1、全球公司控制权


我们研究了2004-2012年间127个国家数千家上市公司的控制权追踪。政府和家庭控制在大陆法系国家普遍存在,并且十分常见,但在普通法系国家(英美法系国家)则不太常见。这些模式适用于大、中、小公司。相比之下,开发控制的关系是异质的;对大公司来说很重要,但对小公司来说却少见。控制权与股东保护、雇佣合同的严格性及工会权力密切相关。相反,与债权人权利、法律形式主义和进入管制的相关性似乎很弱。这些模式既支持金融发展的法律渊源,也支持金融发展的政治理论。


We study corporate control tracing controlling shareholders for thousands of listed firms from 127 countries over 2004 to 2012. Government and family control is pervasive in civil‐law countries. Blocks are commonplace, but less so in common‐law countries. These patterns apply to large, medium, and small firms. In contrast, the development‐control nexus is heterogeneous; strong for large but absent for small firms. Control correlates strongly with shareholder protection, the stringency of employment contracts and unions power. Conversely, the correlations with creditor rights, legal formalism, and entry regulation appear weak. These patterns support both legal origin and political theories of financial development.

2、失业保险能刺激创业活动吗?来自法国的证据


我们评估了下行经济的保险对自营雇佣工作的影响。法国大规模改革后的失业福利为失业工人提供了创业的保险。改革在不降低新创业者素质的前提下,显著增加了企业的创造力。改革后开始的公司最初规模较小,但它们的就业增长、生产率和生存率与改革前相似,新企业家的特点和前景也十分相似。最后,新创业者创造的就业机会几乎是一对一地挤占了现有企业的就业机会,但其生产率高于现有企业。这些现象突出了降低进入壁垒来鼓励创业的优势所在。


We evaluate the effect of downside insurance on self‐employment. We exploit a large‐scale reform of French unemployment benefits that insured unemployed workers starting businesses. The reform significantly increased firm creation without decreasing the quality of new entrants. Firms started postreform were initially smaller, but their employment growth, productivity, and survival rates are similar to those prereform. New entrepreneurs' characteristics and expectations are also similar. Finally, jobs created by new entrants crowd out employment in incumbent firms almost one‐for‐one, but have a higher productivity than incumbents. These results highlight the benefits of encouraging experimentation by lowering barriers to entry.

3、钻井与债务


本文记录了一个被前人忽略的与债务相关的投资曲解。通过对69家石油和天然气行业公司的详细项目级数据进行分析,我们发现高杠杆公司会提前投资,并以牺牲长期项目回报和项目价值为代价提前完成项目,这种行为在债务重新谈判之前尤为明显。我们验证了几个可以解释这种行为的渠道,并找到了与股权持有人牺牲长期项目回报以提高抵押品价值相一致的证据,进而在债务重新谈判中缓解贷款摩擦。


This paper documents a previously unrecognized debt‐related investment distortion. Using detailed project‐level data for 69 firms in the oil and gas industry, we find that highly levered firms pull forward investment, completing projects early at the expense of long‐run project returns and project value. This behavior is particularly pronounced prior to debt renegotiations. We test several channels that could explain this behavior and find evidence consistent with equity holders sacrificing long‐run project returns to enhance collateral values and, by extension, mitigate lending frictions at debt renegotiations.

4、驯服因子动物园:新因子的试验


我们提出一种模型选择方法,能够系统地评估任一新因子对资产定价的贡献,远远现有高维因子集的解释能力。我们的方法解释了模型选择的错误,这些错误源于遗漏变量而产生的偏差,与标准方法假设完美的变量选择不同。我们将我们的方法应用于最近在文献中发现的一组因子。虽然这些新因子中的大多数相对于现有因子来说是多余的,但有少数因子在统计学上具有显著的解释能力,大于以往提出的数百个因子。


We propose a model selection method to systematically evaluate the contribution to asset pricing of any new factor, above and beyond what a high‐dimensional set of existing factors explains. Our methodology accounts for model selection mistakes that produce a bias due to omitted variables, unlike standard approaches that assume perfect variable selection. We apply our procedure to a set of factors recently discovered in the literature. While most of these new factors are shown to be redundant relative to the existing factors, a few have statistically significant explanatory power beyond the hundreds of factors proposed in the past.

