We examine the relation between corporate governance and firms' information environments. We use the passage of state antitakeover laws in the U.S. as a source of exogenous variation in an important governance mechanism to identify changes in firms' information environments. We find that information asymmetry and private information gathering decreased and that financial statement informativeness increased following the passage of the antitakeover laws. Cross-sectional analyses indicate that the increased level of financial statement informativeness is attributable to firms that are most likely to access equity markets rather than managerial entrenchment, managerial career concerns, or managers' pursuit of the quiet life.

We use a proprietary data set with detailed executive compensation information to examine the relationship between the incentives of the tax director and GAAP and cash effective tax rates, the book-tax gap, and measures of tax aggressiveness. We find that the incentive compensation of the tax director exhibits a strong negative relationship with the GAAP effective tax rate, but little relationship with the other tax attributes. We interpret these results as indicating that tax directors are provided with incentives to reduce the level of tax expense reported in the financial statements.
