Dark pools can restrict access for specific trader types. We compare execution outcomes between dark pools that restrict high frequency trader access and those that do not. We find that trades executed in dark pools with more access restrictions have less order flow information leakage, adverse selection risk and post-trade order imbalances than trades in less restricted pools. Evidence from exogenous dark pool closures demonstrates that these differences are causal. The ability to segment order flow can benefit investors because it allows them to make trade-offs between execution risk and information leakage across different dark venues.
暗池可以限制特定交易者类型的访问。我们比较了限制高频交易者进入和不限制高频交易者进入的暗池之间的执行结果。研究发现,在访问限制较多的暗池中执行的交易比在访问限制较少的暗池中执行的交易具有更小的订单流信息泄漏、逆向选择风险和交易后订单不平衡。来自外源性暗池关闭的证据表明,这些差异是因果关系。分割订单流的能力可以让投资者受益,因为它允许他们在执行风险和信息泄露之间做出权衡。

We analyze interactions between fiscal and monetary stimulus in a new Keynesian model with nominal mortgage debt that can be inflated away. Redistributive transfers are most impactful when followed by a temporary deviation from inflation-targeting monetary policy. Unlike other fiscal policies, redistribution causes inflation even in the absence of long-run debt sustainability problems, and inflating away mortgages results in additional redistribution. In a quantitative model with mortgage refinancing frictions, transfer payments provide much more stimulus than the redistributive effects of inflation. Borrowers gradually refinance after their mortgages are inflated away, dampening their immediate consumption response and reducing their long-run labor supply.
我们在一个新的凯恩斯主义模型中分析了财政和货币刺激之间的相互作用,该模型考虑了名义抵押贷款债务可以通过通货膨胀消除。再分配转移在暂时偏离以通胀为目标的货币政策之后最具影响力。与其他财政政策不同的是,即使在没有长期债务可持续性问题的情况下,再分配也会导致通货膨胀,而通过通货膨胀消除抵押贷款会导致额外的再分配。在抵押贷款再融资摩擦的定量模型中,转移支付提供的刺激远远大于通货膨胀的再分配效应。借款人在抵押贷款膨胀后逐渐进行再融资,抑制了他们的即时消费反应,减少了他们的长期劳动力供应。

The impact of prices on analyst cash flow expectations: Reconciling subjective beliefs data with rational discount rate variation 价格对分析师现金流预期的影响:调和主观信念数据与理性折现率变化

I show that prices impact analyst cash flow expectations and argue this impact can partially reconcile subjective beliefs data with asset pricing models in which investors have rational expectations and discount rate variation drives prices. Previous work argues that correlations of biased analyst cash flow expectations with prices and future returns contradict rational models and imply biased investor expectations distort prices. However, using two instrumental variables for price, I find increases in price unrelated to cash flow news raise analyst cash flow expectations. Based on this empirical finding, I propose a model with rational investors that matches key moments in beliefs data: analysts form biased cash flow expectations by learning from prices that contain discount rate variation. Thus, while stylized facts in beliefs data can be consistent with investors having biased expectations that distort prices, these facts can also be consistent with investors having rational expectations and analysts learning from prices.
我表明价格影响分析师的现金流预期,并认为这种影响可以部分地调和主观信念数据与资产定价模型,其中投资者有理性预期和贴现率变化驱动价格。先前的研究认为,有偏见的分析师现金流预期与价格和未来回报的相关性与理性模型相矛盾,并暗示有偏见的投资者预期扭曲了价格。然而,使用价格的两个工具变量,我发现与现金流新闻无关的价格上涨提高了分析师的现金流预期。基于这一实证发现,我提出了一个理性投资者的模型,该模型与信念数据中的关键时刻相匹配:分析师通过从包含贴现率变化的价格中学习,形成有偏见的现金流预期。因此,虽然信念数据中的程式化事实可能与投资者有偏见的预期一致,扭曲了价格,但这些事实也可能与投资者有理性预期和分析师从价格中学习一致。

