Coalition Agreements as Control Devices

Many coalition cabinets negotiate lengthy coalition contracts outlining the agenda for the time in office. Not only does negotiating these agreements take up time and resources, but compromises have to be made, which may result in cabinet conflicts and electoral costs. This book explores why political parties negotiate such agreements, and argues that coalition agreements are important control devices that allow coalition parties to keep their partners in line. The authors show that their use varies with the preference configuration in cabinet and the allocation of ministerial portfolios. First, they posit that parties will only negotiate policy issues in a coalition agreement when they disagree on these issues and when they are important to all partners. Second, since controlling a ministry provides parties with important information and policy-making advantages, parties use agreements to constrain their partners particularly when they control the ministry in charge of a policy area. Finally, they argue that coalition agreements only work as effective control devices if coalition parties settle controversial issues in these contracts. The COALITIONAGREE Dataset is used to evaluate the expectations set out in the book; the dataset maps the content of 229 coalition agreements that were negotiated by 189 parties between 1945 and 2015 in 24 Western and Eastern European countries. The results show that coalition parties systematically use agreements to control their partners when policy issues are divisive and salient and when they are confronted with a hostile minister. These agreements only effectively contain conflicts, however, when parties negotiate a compromise on precisely the issues that divide them.
