I demonstrate that, on average, information asymmetry grows between earnings announcements and falls right after each new earnings announcement. I estimate that percent effective spreads typically grow 3.1% over the course of the inter-announcement period. I demonstrate that this inter-announcement growth in information asymmetry occurs gradually throughout the entire inter-announcement period and not just right before each new earnings announcement. This inter-announcement growth has implications for reporting frequency decisions. A semiannual reporter that switches to quarterly reporting cuts the growth time in half by cutting each semiannual reporting period into two quarterly reporting periods. As a result, it reduces information asymmetry in what would have been the second half of the semiannual reporting period. I confirm this in a European setting, showing that the average reduction in bid-ask spreads from the inter-announcement growth channel is 1.6% when firms switch from semiannual to quarterly reporting.

我证明,平均而言,信息不对称在业绩公告之间增长,并在每次新的业绩公告之后下降。我估计,在公告发布期间,有效利差通常会增长3.1%。我证明了这种公告间信息不对称的增长在整个公告期间逐渐发生,而不仅仅是在每次新的收益公告之前。这种公告间的增长对报告频率的决定有影响。半年报告改为季度报告,将每个半年报告周期缩短为两个季度报告周期,从而将增长时间缩短一半。因此,它减少了半年报告期下半年的信息不对称。我在欧洲的环境中证实了这一点,表明当公司从半年报告转为季度报告时,从公告间增长渠道的买卖价差平均减少了1.6%。这篇论文被会计Suraj Srinivasan接受。

Comment on "Modeling Purchasing Behavior with Sudden 'Death': A Flexible Customer Lifetime Model" 评《以突然“死亡”为购买行为建模:一个灵活的顾客生命周期模型》

Jost Adler
In their 2012 paper, Bemmaor and Glady introduced the gamma/Gompertz/negative binomial distribution model for customer base analysis. Their model uses exponentially distributed interpurchase times and a Gompertz distributed customer lifetime, where the latter distribution is nonmemoryless. This comment corrects an error in their expression for the conditional expected number of individual future purchases [Formula: see text] in a forecasting interval of length [Formula: see text]. Contrary to their approach, the correct derivation of the conditional expectation must be based on the conditional survival and density functions of the lifetime distribution. Using the wrong formula leads managers to overestimate the expected future customer purchases. Further, the comment corrects the erroneous expressions for the conditional variance [Formula: see text] and the conditional mean residual lifetime [Formula: see text]. This paper was accepted by Raphael Thomadsen, marketing.
在2012年的论文中,Bemmaor和Glady引入了用于客户群分析的gamma/Gompertz/负二项分布模型。他们的模型使用指数分布的互购时间和Gompertz分布的客户生命周期,后者的分布是非无内存的。这个注释纠正了他们在长度[公式:见文本]的预测区间中对个人未来购买的条件预期数量[公式:见文本]的表达式中的错误。与他们的方法相反,条件期望的正确推导必须基于寿命分布的条件生存和密度函数。使用错误的公式会导致管理者高估未来顾客的购买量。此外,注释更正了条件方差[公式:见文本]和条件平均剩余寿命[公式:见文本]的错误表达式。这篇论文被市场营销学的Raphael Thomadsen接受。

The decision usefulness of the direct versus indirect presentation method of a cash flow statement has been a long-standing issue in both practice and accounting research. By capitalizing on comparative advantages of experimental methods, we provide insights into how investors process the information contained in different presentation methods to make cash flow forecasts, especially in the context of various types of nonrecurring items. We predict and find that, when nonrecurring accrued expenses are present, the indirect method leads to lower forecast errors by activating investors’ underlying knowledge structures of operating cash flows in terms of an accrual (versus cash) basis. We also find that, in the presence of nonrecurring cash or nonrecurring accrued revenues, there is no difference in forecast errors between the indirect and direct methods. Moreover, we find that the combination of the direct and indirect methods (the direct-plus-indirect method) leads to lower forecast errors than the direct method, but it does not provide an incremental benefit for forecast accuracy beyond the indirect method.

