基于1257家主板上市公司2004—2014年的数据,运用分组固定效应模型,考量中国上市公司的股利政策。结果表明：相比其他估计技术,分组固定效应模型的研究结果更为准确。中国上市公司在股利分配政策上具有长远规划,股利政策存在异质性且缺乏稳定性,股利平均支付比率处于较低水平。     

The Role of Payout Ratio in the Relationship Between Stock Returns and Dividend Yield

Abstract:   This paper examines the relationship between returns and dividend yield in the UK stock market, and introduces earnings‐related data to the asset pricing model in the form of payout ratio. The latter has a considerable effect upon the inferences which would otherwise be drawn from a study of the dividend yield‐returns relationship in the absence of such earnings information. Payout ratio conveys additional signalling information and is an important adjunct to dividend yield in explaining returns.     

Dividend Policy, Corporate Governance and the Managerial Entrenchment Hypothesis: An Empirical Analysis

This paper analyses the agency explanation for the cross-sectional variation of corporate dividend policy in the UK by looking at the managerial entrenchment hypothesis drawn from the agency literature. Consistent with predictions, a significant U-shaped relationship between dividend payout ratios and insider ownership is observed for a large (exceeding 600 firms) sample of UK companies and two distinct periods. These results strongly suggest the possibility of managerial entrenchment when insider ownership reaches a threshold of around 30%. Evidence is also presented that non-beneficial holdings by insiders can lead to entrenchment in conjunction with shares held beneficially.     

资产定价理论实证研究及其发展

迄今为止,学术界关于风险—收益关系的实证研究始终未能取得一致、稳健的结论。本文对当前国内外学术界的相关实证研究进行了全面的梳理和分类,根据实证结论将已有文献大致分成了三类：风险与收益正相关、风险与收益负相关以及风险与收益不相关或关系较为复杂。本文重点探讨了国内学术界的研究现状,并认为从行为角度出发进行风险与收益权衡关系的理论与实证研究是极具潜力的研究方向。     

An Empirical Examination of the Dissemination of Equity Price Innovations Between the Emerging Markets of Nordic-Baltic States and Major Advanced Markets

: We employ three econometric models to examine the relative influence of the stock markets of the United States, the United Kingdom, France, and Germany on the stock markets of the Nordic-Baltic states. The results show that the Nordic-Baltic markets respond to price innovations from the United States, the United Kingdom, France, and Germany in diverse ways in the period 2001–2013. Response patterns for Finland, Norway, Sweden, Iceland, and Denmark are more significant to market innovations from the United States, the United Kingdom, and France, and less significant to those from Germany. German influence is more significant over Latvia, Lithuania, and Estonia than the rest of the advanced markets. While the dynamics of the Nordic-Baltic markets exhibit a dominance of own price innovation, the influence of the United States is stronger than that of France, the United Kingdom, and Germany. These results imply that investors from the Nordic States may derive greater benefits by diversifying into Germany and vice versa, rather than diversifying into the United States, the United Kingdom, or France. Investors from the Baltic States may obtain greater advantages by adopting portfolio strategies that take advantage of potentially better diversification benefits obtainable from the United States, the United Kingdom, and France rather than from Germany, and the reverse will also be in order.     

Dividend Payouts and Corporate Governance Quality: An Empirical Investigation

Motivated by agency theory, we investigate how a firm's overall quality of corporate governance affects its dividend policy. Using a large sample of firms with governance data from The Institutional Shareholder Services, we find that firms with stronger governance exhibit a higher propensity to pay dividends, and, similarly, dividend payers tend to pay larger dividends. The results are consistent with the notion that shareholders of firms with better governance quality are able to force managers to disgorge more cash through dividends, thereby reducing what is left for expropriation by opportunistic managers. We employ the two‐stage least squares approach to cope with possible endogeneity and still obtain consistent results. Our results are important as they show that corporate governance quality does have a palpable impact on critical corporate decisions such as dividend policy.     

