We introduce an easy-to-compute measure of board advising: Director Connections. This is the number of unique directors that a firm’s outside directors are connected to through common board service. We find that as firm complexity increases: Director Connections increases, firm value increases with Director Connections, and announcement returns to director appointments increases. The idea that connected directors are valuable advisors is further supported by the findings that connected directors have higher human capital, are paid more, disproportionately represented on advising committees, and do not improve monitoring effectiveness. Our contribution is to document that director connections are valuable in complex firms.
我们介绍了一个易于计算的董事会建议衡量标准:董事关系。这是一家公司的外部董事通过共同董事会服务与之联系的唯一董事的数量。我们发现,随着公司复杂性的增加:董事关系的增加,公司价值随着董事关系的增加而增加,董事任命的公告回报增加。有关联的董事是有价值的顾问,这一观点得到了以下研究结果的进一步支持:有关联的董事拥有更高的人力资本,薪酬更高,在咨询委员会中的比例不成比例,而且不会提高监督效率。我们的贡献是证明了董事关系在复杂的公司中是有价值的。

Investment Risk, CDS Insurance, and Firm Financing 投资风险、CDS保险和企业融资
Pub Date : 2018-12-18 DOI: 10.2139/ssrn.1770066
Murillo Campello, R. Matta
This paper develops a model of CDS demand when investment is subject to economic fluctuations and verification is imperfect. We show that CDS overinsurance (insurance in excess of renegotiation proceeds) is procyclical and allows for greater financing of firms with positive NPV projects. In bad times, CDS overinsurance triggers the early liquidation of firms with low continuation values. Our analysis explains the optimality of CDS contracting and reconciles evidence showing that CDSs are most beneficial for firms that are safer and have higher continuation values. The model generates a number of empirical predictions and provides insights on the regulation of CDS markets.
本文建立了投资受经济波动影响时CDS需求的模型,但验证不完善。我们表明,CDS过度保险(超过重新谈判收益的保险)是顺周期的,并允许具有正NPV项目的公司获得更多融资。在经济不景气的时候,CDS的过度保险会导致延续价值较低的公司提前清算。我们的分析解释了CDS契约的最优性,并调和了表明CDS对更安全、具有更高延续值的公司最有利的证据。该模型产生了许多经验预测,并提供了对CDS市场监管的见解。

An Asset Pricing Approach to Testing General Term Structure Models 检验一般期限结构模型的资产定价方法
Pub Date : 2018-05-18 DOI: 10.2139/ssrn.1578354
B. Christensen, Michel van der Wel
We develop a new empirical approach to term structure analysis that allows testing for time-varying risk premiums and arbitrage opportunities in models with both unobservable factors and factors identified as the innovations to observed macroeconomic variables. Factors can play double roles as both covariance-generating common shocks driving yields and determinants of market prices of risk in cross-sectional pricing. The evidence favors time-varying risk prices significantly related to the second Stock–Watson principal component of macroeconomic variables and to changes in the industrial production index. Our preferred specification includes these two observable and two unobservable factors, with the no-arbitrage condition imposed.
我们开发了一种新的经验方法来进行期限结构分析,允许在模型中测试时变风险溢价和套利机会,模型中既有不可观察因素,也有被确定为观察到的宏观经济变量的创新因素。在横截面定价中,因素可以扮演双重角色,既可以产生驱动收益率的协方差共同冲击,也可以决定风险的市场价格。证据支持时变风险价格与宏观经济变量的第二个Stock-Watson主成分和工业生产指数的变化显著相关。我们的首选规范包括这两个可观察因素和两个不可观察因素,并施加了无套利条件。

