The purpose of this study is to empirically examine the effects of canceling the lower bound of audit fees on audit fees and auditor change. The results indicate that audit fees decreased, but not significantly. In addition, this study finds that canceling the lower bound of audit fees significantly increased the probability for firms to change auditors. Finally, this study also reveals evidence that the change of the ratio of cash flow from operating activities, management change, and qualified opinion have significant effect on the probability for firms to change auditor.
