Audit firm political connections and PCAOB inspection reports*

We examine the effect of audit firm political connections on the harshness of Public Company Accounting Oversight Board (PCAOB) inspection reports. Relying on Regulatory Capture Theory and Motivated Reasoning Theory, we show audit firm political connections, as measured through PAC contributions, are negatively associated with the harshness of Part I reports. Our results are robust to instrumentation and are not due to movements of personnel between the PCAOB and audit firms or improvements in a firm's audit quality. In supplementary tests, we show the negative relation is stronger when we consider the directed nature of PAC contributions to members of Congress who exercise SEC oversight and robust to alternative measures. Finally, we consider the harshness of Part II inspection reports and find no association with political connections. Collectively, our results suggest audit firm political connections induce favorable influence over Part I findings of PCAOB inspection reports. (c) 2022 Elsevier Ltd. All rights reserved.
