Der einfluss von koalitionsaussagen, programmatischen standpunkten und der bundespolitik auf die regierungsbildung in den deutschen ländern

Party politics at the German state level plays a decisive role for patterns of party competition and for legislative decision-making at the federal level. This article analyses the impact of party politics at the state and the federal level on the formation of coalition governments in the German Laender. The empirical analysis is based on a unique dataset that covers information on the state parties' programmatic positions, their pre-electoral alliances, and the structure of party competition on the federal level in the time period between 1990 and 2007. The results reveal that the programmatic positions of state parties have a decisive impact on government formation. Other relevant factors are the parties' relative strength, their coalition preferences and the partisan composition of government and opposition on the federal level.
