SP this period coincides with the beginning of the global outbreak of COVID-19. This claim is in line with the view that, due to the stringent screening, Islamic equity investments provide hedging benefits during market downfalls. In this paper, we investigate whether Islamic equity indices (IEIs), in general, exhibit hedging benefits during the COVID-19 period for global, the US, and European markets. We also test whether the difference in Shari’ah screening criteria has any impact on the relative performance of Islamic equity investments. Our empirical findings support the hypothesis that IEIs do provide hedging benefits during severe market downfalls especially those following the market value of equity-based Shari’ah screening criteria. The excess performance, however, is associated largely with higher systematic risk suggesting that hedging benefits come at an additional cost. The results remained robust following the Dual Beta model and Logistic smooth autoregression model.
SP 这一时期恰好是 COVID-19 在全球爆发的初期。这种说法与伊斯兰股票投资因严格筛选而在市场下跌期间提供对冲收益的观点一致。在本文中,我们研究了在 COVID-19 期间,伊斯兰股票指数(IEIs)在全球、美国和欧洲市场是否普遍表现出对冲效益。我们还检验了伊斯兰教法筛选标准的差异是否会对伊斯兰股票投资的相对表现产生影响。我们的实证研究结果支持这一假设,即在市场严重下挫时,伊斯兰股权投资确实能提供对冲收益,尤其是那些遵循基于伊斯兰教法筛选标准的股票市值的投资。然而,超额收益在很大程度上与较高的系统性风险有关,这表明对冲收益需要付出额外的成本。采用双贝塔模型和逻辑平稳自回归模型后,结果依然稳健。

What’s in Your Real Asset Portfolio? Introducing RASA TM 你真正的资产组合里有什么?介绍RASA TM
Pub Date : 2020-05-01 DOI: 10.2139/ssrn.3766481

In prior research we highlighted the diversity of real assets in terms of their sensitivities to the equity and bond markets and to macroeconomic factors such as growth and inflation. We now extend our analysis to real asset portfolios. Do portfolios exhibit similar characteristics and performance? Or, like the real assets themselves, do real asset portfolios display heterogeneity, with a given portfolio serving a particular investment goal and purpose? We use our Real Asset Sensitivity Analysis (RASA TM) framework to help CIOs estimate the macroeconomic and market sensitivities of a real asset portfolio. Institutional investors have increased their allocations to real assets, either assembling the real asset portfolio themselves from the ground up; investing in a third-party real asset fund; or some combination of the two. To illustrate the diversity of real asset portfolios, we examine third-party public, liquid, real asset funds. RASA sensitivities differ considerably across funds and can differ even when funds have similar broad asset allocations. Institutional investors can use RASA to gauge whether a real asset fund, or custom portfolio, aligns with their investment objectives. Using RASA, we identify fund groups that are likely suited for distinct economic environments. An investor can use this information to select funds that may achieve a targeted investment objective-oriented strategy such as Inflation Protection, Growth, or Growth Protection.
在之前的研究中,我们强调了实物资产对股票和债券市场以及经济增长和通货膨胀等宏观经济因素的敏感性的多样性。我们现在将分析扩展到实际资产组合。投资组合是否表现出相似的特征和表现?或者,就像实物资产本身一样,实物资产组合是否表现出异质性,一个给定的投资组合是否服务于特定的投资目标和目的?我们使用我们的真实资产敏感性分析(RASA TM)框架来帮助首席信息官估计真实资产组合的宏观经济和市场敏感性。机构投资者增加了对实物资产的配置,要么自己从头开始组装实物资产组合;投资第三方实物资产基金;或者两者的某种组合。为了说明实物资产组合的多样性,我们考察了第三方公共、流动、实物资产基金。不同基金对RASA的敏感度差异很大,即使基金拥有相似的广泛资产配置,也可能存在差异。机构投资者可以使用RASA来衡量真实资产基金或定制投资组合是否符合他们的投资目标。使用RASA,我们确定可能适合不同经济环境的基金集团。投资者可以使用这些信息来选择可能实现有针对性的投资目标导向策略的基金,如通货膨胀保护、增长保护或增长保护。

