目的 本文评估了大同黄金与六种法定货币之间的共同走势。本文使用小波分析、BEKK-GARCH 模型和范围 DCC-GARCH 框架研究了 Pax 黄金和法定货币之间的波动溢出。此外,本文还建议使用从新的范围 DCC-GARCH 框架中获得的协方差和方差结构来估算随时间变化的最优对冲比率、最优权重和对冲效果。研究结果小波相干性方法显示,在低频下,黄金/欧元、黄金/日元和黄金/卢布货币对出现了较大的共动区。此外,BEKK 结果显示了黄金与欧元、英镑、日元和人民币(印度卢比、卢布)法定货币之间的单向(双向)传导效应。此外,Range DCC 结果显示,税金与法定货币收益之间的相关性较弱,系数较低,接近于零。因此,大同黄金似乎是抵御法定货币市场系统性风险的避风港资产。此外,最佳权重的结果表明,理性投资者应更多地投资黄金,而减少对法定货币的投资。关于对冲比率结果,研究结果显示,印度卢比(日元)法定货币似乎是对冲黄金市场最昂贵(最便宜)的对冲工具。然而,日元法币似乎是最便宜的。至于对冲有效性结果,作者发现,包括法币-大同黄金对在内的对冲策略最有可能大幅降低投资组合的风险。这项研究强调了把握这些货币之间波动性传递的重要性,为指导投资者的决策过程提供了宝贵的见解。此外,它还鼓励进一步探索数字货币之间的相互依存关系。此外,本研究还揭示了有效的传染风险管理,尤其是在 Covid-19 和俄乌冲突等危机期间。它强调了黄金作为避险资产的作用,并为在各种经济条件下调整投资组合提供了实用指导。最终,这项研究推动了我们对黄金协会风险收益状况的理解,将其定位为不确定时期的潜在对冲工具,从而为不断发展的加密货币文献做出了贡献。此外,它还通过创新性的 Range-DCC-GARCH 模型确定了最佳时变对冲比率,该模型最初由 Molnár(2016 年)引入,其与众不同之处在于同时纳入了低价和高价。值得注意的是,该分析是在 Covid-19 大流行和俄乌冲突的独特背景下展开的,标志着该领域的一项新贡献。

ESG performance and disclosure quality: does a well-balanced board of directors matter when impression management occurs? 环境、社会和公司治理绩效与信息披露质量:当出现印象管理时,均衡的董事会是否重要?
IF 5.2 Q2 BUSINESS Pub Date : 2024-03-15 DOI: 10.1108/emjb-05-2023-0140

Purpose

This paper explores how the disclosure quality, measured by the abnormal tone of environmental and social report, may determine the environmental, social and corporate governance (ESG) performance of the firm. This study also investigates the impact of the moderator “board of directors” to explore the extent to which a well-balanced board of directors may affect this association within an impression management strategy.

Design/methodology/approach

This work uses a sample of 616 firm-year observations using a sample of French firms indexed on SBF120 index from 2010 to 2017. To test the developed hypotheses, the GLS regression is applied and to control for endogeneity issue and sample selection bias, the authors used, respectively, the two stage least square (2SLS) procedure and the Heckman model.

Findings

Findings suggest that a well-balanced board of directors moderates the relationship between the ESG performance and the disclosure quality. The positive effect of abnormal tone management on ESG is weakened by the presence of a good structure of the board, attenuating impression management initiatives.

Research limitations/implications

The research provides evidence of the impact of corporate social responsibility (CSR) reporting quality, in particular disclosure tone management, on the level of ESG performance in the French context. As the board of directors may have a major impact on weakening impression management strategies in particular tone management practices, in order to improve CSR report quality, the authors recommend French companies to ensure a well-balanced board of directors.

Originality/value

This study helps investors to comprehensively evaluate the information disclosed on CSR reports. It unveils that a strong board composition induces better quality of CSR report and brings better ESG performance. Thus, the study results point to the importance of a well-balanced board of directors and the regulation of the narrative disclosure of CSR information.

