This study examines how kinship and social ties between CEOs and board members affect firm value. Surname sharing is leveraged as a proxy for kinship ties within the unique Confucian context of Korea. Utilizing a dataset of publicly listed Korean firms from 2011 to 2022, this study finds that CEO-board surname sharing has a negative relationship with firm value. This adverse effect is more pronounced when CEO power is higher. Stronger kinship ties appear to harm firm value through four channels: 1) Investment inefficiency, 2) Compensation inefficiency, 3) Reduced reporting quality, and 4) Deteriorated operating performance. These kinship ties are strengthened when offline meetings between clan associations take place. Moreover, boards comprising older members primarily drive the negative relationship with firm value, implying that time attenuates traditional Confucian kinship norms. By demonstrating how culturally embedded kinship and social ties influence firm value, the findings contribute to the literature on CEO-board dynamics and corporate governance.
本研究考察了ceo和董事会成员之间的亲属关系和社会关系如何影响公司价值。在韩国独特的儒家背景下,姓氏共享被用作亲属关系的代表。利用2011年至2022年韩国上市公司的数据集,本研究发现ceo -董事会姓氏共享与公司价值呈负相关。CEO权力越大,这种负面影响就越明显。亲属关系增强对企业价值的损害表现为投资效率低下、薪酬效率低下、报告质量下降和经营绩效恶化。这些亲属关系在氏族协会举行线下会议时得到加强。此外,由年长成员组成的董事会主要推动了与公司价值的负相关关系,这意味着时间削弱了传统的儒家亲属规范。通过展示文化嵌入的亲属关系和社会关系如何影响公司价值,研究结果有助于ceo -董事会动态和公司治理的文献。

This study examines whether machine learning (ML) techniques can improve the prediction of insider trading behaviour compared with traditional linear approaches. Using a comprehensive sample of U.S. insider trading data from 2000 to 2022, we compare ensemble learning methods—random forest and extreme gradient boosting—to logistic regression and least absolute shrinkage and selection operator (LASSO). We implement Bayesian hyperparameter optimisation to improve model tuning and employ Shapley additive explanations (SHAP) values to maintain interpretability and identify the principal economic determinants of insider trading decisions. Additionally, we apply Gaussian Thompson sampling to evaluate competing hypotheses about insiders' market-timing motives. The results demonstrate that ML methods substantially outperform linear models in predicting both the likelihood and magnitude of insider sales, with predictive gains particularly pronounced among female insiders. SHAP analysis indicates that incentive structures play a stronger role for male insiders, whereas female trading behaviour appears more closely associated with private information about future firm performance.
本研究考察了与传统线性方法相比,机器学习(ML)技术是否可以改善对内幕交易行为的预测。使用2000年至2022年美国内幕交易数据的综合样本,我们比较了集成学习方法-随机森林和极端梯度增强-与逻辑回归和最小绝对收缩和选择算子(LASSO)。我们实施贝叶斯超参数优化来改进模型调整,并采用Shapley加性解释(SHAP)值来保持可解释性并确定内幕交易决策的主要经济决定因素。此外,我们应用高斯汤普森抽样来评估关于内幕人择时动机的竞争假设。结果表明,机器学习方法在预测内部销售的可能性和规模方面大大优于线性模型,在女性内部人员中预测收益尤其明显。SHAP分析表明,激励结构对男性内部人的作用更大,而女性的交易行为似乎与公司未来业绩的私人信息更密切相关。

Information concealment effects or signaling effect of industrial policy: Evidence from stock price crash risk 产业政策的信息隐藏效应或信号效应:来自股价崩盘风险的证据
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2026-01-03 DOI: 10.1016/j.gfj.2026.101234

