In this study, we seek to provide insights into the conflicting findings from prior research about whether the consequences of a cybersecurity breach spillover to non-breached bystander firms in the same industry − a phenomenon known as contagion effects. When considering the implications of a breach for a bystander firm, we suggest investors will rely on the loss heuristic and thus view loss (profit) bystander firms as more (less) likely to suffer a similar breach in the future. This will lead to greater cybersecurity breach contagion effects for loss firms than for profit firms. Furthermore, we propose that internal control quality will mitigate contagion effects and to a greater extent for loss firms than for profit firms. To test our hypotheses, we use a sample of cybersecurity breaches and identify a sample of non-breached bystander firms in the same subindustry as the breached firms. Our findings support our predictions and help explain the mixed findings from research on cybersecurity breach contagion effects. Results should also be informative to boards of directors and firm management considering ways to minimize costs associated with contagion effects.
在本研究中,我们试图就先前研究中关于网络安全漏洞的后果是否会波及同行业中未受漏洞影响的旁观企业这一相互矛盾的结论提供见解,这种现象被称为传染效应。在考虑网络安全漏洞对旁观企业的影响时,我们认为投资者会依赖于损失启发式,从而认为亏损(盈利)的旁观企业在未来遭遇类似漏洞的可能性更大(更小)。这将导致亏损企业的网络安全漏洞传染效应大于盈利企业。此外,我们还提出,内部控制质量将减轻传染效应,并且对亏损企业的影响程度要大于对盈利企业的影响程度。为了验证我们的假设,我们使用了网络安全漏洞样本,并确定了与漏洞企业同属一个子行业的非漏洞旁观企业样本。我们的研究结果支持我们的预测,并有助于解释有关网络安全漏洞传染效应的研究结果的混杂性。对于正在考虑如何最大限度降低与传染效应相关的成本的董事会和公司管理层来说,研究结果也应具有参考价值。

This study delves into the COSO framework to explore the impact of risk disclosure of internal control and media coverage on stock price crash risk. Our findings reveal that effective risk disclosure of internal control plays a crucial role in reducing a company’s stock price crash risk. Additionally, positive and negative media coverage exhibit contrasting effects on crash risk. Notably, the efficacy of internal risk governance significantly shapes the “Double-edged Sword” effect of media monitoring and ultimately influences stock prices. Finally, we uncover the mechanisms through which risk disclosure mitigates stock price crash risk. In summary, our research offers novel insights and practical recommendations for enhancing corporate governance practices.
本研究深入研究了 COSO 框架,探讨了内部控制风险披露和媒体报道对股价暴跌风险的影响。我们的研究结果表明,有效的内部控制风险披露对降低公司股价暴跌风险起着至关重要的作用。此外,正面和负面的媒体报道对股价暴跌风险的影响也截然不同。值得注意的是,内部风险治理的有效性极大地影响了媒体监督的 "双刃剑 "效应,并最终影响股价。最后,我们揭示了风险披露减轻股价暴跌风险的机制。总之,我们的研究为加强公司治理实践提供了新颖的见解和实用的建议。

Historically, literature suggests that a variety of accounting roles will be replaced by Artificial Intelligence (AI) and related technologies; however, in recent years there is a growing recognition that accounting can in fact harness AI’s potential to add value to organisations. Commentators have highlighted the need for increased research exploring accounting and AI and for accounting scholars to consider multi-disciplinary research in this area. This study uses a form of topic modelling to analyse literature exploring AI and related techniques in an accounting context. Latent Dirichlet Allocation (LDA) has been used to enable probabilistic, machine-based interrogation of large volumes of literature. This study applies LDA to the abstracts of 930 peer-reviewed academic publications from a variety of disciplines to identify the most significant accounting and AI topics discussed in the literature during the period 1990 to 2023. Our findings suggest that prior literature reviews based on more traditional methodologies do not capture a comprehensive picture of accounting and AI research. Eleven topic clusters are identified which provide a comprehensive topology of the extant literature discussing accounting and AI and set out an agenda for future research designed to foster academic progress in the area. It also represents one of the first applications of probabilistic topic modelling to accounting literature.

