In this paper we report the results of experimental markets designed to test a disclosure model based on the models of Dye [1985] and Jung and Kwon [1988]. These authors show that when receivers of information do not know whether senders possess private information, the senders will not fully disclose their private information. Their models were motivated by the discrepancy between the theoretical predictions for voluntary disclosures and empirical results. In the theoretical area, Grossman [1981] and Milgrom [1981] predicted that private information will be fully disclosed when disclosures are credible and receivers know the holder has private information; agents disclose to identify themselves as not possessing the worst possible information. Watts [1977] argued that voluntary disclosure will occur because of market pressures and the threat of regulatory intervention. Beaver [1977; 1988] described how auditing and legal liability may induce full disclosure. Nevertheless, empirical research indicates full disclosure is not always observed (e.g., Penman [1980] and Seligman [1986]).

We provide results from an experiment designed to assess whether mandatory rotation and/or retention of auditors increases auditors' independence by reducing their willingness to issue reports biased in favor of management. Auditors' reporting is compared across the following four regimes: one that does not require either rotation or retention, a second that requires retention only, a third that requires rotation only, and a fourth that requires both rotation and retention. We find that the rotation requirements in the third and fourth regimes decreased auditor‐subjects' willingness to issue biased reports, relative to the two regimes in which rotation was not imposed. In these other two regimes, however, many manager‐subjects voluntarily retained the same auditor‐subjects over multi‐periods. While the long running interactions between manager‐ and auditor‐subjects resulted in more favorable reports by auditor‐subjects (a lower level of independence), the established relationships also induced manager‐subjects to make higher investments.
