“Party Instability in Parliaments”

SPEAKER: Sona Golder (Pennsylvania State University)

ABSTRACT:

In many contemporary democracies it is common for the members of parliament (MPs) to leave their parliamentary parties to defect to other parties, to create new parties, or to become parliamentary independents. In the Instaparty project (funded by the Norwegian Research Council), we examine party instability in parliaments in eight European democracies. The project has three objectives: to map out diverse forms of instability, to explain why instability occurs, and to understand whether and how instability affects voter support of parties. This presentation focuses mainly on work related to the second objective, briefly discussing the party (re)affiliation strategies of the (surprisingly common) independent MPs before addressing the effect that party support in public opinion polls has on switching. We find that changes in party support in polls affect parliamentary party switching through two channels. First, MPs with a low probability of re-election are more likely to leave their current party group. Second, legislators also switch out of parliamentary parties that are unlikely to enter government after the next election, particularly in the period preceding the next election.
