1、金融科技的崛起:利用数字足迹进行信用评分


我们分析了数字足迹的信息内容,数字足迹就是用户通过在线访问或注册网站而留下的信息,在本文中可用于预测用户的违约风险。我们发现,即使是简单易得的数字足迹变量也能够与消费者在征信机构处得分的信息相匹配。数字足迹是对征信机构信息的补充,而非替代,它将影响信贷的获取并降低违约率。本文讨论了金融中介机构的商业模式、非银行信贷的获取以及消费者、公司和监管机构在数字领域行为的影响。


We analyze the information content of a digital footprint—that is, information that users leave online simply by accessing or registering on a Web site—for predicting consumer default. We show that even simple, easily accessible variables from a digital footprint match the information content of credit bureau scores. A digital footprint complements rather than substitutes for credit bureau information and affects access to credit and reduces default rates. We discuss the implications for financial intermediaries’ business models, access to credit for the unbanked, and the behavior of consumers, firms, and regulators in the digital sphere.

2、资产价值信息不对称或不完整?


我们建立了一个新的研究框架,并将文本信息用于实证模型的数据部分。该框架能识别非结构化文本中重要的信息,这些信息可以控制资产之间的多维异质性。此外,我们通过对房地产住宅市场中委托代理问题的检验,验证了该框架的有效性。我们发现,当包含重要的文本信息时,现有文献中报告的代理人保费会消失。因此,结果表明,前人对代理人保费的研究中存在遗漏的变量偏差,导致前人的研究错误地将其归因于与不对称信息相关的市场扭曲。


We provide a new framework for using text as data in empirical models. The framework identifies salient information in unstructured text that can control for multidimensional heterogeneity among assets. We demonstrate the efficacy of the framework by reexamining principal-agent problems in residential real estate markets. We show that the agent-owned premiums reported in the extant literature dissipate when the salient textual information is included. The results suggest the previously reported agent-owned premiums suffer from an omitted variable bias, which prior studies incorrectly ascribed to market distortions associated with asymmetric information.

3、通过纵向收购进行创新活动和整合


我们使用了与投入产出表中与产品词汇表相关的产品文本信息,以此来研究纵向收购的决定因素。我们发现,创新阶段对于理解纵向收购非常重要。研发密集型企业不太可能成为纵向收购的目标。相比之下,拥有专利创新的公司更有可能向纵向相关的买家出售产品。当潜在收购方难以提供创新激励时,企业的研发强度对其纵向收购更为重要。当潜在买家面临更高的拒付风险时,专利在促进纵向收购方面的作用则更为普遍。


We examine the determinants of vertical acquisitions using product text linked to product vocabulary from input-output tables. We find that the innovation stage is important in understanding vertical integration. R&D-intensive firms are less likely to become targets of vertical acquisitions. In contrast, firms with patented innovation are more likely to sell to vertically related buyers. Firms’ R&D intensity is a more important deterrent to their vertical acquisitions when the provision of innovation incentives by potential acquirers is more difficult. The role of patents in fostering vertical acquisitions is more prevalent when potential buyers face a higher risk of holdup.

4、CEO对不确定性态度的文化根源:来自企业收购的证据


我们在企业收购决策的背景下,研究了文化遗产在塑造美国CEO对待不确定性的态度方面所起的作用。我们发现,厌恶文化遗产不确定性的首席执行官更不可能参与收购。再者,我们以进行收购为条件,厌恶不确定性的CEO倾向于选择熟知的行业和更容易收购的对象。此外,CEO父母对文化认同的重视以及CEO早期生活环境的民族构成对文化传播过程有显著影响。关于不确定性态度的文化差异持续了好几代人,但随着时间的推移变得不那么明显。


We examine the role of cultural heritage in shaping U.S. CEOs’ attitudes toward uncertainty, in the context of their corporate acquisition decisions. We find that CEOs with a more uncertainty-avoiding cultural heritage are less likely to engage in acquisitions. Conditional on making an acquisition, uncertainty-averse CEOs prefer targets in familiar industries and targets that can be more easily integrated. The emphasis on cultural identity by CEOs’ parents and the ethnic composition of CEOs’ early life environment significantly influence the cultural transmission process. Cultural differences about uncertainty attitudes persist over multiple generations, but become less pronounced over time.

5、政治、国有制和企业投资


我们将印度宪法规定的选举日程作为政客迎合选民动机的外生变量,记录了国有企业投资决策的政治周期。本文利用项目级投资数据库,发现国有企业在选举年以及邻近选举地点、高级政治家和左翼现任者的地区,会公布更多的资本支出项目,尤其是在基础设施方面。在选举年,国有企业项目的公告回报率为负,表明股东价值下降。这些现象在非国有企业或非选举年份都不常见。


We document a political cycle in the investment decisions of state-owned enterprises (SOEs) by using the constitutionally mandated election schedule in India as a source of exogenous variation in politicians’ incentive to cater to voters. Using a project-level investment database, we find that SOEs announce more capital expenditure projects in election years, especially in infrastructure, and in districts with close elections, high-ranking politicians, and left-wing incumbents. SOE projects in election years have negative announcement returns, suggesting a loss in shareholder value. These patterns are not seen in nongovernment firms or in off-election years.

