论我国期货市场大豆价格发现功能的实证分析

价格发现功能是期货市场的基本功能之一,它在期货市场的发挥程度直接反映了期货市场的有效性.为检测我国农产品期货市场的价格发现能力,本文借助于单位根平稳性检验、协整检验,格兰杰因果关系检验等计量经济学方法对期货市场的价格发现功能进行了实证分析.研究结果显示,我国农产品期货市场的大豆期货价格与最后交割日的现货价格之间存在长期均衡关系,最后以大豆期货市场良好的价格发现功能和较完善的市场运行机制为契机,进一步提出完善我国农产品市场运行机制的相关政策建议.     

我国小麦和大豆期货市场价格发现功能的实证分析

期货市场以其价格发现功能而处于市场机制的核心地位,其价格信息为宏观决策和微观经济活动提供依据和参考.目前我国期货市场正步入新的发展期,研究期货市场上主要商品的价格发现功能情况具有重要意义.本文选取了我国商品期货市场上小麦和大豆两个期货品种的期货价格和现货价格数据,并以协整为基础的一系列计量经济学方法对两类价格之间进行了实证检验,结果显示我国的小麦期货市场不具有价格发现功能,而大豆期货市场具有此功能.为此进一步分析了两个市场表现不同的原因,并提出完善我国农产品市场运行机制的相关政策建议.     

中国农产品期货市场效率实证研究——以鸡蛋期货为例

鸡蛋期货是我国自1990年开通期货市场以来第一个鲜活农产品期货。自2013年11月8日在大连商品交易所上市至今,鸡蛋期货及现货的价格一直处于剧烈波动状态,故而鸡蛋期货市场的作用及效率一直饱受广大投资者的质疑。从目前对农产品期货市场的研究看,已有的研究对象绝大多数是小麦、玉米和大豆等市场上相对成熟的农产品期货品种,而对鸡蛋期货市场效率的研究比较缺乏。为了明确鸡蛋期货市场的市场效率情况,本文选取我国鸡蛋期货连续合约的结算价格、现货价格、成交量以及持仓量等指标,采用随机游走模型检验、协整检验、VAR模型以及格兰杰因果检验等方法对我国鸡蛋期货的市场效率进行实证分析,发现我国鸡蛋期货市场虽已初具价格发现功能,但仍需加强市场管理。     

我国工业品期货价格指数与PPI关系的实证研究——基于VAR模型和ECM模型

期货市场具有价格发现和套期保值的功能,期货价格指数作为期货市场运行的大盘指数,可以反映期货市场的整体运行状况以及市场主体对未来价格走势的心理预期,对于宏观经济具有重要的预警和预期引导作用。利用2004年6月至2016年12月南华工业品期货价格指数(NHG)收盘价和工业生产者出厂价格指数(PPI)数据进行实证分析,通过ADF单位根检验、建立VAR模型、Johansen协整检验,建立误差修正模型、Granger因果检验以及方差分解,检验南华工业品期货价格指数对PPI的先导作用及对宏观经济的预警作用。实证结果表明:NHG与PPI之间存在长期均衡关系,且NHG对PPI的走势影响显著,NHG对PPI存在先导作用,并至少领先PPI半年以上,目前来看,NHG对PPI的引导作用大概占到三分之一。因此,我国的南华工业品期货价格指数可以对PPI变动进行预警,且随着商品期货指数的不断完善,其必将对宏观经济指标发挥更为显著的预警作用。     

期货对房地产市场有效性的影响——基于美国CME房地产价格指数期货的研究

本文研究房地产市场上的金融创新,以美国房地产价格指数期货为研究对象,期货价格表示人们对未来价格的预期.由于期货市场存在便捷的双向交易,期货市场的价格发现功能理论上能够使得现货市场价格更加真实、走势更加平稳.同时,由于期货会影响价格进而可能会改变市场有效性水平.本文中采用GS模型验证了美国房地产价格指数期货市场存在价格发现功能.进一步的利用单根检验考察的房地产价格指数期货市场的建立对房地产市场的有效性影响.总的来说,肯定了房地产价格指数期货这一新的金融衍生工具的正向作用,为更合理地解决我国当前房地产市场问题提供了新的思路.     

DJ-AIG指数与CPI的引导关系及我国期货市场的开放程度

期货市场具有价格发现、套期保值、投资套利三大基本功能.从国外的研究和实践经验来看,商品期货市场的期货价格指数可以反映未来总体商品价格的走势,可以起到预测未来通货膨胀状况的作用.     

我国黄金期货价格发现功能的实证研究

价格发现是反映期货市场效率的一个重要功能。利用协整检验、Granger因果关系检验等方法对我国黄金期货市场与现货市场之间的动态关系进行实证研究的结果显示：我国黄金期货市场和现货市场之间不存在长期均衡关系,并且二者不能相互引导,我国黄金期货市场尚不具有价格发现功能。     

我国小麦期货市场功能发挥状况实证研究

本文从三个方面来考察期货市场功能的发展状况,一是先行性,二是预测性,三是期货市场套期保值比率及套期保值绩效.通过对三个方面的实证分析,得出小麦现货价格与小麦期货价格的波动方向具有一致性,且小麦期货价格对合约到期日的现货价格具有较强的预测能力,但期货市场的套期保值绩效却很差.     

农产品期货对现货保障的实证分析——以湖北省菜籽油产业为例

农产品期货市场对农业发展是否有正面积极效应,仁者见仁智者见智.为此,本文对菜籽油期货价格和湖北省菜籽油现货价格之间的关系进行了单位根检验和协整分析,发现二者之间波动趋势一致.然后又对二者进行了格兰杰检验和方差分析,进一步发现二者之间存在单向的因果关系,且菜籽油期货市场对湖北省菜籽油现货有套期保值和价格发现功能.本文研究说明菜籽油期货市场对湖北省菜籽油产业的发展具有保障作用.     

我国农产品期货市场价格发现功能研究——基于VECM模型的实证分析

价格发现功能是期货市场最重要的功能之一,期货市场的价格发现功能能够为市场参与者提供产品的均衡价格信息。文章在VECM模型的基础上运用修正后的长短期模型和信息份额模型对我国农产品期货市场与现货市场的价格发现功能进行研究,并通过脉冲响应函数研究两者之间的动态变化。结果表明我国农产品期货市场与现货市场的价格发现功能大致相当,期货市场价格发现功能没有占据绝对的主导地位。     

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.
