Does news media affect audit quality? Evidence from variation in the “contagion effect”

Abstract We examine whether negative news media coverage of peer audit firms affects audit quality by mitigating the contagion effect of low-quality audits. We find that when a company issues a restatement, other companies served by the same audit office or within the same city are more likely to subsequently issue a restatement. However, we find that higher negative peer firm news coverage mitigates this contagion effect, particularly when auditors have greater opportunity to improve audit quality (smaller companies) and when media attention amplifies reputational pressures (higher local news intensity). Our findings extend to litigation-related news but not to nonnegative news, suggesting that auditors respond to perceived reputational threats stemming from negative news. Additionally, negative peer news increases auditor attention, consistent with an auditor supply-side effect that improves audit quality. Our findings highlight the media’s role as an informal oversight mechanism.
