In the late 1980s, yet another generation of public administration theorists began to displace the last.
The new theory, which came to be called New Public Management, was proposed by David Osborne and Ted Gaebler in their book Reinventing Government.
The new model advocated the use of private sector-style models to improve the efficiency and service-orientation of the public sector.
During the Clinton Administration (1993–2001), Vice President Al Gore adopted and reformed federal agencies using NPM approaches.
In the 1990s, new public management became prevalent throughout the bureaucracies of the US, the UK and worldwide.
