We examine the U-shaped effect of technological progress on CO₂ emissions using digital and high-tech trade as well as R&D levels as threshold variables. By analyzing a comprehensive European Union dataset, we reveal the U-shaped effects of digital and high-tech trade and R&D investment on CO₂ emissions, suggesting that technological progress modifies the conventional Environmental Kuznets Curve. At low levels of technological progress, it reduces CO₂ emissions; however, CO₂ emissions increase again beyond a certain threshold. Institutional quality moderates this relationship, highlighting its role in shaping the environmental impact of technological progress, and mitigates the negative impact of technological progress on emissions in its advanced stages. As investors become more aware of environmental liabilities and regulations, incorporating environmental factors into financial policies and risk management becomes crucial. Our findings underscore the role of institutional quality in mitigating the adverse effects of technological progress on CO₂ emissions.
我们使用数字和高科技贸易以及研发水平作为阈值变量来检验技术进步对二氧化碳排放的u型影响。通过分析一个全面的欧盟数据集,我们揭示了数字和高科技贸易以及研发投资对二氧化碳排放的u型影响,这表明技术进步改变了传统的环境库兹涅茨曲线。在技术进步水平较低的情况下,它减少了二氧化碳的排放;但是,超过一定阈值后,二氧化碳排放量会再次增加。制度质量调节了这种关系,突出了其在形成技术进步的环境影响方面的作用,并减轻了技术进步在其后期阶段对排放的负面影响。随着投资者越来越意识到环境责任和法规,将环境因素纳入金融政策和风险管理变得至关重要。我们的研究结果强调了制度质量在减轻技术进步对二氧化碳排放的不利影响方面的作用。

We investigate the impact of vertical mergers on bank loans of acquirers' and targets' rivals. Following a vertical merger, these rivals experience higher interest rate spreads on bank loans, shorter loan maturities, and more stringent contract covenants. We observe the increase in the cost of debt whether or not the merger is part of an industry merger wave, mitigating concerns that unobserved industry factors drive our findings. While vertical mergers can foreclose markets for rivals, they can also create efficiencies for the merging firms by reducing the holdup problem in relationship-specific investments. Utilizing asset specificity measures to assess the severity of the holdup problem, we find that rivals' cost of debt increases when vertical mergers are more likely motivated by foreclosure rather than efficiency motives.
我们研究了垂直并购对收购方和目标方竞争对手银行贷款的影响。垂直合并后,这些竞争对手的银行贷款利差更高,贷款期限更短,合同条款更严格。我们观察到,无论合并是否是行业合并浪潮的一部分,债务成本都会增加,这减轻了人们对未观察到的行业因素推动我们研究结果的担忧。虽然垂直合并可以阻止竞争对手进入市场,但它们也可以通过减少特定关系投资中的拖延问题,为合并公司创造效率。利用资产专用性措施来评估持股问题的严重程度,我们发现,当垂直合并更有可能是由止赎而非效率动机驱动时,竞争对手的债务成本会增加。

While recent studies have explored how firms react to credit rating events, the specific impact of news disclosed in credit rating change announcements on dividend policy remains largely unexplored. We analyze a sample of dividend paying firms that consistently paid dividends from 1995 to 2019 to examine whether, and to what extent, firms adjust dividend policy in credit rating shocks. Focusing on the type of information conveyed to the capital markets, we identify three types of downgrades, namely, “bad”, “good”, and “systemic” and upgrades associated with strong financial performance. We provide evidence that firms smooth dividends more under a “good” downgrade and less under a “bad” downgrade, a “systemic” downgrade and an upgrade. In favor of this finding, we show that dividend forecast errors are positively associated with “bad” downgrades, “systemic” downgrades and upgrades, but are not associated with “good” downgrades.
虽然最近的研究已经探讨了公司对信用评级事件的反应,但信用评级变化公告中披露的新闻对股息政策的具体影响在很大程度上仍未被探讨。我们分析了1995年至2019年持续支付股息的公司样本,以检验公司在信用评级冲击中是否以及在多大程度上调整了股息政策。关注传递给资本市场的信息类型,我们确定了三种类型的降级,即“坏”、“好”和“系统性”,以及与强劲财务业绩相关的升级。我们提供的证据表明,公司在“好”评级下调时更容易平滑股息,而在“坏”评级下调、“系统性”评级下调和评级上调时则更少。为了支持这一发现,我们表明股息预测误差与“坏”降级、“系统性”降级和升级呈正相关,但与“好”降级无关。