Industrial policies generate both positive and negative information effects. Existing research largely emphasizes their signaling benefits while overlooking potential adverse impacts. Using the High-Tech Enterprise Identification Policy (HTEP) as a quasi-natural experiment, this study applies a staggered difference-in-differences model to examine how industrial policy influences stock price crash risk. The findings reveal that HTEP produces an information concealment effect that heightens crash risk. This effect is most pronounced among nonstate-owned and pseudo high-tech enterprises, where controlling shareholders conceal negative information for tax arbitrage and equity transfer, further increasing risk. Channel analysis indicates that HTEP intensifies information asymmetry among external investors, amplifying market instability. Grounded in Type II agency theory, the study identifies research and development information manipulation as a new mechanism linking industrial policy to crash risk, thereby expanding the theoretical framework of stock price dynamics. These results provide empirical evidence on the information effects of industrial policy and offer policy insights to improve the design and execution of innovation-driven industrial strategies worldwide.
产业政策产生正面和负面的信息效应。现有的研究大多强调了它们的信号作用,而忽视了潜在的不利影响。本研究以高新技术企业认定政策(HTEP)为准自然实验,运用交错差中差模型考察产业政策对股价崩盘风险的影响。研究结果表明,HTEP产生了信息隐藏效应,增加了撞车风险。这种影响在非国有企业和伪高新技术企业中最为明显,控股股东隐瞒负面信息进行税收套利和股权转让,进一步增加了风险。渠道分析表明,HTEP加剧了外部投资者之间的信息不对称,放大了市场的不稳定性。本研究以第二类代理理论为基础,将研发信息操纵作为产业政策与崩溃风险联系的新机制,拓展了股价动态的理论框架。这些结果为产业政策的信息效应提供了实证证据,并为改善全球创新驱动产业战略的设计和执行提供了政策见解。

From corporate responsibility to corporate sustainability: A study of how ESG mitigates corporate default risk using serial mediation analysis 从企业责任到企业可持续性:ESG如何缓解企业违约风险的序列中介分析
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2025-11-26 DOI: 10.1016/j.gfj.2025.101225

This study investigates how Environmental, Social, and Governance (ESG) performance is linked to the corporate default risk. Using listed Indian firms from 2016 to 2024, this study finds that ESG performance and its individual dimensions are negatively related to default risk via improved Altman Z-score. The advanced serial mediation analysis using the PROCESS model 6 suggests that ESG information is transmitted to lower default risk via enhanced corporate efficiency (CEF), improved financial performance indicated by return on assets (ROA), and lowered the cost of borrowing indicated by the cost of debt (COD). Applying the Propensity Score Matching (PSM) and Difference-in-Difference (DID) technique, this study also documents that firms that are part of the NIFTY100ESG index have significantly better financial resilience than companies not part of the index after the COVID-19 crisis. Through ex-post analysis in the case of defaulted firms, this study finds that ESG performance can predict corporate default events if combined with other parameters effectively. The findings supported by the legitimacy theory indicate that firms can increase corporate sustainability and legitimacy not only through improvements in corporate efficiency and profitability but also through external perceptions, responsibility, and ethical practices, which function as an ‘insurance effect’. Thus, policymakers should encourage lenders to integrate ESG factors into business models and promote sustainable business practices to reduce financial risks. This will accelerate the firms' adoption of cleaner technologies, enhance governance standards, and strengthen overall financial stability and corporate sustainability.
本研究探讨了环境、社会和治理(ESG)绩效与企业违约风险之间的关系。本文以2016 - 2024年的印度上市公司为研究对象,通过提高Altman Z-score,发现ESG绩效及其个体维度与违约风险呈负相关。使用PROCESS模型6的高级序列中介分析表明,ESG信息通过提高企业效率(CEF)、改善资产收益率(ROA)和降低债务成本(COD)来传递,从而降低违约风险。运用倾向得分匹配(PSM)和差分法(DID)技术,本研究还证明,在2019冠状病毒病危机后,纳入NIFTY100ESG指数的公司的财务弹性明显优于未纳入该指数的公司。通过对违约企业的事后分析,本研究发现,如果与其他参数相结合,ESG绩效可以有效地预测企业违约事件。合法性理论支持的研究结果表明,企业不仅可以通过提高企业效率和盈利能力来提高企业的可持续性和合法性,还可以通过外部感知、责任和道德实践来提高企业的可持续性和合法性,这些都起到了“保险效应”的作用。因此,政策制定者应鼓励贷款机构将ESG因素纳入商业模式,促进可持续的商业实践,以降低金融风险。这将加速企业采用更清洁的技术,提高治理标准,并加强整体财务稳定性和企业可持续性。

Prolonged Neobroker usage: Analyzing investment behavior and its impact on trading specific financial products 长期使用新经纪商:分析投资行为及其对特定金融产品交易的影响
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2025-11-24 DOI: 10.1016/j.gfj.2025.101222