5、滞后的价格


通过研究历史上所有的美国上市企业披露的季报和年报,作者发现财务报告语言和结构的变化对公司未来的回报和运营具有重大影响。作者通过构建做空“财报不变的企业”和做多“财报改变的企业”的投资组合,发现可获得每月高达188个基点(每年超22%)的收益。此外,年报(10-K)的变化可以预测企业未来的收益、盈利能力、未来的新闻公告,甚至是未来企业是否面临破产。然而与典型的反应不足模式不同,作者没有发现公告效应,这表明投资者不太注意上市公司这些简单的变化。


Using the complete history of regular quarterly and annual filings by U.S. corporations, we show that changes to the language and construction of financial reports have strong implications for firms’ future returns and operations. A portfolio that shorts “changers” and buys “nonchangers” earns up to 188 basis points per month in alpha (over 22% per year) in the future. Moreover, changes to 10‐Ks predict future earnings, profitability, future news announcements, and even future firm‐level bankruptcies. Unlike typical underreaction patterns, we find no announcement effect, suggesting that investors are inattentive to these simple changes across the universe of public firms.

6、是什么驱使了异常收益?


我们将五个熟知的异常收益分解为现金流和折现率信息。在五因素投资组合及其均值-方差有效(MVE)组合中出现了共同模式。当贴现率新闻在市场收益中占主导地位时,系统性现金流信息驱动异常投资组合的回报率及其与市场投资组合的MVE组合。异常现金流和贴现率冲击与市场现金流和贴现率冲击以及商业周期波动基本无关。这些丰富的经验模式限制了公司现金流和定价核心的联合动态,从而为股票的预期收益模型提供了额外信息。


We decompose the returns of five well‐known anomalies into cash flow and discount rate news. Common patterns emerge across the five factor portfolios and their mean‐variance efficient (MVE) combination. Whereas discount rate news predominates in market returns, systematic cash flow news drives the returns of anomaly portfolios and their MVE combination with the market portfolio. Anomaly cash flow and discount rate shocks are largely uncorrelated with market cash flow and discount rate shocks and with business cycle fluctuations. These rich empirical patterns restrict the joint dynamics of firm cash flows and the pricing kernel, thereby informing models of stocks' expected returns.

7、递归效用存在性及唯一性的充要条件


本文得到了由Epstein和Zin假设的一类同态递归效用模型中解的存在性及唯一性的充要条件。这个条件以一个具有自然经济解释的单一测试值为中心,该测试揭示了现金流估值、不耐、风险调整和消费跨期替代之间的关系。此外,我们还提出了两种方法来计算当解析解不可用时的测试值,最后提出了几个应用。


We obtain exact necessary and sufficient conditions for existence and uniqueness of solutions of a class of homothetic recursive utility models postulated by Epstein and Zin. The conditions center on a single test value with a natural economic interpretation. The test sheds light on the relationship between valuation of cash flows, impatience, risk adjustment, and intertemporal substitution of consumption. We propose two methods to compute the test value when an analytical solution is not available. We further provide several applications.

