This paper studies the empirical relevance of the close ties between a
central trade union and the social democratic political party using t
ime series data for Norway. Using a structural wage-price model we est
imate that changing from a bourgeois to a social democratic government
reduces manufacturing wages in the long run by 2.3 percent. This resu
lt is consistent with a wage bargaining model augmented by political p
references of the union leaders. Private service wages are not directl
y affected by government type, but wage spillover effects imply that t
he long-run dampening effect in the private service sector is around 2
percent. The results also support the proposition of the Scandinavian
model of inflation that the traded goods sector is the wage leader.