We study the impact of prolonged trading app usage on the investment behavior of Neobroker users. Therefore, we use representative data for German Neobroker users and general investors from a panel survey conducted three times over a period of 14 months. We show that the financial literacy of Neobroker users increases with the prolonged trading app use but still remains rather low. The annual (non-risk adjusted) return of Neobroker users is generally positively affected by owning derivatives and frequent trading. In addition, we investigate which determinants impact Neobroker users to trade special ETFs, cryptocurrencies, derivatives, and ETCs. We found an impact of risk tolerance, risk assessment of respective financial products, and trading frequency on Neobroker users to hold specific financial products. Surprisingly, the investment information source also influences Neobroker users regarding the trading of all four products.
我们研究了长时间使用交易应用程序对Neobroker用户投资行为的影响。因此,我们使用了德国nebrobroker用户和一般投资者的代表性数据,这些数据来自一项为期14个月的三次小组调查。我们发现,随着交易应用程序使用时间的延长,Neobroker用户的金融知识水平会提高,但仍然相当低。Neobroker用户的年度(非风险调整)回报通常受到拥有衍生品和频繁交易的积极影响。此外,我们还调查了哪些决定因素会影响Neobroker用户交易特殊etf、加密货币、衍生品和etf。我们发现风险承受能力、各自金融产品的风险评估和交易频率对Neobroker用户持有特定金融产品的影响。令人惊讶的是,投资信息源也会影响Neobroker用户对所有四种产品的交易。

Trade policy uncertainty and stock price crash risk: The role of geographic segment disclosure 贸易政策不确定性与股价崩盘风险:地理区域信息披露的作用
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2025-12-30 DOI: 10.1016/j.gfj.2025.101231

This paper aims to examine how trade policy uncertainty (TPU) affects firm-specific stock price crash risk and the extent to which corporate disclosures and governance can mitigate this vulnerability. Using a global panel database of publicly listed firms from 17 countries over the period 2010–2023, we find a positive and significant relationship between TPU and stock price crash risk, suggesting that firms exposed to trade policy shocks are more vulnerable to sudden negative price movements. As a result of opacity, firms with less transparent geographical segment disclosure tend to hoard bad news, suggesting that opacity compounds this tendency. Furthermore, we investigate how segment reporting complexity, supply chain concentration, and governance mechanisms serve as moderating factors. We find that high segment reporting complexity and supply chain concentration exacerbate the TPU-crash risk relationship by increasing operational and informational opacity. The TPU-induced crash risk decreases with strong institutional ownership and enhanced analyst coverage, but increases with high information asymmetry. In light of rising global trade policy uncertainty, geographical segment disclosure, operational structure, and governance are crucial to moderating firm-level financial fragility.
本文旨在研究贸易政策不确定性(TPU)如何影响公司特定的股价崩溃风险,以及公司披露和治理在多大程度上可以减轻这种脆弱性。利用2010-2023年间17个国家上市公司的全球面板数据库,我们发现TPU与股价崩盘风险之间存在显著的正相关关系,这表明受到贸易政策冲击的公司更容易受到突然的负面价格波动的影响。由于不透明,地理区域信息披露不透明的公司倾向于囤积坏消息,这表明不透明加剧了这种趋势。此外,我们研究了分部报告的复杂性、供应链集中度和治理机制如何作为调节因素。研究发现,较高的分部报告复杂性和供应链集中度增加了运营和信息的不透明性,从而加剧了tpu -崩溃风险关系。tpu引发的崩溃风险随着机构所有权的增强和分析师覆盖率的增加而降低,但随着信息不对称的增加而增加。鉴于全球贸易政策不确定性上升,地理部门披露、运营结构和治理对于缓和企业层面的金融脆弱性至关重要。

Managerial overconfidence and corporate environmental, social, and governance performance: International evidence 管理过度自信与企业环境、社会和治理绩效:国际证据
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2026-02-06 DOI: 10.1016/j.gfj.2026.101242