现金流量表直接列报法与间接列报法的决策有用性在实务和会计研究中一直是一个长期存在的问题。通过利用实验方法的比较优势,我们提供了投资者如何处理不同列报方法中包含的信息以进行现金流量预测的见解,特别是在各种类型的非经常性项目的背景下。我们预测并发现,当非经常性应计费用存在时,间接方法通过激活投资者在应计制(相对于现金)基础上的经营性现金流量的潜在知识结构,导致较低的预测误差。我们还发现,在存在非经常性现金或非经常性应计收入的情况下,间接法和直接法的预测误差没有差异。此外,我们发现直接和间接方法相结合(直接加间接方法)导致预测误差低于直接方法,但没有提供超过间接方法的预测精度增量效益。这篇论文被会计Brian Bushee接受。

Analyzing Active Fund Managers' Commitment to ESG: Evidence from the United Nations Principles for Responsible Investment 分析主动型基金经理对ESG的承诺:来自联合国负责任投资原则的证据
Pub Date : 2022-04-18 DOI: 10.1287/mnsc.2022.4394
Soohun Kim, Aaron S. Yoon
The United Nations Principles for Responsible Investment (PRI) is the largest global environmental, social, and governance (ESG) initiative in the asset-management industry to date. We analyze what happens after active U.S. mutual funds sign the PRI to assess whether they exhibit ESG implementation. We find that PRI signatories attract a large fund inflow, but we do not observe improvements in fund-level ESG scores or fund returns. We consider a battery of ways to proxy for funds’ ESG incorporation (e.g., entry/exit, screening, engagement, voting for pro-ESG proposals), but fail to observe evidence of meaningful on average follow-through. Next, we explore cross-sectional fund characteristics and find that only quant funds exhibit small improvements in ESG performance versus other funds, mainly through buying high-ESG-performing stocks. Furthermore, we note that signatories are not superior performers in ESG issues prior to joining the PRI relative to non-PRI funds, but PRI affiliation tends to be widely advertised on company websites, marketing materials, and fund documents. Overall, a reasonable reader may perceive our findings as consistent with PRI funds’ greenwashing. We note, however, that what we uncover is based only on outcome-based measures and may miss some actual efforts of signatories. This paper was accepted by Brian Bushee, accounting.
联合国负责任投资原则(PRI)是迄今为止资产管理行业最大的全球环境、社会和治理(ESG)倡议。我们分析了活跃的美国共同基金签署PRI后的情况,以评估它们是否表现出ESG实施情况。我们发现,PRI签署国吸引了大量资金流入,但我们没有观察到基金层面ESG得分或基金回报的改善。我们考虑了一系列代理基金加入ESG的方法(例如,加入/退出、筛选、参与、对支持ESG的提案投票),但未能观察到有意义的平均后续行动的证据。接下来,我们探讨了基金的横截面特征,发现只有量化基金在ESG绩效方面比其他基金有小幅改善,主要是通过购买ESG表现良好的股票。此外,我们注意到,在加入PRI之前,签约方在ESG问题上的表现并不比非PRI基金好,但PRI关系往往在公司网站、营销材料和基金文件上被广泛宣传。总的来说,一个理性的读者可能会认为我们的发现与PRI基金的绿色清洗是一致的。然而,我们注意到,我们所发现的只是基于结果的衡量标准,可能会错过签署国的一些实际努力。这篇论文被会计Brian Bushee接受。

