Effects of campaign spending in an open list PR-system : the 2003 legislative elections in Flanders/Belgium

In countries with a majoritarian electoral system, the expenses of challengers are generally found to have a stronger effect on the electoral outcome than the expenses of incumbents. Research on campaign expenditure effects in Brazil suggests that this is not the case in countries with an open list PR system and large districts. This hypothesis is confirmed by an analysis of the effect of individual campaign expenses on the number of preferential votes in the 2003 legislative elections in Flanders/Belgium. An analysis of high quality candidates shows that the expenses have a substantial effect on the vote which does not vary according to incumbency status. However, the effect of media exposure on the vote is stronger than and largely independent of the effect of campaign expenses. © 2006 Taylor & Francis.
