US Securities and Exchange Commission (SEC) enforcement actions are intended to protect investors and limit expropriation by firm insiders, but these SEC actions could affect insiders' incentives to contribute to value‐enhancing activities. Therefore, we explore how corporate innovation and performance respond to insider trading restrictions imposed by regulators and firms. Using manually collected data on SEC indictments against corporate insiders, we document more innovative activity following external insider trading restrictions. External restrictions are also followed by higher corporate investment, capital access, and operating performance. Similarly, internal blackout restrictions to insider trading are linked to more innovation as well. We use SEC and congressional rule changes as quasi‐natural experiments resulting in shocks in enforcement and indictments for identification and inference. Our results suggest insider trading restrictions and enforcement actions affect subsequent firm activities and managerial decisions by protecting outside investment, resulting in more investment in innovation.
美国证券交易委员会(SEC)的执法行动旨在保护投资者并限制公司内部人员的侵占行为,但这些执法行动可能会影响内部人员对价值提升活动做出贡献的积极性。因此,我们探讨了企业创新和绩效如何应对监管机构和企业施加的内幕交易限制。利用人工收集的美国证券交易委员会对公司内部人的起诉数据,我们记录了外部内幕交易限制后更多的创新活动。受到外部限制后,企业投资、资本获取和经营业绩也会随之提高。同样,对内幕交易的内部封锁限制也与更多创新有关。我们将美国证券交易委员会(SEC)和国会的规则变化作为准自然实验,通过执法和起诉的冲击来进行识别和推断。我们的研究结果表明,内幕交易限制和执法行动会通过保护外部投资来影响公司的后续活动和管理决策,从而导致更多的创新投资。

We examine the determinants of mutual fund partial liquidation and the effect of a negative shock to fund size on performance. We find that older funds from a smaller family with a large number of share classes are more likely to conduct partial liquidation. As fund size decreases after partial liquidation, its performance improves. This effect is more pronounced for funds with stronger pre‐event liquidity constraint and funds that subsequently experience a larger decrease in liquidity, suggesting that liquidity constraint is a contributing factor of fund performance. These findings are consistent with mutual funds having decreasing returns to scale.
我们研究了共同基金部分清算的决定因素以及基金规模的负面冲击对业绩的影响。我们发现,规模较小、股份类别较多的老基金更有可能进行部分清算。随着部分清算后基金规模的缩小,其业绩也会有所改善。对于事件发生前流动性约束较强的基金和随后流动性下降幅度较大的基金,这种效应更为明显,表明流动性约束是影响基金业绩的一个因素。这些发现与共同基金的规模收益递减相一致。

This study examines the association between artificial intelligence innovation (AII) and stock price crash risk (SPCR). AII serves as a governance mechanism that can bolster strength in internal controls, leading to increased financial transparency and thereby reducing the likelihood of future SPCR. The results hold after accounting for possible endogeneity issues Further, we find that monitoring through corporate governance mechanisms, level of following by equity analysts, and the reduced information asymmetry constitute important channels that mediate the association between AII and SPCR. Additionally, the relationship between AII and SPCR varies across corporate life cycle stages and workplace culture.
本研究探讨了人工智能创新(AII)与股价暴跌风险(SPCR)之间的关联。人工智能创新作为一种治理机制,可以加强内部控制,提高财务透明度,从而降低未来发生股价暴跌风险的可能性。此外,我们还发现,公司治理机制的监督、股票分析师的关注程度以及信息不对称程度的降低构成了 AII 与 SPCR 之间关系的重要中介渠道。此外,AII 与 SPCR 之间的关系因公司生命周期阶段和工作场所文化而异。

