银行间市场投资人结构及监管:理论综述及国外实践

银行间市场在我国金融市场体系中的地位和作用日益突出,也成为促进我国金融结构优化不可或缺的重要因素,当对于其内涵和功能,学术界还存在一些不同的认识。银行间市场的投资人及监管,是该市场健康发展的核心要素,对此我们有必要在重新梳理其基本特点的同时,选择国外类似的市场进行比较分析,从而找出可资借鉴的经验。     

农村民间金融组织及其规范

农村民间金融组织的发展缓解了农村金融资金供需矛盾,弥补了官方金融的供给不足.但由于所掌握信息的有限性以及规模和范围上的劣势,使其在发展和运行过程中仍然存在一定的问题.因此,必须通过完善政策法规,加强监督管理和体制创新等措施进行规范.     

中国私营企业的生产率表现和投资效率

本文利用第一次全国经济普查数据系统地研究中国私营企业的生产率表现和投资效率问题。样本分析表明,东部地区材料和机械设备制造业的私营企业在劳动生产率和资本生产率上都明显领先于其他地区,然而这种优势主要集中表现在规模较大的企业上。生产函数的估计结果显示各地区大部分行业的资本弹性稳定地处于0.2—0.3之间。对生产率方差的分解表明,地区和行业内部近90%的生产率差异来自TFP的差异,劳均资本的差异只占贡献来源的13%左右。虽然行业间生产率差异的主要来源还是TFP,但地区间的生产率差异则主要来源于劳均资本的差异。资本边际产出在地区间和行业间的不均衡分布意味着部门间存在资本配置的非效率。我们通过模拟实验发现,省际间资本重置给私营制造业带来的潜在产出增长效果比行业间的资本重置更加明显,这意味着私营制造业资本的地区间流动障碍比行业间障碍更为严重。     

国有商业银行引进战略投资者的偏失及矫正思路

作为国有商业银行股份制改革的重要途径之一,自2005年6月起,我国国有商业银行积极引进战略投资者.截止到目前为止,四家国有独资商业银行除中国农业银行外均已完成了战略投费者的引进工作.但从战略引资的现实情况来看,由于受制于多种制度因素的制约,无论从引赘对象、引资目标还是引赘过程上看,笔者认为,我国目前国有商业银行引进战略投资者的行为都是有所偏失的.因此在对这一问题进行剖析的基础上,对固有商业银行的引责行为进行矫正具有重要的现实意义.     

全流通环境下投资者利益保护研究——控股股东、中小股东和经理人三方博弈分析

随着上市公司控制权的转移,投资者保护在全流通环境下有了新的内涵。文章从公司的委托代理问题出发,构建了控股股东、中小股东和经理人的三方博弈模型。各方决策的混合策略纳什均衡结果显示,股权的集中在一定程度上可以抑制公司的内部人控制;为保护投资者利益,应对控股股东和经理人的违规操作进行严厉惩罚,降低投资者的监督稽查成本,健全上市公司的治理机制。     

Private enforcement,corruption, and antitrust design

We examine how the rationale for enabling versus precluding private antitrust enforcement depends on whether antitrust enforcement is corruption-free or plagued by corruption. Corruption in courts affects the incentives to bring forth private antitrust lawsuits. This, in turn, along with corruption in antitrust agency enforcement, alters the incentives to commit antitrust violations. The social welfare effect of enabling private antitrust enforcement in the presence of corruption depends on whether corrupt officials in the ensuing bribery contests favor a particular firm and if so which one and to what extent. Under some circumstances, corruption actually increases the social desirability of private antitrust enforcement relative to the no-corruption scenario. Our analysis highlights that the effects of a given legal arrangement for antitrust enforcement critically depend on the corruption environment and, thus, that the appropriate design of antitrust institutions is context-specific.     

Mass media effects on trading activities: television broadcasting evidence from Japan

This study examines how information broadcasting through television (TV) media influences stock market activities. Consistent with the effect of TV information to attract investor attention, we find that increased information flow through TV is significantly associated with greater trading volume and larger price change. For information type, hard news from business-oriented programmes and earnings-related news strongly contributes to the attention effect, while the effect of soft news is weaker. Bid–ask spread widens for more TV information flows, suggesting that new information arrival in the market expands information asymmetry. Finally, the impact of TV is more influential for stocks with more individual shareholders than those with institutional shareholders.     

In search of stars: Network formation among heterogeneous agents

This paper reports results from a laboratory experiment on network formation among heterogeneous agents. The experimental design extends the Bala–Goyal [Bala, V., Goyal, S., 2000. A non-cooperative model of network formation, Econometrica 68, 1131–1230] model of network formation with decay and two-way flow of benefits by introducing agents with lower linking costs or higher benefits to others. Furthermore, agents' types may be common knowledge or private information. In all treatments, the (efficient) equilibrium network has a “star” structure. While equilibrium predictions fail completely with homogeneous agents, star networks frequently occur with heterogeneous agents. Stars are not born but rather develop: with a high-value agent, the network's centrality, stability, and efficiency all increase over time. A structural econometric model based on best response dynamics and other-regarding preferences is used to analyze individual linking behavior. Maximum-likelihood estimates of the underlying structural parameters, obtained by pooling data from several treatments, allow us to explain the main treatment effects.     

Productivity spillovers through backward linkages: The role of the origin of investors and absorptive capacity of domestic firms

We argue that multinationals from different home countries have different technologies and input sourcing behavior. These differences impinge on potential productivity spillovers through backward linkages of multinationals and such effects also differ across host local firms depending on their absorptive capacity. Using a panel of Cameroonian manufacturing firms over the period 1993 to 2005, we find supportive evidence of these arguments. There is a negative relationship between the presence of American and European affiliates in downstream sectors and the productivity of Cameroonian firms in the supplying industries and a positive correlation in the case of Asian affiliates. The absorptive capacity of Cameroonian firms mainly explains these divergent results.     

媒体报道、投资者情绪与IPO抑价——来自创业板的证据

以2009年10月创业板开板以来至2011年3月底的所有创业板IPO公司为研究样本,探讨了媒体报道在IPO抑价中的作用。通过测量招股公告日至上市日前一天的媒体报道数量,发现媒体报道与IPO抑价率正相关,并且媒体报道与IPO抑价的关系是以投资者情绪为桥梁的。此外还发现,创业板IPO存在显著的周历效应,周五上市的公司比例高...