目的本文探讨了以环境和社会报告的非正常基调衡量的信息披露质量如何决定企业的环境、社会和公司治理(ESG)绩效。本研究还调查了 "董事会 "这一调节因素的影响,以探讨在印象管理战略中,一个平衡的董事会可能会在多大程度上影响这种关联。为了检验提出的假设,作者采用了 GLS 回归,为了控制内生性问题和样本选择偏差,作者分别采用了两阶段最小二乘法(2SLS)程序和 Heckman 模型。研究结果研究结果表明,一个平衡的董事会可以调节 ESG 表现与信息披露质量之间的关系。研究局限性/影响研究提供了企业社会责任(CSR)报告质量,尤其是披露基调管理对法国环境、社会和公司治理绩效水平影响的证据。由于董事会可能对弱化印象管理策略,尤其是语气管理实践产生重大影响,为了提高企业社会责任报告的质量,作者建议法国公司确保董事会成员的均衡性。它揭示了强大的董事会构成会提高企业社会责任报告的质量,并带来更好的环境、社会和公司治理绩效。因此,研究结果表明了均衡的董事会和规范企业社会责任信息的叙述性披露的重要性。

Purpose

The objective of this study is to investigate the impact of the COVID-19 pandemic on the consumer payment behavior in Italy by correlating financial literacy with digital payment awareness, examining media anxiety and financial security, and including a gender analysis.

Design/methodology/approach

Consumers’ attitudes toward cashless payments were investigated using an online survey conducted from November 2021 to February 2022 on a sample of 836 Italian citizens by considering the behavioral characteristics and aspects of financial literacy. Structural equation modeling (SEM) was used to test the hypotheses and to determine whether the model was invariant by gender.

Findings

The analysis showed that the fear of contracting COVID-19 and the level of financial literacy had a direct influence on the payment behavior of Italians, which was completely different in its weighting. Fear due to the spread of news regarding the pandemic in the media indirectly influenced consumers’ noncash attitude. The preliminary results of the gender multigroup analysis showed that cashless payment was the same in the male and female subpopulations.

Originality/value

This research is noteworthy because of its interconnected examination. It examined the effects of the COVID-19 pandemic on people’s payment choices, assessed their knowledge, and considered the influence of media-induced anxiety. By combining these factors, the study offered an analysis from a gender perspective, providing understanding of how financial behaviors were shaped during the pandemic.

目的本研究旨在通过将金融知识与数字支付意识相关联、研究媒体焦虑和金融安全以及性别分析,调查 COVID-19 大流行对意大利消费者支付行为的影响。设计/方法/途径在 2021 年 11 月至 2022 年 2 月期间对 836 名意大利公民进行了在线调查,通过考虑行为特征和金融知识的各个方面,调查了消费者对无现金支付的态度。分析结果表明,对感染 COVID-19 的恐惧和金融知识水平对意大利人的支付行为有直接影响,两者的权重完全不同。由于媒体传播有关该流行病的消息而产生的恐惧间接影响了消费者的非现金态度。性别多组分析的初步结果显示,非现金支付在男性和女性亚群中是相同的。它研究了 COVID-19 大流行对人们支付选择的影响,评估了他们的知识,并考虑了媒体引发的焦虑的影响。通过将这些因素结合在一起,该研究从性别角度进行了分析,从而让人们了解在大流行病期间金融行为是如何形成的。

Purpose

The purpose of this study is to examine various key aspects associated with entrepreneurs’ behaviour following a long-term crisis. Specifically, the study compares the perceptions of female and male entrepreneurs operating in Cyprus and Greece concerning success factors and firm performance in the aftermath of the global financial crisis. Conceptually, the study considers the organisational adaptation literature (Miles and Snow’s typology).

Design/methodology/approach

The views of female and male micro and small firm owners-managers operating in Greece and Cyprus, a total of 406, were gathered through a questionnaire. To analyse the quantitative data, independent samples t-test and exploratory factor analysis were applied.

Findings

Participants’ responses reveal similar levels of perceived importance between genders regarding adaptive measures and strategies to confront a long-term crisis, as well as perceived firm performance. Nevertheless, exploratory factor analysis highlights differences in how male/female entrepreneurs perceive actions that, as in the case of financial management, can safeguard the immediate outlook of the firm.

