股权分置改革上市公司并购格局变化与对策研究

本文认为,并购是公司资本组织方式和经济制度相互博弈的一种制度变迁。在股权分置时代上市公司的并购行为存在制度性缺陷,股权分置改革将会对上市公司的并购市场产生重大影响,并导致并购格局的重整。各方利益相关者必须对此变革采取相应对策,通过新的博弈实现最优利益均衡。     

Estimating Krugman’s Economic Geography Model for the Spanish Regions

This paper estimates Krugman’s (J Polit Econ 99:413–499, 1991) economic geography model using data from the Spanish NUTS 3 regions. The econometric formalization endogenously determines wages in a region as a function of income and wages in other regions. The specification adopted also allows us to study the relation between the agglomeration of economic activity, increasing returns and market access. The first result obtained is that the Spanish economy exhibits a spatial wage structure: wages in a region are positively determined by income and wages in neighboring regions. In second place it is found support for the structural relations of the underlying theoretical model, indicating the importance of scale economies and transport costs in shaping the Spanish economic geography.     

信誉的价值:以网上拍卖交易为例

本文使用网上拍卖交易数据,就卖者信誉对市场交易的影响进行了实证研究。我们发现,卖者的信誉评价一方面影响物品成交的价格,另一方面还对物品拍卖成功的概率有着显著的正面影响;但相对来说,卖者的信誉评价对后者的效果比对前者要更显著。这是本文的主要发现。该结果验证了在一个没有政府干预、近乎自由放任的“虚拟”市场上信誉机制的积极作用。     

融资成本、寻租行为和企业内部资本配置

本文构造了一个两层次委托代理模型,强调了外部资本市场和内部资本市场之间的相互作用,分析表明,资本配置扭曲和资本使用效率低下的关键是外部资本市场运作不完善对企业内部管理者的寻租行为的影响。本文的分析表明,融资成本偏低的外部资本市场不仅会促使企业CEO过分扩大融资规模,而且会加剧企业内部管理者的寻租行为,导致资本配置不当、投资缺乏效率的不良后果。本文的政策含义是,必须改变融资成本偏低的现状,并加强公司治理结构建设,才能解决我国企业融资过热、资本使用效率低下等一系列问题。     

我国建筑业市场进入壁垒为何失效

我国建筑业具有典型的分散型产业组织特征,市场集中度偏低的主要原因在于进入门槛较低。规模经济、产品差异化、必要资本量、绝对费用等结构性进入壁垒没有起到限制企业进入的作用,而企业资质管理作为一种市场准入制度,虽然构成了建筑市场最主要的进入壁垒,但在等级设定、专业划分等方面缺乏长期性和稳定性,长期来看对于抑制过度进入和优化产业结构的作用比较有限。     

农业保险理论研究述评及展望

农业保险问题一直是保险学和农业经济学领域关注的热点问题,国内外学者对此做了大量研究。国外文献研究了农业保险市场失灵、政府介入农业保险市场的原因和农业保险需求,国内文献主要研究了农业保险的政策属性、财政补贴、农业保险需求和供给。这表明农业保险研究仍局限于新古典经济学的研究范式,把农业保险组织视为黑箱。本文在梳理国内外文献的基础上提出了一个新的研究视角——组织视角,并构建了农业保险组织研究的理论框架。     

我国企业慈善行为的市场反应——基于汶川地震捐赠数据的实证检验

本文以136家中国上市公司为样本,分析了汶川地震后资本市场对企业发布捐赠公告的市场反应,与对照组企业相比,样本中的企业的7天累计超额收益率显著为正.但是,当把样本划分为政府控股企业和私人企业两类后,本文发现两类企业在捐赠行为上存在明显的差异,Godfrey的"慈善捐赠只有被看作是企业社会责任的真实表达时才可以提高企业价值"的观点,在政府控股企业并不适用.     

New market socialism: a case for rejuvenation or inspired alchemy?

The aim of this paper is to examine the relative merits anddrawbacks of two recent models of market socialism proposedby Bardhan and Roemer. This is done, first, by putting thesemodels into the perspective of the history of economic thought.Thus, after presenting the basic elements of the early Langemodel as well as the Austrian and ‘new information economics’critiques, the necessary comparisons and contrasts are madeto see what new light these new models bring into this debate.In addition, the internal consistency and coherence of thesemodels is checked in terms of their own proclaimed goals. Last,a more radical methodological critique is provided.     

Adam Smith and the division of labour: is there a difference between organisation and market?

The paper claims that, in The Wealth of Nations, the divisionof labour refers simultaneously to two different things: a socialdivision of labour and an organisational division of labour.The central point is that the organisation of work (the organisationaldivision of labour) in the firm is the logical counterpart ofthe social division of labour, and that these reflect two inseparableaspects of the process of the division of labour. Smith is thusconcerned with organisations as well as with markets, each functioningaccording to the same principle. Hence, Smith does not believethat the organisational and the social divisions of labour arefundamentally different, although he does recognise some variationbetween them and describes different states of the divisionof labour within the firm, liberal and capitalist.     

市场拥挤、财政支出和税后资本平均产出关系分析

税后资本平均产出的高低对私人部门投资决策产生重要影响,但是我国自1994年分税制改革以来,税后资本平均产出处于不断下降趋势,与此同时,财政支出规模呈不断扩大趋势。本文在财政支出解决市场拥挤框架下分析了财政支出对税后资本平均产出的影响,在理论分析中,说明财政通过增加支出缓解市场拥挤来影响税后资本平均产出,其影响程度由税率、财政支出的产出弹性、市场拥挤程度决定。在实证分析中,计量检验了世界范围内和中国地方政府财政支出对税后资本平均产出的影响,并结合现实对计量结果给予解释。