We use tail events at different levels of severity to define an asset's tail risk and to decompose the latter into a systematic and an idiosyncratic component. The systematic component captures an asset's tendency to experience joint tail losses with the market and generalizes a classic tail dependence coefficient. However, the idiosyncratic component consists of two parts: idiosyncratic tail risk that leads to asset‐specific tail losses and tail risk cushioning that dampens the tail losses emanating from the market. Tail risk cushioning is a novel concept that arises naturally in our framework, is consistent with the previous two and completes the taxonomy of tail risk. We examine the performance of our tail risk decomposition on a large dataset, confirming some previous results on tail risk and uncovering new theoretical and empirical findings.
我们使用不同严重程度的尾部事件来定义资产的尾部风险,并将后者分解为系统性和特异性两部分。系统性部分反映了资产与市场共同经历尾部损失的趋势,并概括了经典的尾部依赖系数。然而,特异性部分由两部分组成:导致特定资产尾部损失的特异性尾部风险和抑制市场尾部损失的尾部风险缓冲。尾部风险缓冲是一个新概念,在我们的框架中自然产生,与前两者一致,并完善了尾部风险的分类。我们在一个大型数据集上检验了尾部风险分解的性能,证实了之前关于尾部风险的一些结果,并揭示了新的理论和实证发现。

Personal connections (based on prior employment, educational, or social club membership overlaps) between top executives and board members of the bidding firm and those of the bidder financial advisor affect Mergers and Acquisition (M&A) outcomes. M&A deals where bidder top managers share past personal work‐related connections with their advisors are associated with 1.7% lower bidder announcement returns compared to the returns for deals without such connections. We also show M&A deals advised by personally connected financial advisors are more likely to be completed but take longer to get finalized. Last, when connections exist, the bidder CEO receives a higher cash bonus upon completion of the deal, and the financial advisors are rewarded by higher advisor fees. Overall, our findings suggest that personal connections between bidders and their financial advisors could be detrimental.
竞标公司高层管理人员和董事会成员与竞标方财务顾问之间的个人联系(基于之前的工作、教育或社交俱乐部会员身份的重叠)会影响并购(M&A)的结果。在并购交易中,如果竞标公司高层管理人员与他们的顾问在过去的个人工作方面有联系,那么竞标公司的公告回报率就会比没有这种联系的交易低 1.7%。我们还发现,由有个人关系的财务顾问提供建议的 M&A 交易更有可能完成,但需要更长的时间才能敲定。最后,如果存在联系,竞标者首席执行官在交易完成后会获得更高的现金奖励,而财务顾问则会获得更高的顾问费。总之,我们的研究结果表明,投标人与其财务顾问之间的个人联系可能是有害的。

We examine the evolution of lead venture capital firm (VC) ownership after their portfolio companies (PCs) are publicly listed. We find that, on average, lead VCs retain their shares for three years post‐IPO. Higher liquidity pressure and better stock market performance lead to faster VC exits, while higher VC reputation, better VC monitoring, and higher quality PCs lead to slower exits. VCs mostly use sales in the open market, share distributions, and mergers and acquisitions to divest their shares. Higher liquidity pressure incentivizes VCs to use majority share distributions, while better stock market performance increases their preference for continuous sales.
我们研究了领头风险投资公司(VC)在其投资组合公司(PC)公开上市后所有权的演变。我们发现,领头风险投资公司在首次公开募股后平均保留股份三年。较高的流动性压力和较好的股市表现会导致风险投资更快地退出,而较高的风险投资声誉、较好的风险投资监控和较高质量的个人电脑则会导致较慢的退出。风险投资公司大多通过公开市场销售、股份分配和并购来剥离股份。较高的流动性压力促使风险投资公司采用多数股权分配的方式,而较好的股市表现则使其更倾向于连续出售。

In this article, we examine whether and how small investors’ social media activity is associated with subsequent bond credit spreads. We use extensive data from posts/comments on social media 30 days before the bond issuance announcement date to identify their implied power and find that the more posts/comments, the smaller the bond issuance spreads. We further find that information quality improvement of posts increases this negative relation between social media activity and bond cost, and that posts directly related to issuers’ fundamentals and/or debt financing drive our main results. Additional tests show that the effect is more salient when there is a greater demand for information quality or when macroeconomic conditions worsen.
在本文中,我们研究了小投资者的社交媒体活动是否以及如何与随后的债券信用利差相关联。我们利用债券发行公告日前 30 天在社交媒体上发帖/评论的大量数据来识别其隐含的力量,发现发帖/评论越多,债券发行利差越小。我们进一步发现,帖子信息质量的提高会增加社交媒体活动与债券成本之间的负相关关系,而与发行人基本面和/或债务融资直接相关的帖子会推动我们的主要结果。其他测试表明,当对信息质量有更高要求或宏观经济状况恶化时,这种效应会更加突出。

