The main purpose of the Permanent Study Group (PSG) is to develop and strengthen the ties between the fields of public administration/public management and political science/public policy by bringing scholars from these fields together. Special attention is given to implementation theory and research. Over the past years, the Study Group has contributed to gathering older and new generations of implementation researchers who contribute and publish on cutting-edge topics of policy implementation. The future agenda of PSG XIII includes making work of systematic comparative research, addressing both the limits and capacities of administration, and developing dialogues between academia and practice.
