公司治理强度、审计力度与审计质量

自安然事件以来,公司治理和外部审计的重要性得到了前所未有的重视.本文构建了一个公司所有者与外部审计师之间的博弈理论模型,以分析均衡状态下公司治理强度、审计力度与审计质量之间的关系,并讨论所有者和审计师赔偿责任对博弈均衡的影响.我们特别引入了公司治理成本函数和审计成本函数,并同时考虑了公司所有者和审计师的赔偿责任.在本模型中,公司所有者对公司治理强度的决策和外部审计师对审计力度的决策共同影响审计报告对外部投资者的信息有用性(即审计质量),并最终影响了公司的成交价格.研究得到的主要结论是:(1)均衡状态下公司治理强度的增加有助于提升审计力度和审计质量;(2)所有者赔偿责任的增加只会提高公司成交价格,但不会影响博弈均衡和均衡状态下的审计质量;(3)审计师赔偿责任的增加并不一定导致所有者降低公司治理强度,且只有在特定情况下才能提升审计力度和审计质量.

Corporate Governance Strength,Audit Effort and Audit Quality

The importance of corporate governance and external audits has been repeatedly emphasized worldwide since the exposure of the Enron scandal in 2002.With reference particularly to research published by Pae and Yoo in 2001,this paper constructs a game theoretical model primarily featuring a firm's owner(who intends to sell a solely held firm) and an external auditor(who is hired by the owner to issue an audit report).We further introduce into the model cost functions for corporate governance strength and audi...