Non-answers during Conference Calls 电话会议期间无人接听
Pub Date : 2020-04-24 DOI: 10.2139/SSRN.3310360
Ian D. Gow, D. Larcker, Anastasia A. Zakolyukina
We construct a novel measure of disclosure choice by firms. Our measure is computed using linguistic analysis of conference calls to identify whether a manager’s response to an analyst question is a “non-answer.” Using our measure, about 11% of analyst questions elicit non-answers from managers, a rate that is stable over time and similar across industries. A useful feature of our measure is that it enables an examination of disclosure choice within a call. Analyst questions with a negative tone, greater uncertainty, greater complexity, or requests for greater detail are more likely to trigger non-answers. We find that performance-related questions tend to be associated with non-answers, and this association is weaker when performance news is favorable. We also find analyst questions about proprietary information are associated with non-answers, and this association is stronger when firm competition is more intense.
我们构建了一个衡量企业信息披露选择的新方法。我们的测量是使用电话会议的语言分析来计算的,以确定经理对分析师问题的回答是否为“不回答”。使用我们的测量方法,大约11%的分析师问题没有得到管理人员的回答,这一比例随着时间的推移是稳定的,在各个行业都是相似的。我们的衡量标准的一个有用的特点是,它可以检查调用中的披露选择。分析师提出的带有负面语气的问题、更大的不确定性、更大的复杂性或要求更详细的问题更有可能引发不回答。我们发现,与绩效相关的问题往往与无答案相关联,而当业绩消息有利时,这种关联较弱。我们还发现,分析师关于专有信息的问题与无答案相关,而且当企业竞争越激烈时,这种关联越强。

This paper shows the relationship between corporate social responsibility and firm’s value, respect of the consumer awareness, is different across industries. There are industries that advertising firm’s CSR ratings could benefit the firm’s value. And there are industries that the firm value would be hurt when advertising on it’s CSR rating. There are also industries that show no significant relationship on whether advertising on CSR rating would impact the firm’s value. Important is, the result is varied by industries and it is misspecified if mixed the market together despite the industry effect and only look at the overall conclusion.
本文表明,企业社会责任与企业价值观、尊重消费者意识之间的关系在不同行业是不同的。在某些行业,广告公司的社会责任评级可能有利于公司的价值。而且有些行业的企业价值会因为企业社会责任评级而受到损害。在企业社会责任评级广告是否会影响企业价值方面,也有一些行业没有显示出显著的关系。重要的是,结果因行业而异,如果将市场混合在一起,不顾行业效应,只看整体结论,结果是错误的。

Corporation's Performance Measurements and Corporates’ Pension Plan Characteristics 企业绩效评估与企业养老金计划特征
Pub Date : 2020-04-22 DOI: 10.2139/ssrn.3583080
Jiacong Wei
Whilst pension assets (liabilities) are often neglected by external investors when making investment decisions, pension assets (liabilities) have a stealthy effect on the evaluation of corporates’ performance. This paper studied the question of how pension assets (liabilities) are correlated with a holistic set of performance measurements including financial health, profitability, productivity, transformation, and social responsibility. Additional assessments are made to discover the driver of the differences in performance within the characteristics of pension plans.
虽然养老金资产(负债)在进行投资决策时往往被外部投资者所忽视,但养老金资产(负债)对企业绩效的评价却有着潜在性的影响。本文研究了养老金资产(负债)如何与包括财务健康、盈利能力、生产率、转型和社会责任在内的一系列整体绩效指标相关联。还进行了额外的评估,以发现养恤金计划特点范围内业绩差异的驱动因素。

