Nonfinancial firms have increasingly engaged in shadow banking activities. Using data from Chinese A-share nonfinancial firms, we empirically examine how such activities affect equity mispricing. The results indicate that shadow banking by nonfinancial firms is positively associated with equity mispricing. This finding still holds when we address potential endogeneity problems and use alternative proxies. This relationship is less pronounced among firms with higher levels of digitalization, stronger corporate governance, more market development business environments, and state-ownership structure, suggesting that information asymmetry, agency problems, and regulatory uncertainty are key underlying mechanisms. Further analysis shows that increased shadow banking activity raises stock price volatility, heightens crash risk, and increases the cost of equity, with these effects operating in part through equity mispricing. Our study extends the literature on equity mispricing and highlights the consequences of nonfinancial firms' engagement in shadow banking activities in the capital market.
非金融企业越来越多地参与影子银行活动。利用中国a股非金融公司的数据,我们实证研究了此类活动如何影响股票错误定价。结果表明,非金融企业的影子银行业务与股票错误定价呈正相关。当我们解决潜在的内生性问题并使用替代代理时,这一发现仍然成立。这一关系在数字化水平较高、公司治理水平较高、商业环境市场化程度较高和国有企业结构较高的企业中不太明显,这表明信息不对称、代理问题和监管不确定性是关键的潜在机制。进一步的分析表明,影子银行活动的增加增加了股价波动,增加了崩盘风险,并增加了股权成本,这些影响在一定程度上是通过股票错误定价产生的。我们的研究扩展了关于股票错误定价的文献,并强调了非金融公司参与资本市场影子银行活动的后果。

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。

This study explores the effect of zero-cost employee stock ownership plans (zero-cost ESOPs) on corporate innovation. Based on staggered Difference-in-Differences (DID) method, the empirical results demonstrate that zero-cost ESOPs significantly promote corporate innovation, and the result is validated by a series of robustness and endogeneity tests. Mechanism analysis reveals that zero-cost ESOPs enhance corporate innovation by improving the human capital structure through attracting more highly educated and technically skilled employees, which widens the salary gap. Furthermore, the positive effect is more pronounced for firms with lower average salaries, industry competition, and executive shareholding. Most importantly, compared with traditional ESOPs, zero-cost ESOPs exhibit a stronger positive influence on corporate innovation, particularly in fostering independent innovation rather than collaborative innovation with external firms.
本研究探讨零成本员工持股计划(零成本ESOPs)对企业创新的影响。基于交错差分法(交错差分法)的实证结果表明,零成本员工持股计划显著促进了企业创新,并通过一系列鲁棒性和内质性检验对结果进行了验证。机制分析表明,零成本员工持股计划通过吸引更多高学历和技术熟练的员工来改善人力资本结构,从而促进企业创新,从而扩大薪酬差距。此外,对于平均工资、行业竞争和高管持股比例较低的公司,积极效应更为明显。最重要的是,与传统的员工持股计划相比,零成本员工持股计划对企业创新表现出更强的积极影响,特别是在促进自主创新而不是与外部企业协同创新方面。

Only attractive women are welcome: Board bias and CEO selection 只欢迎有魅力的女性:董事会偏见和CEO选择

