Here is the ACF story.
People engage in politics to turn their beliefs into policy. They form advocacy coalitions with people who share their beliefs, and compete with other coalitions. The action takes place within a subsystem devoted to a policy issue, and a wider policymaking process that provides constraints and opportunities to coalitions.
The policy process contains multiple actors and levels of government. It displays a mixture of intensely politicized disputes and routine activity. There is much uncertainty about the nature and severity of policy problems. The full effects of policy may be unclear for over a decade. The ACF sums it up in the following diagram:
Policy actors use their beliefs to understand, and seek influence in, this world. Beliefs about how to interpret the cause of and solution to policy problems, and the role of government in solving them, act as a glue to bind actors together within coalitions.
The outcome is often long-term policymaking stability and policy continuity because the ‘core’ beliefs of coalitions are unlikely to shift and one coalition may dominate the subsystem for long periods.
There are two main sources of change.
- Coalitions engage in policy learning to remain competitive and adapt to new information about policy. This process often produces minor change because coalitions learn on their own terms. They learn how to retain their coalition’s strategic advantage and use the information they deem most relevant.
- ‘Shocks’ affect the positions of coalitions within subsystems. Shocks are the combination of events and coalition responses. External shocks are prompted by events including the election of a new government with different ideas, or the effect of socioeconomic change. Internal shocks are prompted by policy failure. Both may prompt major change as members of one coalition question their beliefs in the light of new evidence. Or, another coalition may adapt more readily to its new policy environment and exploit events to gain competitive advantage.
The ACF began as the study of US policymaking, focusing largely on environmental issues. It has changed markedly to reflect the widening of ACF scholarship to new policy areas, political systems, and methods.
For example, the flow diagram’s reference to the political system’s long term coalition opportunity structures is largely the response to insights from comparative international studies:
- A focus on the ‘degree of consensus needed for major policy change’ reflects applications in Europe that highlighted the important of proportional electoral systems
- A focus on the ‘openness of the political system’ partly reflects applications to countries without free and fair elections, and/ or systems that do not allow people to come together easily as coalitions to promote policy change.
As such, like all theories in this series, the ACF discusses elements that it would treat as (a) universally applicable, such as the use of beliefs to address bounded rationality, and (b) context-specific, such as the motive and opportunity of specific people to organize collectively to translate their beliefs into policy.
