Abstract An important feature of every financial system throughout history is its capability to facilitate transfer of money in a secure and cost efficient manner. Cryptocurrencies as sources of innovative solutions – especially Bitcoin as their most prominent representative – have offered a completely new transmission system for a piece of information that can contain and carry value. There are many approaches to evaluate (un)successfulness of Bitcoin as money, and arguably one of the most important is to assess the fulfilment of its inventor’s original proposition: can it be used to send money directly and securely abroad, to international destinations, without fear of double-spending? Moreover, by removing institutions and their fees from the system hierarchy, can it be done for a lower price? The objective of creating Bitcoin network (among others) was to promote democratization of finance by enabling monetary transactions over the internet without unnecessary intermediaries inserting and charging multiple layers of fees. In decentralized, distributed blockchains such as Bitcoin and Ethereum subjects are incentivized to collectively maintain the public ledger (blockchain) by collecting block rewards (“coinbase”) and transaction fees. Block-chain maintenance is known as mining, and miners are compensated for their effort in the form of fees (and coinbase rewards) for verifying transactions. The objective of this paper is to examine and compare fees for transferring money internationally by means of Bit-coin network, in contrast to using traditional pathways, mostly banks, and in this manner to scrutinize the proof of concept and one of the cryptocurrency solutions to the issue of money transfer. By doing so we are attempting to provide answers to the questions of functionality and cost-effectiveness of an alternative financial system based on the blockchain technology. Transaction fees for international payments made by Bitcoin are compared by analysing a novel dataset obtained from World Bank and Croatian National Bank (CNB). CNB’s data is not publicly available, and was attained for this paper specifically. It contains 1.400 types of fees charged by the 23 banks operating in Croatia for the period of October 2018 to February 2022. Bank fees for international transactions were matched with Bitcoin fees in the same period, with the data taken from Blockchain.com online service. On average, to send 1,000 USD abroad by using Bitcoin network required approx. three times less in fees than by using banks in Croatia. The calculation structure of bank fees, also presented in the paper, required higher costs for sending lower amounts (in terms of percentage); when transferring 200 USD banks worldwide charged on average approx. 30 times more in fees than Bitcoin miners. Additionally, transaction fees for international remittances were analysed with quarterly data from World Bank. Comparative analysis of these and Bitcoin fees was made, and it is clear
摘要历史上每一个金融系统的一个重要特征是它能够以安全和成本效益的方式促进资金转移。加密货币作为创新解决方案的来源,尤其是比特币作为其最突出的代表,为一条可以包含和携带价值的信息提供了一个全新的传输系统。有很多方法可以评估比特币作为货币的(不)成功性,可以说最重要的方法之一是评估其发明者最初主张的实现情况:它可以用来直接安全地将资金发送到国外、国际目的地,而不用担心双重支出吗?此外,通过将机构及其费用从系统层级中删除,可以以更低的价格实现吗?创建比特币网络(除其他外)的目的是通过在互联网上进行货币交易来促进金融民主化,而无需不必要的中介机构插入和收取多层费用。在去中心化的分布式区块链中,比特币和以太坊等主体被激励通过收取区块奖励(“coinbase”)和交易费用来集体维护公共账本(区块链)。区块链维护被称为挖矿,矿工的努力将以验证交易的费用(和coinbase奖励)的形式得到补偿。本文的目的是检查和比较通过比特币网络在国际上转账的费用,与使用传统途径(主要是银行)形成对比,并以这种方式检查概念验证和货币转账问题的加密货币解决方案之一。通过这样做,我们试图为基于区块链技术的替代金融系统的功能和成本效益问题提供答案。通过分析从世界银行和克罗地亚国家银行获得的一个新数据集,比较了比特币国际支付的交易费用。CNB的数据没有公开,是专门为本文获得的。它包含2018年10月至2022年2月期间在克罗地亚运营的23家银行收取的1400种费用。同期,国际交易的银行费用与比特币费用相匹配,数据来自Blockchain.com在线服务。平均而言,使用比特币网络向国外发送1000美元所需的费用大约是使用克罗地亚银行的三倍。文件中也提出了银行手续费的计算结构,要求发送较低金额的费用较高(按百分比计算);当转移200美元时,全球银行平均收取的费用是比特币矿工的30倍。此外,还利用世界银行的季度数据分析了国际汇款的交易费用。对这些费用和比特币费用进行了比较分析,很明显,(平均而言)通过比特币网络向国外汇款对最终用户来说成本要低得多,尤其是在转账金额较低的情况下。由于基础变量分布的非正态性,应用了非参数检验,拒绝了交易成本具有相同中位数的零假设。总之,当需要在国际上转账时,用户可以通过使用去中心化技术(如比特币的区块链)获得显著更低的成本。这一发现验证了分布式账本的一个关键命题。比特币网络不是专注于比特币价格的日常剧烈波动及其波动,而是一个具有成本效益的国际支付系统,并证明自己是传统汇款方案的替代方案。

