Regression was used with panel data to analyze the relationship. The result showed a direct relationship between perceived market value of firms and level of disclosure.

Besides the significant relationship between market value and corporate governance, a relationship was found between Corporate Governance Index and two variables: Tobin’s q and Return On Assets.
