Resumo	Punctuated Equilibrium Theory (PET), developed by Frank Baumgartner and Bryan Jones in their 1993 book Agendas and Instability in American Politics, explains how policymaking is characterised by long periods of stability and incremental change interrupted by brief, dramatic bursts of major change. Borrowing the metaphor from evolutionary biology, it argues that the way an issue is understood (its 'policy image') and the institutional 'venue' in which it is handled normally reinforce a stable equilibrium — until attention shifts, the image is reframed, and rapid, large-scale change punctuates the calm.	Policy feedback analysis examines how policies, once enacted, reshape the politics that follow — turning yesterday's policy effects into today's political causes. Drawing on Paul Pierson's foundational 1993 article 'When Effect Becomes Cause,' it holds that policies are not just outputs of politics but powerful forces that create resources and incentives for groups, build administrative capacities, and shape how citizens understand their interests and their government. By tracing these resource and interpretive feedback effects over time, the method explains why some policies become self-reinforcing and politically durable, why others undermine their own support, and why policy change is often path-dependent and hard to reverse.
