Effectiveness of the European Semester: Explaining Domestic Consent and Contestation

Which factors explain domestic consent or contestation of European Union (EU) policy guidance issued within the framework of the European Semester (ES)? To address this question, this article analyses national parliamentary party positions on EU policy guidance in two cycles of the ES (2014 and 2015) in Austria, France, Germany and Ireland. Whereas parliamentary parties in Austria and Ireland expressed their consent to EU policy guidance, parliamentary parties in Germany and France were polarised. The empirical analysis presented in this article establishes that strong formal powers in budgetary matters are a prerequisite for parties to contest EU policy guidance. However, parliamentary party positions depend most on whether the content of EU policy guidance reflects a party's economic interests
