Monitoring the monitors

Outsourcing firms increasingly rely on social auditors to provide strategic information about the conduct of their suppliers to manage the reputational risks that can arise from dangerous, illegal, and unethical behavior at supply chain factories. But little is known about what influences auditors' ability to identify and report poor supplier conduct. We find evidence that private supply chain auditors' reporting practices are shaped by several social factors including their experience, gender, and professional training; their ongoing relationships with suppliers; and the gender diversity of their audit teams. By providing the first comprehensive and systematic findings on supply chain auditing practices, our study suggests strategies companies can pursue to develop more credible monitoring regimes to reduce information asymmetries between themselves and their suppliers.