Abstract In the context of current deglobalization trends this research aims to investigate the need for changes in tourism supply system by analysing perception and expectations of procurement managers and suppliers of goods and services related to growing inflationary pressure on business costs and raising concerns about vulnerability and instability of the global supply chains. Based on survey and semi-structured interviews conducted among hotel procurement managers and local suppliers in popular seaside tourism destinations in Croatia, this research provides empirical evidences of the necessity to strengthen local capacities for the production of goods and service delivery using local resources in accordance to the principles of sustainable tourism development. The greatest concern respondents showed regarding the rising prices of energy, which was expected due to actual political situation in Europe. Study also provides some policy recommendations for ‘reinventing’ local production of goods and services for tourism-related purposes.
在当前去全球化趋势的背景下,本研究旨在通过分析采购经理和商品和服务供应商对商业成本日益增长的通胀压力的看法和期望,以及对全球供应链脆弱性和不稳定性的担忧,来调查旅游供应系统变革的必要性。基于对克罗地亚热门海滨旅游目的地的酒店采购经理和当地供应商进行的调查和半结构化访谈,本研究提供了经验证据,证明有必要根据可持续旅游发展的原则,加强利用当地资源生产商品和提供服务的当地能力。受访者最担心的是能源价格的上涨,这是由于欧洲的实际政治局势所预料到的。研究亦提供了一些政策建议,以“再造”本地生产与旅游有关的商品和服务。

The Darker Side of Fintech: the Emergence of New Risks 金融科技的黑暗面:新风险的出现

Abstract The financial sector has always been recognized as a traditional activity. One of the biggest challenges facing the financial sector recently is the introduction of new technologies. Financial innovations, and especially the development of financial technologies (FinTech), contribute to changing the way the entire financial system, including the banking sector, changes in the digital economy. The changes brought about by financial innovations and technologies condition all market participants, and especially banks, to continuously improve their business in order to keep up with the competition. FinTech enable easier access to financial services, improvement of traditional services, provide greater efficiency, lower costs and automation of regulatory reporting. They have changed the way we perceive financial institutions. Banks can increasingly be seen as an application on the phone and computer through which financial services can be performed, less and less as a grand building that instils confidence. However, it should be borne in mind that the application of financial innovations, in addition to the advantages, carries with it many risks, in a way that it can be said that digital technologies change existing ones, but also bring new risks in the field of financial services. The key risks caused by these technologies include strategic, operational and cyber risk, the risk of business compliance with data protection regulations, as well as liquidity risk. The importance of outsourcing risk is not negligible. It is precisely because of the speed of change and innovation that new risks are constantly emerging. With the growing importance and number of these firms, as well as the speed of their cross-border transactions, the fact is that it is necessary that these firms must adjust the way they measure risk in accordance with the speed and pace of their development. The importance of risk management must be one of the key points for FinTech companies, both now and in the future. Due to the observation of advances in financial technologies and the assessment of the risks that financial innovations bring, there is a need to harmonize regulatory frameworks, in order to ensure that none of the financial service providers would be at a disadvantage. However, regulatory bodies must carefully consider the dynamics and manner of regulation, bearing in mind that in a rapidly changing environment, excessive and rapid regulation carries the risk of undesirable outcomes in a way that does not exploit the full potential of innovative technologies. The development and increasing use of financial technologies affects the activities of all participants in the financial market, which imposes the need for continuous learning and adaptation of users and providers of these services, as well as supervisors and regulators. An additional challenge for financial institutions is the fact that competition in the provision of financial services comes from IT compani
摘要金融部门一直被认为是一项传统活动。金融部门最近面临的最大挑战之一是引入新技术。金融创新,尤其是金融技术(FinTech)的发展,有助于改变包括银行业在内的整个金融系统在数字经济中的变化方式。金融创新和技术带来的变化要求所有市场参与者,尤其是银行,不断改进业务,以跟上竞争。金融科技使人们更容易获得金融服务,改善传统服务,提高效率,降低成本,实现监管报告自动化。它们改变了我们对金融机构的看法。银行越来越被视为手机和电脑上的一个应用程序,通过它可以提供金融服务,而越来越不被视为灌输信心的宏伟建筑。然而,应该记住的是,金融创新的应用除了带来优势外,还带来了许多风险,可以说,数字技术改变了现有技术,但也给金融服务领域带来了新的风险。这些技术造成的关键风险包括战略、运营和网络风险、业务遵守数据保护法规的风险以及流动性风险。外包风险的重要性不容忽视。正是由于变革和创新的速度,新的风险不断出现。随着这些公司的重要性和数量以及跨境交易的速度不断增加,这些公司必须根据其发展的速度和步伐调整衡量风险的方式。风险管理的重要性必须是金融科技公司现在和未来的关键点之一。鉴于对金融技术进步的观察和对金融创新带来的风险的评估,有必要协调监管框架,以确保没有一家金融服务提供商处于不利地位。然而,监管机构必须仔细考虑监管的动态和方式,牢记在快速变化的环境中,过度和快速的监管会带来不良结果的风险,而这种风险并没有充分利用创新技术的潜力。金融技术的发展和日益使用影响到金融市场所有参与者的活动,这就要求这些服务的用户和提供者以及监管者和监管者不断学习和适应。金融机构面临的另一个挑战是,提供金融服务的竞争来自IT公司,这必然要求调整其商业模式。金融机构正面临着最大的商业挑战之一。所有这些都给监管标准的制定者(RegTech)和基于新技术的监管的发展带来了特殊的挑战(SupTech)。

