As the ever-proliferating rules and enforcement agents of the regulatory state have become increasingly central to contemporary legal systems, they have drawn the close attention of sociolegal scholars who seek to illuminate how regulation actually functions. This volume includes some of the most insightful empirical studies of regulation, both in the United States and in other advanced democratic economies. The articles address the politics of regulatory policymaking and the design of regulatory agencies; patterns of implementation and enforcement; and business responses to regulatory goals and requirements.
