Using social network analysis, we find that director interconnections—established through overlapping board memberships—are associated with audit fees. Our findings reveal an extensive, yet fragmented director network, where higher centrality positions correlate with increased audit fees. This suggests that director connections strengthen the demand for audit effort, leading to higher audit fees. Furthermore, we show that director centrality moderates the positive relationship between firm complexity, financial risk, and board independence with audit fees.
