Who Gets Their Way in Coalition Policy?

Alessio Albarello (University of Rochester)

Abstract: In coalition governments, parties need to agree on a common position. Whose preferences pre- vail? I test alternative theories for the determination of the policy compromise in multiparty governments. I reject a prominent theory that coalition partners’ influence on policy is propor- tional to their share of seats. On the other hand, I cannot reject the hypothesis that coalition partners exert equal influence on policy compromises, independent of seats. More extensive analysis using additional explanatory variables provides moderate evidence for increased party influence on policies when the party is the Formateur or closer to the parliamentary median, ceteris paribus.