High Leverage and Willingness to Pay: Evidence from the Residential Housing Market 高杠杆与支付意愿:来自住宅市场的证据
Pub Date : 2018-01-26 DOI: 10.2139/ssrn.1927294
Itzhak Ben-David
In pursuit of understanding the mechanism that relates the expansion in credit to the increase in real-estate prices during the real-estate bubble, I explore transaction-level data for 1994-2008. I document a strong correlation between borrowing at high leverage (>95% loan to value) and paying the full listing price or above. Homebuyers in these transactions pay prices that are higher than market prices by 3.4% ($5,700 on average) and they are 22.7% more likely to default on their mortgages, relative to other highly leveraged borrowers. The correlation between leverage and paying high prices is stronger beyond what a mechanical relation predicts: there is a discontinuity in the average leverage around the full listing price. The correlation is stronger for financially constrained and unsophisticated homebuyers, and in areas of high past price growth (indicative of buyer optimism). The study highlights the importance of buyer sophistication, financial constraints, and beliefs in determining prices and leverage.
为了理解房地产泡沫期间信贷扩张与房地产价格上涨之间的联系机制,我研究了1994-2008年的交易水平数据。我记录了高杠杆借款(贷款价值比>95%)与支付全部上市价格或更高价格之间的强烈相关性。在这些交易中,购房者支付的价格比市场价格高出3.4%(平均5700美元),与其他高杠杆借款人相比,他们拖欠抵押贷款的可能性要高22.7%。杠杆与支付高价之间的相关性,超出了机械关系所能预测的程度:在全部上市价格附近,平均杠杆存在不连续。这种相关性对于财政拮据和不成熟的购房者,以及在过去价格高增长的地区(表明买家乐观)更强。该研究强调了买家成熟度、财务约束以及在决定价格和杠杆方面的信念的重要性。

Illiquidity Premia in the Equity Options Market 股票期权市场的非流动性溢价
Pub Date : 2017-09-21 DOI: 10.2139/ssrn.1784868
Peter F. Christoffersen, Ruslan Goyenko, Kris Jacobs, M. Karoui
Standard option valuation models leave no room for option illiquidity premia. Yet we find the risk-adjusted return spread for illiquid over liquid equity options is $3.4%$ per day for at-the-money calls and $2.5 %$ for at-the-money puts. These premia are computed using option illiquidity measures constructed from intraday effective spreads for a large panel of U.S. equities, and they are robust to different empirical implementations. Our findings are consistent with evidence that market makers in the equity options market hold large and risky net long positions, and positive illiquidity premia compensate them for the risks and costs of these positions.

Authors have furnished an Internet Appendix, which is available on the Oxford University Press Web site next to the link to the final published paper online.
标准期权估值模型没有考虑期权非流动性溢价。然而,我们发现,非流动性股票期权与流动性股票期权经风险调整后的收益差为每日3.4美元的平价看涨期权和每日2.5美元的平价看跌期权。这些溢价是使用期权非流动性指标来计算的,这些指标是由大量美国股票的日内有效价差构建的,它们对不同的实证实施都是稳健的。我们的研究结果与证据一致,即股票期权市场的做市商持有大量高风险的净多头头寸,而正的非流动性溢价补偿了这些头寸的风险和成本。2012年9月25日收稿;编辑决定2017年9月17日,编辑Andrew Karolyi作者们提供了一份互联网附录,可以在牛津大学出版社的网站上找到,就在最终发表论文的链接旁边。

Do Locals Know Better? A Comparison of the Performance of Local and Foreign Institutional Investors 当地人知道得更多吗?本地和外国机构投资者的业绩比较
Pub Date : 2017-05-09 DOI: 10.2139/ssrn.1361747
Miguel A. Ferreira, Pedro Matos, J. Pereira, P. Pires
We compare the performance of local versus foreign institutional investors using a comprehensive data set of equity holdings in 32 countries during the 2000–2010 period. We find that foreign institutions perform as well as local institutions on average, but only domestic institutions show a trading pattern consistent with an information advantage. Our results suggest a smart-money effect of local institutions in countries subject to higher information asymmetry, non-English speaking countries, countries with less efficient stock markets, with poor investor protection, or high levels of corruption. The local advantage is more pronounced in periods of market turmoil and in illiquid stocks.
我们使用2000-2010年期间32个国家的股票持有的综合数据集比较了本地和外国机构投资者的表现。我们发现,外资机构的平均表现与本土机构一样好,但只有国内机构表现出符合信息优势的交易模式。我们的研究结果表明,在信息不对称程度较高的国家、非英语国家、股票市场效率较低、投资者保护不力或腐败程度较高的国家,当地机构存在“聪明钱”效应。在市场动荡和流动性差的股票中,本地优势更为明显。

