The following post comes to us from Ray Ball, Professor of Accounting at the University of Chicago, Sudarshan Jayaraman of the Accounting Department at Washington University, and Lakshmanan Shivakumar, Professor of Accounting at London Business School.
In the paper, Audited Financial Reporting and Voluntary Disclosure as Complements: A Test of the Confirmation Hypothesis, which was recently made publicly available on SSRN, we examine the hypothesis that audited financial reporting and voluntary disclosure of managers’ private information are complementary mechanisms for communicating with investors, not substitutes. More specifically, we test the hypothesis in Ball (2001) that independent verification and reporting of financial outcomes encourages managers to be more truthful and hence more precise in their disclosures. This allows managers to credibly disclose private information that is not directly verifiable, alleviating the problem (Crawford and Sobel, 1982) that private information disclosure as a stand-alone mechanism is uninformative because in equilibrium it is untruthful.