News Vs Sentiments: Impact of Monetary Policy Announcement on Developed and Developing Countries’ Market Performance 新闻与情绪:货币政策公告对发达国家和发展中国家市场表现的影响
Pub Date : 2020-04-01 DOI: 10.2139/ssrn.3681241
Jazib Ansari, D. Siddiqui
This paper investigates the impact of monetary policy announcements on the performance of the stock market in twenty countries (10 Developed and 10 developing). Exchange rate changes and changes in bond yield were taken as control. Daily basis Panel data was used with daily frequency for five (5) years (2014 – 2018). An impact of these selected independent variables on the stock market index is estimated using the regression model and Panel Least Square model. Monetary policy data has been run in three different lags i.e. lag (0), lag (-1, -2, -3, -4), and lag (1, 2, 3, 4) in order to check the availability of monetary policy impact in pre and post announcement dates also, while the other variables run on a single lag. It is observed that the stock market of developed countries has a significant relation with monetary policy announcements, however, these announcements showed an insignificance relation with the stock market index in the case of developing countries. Moreover, exchange rates seem to have a significant effect on markets of both developing and developed countries, whereas bond yield seems to have a significant effect on the stock market of Developing countries only.
本文研究了货币政策公告对20个国家(10个发达国家和10个发展中国家)股市表现的影响。以汇率变化和债券收益率变化为控制因素。每日基础面板数据以每日频率使用五(5)年(2014 - 2018)。使用回归模型和面板最小二乘模型估计这些选定的自变量对股票市场指数的影响。货币政策数据以三种不同的滞后运行,即滞后(0),滞后(-1,-2,-3,-4)和滞后(1,2,3,4),以检查货币政策影响在公告日期前后的可用性,而其他变量也在单一滞后上运行。可以看出,发达国家的股市与货币政策公告有显著的关系,而发展中国家的货币政策公告与股市指数的关系不显著。此外,汇率似乎对发展中国家和发达国家的市场都有重大影响,而债券收益率似乎只对发展中国家的股票市场有重大影响。

The Value of ETF Liquidity ETF流动性的价值
Pub Date : 2020-03-26 DOI: 10.2139/ssrn.3561531

We model how ETFs compete and set fees. We show that ETF secondary market liquidity plays a key role in determining fees and leads to liquidity clienteles. More liquid ETFs charge higher fees in equilibrium and attract shorter horizon investors that are more sensitive to liquidity than to fees. The higher turnover of these investors sustains the ETF's high liquidity, allowing the ETF to maintain a higher fee and extract a rent. These liquidity rents create a first-mover advantage among ETFs and impact investor welfare. Our empirical tests confirm the presence of liquidity clienteles and show that ETF fee differentials provide a novel measure of the value of liquidity. Our findings resolve the apparent paradox that ETFs with higher fees than their competitors can not only survive, but flourish in equilibrium due to the value of liquidity.
我们对etf如何竞争和设定费用进行建模。我们的研究表明,ETF二级市场的流动性在决定费用和导致流动性客户方面起着关键作用。流动性更强的etf在均衡情况下收取更高的费用,并吸引对流动性比费用更敏感的短期投资者。这些投资者的高周转率维持了ETF的高流动性,使ETF能够维持较高的费用并提取租金。这些流动性租金在etf中创造了先发优势,并影响了投资者的福利。我们的实证测试证实了流动性客户的存在,并表明ETF费用差异提供了一种衡量流动性价值的新方法。我们的研究结果解决了一个明显的悖论,即费用高于竞争对手的etf不仅可以生存,而且由于流动性的价值而在均衡中蓬勃发展。

A Fisherian Approach to Financial Crises: Lessons from the Sudden Stops Literature 对金融危机的fisher方法:从突然停止的文学中得到的教训
Pub Date : 2020-03-01 DOI: 10.2139/ssrn.3657199
Javier Bianchi, Enrique G. Mendoza
Sudden Stops are financial crises defined by a large, sudden current-account reversal. They occur in both advanced and emerging economies and result in deep recessions, collapsing asset prices, and real exchange-rate depreciations. They are preceded by economic expansions, current-account deficits, credit booms, and appreciated asset prices and real exchange rates. Fisherian models (i.e. models with credit constraints linked to market prices) explain these stylized facts as an outcome of Irving Fisher's debt-deflation mechanism. On the normative side, these models feature a pecuniary externality that provides a foundation for macroprudential policy (MPP). We review the stylized facts of Sudden Stops, the evidence on MPP use and effectiveness, and the findings of the literature on Fisherian models. Quantitatively, Fisherian amplification is strong and optimal MPP reduces sharply the size and frequency of crises, but it is also complex and potentially time-inconsistent, and simple MPP rules are less effective. We also provide a new MPP analysis incorporating investment. Using a constant debt-tax policy, we construct a crisis probability-output frontier showing that there is a tradeoff between financial stability and long-run output (i.e., reducing the probability of crises reduces long-run output).

