Voter Turnout in Norway: Time, Space, and Causality

This article focuses on diachronic and synchronic variation in Norwegian electoral turnout from 1945 to 1991. The model contains aggregate data divided into two-year intervals with regions as cross-sections. The impact of both socio-economic and political variables is tested. The two-dimensional view on turnout variation makes it possible to distinguish between short-term and long-term effects, as well as between national versus local factors. In contrast to related studies, this analysis actually tests for causality relationships between different political variables. The empirical results indicate that an increase in either national unemployment or regional income contributes to an increase in turnout rates. Electoral participation is also positively related to Labour support, industrial employment and strike activity.
