Noise traders,firm-specific uncertainty and technical trading effectiveness

This is the first study to document evidence of technical trading effectiveness at firm level in the Chinese A-share market by investigating the relationship between excess profits of technical trading rules and firm-specific characteristics. Our results reveal that firms with higher excess profits from technical trading have more noise traders and higher institutional ownership and that those firms tend to be growth firms with lower liquidity and higher firm-specific uncertainty. Further analysis shows that the profitability of technical trading rules is unsustainable and the excess profits of the highest technical trading profit quintile portfolio disappear in the following year.     

企业边界人员的私人关系与企业绩效——基于中国市场数据的元分析检验

企业边界人员与外部利益相关者发展私人关系是新兴市场中的普遍现象，但是“私人关系”是否真的会提升企业绩效？当前文献对此问题并未给出一致结论。文章基于105篇使用中国市场数据的中英文文献，运用元分析技术（Meta-Analysis)考察了私人关系对企业绩效的影响，并分析了企业所处的制度环境和市场环境，企业的生命周期、规模、所有制形式等内部特征对上述影响的调节作用。通过对392个效应值的集成分析，文章发现，尽管私人关系确实能提升企业绩效（ｒ=0.167），但是不同层面的私人关系（政治联系和商业联系）对不同类型的企业绩效（财务绩效、运营绩效和战略绩效）所产生的影响存在差异。同时制度环境、市场环境、企业特征均会显著地调节私人关系对企业绩效的影响。上述结论为新兴市场中的企业如何将私人关系转化为企业绩效提供了指导。

“品牌触角”管理——中小型服务企业的品牌运作之道

服务业,区别于制造业、建筑业,其最大的特点就是“以人为本”,在品牌运作上有区别于其他产业的明显特征。中国中小企业中的服务企业如何发展品牌的解决之道——即“品牌触角”管理。品牌触角在中小型服务企业中,融资困难是普遍存在的现象,而在以往的品牌管理理论中,强调的是通过大众传媒的方式建立品牌,广告、公关、新闻策划、事件营销成了发展品牌的必经之路。但是,对于一个历史不过数年,职员不过数十人的中小型服务企业来说,以上的品牌运作方式无疑是一种冒险行为,真所谓“做品牌做得不好是找死,不做又无异于等死”。品牌,对于中小型服务…     

Identifying “best” applicants in recruiting using data envelopment analysis

Selecting the most promising candidates to fill an open position can be a difficult task when there are many applicants. Each applicant achieves certain performance levels in various categories and the resulting information can be overwhelming. We demonstrate how data envelopment analysis (DEA) can be used as a fair screening and sorting tool to support the candidate selection and decision-making process. Each applicant is viewed as an entity with multiple achievements. Without any a priori preference or information on the multiple achievements, DEA identifies the non-dominated solutions, which, in our case, represent the “best” candidates. A DEA-aided recruiting process was developed that (1) determines the performance levels of the “best” candidates relative to other applicants; (2) evaluates the degree of excellence of “best” candidates’ performance; (3) forms consistent tradeoff information on multiple recruiting criteria among search committee members, and, then, (4) clusters the applicants.     

State-owned enterprises going public The case of China

Public listing is a key reform measure for large state‐owned enterprises (SOEs) in China. We find evidence that public listing lowers state ownership significantly, lessens firms’ reliance on debt finance, and allows firms to increase capital expenditure, at least temporarily. We also find that ownership structure affects post‐listing performance. However, we find no statistical evidence of a positive effect of public listing on firms’ profitability. We suggest alternative interpretations of the last finding.     

论地方性法规公信力的构建

法的公信力是法所具有的为社会公认、被社会成员自觉遵守、以国家强制力保证执行的力量.法的公信力对于建设法治社会具有至关重要的作用.地方性法规是我国法律体系的重要组成部分,但是存在着公信力不足的问题.构建地方性法规的公信力,需要行为和观念的统一,需要从立法、执法、司法等各个环节加以解决.     

Trade, product cycles, and inequality within and between countries

Abstract.  This paper incorporates Northern product innovation and product‐cycle‐driven technology transfer into the continuum‐of‐goods Heckscher‐Ohlin model. The creation of very skill‐intensive goods induces the North to transfer production of older, less skill‐intensive goods to the South. These relocated goods are the most skill intensive by Southern standards. Hence, product cycles raise the relative demand for skilled workers and thus wage inequality within both regions. This runs contrary to the Stolper‐Samuelson theorem, but accords well with the fact that wage inequality has risen in both Northern and Southern countries. Moreover, product cycles increase income inequality between countries. JEL classification: F1     

国家行为与产权：一个新制度经济学的分析框架

早期的产权理论侧重于微观层次的分析，较少考虑中观（利益集团）及宏观层次（国家）对产权结构形成的影响及不同层次产权的交互作用的机制。文章从新制度经济学关于国家的定义入手，通过对个体权力与国家、集体行动与国家以及法治化社会与国家的三个层次的分析，提出建立产权制度分析的国家模型，从而论证国家与产权制度变迁的关系。
