Keeping tabs through collaboration? Sharing ministerial responsibility in coalition governments

Abstract

AbstractMoving past the conventional focus on ministerial portfolios, this paper investigates how coalition governments allocate and share ministerial responsibility for individual policy issues. Sharing responsibility induces coalescing parties to collaborate on policy issues, which addresses the problem of ministerial autonomy. Consequently, I argue that incumbent parties in coalition governments share ministerial responsibility for contentious and salient policy issues. This claim is corroborated based on a newly elicited dataset of over 30,000 ministerial policy responsibilities from Denmark, Germany, and the Netherlands. The findings have important implications for scholarship on coalition governments, as they demonstrate that incumbent parties can use the design of ministerial portfolios itself to insulate a coalition compromise from partisan deviations.
