We examine the use of foreign currency hedging instruments by US manufacturing firms during 1996–2004, and assess their impact on the firms' risk of financial distress. We derive measures of financial distress using the Black–Scholes–Merton option pricing model and find that the use of foreign currency hedging instruments reduces the firms' financial distress. The main findings are confirmed when examining alternate measures of foreign currency exposure, econometric specifications or measures of financial distress.
我们研究了1996-2004年期间美国制造业企业使用外汇对冲工具的情况,并评估了它们对企业财务困境风险的影响。我们使用Black-Scholes-Merton期权定价模型推导出财务困境的度量,并发现使用外币对冲工具减少了公司的财务困境。在考察外汇风险敞口、计量经济指标或财务困境的替代措施时,主要发现得到了证实。

The aim of this paper is to comprehensively compare option-based measures of volatility, with the ultimate plan of devising a new volatility index for the Italian stock market. The performance of the different implied volatility measures in forecasting future volatility is evaluated both in a statistical and in an economic setting. The properties of the implied volatility measures are also explored, by looking at both the contemporaneous relationship between implied volatility changes and market returns and the usefulness of the proposed index in forecasting future market returns.The results of the paper are of practical importance for both policy-makers and investors. The volatility index, based on corridor measures, could be used to forecast market volatility, for value at risk purposes, in order to determine trading strategies on the underlying index and as an early warning for future market conditions.
本文的目的是全面比较基于期权的波动率指标,最终计划为意大利股市设计一个新的波动率指数。不同的隐含波动率指标在预测未来波动率方面的表现分别在统计和经济环境中进行了评估。通过观察隐含波动率变化与市场回报之间的同期关系以及所提出的指数在预测未来市场回报方面的有用性,还探讨了隐含波动率指标的性质。本文的研究结果对政策制定者和投资者都具有重要的现实意义。基于走廊措施的波动率指数可用于预测市场波动率,用于风险价值的目的,以便确定基础指数的交易策略,并作为未来市场状况的早期预警。

In recent years, increasing effort has been devoted to the study of virtual world economies due to their potential of increasing our understanding of the real world economy, and vice versa. Due to a scarce availability of reliable global data, previous virtual world economic studies have been largely limited to qualitative observations. This paper presents novel financial data and is the first to apply a time series approach to the forecasting of virtual commodity prices. The results are assessed against the random walk and, from an efficient markets perspective, evaluates the potential of virtual worlds becoming experimental simulations for the real.
近年来,越来越多的人致力于虚拟世界经济的研究,因为它们有可能增加我们对现实世界经济的理解,反之亦然。由于缺乏可靠的全球数据,以往的虚拟世界经济研究在很大程度上局限于定性观察。本文提出了新颖的金融数据,并首次将时间序列方法应用于虚拟商品价格的预测。从有效市场的角度出发,评估了虚拟世界成为真实世界实验模拟的潜力。

What is the (Real Option) Value of a College Degree 大学学位的(实物期权)价值是什么
IF 0.7 Q3 BUSINESS, FINANCE Pub Date : 2013-09-01 DOI: 10.1142/S2010139213500158

The value of a college degree is often quantified as the difference in earnings between those with and without a degree. The research presented here operationalizes this idea in two important ways. First, since future income and tuition are uncertain, a contingent claims model is developed and the appropriate discount rate for valuing future earnings is, therefore, endogenized given an economy that does not permit arbitrage. Second, the model is sensitive to the valuation of the real option to obtain an advanced degree in addition to the valuation of the earnings for an individual with an undergraduate degree. In this framework, the value of a high school diploma is shown to be the sum of: (1) capitalized earnings, (2) the real option to obtain an undergraduate degree and (3) the embedded or compound real option to obtain an advanced degree. Numerical examples are presented that demonstrate the performance and key drivers of the model. One important finding is that by ignoring the real options to further one's education, the value of a college degree is likely significantly understated.
大学学位的价值通常被量化为有学位和没有学位的人之间的收入差异。这里提出的研究在两个重要方面实现了这一想法。首先,由于未来收入和学费是不确定的,因此开发了一个或有债权模型,因此,在不允许套利的经济中,评估未来收益的适当贴现率是内生的。其次,该模型除了对本科学历个体的收益估值敏感外,还对获得高学历的实物期权估值敏感。在这个框架中,高中文凭的价值显示为:(1)资本化收入,(2)获得本科学位的实物期权和(3)获得高级学位的嵌入或复合实物期权的总和。给出了数值算例,说明了该模型的性能和关键驱动因素。一个重要的发现是,如果忽视了进一步接受教育的实际选择,大学学位的价值可能会被大大低估。

