内部控制、治理环境与投资者保护

本文研究了内部控制质量对投资者保护的影响,以及不同治理环境对内部控制治理功能的影响。研究发现:内部控制质量的提高,或更为充分的内控信息披露有助于抑制大股东资金占用,有助于抑制经理人与股东之间的代理成本;治理环境越差的地区,内部控制治理效应越高。这说明,对于投资者保护较弱的地区,内部控制可能成为补偿弱投资者保护负面影响的一种替代机制。本文研究意味着,近年来推出的内部控制相关制度起到了积极的效果;此外,完善上市公司内部控制,对于治理环境较差、投资者利益得不到有效保障的地区显得尤为重要。

The impact of investor structure on stock price crash sensitivity: Evidence from China's stock market

Stock price crash sensitivity refers to the conditional probability of a stock crash when the market collapses. It focuses on individual stocks' sensitivity to the market crash and can affect stock pricing significantly. Although the crash sensitivity of China's stock market is very high as a whole (Weigert, 2016), different individual stocks show varying degrees of crash sensitivity. This paper, adopting the perspective of institutional investors, explores the reasons for the difference in crash sensitivity in China's stock market, and finds that: First, institutional investors' shareholdings is positively related to firms' stock price crash sensitivity. However, after dividing institutional investors into professional (represented by financial institutions) and non-professional institutional investors (represented by general legal persons), we find that only professional institutional investors' shareholdings is negatively related to firms' stock price crash sensitivity. Second, the impact of professional institutional investors on the crash sensitivity is influenced by stock liquidity and media sentiment: when the stock liquidity of listed companies is good or the media sentiment is strong, the negative impact of professional institutional investors on the crash sensitivity is accordingly high. This paper, by highlighting the investor structure, attempts a pioneering exploration of the influencing factors of the difference in stock price crash sensitivity in China. Our empirical results enrich research on stock price crash sensitivity and the heterogeneity of institutional investors. They can also serve to guide regulatory authorities' development of institutional investors and efforts to maintain market stability.     

衍生金融工具的演变对公司法股东至上原则的影响及修正

传统公司法以股东至上为基本原则,并以此为轴心进行系列制度安排.衍生金融工具的应用,使股票与债券等原生金融工具蕴涵的收益与风险要素得以重新打包组合,满足投资者个性化需求.但是附着原生金融工具上的法律的权利与义务却未能完全对应地转移,使得股权与债权的界线逐渐模糊,形成公司法对除股东以外的其他类型投资者保护的缺口.公司法应该对这些新型的交易关系进行确认,对股东至上原则进行修正,调整保护对象和范围,容纳更多的与公司发展攸关的利益主体的利益诉求.     

Direct and representative participation in Europe: recent survey evidence

Despite the wealth of literature on HRM and employee involvement, now there has been a remarkable lack of large-scale survey evidence on the diffusion employee involvement in work organizations in Europe. This gap in large-scale survey evidence on the diffusion of direct employee participation has now been filled representative sample of workplaces in ten major European Union countries which commissioned by the European Foundation for the Improvement of Living and Working Conditions in Dublin (the EPOC project). It is by far the most comprehensive overview of the implementation and effects of direct employee participation of its kind. The paper shows that, on the basis of the EPOC survey results, there appears to considerable gap between the rhetoric and reality of direct participation. The paper shows that while the incidence of different forms of direct participation was widespread ten countries, the scope, in terms of number of issues involved and the number of given to employees, was relatively limited for most direct participation forms. The survey also showed that the introduction of direct participation posed little threat to trade representatives. Indeed, works councils and union representatives were in most 'agents of change' rather than barriers to the development of the more intensive practice of direct participation.     

公众注意力影响买入行为吗？——基于投资者行为的分析

公众注意力衡量了一只股票受投资者关注的广泛程度。本文分析了公众注意力对不同类型投资者买入行为的影响,发现小投资者更倾向于买入引起他们注意的股票,中大类型投资者没有明显与注意力相关的买入行为,机构投资者则表现出了与公众注意力相关的策略性行为。小投资者的这种特性使得他们更容易成为市场操纵的受害者,对此本文提出了相应的政策建议。     

S&P 500 Affiliation and Stock Price Informativeness

Abstract

When firms are added to a stock index, more information should be discovered, traded on, and incorporated into their stock prices, making them more informative. We test this hypothesis using a large sample of additions to the S&P 500 index. Using two alternative statistical tests, we find that the stocks added experience more random, less predictable return and, thus, appear to be priced more efficiently information-wise. We further find concurrent increases in institutional ownership and investor awareness, which tend to contribute to the higher pricing efficiency, adding to the literature. These findings should be of interest to academics and practitioners.     

Beauty contest,bounded rationality,and sentiment pricing dynamics

We present a dynamic asset pricing model that incorporates investor sentiment, bounded rationality and higher-order expectations to study how these factors affect asset pricing equilibrium. In the model, we utilize a two-period trading market and investors make decisions based on the heterogeneous expectations principle and the “sparsity-based bounded rational” sentiment. We find that bounded rationality results in mispricing and reduces it in next period. Investor sentiment produces more significant effects than private signals, optimistic investor sentiment increases hedging demand, thus causing prices to soar. Higher-order investors are more rational and attentive to the strategies of other participants rather than private signals. This model also derives the dampening effect of higher-order expectations to price volatility and the heterogeneity expectation depicts inconsistent investor behavior in financial markets. In the model, investors' expectations about future price is distorted by their sentiment and bounded rationality, so they obtain a biased mean from the signal extraction.     

异质机构、企业性质与自主创新

本文通过放松经理人市场的完全竞争性假定,拓展了经典职业生涯模型,藉此研究了中国制度背景下的机构持股、企业性质与企业创新的关系,并基于2004—2009年923家上市公司的数据,从R&D投入和专利申请两个维度对本文拓展模型的命题进行了实证检验。结果表明:(1)异质机构对企业创新有不同的影响,证券投资基金对企业创新有显著的负效应,这种负效应在国有企业中表现得更为明显;(2)民营企业中机构投资者持股促进了企业的创新活动,国有企业中机构投资者持股与企业创新呈显著的负相关关系;(3)机构投资者整体持股对全样本企业的专利申请有不显著的正效应,而对R&D投入则有显著的负效应。
