Summary

Paul Sabatier and Hank Jenkins-Smith introduced the Advocacy Coalition Framework (ACF) in the late 1980s to refine the theoretical and methodological tools available for the study of the policy process. Since the late 1990s, the use of the framework has grown in use outside the United States and it is now applied to study a broad range of policy arenas in all continents. ACF scholars have created a core community that regularly synthetizes findings from applications of the framework, giving the ACF the form of a true research program.

The ACF has three principal theoretical domains: advocacy coalitions, policy subsystems, and policy change. The ACF posits that advocacy coalitions and policy subsystems are the most efficient ways to organize actors interested in the policy process for empirical research. The policy subsystem is the main unit of analysis in the ACF, and there are four paths leading to policy change. Expectations about the interactions between and within the three theoretical domains are contained in 15 main hypotheses which have received different degrees of confirmation since the late 1980s. The aspect that has received more attention in existing applications is the effect that external events have on policy change.

The development of the ACF is supported by an active community of scholars that constantly reviews venerable as well as emerging criticisms, introducing adjustments that expand the heuristic power of the ACF in a controlled way. However, some areas in need of further refinement relate to: policy-oriented learning, interactions across subsystems, the theoretical foundations to identification of belief systems, and how the interactions between beliefs and interests affect coalition behavior.
