    Title:
    Investigating Inspection Risk: An Analysis of PCAOB Inspections and Internal Quality Reviews
    Practical Implications:

    This paper complements and extends the limited extant research on inspection risk by clearly defining the construct and providing empirical evidence consistent with its existence and impact on auditors’ planning decisions. The authors contend that while auditors may perceive that PARs do not influence effort or fees, both PARs likely cause auditors, perhaps unconsciously, to increase effort and fees.

    Purpose of the Study:

    The authors report the results of an experiment that examines how auditor anticipation of the two primary external and internal post-audit reviews (PAR), specifically, U.S. Public Company Accounting Oversight Board (PCAOB) inspections or public accounting firms’ internal quality reviews (IQRs), affects auditors’ perceptions of overall engagement risk, as well as effort and pricing decisions. The authors define inspection risk as “the risk that an auditor or audit firm will suffer harm as a result of a PAR.” Although the current PAR regime has been in place for over ten years, there is little empirical evidence concerning whether, and to what extent, anticipating a PAR impacts auditor behavior, and whether the effects of anticipating a PCAOB inspection or IQR differ. IQRs also remain largely uninvestigated, despite researchers beginning to investigate external PCAOB reviews. 

    Design/Method/ Approach:

    To investigate how PAR salience affects auditors’ judgments and decisions, the authors conduct a 1 x 3 between-subjects experiment using a number of high-level auditors as participants. They manipulate PAR salience as PCAOB inspection salient, IQR salient, or no explicit expectation of a PAR. 

    Findings:
    • The authors find that PAR salience yields greater perceived overall engagement risk, even after controlling for traditional engagement risk-related factors, implying that auditors perceive inspection risk as incremental to these factors.
      • In addition, increased PAR salience results in greater audit effort and fees, consistent with an inspection risk component.
    • The authors find that both PARS yield higher fees, with the higher fees attributable only to greater effort, rather than an “inspection risk premium.”
    • PCAOB inspection results are more visible than IQRs, and partners perceive that PCAOB inspections can yield greater negative consequences for themselves and their firms; therefore, the authors find that PCAOB inspection salience involves larger increases in perceived overall engagement risk and audit effort than does IQR salience.
      • However, the authors do not find differences in audit fees between PCAOB and IQR salience.