Abstract The service quality literature focusing on higher education has been expanding rapidly parallel with the increasing marketization of the sector which poses new challenges against institutional improvement efforts and the applied management toolkit. The primary objective of our paper is to demonstrate the results of a surveying carried out in the Hungarian higher education system. The participating students evaluated the importance of quality attributes that were previously defined at the programme and the institution levels of operation and also rated the performance they had experienced along the same attributes. Both the quantitative and the qualitative results demonstrate that the student perceptions about the institutional image primarily stem from their service quality perceptions gained at the programme level defining the total student experience. Therefore, the institutional actions aiming service quality improvements should incorporate the programme level experiences of students both for enhancing total student satisfaction and institutional reputation.
随着高等教育市场化程度的提高,有关高等教育服务质量的文献也在迅速扩大,这对制度改进和应用管理工具提出了新的挑战。本文的主要目的是展示在匈牙利高等教育系统中进行的一项调查的结果。参与的学生评估了先前在课程和机构层面上定义的质量属性的重要性,并对他们在相同属性上的表现进行了评分。定量和定性结果都表明,学生对机构形象的看法主要源于他们在项目层面获得的服务质量看法,这决定了学生的总体体验。因此,旨在改善服务质量的机构行动应纳入学生的课程水平经验,以提高学生的总体满意度和机构声誉。

Abstract This paper analyses household financial fragility during the COVID-19 pandemic. Considering the barging theory in households’ decision-making, this paper proposes that women’s financial literacy and their involvement in paid and unpaid work will influence family financial fragility in times of crisis. The results show that women’s financial literacy, their participation in the labour market, and their financial independence have a significant and positive effect on the family’s financial situation during the pandemic. Moreover, the level of women’s unpaid work was identified as a significant element that jeopardizes family financial stability. The results further support the bargaining power theory regarding a better understanding of the complexity of decision-making within households. The results point to a new channel for preserving family financial stability, through the improvement of women’s financial literacy and the development of institutional and social support for their participation in the labour market.
摘要本文分析了新冠肺炎大流行期间的家庭财务脆弱性。考虑到家庭决策中的讨价还价理论,本文提出,在危机时期,女性的财务知识及其参与有偿和无偿工作将影响家庭财务脆弱性。研究结果表明,在疫情期间,妇女的金融知识、参与劳动力市场以及经济独立性对家庭经济状况产生了重大而积极的影响。此外,妇女的无偿工作水平被认为是危害家庭财务稳定的一个重要因素。研究结果进一步支持了议价能力理论,即更好地理解家庭内部决策的复杂性。结果表明,通过提高妇女的金融知识以及为她们参与劳动力市场提供体制和社会支持,为维护家庭金融稳定开辟了一条新渠道。