人民币汇率波动与中国股票价格报酬之间的相关性——基于2005年至2007年的实证分析

本文以2005年7月21日至2007年9月18日的中国股价与人民币兑美元的名义汇率数据,利用GARCH模型来探讨在这段时间内人民币汇率波动对中国股票价格报酬的影响。实证结果得知,在这段时间内人民币兑美元名义汇率波动是负向影响中国股票价格报酬的,也符合有价证券余额理论的主张;汇率市场对股票市场的影响在宏观决策中应予以高度重视。     

中国货币供应量与股票市场价格关系的实证分析

股票市场作为货币政策传导的渠道,一方面通过货币供应量影响股票市场价格,另一方面股票市场价格的变动反馈到投资、消费等领域,从而影响宏观经济以实现货币政策的目标。本文对我国货币供应量与股票市场价格关系进行了实证检验,分析检验结果后认为我国各层次的货币供应量与股票市场价格存在长期的协整关系,其中股票市场价格处于因方地位,货币供应量处于果方地位。本文的实证结论在一定程度上反映了目前我国股票市场的货币政策传导效率不高,还没有发挥其应有的作用,这与我国股票市场自身缺陷有很大关系。     

The Influence of a Credit Rating Change on Dividend and Investment Policy Interactions

We examine firms’ alterations in dividend and investment activities following credit rating changes. We find that downgraded firms reduce both dividends and investments more than no‐rating‐change firms. However, a silver lining of this doubly negative impact for shareholders is an increase in investment efficiency in firms that are most likely to overinvest. For upgraded firms, investments increase, but dividend outlays do not, compared to firms without rating changes. Our findings of asymmetric dividend stickiness and symmetric investment changes on a credit shock suggest that dividends and investments should not always be considered competing uses of funds.     

基于VAR模型对CPI与房地产价格关系的实证分析

随着经济的不断发展,物价波动与房地产价格之间的关系逐渐成为关注的焦点。本文选取我国2006年1月至2010年12月的CPI和房屋销售价格指数月度数据,建立VAR模型。通过格兰杰因果检验发现:房地产价格和物价波动之间存在单向的因果关系。通过脉冲响应函数进行分析,表明房屋销售价格指数对CPI有着正向的作用。方差分解的结果说明在长期CPI的变动很大程度是由房屋销售价格指数引起的,房地产市场价格波动受自身因素的影响较大。     

An Examination of the Empirical Relationship between the Dividend and Investment Decisions: A Note

This paper empirically examines the separation principle, which asserts that investment decisions are not influenced by dividend decisions. Existing empirical evidence on this proposition is inconclusive. In this paper, we employ causality tests to examine whether investment decisions are, in fact, statistically exogenous with respect to dividend decisions. These tests are undertaken using both firm-specific and aggregate data. The results indicate no causal relationship from dividends to investment, which provides support for the separation principle as an empirical proposition.     

An Empirical Study of Volatility in Seven Southeast Asian Stock Markets Using ARV Models

This paper investigates the volatility persistence, volatility variability from day to day and transmission of volatility in seven Southeast Asian stock markets from 1980 to 1991 using the ARV approach. We found strong evidence that shocks to volatility are persistent in Taiwan. Moreover, the Stock Exchange of Thailand Daily Index has the strongest interday volatility fluctuation. Instantaneous causality of volatility among six of the seven markets (except Seoul) was discovered. Besides, there is significant volatility spillover effect from Hong Kong to Taiwan, Malaysia to Singapore and Singapore to Malaysia in the period 1980 to 1991.     

Empirical Analysis of Stock Returns and Volatility: Evidence from Seven Asian Stock Markets Based on TAR-GARCH Model

This paper investigates the time-series behavior of stock returns for seven Asian stock markets. In most cases, higher average returns appear to be associated with a higher level of volatility. Testing the relationship between stock returns and unexpected volatility, the evidence shows that four out of seven Asian stock markets have significant results. Further analyzing the relationship between stock returns and time-varying volatility by using Threshold Autoregressive GARCH(1,1)-in-mean specification indicates that the null hypothesis of no asymmetric effect on the conditional volatility is rejected for the daily data. However, the null cannot be rejected for the monthly data.     

