The Chinese Stock Dividend Puzzle

In this paper, we examine the announcement effects of dividends with an emphasis on stock dividends in China's capital market. We find that dividend-paying stocks exhibit significantly positive abnormal returns while non-dividend-paying stocks show a negative announcement effect. Further, we document that the cumulative abnormal returns for pure stock dividends and combined dividends are the main drivers of this announcement effect. In contrast, pure cash dividend stocks experience no significant price run-up before announcement. The significant announcement effect of stock dividends is robust to controlling the earnings surprise effect. We offer some discussion of the possible explanations.     

上市公司资产剥离效应实证分析

通过描述证券市场股价的变化和将公司的财务状况与2001年相比较,对2002年上市公司资产剥离的效应进行了分析。结论是中国证券市场的价格信息并不完全反映公司的实际发展状况,在资产剥离事件上偏离较大。作为公司实现经营目标所采取的一种手段,资产剥离发挥了重要的作用。     

公司策略性媒体披露行为研究最新进展与述评

因为新闻媒体对资产定价的重要影响,致使越来越多公司管理层开始重视对媒体披露的主动管理,特别是重大事件期间,公司的策略性媒体披露倾向尤为明显,以谋求自身利益的最大化。与此同时,这一现象也日益为学者们所关注,并开始成为公司财务与金融研究的热点前沿。本文主要基于行为金融学视角,从公司策略性媒体披露的内涵、动因、方式、主要内容及表现等维度,对现有相关文献进行了系统梳理,旨在进一步剖析公司管理层在媒体披露中的重要作用,帮助人们更好地理解和把握股票市场波动的成因及本质。最后,就其未来研究方向做了进一步的探讨。     

企业社会责任能降低股价同步性吗？——基于强制披露企业社会责任报告的准自然实验

中国2008 年沪深证券交易所强制披露社会责任报告政策为笔者研究其政策效应提供了准 自然实验,文章以2006-2011 年中国A 股上市公司为样本,分别从信息不对称和代理成本两条路 径研究强制披露社会责任报告对股价同步性的影响。运用PSM-DID 双重差分模型研究发现: 强制 披露社会责任报告与股价同步性呈现显著负相关关系,说明强制披露社会责任报告有助于降低股 价同步性,在通过安慰剂实验、变量替换和平行效应检验等稳健性检验后,以上结论仍成立。对 影响路径的分析发现,强制披露社会责任报告通过降低信息不对称和代理成本影响未来股价同步 性。     

财务重述、管理层权力与股价崩盘风险：来自中国证券市场的经验证据

股市震荡引发投资者和监管层对股价崩盘风险的关注。从财务重述背后所反映的财务信息质量低下和公司治理失效出发,探讨其对股价崩盘风险的影响,结合管理层权力这一影响组织行为和产出能力的代理人特征,探讨其对财务重述与股价崩盘风险之间关系的影响。研究结果表明：相比未发生财务重述的公司,发生了财务重述的公司的股价崩盘风险明显更高;进一步纳入代理人特征———管理层权力后,发现代理人的这一特征对上述关系有明显的促进作用。     

Does the bond‐stock earnings yield differential model predict equity market corrections better than high P/E models?

We extend the literature on crash prediction models in three main ways. First, we explicitly relate crash prediction measures and asset pricing models. Second, we present a statistical significance test for crash prediction models. Finally, we propose a definition and a measure of robustness for these models. We apply our statistical test and measure the robustness of selected model specifications of the Price‐Earnings (P/E) ratio and Bond Stock Earning Yield Differential (BSEYD) measures. This analysis shows that the BSEYD and P/E ratios, were statistically significant robust predictors of corrections on the US equity market over the period 1964 to 2014.     

Rollover risk and credit risk under time-varying margin

For a firm financed by a mixture of collateralized (short-term) debt and uncollateralized (long-term) debt, we show that fluctuations in margin requirements, reflecting funding liquidity shocks, lead to increasing the firm’s default risk and credit spreads. The severity with which a firm is hit by increasing margin requirements highly depends on both its financing structure and debt maturity structure. Our results imply that an additional premium should be added when evaluating debt in order to account for rollover risks, especially for short-matured bonds. In terms of policy implications, our results strongly indicate that regulators should intervene fast to curtail margins in crisis periods and maintain a reasonably low margin level in order to effectively prevent creditors’ run on debt.     

The impact of economic policy uncertainty on stock returns of Turkish tourism companies

Economic policy uncertainty (EPU) has various implications for financial markets. This study examines the effects of EPU on stock prices of listed tourism companies in Turkey for the time period of 2002–2013. We show that EPU in Europe and Turkey has significant negative effects on tourism index returns. The finding reflects that stock returns of the Turkish tourism companies apparently depend on domestic and international economic uncertainty. Among the included macroeconomic variables, consumer confidence index is the only factor which has an impact on stock returns.