Originality/value

While scholarly discourses on gender and entrepreneurship abound, important knowledge gaps still exist, for instance, in entrepreneurs’ problem-solving strategies adopted by female and male entrepreneurs following crises. In addressing this scholarly gap cross-culturally, that is, drawing on cross-national data (Cyprus and Greece); the present study makes an important contribution. Empirically, the study ascertains similar entrepreneurial behavioural characteristics between female-male entrepreneurs. Theoretically, the study validates Miles and Snow’s typology and develops a theoretical framework linking the typology and dimensions emerging from the empirical findings.

目的 本研究旨在探讨长期危机后与企业家行为相关的各个关键方面。具体而言,本研究比较了在塞浦路斯和希腊经营的女性和男性企业家对全球金融危机后成功因素和公司业绩的看法。在概念上,本研究考虑了组织适应性文献(迈尔斯和斯诺的类型学)。设计/方法/途径通过问卷调查收集了在希腊和塞浦路斯经营的男女微型和小型公司所有者-管理者(共 406 人)的观点。分析定量数据时,采用了独立样本 t 检验和探索性因素分析。研究结果参与者的回答显示,在应对长期危机的适应性措施和战略方面,两性对其重要性的认识程度以及对公司业绩的认识程度相似。尽管有关性别和创业的学术论述比比皆是,但仍存在着重要的知识差距,例如女性和男性创业者在危机发生后所采取的解决问题的策略。本研究利用跨国数据(塞浦路斯和希腊),跨文化地解决了这一学术空白,做出了重要贡献。从经验上讲,本研究确定了女性和男性创业者之间相似的创业行为特征。从理论上讲,本研究验证了迈尔斯和斯诺的类型学,并建立了一个理论框架,将类型学与实证研究结果中出现的维度联系起来。

The financial performance of Lebanese banks up to the financial crisis: do audit committee characteristics and ownership concentration matter? 金融危机前黎巴嫩银行的财务业绩:审计委员会的特点和所有权集中度是否重要?
IF 5.2 Q2 BUSINESS Pub Date : 2024-03-08 DOI: 10.1108/emjb-07-2023-0199
Rasha Mohammad Nouraldeen

Purpose

The focus on corporate governance has increased after the financial collapses of several banks worldwide, such as Silicon Valley Bank and First Republic Bank in the USA, and the failure of the Lebanese banking sector. This study examines the impact of audit committee (AC) characteristics on financial performance and investigates the moderating effect of ownership concentration (OC) on the associations between AC characteristics and profitability.

Design/methodology/approach

The current research is carried out based on 211 Lebanese banks’ annual reports, focusing on the period from 2012 to 2021. The ordinal least squares (OLS) and the hierarchical multiple regression analysis were adopted to test the study’s hypotheses.

Findings

The outcomes reveal that AC size, AC frequency of meetings, and banks’ size (control variable) positively affect financial performance; however, OC does not moderate the associations between the AC characteristics and banks’ profitability.

Originality/value

According to the researcher’s knowledge, no prior study has investigated the moderating effect of OC on these associations. Moreover, the current study contributes to the literature that documented mixed and inconsistent results regarding the direct associations between AC characteristics and financial performance.

目的 在全球几家银行(如美国硅谷银行和第一共和银行)发生财务崩盘以及黎巴嫩银行业倒闭之后,对公司治理的关注与日俱增。本研究探讨了审计委员会(AC)特征对财务业绩的影响,并研究了所有权集中度(OC)对审计委员会特征与盈利能力之间关系的调节作用。研究结果表明,AC 规模、AC 会议频率和银行规模(控制变量)对财务业绩有积极影响;然而,OC 并不能调节 AC 特征与银行盈利能力之间的关联。此外,有关 AC 特征与财务绩效之间直接关联的文献记载结果不一,且存在矛盾,本研究为这些文献做出了贡献。

Cash flow management, performance and risk: evidence from Greece 现金流管理、绩效和风险:来自希腊的证据
IF 5.2 Q2 BUSINESS Pub Date : 2024-02-29 DOI: 10.1108/emjb-09-2023-0245
Gerasimos Rompotis

Purpose

I seek to identify whether cash flow management can affect the performance and risk of the Greek listed companies.

