The aim of the paper is to investigate to what extent political parties in the Scandinavian parliaments express opinions on labor immigration in line with the policy preferences predicted by the Stolper-Samuleson theorem. A hypothesis derived from the theorem suggests that left wing parties traditionally connected to labor interests should favor restrictions on labor immigration to a greater extent than right wing parties traditionally connected to businesses and market interests. To establish any such trend, parties are placed on a left-right axis according to their given Rile scores. The findings indicate that there is some evidence for a left-right divide regarding parties' assumed factor interests labor and capital, but the basis for these findings are limited and inferences should be made with care.
