示了私营企业与国有企业在欺诈特征方面存在的差异。根据受欺诈之害的克罗地亚公司样本,可以发现国有公司的欺诈行为与私营公司的欺诈行为相比,持续时间更长,造成的损失更大。此外,与估计欺诈损失和欺诈持续时间有关的数据在区分这两类公司方面具有统计学意义。根据判别变量的数据,逻辑回归模型正确地将 78.46%的公司划分为私营或国有公司。

Abstract This study aims to predict the ESG (environmental, social, and governance) return volatility based on ESG index data from 26 October 2017 and 31 March 2023 in the case of India. In this study, we utilized GARCH (Generalized Autoregressive Conditional Heteroskedasticity) and LSTM (Long Short-Term Memory) models for forecasting the return of ESG volatility and to evaluate the model’s suitability for prediction. The study’s findings demonstrate the GARCH effect inside the ESG return volatility data, indicating the occurrence of volatility in response to market fluctuations. This study provides insight concerning the suitability of models for volatility predictions. Moreover, based on the analysis of the return volatility of the ESG index, the GARCH model is more appropriate than the LSTM model.
摘要 本研究旨在根据 2017 年 10 月 26 日至 2023 年 3 月 31 日的 ESG 指数数据预测印度的 ESG(环境、社会和治理)回报波动。在本研究中,我们利用 GARCH(广义自回归条件异方差)和 LSTM(长短期记忆)模型预测 ESG 波动率的回报率,并评估模型的预测适用性。研究结果表明,在 ESG 波动率回报数据中存在 GARCH 效应,表明波动率的发生是对市场波动的反应。这项研究为波动预测模型的适用性提供了启示。此外,基于对 ESG 指数回报波动性的分析,GARCH 模型比 LSTM 模型更合适。

Abstract The significance of digital investment has grown substantially, enabled by advancing technology, which provides digital monitoring of investment instruments. Consequently, analyzing these instruments has become imperative. In particular, investors are inclined to compare new investment opportunities with well-established global stock markets, seeking to capitalize on their advanced financial literacy. This study aims to employ econometric analysis to explore the dynamic relationship between Bitcoin and the BIST100 and NASDAQ 100 indices. The time frame for this investigation spans from January 1, 2017, to March 10, 2022. Stationarity was confirmed through unit root tests (ADF, PP, KPSS, ZA, FADF, and FFFFF ADF) for the subsequent utilization of Autoregressive Conditional Variance Models. Additionally, Generalized Autoregressive Conditional Variance and Dynamic Conditional Correlation Tests were conducted. Results from the Dynamic Conditional Correlation Test model revealed no statistically significant dynamic conditional correlation between Bitcoin and BIST 100. Conversely, a negative and significant dynamic conditional correlation emerged between Bitcoin and NASDAQ 100. Investors should not only monitor the market but also review academic studies before making investment decisions. In this regard, this study holds significant importance. The study is limited to the BTC, BIST, and NASDAQ indices. Researchers interested in the topic can increase the dataset to further enrich the study.
摘要 数字投资的重要性已大大增加,这得益于提供投资工具数字监控的先进技术。因此,对这些工具进行分析已成为当务之急。特别是,投资者倾向于将新的投资机会与成熟的全球股票市场进行比较,以寻求利用其先进的金融知识。本研究旨在采用计量经济学分析方法,探讨比特币与 BIST100 指数和纳斯达克 100 指数之间的动态关系。本次调查的时间跨度为 2017 年 1 月 1 日至 2022 年 3 月 10 日。通过单位根检验(ADF、PP、KPSS、ZA、FADF 和 FFFFF ADF)确认了静态性,随后使用自回归条件方差模型。此外,还进行了广义自回归条件方差和动态条件相关性检验。动态条件相关性检验模型的结果显示,比特币与 BIST 100 之间没有统计意义上的显著动态条件相关性。相反,比特币与纳斯达克 100 指数之间出现了显著的负动态条件相关性。投资者在做出投资决策之前,不仅要关注市场,还要回顾学术研究。在这方面,本研究具有重要意义。该研究仅限于 BTC、BIST 和纳斯达克指数。对该主题感兴趣的研究人员可以增加数据集,进一步丰富研究内容。

How COVID-19 Affected Corporate Dividend Decisions: Novel Evidence from Emerging Countries COVID-19 如何影响企业股息决策?来自新兴国家的新证据
Pub Date : 2023-12-01 DOI: 10.2478/fiqf-2023-0025