We examine the survival prospects, employment profiles, and patient outcomes at private equity (PE)-acquired hospitals. Target hospitals maintain their survival rates while significantly reducing employment and wage expenditures. The number of core medical workers drops temporarily, but returns to its pre-acquisition level in the long run. However, administrative job and wage cuts persist over the long term, particularly at previously nonprofit hospitals. Using proprietary insurance claims data, we find no significant changes in patient demographics or inpatient prices at PE-acquired hospitals. While patient satisfaction declines, there is no evidence of increased patient mortality or readmission rates at PE-acquired hospitals.
我们研究了私募股权(PE)收购医院的生存前景、就业概况和患者结果。目标医院在维持其存活率的同时,显著减少了就业和工资支出。核心医务人员的数量暂时下降,但从长期来看会恢复到获得前的水平。然而,行政工作和工资的削减长期存在,特别是在以前的非营利性医院。使用专有保险索赔数据,我们发现在pe收购的医院中,患者人口统计数据或住院价格没有显著变化。虽然患者满意度下降,但没有证据表明pe收购医院的患者死亡率或再入院率增加。

This paper studies banks’ investment in risk management human capital following the Global Financial Crisis and the advent of stress testing. Our results suggest that ‘Too Big to Fail’ distortions may have weakened large banks’ incentive to invest in risk management talent. Stress testing, which focuses on the largest banks, spurred demand for skilled quantitative risk managers, but only narrowly in anticipation of a test and following poor performance on a test. Stress testing does not affect demand for the over 90 % of risk management jobs not linked to passing tests, limiting its effectiveness in improving risk management practices.
本文研究了全球金融危机和压力测试出现后银行在风险管理人力资本方面的投资。我们的研究结果表明,“太大而不能倒”的扭曲可能削弱了大型银行投资风险管理人才的动力。以大型银行为重点的压力测试刺激了对熟练的定量风险管理人员的需求,但这种需求仅在预期测试和测试表现不佳之后出现。压力测试不影响对90%以上与通过测试无关的风险管理工作的需求,限制了其在改进风险管理实践方面的有效性。

Using global mutual fund and American Depositary Receipt (ADR) data, we test if funds strategically trade cross-listed firms’ equity shares in the most liquid trading location. We find that especially funds that score high on traditional skill measures exhibit a liquidity-based trading venue preference. We identify an informed trading motive as the most likely driver for such behaviour rather than preference based on geographic, economic, cultural, or governance motives. Thus, liquidity picking is associated with fund outperformance and stock selection ability that is not limited to only cross-listed firms. Our tests directly support theories of informed trading in a multi-market setting.
利用全球共同基金和美国存托凭证(ADR)数据,我们测试了基金是否在流动性最强的交易地点战略性地交易交叉上市公司的股票。我们发现,特别是那些在传统技能指标中得分较高的基金,表现出基于流动性的交易场所偏好。我们认为明智的交易动机是这种行为最可能的驱动因素,而不是基于地理、经济、文化或治理动机的偏好。因此,流动性选择与基金的优异表现和选股能力有关,这不仅限于交叉上市公司。我们的测试直接支持多市场环境下的知情交易理论。

Robust difference-in-differences analysis when there is a term structure 当存在期限结构时,稳健的差异中差异分析

For variables with a term structure, the standard difference-in-differences (DiD) model is predisposed toward misspecification, even under random assignment, because of heterogeneity over the maturity spectrum and imperfect matching between treated and control units. Estimated treatment effects that are false, biased, or hard to interpret become a concern. Neither unit fixed effects nor standard term-structure controls resolve the problem. Solutions that overcome imperfect matching involve estimating the term structure of hypothesized treatment, which is also what is economically interesting (regardless of matching efficiency). These issues are not unique to DiD analysis, but are generic to group-assignment settings.
对于具有期限结构的变量,即使在随机分配的情况下,由于成熟度谱上的异质性以及处理单元和控制单元之间的不完美匹配,标准的差中差(DiD)模型也容易出现规格错误。估计的治疗效果是错误的,有偏见的,或难以解释成为一个问题。无论是单位固定效应还是标准期限结构控制都不能解决问题。克服不完美匹配的解决方案涉及估计假设治疗的期限结构,这也是经济上有趣的(不管匹配效率如何)。这些问题并不是DiD分析所特有的,而是组分配设置的一般问题。

