现金股利政策和股权结构来自行业效应的证据

本文检查了现金股利(现金股利发放率)和股权结构(第一大股东持股)之间的实证关系,考察了企业行业属性和成长性机会对股利政策股权效应的影响程度.作者发现,第一大股东具有发放现金股利的显著激励,行业属性只会对这种分配激励施加微弱影响.     

低现金股利政策、股东财富与控股股东决策

根据Jensen的自有现金流量假说,在不考虑股票回购条件下,将公司支付的现金股利数量低于自由现金流量定义为低现金股利政策.研究显示,低现金股利政策不利于股东财富最大化,在低现金股利政策范围内,提高现金股利会提高股东财富.但从控股股东财富最大化出发,实施低现金股利政策有助于实现其获取控制权私有收益以本身的财富最大化.     

现金股利与控股股东的利益输送行为研究——来自中国上市公司的经验证据

在存在控股股东的情况下,大股东的利益输送通常会造成对中小股东利益的侵犯,进而对资本市场的有效性造成影响。本文认为现金股利发放在中国上市公司中是作为控股股东利益输送的一种重要手段,对此的实证结果表明大股东的持股比例与公司发放现金股利的多少呈明显正相关关系;第二大股东和第三大股东不能对大股东利用现金股利转移现金进行监督;机构投资者的作用尚不明显。     

中国股市财富效应的实证检验

以股市规模快速发展、居民消费水平快速提高为背景,从消费函数的理论分析出发,运用协整理论和动态滞后分布模型对我国股票市场的财富效应问题展开研究。从股票市场规模与稳定性、企业和投资者参与程度、股票市场对资金的吸附等方面对我国股市财富效应问题进行考察。分析结果表明,我国股票市场规模的扩大不但没有促进消费支出的增长反而对消费产生挤出效应,即财富效应为负。     

控股股东所有权、投资者法律保护与侵占效应——来自中国上市公司的经验证据

中国上市公司普遍存在着控股股东,随着关于股东之间利益冲突的研究成为公司治理领域的热点,大量的目光集中于控股股东和利益侵占之间的关系上。国内外对于控股股东所有权集中程度和利益侵占之间关系的研究存在较大的争议,并且相对缺乏理论的解释。本研究针对中国上市公司治理的实际,首先对控股股东所有权集中和利益侵占进行理论分析,在此基础上提出理论假设,并利用中国A股上市公司面板数据进行实证检验,通过分析我们发现,控股股东所有权与关联交易为主要方式的侵占之间呈现非线性关系,而投资者法律保护有助于减少侵占规模,就此本文进一步提出了相应的政策建议。     

中国股市政策效应研究

一、中国股市政策效应研究述评中国股票市场素有政策市之称。人们普遍接受的政策市概念有两层含义:一是国家的宏观政策在很大程度上左右了股市的运行,这是一种不带价值评判的中性认识;二是国家的宏观政策过多地干预了股市的运行,导致股市频繁波动,这种认识带有批判色彩。政策效应是指政府、     

股改后的中国股市财富效应研究

启动于2004年的股权分置改革,旨在防范和化解市场风险、提高资本市场监管水平、提高上市公司质量.研究表明,股改后,我国股市财富效应在消费支出和杂项商品及服务支出方面明显增强.其结论是通过拉升股市刺激消费,提振经济的目的可以部分实现.

Instability in the dividend policy of the Istanbul Stock Exchange (ISE) corporations: evidence from an emerging market

Dividend policy behaviour of corporations operating in emerging markets is significantly different from the widely accepted dividend policy behaviour of corporations operating in developed markets. This study provides evidence from the Istanbul Stock Exchange (ISE), an emerging European stock market, and analyses empirically whether the ISE corporations follow stable cash dividend policies in a regulatory environment that imposed mandatory dividend policies. Unlike the empirical results supporting the stable dividend policy behaviour of corporations operating in developed markets, the empirical results show that the ISE corporations follow unstable cash dividend policies and the main factor that determines the amount of cash dividends is the earnings of the corporation in that year.     

CEO turnover and shareholder wealth: Evidence from CEO power in Taiwan

This paper investigates the relationship between CEO turnovers and shareholder wealth and/or the volatility of firm performance, and examines whether CEO power matters in this relationship. Successors tend to possess less power than predecessors. The announcement effects of CEO turnovers present higher abnormal returns for turnovers in which predecessors and successors share a similar power level and a lower volatility for turnovers in which successors have less power. Volatility is lower and liquidity is higher when CEO turnovers involve successors with less power.     

