In this thesis, we study basket options which are contracts on N assets. It is known that the risk neutral joint probability density of the assets is uniquely defined by the prices of basket options with positive weights. However, the proof of this fact requires a step involving the inversion of a Laplace transform. It is known that inversion of a Laplace transform is a severely ill-posed problem. The purpose of this thesis is to understand whether inversion of the basket transform is ill-posed or not.In our dissertation, we propose three methods to determine and prove the order of ill-posedness for the case when the basket contains only one asset and then map the problem to Radon transform to address two or higher dimensional case. Our proofs show that that problem is mildly ill-posed of order 1/2 (N -1) 2 given N dimensions.We also conduct numerical experiments under the Black-Scholes setting. First, using the reconstruction method from Cohen and Pagliacci, our results show that this method functions well in one-dimension but it becomes numerically intensive in our two-dimensional implementation, and we were unable to achieve convergence. Alternatively, we have looked at using an inverse Radon transform method to reconstruct the joint density numerically. As this requires knowledge of basket prices with negative weights, we have tried extending the basket price in this region as an odd function. For comparison, we compared this against the reconstruction from approximate basket prices calculated directly in the negative weight region. It is fascinating that these two approaches give similar results. This may indicate that the errors are due to the two-moment matching approximation rather than the odd extension. This intriguing possibility would certainly merit further investigation if more time were available.We believe that our mathematical particularly, but also our numerical results indicate there is cause for optimism that a stable numerical algorithm to reconstruct the joint density function from basket prices will be found in the future.
在本文中,我们研究了N种资产合约的篮子期权。已知资产的风险中性联合概率密度是由正权重的一篮子期权价格唯一定义的。然而,这个事实的证明需要一个涉及拉普拉斯变换逆的步骤。众所周知,拉普拉斯变换的反演是一个严重不适定的问题。本文的目的是了解篮变换的反演是否是病态的。在本文中,我们提出了三种方法来确定和证明当篮子中只有一个资产时的不适定性顺序,然后将问题映射到Radon变换来解决二维或高维情况。我们的证明表明,在N维条件下,这个问题是1/2 (N -1) 2阶的轻度病态。我们还在Black-Scholes设置下进行了数值实验。首先,使用Cohen和Pagliacci的重建方法,我们的结果表明,该方法在一维中运行良好,但在二维实现中它变得数字密集,并且我们无法实现收敛。另外,我们还研究了使用反Radon变换方法在数值上重建关节密度。由于这需要了解负权重的篮子价格,我们尝试将该区域的篮子价格扩展为奇函数。为了进行比较,我们将其与直接在负权重区域计算的近似篮子价格的重建进行了比较。令人着迷的是,这两种方法给出了相似的结果。这可能表明误差是由于两矩匹配近似而不是奇数扩展引起的。如果有更多的时间,这种有趣的可能性肯定值得进一步调查。我们相信,我们的数学结果,特别是我们的数值结果表明,有理由乐观地认为,一个稳定的数值算法重建联合密度函数从篮子价格将在未来被发现。

The Intellectual Capital and the Relevance of Non-Financial Information About Innovation in the Spanish Automotive Sector from an Accounting Perspective: A Proposal of an Indicator 会计视角下西班牙汽车行业创新的智力资本与非财务信息的相关性:一个指标的建议

Our research on the relevance of non-financial information considers to aspects: one that requires more complete and adequate information on intangibles or Intellectual Capital (IC); and another concerned with the today’s main accounting conceptual frameworks, to which a certain rigidness is attributed in terms of recognizing intangibles in financial areas that can lead to the financial information not being useful for those who use it. Given the complexity of IC, we concentrate on the information provided on websites of automobile component manufacturers in the Spanish automotive sector. We’ve designed an indicator for the innovation disclosure intensity (I3) and a classification of the activities carried out by these companies (UFPE). Both items are crossed with the ratio ROA and Cash-Flow from total assets (Self-financing Capacity). We found statistically significant evidence that companies with lower I3 have worse ROA and Self-financing Capacity ratios.
我们对非财务信息相关性的研究考虑了以下几个方面:一是需要更完整和充分的无形资产或智力资本(IC)信息;另一个与当今主要的会计概念框架有关,在识别财务领域的无形资产方面,它具有一定的刚性,这可能导致财务信息对那些使用它的人没有用处。鉴于集成电路的复杂性,我们专注于西班牙汽车行业汽车零部件制造商网站上提供的信息。我们设计了创新披露强度指标(I3)和企业创新活动分类(UFPE)。这两个项目都与总资产的总资产收益率和现金流量比率(自筹资金能力)相交叉。我们发现具有统计学意义的证据表明,I3较低的公司ROA和自筹资金能力比率较差。

