Challenges to liberal intergovernmentalism

Slapin (2011) and Finke et al. (2012) represent the best theory-based book-length studies of the most active period of treaty reform in the history of the European Union – from the Treaty of Amsterdam to the Treaty of Lisbon. These works offer the opportunity to assess the extent to which liberal intergovernmentalism – a ‘baseline’ theory of regional integration – has withstood empirical scrutiny. I first address what I consider a misinterpretation of liberal intergovernmentalism – the presumed pre-eminence given to a country’s relative capability. I then identify challenges to this framework. Methodologically, they concern the measurement of preferences, value of disagreement and opportunities for linkages in treaty negotiations. I then assess evidence of lower-than-unanimity thresholds for treaty reform, which may represent a theoretical challenge. Finally, I suggest that focal points and bargaining dynamics deserve greater scholarly attention.
