One famous definition says public policy includes whatever governments decide not to do
In 1972 Thomas Dye defined public policy as anything governments choose to do or not to do. Critics call the formula empty; Dye cheerfully admitted it was meant to cut short elaborate academic arguments about definitions. Its lasting point is that inaction is also a decision, with consequences just as real.
Other scholars disagree about whether policy is mainly an idea or mainly what happens on the ground. Richard Titmuss, writing from a social contract perspective, treated it as the principles governing action toward chosen ends. In the 1950s David Easton argued for a broader view with an American example: if a school system formally banned racial discrimination while local boards drew attendance zones that kept Black pupils segregated, both the impartial rule and the discriminatory practice were part of the policy. He called policy a web of decisions and actions that allocates values.
Later definitions have gone both ways. Paul Cairney counts everything from signals of intent to final outcomes, B. Guy Peters speaks of activities governments use to change their economy and society, and Antonio Lassance in 2020 framed it as an institutional plan for tackling a core problem, steered by an underlying theory of change that he believes can be tested. Analysts also separate outputs, the actions actually taken, from outcomes, the effects on society.
To make sense of the process, Harold Lasswell introduced the policy cycle in a 1956 book, The Decision Process. Its stages usually run from agenda setting through formulation, legitimation and implementation to evaluation. Newer frameworks challenge that tidy sequence. John Kingdon describes policy windows that open when separate streams of problems, proposals and politics converge, with timing and entrepreneurs crucial. Frank Baumgartner and Bryan Jones explain long stretches of stability broken by sudden lurches, and Paul Sabatier traces how coalitions sharing beliefs shape contested fields over many years.
Suzanne Mettler and Mallory SoRelle add policy feedback: existing programmes reshape the politics that produce future ones. Implementing all this is the job of public administration, and the resulting policies reach into schooling, health care, employment, finance, transport and much else, whether made by elected officials alone or together with experts, communities and other non-state actors.