The Role of Industry Classification in the Estimation of Research and Development Expenditures 行业分类在研发支出估算中的作用
Pub Date : 2014-08-26 DOI: 10.2139/ssrn.2527174

This paper uses data from the National Science Foundation’s surveys on business research and development (R&D) expenditures that have been linked with data from the Census Bureau’s Longitudinal Business Database to produce consistent NAICS-based R&D time-series data based on the main product produced by the firm for 1976 to 2008.The results show that R&D spending has shifted away from domestic manufacturing industries in recent years. This is due in part to a shift in U.S. payrolls away from manufacturing establishments for R&D-performing firms.These findings support the notion of an increasingly fragmented production system for R&D-intensive manufacturing firms, whereby U.S. firms control output and provide intellectual property inputs in the form of R&D, but production takes place outside of the firms' U.S. establishments.
本文使用了美国国家科学基金会关于企业研发支出的调查数据,这些数据与人口普查局纵向商业数据库的数据相关联,以1976年至2008年企业生产的主要产品为基础,得出了一致的基于naics的研发时间序列数据。研究结果表明,近年来,研发支出逐渐从国内制造业转移。这在一定程度上是由于美国的就业岗位从制造业转向研发型企业。这些发现支持了研发密集型制造企业生产系统日益碎片化的观点,即美国公司控制产出,并以研发的形式提供知识产权投入,但生产发生在公司的美国机构之外。

The Bornhuetter-Ferguson (BF) reserve of an accident year is the product of an a priori estimate of the expected ultimate claim and the estimated 'still to come percentage'. In practice, these a priori estimates are often adjusted over time. We call this process 'repricing'. In this paper we study the incorporation of claims experience for the repricing process by using credibility theory. We simultaneously estimate the still to come percentages and we quantify the prediction uncertainty of the resulting reserves. In a special case the method can be interpreted as a weighted average between chain ladder (CL) and BF.
事故年的bornhutter - ferguson (BF)准备金是对预期最终索赔的先验估计和估计的“尚未发生的百分比”的乘积。在实践中,这些先验估计经常随着时间的推移而调整。我们称这个过程为“重新定价”。本文运用可信性理论,研究了在定价过程中引入索赔经验的问题。我们同时估计了未来的百分比,并量化了最终储量的预测不确定性。在特殊情况下,该方法可以解释为链梯(CL)和BF之间的加权平均。

Internet Measurements and Public Policy: Mind the Gap 互联网测量和公共政策:注意差距
Pub Date : 2013-12-31 DOI: 10.2139/ssrn.2294456
H. Asghari, M. V. Eeten, Milton L. Mueller
Large and impressive data collection efforts often fail to make their data useful for answering policy questions. In this paper, we argue that this is due to a systematic gap between the ways measurement engineers think about their data, and how other disciplines typically make use of data. We recap our own efforts to use the data generated by a number of such projects to address questions of Internet and telecommunication policy, and based on our experience, propose five points for engineers to consider when building measurement systems to reduce the gap. Ignoring the gap means that fewer researchers use the data and significantly lowers a project’s impact on policy debates and outcomes.
庞大而令人印象深刻的数据收集工作往往无法使其数据对回答政策问题有用。在本文中,我们认为这是由于测量工程师思考数据的方式与其他学科通常如何利用数据之间的系统差距。我们回顾了我们自己的努力,利用一些这样的项目产生的数据来解决互联网和电信政策的问题,并根据我们的经验,提出了五个要点,供工程师在建立测量系统时考虑,以减少差距。忽略这一差距意味着更少的研究人员使用这些数据,并大大降低了一个项目对政策辩论和结果的影响。