We investigate whether adopting a uniform set of accounting standards impacts stock price efficiency by introducing a novel empirical test imported from the finance literature. Using mandatory adoption of International Financial Reporting Standards (IFRS) as an exogenous shock to the accounting information disclosure environment and employing a difference-in-difference research design, we find that the extent to which stock prices deviate from their fundamental values decreases significantly following the adoption of IFRS. In cross-sectional tests, we further observe that the impact of IFRS adoption on stock price efficiency is more pronounced in countries with lower accounting quality prior to IFRS adoption and in those with substantial differences between their domestic Generally Accepted Accounting Principles (GAAP) and IFRS. Overall, our study contributes to the literature by empirically examining a fundamental aspect of the IFRS mission statement—whether IFRS adoption enhances financial market efficiency.
我们通过引入一个从金融文献中引进的新的实证检验来研究采用统一的会计准则是否会影响股价效率。采用强制性采用国际财务报告准则(IFRS)作为会计信息披露环境的外生冲击,并采用差异中差异研究设计,我们发现,在采用国际财务报告准则后,股价偏离其基本价值的程度显着降低。在横断面测试中,我们进一步观察到,在采用国际财务报告准则之前会计质量较低的国家,以及在其国内公认会计原则(GAAP)与国际财务报告准则之间存在重大差异的国家,采用国际财务报告准则对股价效率的影响更为明显。总体而言,我们的研究通过实证检验国际财务报告准则使命声明的一个基本方面——采用国际财务报告准则是否提高了金融市场效率——对文献做出了贡献。

The efficiency of financial systems in fostering economic growth remains a critical concern, particularly in Sub-Saharan Africa, where financial markets and institutions exhibit structural weaknesses. Existing literature predominantly focuses on the dichotomy between bank-based and market-based financial systems, overlooking the relative contributions of different financial institutions. Using data from 22 Sub-Saharan African countries from 2006 to 2017, we examine the role of banks, stock markets, microfinance, credit unions and credit cooperatives, other deposit takers, and non-resident banks in enhancing economic efficiency. Employing the generalized method of moments, we find that deposit-taking institutions exert the most substantial impact, while investments in stock markets are twice as effective as bank loans in driving economic performance. Additionally, our results indicate that banking activities complement both stock markets and deposit-taking institutions, but we observe no significant relationship between stock markets and deposit takers. These findings challenge the conventional wisdom that distinguishes between market-based and bank-based financial systems as primary factors for economic growth. Instead, we argue that the composition and interaction of institutions within the financial system are more critical for fostering economic efficiency. This study provides valuable implications for policymakers and financial practitioners, emphasizing the need to focus on institutional dynamics rather than merely the structural type of financial system. By enhancing our understanding of these relationships, our findings contribute to the broader debate of financial development and economic performance in emerging markets.
金融系统在促进经济增长方面的效率仍然是一个重大问题,特别是在撒哈拉以南非洲,那里的金融市场和机构表现出结构性弱点。现有文献主要关注以银行为基础的金融体系和以市场为基础的金融体系之间的二分法,忽视了不同金融机构的相对贡献。利用2006年至2017年22个撒哈拉以南非洲国家的数据,我们研究了银行、股票市场、小额信贷、信用合作社和信用合作社、其他存款机构以及非居民银行在提高经济效率方面的作用。采用广义矩法,我们发现存款机构发挥了最实质性的影响,而股票市场投资在推动经济表现方面的效果是银行贷款的两倍。此外,我们的研究结果表明,银行活动对股票市场和存款机构都是互补的,但我们观察到股票市场和存款机构之间没有显著的关系。这些发现挑战了将市场金融体系与银行金融体系区分为经济增长主要因素的传统观念。相反,我们认为金融体系内机构的构成和相互作用对于促进经济效率更为重要。这项研究为政策制定者和金融从业者提供了有价值的启示,强调需要关注制度动态,而不仅仅是金融体系的结构类型。通过加强我们对这些关系的理解,我们的发现有助于对新兴市场金融发展和经济表现的更广泛讨论。