Abstract This paper aims to identify performance differences between conventional European equity indices and ESG indices. Conventional European equity indices are tools both institutional and retail investors use to understand the overall state of the market, as well as a benchmark for comparing investment decisions. ESG indices or sustainability indices are different from conventional market indices and can provide information to investors about the firm’s sustainability performance, they are new and constantly developing stock market indices taking into account environmental, social, and governance considerations. The indices were analysed by multivariate analysis. Since we could collect data by country only for conventional indices, cluster analysis based only on those indices was performed. The following variables of conventional indices were analysed: year-to-date price return, annualized 3-year price return, annualized 5-year price return, and annualized 10-year price return. The paper also compares ESG indices and conventional indices, and in most cases, they have no significant performance differences.
摘要本文旨在确定传统欧洲股票指数与ESG指数之间的绩效差异。传统的欧洲股指是机构投资者和散户投资者用来了解市场整体状况的工具,也是比较投资决策的基准。ESG指数或可持续性指数不同于传统的市场指数,可以向投资者提供有关公司可持续发展绩效的信息,它们是考虑到环境,社会和治理因素的新兴和不断发展的股票市场指数。采用多变量分析对指标进行分析。由于我们只能按国家收集常规指数的数据,因此只能基于这些指数进行聚类分析。对传统指数的年度价格收益率、3年年化价格收益率、5年年化价格收益率、10年年化价格收益率进行了分析。本文还对ESG指数与传统指数进行了比较,在大多数情况下,它们的绩效没有显著差异。

The Impact of ECB’s Unconventional Monetary Policy on the German Stock Market Volatility 欧洲央行非常规货币政策对德国股市波动的影响

Abstract This study investigated the reaction of German stock market volatility (Dax index) to the European Central Bank (ECB)’s unconventional monetary policy (UMP) announcements. The financial crisis of 2008 proved that the traditional monetary policy’s tool (the short -term interest rate) has lost its effectiveness to meet the new challenges. So, the key central banks, ECB included, had to implement the new, untested and nonstandard monetary policy which so called unconventional monetary policy. In this study, we used the ECB’s shadow policy rate approach to extract unconventional monetary policy. Also, We employed GJR GARCH (p,o,q) model to estimate the volatility in the German stock market. Then we calibrated both OLS (linear regression) and Markov-switching (probability-matrix of regime changes) models to examine the reaction of German stock returns volatility to UMP announcement by ECB for a period from January 2006 to December 2019. The results delivered by both models showed that the ECB’s UMP had a strong and negative effect on the volatility of the German stock market. Also, both models showed that the past German stock volatility has a significant and negative effect on the dependent variable, while the volatility of the German stock returns is a function of the global volatility estimated by the VIX index. Moreover, the results showed that the Markov-switching regression model provides a better illustration of the stock market volatility impact of UMP than the OLS model because it can represent the changes into the two different regimes named ordinary regime and quantitative easing (crisis) regime. Furthermore, under the Markov-switching regression model, we can see how the output gap and the inflation gap influence the volatility of the Dax index, while the results of the OLS regression model showed that there is no significant relationship between the output gap and the inflation gap with the German stock market volatility.
摘要本研究调查了德国股市波动率(Dax指数)对欧洲央行(ECB)非常规货币政策(UMP)公告的反应。2008年的金融危机证明,传统的货币政策工具(短期利率)已经失去了应对新挑战的有效性。因此,包括欧洲央行在内的主要央行不得不实施新的、未经测试的、非标准的货币政策,即所谓的非常规货币政策。在这项研究中,我们使用了欧洲央行的影子政策利率方法来提取非常规货币政策。此外,我们还采用GJR-GARCH(p,o,q)模型来估计德国股市的波动性。然后,我们校准了OLS(线性回归)和Markov切换(制度变化概率矩阵)模型,以检验2006年1月至2019年12月期间德国股票回报率波动对欧洲央行UMP公告的反应。两个模型的结果都表明,欧洲央行的UMP对德国股市的波动性产生了强烈的负面影响。此外,这两个模型都表明,过去德国股票的波动性对因变量有显著的负面影响,而德国股票回报的波动性是VIX指数估计的全球波动性的函数。此外,结果表明,马尔可夫切换回归模型比OLS模型更好地说明了UMP对股市波动的影响,因为它可以代表普通制度和量化宽松(危机)制度这两种不同制度的变化。此外,在Markov切换回归模型下,我们可以看到产出缺口和通胀缺口如何影响Dax指数的波动,而OLS回归模型的结果表明,产出缺口和通货膨胀缺口与德国股市波动没有显著关系。

The financial crisis of 2008 proved that the traditional monetary policy’s tool (the short -term interest rate) has lost its effectiveness to meet the new challenges. So, the key central banks, ECB included, had to implement the new, untested and nonstandard monetary policy which so called unconventional monetary policy. In this study, we used the ECB’s shadow policy rate approach to extract unconventional monetary policy.

