Governing transnational social problems: public health politics on the US–Mexico border

Governance research suggests that transnational networks are the key to developing and implementing cooperative public policy across borders. I examine this claim through analysing how the US–Mexico Border Health Commission, a policy instrument designed to enhance transnational public health cooperation, developed from idea to law in Mexico and the United States. Despite a long‐standing transnational network, the policy process took over ten years and was contentious, politicized by domestic policymaking in the United States. I show how transnational networked governance intersects with domestic politics and find that the structure of overlap between the two are places where actors promoting state and transnational interests struggle with each other to define public problems in an attempt to shape policy outcomes.
