We study how firms respond to online customer reviews in a competitive market where they jostle with one another for sales based on online ratings. The focus of this paper is on how firms can optimally manage their ratings through management response and how review ratings affect the sales and profits of competing firms. We develop a controlled diffusion process to model the coevolution of sales and ratings as a function of the response strategy chosen to maximize profit over time. Our model considers a variety of factors, such as profit margin and customer rating sensitivity, that influence a firm’s effort to manage ratings and subsequently its sales and profits. More response effort needs to be exerted to manage ratings when either the profit margin of a tour is very high or customers are very sensitive to ratings. We estimate our model using data on Ctrip’s tours that include each tour’s sales, reviews, prices, and tour features. We find that consumers anchor their beliefs in the mean market rating and that their purchase decisions depend on the tour’s rating relative to this anchor. Thus, relative, rather than absolute, ratings matter. Our study informs firms on how competition and other primitives impact their efforts to manage ratings and hence profit. Our methodology allowed us to conduct “what-if” analyses, for example, to study what would happen to the review ratings, sales, and profits of a tour if a firm adopted a different response strategy. We were also able to provide turnaround strategies for struggling tours, i.e., factors that a loss-making tour should change if it wishes to make a positive profit. Ultimately, we conducted a competitive analysis that allowed us to modify certain parameters that affect the intensity of competition and hence the sales and the profits of competing tours. Finally, we demonstrate the flexibility of the model by extending it to incorporate multiple state variables that might affect the response strategy.
我们研究公司如何在一个竞争激烈的市场中对在线客户评论做出反应,在这个市场中,他们根据在线评级相互争夺销售。本文的重点是公司如何通过管理反应来优化管理他们的评级,以及评论评级如何影响竞争公司的销售和利润。我们开发了一个受控的扩散过程来模拟销售和评级的共同进化,作为选择的响应策略的函数,以最大化利润。我们的模型考虑了各种因素,如利润率和客户评级敏感性,这些因素会影响公司管理评级的努力,进而影响其销售和利润。当旅游的利润率非常高或客户对评级非常敏感时,需要更多的响应工作来管理评级。我们使用携程旅游的数据来估计我们的模型,这些数据包括每个旅游的销售、评论、价格和旅游功能。我们发现,消费者将他们的信念锚定在平均市场评级上,他们的购买决策取决于与此锚定相关的旅游评级。因此,相对评级比绝对评级更重要。我们的研究告诉公司竞争和其他原始因素如何影响他们管理评级和利润的努力。我们的方法允许我们进行“假设”分析,例如,研究如果一家公司采用不同的应对策略,对旅游的评论评级、销售和利润会产生什么影响。我们还能够为陷入困境的旅游提供扭亏为盈的策略,也就是说,如果亏损的旅游希望获得正利润,就应该改变这些因素。最后,我们进行了一项竞争分析,使我们能够修改影响竞争强度的某些参数,从而影响竞争旅游的销售和利润。最后,我们通过将模型扩展为包含可能影响响应策略的多个状态变量来展示模型的灵活性。

Online health communities (OHCs) play an important role in enabling patients to exchange information and obtain social support from each other. However, do OHC interactions always benefit patients? In this research, we investigate different mechanisms by which OHC content may affect patients’ emotions. Specifically, we notice users can read not only emotional support intended to help them but also emotional support targeting other persons or posts that are not intended to generate any emotional support (auxiliary content). Drawing from emotional contagion theories, we argue that even though emotional support may benefit targeted support seekers, it could have a negative impact on the emotions of other support seekers. Our empirical study on an OHC for depression patients supports these arguments. Our findings are new to the literature and have critical practical implications since they suggest that we should carefully manage OHC-based interventions for depression patients to avoid unintended consequences. We design a novel deep learning model to differentiate emotional support from auxiliary content. Such differentiation is critical for identifying the negative effect of emotional support on unintended recipients. We also discuss options to alter the intervention volume, length, and frequency to tackle the challenge of the negative effect.
在线卫生社区(OHCs)在使患者能够相互交换信息和获得社会支持方面发挥着重要作用。然而,OHC相互作用是否总是对患者有益?在本研究中,我们探讨了OHC含量影响患者情绪的不同机制。具体来说,我们注意到用户不仅可以阅读旨在帮助他们的情感支持,还可以阅读针对其他人的情感支持或不打算产生任何情感支持的帖子(辅助内容)。根据情绪传染理论,我们认为尽管情绪支持可能有利于目标寻求支持者,但它可能对其他寻求支持者的情绪产生负面影响。我们对抑郁症患者OHC的实证研究支持了这些观点。我们的发现对文献来说是新的,具有重要的实际意义,因为它们建议我们应该仔细管理基于ohc的抑郁症患者干预措施,以避免意想不到的后果。我们设计了一个新的深度学习模型来区分情感支持和辅助内容。这种区分对于识别情感支持对非预期接受者的负面影响至关重要。我们还讨论了改变干预量、长度和频率的选择,以应对负面影响的挑战。

