Do school ties between auditors and client executives influence audit outcomes?

We identify connected auditors as those who attended the same university as the executives of their clients. Using manually collected data from China, we find that connected auditors are more likely to issue favorable audit opinions, especially for financially distressed clients. Moreover, companies audited by connected auditors report significantly higher discretionary accruals, are more likely to subsequently restate earnings downward, and have lower earnings response coefficients. Lastly, connected auditors earn higher audit fees. Collectively, our evidence suggests the impairment of audit quality when auditors and client executives have school ties and the presence of social reciprocity derived from school ties.
