1、好的套利,坏的套利


本文区分由十国集团货币(G-10货币)构建而成的“好的”和“坏的”套利交易:好的套利交易具有较高的夏普比率,有时具有正回报偏态,而坏的套利交易则具有较低的夏普比率和高度的负回报偏态。令人惊讶的是,好的套利交易并不涉及澳元和日元等典型套利货币。好的套利交易和坏的套利交易之间的区别,极大地改变了我们对货币套利交易回报的理解,并使一些解释无效,例如引起回报偏态和崩盘风险的解释变得无效。


We distinguish between “good” and “bad” carry trades constructed from Group of Ten (G-10) currencies. The good trades exhibit higher Sharpe ratios and sometimes positive return skewness, in contrast to the bad trades, which have both substantially lower Sharpe ratios and highly negative return skewness. Surprisingly, good trades do not involve the most typical carry currencies like the Australian dollar and Japanese yen. The distinction between good and bad carry trades significantly alters our understanding of currency carry trade returns, and invalidates, for example, explanations invoking return skewness and crash risk.

2、私募股权的中介:资产配置顾问的作用


私募股权的中介存在着非流动性投资、要求专业投资者和高度的信息不对称的特性。本文使用一个独特的设置来实证评估有关中介的理论预测。资产配置顾问(PA)已变得几乎无处不在,但在风险投资和房地产基金中,与PA相关的异常回报显著降低,这与投资者使用影响力兜售相关。但聘请顶级PA的收购基金,以及首次聘请PA的房地产基金风险基金的回报较高,而与PA附属的基金回报率波动较小,这与认证一致。研究结果表明,在私募行业,中介的动机是异质的。


Intermediation in private equity involves illiquid investments, professional investors, and high information asymmetry. We use this unique setting to empirically evaluate theoretical predictions regarding intermediation. Using placement agents has become nearly ubiquitous, but agents are associated with significantly lower abnormal returns in venture and real estate funds, consistent with investor capture and influence peddling. However, returns are higher for buyout funds employing a top-tier agent and for first-time real estate and venture funds employing an agent, and are less volatile for agent-affiliated funds, consistent with a certification role. Our results suggest heterogeneous motives for intermediation in the private equity industry.

3、具有动态做市商库存和财富的可行的期权定价框架


本文建立了一个可控动态模型,即资本有限的指数期权做市商模型,这个模型可根据动态性资产、做市商期权持有量和财富来求解方差风险溢价和期权价格。做市商吸收了最终用户的正需求,并在遭受损失时要求更高的负方差风险溢价。本文使用指数收益、期权和库存来估算模型,发现模型运行良好,尤其是在金融危机期间。将该模型与简化形式的随机波动模型进行比较,数据结果强烈拒绝了简化形式的随机波动模型施加的限制。


We develop a tractable dynamic model of an index option market maker with limited capital. We solve for the variance risk premium and option prices as a function of the asset dynamics and market maker option holdings and wealth. The market maker absorbs end users’ positive demand and requires a more negative variance risk premium when she incurs losses. We estimate the model using returns, options, and inventory and find that it performs well, especially during the financial crisis. The restrictions imposed by nested existing reduced-form stochastic-volatility models are strongly rejected in favor of the model with a market maker.

4、随时间变化的投资机会、参数不确定性和模糊厌恶情况下的最佳投资组合


本文研究了可预测性对模糊厌恶型长期投资者的最佳资产配置的影响,并在考虑参数不确定性的情况下分析多元风险-收益权衡的期限结构。使用期限价差和股息/价格比率作为附加的预测变量,将模型校准为美国股票、长期债券、现金、房地产和黄金的实际回报,并且从长期来看,研究发现了最优资产配置受到由估计误差引起的协方差结构的显著影响。模糊厌恶型长期投资者最佳投资组合向看似效率低下的投资组合倾斜,因为相对于估计误差,这样操作稳健性最高。


We study the implications of predictability on the optimal asset allocation of ambiguity-averse long-term investors and analyze the term structure of the multivariate risk–return trade-off considering parameter uncertainty. We calibrate the model to real returns of U.S. stocks, long-term bonds, cash, real estate, and gold using the term spread and the dividend–price ratio as additional predictive variables, and we show that over long horizons, the optimal asset allocation is significantly influenced by the covariance structure induced by estimation errors. The ambiguity-averse long-term investor optimally tilts his or her portfolio toward a seemingly inefficient portfolio, which shows maximum robustness against estimation errors.

5、股息风险溢价


本文研究了国际市场上的股息,债券和股票指数交易预期超额收益的时间变化。引入了一种新的股息风险因素,补充了学者Cochrane和Piazzesi(2005)研究得出债券风险因素。通过汇总 4 个地区(美国、英国、欧元区和日本)的研究结果得出全球股息和债券的影响因素。全球双因素模型适用于解释大多数发达市场的摩根士丹利资本国际 (MSCI) 国家指数的超额回报,以及各种其他测试资产。研究结果强调了股息和债券远期曲线中包含的信息的价值,并暗示了国际风险溢价的实质性协同作用。


This article studies time variation in the expected excess returns of traded claims on dividends, bonds, and stock indices for international markets. We introduce a novel dividend risk factor that complements the bond risk factor of Cochrane and Piazzesi (2005). By aggregating over 4 regions (United States, United Kingdom, Eurozone, and Japan), we create global dividend and bond factors. Our global 2-factor model captures the excess returns of most Morgan Stanley Capital International (MSCI) country indices, as well as a variety of other test assets. Our findings highlight the value of the information contained in dividend and bond forward curves and suggest substantial comovement in international risk premia.