We examine the impact of firm social media engagement on sales performance, answering “whether,” “what,” and “how” questions. The study uses a quasi-experimental design in a social e-commerce setting, for which propensity score matching and difference-in-differences methods quantify a mean 20.67% sales increase after firm social media adoption. We also find that firms that sell low-involvement products benefit more from social media adoption, compared to those that sell high-involvement products. Further, in terms of how to manage social media engagement, we find that informative content, in general, is effective for sales of high-involvement products, whereas promotional content, a new type of content discovered in this study, is more beneficial for sales of low-involvement products. Meanwhile, more social media followers generate better firm sales performance. We used instrumental variables and the control function method to address endogeneity issues and conducted robustness checks to support our conclusions. This study sheds light on the value of firm social media, particularly regarding industry differences and firm know-how.
我们考察了企业社交媒体参与对销售业绩的影响,回答了“是否”、“什么”和“如何”的问题。该研究在社交电子商务环境中使用了准实验设计,其中倾向得分匹配和差异中的差异方法量化了企业采用社交媒体后平均20.67%的销售额增长。我们还发现,与销售高参与度产品的公司相比,销售低参与度产品的公司从社交媒体采用中获益更多。此外,在如何管理社交媒体参与方面,我们发现,通常情况下,信息性内容对高参与产品的销售是有效的,而促销性内容是本研究发现的一种新的内容类型,对低参与产品的销售更有利。同时,更多的社交媒体关注者会带来更好的公司销售业绩。我们使用工具变量和控制函数方法来解决内生性问题,并进行鲁棒性检查来支持我们的结论。这项研究揭示了企业社交媒体的价值,特别是在行业差异和企业知识方面。

It Depends on When You Search 这取决于你什么时候搜索

Existing studies have found that online search is a revealed measure for investor attention and a useful predictor of stock returns. We study the heterogeneity in retail investor attention by comparing search conducted on weekdays vs. weekends and investigate the price pressure channel and information processing channel for stock return predictability. According to the information processing channel, weekends afford retail investors more time for the intensive cognitive analysis necessary to make better predictions. Alternatively, weekend search might better capture the price pressure from retail investors’ trading activities. We provide empirical results that support the information processing channel. We first show that weekend search, rather than weekday search, predicts large-cap stock returns in both the cross-section and time series. Additionally, our findings on retail trading activity contradict the price pressure channel in that weekday search, rather than weekend search, leads to a subsequent retail order imbalance. Overall, our study contributes to the literature on the predictive power of online search on stock returns, which has mainly focused on the price pressure channel, which yields significant results for small-cap stocks only.
已有研究发现,在线搜索是衡量投资者关注程度的一种显着指标,也是预测股票收益的有用指标。我们通过比较工作日和周末的搜索来研究散户投资者注意力的异质性,并研究价格压力通道和信息处理通道对股票收益可预测性的影响。根据信息处理渠道,周末为散户投资者提供了更多的时间进行密集的认知分析,以做出更好的预测。另外,周末搜索或许能更好地捕捉散户交易活动带来的价格压力。我们提供了支持信息处理通道的实证结果。我们首先表明,在横截面和时间序列上,周末搜索比工作日搜索更能预测大盘股的回报。此外,我们对零售交易活动的研究结果与工作日搜索的价格压力通道相矛盾,而不是周末搜索,导致随后的零售订单失衡。总体而言,我们的研究有助于在线搜索对股票收益的预测能力的文献,这些文献主要集中在价格压力通道上,仅对小盘股产生显著结果。