CEOs matter, and beauty matters. Based on social identity theory, we argue that women and men are likely to be held to different beauty standards by the boards of directors when these boards select the new CEO. Our empirical results support our arguments. Specifically, we investigate 959 CEO turnovers in non-financial S&P 1500 firms in the period from 2008 to 2022. We find that newly appointed female CEOs are significantly more attractive than their male peers. Thus, the median female CEO is more attractive than a male CEO at the 75th percentile level. We find no indication of an economic rationale for such a biased beauty preference. When investors are informed of the new CEO, they value CEO beauty equally across the two genders (i.e., no gender bias). The discrimination by the boards of directors seems to be related to women's minority status (i.e., we get similar results for non-white candidates) rather than the sexualization of women although we cannot rule out that both may coincide. Our findings are robust and economically significant. Thus, they are important in understanding the lack of gender equality and the avenues through which women face (beauty) discrimination in the upper echelons.
首席执行官很重要,美貌也很重要。基于社会认同理论,我们认为当董事会选择新的CEO时,女性和男性可能会被董事会持有不同的审美标准。我们的实证结果支持我们的论点。具体而言,我们调查了2008年至2022年期间标准普尔1500强非金融企业中959名CEO的离职情况。我们发现,新上任的女性ceo明显比男性同行更具吸引力。因此,在第75个百分位数的水平上,女性CEO比男性CEO更具吸引力。我们没有发现任何迹象表明这种有偏见的美貌偏好有经济依据。当投资者得知新任CEO的消息后,他们对CEO美貌的评价是男女平等的(即没有性别偏见)。董事会的歧视似乎与女性的少数民族地位有关(即,我们对非白人候选人得到了类似的结果),而不是女性的性化,尽管我们不能排除两者可能同时发生。我们的发现是可靠的,具有经济意义。因此,它们对于理解性别平等的缺乏以及女性在上层面临(美貌)歧视的途径非常重要。

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。

This research delves into the cash flow underwriting in the U.S. property-casualty insurance market, a strategic approach in which insurance companies trade off underwriting profits in hopes of higher investment returns. Spanning from 1954 to 2023, this study utilizes nonlinear autoregressive distributed lag (NARDL) and multiple threshold NARDL (MTNARDL) models to uncover how interest rate fluctuations affect underwriting profits and investment income ratios. We discovered compelling differences: while the short-tail line aligns with rational market behavior, the long-tail line reacts significantly, echoing the nature of cash flow underwriting. At the aggregate industry level, the dominance of cash flow underwriting in the long run is primarily driven by these long-tail business lines, which account for a substantial share of underwriting exposure. Furthermore, a pattern of long-run asymmetric adjustment is also observed between investment income ratios and interest rates, indicating that while underwriting profits decline with rising interest rates, investment income can offset these losses to a certain extent. Through asymmetric causality tests, we further illustrate how positive and negative interest rate shocks uniquely influence profitability across various business lines. This study not only bridges conflicting theories of rational markets and strategic underwriting but also equips industry stakeholders with critical insights to navigate the complex rhythms of the insurance market.
本研究深入研究了美国财产险市场的现金流承保,这是保险公司为了获得更高的投资回报而权衡承保利润的一种战略方法。从1954年到2023年,本研究利用非线性自回归分布滞后(NARDL)和多阈值NARDL (MTNARDL)模型来揭示利率波动对承保利润和投资收益比率的影响。我们发现了令人信服的差异:短尾线与理性的市场行为一致,而长尾线反应明显,与现金流承保的本质相呼应。在整个行业层面,长期来看,现金流承销的主导地位主要是由这些长尾业务线驱动的,它们占承销风险敞口的很大份额。此外,投资收益比率与利率之间也存在长期的不对称调整模式,这表明尽管承保利润随着利率的上升而下降,但投资收益可以在一定程度上抵消这些损失。通过非对称因果检验,我们进一步说明了正负利率冲击如何独特地影响各个业务线的盈利能力。这项研究不仅将理性市场和战略承保的理论冲突联系起来,而且还为行业利益相关者提供了关键的见解,以驾驭保险市场的复杂节奏。

