股票市场的价格波动并非像传统金融学所说得那样围绕公司基本价值进行小幅震荡,常常表现出大幅波动的特征。本文采用基于garch模型作出的Shiller-Sentana-Wadhwani模型对中国股票市场成立十多年的股价波动进行实证研究,得出中国股票市场存在反馈交易且其程度随着股价波动的增大而提高、随着涨跌限制而加大的结论。 相似文献

从市场效应的角度来揭示重大资产重组事件对公司价值的影响。通过对2000-2003年中国上市公司的187个资产重组事件的平均股价和累计非正常收益率实证分析表明,市场对上市公司的重大资产重组有强烈的超前反应,资产重组给公司带来了一定的价值提升。 相似文献

本文以2001~2004年A股上市公司为研究对象,在国内首次验证了会计师事务所向审计客户同时提供审计与非审计服务,是否会允许管理当局有较大的盈余操纵空间,以探讨非审计服务的提供是否会影响注册会计师独立审计的质量。实证研究结果显示:在我国,控制了其他影响因素后,非审计服务的提供与异常应计数正相关,但不具有统计显著性。这表明,在我国,没有证据显示,非审计服务会的提供会损害注册会计师审计独立性及审计质量。 相似文献

上市公司控制权转移与市场反应 总被引:4,自引:0,他引:4
国外有研究表明,控制权转移能给目标公司股东带来20%左右的超额收益率.本文通过考察我国1997-2003发生控制权转移的282个样本,发现控制权转移能给目标公司带来9%以上的累积超额收益率.而且,转移后变更行业、变更董事长或总经理、民营转给国有的样本转移时可获得的累积超额收益率甚至更高.最后,我们用多元回归模型进一步分析了累积超额收益率的影响因素,进一步证明行业变更、董事长或总经理变更、转移类型对控制权转移的市场反应有显著影响. 相似文献

We extend prior research on the empirical properties of daily trading volume and methods to detect abnormal trading volume in two ways. We compare the performance of a nonparametric test statistic with the parametric test statistic used in prior research and we study samples of NASDAQ securities as well as samples of NYSE/ASE securities. Prior research has focused exclusively on NYSE securities. We find the nonparametric test statistic is more powerful in detecting abnormal trading volume than the parametric test statistic in both samples of NYSE/ASE and NASDAQ securities. We also document that abnormal trading volume will be detected more often in samples of NYSE/ASE securities compared to NASDAQ securities. 相似文献

On the distributional effects of exchange rate fluctuations 总被引:1,自引:0,他引:1

How do exchange rate movements affect different sectors of an economy? We address this question in a simple general equilibrium model, stressing the different exposures of various sectors to foreign competition, an aspect ignored in earlier contributions. The impact of exchange rate shifts is highly heterogenous across sectors. While a depreciation leads to a substantial competitiveness and welfare gain for agents with a high exposure to foreign competition, agents facing mostly domestic competition are adversely affected. 相似文献

This paper explores the wealth effects associated with a bidder's decision to solicit a fairness opinion in a takeover transaction. Using a hand‐collected sample with bidders’ filing proxy statements, this paper finds that the use of fairness opinions does not negatively affect bidder shareholders’ wealth, a finding that contradicts prior studies’ findings. In addition, I find a positive wealth effect associated with bidder use of fairness opinions in the post‐Rule 2290 period. Collectively, these results are consistent with a fairness opinion being used by bidder management as a means to facilitate transactions rather than a mechanism to entrench management. 相似文献

This article examines the effect of Warren Buffett’s investment in Goldman Sachs on 24 September 2008, during the subprime mortgage crisis. Although this event is arguably perceived to be the biggest expression of confidence in the financial market during the crisis, by conducting event studies, we do not find the major counterparties of Goldman Sachs displayed positive abnormal returns. Moreover, the abnormal return is not significantly related to the counterparty connection. We have similar findings on these financial institutions’ default probabilities using credit default swap. 相似文献

We examine fluctuations in employment growth using Canadian data from 1976 to 2010. We consider a wide range of models and examine the sensitivity of our findings to modelling assumptions. The results from our most preferred model, which we selected using the Bayesian Information Criteria, indicate that most of the variance in employment growth that is not due to the idiosyncratic error comes from domestic sources, with most of this coming from industry and provincial factors. Overall, we find that external and national factors play a much smaller role in employment fluctuations than in earlier research. We provide some possible explanations for these differences and discuss the implications of our findings for public policy and theory. 相似文献

This paper explores a wide range of corporate restructurings, all available deals from wire services, in the banking and insurance sectors that led to bancassurance ventures. An event study methodology is employed to calculate excess returns on and around the deals’ announcement date. Using both univariate and multivariate analysis the paper finds bank driven mergers, deal's size and regional categorization all triggering positive and significant market reactions. Unlike the univariate framework, multivariate analysis shows that geographic focus and language are not significant factors. The results also indicate that markets are indifferent with respect to bank withdrawals from the bank‐insurance operations. Finally, Canadian, U.S. and European bank‐insurance deals produce positive results, while Australasian bidders offer statistically insignificant equity returns. 相似文献