Modelling CESEE Countries Export Dynamics: Global Vector Autoregressive Approach CESEE国家出口动态建模:全局向量自回归方法

Abstract One of the main aspects of the transition process in Central, Eastern and Southeastern European (CESEE) countries was the trade liberalisation. As their financial systems are still underdeveloped and the trade channel is the dominant shock transmitter, this paper focuses on export dynamics for a selected set of CESEE countries. The employed methodology, Global Vector Autoregressive (GVAR) approach, allows modelling interactions and spillovers among countries. Furthermore, it enables joint modelling of exports and imports. This is of particular importance as the opening of new markets enabled astonishing export growth, but also opened the CESEE markets to foreign products. The empirical analysis reveals that a shock in German imports has a larger impact on CESEE countries’ exports than a shock in German output. Moreover, the results indicate that the role of the real exchange rate is less pronounced in comparison to previous similar research.
摘要中欧、东欧和东南欧国家转型过程的主要方面之一是贸易自由化。由于这些国家的金融体系仍然不发达,贸易渠道是主要的冲击传导者,本文重点关注了一组选定的经济、社会和经济发展经济区国家的出口动态。所采用的方法,即全球向量自回归(GVAR)方法,允许对国家之间的互动和溢出进行建模。此外,它还能够对出口和进口进行联合建模。这一点尤为重要,因为新市场的开放带来了惊人的出口增长,但也向外国产品开放了CESEE市场。实证分析表明,德国进口的冲击对经济、社会和经济发展经济区国家出口的影响大于德国产出的冲击。此外,研究结果表明,与以前的类似研究相比,实际汇率的作用不那么明显。

Abstract We understand that atypical employment can be sustained if it provides benefits for both the employer and the employee, but these benefits, in most cases, have only an indirect effect on profit. This study examines whether workers with fixed-term employment could be more effective regarding certain performance indicators than their co-workers with indefinite employment contracts. Results show that in one of the two examined performance indicators (number of clients served), individuals working in an atypical form of employment are more efficient for almost all variables, while for the second performance indicator (value creation), they are not more efficient for either of the variables.
摘要我们知道,如果非典型就业为雇主和雇员都提供福利,那么它是可以持续的,但在大多数情况下,这些福利对利润只有间接影响。这项研究考察了定期雇佣的工人在某些绩效指标上是否比无限期雇佣合同的同事更有效。结果表明,在两个考察的绩效指标之一(服务的客户数量)中,在非典型就业形式下工作的个人对几乎所有变量都更有效率,而在第二个绩效指标(价值创造)中,他们对任何一个变量都没有更高的效率。

Abstract This study explores the association between earning management practices and financial distress in commercial banks. Earning management is measured through discretionary loan loss provisions and non-discretionary loan loss provisions. Modified Altman’s Z-score has been used as a proxy for financial distress. Panel regression with fixed and random effect has been employed for empirical analysis. The study finds a significant positive association between DLLP, NDLLP and financial distress in terms of the Altman Z-score. In the case of NDLLP, liquidity reduces the probability of financial distress. Whereas, a bank’s SIZE, LEVG and AQ enhance the likelihood of financial distress. The robustness tests were applied to find the association between NDLLP and FD using logistic regression to validate baseline estimates results of the random effect model. The findings of this study have implications for the policymakers, regulators and internal stakeholders to devise effective regulatory measures for well-informed investment decisions.
摘要本研究探讨了商业银行盈余管理实践与财务困境之间的关系。盈利管理是通过可自由支配的贷款损失准备金和非可自由支配贷款损失准备金来衡量的。修改后的奥特曼的Z分数被用作财务困境的指标。采用具有固定和随机效应的面板回归进行实证分析。研究发现,就Altman Z评分而言,DLLP、NDLLP与财务困境之间存在显著的正相关。在NDLLP的情况下,流动性降低了财务困境的概率。然而,银行的SIZE、LEVG和AQ会增加财务困境的可能性。稳健性检验用于发现NDLLP和FD之间的关联,使用逻辑回归来验证随机效应模型的基线估计结果。这项研究的结果对政策制定者、监管机构和内部利益相关者制定有效的监管措施以做出明智的投资决策具有启示意义。