Purpose – During the last decade, intellectual capital (IC) has been widely considered as a critical tool to deliver successful business in an intensive knowledge environment. The main goal of this paper is therefore to develop and prioritize human capital indicators as an important component of IC in knowledge-based industries.Design/methodology/approach – Based on an extensive literature review, a valid and reliable questionnaire was designed. In order to data gathering, it was sent out to 108 participants from academic and university who qualified well in pharmaceutical practice. Besides statistical analysis, we also used fuzzy TOPSIS technique as a MADM model in order to exact prioritization of indicators. Findings – The analysis indicates that there is little difference between academic and university respondents. Furthermore, the fuzzy TOPSIS results show that participants remark high concerns especially about knowledge and skills of managers and employees.Research limitations/implications – The findings offer valuable insights in order to evaluation of human capital state as a key component of IC in knowledge-based industry.Practical implications – There is an immediate need that the policy makers and corporate managers wake up to the need and start to measure and disclosure the intangible assets of firms. Intellectual capital measurement is of primary interest for top executives of pharmaceutical firms in Iran as well.Originality/value – This is an initial and pioneering study to develop a valid tool to evaluate IC in Iranian pharmaceutical industry. The present study provides a new aspect of performance measurement for research-based industries in emerging economies and would be a good topic for further research.
目的——在过去的十年中,智力资本(IC)被广泛认为是在密集的知识环境中交付成功业务的关键工具。因此,本文的主要目标是开发和优先考虑人力资本指标,作为知识型产业集成电路的重要组成部分。设计/方法/方法-基于广泛的文献回顾,设计了一个有效和可靠的问卷。为了收集数据,将其发送给108名来自学术和大学的参与者,他们在制药实践中具有良好的资格。除了统计分析外,我们还使用模糊TOPSIS技术作为MADM模型,以精确确定指标的优先级。调查结果-分析表明,学术和大学受访者之间的差异不大。此外,模糊TOPSIS结果表明,参与者对管理者和员工的知识和技能尤其关注。研究局限性/启示-研究结果为评估人力资本状态作为知识型产业集成的关键组成部分提供了有价值的见解。实际影响-政策制定者和公司管理者迫切需要意识到需要并开始衡量和披露公司的无形资产。智力资本测量也是伊朗制药公司高管的主要兴趣所在。原创性/价值——这是一项初步的开创性研究,旨在开发一种有效的工具来评估伊朗制药行业的IC。本研究为新兴经济体研究型产业的绩效评估提供了一个新的视角,是一个值得进一步研究的课题。

Measuring National Innovation Systems Efficiency – A Review of DEA Approach 衡量国家创新体系的效率--DEA 方法评述
Pub Date : 2013-08-01 DOI: 10.2139/ssrn.2304735
M. Kotsemir
The paper reviews the application of the data envelopment analysis (DEA) method for measuring the efficiency of national innovation systems (NIS). The paper firstly visualizes the logic of DEA method and briefly summarizes the key advantages and main limitations of the DEA method. Further, this paper provides a comprehensive review of 11 empirical studies on cross-country analysis of NIS efficiency with DEA technique. In its main part the paper analyses the specifications of DEA models used in the reviewed studies, the content of the country samples, sets of input and output variables used and the resulting lists of efficient countries. The review detects general trends and differences in the sets of variables and the content of country samples. Moreover, this paper highlights the problem of “small countries bias” in the reviewed studies: situation when “small” (in terms of national innovation system scope and the level of development) countries (like Venezuela, Kyrgyzstan etc.) are included in the country sample, these “small” countries become the efficient ones. In general, empirical studies on cross-country analysis of national innovation systems efficiency using DEA method pay little attention to profound analysis of previous relevant studies. Therefore, this paper is among the first papers with deep review of such empirical studies
本文回顾了数据包络分析法(DEA)在衡量国家创新体系(NIS)效率方面的应用。本文首先直观地介绍了 DEA 方法的逻辑,并简要总结了 DEA 方法的主要优势和局限性。此外,本文还全面回顾了利用 DEA 技术对国家创新体系效率进行跨国分析的 11 项实证研究。本文的主要部分分析了所综述研究中使用的 DEA 模型的规格、国家样本的内容、所使用的投入和产出变量集以及由此得出的高效率国家名单。审查发现了变量集和国家样本内容的一般趋势和差异。此外,本文还强调了综述研究中的 "小国偏差 "问题:当 "小 "国家(就国家创新体系范围和发展水平而言)(如委内瑞拉、吉尔吉斯斯坦等)被纳入国家样本时,这些 "小 "国家就会成为高效国家。一般来说,利用 DEA 方法对国家创新系统效率进行跨国分析的实证研究很少关注对以往相关研究的深刻分析。因此,本文是首批对此类实证研究进行深入评述的论文之一。