Design/methodology/approach

This study examines the relationship of cash flow management with performance and risk, using a sample of 80 non-financial companies listed in the Athens Exchange. The study covers the period 2018–2022, and panel data analysis is applied. Both financial performance and stock return are taken into consideration, while risk concerns the volatility of the companies’ share prices. The various explanatory variables used include the net cash flow, free cash flow, cash conversion cycle days, cash flow from operating activities, cash flow from investing activities, cash flow from financing activities, inventory days, customer days and supplier days.

Findings

The empirical results provide evidence of a positive relationship between financial performance and net cash flow and free cash flow. In addition, operating cash flow is positively related to financial performance. The opposite is the case for investing and financing cash flow. Finally, some evidence of a negative relationship between financial performance and inventory and customer days is provided too. On the other hand, stock return and risk are not related to the cash flow management variables at all.

Originality/value

To the best of my knowledge, this is one of the few studies to examine the relationship of cash flow management with performance and risk, using data from the Greek stock market. The results can form an effective selection tool for investors seeking Greek companies with the highest financial performance potential, which may reward them with higher dividends.

目的我试图确定现金流管理是否会影响希腊上市公司的业绩和风险。设计/方法/途径本研究以雅典交易所上市的 80 家非金融公司为样本,考察现金流管理与业绩和风险之间的关系。研究时间跨度为 2018-2022 年,采用面板数据分析。财务业绩和股票回报都被考虑在内,而风险则涉及公司股价的波动性。使用的各种解释变量包括净现金流、自由现金流、现金转换周期天数、经营活动现金流、投资活动现金流、融资活动现金流、存货天数、客户天数和供应商天数。此外,经营现金流与财务业绩呈正相关。投资和融资现金流的情况则相反。最后,还有一些证据表明财务业绩与库存和客户工作日之间存在负相关关系。原创性/价值 据我所知,这是为数不多的利用希腊股市数据研究现金流管理与业绩和风险关系的研究之一。研究结果可为投资者提供有效的选择工具,帮助他们寻找财务业绩潜力最大的希腊公司,从而获得更高的股息回报。

Purpose

This paper aims to map the evolution of hydrogen-based technologies (HBTs) by examining the patenting activity associated to these technlogies from 1930 to 2020. In doing so, the study provides a novel perspective on the development of HBTs and offers implications for managers and policymakers.

Design/methodology/approach

We collected patent data at the level of patent families (PFs). Our sample includes 317,089 PFs related to hydrogen production and 62,496 PFs to hydrogen storage. We examined PF data to delineate the state of the art and major technical advancements of HBTs.

Findings

Our analysis provides evidence of an increasing patenting activity in the area of HBTs, hence suggesting relatively high levels of expectations on the economic potential of these technologies. US and Japan hold the largest proportion of PFs related to HBTs (about 60%), while European applicants hold the highest proportion of highly cited PFs (about 60%). While firms represent the applicant with the highest share of PFs, our analysis reveals that firms holding HBT PFs are primarily from the chemical sector.

Research limitations/implications

While our analysis is limited to examining patent data which capture some aspects of the innovation activity around HBTs (namelly, patented inventions), our study enriches existing literature by performinng a patent analysis on a much larger sample of data when compared to previous studies.

Practical implications

Two main implications emerge from our study. Firstly, there seems to be an urgent need to support the emergence of a dominant design so as to facilitate the consolidation and diffusion of the HBTs, hence the transition to a more sustainable energy production. Secondly, the majority of HBT PFs are held by a small number of countries. This, in turn, suggests opportunities to develop cross-country cooperation (e.g. international agreements, research and technology offices) to support the development and adoption of HBTs globally.

Social implications

Considering the results obtained in this study, from a social point of view, the attention that organizations have paid to hydrogen related technologies is evident. This suggests that the development HBTs can function as a social enabler for a sustianable energy transition.