6、财务激励和信贷员行为:不完整的合同下的多任务处理和工作分配


本文研究了向信贷员提供非线性薪酬结构的影响,该结构奖励贷款额并惩罚不良业绩。利用一家大型国际商业银行提供的独特数据集,研究了信贷员的主要活动:贷款勘探、筛选和监控。研究发现,当信贷员面临失去奖金的风险时,他们会增加潜在客户和监督的力度。研究进一步表明,在接近月底奖金发放时,信贷员会更多地调整自己的行为。对于在银行任职时间较长的信贷员来说,这些影响更为明显。


We investigate the implications of providing loan officers with a nonlinear compensation structure that rewards loan volume and penalizes poor performance. Using a unique data set provided by a large international commercial bank, we examine the main activities that loan officers perform: loan prospecting, screening, and monitoring. We find that when loan officers are at risk of losing their bonuses, they increase prospecting and monitoring. We further show that loan officers adjust their behavior more toward the end of the month when bonus payments are approaching. These effects are more pronounced for loan officers with longer tenures at the bank.

7、银行分行放松管制和银团贷款市场


银行监管的变化如何影响银团贷款市场?由于银行分行网络和贷款联合使得银行能够分散地域信贷风险,本文调查了1994年《里格尔--尼尔州际分行和银行效率法案》的分段实施情况。该法案只改变了州外商业银行的法律框架,研究发现,银行分行放松管制减少了银团贷款的发放,但刺激了对公司的双边贷款。与供应驱动的替代效应一致,这种转变也反映在利率利差中。研究结果表明,银行监管的改变可以显著改变不同贷款类型之间的信贷分配。


How do changes in banking regulation affect the syndicated loan market? Because branch networks and loan syndication both enable banks to diversify geographical credit risk, we investigate the staggered implementation of the Riegle–Neal Interstate Branching and Banking Efficiency Act of 1994. Exploiting that the act only changed the legal framework for out-of-state commercial banks, we find that branching deregulation decreased syndicated loan issuance but spurred bilateral lending to corporations. Consistent with a supply-driven substitution effect, this shift is also reflected in interest rate spreads. Our results suggest that changes to banking regulation can substantially alter credit allocation across loan types.

8、杠杆企业的动态道德风险和风险转移激励


本文开发了一个易于分析的模型,该模型将债券持有人和股东之间的风险转移问题,以及股东和管理者之间的道德风险问题结合起来。最优契约约束了股东和管理者。契约的灵活性允许着股东在公司盈利能力表现良好时,放松对管理者的激励约束。因此,最优契约放大了利润上行空间,增加了股东对风险转移的兴趣。一些实证研究发现风险转移与杠杆之间存在正相关关系,而另一些实证研究则发现其存在负相关关系。该模型预测了风险转移和杠杆之间的非单调关系,并可以调和一些看似矛盾的实证结果。


I develop an analytically tractable model that integrates the risk-shifting problem between bondholders and shareholders with the moral-hazard problem between shareholders and the manager. An optimal contract binds shareholders and the manager, and this contract’s flexibility allows shareholders to relax the manager’s incentive constraint following a “good” profitability shock. Thus, the optimal contract amplifies the upside and thereby increases shareholder appetite for risk shifting. Whereas some empirical studies find a positive relation between risk shifting and leverage, others find a negative relation. This model predicts a non-monotonic relation between risk shifting and leverage and can reconcile these contradictory empirical findings.

8、内幕交易:真正保护美国投资者的是什么?


本文考察了美国投资者的保护机制限制内幕交易的能力,这些1934年《证券交易法》(简称规则)第16(b)条并未提及。研究发现,在这种情况下,美国内部人士执行的短线交易是:1)每天以大约15个基点击败市场:2)在令人失望的财报公布前有计划地撤资。这些结果表明,限制短期往返内幕交易的明线规则,在保护外部投资者免受美国内部知情人士的侵害方面发挥了重要作用。


I examine the ability of the U.S. investor protection regime to limit insider trading returns, absent Section 16(b) of the Securities Exchange Act of 1934 (the short-swing rule). I find that in this setting, U.S. insiders execute short-swing trades that i) beat the market by approximately 15 basis points per day and ii) systematically divest ahead of disappointing earnings announcements. These results indicate that the bright-line rule restricting short-horizon round-trip insider trading plays a substantial role in protecting outside investors from privately informed insiders in the United States.

10、即将到来的浪潮:新兴市场投资者把钱放在哪里?


本研究利用国家和机构层面的数据,发现新兴市场(EM)投资者的“即将到来的浪潮”系统性地高估或低估了他们的股票投资组合持有量,反映了过去外国资本和贸易流动的影响。本文将这一发现解释为支持学者van Nieuwerburgh和Veldkamp(2009)的信息禀赋假说。过去强劲的资本和贸易流动创造了一种信息优势,导致新兴市场投资者过度增持特定国外市场股票,甚至相对于发达市场投资者而言也是如此。本文还根据投资公司与其母公司总部之间的关系构建新颖的信息优势代理,对信息捐赠假说进行预测。这些代理也为国际投资组合的配置提供了可靠的解释。


Using country- and institution-level data, we find that the “coming wave” of emerging- market (EM) investors systematically over- or underweight their equity portfolio holdings in a way that reflects the influences of past capital and trade flows from a foreign country. We interpret this finding as support for van Nieuwerburgh and Veldkamp (2009) information endowment hypothesis. Strong past capital and trade flows create an information advantage that leads EM investors to disproportionately overweight a given foreign market, even relative to developed market investor counterparts. We also pursue predictions of the information endowment hypothesis by constructing novel information-advantage proxies based on relationships among investment firms and the headquarters of their parent companies. These proxies also offer reliable explanatory power for international portfolio allocations.