调控上网电价对稳定市场价格的政策效果实证研究

基于VAR模型和中介效应模型等定量分析手段,研究了我国上网电价波动对市场价格波动的影响效应,探索调控上网电价对稳定市场价格是否具有积极的政策效果。结果表明,上网电价的调整在滞后一期会对CPI和PPI产生负向冲击,从而抑制市场价格上涨,而随着滞后期不断增加,影响作用趋于减弱;同时,在上网电价波动影响市场价格波动的过程中,存在CPI和PPI之间相互中介效应,即存在上网电价→PPI→CPI、上网电价→CPI→PPI的影响途径。总体来看,我国调控上网电价,在一定程度上起到了稳定国内市场价格的积极作用。     

股改对中国证券市场有效性影响的实证分析

文章以2005年4月至2007年3月,沪深300指数所包含的股票为样本股,采用股价非同步指标对中国证券市场股价信息含量进行实证研究.结果表明,股权分置改革以后的证券市场中所包含的公司信息含量呈上升趋势,股权分置改革对市场效率的提高产生了积极影响.     

The effect of concentration and market power on food prices: evidence from Finland

This research examines empirically the relationship between economies of scale, concentration, and market power in food retailing. With unique, local market data available Finland, the analysis could investigate the impact of both local concentration and industry-wide concentration (which can be interpreted as multimarket contact) are taken into account in the evaluation of grocery retail competitiveness. The results show that the main factor affecting market power is the size of the retail firm. Larger share grocery retailers, for both the local and the national markets, carried higher mark-ups. At the same time, no firm-level scale economies were found from these larger firms. I conclude from these findings that the main purpose of large grocery retail mergers is to gain market power not efficiency.     

民营上市公司现金股利信号传递效应实证研究

系统考察股利分配预案公告日我国民营上市公司现金股利信息的信号传递效应,并在研究方法上对我国当前该领域研究中所存在的缺陷进行了弥补。在严格控制了盈余信息、公司规模等因素后,分别对2001-2003年度我国民营上市公司股利分配预案公告日前后样本(除送、配方案之外)的“纯”现金股利分配预案的市场反应进行了分析。结果发现,股利分配预案公告日前后,民营上市公司发放现金股利并没有受到市场排斥,其超常收益显著为正。     

Monetary and fiscal policy transmission in the Euro-area: evidence from a structural VAR analysis

This paper studies the transmission of monetary and fiscal policy in the Euro-area. To do so, structural VAR models are estimated. First, the EMU countries are considered as an aggregate entity and the estimation results are compared with those for the US and Japan. Attention is also paid to interaction of macroeconomic policies and the effects of shocks in financial markets. As a next step, SVARs are estimated for the individual EMU countries to analyze cross-country differences. It turns out that, compared to the EMU aggregate, individual EU countries react rather differently to monetary and fiscal policy shocks.     

我国上市公司并购财富效应的行业特征研究与实证分析

并购的财富效应存在明显的行业差异,主要体现在行业的发展阶段、发展战略和发展能力这三类行业特征上。通过产业经济学中结构—行为—绩效范式建立理论框架,利用中国1998—2008年沪深两市6962起并购事件进行实证。研究结果表明:行业的财富效应与发展阶段正相关,与发展能力也正相关,并且行业发展阶段和发展能力对股东并购超额收益率的贡献分别为7‰和0.2‰;但是行业集中度并不是显著影响并购财富效应的行业特征。     

Ethics and the Ivory Tower: The Case of Academic Departments of Finance

This study reports the results from a survey of 1,000 finance faculty members within schools of business across the U.S. concerning their knowledge of ethical transgressions as well as their attitudes towards ethics training in the curriculum. Ethical breaches appear most frequently with the unauthorized duplication of licensed software and the misuse of university resources for private consulting activity. Yet knowledge of ethical misconduct is highly segmented, with significant differences in reporting frequency between groups based upon citizenship, academic rank and school size. Contrary to the implications of Hawley (1991), we find there is a widely held belief by finance educators that business ethics has a legitimate role in business curriculums and should be included in finance course work. Further, our respondents strongly reject the notions that ethical practices are inconsistent with the principle of shareholder wealth maximization or that finance is more susceptible to ethical transgressions than other functional areas of business. We conclude that finance faculty are able to serve as legitimate ethical mentors for students and by implication may positively influence future corporate ethical behavior.     

The Nature of the Firm, Agency Theory and Shareholder Theory: A Critique from Philosophical Anthropology

Standard accounts on the nature of the firm are highly dependent on explanations by Coase, coupled with inputs from agency theory and shareholder theory. This paper carries out their critique in light of personalist and common good postulates. It shows how personalist and common good principles create a framework that not only accommodates business ethics better but also affords a more compelling understanding of business as a whole.Joan Fontrodona is Assistant Professor of Business Ethics and Academic Director of the Center for Business in Society at IESE Business School.
