ABSTRACT
International law obliges states to fight trafficking in human beings via different means, not only via criminal law but also via preventive measures more generally. In addition, they should engage in cooperation with civil society in implementing these measures. In this contribution, I address the question of how to evaluate whether and to what extent national prostitution policies are effective in preventing human trafficking. After addressing the pitfalls of using numbers of human trafficking as an indicator of effectiveness, I propose an alternative model of evaluation, grounded on the theory of the social working (TSW) of rules and insights into regulatory intermediation. This model will be applied to the Dutch policy concerning the prevention of human trafficking in prostitution.
