Scholars have developed a wide range of theories to explain both stability and change in policy subsystems. In recent years, a burgeoning literature has emerged that focuses on the application of network analysis in policy research, more formally known as Policy Network Analysis (PNA). This approach, while still developing, has great potential as an integrated theoretical framework that brings together multiple theories under a single conceptual paradigm. In this paper, the authors demonstrate how the insights of three other established policy theories--namely, the Advocacy Coalition Framework (ACF), Punctuated-Equilibrium theory (PET), and the Policy Entrepreneur Model (PEM)--may be augmented under a synthesis theory of policy networks to provide a more conceptually coherent theory of policymaking that may be useful for explaining periods of both stability and change.
