Incumbency advantage and candidate characteristics in open-list proportional representation systems: Evidence from Indonesia

Abstract

We use evidence from Indonesia's April 2014 legislative elections to study the relationship between incumbency, list position, candidate characteristics, and electoral success in open-list PR systems. Contrary to a recent literature identifying an incumbency disadvantage in other large developing democracies, we identify a consistent personal incumbency advantage in Indonesia. However, we argue that this advantage is mediated by party choices over how incumbents and newcomers are ranked on party lists, a key heuristic for voters in low-information electoral environments such as Indonesia.
