The American Enterprise Institute for Public Policy Research (AEI) is a conservative think tank, founded in 1943. It is associated with neoconservative domestic and foreign policy views. According to the institute its mission is "to defend the principles and improve the institutions of American freedom and democratic capitalism — limited government, private enterprise, individual liberty and responsibility, vigilant and effective defense and foreign policies, political accountability, and open debate." AEI is an independent, non-profit organization. It is supported primarily by grants and contributions from foundations, corporations, and individuals. It is located in Washington, D.C.
AEI has emerged as one of the leading architects of the second Bush administration's public policy. More than twenty AEI alumni and current visiting scholars and fellows have served either in a Bush administration policy post or on one of the government's many panels and commissions. Former United States Deputy Secretary of Defense Paul Wolfowitz is a visiting scholar, and Lynne Cheney, wife of Vice President Dick Cheney and former chairman of the National Endowment for the Humanities, is a senior fellow.
