Explaining candidate turnover. Evidence from a comparative analysis in 10 European established democracies with a list-PR system

This article investigates determinants of candidate turnover in 10 European established democracies with list-PR electoral systems. We identify party and election variables that affect the supply and demand of new candidates on the parties’ lists. In addition, we apply a weighted candidate turnover measure to investigate the dynamic of renewal on high-ranked list positions. We built an original dataset that contains 3344 electoral lists of represented political parties. Hypotheses are tested by means of a multilevel analysis of political party list renewal rates. At the party level, leadership change and larger party size in terms of members are found to coincide with higher general turnover. At the system level, general turnover is higher in elections with closed lists and high electoral volatility. At higher positions on the list, candidate turnover appears not to be affected by the party- and system-level variables identified in the broader literature.