Originality/value

Extant research has focused on the individual components of the hydrogen chain. As a result, we lack a comprehensive understanding of the progress made in the area of HBTs. To address this gap, this study examined HBTs by focusing on both production and storage technologies since their initial developments, hence adopting an observation period of about 70 years.

目的 本文旨在通过研究1930年至2020年与氢基技术(HBT)相关的专利活动,描绘氢基技术的发展历程。我们收集了专利族(PFs)层面的专利数据。我们的样本包括与制氢相关的 317,089 项专利族和与储氢相关的 62,496 项专利族。我们对专利族数据进行了研究,以了解 HBT 的技术发展状况和主要技术进步。研究结果我们的分析表明,HBT 领域的专利申请活动不断增加,这表明人们对这些技术的经济潜力抱有较高的期望。美国和日本持有的与 HBT 相关的专利申请所占比例最大(约 60%),而欧洲申请人持有的高引用率专利申请所占比例最高(约 60%)。我们的分析表明,持有 HBT PFs 的公司主要来自化学领域。研究局限/意义虽然我们的分析仅限于研究专利数据,而这些数据捕捉到了围绕 HBT 的创新活动的某些方面(即专利发明),但与以往的研究相比,我们的研究对更大的数据样本进行了专利分析,从而丰富了现有文献。首先,似乎急需支持主导设计的出现,以促进 HBT 的巩固和推广,从而向更可持续的能源生产过渡。其次,大多数 HBT PF 由少数国家持有。社会影响考虑到本研究的结果,从社会角度来看,各组织对氢相关技术的关注是显而易见的。原创性/价值目前的研究主要集中在氢产业链的各个环节。因此,我们对氢化热电联产领域所取得的进展缺乏全面的了解。为了弥补这一不足,本研究从氢化镱最初开发以来的生产和储存技术入手,对氢化镱进行了研究,因此采用了约 70 年的观察期。

Purpose

This paper explores the connection between capital structure and financial performance within European listed firms. The primary objective is to demonstrate an inverse U-shaped relationship between these two variables and pinpoint an optimal debt-equity mix.

Design/methodology/approach

In this study, we adopt a dynamic modeling approach to investigate the relationship between a firm’s capital structure and financial performance. Drawing on well-established theories and prior empirical studies, our model examines 3,121 dividend-paying firms from 41 European countries over 14 years, from 2008 to 2021. To enhance the reliability of our findings, we employ two distinct estimation techniques: the fixed effect model (FE) and the system generalized method of moments (System-GMM).

Findings

This study reveals an inverse U-shaped relationship between the firm’s financial performance, measured by the return on equity (ROE) and its capital structure (total liability to total assets ratio). Furthermore, an optimal capital structure of about 29% is determined for all firms in the sample, and about 21%, 28% and 41% industry-specific capital structure for manufacturing, real estate and wholesale trade, respectively.

Originality/value

This paper contributes to existing knowledge by empirically determining an optimal capital structure for listed firms across various industries in Europe, which very few studies have attempted to do in the past. An optimal capital structure is an invaluable benchmark for managers and other stakeholders, informing their decision-making.

目的 本文探讨了欧洲上市公司的资本结构与财务业绩之间的关系。主要目的是证明这两个变量之间存在反 U 型关系,并确定最佳的债务-股权组合。 设计/方法/途径 在本研究中,我们采用动态建模方法来研究公司资本结构与财务业绩之间的关系。我们的模型借鉴了成熟的理论和先前的实证研究,对 41 个欧洲国家的 3121 家分红企业进行了 14 年的研究,时间跨度从 2008 年到 2021 年。为了提高研究结果的可靠性,我们采用了两种不同的估算技术:固定效应模型(FE)和系统广义矩法(System-GMM)。 研究结果 本研究揭示了以股本回报率(ROE)衡量的公司财务绩效与其资本结构(总负债与总资产比率)之间的反 U 型关系。此外,所有样本公司的最优资本结构约为 29%,而制造业、房地产和批发贸易行业的最优资本结构分别约为 21%、28% 和 41%。最佳资本结构是管理者和其他利益相关者的宝贵基准,可为他们的决策提供参考。
