Our aim in this paper is to design a set of fiscal policy rules using a linear, discrete macroeconomic Post-Keynesian model with delays. We develop algebraic methods with appropriate symbolic algorithms that produce a solution, which allows us to find a path for the desired GDP and debt targets to be met.   Keywords: Fiscal policy, Symbolic algorithmic methods, GDP, Debt, Algorithmic control JEL Classification: E00, E62, E12

The aim of this study is to explore the new International Standard on Audit (ISA) 701 “Communicating Key Audit Matters in the Independent Auditor´s Report”. More specifically, we examine Key Audit Matters (KAMs) in the first year of implementation in Greece, in 2017. We content analyze the audit reports to investigate the number and type of KAMs that are identified and disclosed by industry and by type of audit firm (i.e. Big-4, Crowe-Sol, Grant Thornton, and others). We hand-collect data from 153 audit reports of companies listed on the Athens Stock Exchange (ASE). Moreover, an empirical analysis is carried out to examine whether the size of the company being audited, and the type of the audit firm, affect the number of KAMs. Οur results show that the number of KAMs is positively related to the size and leverage of the audited company, as well as the tenure of the audit firm.    Key words: Key Audit Matters, ISA 700, ISA 701 JEL Classification: M41, M42, G38    
本研究的目的是探讨新的国际审计标准(ISA) 701“在独立审计师报告中传达关键审计事项”。更具体地说,我们将于2017年审查希腊实施第一年的关键审计事项(KAMs)。我们对审计报告进行内容分析,以调查按行业和审计事务所类型(即Big-4, Crowe-Sol, Grant Thornton等)确定和披露的kam的数量和类型。我们从雅典证券交易所(ASE)上市公司的153份审计报告中手工收集数据。此外,本文还进行了实证分析,以检验被审计公司的规模和审计公司的类型是否会影响kanm的数量。Οur结果显示,被审计公司的规模和杠杆率以及审计公司的任期与kam的数量呈正相关。关键词:关键审计事项,ISA 700, ISA 701 JEL分类:M41, M42, G38

Management and Quality Management Principles in Ancient Greece and their Reflection Today 古希腊的管理和质量管理原则及其在今天的反映
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5304
G. Aspridis, Louisa Poulianou, I. Koukoumpliakos
The work of ancient Greek philosophers is, to say the least, timeless, multifarious and continues to be cited all over the world. Among all issues they highlighted the significance of management and the way in which the State as well as private affairs were organized. This proves that the prevailing view arguing that Management Science is the result of the industrial revolution and especially in Anglo-Saxon countries is not consistent with reality. In ancient Greece the structure of city-states has proven that an effective management function had been established, and by extension its application to all aspects of public life as well. Xenophon is considered by many the father of Management Science. The Oeconomicus by Xenophon refers to the art of household management, while the definition of management is introduced as well. The Nicomachean Ethics by Aristotle is widely considered a classical work which could be taught today in the Faculties of Management and Economics and particularly emphasizes on ethics, leadership and education. Aristotle laid the foundations of the scientific method and introduced the definition of Science. Through the Socratic method (maieutics), Socrates is considered the philosopher who established the concept of guidance, and regards management as a special skill, distinct from experience and knowledge.  Plato referred to leadership and general culture as well as issues of ethics. Many political and military leaders (such as Cleisthenes, Miltiades, Thucydides, Solon and many others) engaged in state affairs management or took the lead in the military sector. The aim of the proposal under evaluation is to present the classical theories and the way they are incorporated into the modern management of both public and private sector in the era of globalization, multi-culturalism, diversity, electronic government and digital transformation. The proposal under evaluation has adopted the qualitative research method and specifically the tool of literature review. The aim is the holistic approach and analysis of the subject under research. Through the survey of literature, the researchers wish to present the timeless views on Management Science, as well as form new and modern ideas. For this reason, secondary publications relevant to the subject have been selected, such as the works of ancient Greek philosophers, studies, articles, reports, electronic books, texts from websites, etc. The conclusions of the proposal under evaluation are particularly significant and, whatever their utilization may be, can substantially contribute to the upgrading of Management Science in Greece. Ideally, these classical works could be taught in University Faculties at both undergraduate and postgraduate level.   JEL Classifications: M00, N01 Key words: Quality Management, Administrative Science, Ethics, Management, Education
古希腊哲学家的作品,至少可以说,是永恒的,五花八门的,并继续在世界各地被引用。在所有问题中,他们突出了管理的重要性以及组织国家和私人事务的方式。这证明了认为管理科学是工业革命的结果的主流观点,特别是在盎格鲁-撒克逊国家是不符合现实的。在古希腊,城邦的结构已经证明了一种有效的管理功能已经建立起来,并通过扩展,将其应用到公共生活的各个方面。色诺芬被许多人认为是管理科学之父。色诺芬的《经济学》指的是家庭管理的艺术,同时也介绍了管理的定义。亚里士多德的《尼各马可伦理学》被广泛认为是一部经典著作,今天可以在管理和经济学院教授,特别强调道德、领导和教育。亚里士多德奠定了科学方法的基础,引入了科学的定义。通过苏格拉底的方法(maieutics),苏格拉底被认为是建立指导概念的哲学家,并将管理视为一种不同于经验和知识的特殊技能。柏拉图提到了领导和一般文化以及道德问题。许多政治和军事领袖(如克利斯提尼、米提亚德、修昔底德、梭伦等)从事国家事务管理或领导军事部门。本次提案的目的是展示经典理论及其在全球化、多元文化、多样性、电子政府和数字化转型时代如何融入公共和私营部门的现代管理。被评估的提案采用了定性研究方法,特别是文献综述的工具。其目的是对研究对象进行整体分析。通过文献调查,研究者希望呈现出关于管理科学的永恒观点,并形成新的和现代的观点。因此,选择了与主题相关的二手出版物,例如古希腊哲学家的著作、研究、文章、报告、电子书、网站文本等。正在评估的提案的结论特别重要,无论如何加以利用,都可以大大有助于提高希腊的管理科学水平。理想情况下,这些经典作品可以在本科和研究生阶段的大学院系教授。JEL分类:M00, N01关键词:质量管理,行政科学,伦理学,管理学,教育