从历史上看,有文献表明,各种会计角色将被人工智能(AI)和相关技术所取代;然而,近年来,越来越多的人认识到,会计实际上可以利用人工智能的潜力为组织增值。评论家们强调,有必要加强对会计与人工智能的研究,会计学者也有必要考虑在这一领域开展多学科研究。本研究采用一种主题建模的形式,来分析在会计背景下探索人工智能及相关技术的文献。Latent Dirichlet Allocation (LDA) 已被用于对大量文献进行基于机器的概率分析。本研究将 LDA 应用于来自不同学科的 930 篇同行评审学术出版物的摘要,以确定 1990 年至 2023 年期间文献中讨论的最重要的会计和人工智能主题。我们的研究结果表明,以往基于更传统方法的文献综述并不能全面反映会计与人工智能研究的情况。我们确定了 11 个主题集群,为讨论会计与人工智能的现有文献提供了一个全面的拓扑结构,并为未来研究制定了一个议程,旨在促进该领域的学术进步。这也是概率主题建模在会计文献中的首次应用。

In the government procurement process, waste and abuses are hard to avoid, and there are usually latencies between the event occurrence and detection works. The continuous audit methodology has been adopted by many public and private firms to actively monitor transactions and detect possible anomalies. Compared to the adoptions in the private sector, implementations of continuous audit and monitoring of government procurement analyses are limited. This study applies the continuous monitoring and audit methodology to the medication procurement data of a Brazilian city government, and it aims to help internal auditors identify exceptions and anomalies in procurements for further investigation. By introducing the comparison of exogenous data, this study further provides cost management opportunities.
在政府采购过程中,浪费和弊端难以避免,而且事件发生和检测工作之间通常存在延迟。持续审计方法已被许多公共和私营企业所采用,以积极监控交易并发现可能的异常情况。与私营部门相比,对政府采购分析实施持续审计和监控的情况还很有限。本研究将持续监控和审计方法应用于巴西某市政府的药物采购数据,旨在帮助内部审计人员发现采购中的异常情况和异常现象,以便进一步调查。通过引入外生数据比较,本研究进一步提供了成本管理机会。

In March 2022, the Securities and Exchange Commission (SEC) proposed the mandatory reporting of cybersecurity risk management policies for public companies. This study aims to explore the potential impact of cybersecurity risk management strategy disclosure on nonprofessional investors. Using a 4 x 1 between-participants experimental design, we examine whether nonprofessional investors’ perceptions and decisions differ between disclosed cybersecurity risk management strategies of self-assessment, self-assessment referencing the National Institute of Standards and Technology (NIST) framework, third-party assurance, and insurance. We find that nonprofessional investors’ willingness to invest is significantly higher for the insurance strategy compared to the third-party cybersecurity examination and self-assessment (without reference to NIST) strategies. Moderated mediation analysis reveals that investors’ perceptions of financial risk moderates the mediating effect of perceived cybersecurity risk management strategy effectiveness on the relation between cybersecurity risk management strategy and likelihood of investment. Our study contributes to regulators, practitioners, and stakeholders concerned about the potential impact of cybersecurity risk management strategy disclosures on nonprofessional investors.

2022 年 3 月,美国证券交易委员会(SEC)提议强制要求上市公司报告网络安全风险管理政策。本研究旨在探讨网络安全风险管理策略披露对非专业投资者的潜在影响。我们采用 4 x 1 参与者之间的实验设计,考察非专业投资者对自我评估、参考框架的自我评估、第三方保证和保险这几种已披露的网络安全风险管理策略的看法和决策是否存在差异。我们发现,与第三方网络安全检查和自我评估(不参考 NIST)策略相比,非专业投资者对保险策略的投资意愿明显更高。调节中介分析显示,投资者对金融风险的感知调节了感知到的网络安全风险管理策略有效性对网络安全风险管理策略和投资可能性之间关系的中介效应。我们的研究有助于监管机构、从业人员和关注网络安全风险管理策略披露对非专业投资者潜在影响的利益相关者。

This paper proposes the concept of artificial intelligence co-piloted auditing, emphasizing the collaborative potential of auditors and foundation models in the auditing domain. The paper discusses the future relationship and interactions of human auditors and AI, imagining an audit setup where auditors’ capabilities are enhanced through artificial intelligence across a variety of audit tasks. To exemplify the potential of this co-piloted audit paradigm, we illustrate a systematic fine-tuning approach to foundation models using Chain-of-Thought prompting. This study showcases how foundation models can work as collaborators flexibly with auditors, enabling the model to accurately identify transactions from instructions. This study provides a detailed description of the formulated prompt protocols and the corresponding responses generated by ChatGPT, ensuring reproducibility. We envision this work as an initial step towards the widespread implementation of co-piloted auditing, paving the way for more efficient, accurate, and insightful audit procedures.

To address the need for reporting and disclosure of cryptocurrency holdings in compliance with the FASB guidance for the use of fair value measurements for cryptocurrency (FASB, 2023), this paper develops a modeling process for reporting entities to measure the market value of cryptocurrencies with limited or no observable transactions. In this valuation model, we consider the last observable market information with time decay, its comparable assets market index, and dynamic real-time market participants’ sentiment and attention. Notably, the application of exogenous variables allows us to maximize the observable inputs in measuring fair value, such as asset classification based on economic traits and market participants’ attention and sentiment measurement with online media textual analytics. We propose a valuation framework and construct a prediction model that can achieve a prediction accuracy of 87 % on target asset resurging prices.

