The AEI-Brookings Joint Center for Regulatory Studies, established in response to growing concerns about understanding the impact of regulation on consumers, business, and government, is no longer in existence. The primary purpose of the Joint Center was to hold lawmakers and regulators accountable for their decisions by providing thoughtful, objective analyses of existing regulatory programs and new regulatory proposals. AEI-Brookings Joint Center archives and more recent work is available at http://www.reg-markets.org/. AEI work is available at http://www.aei.org, while Brookings work, is available at http://www.brookings.edu.