Empirical Investigation of an Equity Pairs Trading Strategy 股票对交易策略的实证研究
Pub Date : 2017-04-08 DOI: 10.2139/ssrn.1361293
Huafeng (Jason) Chen, Shaojun Chen, Zhuo Chen, Feng Li
We show that an equity pairs trading strategy generates large and significant abnormal returns. We find that this return is not driven purely by the short-term reversal of returns. The evidence related to the cross-sectional variation, the time-series variation, and the persistence of the pairs trading profits, and the determinants of return correlations is consistent with the delay in information diffusion as the driver for the pairs trading strategy. Evidence from the liquidity factor and the recent financial crisis suggests that the short-term liquidity provision is not the main cause of the pairs trading strategy.
我们证明了股票对交易策略产生了巨大而显著的异常收益。我们发现,这种回报并非纯粹由回报的短期逆转所驱动。横截面变化、时间序列变化、交易收益持续性和收益相关性决定因素的证据表明,信息扩散的延迟是交易策略的驱动因素。来自流动性因素和最近金融危机的证据表明,短期流动性供应不是货币对交易策略的主要原因。

Competition for Managers and Corporate Governance 经理人竞争与公司治理
Pub Date : 2016-10-01 DOI: 10.2139/ssrn.1572994
V. Acharya, Marc Gabarro, P. Volpin
Separation between CEO and Chairman of the Board is typically viewed as evidence of good corporate governance. Surprisingly, the literature has failed so far to uncover any significant relation between CEO/Chairman duality and firm performance. By distinguishing between periods with and without CEO turnover, we empirically identify two o setting effects: the correlation between duality and performance is positive around CEO turnover and negative otherwise. This suggests that the competition for managerial talent forces firms to combine CEO and Chairman in order to attract more skilled CEOs at the cost of reducing governance standards.
首席执行官和董事会主席分开通常被视为良好公司治理的证据。令人惊讶的是,迄今为止,文献未能揭示CEO/董事长双重身份与公司绩效之间的任何显著关系。通过区分有和没有CEO离职的时期,我们实证地确定了两种设置效应:二元性与绩效之间的相关性在CEO离职时为正相关,在其他方面为负相关。这表明,对管理人才的竞争迫使企业将CEO和董事长结合起来,以降低治理标准为代价,吸引更多有技能的CEO。

Investor Sentiment and Economic Forces 投资者情绪和经济力量
Pub Date : 2016-07-18 DOI: 10.2139/ssrn.1991244
Junyan Shen, Jianfeng Yu, Shen Zhao
Economic theory suggests that pervasive factors should be priced in the cross-section of stock returns. However, our evidence shows that portfolios with higher risk exposure do not earn higher returns. More importantly, our evidence shows a striking two-regime pattern for all 10 macro-related factors: high-risk portfolios earn significantly higher returns than low-risk portfolios following low-sentiment periods, whereas the exact opposite occurs following high-sentiment periods. These findings are consistent with a setting in which market-wide sentiment is combined with short-sale impediments and sentiment-driven investors undermine the traditional risk-return tradeoff, especially during high-sentiment periods.
经济理论认为,普遍因素应该在股票收益的横截面中定价。然而,我们的证据表明,高风险的投资组合并没有获得更高的回报。更重要的是,我们的证据显示,在所有10个宏观相关因素中,存在惊人的两种模式:在情绪低迷时期,高风险投资组合的回报明显高于低风险投资组合,而在情绪高涨时期,情况恰恰相反。这些发现与市场整体情绪与卖空障碍相结合的情况是一致的,情绪驱动的投资者破坏了传统的风险回报权衡,尤其是在情绪高涨的时期。
