Public Interest or Policy Diffusion : Analyzing the Effects of Massage Therapist Municipal Licensing

Massage therapy is widely licensed by the states. However, municipalities also often passed massage therapist licensing, motivated by preventing prostitution. Using a novel dataset on municipal licensing and crime data from the FBI, we test if local massage therapist licensing reduced prostitution. We also test a policy diffusion hypothesis, in which cities pass responsive massage therapist licensing. We find that municipal massage therapist licensing does not lead to a reduction in prostitution, but we find support for the policy diffusion hypothesis, with municipalities up to 65% more likely to pass responsive licensing within three years of their neighbor doing so
