|November 2017||On the Economics of Audit Partner Tenure and Rotation: Evidence from PCAOB Data|
with Luzi Hail, Christian Leuz: w24018
This paper provides the first partner tenure and rotation analysis for a large cross-section of U.S. publicly listed firms over an extended period. We analyze the effects on audit quality as well as economic tradeoffs related to partner tenure and rotation with respect to audit hours and fees. On average, we find no evidence for audit quality declines over the tenure cycle and little support for fresh-look benefits after rotations. Nevertheless, partner rotations have significant economic consequences. We find increases in audit fees and decreases in audit hours over the tenure cycle, which differ by partner experience, client size, and competitiveness of the local audit market. More generally, our findings are consistent with efforts by the audit firms to minimize disruptions and audit fa...

We find that market responses to unexpected earnings increase significantly following the introduction of the PCAOB inspection regime. Corroborating these findings, we also ...
