对于以组合管理为基本方法的证券投资基金,由于其投资风格选择的不同会导致投资者对其投资偏好的差异,加之证券市场的非有效性和投资者的非完全理性,投资者对基金的投资决策更多基于心理动机和行为因素的判断。本文运用行为组合理论,对我国证券市场封闭式基金的折价状况进行了考察,分析了证券投资基金投资风格选择对基金需求的影响及我国证券市场投资者的需求特点和偏好状况。  相似文献

传统的金融理论认为,投资者是理性的,是按照效用最大化来进行的决策,然而从证券市场的实际情况来看,投资者的决策行为并不是完全理性而是有限理性的。在中国证券市场上,由于市场发展快速,制度不够完善,投资者的有限理性决策行为表现更为突出,这导致了证券市场的波动,增加了市场的风险。因此,有必要对投资者的有限理性决策行为进行深入研究,从而了解投资者的决策偏差及原因,引导投资者理性投资,促进中国证券市场的健康发展。  相似文献

中国机构投资者投资行为的异化   总被引:2,自引:0,他引:2  
李俊英 《新金融》2008,(7):57-59
在我国机构投资者迅猛发展的同时,其投资行为也在发生异化,与政府和市场的最初预期产生明显的偏羞。机构投资者投资行为的异化典型地表现为:短视行为、羊群行为、处置效应和违法违规行为。机构投资者投资行为的异化严重扰乱了证券市场的正常秩序,加剧了市场风险的累积。中国证券市场的非理性波动其实并非由非理性的个人投资者所引起,而正是由行为相对更为“理性”的机构投资者(他们构成了庄家的大部分)所引起。  相似文献

在金融学中比较注重对证券投资者在投资时的心理特征进行研究。是因为其决策可以引起许多证券市场的异常现象,也正是因为这些决策行为引起了证券市场的变化。本文将从金融学视角对我国证券投资者的行为进行研究,并进行分析,为提高证券投资者的理性投资奠定良好的基础。  相似文献

在我国基金业迅猛发展的同时,基金经理的投资行为也在发生异化,典型的表现为:短视行为、羊群行为和坐庄行为。他们作为相对“理性”的机构投资者严重扰乱了证券市场的正常秩序。本文从委托代理问题的角度出发,在已有的行为金融学文献研究的基础上,挖掘基金经理投资行为异化的内因和外因,同时寻找一些方法来减轻这些因素对中国证券市场稳定与发展的影响。  相似文献

造成我国证券市场羊群行为的原因包括宏观和微观两个层面。本文从宏观和微观两个层面提出抑制羊群行为的相应策略,即培育市场理性与培育理性投资主体两项对策。前者具体包括:完善信息披露制度,使信息发布有利于投资者形成稳定的预期;提高上市公司质量,以改善供求关系;交易成本适度化,提高证券市场的效率;后者具体包括:培育理性投资者和机构投资者,完善基金评价机制,实现证券市场的充分竞争。  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献

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.  相似文献
