Transnational business regulation is increasingly implemented through private voluntary programs—like certification regimes and codes of conduct—that diffuse global standards. But little is known about the conditions under which companies adhere to these standards. We conduct one of the first large-scale comparative studies to determine which international, domestic, civil society, and market institutions promote supply chain factories' adherence to the global labor standards embodied in codes of conduct imposed by multinational buyers. We find that suppliers are more likely to adhere when they are embedded in states that participate actively in the ILO treaty regime and that have stringent domestic labor law and high levels of press freedom. We further demonstrate that suppliers perform better when they serve buyers located in countries where consumers are wealthy and socially conscious. Taken together, these findings suggest the importance of overlapping state, civil society, and market governance regimes to meaningful transnational regulation.