Two-Sided Platform Competition in a Sharing Economy 共享经济中的双边平台竞争
Pub Date : 2022-04-18 DOI: 10.1287/mnsc.2022.4302
Chenglong Zhang, Jianqing Chen, Srinivasan Raghunathan
We examine competition between two-sided platforms in a sharing economy. In sharing economies, workers self-schedule their supply based on the wage they receive. The platforms compete for workers as well as consumers. To attract workers, platforms use diverse wage schemes, including fixed commission rate, dynamic commission rate, and fixed wage. We develop a model to examine the impacts of the self-scheduled nature of the supply on competing platforms and the role of the wage scheme in the platform competition. We find that the price competition between platforms is more intense in a sharing economy compared with an economy with a fixed supply of workers if and only if the platforms serve more consumers and workers in the sharing economy than in the traditional economy, regardless of the wage scheme employed by the platforms. Further, any of the three wage schemes can be the best for the platforms and the worst for consumers and workers, depending on the market characteristics. In markets where the competition is more fierce on the demand side than on the supply side, the fixed-wage scheme results in the highest profits for the platforms and lowest surpluses for consumers and workers. In contrast, in markets where the competition on the supply side is more competitive, when the supply is highly (mildly) more competitive, the fixed-commission-rate (dynamic-commission-rate) scheme generates the highest profits for platforms, leading to the lowest surpluses for consumers and workers and the lowest social welfare. The differential impacts of the wage scheme on the price (demand side) and quantity (supply side) competition explain our findings. This paper was accepted by Kartik Hosanagar, information systems.
我们研究了共享经济中双边平台之间的竞争。在共享经济中,工人根据他们收到的工资自行安排供应。这些平台在争夺员工的同时也在争夺消费者。为了吸引工人,平台采用了多种工资方案,包括固定佣金率、动态佣金率和固定工资。我们开发了一个模型来检验供应的自我安排性质对竞争平台的影响以及工资计划在平台竞争中的作用。我们发现,在共享经济中,平台之间的价格竞争比固定劳动力供给的经济更加激烈,当且仅当平台在共享经济中服务的消费者和工人比传统经济中更多,而不管平台采用的工资方案如何。此外,根据市场特点,这三种工资方案中的任何一种都可能对平台来说是最好的,对消费者和工人来说是最差的。在需求侧竞争比供给侧竞争更激烈的市场中,固定工资方案导致平台的利润最高,而消费者和工人的剩余最低。相反,在供给方竞争更激烈的市场中,当供给方竞争高度(轻度)更激烈时,固定佣金率(动态佣金率)方案为平台产生最高的利润,导致消费者和工人的剩余最低,社会福利最低。工资方案对价格(需求方)和数量(供给方)竞争的不同影响解释了我们的发现。这篇论文被Kartik Hosanagar,信息系统所接受。

Although leveraged exchange-traded funds (ETFs) are popular products for retail investors, how to hedge them poses a great challenge to financial institutions. We develop an optimal rebalancing (hedging) model for leveraged ETFs in a comprehensive setting, including overnight market closure and market frictions. The model allows for an analytical optimal rebalancing strategy. The result extends the principle of “aiming in front of target” introduced by Gârleanu and Pedersen (2013) from a constant weight between current and future positions to a time-varying weight because the rebalancing performance is monitored only at discrete time points, but the rebalancing takes place continuously. Empirical findings and implications for the weekend effect and the intraday trading volume are also presented. This paper was accepted by Agostino Capponi, finance.
虽然杠杆型交易所交易基金(etf)是深受散户投资者欢迎的产品,但如何对其进行对冲对金融机构来说是一个巨大的挑战。我们为杠杆etf开发了一个综合设置的最佳再平衡(对冲)模型,包括隔夜市场关闭和市场摩擦。该模型允许分析最佳再平衡策略。该结果将g rleanu和Pedersen(2013)引入的“瞄准目标前”原则从当前和未来位置之间的恒定权重扩展到时变权重,因为再平衡性能仅在离散时间点进行监控,但再平衡是连续进行的。实证结果和启示的周末效应和日内交易量也提出。这篇论文被金融学的阿戈斯蒂诺·卡波尼接受。

