Reassessing the concept of policy paradigm: aligning ontology and methodology in policy studies.

The concept of policy paradigm, which was developed by Peter Hall in 1993, has given rise to an abundance of literature on ideas and policy dynamics. Despite its theoretical value, however, the original concept was insufficiently specified and has been used in problematic ways by many policy scholars, thereby undermining the validity of their descriptive and causal inferences. The main argument defended in this article is that scholars studying policy paradigms should devote as much attention to the ideas of policy makers as to the policies they adopt, while distinguishing between the two constructs as much as possible. This article reviews these issues and puts forward seven guidelines that aim to better circumscribe the concept of policy paradigm and improve research on ideas and policy dynamics.