Experts vs. Non-Experts in Online Crowdfunding Markets 在线众筹市场的专家vs.非专家

The growth of crowdfunding markets that include both expert and nonexpert investors will soon accelerate due to recent changes in Securities Exchange Commission (SEC) regulations. Prior work has suggested that nonexperts (1) may benefit from experts’ participation via mimicking their trades, but (2) will also face a cost, as experts crowding nonexperts out of the best opportunities will ensure that nonexperts will suffer lower returns than experts. Traditional economic theory holds that the crowding effect means that the relative importance of nonexperts in the market will decline over time until they become unimportant. Exploiting a unique period in one crowdfunding market (Prosper.com) that allowed us to directly estimate the net cost of competing with better-informed experts, we found that the net negative effects of expert participation on nonexperts are small. We used simulations to both better understand (1) the market characteristics and crowdfunding platform choices that influence experts’ and nonexperts’ returns, their return gap, and the extent to which nonexperts are better or worse off relative to a market without expert participation, and (2) the factors that may contribute to the small expert/nonexpert Prosper return gap.
由于最近美国证券交易委员会(SEC)法规的变化,包括专家和非专业投资者在内的众筹市场的增长将很快加速。先前的研究表明,非专家(1)可以通过模仿专家的交易从他们的参与中受益,但(2)也将面临成本,因为专家将非专家挤出最佳机会,这将确保非专家的回报低于专家。传统的经济理论认为,拥挤效应意味着非专家在市场中的相对重要性会随着时间的推移而下降,直到他们变得不重要。利用一个众筹市场(Prosper.com)的独特时期,我们可以直接估算与消息更灵通的专家竞争的净成本,我们发现专家参与对非专家的净负面影响很小。我们使用模拟来更好地理解(1)影响专家和非专家回报的市场特征和众筹平台选择,他们的回报差距,以及非专家相对于没有专家参与的市场的更好或更差的程度,以及(2)可能导致专家/非专家回报差距较小的因素。

Data breaches can severely damage a firm’s reputation and its customers’ confidence. Firms must therefore continuously invest in security measures to prevent such breaches. However, the effectiveness of security investment has been questioned by both practitioners and academics. We illustrate the bidirectional dynamic relationship between information technology (IT) investment and data breaches moderated by threat and countermeasure security awareness using an eight-year panel of 311 U.S.-listed firms to provide empirical evidence that threat awareness broadens firms’ scope for addressing data-breach issues by investing more in IT than in security. Countermeasure awareness equips firms with sufficient knowledge and experience to ensure effective implementation of IT, which provides more comprehensive protection than security investment alone. Our results suggest that firms should evolve beyond the reactive mindset of solely upgrading security and begin nurturing both threat awareness and countermeasure awareness to address the underlying IT system issues that are the cause of data breaches.
数据泄露会严重损害公司的声誉和客户的信心。因此,企业必须不断投资于安全措施,以防止此类违规行为。然而,证券投资的有效性一直受到实践者和学者的质疑。我们通过对311家美国上市公司进行为期8年的调查,说明了信息技术(IT)投资与数据泄露之间的双向动态关系,该关系受到威胁和对策安全意识的调节,并提供了经验证据,表明威胁意识通过在IT方面的投资多于在安全方面的投资,扩大了公司解决数据泄露问题的范围。对策意识为企业提供了足够的知识和经验,以确保有效实施IT,这比单独的安全投资提供了更全面的保护。我们的研究结果表明,企业应该超越仅仅升级安全的被动思维,并开始培养威胁意识和对策意识,以解决导致数据泄露的潜在IT系统问题。

