The Federalism Project
Publications Events

The AEI Federalism Project conducts and sponsors original research on American federalism, with particular emphasis on federal and state business regulation, legal developments and the role of the courts, and the prospects for rehabilitating a constitutional federalism that puts states in competition for productive citizens and businesses. Through its AG Watch, the Federalism Project monitors and comments on the increasingly active role of state attorneys general.

The AEI Federalism Project disseminates its research results and opinions through frequent conferences and other public events; through the Federalism Outlook, a newsletter written by the Project’s Director, Michael S Greve; through its website; and through books and publications in scholarly journals.


Federalism problems and arrangements vary considerably, depending on the regulatory subject-matter. AEI's Federalism Project critically examines the roles of state and federal regulators in antitrust regulation, internet taxation, banking regulation, securities and corporate law, environmental law, and education and health policy. Our special emphasis is on questions of federal preemption and, in cooperation with the AEI Liability Project, on state and federal liability law.