Abstract The study aims to investigate the corporate dividend policy decisions in emerging countries during the COVID-19 pandemic. Our sample consists of 5,869 publicly listed firms from 29 emerging countries to explicate the observed trends in dividend policy during the pandemic. Logistic regressions are used to investigate the main factors that drive the propensity to change dividend payouts. Our analysis reveals that most firms opted to either increase or decrease their dividends, with a minority proportion deciding to maintain dividends. Notably, our findings demonstrate that firm profitability is the main driver of all types of dividend changes, except when firms opt to maintain or decrease dividends. Moreover, we find that when firms reduce dividends by over 70%, profitability emerges as a crucial determinant, thus bolstering the signaling hypothesis. The results are robust to sample size sensitivity and different levels of dividend changes. The findings of the study might have practical implications for corporate managers and policymakers in designing dividend decisions and policies under uncertain conditions. This research underscores the impact of the COVID-19 pandemic on corporate dividend policy in emerging countries and emphasizes the need to consider the level of dividend changes in exploring the dividend puzzle.
摘要 本研究旨在调查 COVID-19 大流行期间新兴国家的公司股利政策决策。我们的样本包括来自 29 个新兴国家的 5,869 家上市公司,以解释在大流行病期间观察到的股利政策趋势。我们使用逻辑回归法来研究驱动股利支付倾向变化的主要因素。我们的分析表明,大多数公司选择增加或减少股息,只有少数公司决定维持股息。值得注意的是,我们的研究结果表明,除企业选择维持或减少股息外,企业盈利能力是所有类型股息变化的主要驱动因素。此外,我们还发现,当企业减少股息超过 70% 时,盈利能力成为关键的决定因素,从而支持了信号传递假说。研究结果对样本量的敏感性和股息变化的不同水平都是稳健的。研究结果可能对企业管理者和政策制定者在不确定条件下设计股利决策和政策具有实际意义。本研究强调了 COVID-19 大流行对新兴国家企业股利政策的影响,并强调了在探索股利之谜时考虑股利变化水平的必要性。

Abstract Efficiency of education expenditure is the ability to maximize the educational achievement given the resources invested. Although public education expenditure tends to increase, yet this does not necessarily guarantee high quality of education services. This study aims to assess public education expenditure efficiency of Lithuanian municipalities and to identify the factors explaining its variations. The study used data for 2013-2019 from 60 Lithuanian municipalities. Corrected Ordinary Least Squares method was employed for public education expenditure efficiency assessment and regression analysis was used to determine its influencing factors. Inputs included financial (public expenditure for education and maintenance) and nonfinancial (composition of teachers, occupied area, etc.) variables. Passing ratio of Lithuanian (national) language and math exams were used as efficiency outputs. The context variables represented environmental factors of educational achievements, such as number of business entities, users of social housing, libraries, and culture centres as well as municipalities’ overall financial autonomy. Results of the research are ambiguous. When assessed by the overall passing of the exams, the efficiency was high, scoring 86-90%. But when evaluated by passing exams with the highest scores, it did not even reach 40%. Two types of public expenditure were identified as the most influential factors - public expenditure for education with the negative trend, and municipality own financing with the positive influence on the public education expenditure efficiency. Such results support the decentralization of public education expenditure management and call for alternative output measures in the Lithuanian public education system.
摘要 教育支出的效率是指在投入资源的情况下最大限度地提高教育成果的能力。虽然公共教育支出呈增长趋势,但这并不一定能保证教育服务的高质量。本研究旨在评估立陶宛各市的公共教育支出效率,并找出解释其变化的因素。研究使用了立陶宛 60 个城市 2013-2019 年的数据。采用修正普通最小二乘法进行公共教育支出效率评估,并使用回归分析确定其影响因素。输入变量包括财务变量(用于教育和维护的公共支出)和非财务变量(教师构成、占用面积等)。立陶宛(国家)语文和数学考试的通过率被用作效率产出。环境变量代表教育成果的环境因素,如商业实体、社会住房用户、图书馆和文化中心的数量以及市政当局的整体财政自主权。研究结果模棱两可。如果以考试的总体通过率来评估,效率很高,达到 86-90%。但如果以最高分通过考试来评估,效率甚至达不到 40%。有两类公共支出被认为是最有影响的因素,一类是公共教育支出,呈负增长趋势;另一类是市政当局的自有资金,对公共教育支出效率有积极影响。这些结果支持公共教育支出管理的权力下放,并呼吁立陶宛公共教育系统采取其他产出措施。

