我国股市属于无效市场,存在投机过度的现象。究其原因,在于股市存在虚假信息披露现象。本文通过建立造假与监管的博弈模型,得到了上市公司与证券监管部门的三个纳什均衡,并进一步分析了监管的有效性,找到了根治信息造假行为的切实可行的办法。随后根据以上分析,提出了建立有效股市的若干个建议。  相似文献

随着证监会公布新股发行体制改革征求意见稿已满一个月,市场对于正式方案中加重处罚股市造假行为的呼声日益高涨。尽管在征求意见稿中加强了对新股发行过程中造假行为的监管,但市场普遍认为对造假的惩处力度仍很不足够。尤其是证监会对万福生科欺诈上市事件的处理结果被认为处罚过轻,平安证券因此事只被暂停三个月保荐资格,而保荐人只被罚款30万。轻罚造假无异于隔靴搔痒,违法成本过低只会纵容上市公司造假成风,因此必须加大证券犯罪的法律惩处力度。从绿大地造假事件到此次万福生科欺诈上市,从伪造财务报表到IPO“带病”上市,造假之风已经渗透到中国股市的各个方面。不断发生的造假事件,已经严重侵害了投资者利益,  相似文献

本文考察了股市收益波动与上市公司现金持有决策之间的关系发现:股市收益波动与公司现金持有变化呈负相关关系;上述负相关关系在国有企业以及监管行业企业中更为显著;上述负相关关系在牛市的时候更为显著。本文研究证实了上市公司存在利用自有资金进行证券投资的现象,明确政策监管的监管重点和监管周期,并提出了相关政策建议。  相似文献

关注金融市场间的风险传染性对于防范金融风险、提高监管效率有着重要的意义.运用多元GARCH模型研究汇改后(2005年7月22日到2009年8月31日)中国股票市场与外汇市场的信息传导过程,其结果表明汇市的波动风险会传染给股市,而股市的波动则不会对汇市产生明显影响,股市与汇市之间的溢出效应是非对称的.分阶段研究显示,在牛市阶段,股市对汇市存在微弱的信息溢出效应;熊市阶段,只存在单向溢出效应,随着时间的推移,汇市对股市的溢出效应逐渐增强.  相似文献

不断完善和发展资本市场一直是经济领域持久的课题,我国一直在为制度的完善而努力.但在资本市场日益发展的进程中,出于利益驱动等目的 的上市公司财务造假案仍时有发生,杜绝财务造假现象需要公司自身遵守法律规则的同时也对审计工作和行业监管提出了更高的要求.本文就A公司的七年造假之路进行论述,就其造假手段、审计过程中的问题和失败原因等方面进行分析,最后提出改进建议.  相似文献

本文以1994-2011年沪深两市财务造假上市公司为观察样本,首次全面综合地检验了国内外研究中表征财务造假和盈余质量问题的特征指标和西方资本市场常用的财务造假预测模型中的变量,建立了适合中国市场的更为可靠并且实用性强的财务造假预测模型。通过筛选检验大量的变量,本文发现其他应收款、是否亏损、经营应计项、现金销售率、股票换手率波动率、股权集中度、机构投资者持股比率、是否再融资和股市周期是鉴别中国上市公司造假的关键变量,用这些指标建立的综合模型不仅具有简单易懂的实用性,而且在辨别国内造假公司的能力方面显著优于西方常用的Mscore和Fscore模型。本文的研究结果为资本市场投资者、分析师、审计师和相关监管机构识别中国上市公司财务欺诈的嫌疑提供了简单实用的可靠方法。  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
