股票流动性与增发配股费用——来自中国上市公司的经验证据

基于中国上市公司A股公告日在2000年7月1日至2005年4月29日间的增发与配股事件为样本,采用高频交易数据构造的相对有效价差和相对报价价差对股票流动性增发与配股费用进行考察,结果表明股票流动性越高、增发配股费用越低。同时,使用不同费用的代理变量,以及使用Tobit回归以减轻证监会对承销费率管制的影响,均没有改变研究结论。     

生态资源环境公共产权的经济学分析

在产权制度的界定和规范引导下,生态资源经济才能实现环境友好型、可持续为主题的科学发展。历史上“公有地的悲剧”的启示不单是对产权问题的反思,而是通过设立一套巧妙的制度,以达到“量体裁衣”之功效。生态资源环境公共产权的产生是源于其稀缺性及非排他性的特质。但随着计量这种产权成本与收益的难度不断加深,环境资源体系的经济价值就越来越大。必须考虑在有效利用的前提下,重新界定产权来保证市场与主体效率目标的实现。作为现代产权制度体系的最重要的组成部分——资源类产权,它有别于企业产权制度,且它涉及利益主体的范围之广。涵盖的意义也极其深远。本文对生态资源环境这一较为特殊公共物品的产权问题用产权经济学的思维框架进行研究,从政府、企业、市场、制度四个层级,相应提出构建此类公共产权的四层规制模式,以求破解在生态环境规制过程中出现的产权失灵现象及界定不清的困局。     

Testing the null hypothesis of no regime switching with an application to GDP growth rates

This paper presents tests for the null hypothesis of no regime switching in Hamilton’s (Econometrica 57:357–384, 1989) regime switching model. The test procedures exploit similarities between regime switching models, autoregressions with measurement errors, and finite mixture models. The proposed tests are computationally simple and, contrary to likelihood based tests, have a standard distribution under the null. When the methodology is applied to US GDP growth rates, no strong evidence of regime switching is found.

基于产业组织理论视角的顾客转换成本研究

在一定意义上,顾客转换成本可以看作一种特异性投资,便于企业形成一定程度的市场势力,影响同行企业竞争,提升自身绩效,因此顾客转换成本理论成为近年来学术界研究的重要领域之一。本文将基于产业组织理论S-C-P范式的视角对国内外学者在顾客转换成本方面的研究进行分类综述,并对顾客转换成本的未来研究和应用提出了几点展望。     

中国资本市场的中长期动量效应和反转效应——基于Fama和French三因素模型的进一步研究

基于国内外学者对于中国股票市场的动量效应和反转效应的研究,利用1994~2004年中国股票市场的经验数据,借助于Fama和French的三因素模型,对中国股市的动量和反转效应进行解释。研究结果表明,Fama和French三因素模型的解释力度不大。     

Charity registration and reporting: a cross-jurisdictional and theoretical analysis of regulatory impact

Governments increasingly regulate charities to restrict the number of organizations claiming taxation exemptions, reduce charities’ ability to abuse state support, and detect and deter fraud. Public interest theory arguments suggest that regulation could increase philanthropy through enhancing public trust and confidence in charities. Nevertheless, public choice theory argues that regulators seek to maximize political returns, ‘manage’ charity-government relationships, and reduce potential regulatory capture.

We analyse charity regulatory regimes using these two regulatory theories and the relative costs and benefits of different regulatory regimes. Heeding these should reduce regulatory inefficiency and balance accountability and transparency demands against benefits charities receive from regulation.     

物流成本“七宗罪”的冷思考

在国际上,物流业被公认为是继原材料、劳动力之外的"第三利润源泉",是国民经济发展的动脉之一,早在20世纪60年代,美国经济学家彼得.杜克拉就预言,物流业将是各国经济增长的"黑大陆"。眼下物流成本过高,这既是一种市场乱象,又是一种管理乱象和权力乱象,针对物流成本是物流业发展"罪魁祸首"等"七宗观点"进行辩驳,以寻找促使物流业走上可持续发展轨道的对策。     

A theoretical framework of electronic word-of-mouth against the backdrop of social networking websites

This study proposed and tested a theoretical framework that explains electronic word-of-mouth (eWOM) against the backdrop of social networking websites (SNWs), which have gained substantial popularity among travelers. In particular, a United States (US) nationwide online survey was conducted and nine hypotheses were tested. The findings suggest that willingness to share knowledge and switching costs are positively related to eWOM communication. In addition, customer value (utilitarian) has positive relationships with willingness to share knowledge, perceived security, and switching cost, while customer value (hedonic) has positive relationships with willingness to share knowledge and switching costs. Last but not least, the findings indicate that perceived security does negatively impact eWOM. In light of the major findings, the article sets forth strategic implications for travel-related social networking websites.     

Achieving relational outcomes in casual dining restaurants through consumer commitment

The purpose of the study is to identify how we can achieve positive word-of-mouth (WOM) and share of purchases through consumer commitment in casual dining restaurants. This study proposes the theory of organizational commitment and the framework of the relationship development process as the theoretical foundation to identify the antecedents of consumer commitment (i.e. identification, switching costs, and satisfaction), and tests the role of consumer commitment between its antecedents and relational outcomes (i.e. share of purchases and positive WOM). The results of the study support that commitment plays a partial mediating role in the relationship between its antecedents and share of purchases. In addition, commitment exerts a full mediating role on the effects of identification and switching costs on positive WOM intentions, while it plays a partial mediating role between satisfaction and positive WOM intentions. Managerial implications are discussed to maximize delivering relational outcomes based on consumer commitment and its antecedents.     

Does travellers’ casual attribution affect pre-recovery emotions and behavioural intentions? A field study of airline travellers in Malaysia

This study examines the relationship between airline travellers' casual attribution, pre-recovery emotions, and negative behavioural intentions after a service failure and proposes a model for analysing direct effects of airline travellers' casual attribution of stability (failure frequency) and controllability (the extent to which the airline can control the failure) on negative behavioural intentions as well as its indirect effects through pre-recovery emotions. Data were gathered through a survey of airline travellers who experienced a failure in the past six months. The results indicate that both dimensions of casual attribution influenced pre-recovery emotions and negative behavioural intentions, and that pre-recovery emotions were significantly related to negative behavioural intentions. In addition, the results verify the mediating effect of pre-recovery emotions on the relationship between casual attribution and behavioural intentions. These results have important managerial implications.