In light of the rising macro-financial, geopolitical, and environmental risks, alternative assets such as cryptocurrencies, green bonds, and sukuk have received increasing attention for their potential in risk hedging and diversification. This study examines the dynamic return spillovers and risk-sharing interconnections among conventional and gold-backed Islamic cryptocurrencies, green bonds, and sukuk using daily data from 2018 to 2023. Employing a novel combination of frequency-based quantile connectedness and quantile cross-spectral techniques, we investigate time- and frequency-dependent interconnections under varying market conditions. Our results are threefold: First, Islamic gold-backed cryptocurrencies, green bonds, and sukuk exhibit intense co-movement and risk-sharing, in contrast to conventional cryptocurrencies, which display differential patterns. Second, return spillovers and connectedness intensify significantly during market stress periods such as the COVID-19 pandemic and the Russia–Ukraine war, with Islamic gold-backed cryptocurrencies showing stronger resilience and hedging potential than conventional cryptocurrencies. Third, return spillovers are more pronounced in the short term compared to the long term, potentially driven by liquidity flows, investor behavior, and high-frequency trading. Our findings suggest important implications for investors, fund managers, regulators, and policymakers.
鉴于宏观金融、地缘政治和环境风险的不断上升,加密货币、绿色债券和伊斯兰债券等另类资产因其在风险对冲和多样化方面的潜力而受到越来越多的关注。本研究利用2018年至2023年的日常数据,研究了传统和黄金支持的伊斯兰加密货币、绿色债券和伊斯兰债券之间的动态回报溢出效应和风险分担相互关系。采用基于频率的分位数连通性和分位数交叉频谱技术的新组合,我们研究了不同市场条件下的时间和频率相关的互连。我们的研究结果有三个方面:首先,与传统加密货币表现出差异模式相比,伊斯兰黄金支持的加密货币、绿色债券和伊斯兰债券表现出强烈的协同运动和风险分担。其次,在2019冠状病毒病大流行和俄乌战争等市场压力时期,回报溢出效应和连通性显著加剧,伊斯兰黄金支持的加密货币比传统加密货币表现出更强的弹性和对冲潜力。第三,回报溢出效应在短期内比长期更为明显,这可能是由流动性流动、投资者行为和高频交易驱动的。我们的研究结果对投资者、基金经理、监管机构和政策制定者具有重要意义。

Motivated by the pioneering work of Porter (1990) and a vast supporting literature, we posit that global competitiveness improves a nation's ability to benefit from globalization and financial liberalization. To prove the veracity of this supposition, we study the relationship between the competitiveness of countries worldwide, as measured by the Global Competitiveness Index as well as its sub-indices, and the market liquidity of cross-listed stocks from 43 countries on the NYSE between 2006 and 2019. Our findings suggest that a country's greater global competitiveness extends beyond its borders, thereby significantly enhancing the liquidity of its foreign-listed stocks. This extenuating impact of global competitiveness on cross-listed stocks is partially but significantly due to reduced information asymmetry in global markets. Competitiveness associated with efficiency and innovation are particularly crucial in improving market liquidity and ameliorating the adverse effects of information asymmetry on market liquidity.
在波特(1990)的开创性工作和大量支持文献的激励下,我们假设全球竞争力提高了一个国家从全球化和金融自由化中受益的能力。为了证明这一假设的真实性,我们研究了2006年至2019年间全球各国竞争力(以全球竞争力指数及其子指数衡量)与纽约证券交易所43个国家交叉上市股票的市场流动性之间的关系。我们的研究结果表明,一个国家更大的全球竞争力延伸到其国界之外,从而显著提高其海外上市股票的流动性。全球竞争力对交叉上市股票的减轻影响部分但显著地是由于全球市场信息不对称的减少。与效率和创新相关的竞争力在提高市场流动性和改善信息不对称对市场流动性的不利影响方面尤为重要。

