The "Incomplete Revelation Hypothesis" and Regulating the Manipulation of Financial Reporting

The phenomenon of mispricing that the security market under-reacts or overreacts to fundamental information is beyond explanation just by "efficient m arket hypothesis",which assumes that the market prices fully reflect all public ly available information. Based on "noise rational expectation" model and empiri cal economics,the theory of "incomplete revelation hypothesis" (IRH) argues tha t it is the extraction cost of information that results in mispricing. By using this theory,it is possible to interpret and predict many of the anomies and tes ts of these predictions can also be provided. The authors of this article show t hat the theory is very useful in the analysis of the information and supervision and regulation of the market.
