A central question in drug policy is how control e orts should
be divided among enforcement, treatment, and prevention. For this
regard, Caulkins and Tragler [11] developed a model to study how
the mix of control e orts should vary dynamically over the course of
an epidemic. In this thesis, the initiation function of the model of
Caulkins and Tragler [11] is changed to a logistic growth function and
analysed for comparison. Due to some necessary adjustments of the
parameters, a precise comparison turns out to be hardly possible. The
results of the di erent sensitivity analyses regarding some parameters
and their comparison between both models are presented.

Dynamic programming/optimal control: applications to drug policy; Judicial/legal: crime and drug policy. Model comparison: power and logistic function
