Information Disclosure and Transparency Ranking System and Firms' Value Deviation : Evidence from Taiwan

We examine whether the implementation of the information disclosure and transparency ranking system (IDTRS) affects frms’ value deviation in Taiwan using the annual reports of the listed companies for the period 2001–2004. Using firms value deviation as a proxy for information disclosure, we find that reducing information asymmetry can allay moral hazard. We also document a significant difference in the level of information disclosure in the years before and after the IDTRS implementation. Stronger information transparency can strengthen investment certainty and lead to less forecasting errors