Abstract Diversity within top management teams (TMTs) has significant implications for firm financial performance, particularly in dynamic industries like the automotive sector. This paper analyzes the relationship between TMT diversity and financial outcomes in companies associated with the Volkswagen Group, operating in an intensely competitive market marked by technological advancements. This comprehensive paper synthesizes studies investigating the correlation between TMT diversity and financial performance within the automotive domain. Employing quantitative approaches, these studies assess demographic factors such as gender, age, ethnicity, and educational background. The analysis unveils distinct patterns of impact. Gender diversity within TMTs exhibits a positive influence on financial performance, with heightened profitability and increased market value being notable outcomes. Age diversity shows a nuanced trend, with moderate levels enhancing strategic decision-making capabilities and fostering innovation. Increased ethnic diversity within TMTs is associated with elevated innovation and overall firm performance. Furthermore, educational diversity within TMTs is found to bolster firm performance, underscoring its pivotal role in strategic decision-making and innovation. By offering a comprehensive synthesis of TMT diversity’s connection to financial performance within the Volkswagen Group’s context, this paper contributes novel perspectives. The study emphasizes the methodologies utilized, outlines key findings, and underscores the original contributions made by existing research. This study illuminates the profound influence of TMT diversity on shaping strategic decisions and fostering innovation in the automotive sector. Importantly, it highlights the crucial role of TMT diversity in driving positive financial outcomes.

Abstract In Turkey, the housing market is affected by various factors, and housing prices are shaped according to current conditions. In this study, the relationship between the housing price index (HPI) and economic variables (inflation and exchange rate) in Turkey was investigated. We used a 10-year time period for this study, from January-2010 to December-2019, with monthly data frequency. For our research, we employ the Wavelet Coherence Transformation (WCT) method. The results show that there is a positive relationship between inflation and housing prices in the short and long run. In addition, a continuous rise in inflation led to an increase in housing prices all over the period from 2010 to 2019. The findings of this study can aid in achieving the goal of the research by offering evidence-based perceptions of how housing prices and different economic variables are related. Housing costs in Turkey increased as a result of the substantial likelihood that the Turkish lira would weaken. The expansion of global inflation is a further anticipated factor contributing to the rise in housing costs in Turkey. This study can also be used by investors to help them decide whether to engage in the Turkish real estate industry.
在土耳其,住房市场受到各种因素的影响,房价是根据当前情况形成的。在这项研究中,住房价格指数(HPI)和经济变量(通货膨胀和汇率)在土耳其的关系进行了调查。我们在这项研究中使用了10年的时间周期,从2010年1月到2019年12月,每月数据频率。在我们的研究中,我们采用小波相干变换(WCT)方法。结果表明,通货膨胀与房价在短期和长期都存在正相关关系。此外,通货膨胀的持续上升导致房价在2010年至2019年期间一直在上涨。本研究的发现可以通过提供基于证据的房价和不同经济变量如何相关的看法来帮助实现研究的目标。由于土耳其里拉极有可能贬值,土耳其的住房成本增加了。全球通货膨胀的扩大是预计土耳其住房成本上升的另一个因素。本研究也可以被投资者用来帮助他们决定是否从事土耳其房地产行业。

The results show that there is a positive relationship between inflation and housing prices in the short and long run. In addition, a continuous rise in inflation led to an increase in housing prices all over the period from 2010 to 2019. The findings of this study can aid in achieving the goal of the research by offering evidence-based perceptions of how housing prices and different economic variables are related. Housing costs in Turkey increased as a result of the substantial likelihood that the Turkish lira would weaken. The expansion of global inflation is a further anticipated factor contributing to the rise in housing costs in Turkey. This study can also be used by investors to help them decide whether to engage in the Turkish real estate industry.","PeriodicalId":213695,"journal":{"name":"Financial Internet Quarterly","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135641331","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 Emerging nations are often distressed if their current administration and governance do not align with social and national needs. Among these worries, there is the fear of public funds misconduct and corruption in the nation’s major institutions. Indeed, inadequate administration results in embezzlement of funds, tax evasion, and low bureaucratic quality in all sectors. This study was undertaken to address the role of impartial administration specifically in the financial sector. The research considered a sample size composed of 12 countries from Latin America and Sub-Saharan Africa in the period of 2000 to 2021. The net interest margin was considered a proxy for financial performance measurement. Additionally, an ordinary least squares and quantile regression was performed to record the effect of the variables on financial sector performance. Within this context, the findings exhibited different outcomes for these regions. For instance, in the Latin America region, the results revealed that public sector theft, bureaucratic quality, corruption level, local government index, and inflation have a negative impact on the performance of the financial sector while impartial public administration demonstrated a positive impact on financial performance. On the other hand, the Sub-Saharan African region demonstrated that bureaucratic quality, local government index, and inflation have a significant and positive impact on financial performance, whereas executive embezzlement and theft, corruption level, and government final expenditures were shown to negatively influence financial performance. Finally, the study’s findings provides insights into the policies and strategies to implement in order to support the financial framework.
新兴国家如果目前的行政和治理不符合社会和国家的需要,往往会感到苦恼。在这些担忧中,人们担心公共资金的不当使用和国家主要机构的腐败。事实上,管理不善导致了挪用资金、逃税和各部门官僚素质低下。进行这项研究的目的是讨论公正行政的作用,特别是在金融部门。该研究考虑了2000年至2021年期间来自拉丁美洲和撒哈拉以南非洲的12个国家的样本量。净息差被认为是衡量财务业绩的一个指标。此外,进行了普通最小二乘和分位数回归,以记录变量对金融部门绩效的影响。在此背景下,研究结果显示了这些地区的不同结果。例如,在拉丁美洲地区,结果显示,公共部门盗窃、官僚质量、腐败程度、地方政府指数和通货膨胀对金融部门的绩效产生负面影响,而公正的公共行政对财务绩效产生积极影响。另一方面,撒哈拉以南非洲地区表明,官僚质量、地方政府指数和通货膨胀对财务绩效有显著的正向影响,而高管贪污和盗窃、腐败程度和政府最终支出对财务绩效有负向影响。最后,研究结果为支持金融框架所需实施的政策和战略提供了见解。

