There have been several collaborative research projects of CSD and FRIDE. For example CSD members contributed to the FRIDE workshop on ‘Evaluating international efforts at democracy promotion: concepts, measurement and causality’, held by FRIDE in Madrid in June 2006 (in conjunction with the Stanford Center on Democracy, Development and the Rule of Law, German Marshall Fund of the United States, and Freie Universistät Berlin). CSD members have authored chapters in FRIDE books and papers in the FRIDE Working Paper series. More recently, a jointly produced book on New Challenges to Democratization is under way and under contract to Routledge for publication in 2009. An international seminar sponsored by FRIDE and organised by the Centre for European Policy Studies in Brussels presented and discussed papers representing the goals of this study in June 2008.
