Stephen Kastoryano, PhD Biography

Assistant Professor in Empirical Econometrics at the University of Mannheim (Germany)
Pro to the question "Should Prostitution Be Legal?"

“Our empirical results show that opening a tippelzone [designated legal street prostitution zone in the Netherlands] reduces sexual abuse and rape. These results are mainly driven by a 30-40 percent reduction in the first two years after opening the tippelzone. For tippelzones with a licensing system, we additionally find long-term decreases in sexual assault and a 25 percent decrease in drug-related crime, which persists in the medium to long run. We do not find evidence for effects on other types of crime, such as violent assaults and possession of illegal weapons.”