Innovation Analysis 创新分析
Pub Date : 2013-05-19 DOI: 10.2139/ssrn.2266998
Paul I. Louangrath
The purpose of this paper is to define innovation and to proffer evidence of its existence through the use of statistical method and mathematical modeling. Innovation is defined by the confidence interval of the normal probability distribution density where μ ± 2σ = 0.95 leaving a room of ±α = 0.05 for randomness. This paper claims that the upper tail of the probability distribution density curve ( α = 0.025) is an area of focus for innovation analysis. The lower tail of the curve: −α = −0.025 is a random area that is not a subject of innovation analysis. The paper employs series of tests to determine and verify innovation. Two situations are presented. On the one hand, innovation is tested by comparing the claimed output change against the industry referenced mean. On the other, innovation may also be proven where there is no external reference. Vouching and tracing analyses are used where there is an industry reference indicator.

本文的目的是通过使用统计方法和数学建模来定义创新并提供其存在的证据。创新定义为正态概率分布密度的置信区间,其中μ±2σ = 0.95,随机系数为±α = 0.05。本文认为概率分布密度曲线的上尾(α = 0.025)是创新分析的重点区域。曲线的下尾:−α =−0.025是一个随机区域,不是创新分析的主题。本文采用一系列的测试来确定和验证创新。提出了两种情况。一方面,通过将声称的产出变化与行业参考平均值进行比较来检验创新。另一方面,创新也可以在没有外部参考的地方得到证明。在有行业参考指标的地方使用凭证和跟踪分析。如果没有这样的外部参考指标,则使用Dixon异常值检验。

This paper claims that the upper tail of the probability distribution density curve ( α = 0.025) is an area of focus for innovation analysis. The lower tail of the curve: −α = −0.025 is a random area that is not a subject of innovation analysis. The paper employs series of tests to determine and verify innovation. Two situations are presented. On the one hand, innovation is tested by comparing the claimed output change against the industry referenced mean. On the other, innovation may also be proven where there is no external reference. Vouching and tracing analyses are used where there is an industry reference indicator. Absent such an external reference indicator, the Dixon outliers test is used.","PeriodicalId":346559,"journal":{"name":"Innovation Measurement & Indicators eJournal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129401052","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}

In the knowledge economy intangible resources are the primary value drivers. This is particularly true of companies such as banks. However, intangible resources (Intellectual Capital) appear difficult to measure. Today, there are several methods that allows to measure Intellectual Capital in listed companies. However, not all methods of measurement are adequate for listed banks. The paper uses the KCE™ (Knowledge Capital Earnings™) ratio, to measure the Intellectual Capital efficiency of the Polish listed banks in the peer group. The time horizon was set for the period due to the possibility of recognition of years in which banks recorded a higher income and years in which recorded a drop in revenue caused by the subprime crisis in financial markets (2005-2011). The results extend the role of understanding of the Intellectual Capital in creation of sustainable advantages for banks in developing economies.
在知识经济中,无形资源是主要的价值驱动因素。银行等公司尤其如此。然而,无形资源(智力资本)似乎难以衡量。今天,有几种方法可以衡量上市公司的智力资本。然而,并非所有的计量方法都适用于上市银行。本文采用知识资本收益比率(KCE™)来衡量波兰上市银行在同行组中的知识资本效率。由于有可能确认银行记录较高收入的年份和由于金融市场次贷危机(2005-2011)而记录收入下降的年份,因此为这一时期设定了时间范围。研究结果扩展了理解智力资本在为发展中经济体的银行创造可持续优势方面的作用。
