Exploring the connection between electoral systems and personalized behaviour among politicians and voters

Abstract

The personalization of politics includes electoral reforms that give voters more opportunity to select individual representatives as well as behavioural personalization among voters and politicians. Institutional research suggests that the latter is a function of the former, but it remains unclear whether the association between the two types of personalization is actually causal. In order to get empirical leverage on this question, we analyze local elections in Denmark, which feature within-district and within-party variation in the openness of party lists. Using detailed information on the behaviour of politicians and voters, we find that, once we take differences between districts and parties into account, the personalization of electoral rules has a negligible effect on behavioural personalization.
