Sourcing Under Supplier Responsibility Risk: The Effects of Certification, Audit, and Contingency Payment

Companies that source from emerging economies often face supplier responsibility risks, namely, financial and reputational burdens that the companies have to bear when their suppliers’ engagement in noncomplying labor and environmental practices becomes public.

As a result, our model endogenizes the supplier’s noncompliance probability and connects it with various factors, including the supplier’s intrinsic ethical level that is unobservable to the buyer.
