Parties' Influence during Government Policy Negotiations: Parliamentary Dynamics and Spatial Advantages in the First Italian Republic

As long as parties are interested in policies, they will always have incentives for influencing the cabinet bargaining process, although they do not necessarily shape its outcome to the same extent. Being a member of the invested government, for example, should increase the leverage a party enjoys when bargaining over the cabinet programme. Nevertheless, depending on institutional and political conditions, non-cabinet parties may also play a role in affecting cabinet policy positions. Despite being widely recognised in the theoretical literature, this point has received considerably less attention in empirical studies. By focusing on cabinet bargaining outcomes during the First Italian Republic, the article shows that spatial advantages associated with parliamentary dynamics, including those possessed by non-cabinet parties, can be no less significant in capturing policy payoffs than government membership, even after controlling for other relevant institutional and behavioural factors.
