“…Because the structure and length of a journal article limits us in the extent to which we can explore the validity of knowledge creation in policy analysis, we focus on just three theoretical approaches that deal with policy change: punctuated equilibrium theory (PET) (Baumgartner & Jones, , ), incremental change (Mahoney & Thelen, ; Streeck & Thelen, ), and institutional isomorphism (DiMaggio & Powell, ). We go beyond previous systematic literature reviews on PET (Kuhlmann & van der Heijden, ) and incremental change (Van der Heijden & Kuhlmann, ) by asking questions that go beyond single approaches and focus on concepts of policy change in policy analysis more broadly. As will become clear in the article, we found, on the one hand, sufficient overlap in the application of these three theories to suggest patterns of usage across them, and, on the other hand, differences in the application of the three theoretical approaches.…”
