VAAs as sources of volatility and fragmentation: self-selection effects and genuine effects

ABSTRACT

Recent studies show that using Voting Advice Applications (VAAs) affects party preferences of voters, and hence leads to party switching. Party switching is a necessary but insufficient condition for volatility (a net switch of voters to other parties) and fragmentation (more parties gaining seats) at the aggregate level of electoral constituencies. The research question addressed here is whether the availability of VAAs in electoral constituencies weakens or strengthens trends towards greater volatility and fragmentation as observed in western democracies in the last decades. The data come from 380 Dutch municipalities during the 2014 Dutch municipal council elections. In 133 of them a VAA was available. Using a moderated mediation model that controls for the municipal self-selection of a VAA, we find that a VAA by itself leads to higher levels of volatility and fragmentation. However, VAA availability has a dampening effect in municipal constituencies with characteristics (e.g. population size, ethnic diversity, young average age) that would otherwise make them more susceptible and prone to volatility and fragmentation.     

Issue news and electoral volatility

Abstract. This article shows that issue coverage in the media partly explains both the political landslide at the 1994 elections in the Netherlands and the political continuity in the 1994 elections in Germany. Theories of issue voting guided the research. Issue ownership theory maintains that voters will remember which party has the best record of solving problems in emphasized issue areas. Proximity models and directional models suggest that voters' own issue positions will be compared to the perceived issue positions of parties. A longitudinal content analysis of ten newspapers and five television news programmes was performed to ascertain selective issue emphasis and the issue positions attributed to parties. Election outcomes and weekly opinion polls were used to measure the volatility of the vote.