突然停止是指金融危机,其特征是经常账户突然出现大规模逆转。它们在发达经济体和新兴经济体都有发生,并导致深度衰退、资产价格暴跌和实际汇率贬值。它们之前是经济扩张、经常项目赤字、信贷繁荣、资产价格和实际汇率升值。费雪模型(即信用约束与市场价格挂钩的模型)将这些风格化的事实解释为欧文·费雪债务-通缩机制的结果。在规范方面,这些模型具有货币外部性,为宏观审慎政策(MPP)提供了基础。我们回顾了突然停止的程式化事实,关于MPP使用和有效性的证据,以及关于费舍尔模型的文献发现。从数量上看,费希尔放大效应很强,最优MPP可以大幅减少危机的规模和频率,但它也很复杂,可能存在时间不一致性,简单的MPP规则效果较差。我们还提供了一个新的MPP分析纳入投资。使用恒定的债务-税收政策,我们构建了一个危机概率-产出边界,表明在金融稳定和长期产出之间存在权衡(即减少危机的概率会减少长期产出)。(版权:爱思唯尔)

The Corporate Finance of Multinational Firms 跨国公司的公司融资
Pub Date : 2020-02-01 DOI: 10.2139/ssrn.3535761
Isil Erel, Yeejin Jang, M. Weisbach
An increasing fraction of firms worldwide operate in multiple countries. We study the costs and benefits of being multinational in firms’ corporate financial decisions and survey the related academic evidence. We document that, among U.S. publicly traded firms, the prevalence of multinationals is approximately the same as domestic firms, using classification schemes relying on both income-based and a sales-based metrics. Outside the U.S., the fraction is lower but has been growing. Multinational firms are exposed to additional risks beyond those facing domestic firms coming from political factors and exchange rates. However, they are likely to benefit from diversification of cash flows and flexibility in capital sources. We show that multinational firms, indeed, have a better access to foreign capital markets and a lower cost of debt than otherwise identical domestic firms, but the evidence on the cost of equity is mixed.
全球越来越多的公司在多个国家开展业务。我们研究了跨国公司在公司财务决策中的成本和收益,并调查了相关的学术证据。我们证明,在美国上市公司中,跨国公司的盛行程度与国内公司大致相同,使用基于收入和基于销售的指标的分类方案。在美国以外的地区,这一比例较低,但一直在增长。除了国内企业面临的风险外,跨国公司还面临来自政治因素和汇率的额外风险。不过,它们可能受益于现金流的多样化和资本来源的灵活性。我们表明,跨国公司确实比其他方面相同的国内公司有更好的进入外国资本市场的机会和更低的债务成本,但关于股本成本的证据是混合的。

We show that multinational firms, indeed, have a better access to foreign capital markets and a lower cost of debt than otherwise identical domestic firms, but the evidence on the cost of equity is mixed.","PeriodicalId":375725,"journal":{"name":"SPGMI: Capital IQ Data (Topic)","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115970133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show a long-lasting association between a common societal phenomenon, early-life family disruption, and investment behavior. Fund managers who experienced the death or divorce of their parents during childhood take lower risk and are more likely to sell their holdings following riskincreasing firm events. They make smaller tracking errors, hold fewer lottery stocks, and show a stronger disposition effect. The results strengthen as treatment intensifies, i.e., when disruption occurred during formative years, when bereaved families had less social support, and after (unexpected) parental deaths. The evidence adds to our understanding of the role of social factors and "nurture" in finance.
我们展示了一种常见的社会现象、早期家庭破裂和投资行为之间的长期联系。在童年时期经历过父母死亡或离婚的基金经理承担的风险较低,更有可能在风险增加的公司事件发生后出售所持股票。他们的跟踪误差较小,持有较少的彩票股票,并且表现出更强的处置效应。结果随着治疗的加强而加强,即,当在成长期发生破坏时,当失去亲人的家庭得到较少的社会支持时,以及在父母(意外)死亡后。这些证据增加了我们对社会因素和“教养”在金融中的作用的理解。