This study examines the impact of managerial overconfidence on corporate environmental, social, and governance (ESG) performance. We argue that strong ESG performance mitigates firm risk by functioning as moral capital during adverse events—an insurance-like buffer that protects firms during adverse events and controversies. Overconfident managers, however, tend to hold overly optimistic expectations about firm outcomes and may therefore discount this moral insurance effect, undervaluing ESG initiatives and ultimately exhibiting weaker ESG performance. Using a comprehensive sample of firms from 51 countries over the period 2009–2018, we find a robust negative association between managerial overconfidence and ESG performance. Firms led by overconfident CEOs exhibit weaker environmental policies, poorer social outcomes, and a higher likelihood of governance-related controversies. Our findings remain stable across multiple endogeneity checks, including propensity score matching, generalized method of moments, two-stage least squares, alternative variable constructions, and subsample analyses across institutional and economic groupings. This study contributes to the growing literature at the intersection of behavioral finance and corporate ESG by highlighting the role of managerial psychology—an often-overlooked factor—in shaping nonfinancial performance. Additional analyses indicate that heightened corporate risk-taking serves as a key transmission mechanism through which managerial overconfidence undermines ESG performance. Overall, the study provides novel and policy-relevant insights into the behavioral foundations of corporate sustainability, demonstrating that executive psychology is a critical—yet often overlooked—determinant of firms' ESG outcomes in global settings.
本研究考察了管理者过度自信对企业环境、社会和治理(ESG)绩效的影响。我们认为,强大的ESG绩效通过在不利事件中充当道德资本——一种类似保险的缓冲,在不利事件和争议中保护公司——来减轻企业风险。然而,过度自信的管理者往往对公司的结果抱有过于乐观的预期,因此可能会低估这种道德保险效应,低估ESG举措,最终表现出较弱的ESG绩效。通过对2009-2018年期间51个国家的公司进行全面抽样,我们发现管理层过度自信与ESG绩效之间存在显著的负相关关系。由过度自信的首席执行官领导的公司表现出较弱的环境政策,较差的社会结果,以及更有可能出现与治理相关的争议。我们的研究结果在多个内质性检验中保持稳定,包括倾向得分匹配、广义矩法、两阶段最小二乘、可选变量结构以及跨制度和经济分组的子样本分析。这项研究通过强调管理心理学——一个经常被忽视的因素——在塑造非财务绩效方面的作用,为行为金融学和企业ESG交叉领域的越来越多的文献做出了贡献。其他分析表明,企业风险承担加剧是管理层过度自信破坏ESG绩效的关键传导机制。总体而言,该研究为企业可持续发展的行为基础提供了新颖的、与政策相关的见解,表明高管心理是全球环境下企业ESG成果的关键决定因素,但往往被忽视。

This paper examines the predictability and implications of sequential credit rating downgrades under the through-the-cycle rating methodology. Using 28,847 firm-year observations for North American corporates, we show that firms partway through downgrade sequences exhibit weaker fundamentals than non-downgraded peers with the same rating, implying interim ratings misstate credit risk. Predictive models of future downgrades achieve up to 75 % accuracy, with out-of-sample tests and feature-importance measures confirming robustness. A simple portfolio exercise illustrates economic significance. Our findings extend the literature on rating inertia and highlight the usefulness of credit-quality signals for anticipating rating actions.
本文研究了在全周期评级方法下,连续信用评级下调的可预测性和影响。通过对28,847家北美公司的年度观察,我们发现,处于降级序列中间的公司比具有相同评级的未降级同行表现出更弱的基本面,这意味着中期评级错误地反映了信用风险。未来降级的预测模型达到75%的准确率,样本外测试和特征重要性测量证实了稳健性。一个简单的投资组合练习说明了其经济意义。我们的研究结果扩展了关于评级惯性的文献,并强调了信用质量信号对预测评级行动的有用性。

Relationship between firm value, environment, social, and governance – Strengths and controversies 企业价值、环境、社会与治理的关系——优势与争议
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2026-01-24 DOI: 10.1016/j.gfj.2026.101238

