Reforming the Common Agricultural Policy provides a comparison of the reforms of the European common agricultural policy. It analyses the determining factors by applying a multi-level (international, European and national), a multi-issue (agricultural and non-agricultural), and a policy network approach (the evolution of the corporatist model). It is demonstrated that the international trade level played a determining role. It discusses whether cumulative changes brought about a paradigm change and argues that policy feedbacks of each reform generated change, up to a change in policy paradigm.