Abnormal Profit Opportunities and the Informational Advantage of High Frequency Trading 异常盈利机会与高频交易的信息优势
IF 0.7 Q3 BUSINESS, FINANCE Pub Date : 2013-06-01 DOI: 10.1142/S2010139213500122
R. Jarrow, Hao Li
In a frictionless and competitive economy, where high frequency (HF) traders possess no market power, this paper characterizes necessary and sufficient conditions on the price process and information sets for HF traders to earn abnormal trading profits. Two sufficient conditions shown to generate abnormal returns are that HF trading enables the observation of short-term price momentum/reversals, not otherwise visible, or it enables the observation of signals correlated to future price movements. The welfare considerations of the existence of such abnormal trading profits are also discussed.
在无摩擦竞争经济中,高频交易者不具备市场支配力,本文刻画了高频交易者获取异常交易利润的价格过程和信息集的充分必要条件。产生异常回报的两个充分条件是高频交易可以观察到短期价格动量/反转,否则是看不见的,或者它可以观察到与未来价格走势相关的信号。本文还讨论了这种异常交易利润存在的福利考虑。

Bankruptcy Section 363 Sales: Choices and Consequences 破产法第363条:销售:选择和后果
IF 0.7 Q3 BUSINESS, FINANCE Pub Date : 2012-12-01 DOI: 10.1142/S2010139212500164

We contrast bankruptcy Section 363 Sales with the traditional path of Chapter 11 reorganization and find that among financial institutions, higher measures of creditors' coordination problems favor the Chapter 11 path, while greater profitability, available cash, asymmetric information between shareholders and creditors, and potential growth rate support the choice of 363 Sales. Among the non-financial firms, higher measures of creditors' coordination problem and available cash favor the course of Chapter 11, while greater profitability, liquidity, and asymmetric information support the path of 363 Sales. We further detect that bankruptcy Section 363 Sales exhibits lower direct fees, and it lasts significantly less time than formal Chapter 11 before the final emergence.
我们将363条款出售与传统的第11章重组路径进行对比,发现在金融机构中,债权人协调问题较高的指标倾向于第11章重组路径,而更大的盈利能力、可用现金、股东与债权人之间的信息不对称和潜在增长率支持363条款出售的选择。在非金融企业中,较高的债权人协调问题和可用现金指标有利于第11章的路径,而较高的盈利能力、流动性和信息不对称指标支持363销售路径。我们进一步发现,破产条款363销售显示出较低的直接费用,并且在最终出现之前持续的时间明显少于正式的第11章。

Filtering Out Expected Dividends and Expected Returns 过滤掉预期股息和预期回报

O. Rytchkov
This paper applies a state space approach to the analysis of stock return predictability. It acknowledges that expected returns and expected dividends are unobservable and uses the Kalman filter to extract them from the observed history of realized dividends and returns. The suggested approach explicitly takes into account the time variation in expected dividend growth rates and exploits the present value relation. The obtained predictors for future returns are robust to structural breaks in the means of expected dividends and returns and more efficient than the dividend–price ratio. The likelihood ratio test reliably rejects the hypothesis of constant expected returns.
本文将状态空间方法应用于股票收益可预测性分析。它承认预期收益和预期股息是不可观察的,并使用卡尔曼滤波器从观察到的已实现股息和回报的历史中提取它们。建议的方法明确考虑了预期股息增长率的时间变化,并利用了现值关系。所得的未来收益预测因子对预期股息和收益的结构性断裂具有鲁棒性,并且比股息价格比更有效。似然比检验可靠地拒绝了期望收益不变的假设。

Estimation of Dynamic Term Structure Models 动态期限结构模型的估计

We study the finite-sample properties of some of the standard techniques used to estimate modern term structure models. For sample sizes and models similar to those used in most empirical work, we reach three surprising conclusions. First, while maximum likelihood works well for simple models, it produces strongly biased parameter estimates when the model includes a flexible specification of the dynamics of interest rate risk. Second, despite having the same asymptotic efficiency as maximum likelihood, the small-sample performance of Efficient Method of Moments (a commonly used method for estimating complicated models) is unacceptable even in the simplest term structure settings. Third, the linearized Kalman filter is a tractable and reasonably accurate estimation technique, which we recommend in settings where maximum likelihood is impractical.
我们研究了一些用于估计现代期限结构模型的标准技术的有限样本性质。对于与大多数实证工作中使用的相似的样本量和模型,我们得出了三个惊人的结论。首先,虽然最大似然对简单模型很有效,但当模型包含利率风险动态的灵活规范时,它会产生强烈的偏差参数估计。其次,尽管具有与最大似然相同的渐近效率,但即使在最简单的期限结构设置中,有效矩量法(一种用于估计复杂模型的常用方法)的小样本性能也是不可接受的。第三,线性化卡尔曼滤波是一种易于处理且相当准确的估计技术,我们推荐在最大似然不切实际的情况下使用。

The Importance of Angel Investing in Financing the Growth of Entrepreneurial Ventures 天使投资对创业企业成长融资的重要性
IF 0.7 Q3 BUSINESS, FINANCE Pub Date : 2012-10-01 DOI: 10.1142/S2010139212500097

