The Privatisation and PPPs (P4) Research Group was established in 2003 as a multi-disciplinary research group at the University of Limerick. The group is composed of academic experts in disciplines such as economics, finance, public management, and industrial relations. Those scholars are actively engaged in research into various dynamic policy issues across infrastructure sectors, including privatisation, deregulation, market liberalisation, and public-private partnerships (PPPs). Policy issues include the economic and social effects of such policies (including impacts on workers, consumers, investors, and communities); their corporate governance aspects; management of the alternative processes, legal dimensions and governance aspects (including the accountability of decision-makers to citizens and organisations in different national and international settings).

The stated mission of P4 is:

To collaborate with partners from the public, private and non-profit sectors for the purpose of developing research and disseminating knowledge around change in the infrastructure sectors that are core to sustainable economic development and the well-being of society.
