My current research is sponsored by Brottsoffermyndigheten and focuses on how different countries work against human trafficking. The background for this is a UN report from 2009 that suggests that the problem is approached in very different ways. At the same time, there are few studies that can describe and explain these differences. For that purpose, a comparison is made between six countries of origin and destination with respect to different functions (detection, prevention, protection, crisis management, consequence management, response) and from the new institutionalism perspective.
