The article critically assesses three major alternatives to the prevailing policy of criminalization. It evaluates alternative approaches--decriminalization, legalization, and a two-track model differentiating between street and indoor prostitution - using the criteria of public preferences, efficient use of criminal justice resources, and harm reduction. It determined that the two-track model had advantages over decriminalization and legalization, because it satisfied those criteria. Essential ingredients of the policy include: (1) redirecting control efforts from indoor to street prostitution; (2) gender-neutral law enforcement; and (3) providing support services and assistance for persons who want to leave prostitution. Most effective implementation of the policy would require changes in all three areas simultaneously. The article also examines the case for paying more attention to the demand side of prostitution.
