Coalition Policy-Making under Constraints: Examining the Role of Preferences and Institutions.

While much has been written about the formation and termination of coalitions, comparatively little attention has been paid to the policy output of multiparty governments. The present study attempts to narrow this research gap by analysing policy-making in three Austrian coalition governments between 1999 and 2008. Drawing on the party mandate literature, a manually coded textual analysis of election manifestos is conducted that yields a dataset containing over 1,100 pledges. The fulfilment of these pledges is taken as the dependent variable in a multivariate analysis. The results indicate that institutional determinants (adoption in the coalition agreement, ministerial control, and policy status quo) significantly influence the chances of pledge fulfilment and thus present a powerful predictor of coalition policy output. By contrast, factors related to parties’ preferences (consensus between parties, policy distance, pledge saliency, and majority support in parliament) do not have an impact.