A Two-Phase Optimal Portfolio Selection Using Sharpe Index Model Applied to the Athens Stock Exchange 基于夏普指数模型的两阶段最优投资组合选择,应用于雅典证券交易所
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5320
Vasileios Nastas, P. Boufounou
  Although in literature numerous multivariate models have been applied for optimal portfolio selection based on either market or accounting stock characteristics, whereby plenty of technical and/or fundamental criteria have been proposed, the problem is yet to be solved. This paper enhances a two-phased analysis that combines both fundamental and technical criteria, to overcome the aforementioned shortcomings. Initially, the fundamental characteristics of 25 stocks from 11 industries/sectors with the largest market capitalization, are compared to the performance of the Athens Stock Exchange FTSE/XA Large CAP Index, and hence two scoring tables are formed using different benchmarks, where the best performing stocks are selected. Subsequently, for these stocks, based on weekly data covering a 3-year period, the Sharpe Index Model is applied, and the best performing portfolio is selected. The estimated Sharpe Index Model (SIM) reveals that there are several opportunities to optimize return and diversify risk in an efficient manner, outperforming the FTSE Large Cap Index.   JEL Classifications: D53, G11, G12, G17, G23 Key words: Risk & Return, Technical Analysis, Fundamental Analysis, Sharpe Index Model
虽然在文献中已经应用了许多基于市场或会计股票特征的多元模型来进行最优投资组合选择,并提出了大量的技术和/或基本标准,但问题尚未得到解决。本文改进了一种结合基础标准和技术标准的两阶段分析方法,以克服上述缺点。首先,将来自11个最大市值行业/部门的25只股票的基本特征与雅典证券交易所FTSE/XA大型股票指数的表现进行比较,因此使用不同的基准形成两个计分表,其中选择表现最好的股票。随后,对于这些股票,基于3年期间的每周数据,应用夏普指数模型,选择表现最佳的投资组合。估计的夏普指数模型(SIM)显示,有几个机会以有效的方式优化回报和分散风险,表现优于富时大型股指数。JEL分类:D53, G11, G12, G17, G23关键词:风险与收益,技术分析,基本面分析,夏普指数模型

