国外即兴研究的文献计量学分析

对国外即兴研究的进展状况进行了总结。以6个外文数据库——EBSCO、SAGE Premier、JohnWiley、Elsevier Science、Emerald和Taylor为文献检索源,对1991—2012年国外即兴研究文献进行检索。利用文献计量学方法对文献数量、发表期刊、主要作者和关键词进行统计分析,并利用文本挖掘方法、可视化软件Refviz以及信息熵方法对研究主题及其演化规律进行了分析。     

碳排放权交易市场的信息流动关系——基于EUA市场和CER市场的实证研究

基于Granger因果关系检验方法和MGARCH-BEKK模型,从报酬溢出和波动溢出的角度,研究国际碳排放权交易市场中的主要商品———EUAs和sCERs各自的期货价格与现货价格之间以及两者的期货价格之间的信息流动关系。结果表明:两个市场的现货市场始终都处于价格信息中心,期货市场的价格发现功能较弱甚至未体现;信息波动溢出方面,EUA市场中期货市场处于波动信息中心,而CER市场中现货市场处于波动信息中心;EUA的期货市场与CER的期货市场之间存在相互的价格溢出效应与波动溢出效应,但EUA市场的期货价格对CER市场具有更大的波动溢出效应。     

管理者过度自信对股权融资成本的影响——基于信息透明度的视角

以2009年和2010年具备股权再融资资格的中国上市公司为研究对象,从信息透明度的角度考察管理者过度自信对股权融资成本的影响。研究发现:管理者过度自信对上市公司的信息透明度和股权融资成本具有负面影响;具体而言,管理者越倾向于过度自信,上市公司的收益平滑度越高,因此收益透明度越低;相比非过度自信管理者所在的企业,过度自信管理者所在企业的股权融资成本更高。     

Strategic knowledge sharing in Bayesian games

This paper provides a model for the study of direct, public and strategic knowledge sharing in Bayesian games. We propose an equilibrium concept which takes into account communication possibilities of exogenously certifiable statements and in which beliefs off the equilibrium path are explicitly deduced from consistent possibility correspondences, without making reference to perturbed games. Properties of such an equilibrium and of revised knowledge are examined. In particular, it is shown that our equilibrium is always a sequential equilibrium of the associated extensive form game with communication. Finally, sufficient conditions for the existence of perfectly revealing or non-revealing equilibria are characterized in some classes of games. Several examples and economic applications are investigated.     

Trade mechanism selection in markets with frictions

We endogenize the trade mechanism in a search economy with many homogeneous sellers and many heterogeneous buyers of unobservable type. We study how heterogeneity and the traders' continuation values—which are endogenous—influence the sellers' choice of trade mechanism. Sellers trade off the probability of an immediate sale against the surplus expected from it, choosing whether to trade with everyone and how quickly. In equilibrium sellers may simply target one buyer type via non-negotiable offers (price posting), or may price discriminate (haggling). We also study when haggling generates trading delays. A price setting externality arises because of a strategic complementarity in the sellers' pricing choices.     

The Quantitative Law of Network Information Growth

Based on the assumptions of ＂information transfer＂ and ＂information creation＂, this paper educes the multiplied growth mechanism of network information： that the gross quantity of network information （Im） is about n times as much as the quantity of real network information （Ir）. According to this theoretical model, we give a uniform explanation to all kinds of information growth models in existence, and put forward some proposals, such as ＂forbidding information transfer＂ and ＂building up the central information base＂, to control the repeated information flooding on the network and facilitate the full use of network information.

利率管制松绑、企业会计信息披露质量与融资约束

已有研究发现,以资本价格——利率为代表的要素市场改革会对企业行为产生重要影响,但这种影响的作用机理如何通过改变资本市场中的信息供求关系予以实现,亟待深入研究。为此,本文以我国2013年央行全面放开利率管制为背景,基于产权性质差异构建双重差分模型,检验利率管制松绑在企业层面的信息溢出效应。研究发现:央行全面放开利率管制不仅有助于促进企业披露高质量的会计信息,还能够缓解企业的融资约束,且企业信息披露质量的提升是导致利率管制松绑降低融资约束的重要渠道。进一步研究发现,对于市场化程度较低地区、R&D投入较高以及短期贷款占比较大的公司,上述信息溢出效应更加显著;另外,利率管制松绑后企业披露高质量的会计信息能够增进投资者的信任,提高信息披露的价值相关性。以上研究结论表明,为应对利率市场化改革带来的机遇与挑战,保障可持续发展,企业会选择主动优化信息环境,来消除信贷市场摩擦,解决"融资难"问题。
