The Nordic model is a form of social democracy which is a form of socialism; if the first is applicable, the second is as well, and if the second is applicable, the third is as well.
Right. I didn't mean "Socialism" in a strict/formal sense. I always thought of Nordic countries as "kind of socialism". Apparently, there exist more correct and exact terms, as you pointed out.
"Socialism" (http://en.wikipedia.org/wiki/Socialism) isn't really applicable.
