The Think Tanks and Civil Societies Program (TTCSP) of the Lauder Institute at the University of Pennsylvania conducts research on the role policy institutes play in governments and civil societies around the world. Often referred to as the “think tanks’ think tank,” TTCSP examines the evolving role and character of public policy research organizations. Over the last 26 years, the TTCSP has developed and led a series of global initiatives that have helped bridge the gap between knowledge and policy in critical policy areas such as international peace and security, globalization and governance, international economics, environmental issues, information and society, poverty alleviation, and healthcare and global health. These international collaborative efforts are designed to establish regional and international networks of policy institutes and communities that improve policy making while strengthening democratic institutions and civil societies around the world. The TTCSP works with leading scholars and practitioners from think tanks and universities in a variety of collaborative efforts and programs, and produces the annual Global Go To Think Tank Index that ranks the world’s leading think tanks in a variety of categories. This is achieved with the help of a panel of over 1,900 peer institutions and experts from the print and electronic media, academia, public and private donor institutions, and governments around the world.
