The Manhattan Institute for Policy Research (renamed in 1981 from the International Center for Economic Policy Studies) is a conservative American think tank established in New York City in 1978 by Antony Fisher and William J. Casey. The organization describes its mission as to "develop and disseminate new ideas that foster greater economic choice and individual responsibility". Its message is communicated through books, articles, interviews, speeches, op-eds, and through the institute's quarterly publication City Journal. According to the 2014 Global Go To Think Tank Index Report and Policy Advice (Think Tanks and Civil Societies Program, University of Pennsylvania), the Institute is number 39 of the "Top 60 United States Think Tanks".