8、高频交易与市场表现


我们通过流动性和信息产出之间的权衡来研究高频交易(HFT)产生的后果和潜在的政策反应。我们发现更快的速度促进了高频交易,并同时对这种交易产生了影响:由于知情交易者在高频交易做出反应之前没有足够的时间进行交易,因此信息产出减少,但流动性(通过买卖价差衡量)因信息不对称性下降而得到改善。高频交易还促使了结果达到这种权衡的前沿。然而,可以通过用两种替代机制之一替换限制订单本,将结果恢复至权衡前沿:推迟除了所取消的订单外的所有订单或实施高频的批量交易


We study the consequences of, and potential policy responses to, high‐frequency trading (HFT) via the tradeoff between liquidity and information production. Faster speeds facilitate HFT, with consequences for this tradeoff: Information production decreases because informed traders have less time to trade before HFTs react, but liquidity (measured by the bid‐ask spread) improves because informational asymmetries decline. HFT also pushes outcomes inside the frontier of this tradeoff. However, outcomes can be restored to the frontier by replacing the limit order book with one of two alternative mechanisms: delaying all orders except cancellations or implementing frequent batch auctions.

9、IPO后的风险:风险投资机构为新上市公司融资


与传统观点相反,我们记录了大约15%的风险投资机构(VC)支持的公司在上市后的五年内从风投公司筹集额外资本。我们对公司在IPO(首次公开募股)后回归风投融资的原因做出了两个解释。首先,我们假设风险投资参与IPO后融资能够有效解决信息问题,否则会限制企业投资增值的能力。其次,本文对公司和风投特征的分析,发现这些投资对风投公司和IPO公司都产生了增值,支持了这一假设。最后,目前尚无根据表示代理冲突能够激励这些投资的替代方案。


Contrary to conventional wisdom, we document that approximately 15% of venture capitalist (VC)‐backed firms raise additional capital from VCs in the five years after going public. We propose two explanations for why firms revert to VC financing post‐IPO (initial public offering). First, we hypothesize that VC participation in post‐IPO financing represents an efficient solution to informational problems that would otherwise constrain firms’ abilities to exploit value‐increasing investments. Analyses of firm and VC characteristics, together with the finding that these investments are value‐increasing for both VCs and the underlying companies, support this hypothesis. We find no support for the alternative that agency conflicts motivate these investments.

10、内幕投资期限


我们研究了内幕人士的投资期限与他们交易的信息含量与未来股票收益的关系。我们推测,内幕人士的投资期限为预期的持续交易行为模式建立了一个基准,从而有助于识别意料外的内幕交易,这在有效市场中应该更具信息量。与这一推测相一致,我们发现平均而言,短期内幕人士比长期内幕人士的交易行为更加意外,也更加知情(了解更多内幕)。短期的内幕人士和他们的公司也倾向于表现出更多关注短期主义的特征。


We examine the relation between insiders’ investment horizon and the information content of their trades with respect to future stock returns. We conjecture that an insider's investment horizon establishes a benchmark for expected patterns of continued trading behavior and thus helps identify unexpected insider trades, which should be more informative in efficient markets. Consistent with this conjecture, the trades of short‐horizon insiders are both more unexpected and more informed, on average, than those of long‐horizon insiders. Short‐horizon insiders and their firms also tend to display characteristics that are associated with a greater focus on short‐termism.

11、证券分析师的技能如何?


当分析师绩效模型的横截面展现成多种技能分布的混合体时,大多数证券分析师被认为是熟练的。分析员表现出不同的技能,有的是高级的,有的是低级的。平均而言,这两种类型的分析师的建议修正后都表现出异常的正收益。这种异质性源于产生新信息的不同能力;所有分析员都可以是处理的信息产生盈利。顶级分析师之所以表现出色,是因为他们更多的建议更具有影响力(与统计上的回报显著相关),而且无论他们的影响力与否,其建议的信息量都更大,大多数研究公司也被认为是有技能的。


The majority of security analysts are identified as skilled when the cross‐section of analyst performance is modeled as a mixture of multiple skill distributions. Analysts exhibit heterogeneous skill—some are high‐type, and some are low‐type. On average, the recommendation revisions of both types exhibit positive abnormal returns. The heterogeneity stems from differential ability to produce new information; all analysts can profitably process news. Top analysts outperform because more of their recommendations are influential (i.e., associated with statistically significant returns) and both their influential and noninfluential recommendations are more informative. A majority of research firms are also identified as skilled.
