Sarbanes-Oxley Act Strengthens Audit Quality, Boosts Fees for Specialized Auditors
The study looked at how different types of auditors affect the quality of audits before and after the Sarbanes-Oxley Act (SOX). They found that after SOX, audit fees increased for certain auditors, but the quality of audits did not always improve. Specifically, audits by local and new auditors showed a decrease in errors, while audits by Big 4 and industry specialist auditors did not show the same improvement. This shows that the impact of SOX on audit quality varies depending on the type of auditor.
