I’m currently working on a paper about when demobilization occurs after civil war without international intervention. There doesn’t seem to be a lot of rigorous political science literature (in English) on the reasons that some countries implement DDR after conflict and others don’t, or whether peacekeeping makes DDR more likely to succeed. At a more basic level, I also haven’t found a comprehensive list of DDR programs and their outcomes.
Nicholas Sambanis and Jonah Schulhofer-Wohl have a good overview of the conceptual problems with measuring demobilization, and there have been some interesting studies focusing on the individual-level effects of DDR, like Blattman & Annan in Liberia [PDF], Humphreys & Weinstein in Sierra Leone [PDF], Gilligan, Mvukiyehe & Samii in Burundi [PDF], and D’Aoust, Sterck & Verwimp in Burundi [PDF]. Any other recommendations addressing the issues above? Suggestions in English and French are welcome.