6、国有企业政治投资周期


本研究以超14万家国有企业为研究对象,考察了2001年至2015年期间,欧洲25个国家的82次全国大选前后国有企业的投资行为。我们发现,在全国大选期间,国有企业增加的企业投资约为样本平均水平的29%。这种影响在一定时间内和竞争激烈的选举中更为明显。在制度质量较低、政治制度较为集中、银行体系由国家控制的国家,这种影响也更为强烈。相比之下,我们发现在全国大选期间,对应的非国有企业显著减少了他们的企业投资。


Using a large panel of more than 140,000 state-owned enterprises (SOEs), this study examines SOEs’ investment behavior surrounding 82 national elections in 25 European countries between 2001 and 2015. We find that SOEs increase their corporate investment by about 29% of the sample average during national election years. This effect is more pronounced in fixed timing and closely contested elections. The effect is also stronger in countries with low institutional quality, more centralized political systems, and state-controlled banking systems. In contrast, we find the matched non-SOEs significantly decrease their corporate investment during national election years.

7、股东治理与CEO薪酬:薪酬话语权的同伴效应


本文的研究表明,薪酬同行在薪酬投票上的发言权较弱的公司,在薪酬投票后会降低CEO的薪酬。减薪反映了代理顾问对同行薪酬合同的担忧,当CEO获得超额薪酬、在高管劳动力市场上与投票权较弱的同行竞争更激烈、以及同行表现良好时,减薪幅度会更大。在同行公布修订后的薪酬后,CEO薪酬就会减少,这与公司在同行群体中保持相对职位所需的薪酬成比例。因此,我们的结论是,股东投票的溢出效应是通过学习渠道和薪酬目标渠道实现的。


We document that firms whose compensation peers experience weak say on pay votes reduce CEO compensation following those votes. Reductions reflect proxy adviser concerns about peers’ compensation contracts and are stronger when CEOs receive excess compensation, when they compete more closely with their weak-vote peers in the executive labor market, and when those peers perform well. Reductions occur following peers’ disclosures of revised pay and are proportional to those needed to retain firms’ relative positions in their peer groups. We conclude that the spillover effects of shareholder voting occur through both learning and compensation targeting channels.

8、运气报酬的对称性


在这项研究中,我们全面地考察了运气报酬的不对称性,也就是说,CEO因运气好而得到奖励,但运气差而受到惩罚的程度有所不同。基于200多条不同的样本,我们的主要结论是,运气报酬方面不存在不对称性,即是对称的。本文的结论十分重要,因为以往文献中广泛认同运气报酬不对称的观点,并将其作为抽租的证据。


In this study, we take a comprehensive look at asymmetry in pay for luck, which is the finding that CEOs are rewarded for good luck, but are not penalized to the same extent for bad luck. Our main takeaway, which is based on over 200 different specifications, is that there is no asymmetry in pay for luck. Our finding is important given that the literature widely accepts the idea of asymmetry in pay for luck and typically points to this as evidence of rent extraction.

9、为什么IPO会影响竞争对手?


IPO公司的竞争对手在IPO公司IPO后往往会出现业绩下滑的现象。究其原因,我们估计了一个动态结构的寡头垄断模型,以区分用以解释IPO后行业演变的替代性理论。我们发现,竞争对手业绩的大部分变化都是由于行业趋势导致的,这些趋势也推动了IPO的上市。然而,我们也发现了一些“竞争性”IPO,即IPO公司以竞争对手为代价来提高自身公司的绩效。这些发现有助于调和先前关于IPO公司及其竞争对手平均业绩都下降的案例,以及公司从上市中受益的典型案例。


IPO firms’ rivals tend to experience performance declines following an IPO in the industry. Why? We estimate a dynamic structural oligopoly model to distinguish between alternative theories that can explain an industry’s evolution post-IPO. We find that most changes in rivals’ performance are due to industry trends that also drive IPOs. However, we also find some “competitive” IPOs where the IPO enhances the IPO firm’s performance at the expense of competitors. These findings help reconcile prior evidence of average performance reductions of both IPO firms and their rivals with well-known cases in which firms have benefited from going public.

10、实物期权行权:经验证据


我们研究了公司何时以及为什么行使实物期权。基于详细的项目级投资数据,我们发现公司行使实物期权的可能性与同行行权行为密切相关。同行行权决策在解释行权行为时与通常与标准实物期权理论(如波动率)相关的变量一样重要。我们在同行项目行权决策中使用局部外生变量来识别同伴效应,并发现与信息外部性相一致的信息对行权行为很重要。


We study when and why firms exercise real options. Using detailed project-level investment data, we find that the likelihood that a firm exercises a real option is strongly related to peer exercise behavior. Peer exercise decisions are as important in explaining exercise behavior as variables commonly associated with standard real option theories, such as volatility. We identify peer effects using localized exogenous variation in peer project exercise decisions and find evidence consistent with information externalities being important for exercise behavior.

11、绿色能源的价值:互斥项目的最优投资和运营杠杆


我们研究了具有不同成本结构的独家项目的投资。我们的分析包含两种路径,即从两种可选技术中分别产生随机可变成本和固定成本的随机收入流的可能性,并考虑了项目经理的内生运营决策的作用。本文发现最优投资决策具有两个可能非单调边界。我们还研究了营运杠杆对管理政策、投资决策和价值的影响,并将其应用于发电项目。最后我们还评估了知识获取对投资的影响,即对可持续性的投资。