Investigation of the role of angel investing in financing private businesses in the US is important. Many observers consider angel investments to be one of the key drivers behind the startup and growth of new businesses (Council on Competitiveness, 2007), despite a paucity of information to confirm whether or not this is true. Unlike venture capital investments, angel investments are made by individual investors who do not make up a known population. Therefore, much of what is reported about angel investing comes from anecdotes and surveys of convenience samples, which are prone to biases and inaccuracies. Moreover, research on this topic is plagued by definitional confusion, in which different investigators confound informal investors, friends and family who invest in startups, accredited and unaccredited angel investors, and individual and group investing; this confusion makes it difficult to compare findings across studies. This report seeks to provide an accurate understanding of the role of angel investing in the entrepreneurial finance system. It defines angel investing and reviews the current state of understanding of the phenomenon, focusing on answering four questions: (1) How large is the angel capital market? (2) How much demand is there for angel capital? (3) What are the primary characteristics of angel investments? (4) What do the companies that receive angel financing look like? It answers these questions by reviewing the literature, providing a statistical evaluation of data sources drawn from representative samples of known populations, examining new non-representative surveys of angel investors, and comparing the results of these new analyses to previous studies of non-representative samples of business angels.
研究天使投资在美国私营企业融资中的作用是很重要的。许多观察家认为天使投资是新企业启动和成长背后的关键驱动因素之一(竞争力委员会,2007),尽管缺乏信息来证实这是否属实。与风险资本投资不同,天使投资是由个人投资者进行的,他们并不构成已知的人群。因此,关于天使投资的报道大多来自于轶事和便利样本的调查,这容易产生偏见和不准确。此外,关于这一主题的研究还受到定义混乱的困扰,不同的研究者将非正式投资者、投资初创企业的朋友和家人、认可的和未认可的天使投资者、个人和团体投资混为一谈;这种混淆使得比较不同研究的结果变得困难。本报告旨在准确理解天使投资在创业融资体系中的作用。它定义了天使投资,并回顾了目前对这一现象的理解状况,重点回答了四个问题:(1)天使资本市场有多大?(2)对天使资本的需求有多大?(3)天使投资的主要特征是什么?(4)获得天使融资的公司是什么样的?本文通过回顾文献来回答这些问题,对从已知人群的代表性样本中提取的数据源进行统计评估,检查新的天使投资者非代表性调查,并将这些新分析的结果与之前对商业天使非代表性样本的研究进行比较。

How to Reform the Credit-Rating Process to Support a Sustainable Revival of Private-Label Securitization ¤ 如何改革信用评级程序以支持自有品牌证券化的可持续复兴
IF 0.7 Q3 BUSINESS, FINANCE Pub Date : 2012-07-25 DOI: 10.1142/S2010139212500024

US product-liability laws unwisely treat credit-rating organizations (CROs) as if they produce opinions rather than empirically-based economic research. In principle, trained professionals gather time-varying information ("financial news") and analyze it statistically to reduce it to a single dimension, allegedly for the benefit of investors, which, in turn, enables issuers to finance themselves at lower cost. In practice, the issuer-pays business model currently used for funding the production and distribution of ratings information creates an incentive to favor high-volume issuers by over-rating private-label securitizations. While the Dodd–Frank Act intensifies SEC oversight of CRO activity, the SEC has a history of being captured by regulatory clients. We argue that the fundamental solution is to create accountability in the ratings process so that private label securitizations can play a constructive role in the provision of credit and we go on to offer some conjectures about how this could be done.
美国产品责任法不明智地将信用评级机构(cro)视为发表意见,而不是基于经验的经济研究。原则上,训练有素的专业人员收集时变信息(“金融新闻”),并对其进行统计分析,将其减少到单一维度,据称是为了投资者的利益,这反过来又使发行人能够以更低的成本为自己融资。在实践中,目前用于为评级信息的制作和分发提供资金的“发行者付费”商业模式,会通过对自有品牌证券的过高评级来鼓励大量发行者。虽然《多德-弗兰克法案》(Dodd-Frank Act)加强了SEC对CRO活动的监督,但SEC向来有被监管机构客户俘获的历史。我们认为,根本的解决方案是在评级过程中建立问责制,使自有品牌证券化在提供信贷方面发挥建设性作用,我们继续就如何做到这一点提出一些猜想。

In principle, trained professionals gather time-varying information (\"financial news\") and analyze it statistically to reduce it to a single dimension, allegedly for the benefit of investors, which, in turn, enables issuers to finance themselves at lower cost. In practice, the issuer-pays business model currently used for funding the production and distribution of ratings information creates an incentive to favor high-volume issuers by over-rating private-label securitizations. While the Dodd–Frank Act intensifies SEC oversight of CRO activity, the SEC has a history of being captured by regulatory clients. We argue that the fundamental solution is to create accountability in the ratings process so that private label securitizations can play a constructive role in the provision of credit and we go on to offer some conjectures about how this could be done.","PeriodicalId":45339,"journal":{"name":"Quarterly Journal of Finance","volume":"20 1","pages":"1250002"},"PeriodicalIF":0.7,"publicationDate":"2012-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88737717","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}