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。

Retail investors' green interactions—their oversight and recommendations on corporate climate risks through official interactive platforms—have become a growing informal governance mechanism as climate change gains global prominence. Drawing on social exchange theory, this study examines how such interactions between retail investors and listed firms influence corporate climate risk exposure (CRE). Using data from China's investor-firm interactive platforms covering 1798 firms from 2014 to 2022, we find that green interactions significantly reduce CRE, with stronger effects among firms exhibiting higher social responsibility conformity and larger retail investor bases. Advocacy-oriented and information-oriented messages are most effective, and their impact is amplified by firms' response quality. We identify three mechanisms behind this relationship: heightened climate risk perception, lower information transmission costs, and strengthened investor trust. These findings deepen understanding of retail investor activism in corporate climate governance and offer insights for integrating grassroots engagement into climate policy and financial regulation.
随着气候变化日益成为全球关注的焦点,散户投资者的绿色互动——他们通过官方互动平台对企业气候风险的监督和建议——已经成为一种日益增长的非正式治理机制。本研究运用社会交换理论,探讨散户投资者与上市公司之间的互动如何影响企业气候风险暴露。利用涵盖2014 - 2022年中国1798家企业的投资者-企业互动平台数据,我们发现绿色互动显著降低了CRE,且在社会责任一致性较高、散户投资者基数较大的企业中效果更强。以宣传为导向和以信息为导向的信息是最有效的,它们的影响被企业的反应质量放大。我们确定了这种关系背后的三个机制:提高气候风险感知、降低信息传递成本和加强投资者信任。这些发现加深了对公司气候治理中散户投资者行动主义的理解,并为将基层参与纳入气候政策和金融监管提供了见解。

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。

Share pledging by controlling shareholders and firm investment efficiency: Evidence from China 控股股东股权质押与企业投资效率:来自中国的证据

Share pledging is not strictly regulated in emerging markets, making it into a mechanism for controlling shareholders to cash out financing. Using data from Chinese listed companies (2008–2020), this study examines the relationship between controlling shareholder share pledging and corporate investment efficiency by incorporating the reinvestment behavior of pledged funds into an analytical framework. Results reveal a significant negative correlation between share pledging and investment efficiency by reducing information transparency, weakening corporate social responsibility(CSR), and damaging the effectiveness of internal control. However, pledged fund inflow can alleviate financing constraints and function as a reservoir to improve investment efficiency. When pledged funds flow into the enterprise, the reservoir effect becomes dominant, particularly in firms experiencing underinvestment issues. In this scenario, share pledges alleviate financing constraints, improve corporate investment efficiency. In contrast, when pledged funds flow out of the enterprise, weakened corporate governance from equity pledges triggers the tunneling effect, which exacerbates agency conflicts and reduces investment efficiency. Further analysis reveals that the tunneling effect is weaker for companies with high audit quality, strong media attention, and check-and-balance ownership. These findings, which remain robust after a series of tests including instrumental variable method(IV), propensity score matching(PSM), and alternative variable measurements, contribute to understanding share pledges' actual impact and mechanisms on firm-level resource allocation, yielding significant theoretical and practical insights for improving corporate governance and regulatory systems in emerging markets.
在新兴市场,股权质押并未受到严格监管,这使其成为控股股东套现融资的一种机制。本文利用2008-2020年中国上市公司的数据,将质押资金的再投资行为纳入分析框架,考察了控股股东股权质押与公司投资效率之间的关系。结果表明,股权质押与投资效率之间存在显著的负相关关系,降低了信息透明度,削弱了企业社会责任,损害了内部控制的有效性。而质押资金流入可以缓解融资约束,起到蓄水池的作用,提高投资效率。当质押资金流入企业时,蓄水池效应就占主导地位,特别是在遇到投资不足问题的公司。在这种情况下,股权质押缓解了融资约束,提高了企业投资效率。而当质押资金流出企业时,股权质押导致的公司治理弱化引发了隧道效应,加剧了代理冲突,降低了投资效率。进一步分析发现,对于审计质量高、媒体关注度强、所有权制衡的公司,隧道效应较弱。这些发现在经过工具变量法(IV)、倾向得分匹配(PSM)和替代变量测量等一系列测试后仍然稳健,有助于理解股权质押对公司层面资源配置的实际影响和机制,为改善新兴市场的公司治理和监管体系提供重要的理论和实践见解。
