Challenges to multiparty governments: How governing in coalitions affects coalition parties' responsiveness to voters.

How does governing in coalitions affect coalition parties' responsiveness to voters? In this article, we seek to understand the relationship between political parties' participation in multiparty governments and their responsiveness to voters. We argue that the extent to which coalition parties respond to policy priorities of voters is influenced by the divisiveness of policy issues within the cabinet and the ministerial responsibility for policies. To test our hypotheses, we combine data on the issue attention of 55 coalition parties from the Comparative Manifestos Project with data on government composition and data on the policy priorities of voters from the Comparative Study of Electoral Systems and various election studies in 45 elections across 16 European countries from 1972 to 2011. While we find that intra-cabinet divisiveness decreases coalition parties' responsiveness, we find no effect for portfolio responsibility. Our findings shed light on the relationship between party competition and coalition governments and its implications for political representation. [ABSTRACT FROM AUTHOR]