  This paper aims to contribute to the existing literature on the issue of the accounting utility not for business reasons but for non-accountants and from the point of view of everyday life financial needs and human survival. In addition, this paper aims to reveal conclusions from the application of accounting by an ordinary essentially illiterate person, including that self-taught accounting is connected to the principles of accounting and modern application experience. Applying a qualitative-determinative analysis of a handwritten bookkeeping Diary, revealed that several accepted accounting principles were applied, even instinctively, by the illiterate young person. The improvised bookkeeping suggests that basic accounting knowledge derives from the specific needs of the individual and is configured according to specific circumstances of time and place and to the ease of understanding basic accounting theory and skills. The choice to use accounting, and the sanctuary and therapeutic value of accounting as bulwark in the worst possible circumstances reveals another option of social dimension of accounting. The accounting application as a means of finding structure and guidance in an unknown world and within a tragic environment helped extremely to turn the young refugee’s disaster to a success story. The few pages from the hand-written diary of an ex WWII captive is the quite unique and interesting material this paper is constructed on and consist an undoubtable original documentation, but at the same time the scarcity of the few saved pages comprises the main research limitation. The elements considered by an “Illiterate” in the accounting field, most significant, as well as the way in which these principles were registered, should be considered in Accounting Education.   EL Classifications: D030, D100, M490 Key words: Accounting history, Bookkeeping, Accounting principles, Qualitative analysis
本文旨在为现有的关于会计效用问题的文献做出贡献,而不是出于商业原因,而是为了非会计人员,从日常生活财务需求和人类生存的角度出发。此外,本文旨在揭示一个基本不识字的普通人应用会计的结论,包括自学会计与会计原则和现代应用经验有关。通过对一份手写的记帐日记进行定性分析,发现这个不识字的年轻人甚至本能地应用了一些公认的会计原则。临时记账表明,基本的会计知识来源于个人的特定需求,并根据特定的时间和地点的情况进行配置,并且易于理解基本的会计理论和技能。使用会计的选择,以及会计作为最坏情况下堡垒的庇护和治疗价值,揭示了会计的社会维度的另一种选择。会计应用程序作为在未知世界和悲惨环境中寻找结构和指导的手段,极大地帮助将年轻难民的灾难转变为成功的故事。前二战俘虏手写日记的几页是构建本文的相当独特和有趣的材料,并且构成了无可置疑的原始文件,但同时,少数保存页面的稀缺性构成了主要的研究限制。会计领域中“文盲”所认为的最重要的因素,以及这些原则的登记方式,应在《会计教育》中加以考虑。EL分类:D030, D100, M490关键词:会计史,簿记,会计原则,定性分析

Can the commodity futures be used as effective diversifiers for pension funds investment portfolios? A literature review 商品期货能否作为养老基金投资组合的有效分散工具?文献综述

We examine from theoretical point of view whether commodity futures can produce diversification benefits for the pension funds’ investment portfolios. These asset tools have been classified in the alternative investments and as a result they are subjected to worldwide pension regulative restrictions. Reviewing the relative scientific literature of pension funds’ investment strategy and risk management, there is evidence that pension funds’ trustees might take advantage of commodity futures preference, mainly because of their a) returns’ low or negative correlation with these of other traditional options (bonds and stocks) and b) hedging positive properties against the inflation risk, resulting in the optimization of portfolios’ risk-return ratio.    JEL Classifications: G23, Q02.

本文从理论角度考察了商品期货是否能为养老基金的投资组合带来多元化收益。这些资产工具被归类为另类投资,因此它们受到全球养老金监管限制。回顾养老基金投资策略和风险管理的相关科学文献,有证据表明,养老基金的受托人可能会利用商品期货偏好,主要是因为它们的收益与其他传统期权(债券和股票)的收益低相关或负相关,以及b)对冲通胀风险的积极属性,从而优化投资组合的风险收益比。JEL分类:G23, Q02。关键词:养老基金,风险分散,另类资产,商品期货

Human Resources Management Analytics in Private Healthcare Unit 私营医疗机构人力资源管理分析
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5299

Private Greek healthcare sector consists mainly of medium and small size entities. These entities, especially small ones, rely completely on their Human Resources.  However, it seems that they do not avail themselves of new technological methods and tools for assessing their human resources. The aim of the present study was to create a methodology that will help these entities to evaluate their employees properly and to prove that the empirical knowledge of managers and heads can be enhanced by employing Data Mining methods, in order to create a successful evaluation model. In the present study, a healthcare unit consisted of 287 employees was selected. Twelve interviews were conducted with 12 managers and heads. A Graphic Rating Scale Τable, built by eight qualitative attributes, was given to the interviewees. Those 8 qualitative attributes were combined with 18 quantitative attributes in order for a new model to be created. Data were collected from the Human Resources department. To perform the analysis, Machine Learning methods were used. This model proved to be functional and capable of giving valid information to management for employees’ evaluation. Data Mining methods are quite useful for the HR department and the Administration of the unit. The above methodology provides low-costs and usable tools, for appropriate employees’ evaluation.   EL Classifications: J24, M12, M54, C38.

