Knowledge transfer costs and dependence as determinants of financial reporting

Abstract This paper examines the circumstances in which financial reporting exists. Jensen and Meckling (1995 ) observe that where there are high knowledge transfer costs, then decentralisation is necessary; and that where decentralisation occurs there is a control problem, which can be addressed by providing a control system. I predict that where there are high knowledge transfer costs there will be a control system; if the control system uses financial reports, these will occur for activities with high knowledge transfer costs. The ability to decentralise is reduced where dependence makes it potentially costly to allow a subordinate to make decisions about the activity. The paper predicts that high dependence will be negatively associated with the existence of financial reports. The results confirm the predictions that financial reports are positively associated with knowledge transfer costs and negatively associated with dependence.     

Asymmetric Information,Asset Allocation,and Debt Financing

We analyze a signaling game where firms' financing announcements convey private information about their prospects but a moral hazard problem exists in that managers may suboptimally invest. Consequently, the attempt to address an asymmetric information problem exacerbates moral hazard. The equilibrium recognizes both imperfect information problems. Additionally, the firm must determine how to allocate funds between two technologies differing in cash flow timing and managerial accessibility. We define an above-average firm's comparative advantage as that technology which is most dominant relative to a firm with lesser prospects and show that the resultant equilibria follow the lines of the firm's comparative advantage. Finally, we show that separation may be achieved costlessly, i.e., with no explicit signaling cost.

银行保险的制度变迁理论分析以及对我国的启示

20世纪80年代以来,无论是一直实施混业经营的欧洲,还是近几年重新走上混业经营之路的美国,银行保险都成为一种潮流和趋势。银行保险业务的产生及发展,既源于微观领域经营环境和竞争环境的变化,也源于宏观领域制度管制的放松和信息技术的迅猛发展,更源于银行保险经济学机理带来的范围经济和协同效益。银行保险作为一种制度创新的产物,更多地体现为从销售渠道创新到业务产品创新,再到组织模式创新的金融一体化的制度变迁过程。本文从制度变迁理论的角度对银行保险的产生动因以及演变发展进行分析,以期对我国银行保险的走向提供借鉴。     

商业银行公司治理机制的发展趋势研究

公司治理机制是现代公司制度的基本架构。从公司制度诞生至今,良好的公司治理机制始终和公司的健康运行密切相关。由于商业银行区别于一般公司的特殊性,构建良好的公司治理机制一直是国际银行业所关注的焦点。本文从公司治理机制的理论和制度两个层面分析商业银行公司治理机制的发展趋势,并探讨这种变化趋势对中国商业银行公司治理改革的借鉴意义。作者认为商业银行应当按照国际会计准则提高信息披露的质量,利用市场竞争的力量来改善公司治理机制,注重外部审计和内部审计力量的结合,注重法律在公司治理机制中的作用,实现商业银行激励与约束机制的创新。     

税收价格论对强化税收征管的现实意义

税收价格论认为税收是纳税人为消费公共品而向政府支付的“价格”,税收征纳双方在本质上是平等的交换关系。借鉴税收价格论,应当以个人为基点,从利益交换关系的角度,赋予纳税人作为交换一方应有的权利。应在整个公共部门经济的全过程中体现税收本质上的平等交换关系,并以法律的形式予以确定和保护。引进税收价格论,对提供新的税收征管思路,强化税收征管工作,具有重要的现实意义。     

我国农村土地制度的产权经济分析

近年来我国农村发生了土地制度的深刻变革,变革的核心是土地产权制度的变迁。这种制度变迁在某种程度上具有帕累托改进的性质,但在某些方面还有待于发展和完善。我国农村土地产权制度建设的思路:以现行产权制度为基础,通过修订和完善,不断发挥现行产权制度的积极作用。     

税务行政处罚的法理探析

法学意义上的税收是一种金钱给付关系。关于税收的法律关系性质有权利关系说和债务关系说两种观点,不同观点之下对于税务行政处罚的法理有不同的分析。事实上,国家和纳税人之间是一种公法意义上的债权债务关系,税务行政处罚是国家对纳税人不按时履行税收合约的一种惩罚。     

Do executive stock option grants have value implications for firm performance?

Consistent with predictions of agency theory, we find direct evidence that executive stock option grants have value implications for firm performance. This inference is drawn from evaluation of various motivations for the use of such grants in executive compensation: value enhancement, risk taking, tax benefit, signaling and cash conservation. We find consistent evidence for the value enhancement motivation to reduce agency costs. As well, they signal for positive price sensitive information. Our results reject the tax benefit and cash conservation motivations. This finding is robust after controlling for the endogenous character of executive stock option grants and other equity-based grants. JEL Classification G32 • J33 • M52
