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.	The Multiple Streams Framework (MSF) is a theory of agenda setting and policy change developed by John Kingdon in his 1984 book Agendas, Alternatives, and Public Policies. It explains why some issues rise to prominence and some solutions are adopted while others languish, by modelling the policy process as three largely independent 'streams' — problems, policies, and politics — that flow through the system. Change becomes possible when these streams are joined together at a fleeting 'policy window', often through the efforts of a 'policy entrepreneur'. The framework emphasises ambiguity, timing and chance over orderly, rational problem-solving.