Project management: Lean vs. Agile methodology 项目管理:精益与敏捷方法论
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5312
Maria Georgakalou, Kostas Koutsikos
The past decades there has been a large discussion on the suitability of the lean and the agile methodologies for an effective project management. This paper aims at providing an answer to this question. Both theoretical facts and practical case studies are going to be examined in order to be able to reach a result. It seems that both methodologies might be good, depending on the problem under consideration. The two methodologies have some differences both on their starting point (LEAN was initially used in the manufacturing sector, while AGILE was initially used by the software development sector) and on their general concept (LEAN being more holistic and long-term, while AGILE is a better tool when quick decisions are needed). Aspects such as reliability of the methodologies and their challenges including reasons that might lead to failure are going to be discussed.   EL Classifications: M10 General, M11 Production Management, M19 Other Keywords: LEAN methodology, AGILE methodology, Project management, effectiveness, efficiency
在过去的几十年里,关于精益和敏捷方法对有效项目管理的适用性进行了大量的讨论。本文旨在为这个问题提供一个答案。理论事实和实际案例研究都将被检查,以便能够达到一个结果。这两种方法似乎都是好的,这取决于所考虑的问题。这两种方法在起点(LEAN最初用于制造业,而AGILE最初用于软件开发部门)和一般概念(LEAN更全面和长期,而AGILE是需要快速决策时更好的工具)上都有一些差异。将讨论诸如方法的可靠性及其挑战(包括可能导致失败的原因)等方面。EL分类:M10通用,M11生产管理,M19其他关键词:精益方法论,敏捷方法论,项目管理,有效性,效率

Branding commodity, tourist & cultural products: some thoughts on applying semiotic analysis for the marketing strategy in each product category 品牌化商品、旅游文化产品:将符号学分析应用于各品类营销策略的思考
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5318
E. Papadaki
This paper proposes the adoption of semiotic analysis to the branding process in an attempt to understand the function of the specific sign system and successfully manage its designing and evaluation processes, from audience research to audience targeting. Specific case studies of commodity, tourist and cultural product branding will be presented, in an attempt to underline, in a parallel goal, the differences and similarities of the symbolic process involved in the three areas: commodities, tourism and culture.   EL Classifications: M, Z Key words: branding, commodity products, cultural products, tourist products, semiotics
本文建议将符号学分析运用到品牌过程中,试图理解特定标识系统的功能,并成功地管理其设计和评估过程,从受众研究到受众定位。将提出商品、旅游和文化产品品牌化的具体案例研究,试图在一个平行的目标中强调商品、旅游和文化这三个领域所涉及的象征过程的异同。关键词:品牌,商品,文化产品,旅游产品,符号学

The Impact of Subjectivity on Financial Accounting 主体性对财务会计的影响
Pub Date : 2023-06-08 DOI: 10.12681/icbe-hou.5306
P. Papadeas
In this paper it is attempted to explore current trends in Financial Accounting, that connect research endeavors in the relatively new branch of Behavioral Finance, with the impact of subjectivity on the accounting cycle of each fiscal year, as well as on the preparation of financial statements. The investigation of subjective factors in Financial Accounting expands its scope, while the systematic utilization of its two-way relationship with the field of Neurofinance (unbiased data) may create a broader framework of knowledge for the further improvement of the investment process, through an understanding of the methodology required by accounting operations and rules up until the preparation of financial statements. By extension, a better understanding of how financial markets operate will be beneficial not only for governments wishing to promote savings incentives and responsible management, but also for supervisory authorities seeking to ensure that the market for personal financial services operates rationally and without bias.     Keywords: Behavioral Finance, Neurofinance, Financial Accounting JEL Classification: D87, G41, M41
在本文中,它试图探索财务会计的当前趋势,将行为金融学相对较新的分支的研究工作与主观性对每个会计年度会计周期的影响以及对财务报表编制的影响联系起来。对财务会计中主观因素的调查扩大了其范围,而系统地利用其与神经金融领域(无偏数据)的双向关系,可以通过理解会计操作和规则所需的方法,直至编制财务报表,为进一步改进投资过程创造更广泛的知识框架。推而广之,更好地理解金融市场是如何运作的,不仅有利于希望促进储蓄激励和负责任管理的政府,也有利于寻求确保个人金融服务市场合理、公正运作的监管机构。关键词:行为金融,神经金融,财务会计JEL分类:D87, G41, M41
