股指期货对股票价格指数波动性影响——对日经225指数的实证分析

中国正在酝酿推出股指期货,而对股指期货的推出会对股票现货市场波动性产生影响至今没有定论.因此选择与我国样A股本标准差最接近的日经225指数为分析样本,采用加入虚拟变量的GARCH模型进行实证研究,通过对比日本证券市场在推出日经225股指期货前后,股市整体的波动性是否有明显改变进行实证分析,得出股指期货的推出有效地降低了日本股市波动性的结论,从而绐中国推出股指期货交易提供理论支持.     

股指期货推出对现货市场走势的影响

部分市场人士和投资者担心,股指期货的推出将会成为现货市场做空的动因,从而导致中国股市出现大幅震荡和下跌,即所谓的股指期货行情命题。笔者认为,只有结合一个国家或地区的经济社会发展阶段、经济金融背景,在充分估计非股指期货因素对特定现货市场的影响之后,才能够相对客观和准确地把握股指期货推出对现货市场走势产生的实际影响。

股指期货利弊

推出股指期货的主要目的是给市场带来高效的定价机制,以消除过度投机,维护市场稳定。金融衍生产品能否被市场高效合理地定价,是市场是否健康的重要标志。股指期货做为20世纪80年代国际金融市场上最为重要的金融创新,目前已经是世界上交易量和流动性最好的金融衍生产品之一,被公认为是股市上最为有效的风险管理工具之一。推出股指期货对市场的     

股指期货对股票市场的波动性影响

2006年10月23日,中国金融期货交易所公布了《沪深300指数期货合约》、《交易细则》、《结算细则》和《风险控制管理办法(征求意见稿)》四个征求意见稿,表明我国股指期货推出进入倒计时。本文研究股指期货对现货市场产生的影响,通过研究分析我国周边国家或地区股指期货对现货市场的长期与短期波动性,并为预测分析我国股指期货推出后现货市场走势提供参考。本文从两个方面进行分析研究,一是通过选取中国台湾加权股价指数、日经225指数、马来西亚KLSE Composite、印度BSE30为标的物的股指期货推出前后两年现货股价指数走势为样本,分析其股指期货推出前后股价指数走势;二是利用印度BSE30指数的数据对印度股票市场进行实证研究,希望对我国股指期货市场建设有所借鉴。一、实证研究1.股指期货推出前后股价指数走势研究中金公司即将推出以沪深300指数为标的物的首个股指期货合约。因为股指期货在我国还属于新生事物,对其制定和操作没有相关的经验,加之我国证券市场有其自身特征,所以不能完全借鉴其他国家和地区的模式,但考察其他国家或地区股指期货设立之初其标的物指数波动情况,将有助于我国推出股指期货的市场预期。本文选择了中国台湾加权股价指数...     

股指期货与股票市场定价效率问题

股指期货的推出,大大提高了股票市场的定价效率.在无套利均衡市场上,股指期货价格由相关股票组合的价格及持有成本决定,股票现货价格成为影响股指期货价格的主要因素.但在动态非均衡市场上,股指期货的价格形成集中并传递大量信息,这些信息通过股指期货市场与股票市场间的套利机制及时传递到股票市场,增加相关股票组合价格的信息含量,引导和发现现货价格,从而提高股市的定价效率.     

股指期货对股票现货市场的影响

从整体上来看,股指期货市场和股票现货市场两市形成了"血肉相联"和"领先—滞后"的关系。从股指期货的推出到现在来看,它的影响是双面的,在我们手中如同一把"双刃剑",只有正确认识股市期货的积极以及消极作用,才能切实采取措施实现期货市场和股票现货的共同繁荣。     

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.     

Commodity financialization and sector ETFs: Evidence from crude oil futures

We investigate the diversification benefits of energy assets in the setting of commodity financialization using data on crude oil futures and Sector ETFs (SPDRs). Correlations between commodities and financial assets increased during the post-Commodity Futures Modernization Act (CFMA)/commodity bull cycle period, resulting in lower benefits of diversification. However, we find that conditional correlations between crude oil futures and sector ETFs meaningfully increased only since the 2008–09 financial crisis. The results therefore suggest that the financial crisis, rather than CFMA regulation, explains changes in the diversification benefits of commodities. Moreover, we find that oil futures returns are less correlated with SPDRs than with the S&P index. Thus, energy futures, and crude oil in particular, offer the potential for diversification benefits in sector-style investing.     

Dutch accounting in Japan 1609-1850: isolation or observation?

The trading station or factory maintained by the Dutch East India Company (VOC) was Japan's sole window on the Western world during most of the Tokugawa period (1600-1868). While many aspects of the factory's role in Dutch/Japanese cultural exchange have been researched little is known in the West of the accounting at the factory. This paper considers the possibility that double-entry bookkeeping employed by the Dutch may have been diffused to the Japanese. The available evidence is synthesized after considering the accounting system in the Dutch factory.
