The degree and manner of party system institutionalization and party regulation is presuppossed to have a major impact on both democratization as the way party democracy is functioning. The study uses a time-series method of analysis to identify changes in party system regulation and links these changes to the stability of a party system such as electoral volatility and party strength. By doing so, this thesis delivers a valuable insight in the pivotal role party system institutionalization plays in democratization and the stabilization of young party systems.Show less
