我国股市非线性特征的检验与分形验证

对我国股票市场的非线性特征进行分析,实证检验说明我国股票市场不服从传统理论假定的正态分布,呈现出＂尖峰＂和＂厚尾＂态势,股票市场的收益率具有持续性,存在长期记忆的分形特征,是一个复杂的非线性系统。     

股票市场与外汇市场收益率波动溢出效应研究——基于多元BEKK-GARCH模型

用多元BEKK-GARCH模型检验了股票市场与外汇市场收益率的波动溢出效应,结合LR似然比检验和Wald检验,实证研究股票市场和外汇市场收益率的波动关系。研究表明:股票市场与外汇市场收益率序列都存在ARCH效应和GARCH效应,即都具有时变方差特征;且两市的波动具有较高的持续性。股票市场和外汇市场收益率存在单向的,不对称的溢出效应,即汇市对股市有波动溢出效应,反之则不然。     

我国货币政策对股票市场收益率影响的实证研究

为检验我国货币政策对股票市场的有效性,本文在经典理论的基础上,运用协整检验、格兰杰因果检验、VECM检验方法,对货币政策与股票市场收益率关系进行实证分析。研究结果表明：货币供应量增长率与股票市场收益率呈正相关关系,但长期内影响效果不显著;利率的调整在短期内对股票收益率的影响较为显著,在长期内则表现为平稳,两者关系符合一般金融理论;进一步地,采用虚拟变量回归模型,分析了货币政策环境变化对收益率大小的影响。笔者根据我国的国情,分析这种传导效应的结果,做出了相应的判断,并对如何解决货币政策对股票市场传导中存在的问题提出了自己的看法。     

基于深圳股市的CAPM模型适用性检验

本文利用深圳股票市场近六年的股票周收益率对经典CAPM模型进行了实证检验,检验方法采用传统BJS检验法和F-M修正法。检验结果表明经典CAPM模型并不能很好的解释我国股票市场的表现。     

基于ARMA-EGARCH-M模型的深证股指研究

文章简要介绍了股票市场波动性研究的发展过程,并以2003年1月2日—2011年1月4日的深圳证券收盘价为样本,对我国深市收益率进行统计分析。对收益率序列ADF检验,自相关检验,发现收益率可用ARMA模型模拟。对ARMA模拟后的残差ARCH效应检验,发现我们可用ARMA-EGARCH-M模型拟合。再对两模型进行比较分析。     

我国上证A股指数收益波动性的研究

本文运用ARCH族模型对我国上证A股股指日收益率及波动性进行实证研究,探索我国A股股指收益率波动特征。实证研究结果发现:上证A股股指日收益率呈现明显的波动集群性特征,因此我国证券市场表现出的波动幅度和风险性要远远大大高于国外成熟的资本市场;我国股票市场存在显著的信息非对称性和杠杆效应,尤其是股票市场好消息导致的市场波动比同等大小的坏消息引起的波动要小。研究结果显示回归模型存在自回归条件异方差,这表明我国股票市场波动具有条件异方差效应。

我国股市的羊群效应的检验——基于上证50指数的研究

本文旨在用ARCH模型来检验股票市场的羊群效应。以上证50指数以及18个样本股的日收益率数据为研究对象,对2007年3月20日-2012年8月3日期间我国股票市场的羊群效应进行检验,得出股市在这段期间存在着羊群效应的结论。     

机构投资者与股价波动——以社保基金和QFII资金为例

本文在对A股指数及其收益率走势进行分析的基础上．采用非对称的GARCH模型拟合A股收益率的变动,然后对模型的稳健性进行了检验,最后得出结论,认为：以社保基金和QFII为代表的机构投资者进入股票市场能够有效地降低我国股票收益率的自相关性以及收益的波动性。     

货币政策与股票收益率的非线性影响机制研究

本文对股票收益率、货币政策以及产出之间的动态关系进行了线性检验,结果发现三者之间的动态调整过程存在明显的非线性特征。在此基础上构建了平滑迁移结构向量自回归模型(ST-SVAR)刻画三者之间的非线性关系,并计算了ST-SVAR模型的广义脉冲响应函数。结果发现货币政策对股票市场具有显著影响,并存在非对称性,即扩张性的货币政策对股票市场的拉动效应大于紧缩性的货币政策对股票市场的抑制效应。而产出与股票收益率之间的关系并不明显,股票收益率并不能完全反应经济基本面,存在一定程度的两分性。     

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.

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

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.