Contributions by individual open source software (OSS) community members are the lifeblood of the OSS projects that power today’s digital economy and are important for the very survival of such communities. Individual contributions by OSS community members to others’ projects and their own determine whether OSS communities are resilient in the face of major shocks. Arguably, if crises such as the COVID-19 pandemic prompt users to reduce their contributions to others’ projects relative to the contributions to their own projects, such behavior can have implications for the overall resilience of the OSS community. Therefore, whether and how individuals change their contributions in the face of a crisis is an important question. We examine whether members in an OSS community increased or decreased their contributions to others’ projects relative to their own in the face of the COVID-19 pandemic, a sudden and unexpected global health-related shock that has affected almost everyone. We also compare and contrast this behavior when the OSS community faced increasing unemployment, an economic cyclic shock that is arguably and relatively more personal. Drawing on the concept of prosocial behavior and conservation of resources (COR) theory, we hypothesize that the pandemic increased OSS community members’ contributions to others’ projects relative to their own; on the other hand, the threat of rising unemployment decreased OSS community members’ contributions to others’ projects relative to their own. Our empirical analyses of a longitudinal dataset of over 18,000 OSS community members on GitHub, with more than 1.4 million member-day observations, support our hypotheses. This study contributes by uncovering the differential effects of exogenous health-related and economic shocks on the resilience of the OSS community. We conclude with a discussion of our findings’ implications for OSS community resilience.
开源软件(OSS)社区成员个人的贡献是驱动当今数字经济的OSS项目的命脉,对这些社区的生存非常重要。OSS社区成员对他人项目和自己项目的个人贡献决定了OSS社区在面对重大冲击时是否具有弹性。可以说,如果像COVID-19大流行这样的危机促使用户减少对他人项目的贡献,而不是对自己项目的贡献,那么这种行为可能会对OSS社区的整体弹性产生影响。因此,面对危机,个人是否以及如何改变他们的贡献是一个重要的问题。我们研究了开源软件社区的成员在面对COVID-19大流行时,是增加还是减少了对他人项目的贡献,这是一场突如其来的全球健康冲击,几乎影响了每个人。当OSS社区面临日益增长的失业率时,我们还比较和对比了这种行为,这是一种有争议的、相对来说更个人化的经济循环冲击。根据亲社会行为和资源保护(COR)理论的概念,我们假设疫情增加了开源软件社区成员对他人项目的贡献,而不是他们自己的项目;另一方面,失业率上升的威胁减少了OSS社区成员对他人项目的贡献,而不是他们自己的项目。我们对GitHub上超过18,000名OSS社区成员的纵向数据集进行了实证分析,其中有超过140万成员日的观察结果,支持了我们的假设。这项研究的贡献在于揭示了与健康相关的外源性冲击和经济冲击对开源软件社区复原力的不同影响。最后,我们讨论了我们的发现对OSS社区弹性的影响。

Unstructured multimedia data (text and audio) provides unprecedented opportunities to derive actionable decision-making in the financial industry, in areas such as portfolio and risk management. However, due to formidable methodological challenges, the promise of business value from unstructured multimedia data has not materialized. In this study, we use a design science approach to develop DeepVoice, a novel nonverbal predictive analysis system for financial risk prediction, in the setting of quarterly earnings conference calls. DeepVoice forecasts financial risk by leveraging not only what managers say (verbal linguistic cues) but also how managers say it (vocal cues) during the earnings conference calls. The design of DeepVoice addresses several challenges associated with the analysis of nonverbal communication. We also propose a two-stage deep learning model to effectively integrate managers’ sequential vocal and verbal cues. Using a unique dataset of 6,047 earnings call samples (audio recordings and textual transcripts) of S&P 500 firms across four years, we show that DeepVoice yields remarkably lower risk forecast errors than that achieved by previous efforts. The improvement can also translate into nontrivial economic gains in options trading. The theoretical and practical implications of analyzing vocal cues are discussed.
非结构化多媒体数据(文本和音频)为金融行业在投资组合和风险管理等领域获得可操作的决策提供了前所未有的机会。然而,由于方法论上的巨大挑战,非结构化多媒体数据的商业价值前景尚未实现。在本研究中,我们使用设计科学方法开发了DeepVoice,这是一种新颖的非语言预测分析系统,用于季度收益电话会议的财务风险预测。DeepVoice预测财务风险的方法,不仅是利用经理人在财报电话会议上说的话(口头语言线索),还包括经理人说话的方式(声音线索)。DeepVoice的设计解决了与非语言交流分析相关的几个挑战。我们还提出了一个两阶段的深度学习模型,以有效地整合管理者的顺序语音和语言线索。使用标准普尔500指数公司四年来的6,047个收益电话样本(录音和文本文本)的独特数据集,我们表明DeepVoice产生的风险预测误差明显低于以前的努力。这种改善还可以转化为期权交易中可观的经济收益。讨论了分析声音线索的理论和实践意义。

Getting Trapped in Technical Debt: Sociotechnical Analysis of a Legacy System’s Replacement 陷入技术债务:遗留系统替换的社会技术分析

