企业边界与产业组织的动态演化——基于企业边界二元分析范式的综合解释

对企业边界的主流研究存在着运用交易费用理论和企业能力理论的两大范式,但均有其局限性,即停留在短期的静态分析和局限于企业层面。本文在这两大范式的基础上,把短期、静态分析推进到长期、动态分析,并着力从产业层面揭示企业边界的动态演进机制,试图实现企业边界二元范式的新综合。二元范式的综合解释说明,交易费用与企业能力,企业边界与产业边界之间是一种共同演化关系。     

基于企业理论的“农民工”权益保护研究

随着农村劳动力的过剩,很多农民选择了城市务工,但是损害农民工权益的现象屡屡发生。研究"农民工"权益在企业的保护方案,首先要解决企业理论与"三农"政策的内在一致性。从原有企业理论出发,可以建立社会网络产业结构信息系统、各地区各行业"农民工"权益信息系统,给不同区域企业与"农民工"传递"农民工"权益及其变动信息,保护"农民工"的权益。     

基业长青的企业本质: 一种基于广义虚拟经济视角的解释

制度经济学的企业理论在探寻企业的本质时,将企业抽象为市场的对应物,抹杀了现实中不同企业之间存在的差别(异质性),难以理解企业之间的竞争及企业是如何成长.战略管理学则倾向于重视这种差别,并以此为基点从理论上阐释了企业是如何获取并持久保持竞争优势以促进企业成长,但忽视了企业的同质性.本文则从广义虚拟经济二元价值容介态的视角...     

所有权结构、股价波动异步性与上市公司现金持有价值

股价中包含了较多的企业特质信息或者信息噪声都可能导致企业股价异步性现象。股权集中程度越高,其股价吸收企业特质信息的效率越低。借鉴Faulkender和Wang(2006)以及Dittar和Mahrt-Smith(2007)提出的衡量现金持有价值的方法,本文系统检验了2003～2006年我国A股上市企业的股价异步性与资金效率的关系。实证检验发现,其他情形相同的情况下,股价异步性与现金持有价值呈显著正相关关系,然而这种显著的正相关关系主要体现在股权分散的企业和非国有企业中。可见,所有权结构安排和股权性质是影响股价信息含量以及股价在资本配置过程中的发挥基础性作用的决定因素。     

避税行为干扰了市场对信息的理解吗

避税决策是避税成本与避税收益的权衡。从收益上看,避税可以为企业带来现金流的节约,提升企业价值。但避税行为也会带来许多显性和隐性的成本,因此,避税行为对企业价值的最终影响取决于避税行为是否能被市场参与者正确、迅速地理解。以2005～2007年中国证券市场A股公司为样本的实证分析表明,避税行为由于具有复杂性和专业性,会干扰...     

论经济学的边界

有经济学家认为经济学的基本逻辑可以解释人类所有的行为,他们运用经济行为模式对其他学科的传统“领地”簪越扩张,进行“经济学帝国主义”,试图用经济学的基本分析法方代替所有社会科学。但是随着经济学的扩张,经济学的解释力减弱,扩张的边际收益递减;同时,要求的理论创新加大,即边际成本递增。当两者相等时就达到了一种扩张的均衡,由此可以确立经济学的合理边界。     

新新贸易理论及其进展

21世纪初诞生的新新贸易理论突破了新古典贸易理论和新贸易理论以产业为对象的研究范畴,将分析变量进一步细化到企业,以异质企业的贸易投资作为研究重点.企业异质性有两种形式,由于产业内部不同企业生产率的差异而产生的异质性以及企业组织形式差异而产生的异质性,这两种异质性紧密相连.新新贸易理论通过异质企业贸易模型的建立,阐明了现实中只有部分企业选择出口和对外直接投资的原因;通过企业内生边界模型的建立和拓展,将产业组织理论和契约理论的概念融入贸易模型,很好地解释了公司内贸易模式,并在企业全球化生产研究领域进行了理论创新.     

The impact of earnings expectations on corporate downsizing

Research Summary: We propose that due to financial market pressures, managers are forward‐looking in their search and decision processes and focus on meeting performance targets set by the financial community. Using panel data on S&P 100 companies, we find that pressure felt by management to meet the analyst consensus earnings estimate influences the extent of corporate downsizing. Moreover, our results show that high levels of institutional investor stock ownership and CEO power attenuate managers’ sensitivity to financial market pressures, while high levels of analyst coverage increase their sensitivity. Managerial Summary: In this study we examine how financial market pressures influence managers’ downsizing decisions. We argue that investment analysts’ earnings estimates represent important performance targets to which managers aspire. If firms fail to meet analysts’ expectations, the stock price will suffer. This study shows that managers utilize corporate downsizing to address the potential shortfall between a firm's future performance and the analyst consensus earnings estimate. In addition, we find that managers’ concerns over meeting analysts’ earnings estimates are influenced by various contextual factors such as institutional investor stock ownership, CEO power, and high levels of analyst coverage.     

Do investors actually value sustainability? New evidence from investor reactions to the Dow Jones Sustainability Index (DJSI)

Research Summary: Research exploring investor reactions to sustainability has substantial empirical limitations, which we address with a large‐scale longitudinal financial event study of the first global sustainability index, DJSI World. We examine investor reactions to firms from 27 countries over 17 years that are added, deleted, or continue on the index. We find that once relevant controls and comparisons to observationally equivalent firms beyond the index are included, DJSI events have only limited significance and/or materiality. Nonetheless, investors' valuation of sustainability around the world has evolved over time, involving diminishing reactions to U.S. firms and increasing benefits, particularly of continuation on the index, over time. The study highlights the importance of careful analysis and longitudinal global samples in making inferences about the financial effects of social performance. Managerial Summary: The debate about how investors perceive corporate social responsibility (CSR) predates Milton Friedman's famous statement that the only social responsibility of business is to increase profits. Although extensive research has studied whether sustainability contributes to financial performance, we have yet to understand whether investors believe it pays off. This financial event study of reactions to the addition, continuation, and deletion from DJSI World, the first global sustainability index, shows that investors care little about DJSI announcements. Nonetheless, there is some evidence that global assessments of sustainability are converging and that investors may increasingly be valuing continuation on the DJSI, suggesting that firms may gain at least limited benefits from reliable sustainability activities.
