Abstract
Abstract. Measuring of party system stability in Eastern Europe during the first decade of democratic elections presents problems. The traditional quantitative measure – volatility – does not distinguish between the dynamics among incumbent parties and the rise of genuinely new ones. I propose a new additional measure – success of genuinely new parties – and compare it to volatility. The subsequent performance of initially successful genuinely new parties is analysed. While volatility has been remarkably high in East European countries, the genuinely new parties have, in general, not been very successful. Instability of party systems in the region stems rather from the inner dynamics of incumbent actors than from the rise of new contenders.
