Infrastructures—whether physical, informational, digital—can have regulatory‐type effects. These include requiring, preventing, channeling, enabling, and nudging particular human and social behavior. Infrastructures also interact or compete with law. In these ways, infrastructures have major effects on social relations, identities, roles, capabilities, and possibilities. In today‘s world, infrastructures‐as‐regulation, and the enabling and controlling legal technologies and practices, are frequently transnational. As such they are deeply connected to other processes of globalization, and may in significant parts be beyond the control of most states or national public processes. We study these phenomena in an incipient research project on Infrastructures‐as‐Regulation (InfraReg) based at New York University School of Law, with collaborators around the world. The panel discusses major themes of the project in an open roundtable conversation that encourages participation by the audience.