Previous studies only examined one or two two-way relationships among firm value (FV), environmental, social, and governance strengths (ESG), and ESG controversies (ESG contro). We analyze all three: 1) ESG and FV, 2) ESG contro and FV, and 3) ESG and ESG contro. Using 688 observations from 2008 to 2018 of Indian firms, we determine the optimal lag order, cross-sectional dependence (CD), and stationarity for a panel vector autoregressive (panel VAR) model with system generalized method of moments (GMM). We confirm results with Instrumental Variables - Two-Stage Least Squares (IV-2SLS). First, we examine a bi-directional relationship between ESG and FV; however, we find a unidirectional association that supports good management. Second, we confirm the bidirectionality of ESG contro and FV, suggesting a virtuous circle. A decrease in prior ESG contro enhances FV; then, FV surge lessens ESG contro. Our results also reflect that the firms either augment ESG or diminish ESG contro to enhance their FV eventually. Finally, we confirm the bidirectionality of ESG contro–ESG. We confirm that ESG is not invested until earlier ESG contro has increased, supporting the moral cleansing. Regarding past ESG influencing ESG contro, we highlight the unsolved licensing-consistency puzzle in the literature. Initially, our paper also finds contradictory results. Our panel VAR estimates support moral consistency, while IV-2SLS supports moral licensing. Therefore, we investigate the critical conditions under which firms exhibit moral consistency or moral licensing. We find that firms that do not receive CR awards exhibit moral consistency, while those that do receive CR awards exhibit moral licensing. Thus, it is the first study to examine all three kinds of bidirectional links between ESG, ESG contro, and FV, as well as the role of CR awards in resolving the moral licensing-consistency puzzle.
以前的研究只考察了企业价值(FV)、环境、社会和治理优势(ESG)和ESG争议(ESG控制)之间的一种或两种双向关系。我们分析了这三点:1)ESG和FV, 2) ESG控制和FV,以及3)ESG和ESG控制。利用2008年至2018年印度企业的688个观测值,我们确定了采用系统广义矩量法(GMM)的面板向量自回归(panel VAR)模型的最优滞后阶数、横截面依赖性(CD)和平稳性。我们用工具变量-两阶段最小二乘法(IV-2SLS)来确认结果。首先,我们考察了ESG和FV之间的双向关系;然而,我们发现了一种支持良好管理的单向关联。其次,我们确认了ESG控制和FV的双向性,这是一个良性循环。先前ESG控制的减少会增强FV;然后,FV浪涌减弱ESG控制。我们的研究结果还反映出,企业要么增加ESG控制,要么减少ESG控制,最终都会提高企业的财务价值。最后,我们确认了ESG控制- ESG的双向性。我们确认,在早期ESG控制增加之前,不会投资ESG,支持道德净化。关于过去ESG对ESG控制的影响,我们强调了文献中尚未解决的许可一致性难题。最初,我们的论文也发现了相互矛盾的结果。我们的面板VAR估计支持道德一致性,而IV-2SLS支持道德许可。因此,我们研究了企业表现出道德一致性或道德许可的关键条件。我们发现,未获得企业责任奖励的企业表现出道德一致性,而获得企业责任奖励的企业表现出道德许可。因此,这是第一个研究ESG、ESG控制和FV之间所有三种双向联系,以及责任奖励在解决道德许可-一致性难题中的作用的研究。

Multivariate crash risk and worldwide stock returns 多元崩盘风险与全球股票收益
IF 5.5 2区 经济学 Q1 BUSINESS, FINANCE Pub Date : 2026-06-01 Epub Date: 2025-12-20 DOI: 10.1016/j.gfj.2025.101230

This paper examines the pricing of multivariate crash risk (MCRASH), which measures the conditional probability that a stock crashes when one or more systematic risk factors crash. Using data from 48 countries between 1992 and 2021, we show that MCRASH is a robust predictor of expected stock returns. The premium is stronger in emerging markets and concentrated in cyclical industries, consistent with differences in institutional quality, earnings cyclicality, and macroeconomic exposure. We also document that cultural dimensions condition the pricing of MCRASH. Individualism and uncertainty avoidance strengthen the premium, trust dampens it, and power distance intensifies it during high-volatility states. These results highlight the state-dependent role of culture in shaping investor responses to systemic risk.
本文研究了多元崩溃风险(MCRASH)的定价,它衡量了当一个或多个系统性风险因素崩溃时股票崩溃的条件概率。使用1992年至2021年间48个国家的数据,我们表明MCRASH是预期股票回报的稳健预测因子。这种溢价在新兴市场更为强劲,且集中在周期性行业,这与机构质量、盈利周期性和宏观经济敞口的差异一致。我们还记录了文化维度对MCRASH定价的影响。在高波动状态下,个人主义和不确定性规避强化了溢价,信任抑制了溢价,权力距离强化了溢价。这些结果突出了文化在塑造投资者对系统性风险的反应方面的国家依赖作用。
