Abstract: Using proprietary data, we analyze how a variety of audit composition and team characteristics are associated with audit effectiveness and efficiency. We find that more time allocated prior to the final phase of the audit is associated with more effective audits. We also decompose the time allocation and experience characteristics of the core audit engagement team across the following roles: lead partner, engagement quality reviewer, and other experienced team members (comprised of other audit partners, directors, senior managers, and managers). While the lead partner time and experience are not associated with audit effectiveness, we find that more time spent and experience of other experienced team members are associated with more effective audits. Many of the characteristics that improve audit effectiveness do not improve efficiency, but rather are costly to the client, with one exception. Overall, our analysis highlights several cost-benefit tradeoffs to improving audit effectiveness.
The economic research fellows and staff economists generate high-quality working papers that inform the oversight activities of the PCAOB and are disseminated to stimulate discussion and critical comment to the benefit of the public. Working papers are preliminary materials that have not been approved by the Board and reflect only the views of the author(s).
The research topics of economic research fellows, including a description of any nonpublic data sets required for research, are presented to the Board for approval and research papers are reviewed to confirm that the topic of the paper is consistent with the researcher's proposal. That review does not, however, encompass an evaluation of the conclusions reached by researchers.
