The Inter-American Dialogue (IAD) just won this year's Prospect Magazine Best Think Tank of the Year Award for best US think tank.
In the annual University of Pennsylvania think tank rankings, IAD is rated as the 37th best think tank in the US. It will be interesting to see next year's UPenn rankings to see if IAD moves up.
IAD is a Washington, DC-based think tank focusing on Western Hemisphere affairs. It celebrated its 30-year anniversary in 2012.
The other thinks tanks on the "shortlist" for best US think tank were Carnegie Endowment for International Peace (CEIP), Foreign Policy Research Institute, and Institute for Women's Policy Research.
Last year, in the best US think tank category for 2013, Third Way was the winner, and Brookings Institution was the runner up.
Carnegie Europe won the best European think tank of the year award, the Institute for Fiscal Studies won the best UK economic and financial affairs think tank, Chatham House won the best UK energy and environment think tank, and European Council on Foreign Relations (ECFR) won best UK international affairs think tank. IPPR won the award for UK's best social policy think tank.
The "think tank to watch" award was won by Higher Education Policy Institute (HEPI), which is UK's only independent think tank devoted to higher education.
