The impact of coalition parties on policy output – evidence from Germany

This paper examines two crucial questions related to coalition politics and representative democracies. How do parties’ ideological positions translate into cabinet policy positions? And how does the relative impact of parties vary over the legislative term. Using an original dataset of 74 social and budgetary laws from nine German coalition governments, the paper shows that, on average, government parties influence cabinet policy position according to their relative strength. However, the relative impact of coalition parties varies significantly during the term. At the beginning of the term in office, the policy positions of the cabinet are representative of the overall cabinet ideology, but the policy positions strongly move towards the position of the party representing the median when the next election approaches.
