Differentiated Integration at the EU Member State Level

This book breaks new ground by providing a large-N approach to describing and explaining the phenomenon of differentiated integration at the level of EU countries. It deduces hypotheses from the major European integration theories – intergovernmentalism, supranationalism, and constructivism – and subjects them to systematic hypothesis testing based on the new EUDIFF datasets and panel data analyses. In addition, it examines the logical relationship between the three theories as well as their relative explanatory power and empirical corroboration. For this purpose, it carries out an empirical comparison of the theories and their respective assumptions, hypotheses, indicators, and empirical models.