We extend the existing literature on gender differences in competitive behavior by investigating tournament entry choices when a principal decides for an agent. In a laboratory experiment, we randomly assign subjects the role of either principal or agent. The principal decides whether the agent performs a real-effort task under piece-rate or tournament incentives. When deciding, the principal is informed about the agent’s previous performance, age, and residency. Between treatments, we vary whether the principal knows the agent’s gender. In a baseline treatment, we replicate the standard setting in which subjects decide for themselves whether to compete. Our main findings are, first, that there is no gender gap in tournament entry when principals decide for agents as opposed to the baseline treatment. Second, the gender gap closes because more women are made to compete by principals. Third, whereas there is no gender gap in either of the principal treatments, revealing the agent’s gender is associated with higher overall tournament entry rates. Exploratory analyses of principals’ choice determinants reveal a positive effect of preferences to take risks, competitiveness, and confidence in agents’ performances on making agents compete. In addition, we find no difference in how principals evaluate male and female agents’ performances. Finally, we test the efficiency of principals’ competition choices and show that they lead to fewer payoff-maximizing outcomes than when subjects decide for themselves. Additionally, overall tournament performances and winners’ performances are lower when agents are made to compete, but this effect is not robust to controlling for agents’ previous performances. This paper was accepted by Yan Chen, behavioral economics and decision analysis.
我们扩展了已有的关于竞争行为的性别差异的文献,通过调查当委托人决定代理人时的比赛进入选择。在实验室实验中,我们随机分配受试者扮演委托人或代理人的角色。委托人决定代理人是在计件工资激励下还是在比赛激励下执行真正努力的任务。在做决定时,委托人会被告知代理人以前的业绩、年龄和居住地。在治疗之间,我们对委托人是否知道代理人的性别有所不同。在基线治疗中,我们复制了受试者自行决定是否竞争的标准设置。我们的主要发现是,首先,当委托人决定代理而不是基线处理时,参加比赛没有性别差异。其次,性别差距缩小了,因为更多的女性被校长要求参加竞争。第三,尽管在两种主要处理方法中都没有性别差异,但这表明经纪人的性别与更高的整体参赛率有关。对委托人选择决定因素的探索性分析揭示了风险偏好、竞争力和对代理人绩效的信心对代理人竞争的积极影响。此外,我们发现委托人对男性和女性代理人绩效的评价没有差异。最后,我们测试了委托人竞争选择的效率,并表明他们导致的收益最大化结果少于受试者自己决定的结果。此外,当代理人被要求参加比赛时,总体比赛表现和获胜者的表现都较低,但这种影响在控制代理人之前的表现时并不稳健。本文被闫晨、行为经济学和决策分析等学科接受。

Female Directors and Firm Value: New Evidence from Directors' Deaths 女性董事与公司价值:来自董事死亡的新证据
Pub Date : 2022-04-11 DOI: 10.1287/mnsc.2022.4412
Thomas Schmid, Daniel Urban
This paper examines how female directors (FDs) affect firm value in the absence of mandatory gender quotas. Using a newly collected data set on director deaths around the globe, we find that stock prices decrease approximately 2% more when an FD passes away, compared with a male director. What explains this negative capital market reaction? We find evidence that finding successors for deceased FDs is challenging for firms: Succession delays are longer, and although firms try to replace FDs with women, two-thirds of their successors are male. Furthermore, their successors tend to be younger, less experienced, and more often externally hired. Stock prices decline less if more potential female successors exist in a country, the firm is larger, or FDs other than the deceased woman were on the board. Because observable characteristics such as age, tenure, education, and network centrality cannot explain the negative stock market reaction, unobserved differences across genders that lead to a lower fit of male successors to the existing board are the most likely explanation for the firm value loss after the death of an FD.

本文研究了在没有强制性性别配额的情况下,女性董事如何影响公司价值。使用最新收集的全球董事死亡数据集,我们发现,与男性董事相比,当男性董事去世时,股价下跌约2%。如何解释资本市场的这种负面反应?我们发现有证据表明,为已故的董事寻找继任者对公司来说是一项挑战:继任延迟更长,尽管公司试图用女性替换董事,但三分之二的继任者是男性。此外,他们的继任者往往更年轻,经验不足,而且往往是从外部招聘的。如果一个国家有更多潜在的女性接班人,公司规模更大,或者董事会中有已故女性以外的董事,那么股价的跌幅就会较小。由于年龄、任期、教育程度和网络中心等可观察到的特征无法解释股市的负面反应,因此未观察到的性别差异导致现有董事会的男性继任者更不合适,这是最可能解释公司价值损失的原因。这篇论文被David Simchi-Levi接受。

Using a newly collected data set on director deaths around the globe, we find that stock prices decrease approximately 2% more when an FD passes away, compared with a male director. What explains this negative capital market reaction? We find evidence that finding successors for deceased FDs is challenging for firms: Succession delays are longer, and although firms try to replace FDs with women, two-thirds of their successors are male. Furthermore, their successors tend to be younger, less experienced, and more often externally hired. Stock prices decline less if more potential female successors exist in a country, the firm is larger, or FDs other than the deceased woman were on the board. Because observable characteristics such as age, tenure, education, and network centrality cannot explain the negative stock market reaction, unobserved differences across genders that lead to a lower fit of male successors to the existing board are the most likely explanation for the firm value loss after the death of an FD.

