TY - JOUR A1 - Stecker, Christian T1 - Determinants of party unity a comparative analysis of the german state parliaments JF - Politische Vierteljahresschrift : Zeitschrift der Deutschen Vereinigung für Politische Wissenschaft N2 - Using 2184 roll call votes (RCV) from 42 electoral terms this paper tests the influence of different factors on party unity in the German Landtage. It finds evidence that the strategic calculus behind RCV-requests is a crucial predictor for unity scores. The requesting party group is on average significantly more united than its parliamentary competitors. It also shows that government status, thin governmental majorities and a growing ideological distance between government and opposition increase unity. Electoral incentives, however, do not seem to influence voting behavior in the German Lander.