This paper studies a theoretical question: Why is cryptocurrency so volatile? To investigate this, I apply a New Monetary model that incorporates an adaptive learning assumption. Specifically, building on the baseline framework of Choi and Rocheteau (2021), I relax their perfect foresight assumption by replacing it with adaptive learning. I show how high volatility can emerge under this revised assumption. With a simple learning rate algorithm, I find that adaptive learning can alter the stability of steady states. For instance, with a high learning rate, the system can experience a period of doubling bifurcation, potentially leading to chaotic regimes or explosive paths. These price dynamics help explain the extreme volatility observed in cryptocurrency markets.
本文研究了一个理论问题:为什么加密货币如此不稳定?为了研究这个问题,我采用了一个包含适应性学习假设的新货币模型。具体来说,在Choi和Rocheteau(2021)的基线框架的基础上,我用适应性学习取代了他们的完美预见假设,从而放松了他们的假设。我展示了在这个修正的假设下,高波动性是如何出现的。通过一个简单的学习率算法,我发现自适应学习可以改变稳态的稳定性。例如,在高学习率的情况下,系统可能会经历一段双倍分叉的时期,这可能会导致混乱的状态或爆炸性的路径。这些价格动态有助于解释加密货币市场的极端波动。

These price dynamics help explain the extreme volatility observed in cryptocurrency markets.</div></div>","PeriodicalId":46907,"journal":{"name":"Global Finance Journal","volume":"67 ","pages":"Article 101132"},"PeriodicalIF":5.5,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144366703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze the impact of terrorism on cross-border mergers and acquisitions (M&As) and find that terrorist attacks in acquirer and target countries significantly influence both the initiation and completion of M&As. While the presence of terrorism deters deal initiation, it paradoxically increases the likelihood of deal completion, suggesting a complex interplay of risk assessment and strategic decision-making. Furthermore, we find that firms accelerate completion after terrorist attacks.
我们分析了恐怖主义对跨国并购的影响,发现并购方和目标国的恐怖袭击对并购的发起和完成都有显著影响。虽然恐怖主义的存在阻碍了交易的启动,但矛盾的是,它增加了交易完成的可能性,表明风险评估和战略决策之间存在复杂的相互作用。此外,我们发现企业在恐怖袭击后加速完工。

This study investigates how governance characteristics, specifically gender diversity, and bank business models influence the transition from greenwashing and greenhushing to becoming green banks. A balanced panel of 150 listed banks worldwide from 2015 to 2021 is used. Latent Markov models are applied as a methodology capable of explaining the evolution of a group of banks and the characteristics that may affect their transition over time. Key findings reveal a positive correlation between having a female CEO with at least 30 % female board representation and the likelihood of a bank shifting from greenwashing to a green stance. Conversely, a higher proportion of women on the board appears to reduce the likelihood of transitioning from greenhushing to a vocal green position, suggesting a more risk-averse and conservative approach. Additionally, investment-oriented banks are more likely to evolve toward vocal green banking than retail and universal banks. The research advances the literature on greenwashing and greenhushing by highlighting the importance of governance characteristics in supporting environmentally responsible practices.
本研究探讨了治理特征(特别是性别多样性)和银行业务模式如何影响从“洗绿”和“粉饰绿色”向“绿色银行”的转变。我们使用了2015年至2021年全球150家上市银行的均衡面板。潜在马尔可夫模型是一种能够解释一组银行的演变以及可能影响其随时间过渡的特征的方法。主要调查结果显示,女性CEO在董事会中至少占30%的比例,与银行从“洗绿”转向“绿色”立场的可能性呈正相关。相反,女性在董事会中所占比例较高,似乎降低了从“绿色外壳”转变为直言不讳的绿色立场的可能性,这表明一种更倾向于规避风险和保守的做法。此外,投资导向型银行比零售银行和全能银行更有可能向绿色银行发展。该研究通过强调治理特征在支持环境负责任实践中的重要性,推进了关于绿色清洗和绿色掩饰的文献。
