When the Rhode Island legislature inadvertently decriminalized indoor prostitution in the state from 2003 to 2009, it proved beneficial to UCLA public policy professor Manisha Shah.
Shah and her co-author Scott Cunningham of Baylor University examined data from that period, becoming the first social scientists to evaluate the decriminalization of prostitution using a natural experiment.
During those seven years the state saw a large decrease in rapes and a large reduction in gonorrhea incidence for men and women, according to the new study by Shah, an assistant professor of public policy in the UCLA Luskin School of Public Affairs, and Cunningham. Their paper, “Decriminalizing Indoor Prostitution: Implications for Sexual Violence and Public Health,” was published recently in the Working Paper Series by the National Bureau of Economic Research.
“Everything about this experiment is unusual, so in a way, we didn't know what was more surprising — that a state could ‘accidentally’ legalize indoor prostitution, that no one would practically know about it for 23 years, that we would be successful at obtaining so many different sources of data to investigate it, or that we would find reductions in reported rape offenses and gonorrhea rates,” they said.