Organizations replace their legacy systems for technical, economic, and operational reasons. Replacement is a risky proposition, as high levels of technical and social inertia make these systems hard to withdraw. Failure to fully replace systems results in complex system architectures involving manifold hidden dependencies that carry technical debt. To understand how a process for replacing a complex legacy system unfolds and accumulates technical debt, we conducted an explanatory case study at a local manufacturing site that had struggled to replace its mission-critical legacy systems as part of the larger global company’s commercial-off-the-shelf (COTS) system implementation. We approach the replacement as a sociotechnical change and leverage the punctuated sociotechnical information system change model in combination with the design-moves framework to analyze how the site balanced creating digital options, countering social inertia, and managing (architectural) technical debt. The findings generalize to a two-level (local/global) system-dynamics model delineating how replacing a deeply entrenched mission-critical system generates positive and negative feedback loops within and between social and technical changes at local and global levels. The loops, unless addressed, accrue technical debt that hinders legacy system discontinuance and gradually locks the organization into a debt-constrained state. The model helps managers anticipate challenges that accompany replacing highly entrenched systems and formulate effective strategies to address them.
组织出于技术、经济和操作上的原因替换他们的遗留系统。替换是一个有风险的提议,因为高度的技术和社会惰性使得这些系统很难退出。如果不能完全替换系统,就会导致复杂的系统架构,其中包含许多隐藏的依赖关系,这些依赖关系带有技术债务。为了理解替换复杂遗留系统的过程是如何展开并积累技术债务的,我们在一个本地制造站点进行了一个解释性案例研究,该站点一直在努力替换其关键任务遗留系统,作为大型全球公司的商用现货(COTS)系统实现的一部分。我们将替换作为一种社会技术变化,并利用间断的社会技术信息系统变化模型与设计-移动框架相结合,分析场地如何平衡创造数字选项,对抗社会惯性和管理(建筑)技术债务。研究结果概括为一个两级(地方/全球)系统动力学模型,该模型描述了取代一个根深蒂固的关键任务系统如何在地方和全球层面的社会和技术变革内部和之间产生积极和消极的反馈循环。这些循环,除非得到解决,否则会积累技术债务,阻碍遗留系统的中断,并逐渐将组织锁定在债务约束的状态中。该模型帮助管理者预测替换高度根深蒂固的系统所带来的挑战,并制定有效的策略来应对这些挑战。

The rise of technology-enabled ride-hailing services has affected individuals’ transportation-related decisions. The impact of these ride-hailing services likely varies across traveler segments that differ in their usage of various modes of transportation. In this paper, we develop and leverage a framework that allows us to examine the impact of ride-hailing services on the transportation mode choice for three traveler segments: drivers (who primarily use a personal automobile to travel), riders (who primarily use public transit to travel), and walkers (who primarily use non-motorized modes of transport). We first develop a framework outlining how the behavior of different traveler segments would be impacted by the introduction of ride-hailing services and show how this affects traffic congestion and public transportation ridership. To test the framework, we compiled a rich dataset, combining data on public transportation ridership, traffic congestion, and individual transportation mode choice. Employing a difference-in-differences methodology, we show that the Uber entry in a market enabled those who were walkers and riders prior to the entry of Uber to travel more conveniently, leading to an increase in traffic congestion, and induced those who were drivers to substitute their use of private automobiles with a combination of Uber and public transit. We introduced urban compactness to assess the heterogeneous impact of ride-hailing services for cities that differ in their distribution of traveler segments. We found that Uber entry increases traffic congestion and reduces public transit demand more in cities with higher levels of urban compactness, i.e., where the proportion of riders and walkers is higher than that of drivers. This work provides a holistic framework to understand the mechanism underlying the impact of ride-hailing services on public transit and traffic congestion. Urban planners and policy makers can leverage our framework, methodology, and empirical results to guide city planning decisions that have implications for sustainability.
技术驱动的网约车服务的兴起影响了个人的交通相关决策。这些网约车服务的影响可能会因使用各种交通方式的不同而有所不同。在本文中,我们开发并利用了一个框架,使我们能够检查乘车服务对三个旅行者群体的交通方式选择的影响:司机(主要使用个人汽车旅行)、乘客(主要使用公共交通工具旅行)和步行者(主要使用非机动交通工具)。我们首先建立了一个框架,概述了网约车服务的引入将如何影响不同旅客群体的行为,并展示了这将如何影响交通拥堵和公共交通乘客。为了测试这个框架,我们编制了一个丰富的数据集,结合了公共交通乘客、交通拥堵和个人交通方式选择的数据。采用差异中的差异方法,我们表明优步进入市场使那些在优步进入之前是步行者和骑手的人更方便地出行,导致交通拥堵增加,并诱使那些司机用优步和公共交通的结合来代替私家车的使用。我们引入了城市紧凑性来评估网约车服务对不同旅行者分布的城市的异质影响。我们发现,在城市紧凑程度较高的城市,即乘客和步行者的比例高于司机的城市,Uber的加入更容易加剧交通拥堵,减少公共交通需求。这项工作为理解网约车服务对公共交通和交通拥堵的影响机制提供了一个整体框架。城市规划者和政策制定者可以利用我们的框架、方法和实证结果来指导对可持续性有影响的城市规划决策。
