The Swedish Sex Purchase Act: Claimed Success and Documented Effects
http://chezstella.org/docs/etude-suede-2011.pdf
The laws on prostitution in Sweden make it illegal to buy sexual services, but not to sell them. Pimping, procuring and operating a brothel are also illegal. The criminalisation of the purchase, but not selling, of sex was unique when first enacted in 1999, but since then Norway and Iceland have adopted similar legislation, both in 2009, and France began enacting a similar law in 2013.