Exorbitant privilege? Quantitative easing and the bond market subsidy of prospective fallen angels 过分的特权吗?量化宽松与债券市场对未来堕落天使的补贴

We document capital misallocation in the U.S. investment-grade (IG) corporate bond market, driven by quantitative easing (QE). Prospective fallen angels — risky firms just above the IG cutoff — enjoyed subsidized bond financing in 2009–19. This effect is driven by Fed purchases of securities inducing long-duration IG-focused investors to rebalance their portfolios towards higher-yielding IG bonds. The benefiting firms (i) exploited the sluggish downward adjustment of credit ratings after M&A to finance risky acquisitions with bond issuances, and (ii) increased market share affecting competitors’ employment and investment, but (iii) suffered severe downgrades at the onset of the pandemic.
我们记录了在量化宽松(QE)的推动下,美国投资级(IG)公司债券市场的资本错配。2009 - 2019年,潜在的“堕落天使”——仅高于IG门槛的高风险公司——享受了补贴债券融资。这种效应是由美联储购买证券推动的,这些证券促使关注长期IG债券的投资者重新平衡其投资组合,转向收益率更高的IG债券。受益公司(一)利用并购A后信用评级缓慢下调的机会,通过发行债券为高风险收购融资;(二)增加市场份额,影响竞争对手的就业和投资,但(三)在疫情开始时信用评级遭到严重下调。

How do workplace social connections shape everyday entrepreneurship? Using comprehensive data on millions of American workers across the economy, I find three key patterns. First, entrepreneurial coworkers inspire and teach entrepreneurship: individuals are more likely to become entrepreneurs after working with coworkers who previously led young businesses. Second, these effects predominantly occur within demographic groups, perpetuating lower entrepreneurship rates for women and Black Americans. Third, these workplace spillovers can increase productivity: individuals exposed to relatively successful coworkers subsequently run successful companies too.
职场社会关系如何影响日常创业?通过对美国经济中数百万工人的综合数据分析,我发现了三个关键模式。首先,具有创业精神的同事会激发并传授创业精神:在与曾经领导过初创企业的同事共事后,个人更有可能成为企业家。其次,这些影响主要发生在人口群体中,使女性和美国黑人的创业率长期处于较低水平。第三,这些职场溢出效应可以提高生产率:接触到相对成功的同事的个人随后也会经营成功的公司。

Banks use trading as a vehicle to take risk. Using high-frequency regulatory data, we estimate the sensitivity of weekly bank trading profits to aggregate equity, fixed-income, credit, currency, and commodity risk factors. Our estimates imply that U.S. banks had large trading exposures to equity market risk before the Volcker Rule, which they curtailed afterwards. Credit and currency risk exposures were smaller. The results hold up in a quasi-natural experiment that exploits the phased-in introduction of reporting requirements for identification. Total trading-book risk was also curtailed afterwards with material financial stability implications and no evidence of migration to other bank activities.
银行将交易作为承担风险的工具。利用高频监管数据,我们估计了每周银行交易利润对股票、固定收益、信贷、货币和商品风险因素的敏感性。我们的估计表明,在沃尔克规则出台之前,美国的银行在股票市场上有很大的交易风险敞口,而在沃尔克规则出台后,这些风险敞口被削减了。信贷和货币风险敞口较小。这个结果在一个准自然的实验中得到了证实,该实验利用了分阶段引入的报告要求来进行识别。交易账簿的总风险随后也受到了限制,对金融稳定产生了重大影响,而且没有证据表明会转移到其他银行活动。