为满足报告和披露加密货币持有情况的需要,以符合美国财务会计准则委员会(FASB)关于加密货币使用公允价值计量的指导意见(FASB,2023 年),本文为报告实体开发了一个建模流程,以计量可观察交易有限或没有的加密货币的市场价值。在该估值模型中,我们考虑了具有时间衰减的最后可观测市场信息、其可比资产市场指数以及动态实时市场参与者的情绪和注意力。值得注意的是,外生变量的应用使我们在衡量公允价值时能够最大限度地利用可观察输入,如基于经济特征的资产分类和利用在线媒体文本分析的市场参与者关注度和情绪衡量。我们提出了一个估值框架,并构建了一个预测模型,该模型对目标资产复牌价格的预测准确率可达 87%。

This study uses analytical models to investigate whether requiring cybersecurity assurance or a particular maturity level for vendors or contractors will help them improve their cybersecurity management. Our findings suggest that, if a supplier decides on its preferred cybersecurity maturity level without knowing what level a contract requires, the supplier is more likely to exert more effort to improve its cybersecurity management. We also show that a buyer can incentivize the supplier to engage in improving cybersecurity risk management by imposing a reduced contractual price or a fine when a breach occurs. Our findings reveal the role played by cybersecurity maturity level assurance and we discuss practical implications.

本研究使用分析模型来调查要求供应商或承包商提供网络安全保证或特定的成熟度是否有助于他们改善网络安全管理。我们的研究结果表明,如果供应商在不知道合同要求的网络安全成熟度水平的情况下决定其首选的网络安全成熟度水平,那么供应商更有可能付出更多努力来改善其网络安全管理。我们还发现,买方可以通过降低合同价格或在发生违约时处以罚款来激励供应商改善网络安全风险管理。我们的研究结果揭示了网络安全成熟度保证所起的作用,并讨论了实际意义。

Digitization is fundamentally changing how organizations create and deliver business value, with information technology (IT) leveraged to improve business processes and controls. Its pervasive effects upon organizations’ risk exposures and performance requires boards’ prudent and integrated consideration of the resultant IT opportunities and risk management. However, IT governance research suggests that boards’ governance of IT is more commonly delegated and relegated to management and committees than integrated as part of their corporate governance practices. In response, our study contributes timely and structured understanding of boards’ roles and the mechanisms required for IT governance to become an integrated component of corporate governance.

数字化正在从根本上改变组织创造和提供业务价值的方式,信息技术(IT)被用来改善业务流程和控制。信息技术对组织的风险敞口和绩效产生了普遍影响,这就要求董事会审慎地综合考虑由此带来的信息技术机遇和风险管理。然而,IT 治理研究表明,董事会对 IT 的治理更多的是委托给管理层和委员会,而不是将其整合为公司治理实践的一部分。作为回应,我们的研究有助于及时、系统地了解董事会的作用以及信息技术治理成为公司治理的一个综合组成部分所需的机制。

Governments shoulder the responsibility of pursuing a variety of sustainability objectives, the consequences of which may not be discernable in traditional reporting frameworks. Environmental, Social, and Governance (ESG) reporting would be a valuable addition to the existing financial, service, and infrastructure aspects of government reporting. While reportable data may be difficult to measure, smart city development strategies dovetail with technologies that facilitate sustainability reporting. Smart city strategies utilize technologies to support and inform municipal governance. This paper proposes a framework of government ESG reporting based on smart city initiatives, details potential steps in the process of government ESG reporting, discusses how smart cities could facilitate ESG reporting, and illustrates potential avenues of analysis using New York City vehicular mobility data as an example. This research sheds light on an under-examined topic, offers a perspective on adding ESG to government reporting, explores how sustainability data can inform government ESG reporting, and demonstrates the utility of smart city data for reporting, assurance, and monitoring.

政府肩负着追求各种可持续发展目标的责任,其后果可能无法在传统的报告框架中发现。环境、社会和治理 (ESG) 报告是对现有政府报告中财务、服务和基础设施方面的宝贵补充。虽然可报告的数据可能难以衡量,但智慧城市发展战略与促进可持续发展报告的技术相吻合。智慧城市战略利用技术来支持和指导市政管理。本文提出了基于智慧城市倡议的政府环境、社会和治理报告框架,详细介绍了政府环境、社会和治理报告过程中的潜在步骤,讨论了智慧城市如何促进环境、社会和治理报告,并以纽约市车辆流动数据为例说明了潜在的分析途径。这项研究揭示了一个未得到充分研究的课题,提供了将环境、社会和公司治理纳入政府报告的视角,探讨了可持续发展数据如何为政府环境、社会和公司治理报告提供信息,并展示了智慧城市数据在报告、保证和监控方面的实用性。