Project risk and the bank monitored credit line 项目风险和银行监控的信贷额度
IF 3.5 3区 经济学 Q3 BUSINESS, FINANCE Pub Date : 2024-05-28 DOI: 10.1111/jfir.12411
Eric Van Tassel
In this paper we investigate the role a monitored credit line plays in managing a firm's liquidity needs and influencing the firm's project risk. We develop a theoretical model where a firm finances a risky project that is subject to a liquidity shock. External lenders are imperfectly informed about both project risk and the firm's liquidity, which leads to moral hazard. We identify conditions under which it is optimal for the firm to fund the project using a term loan from a less informed lender and manage liquidity using a line of credit from an informed lender.
在本文中,我们研究了受监控的信贷额度在管理公司流动性需求和影响公司项目风险方面所起的作用。我们建立了一个理论模型,在这个模型中,企业为一个受到流动性冲击的高风险项目提供融资。外部贷款人对项目风险和公司流动性的了解并不完全,这导致了道德风险。我们确定了在哪些条件下,企业利用信息不完全的贷款人提供的定期贷款为项目提供资金,并利用信息完全的贷款人提供的信贷额度管理流动性是最优的。

Synthetic long stock and option trading: Evidence from stock splits 合成多头股票和期权交易:股票分割的证据

Yifan Liu, Louis R. Piccotti
We theoretically and empirically identify synthetic long stock as an alternative driver of option trading. Our model proves that the use of synthetic long stocks by capital‐constrained traders contributes to at‐the‐money (ATM) option trading. Using an event study based on stock splits, we document empirical evidence consistent with the model's predictions. ATM option trading declines after stock splits, and these declines are more pronounced for stock splits with higher stock split factors and for more illiquid stocks but are less pronounced for more illiquid options. Our study implies that option trading can occur even without information or opinion dispersion.
我们从理论和实证角度将合成多头股票确定为期权交易的另一种驱动力。我们的模型证明,资本受限的交易者使用合成多头股票有助于价内(ATM)期权交易。利用基于股票拆分的事件研究,我们记录了与模型预测一致的经验证据。股票拆分后,ATM 期权交易量会下降,而且股票拆分系数越高、流动性越差的股票,ATM 期权交易量下降的幅度越大,但流动性越差的期权,ATM 期权交易量下降的幅度越小。我们的研究表明,即使没有信息或意见分歧,期权交易也会发生。

MIDAS and dividend growth predictability: Revisiting the excess volatility puzzle MIDAS 和股息增长的可预测性:重新审视过度波动之谜

We examine dividend growth predictability and the excess volatility puzzle across a large sample of international equity markets using a mixed‐frequency data sampling (MIDAS) regression approach. We find that accounting for dividend seasonality under the MIDAS framework significantly improves dividend growth predictability compared to simple regressions with annually aggregated data. Moreover, variance bounds tests that allow for nonstationary dividends consistently fail to reject the market efficiency hypothesis across all countries. Our findings suggest that the common rejection of market efficiency in the literature is most likely driven by the annual aggregation of dividend data as well as by the assumption of stationary dividends.
我们采用混合频率数据抽样(MIDAS)回归方法,研究了大量国际股票市场样本的股息增长可预测性和超额波动率之谜。我们发现,与使用年度汇总数据进行简单回归相比,在 MIDAS 框架下考虑股息季节性可显著提高股息增长的可预测性。此外,在所有国家,允许非平稳股息的方差边界检验始终无法拒绝市场效率假设。我们的研究结果表明,文献中对市场效率的普遍否定很可能是由股息数据的年度汇总以及股息静态假设造成的。
