Banks’ equity performance and the term structure of interest rates

Using an extensive global sample, this paper investigates the impact of the term structure of interest rates on bank equity returns. Decomposing the yield curve to its three constituents (level, slope and curvature), the paper evaluates the time‐varying sensitivity of the bank's equity returns to these constituents by using a diagonal dynamic conditional correlation multivariate GARCH framework. Evidence reveals that the empirical proxies for the three factors explain the variations in equity returns above and beyond the market‐wide effect. More specifically, shocks to the long‐term (level) and short‐term (slope) factors have a statistically significant impact on equity returns, while those on the medium‐term (curvature) factor are less clear‐cut. Bank size plays an important role in the sense that exposures are higher for SIFIs and large banks compared to medium and small banks. Moreover, banks exhibit greater sensitivities to all risk factors during the crisis and post‐crisis periods compared to the pre‐crisis period; though these sensitivities do not differ for market‐oriented and bank‐oriented financial systems.     

个人投资者交易行为研究——来自台湾股市的证据

本文基于台湾股市数据,主要研究个人投资者的交易行为。参照Kaniel et al.(2008)构建了个人投资者交易不平衡性指标─净交易,以反映投资者股票交易的强度。采用这种交易不平衡性指标来构建投资组合研究个人投资者的交易行为。首先研究个人投资者交易和股票的收益之间的动态关系从而分析投资者的交易策略,然后研究个人投资者净交易的收益预测能力从而分析个人投资者交易的信息含量。本文研究发现:台湾股票市场的个人投资者采用负反馈的交易策略,并且个人投资者在交易中表现出很强的处置效应;个人投资者在交易中的信息含量不足;个人投资者交易中的盈利主要来自两个方面:过度反应和价格冲击。文章最后给出政策建议。     

投资者关注与IPO异象——来自网络搜索量的经验证据

利用谷歌趋势提供的搜索量数据,本文构建了一个投资者关注的直接衡量指标,在此基础上,运用行为金融学里投资者关注的理论,系统解释了IPO市场存在的三种异象。与文献中常见的其他解释变量相比,本文发现IPO前个股网络搜索量对于市场热销程度、首日超额收益和长期表现有更好的解释力和预测力,它可以解释首日超额收益的23%,长期累积收益率的10%以上,结果均十分显著。研究结果表明,投资者关注对资产价格有直接的影响,2009年的新股发行体制改革对首日超额收益的降低起到了明显作用。     

出口开放、地区市场规模和经济增长

报酬递增是跨国或区域经济增长发散的重要动因,而市场范围的大小则决定了报酬递增的程度。本文的实证研究发现,地区市场规模和出口开放程度显著地影响了1970—2000年各省区人均收入的增长速度;在地区差距的形成和演进过程中,国外和地区市场是相互替代的,而一旦控制了市场规模因素,各个省区即呈现明显的收敛趋势。本文根据地理特征构造工具变量,有效地控制了变量的内生性问题。     

指数关联债券——城市公租房建设融资的途径探索

《十二五规划纲要》中提出的五年内建设3600万套保障性住房至少需要投资4万亿元,其中绝大部分需要地方政府融资.针对其中公租房存在的融资瓶颈,本文分析了发行市政债券的必要性,提出发行一种创新型产品——指数关联债券(Index Linked Bond),以促进地方政府的信用建设,改善融资环境.另外,本文量化分析了公租房的造...     

征地留用地安置模式适用范围的定量评价与实证研究

留用地安置模式是20世纪80年代以来,全国各地相继使用的土地征用的安置模式.但留用地安置模式有其特有的适用条件的,不能简单复制.论文的研究目的就是通过定量评价的方式确定留用地安置的适用范围,为各地实施留用地安置模式给出一定的参考.论文就湖南省实施情况的调研结果,采用特尔菲法,对适用条件进行了评价,井以湖南省为例,就不同区域的适宜性进行评价.结果表明留用地安置模式只在城市规划稳定、经济发展水平较高,房地产市场成熟,土地需求较为旺盛的地区实施.     

日本政府投资、民间投资和产业资本收益之间关系的实证分析

本文基于日本的统计数据,利用VAR模型和格兰杰因果关系检验方法,研究政府部门投资、民间部门投资和全产业总资本收益率之间的相互作用。VAR模型分析表明,政府投资对民间投资的影响比较大,两者对全产业总资本收益率的影响都很大且政府投资的影响远远大于民间投资,这些影响关系都较复杂。格兰杰因果关系检验表明,政府投资变化是民间投资变化的格兰杰原因,两者分别是全产业总资本收益率变化的格兰杰原因,而这些变量之间不存在相反方向的格兰杰因果关系。     

Communication,Excess Comovement and Factor Structures

This paper develops a model in which investors communicate before trading in a general equilibrium. Investors repeatedly communicate in a social network but have limited knowledge of the network structure and thus do not fully realize the consequences of their communication and belief updating. As a result, asset returns contain excess comovement and more concentrated factor structures than fundamental values do. The model generates testable empirical predictions that are consistent with the empirical literature on excess comovement in asset returns.     

中国高新技术企业研发溢出与公司股票收益率:基于吸收能力的实证研究

高新技术企业是中国创新体系中的重要创新主体,其研发活动能够在创新系统中形成溢出效应并影响其它企业的创新活动。运用随机前沿生产函数模型估算高新技术企业对外部研发溢出的吸收能力,利用2009-2015年企业的财务数据和股票行情数据,检验了企业对外部研发溢出的吸收能力对其长期股票收益率的影响。结果表明,在长期层面,企业对外部研发溢出的吸收对其股票收益率有正向滞后性影响。同时,在一定时期内,研发投入对企业吸收能力具有显著正向影响。     

Who Plays the Key Role among Shanghai, Shenzhen and Hong Kong Stock Markets？

In this paper we examine the daily frequency stock market indices of Shanghai, Shenzhen and Hong Kong from January 2000 to June 2012, and use the Morlet wavelet coherence model to determine who is playing the most important role in the financial markets of China. We find that there are significant comovements between these stock markets in the medium and long run. This provides investors with opportunities to increase their capital gains. The Hong Kong stock market plays a leading role in the long run, but its leader position is threatened by fast‐growing Chinese mainland stock markets, especially the Shanghai Stock Exchange. Based on our analysis, the following suggestions apply to the Chinese stock markets: establish and improve international and regional finance centers in Chinese mainland; encourage more qualified institutional investors; reposition the market relations among Hong Kong, Shanghai and Shenzhen; and increase deregulation and internationalization to speed up the integration of financial resources.