Mismarking in Mutual Funds 共同基金的失误
Pub Date : 2022-04-11 DOI: 10.1287/mnsc.2022.4366
V. Atanasov, John J. Merrick, Philipp Schuster
We study mismarking of newly purchased odd lot and two classes of round lot structured product positions in mutual funds. Such mismarking artificially inflates net asset values and overstates cumulative returns. Applied to funds launched after January 2010, a simulation-tested mismarking fund filter identifies 12 Highly Questionable funds managing $75 billion. The performance of these funds matches closely the predicted pattern of mismarking: extremely high alpha and skewness, particularly immediately after launch. We show that structured product mismarking can seriously inflate return-since-inception metrics. We also provide evidence consistent with return smoothing for one quarter of the sample structured product funds. The inflated performance metrics benefit fund managers through significantly higher Sharpe ratios, Morningstar ratings, and asset growth but cause material losses to later investor cohorts.

研究了共同基金中新买入的奇数手和两类圆手结构性产品头寸的错标问题。这种错误标记人为地夸大了资产净值,夸大了累计回报。应用于2010年1月以后成立的基金,一个经过模拟测试的错误标记基金过滤器识别出12只高度可疑的基金,管理着750亿美元。这些基金的表现与预测的错标模式非常吻合:极高的alpha值和偏度,尤其是在刚推出后。我们表明,结构化产品的错误标记会严重夸大自开始以来的回报指标。我们还提供了与四分之一样本结构性产品基金的收益平滑一致的证据。夸大的业绩指标通过显著提高夏普比率、晨星评级和资产增长,使基金经理受益,但对后来的投资者群体造成重大损失。这篇论文被金融学的阿戈斯蒂诺·卡波尼接受。

Firm-Induced Migration Paths and Strategic Human-Capital Outcomes 企业诱导的迁移路径与战略性人力资本成果
Pub Date : 2022-04-07 DOI: 10.1287/mnsc.2022.4361

Firm-induced migration typically entails firms relocating workers to fill value-creating positions at destination locations. But such relocated workers are often exposed to external employment opportunities at their destinations, possibly triggering turnover. We conceptualize the firm-induced migration path, consisting of the relocated workers’ place of origin and destination, as relevant in determining worker performance and turnover postrelocation. Using a unique data set from a large Indian technology firm that hires talent from both large cities and smaller towns, we document robust econometric patterns by exploiting the firm’s randomized assignment of workers to production centers across the country. These production centers are located in the largest technology cluster in India (Bangalore), smaller technology clusters, and noncluster locations. We find that the firm-induced migration path shapes both worker performance and turnover. Compared with workers from large cities, workers from smaller towns achieve higher performance when relocated to Bangalore than to other production centers, but are also more likely to join competing firms. Fine-grained data on employment and human-capital-augmentation opportunities at workers’ destination locations, and on socioeconomic conditions in workers’ places of origin, help us rule in an abductive explanation: across firm-induced migration paths, differences in external labor-market opportunities between workers’ places of origin and their destinations, as well as intrafirm skill-development opportunities at the destination, are related to heterogeneous human-capital outcomes.

企业诱导的迁移通常需要企业重新安置工人,以填补目的地创造价值的职位。但这些被重新安置的工人往往会在他们的目的地面临外部就业机会,这可能会引发人员流动。我们将企业诱导的迁移路径概念化,包括搬迁工人的原籍地和目的地,这与决定工人的绩效和迁移后的流动率有关。使用来自印度一家大型科技公司的独特数据集,该公司从大城市和小城镇招聘人才,我们通过利用该公司将工人随机分配到全国各地的生产中心,记录了稳健的计量经济模式。这些生产中心位于印度最大的技术集群(班加罗尔)、较小的技术集群和非集群地点。我们发现,企业诱导的迁移路径既影响了员工绩效,也影响了员工流动率。与来自大城市的工人相比,从小城镇搬到班加罗尔的工人比搬到其他生产中心的工人表现更好,但也更有可能加入竞争对手的公司。关于工人原籍地就业和人力资本增加机会以及工人原籍地社会经济状况的细粒度数据,帮助我们得出了一个溯因性的解释:在企业诱导的迁移路径中,工人原籍地和目的地之间外部劳动力市场机会的差异,以及目的地企业内部技能发展机会的差异,都与异质性人力资本结果有关。这篇论文被商业战略家Alfonso Gambardella接受。