机构投资者持股与股价同步性分析

本文利用中国证券市场所有A股上市公司2005～2007年的面板数据,对股价同步性和代表机构投资者持股的三个变量——机构投资者持股比例、机构投资者持股变化和持股机构投资者数量进行回归统计,检验了机构投资者持股对股价同步性的影响。研究表明,代表机构投资者持股的三个变量都与股票股价同步性显著负相关,其中机构投资者持股变化是影响股价同步性的决定性因素,其他两个变量都是通过该变量发生作用的。这一结果说明机构投资者利用公司特质信息进行的基于信息的交易提高了股价中的信息含量,降低了股价同步性。     

Dividend Irrelevance and Accounting Models of Value

In accounting models of value, dividends typically appear to have a strong positive relationship with value despite theoretical reasons to expect dividend displacement. We show that this result is driven by the relationship between dividends and both core earnings and other information derived from the valuation error in the prior year. Where core earnings can be effectively modelled in a specification including other information, dividend displacement is no longer rejected. Under these circumstances dividends exhibit weak incremental predictive power for earnings and earnings expectations and hence have little impact on value. We show that valuation models are sensitive to model specification and should be used with caution when testing the value impact of firm characteristics or accounting numbers.     

Option Implied Dividends Predict Dividend Cuts: Evidence from the Financial Crisis

We employ the forward‐looking implied dividend information contained in option prices to predict dividend cuts and omissions during the recent financial crisis. The large number of dividend cuts and omissions during the 2008–09 financial crisis period provides the opportunity to study the predictability of dividend cuts in a controlled environment. Implied dividends and implied volatility, based on put–call parity and computed from put and call option prices, prove to be effective in predicting those cuts, especially compared to only using the equity market and accounting variables conventionally used for this purpose. Options‐derived variables (implied dividends and implied volatility) enhance the ability to identify firms more likely to reduce or omit dividend payments.     

人民币升值、股价上涨和热钱流入关系的实证研究

本文基于CLR(1996)模型和多重套利模型(2007)这两个重要理论模型来解释国内人民币升值、股票价格上涨和热钱流入之间存在的互动关系。并结合样本数据通过Granger因果关系对人民币升值、股票价格上涨和热钱流入的关系进行了实证检验。结果显示:人民币升值和上证综合指数上涨是热钱流入中国大陆的原因,但热钱流入不是人民币升值和上证综合指数上涨的原因。对理论模型解释和实证检验结果之间出现的异同。本文做出分析和解释。最后给出政策建议。     

融资融券试点对我国股票市场波动性的影响实证研究

融资融券交易正式启动对我国股票市场将产生什么样的波动性影响,是学术界和理论界共同关注的焦点。本文在前人研究基础上,从我国实际情况出发,以标的证券指数——上证50指数与深证成指指数作为影响我国股票市场的代表展开实证,运用GARCH族模型,引入虚拟变量D,其中D用来刻画融资融券推出前后对我国股票市场的影响。通过建模,得出融资融券试点一年多时间以来有利于减小我国股票市场波动性的结论。     

“两税合一”对台湾上市公司股利税资本化的影响

本文以1994～2001年两税合一税制实施前后的台湾上市公司为样本，运用Harris-Kemsley股利税后收益模型，探讨所得税制改革对权益投资者收益的影响，以及两税合一税制的实施对股利税资本化的影响。实证结果表明：两税合一税制实施前，台湾上市公司的末分配盈余与其股利税资本化程度负相关，即股利税资本化效果存在；两税合一税制实施后，台湾上市公司的股利税资本化程度低于两税合一前的程度。
