This paper presents a general equilibrium model for the production, trafficking, and consumption of illegal drugs which endogenously determines relative prices and quantities. The model is calibrated to characterize the market for cocaine and is used to analyze the effects of three types of policies: making the illegal activities riskier, increasing the penalties for conducting illegal activities, and legalizing previously illegal activities. Assessing the effects of these policies using the powerful tool of a general equilibrium model provides illuminating (and in cases surprising) results.

This book presents evidence that drug policies impose high costs on poor transit and producer countries. It argues that, in the face of great uncertainty about the benefits of alternative drug policies, those with lower social costs should receive greater emphasis.
