考虑流动性的三阶矩资本资产定价的理论模型与实证研究

本文把流动性风险、偏态风险引进传统CAPM模型中,推导出基于流动性的三阶矩资本资产定价的理论模型。本文的模型表明,证券(组合)的收益依赖于它的期望流动性成本、其流动性成本和市场流动性成本的协方差以及其收益和市场收益的协方差与协偏态。本文采用我国A股市场的股票收益数据对模型进行了实证检验.检验结果表明,我国A股市场的证券(组合)的风险溢价在大盘升降区间体现了不同的特征,无论是在全样本区间还是两个子样本区间,基于流动性的三阶矩资本资产定价模型都能更好的拟合资产收益,说明了流动性和偏态因素在我国A股市场的资产定价中有重要影响。     

轻制造型企业资产结构初探

<正>企业在资产负债表日的资产是企业自开业至资产负债表日以来的各项经济活动结果的综合体现,更是财务管理工作成效的体现。如果企业的财务管理及时、有效,那么体现在资产负债表上的资产结构则良好,反之,则不合理。如何分析、判断企业资产结构的合理性?本文拟首先分析轻制造型企业理想状态下的资产结构,然后选择我国A股20家家电上市公司的资产结构作为样本进行分析,最后将样本企业的资产结构与理想状态下的资产结构进行对比,分析、判断我国A股家电上市公司资产结构的合理性并提出相关建议。

基于PCC方法的Gaussian DAG-Copula模型的构建

本文基于PCC方法,介绍了一种新的构建高维Copula模型的图形化方法,即DAG-Copula 方法,该方法的优点主要有:降低模型估计的难度,提高模型估计的精度.以中国外汇市场上四种外汇收益率序列为研究对象,运用PC算法估计了DAG,建立了Gaussian DAG-Copula模型.作为对比,用四维t-Copula描述外汇资产的相关结构,通过对比发现Gaussian DAG-Copula模型能更好的描述资产间的相关结构.     

高速公路行业资产结构与绩效关系实证研究

<正>文章将EVA绩效评价指标与资产结构的研究相结合,以沪、深、港三市高速公路上市公司为样本,对高速公路行业资产结构与绩效的关系进行实证研究。研究结果表明,高速公路行业资产结构与绩效存在显著的关系,优化资产结构、提高资产利用效率是提高高速公路公司绩效的重要途径。一、研究背景资产结构是指企业各种类型资产的比例构成及由此形成的相互关系。绩效是指企业从事生产经营活动所取得的成绩或结果。资产结构与企业绩效是否相关?相关程度如何?怎样科学安排资金和资产,达到合理的资源配置,提高资产利用效率,最终改善企业绩效,是资产结构研究的主要目的。     

资产组合风险的极值Copula模型与实证研究

本文在极值理论POT模型的基础上,引入了Copula连接函数,建立极值Copula模型,给出了组合风险价值VaR的计算公式,并以加元和日元回报为样本进行了实证分析,结果表明,极值Copula模型能较好地度量资产组合的风险,直接加权的方法会高估风险,假设资产组合服从多元正态分布会低估风险。     

基于动态条件相关性的跨期资本定价实证研究

跨期资本资产模型提出了风险与收益之间的跨期关系,但是以往在证明跨期关系时普遍使用的是静态条件协方差。动态条件相关性模型能够描述时间序列间动态的相关性,利用动态条件相关性模型验证了跨期资本资产定价模型中的跨期关系,并且得到了资产组合收益率和这些因素间的动态条件协方差,然后测试这些协方差是否能够预测资产组合收益的时间序列变化。通过实证分析发现对于长样本和短样本来说,资产组合和市场组合之间的协方差对资产组合收益的影响是不同的。     

我国商业银行信用风险违约评估模型的实证分析

本文在分析指出国内对于转轨时期我国商业银行信用风险识别和违约评估方法研究所存在的主要缺陷基础上,构建了适用于我国商业银行的信用风险评估模型,并随机选取了能代表整体信贷资产特征的某商业银行1249个贷款样本资料,对模型的有效性进行了实证检验。结果证明本文所建立的模型在度量借款人信用风险方面具有稳定性和有效性。最后,本文对于我国商业银行使用信用风险内部评级法给出了相关政策建议。     

封闭式基金的投资风格的实证研究——以动态的视角

本文回顾了Sharpe(1992)的资产因子回归模型,并用于分析我国的封闭式基金的投资风格。研究发现,样本基金中实际投资风格偏离了宣称的投资风格,同一个基金投资风格前后不一致,而且样本基金存在着投资风格趋同的现象。而且通过动态的视角,说明了该模型被忽略的价值。     

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.

International harmonization of Japanese accounting standards

Historically, Japanese accounting standards have been quite distinct from International Accounting Standards (IASs) which have been perceived as being modelled on British-American accounting standards. However, in the 1990s, after the publication of E32 in 1989 and the IASC-IOSCO Agreement in 1995, the Business Accounting Deliberation Committee (BADC), the standards-setting body in Japan, has pursued a policy of harmonization with IASs. Accounting standards relating to consolidated financial statements of companies that make cross-border offerings of securities or operate worldwide are being revised drastically. This paper focuses on the development of international accounting harmonization and its impact on Japan.