Polish household default risk and physical risk of climate change 波兰家庭违约风险和气候变化的物理风险
Pub Date : 2023-09-01 DOI: 10.2478/fiqf-2023-0021

Abstract This paper aims to assess the level of credit risk (from the perspective of default risk) among Polish households associated with the physical risks of climate change. In order to determine the potential impact of the physical risk of climate change on household credit risk, we conducted CAWI interviews with 1,006 borrowers residing in different Polish voivodeships (to account for heterogeneity of credit exposures to extreme weather events). According to these respondents, wildfires and storms in Poland are the greatest source of physical risk of climate change. In the event of a wildfire or storm, approximately 13% of borrowers would not be able to repay their loans while not being insured, which potentially increases banks’ credit risk and exposes banks to losses. However, we find that households underestimate the credit risk that could arise from a drought.
本文旨在评估波兰家庭与气候变化物理风险相关的信用风险水平(从违约风险的角度)。为了确定气候变化物理风险对家庭信贷风险的潜在影响,我们对居住在波兰不同省份的1,006名借款人进行了CAWI访谈(以解释极端天气事件信贷风险的异质性)。根据这些受访者的说法,波兰的野火和风暴是气候变化的最大物理风险来源。如果发生野火或风暴,大约13%的借款人在没有投保的情况下将无法偿还贷款,这可能会增加银行的信贷风险,并使银行面临损失。然而,我们发现家庭低估了干旱可能带来的信贷风险。

An assessment of the risk mitigating factors in Ghana’s Bank Industry 加纳银行业风险缓解因素的评估
Pub Date : 2023-09-01 DOI: 10.2478/fiqf-2023-0019

Abstract To maintain financial stability, banks need to recognize, assess, and mitigate potential losses, thus making risk control critical for long-term profitability as well as avoiding unexpected losses. This research examines the risk mitigating factors and performance of Ghanaian domestic banks in terms of capital adequacy, bank size, bank efficiency, and profitability, along with their association with systemic risk in the bank sector, as measured by the Z-score: Insolvency Risk - (µROA) plus capital asset ratio (equity capital divided by sum of all assets further divided by the standard deviation-(ƠROA) with a higher score for banks as a measure of bank stability. The study further explores the relationship between this ratio and the explanatory variables for a sample of 11 banks operating in Ghana between 2010 and 2021. Analysis of the data using the fixed effects model shows that profitability and bank efficiency are significant and affect the stability of banks positively. Bank size, on the other hand, is significant but negatively affects the stability of banks. Bank profitability is critical to stabilizing and protecting the banking sector from external shocks; as a result, this study suggests that bank management apply prudent practices to profitability-driven indicators and that the banking sector regulations be congruent with macro-prudential policies.
为了维持金融稳定,银行需要识别、评估和减轻潜在损失,因此风险控制对于长期盈利和避免意外损失至关重要。本研究考察了加纳国内银行在资本充足率、银行规模、银行效率和盈利能力方面的风险缓解因素和表现,以及它们与银行部门系统性风险的关联,用z分数来衡量:破产风险(µROA)加上资本资产比率(权益资本除以所有资产的总和,再除以标准差)(ƠROA),作为银行稳定性的衡量标准,银行的得分较高。本研究以2010年至2021年间在加纳经营的11家银行为样本,进一步探讨了这一比率与解释变量之间的关系。利用固定效应模型对数据进行分析,发现盈利能力和银行效率显著,并对银行的稳定性产生正向影响。另一方面,银行规模是显著的,但对银行的稳定性有负面影响。银行盈利能力对于稳定和保护银行业免受外部冲击至关重要;因此,本研究建议银行管理层对盈利能力驱动的指标采取谨慎的做法,银行业监管应与宏观审慎政策相一致。
