In this final JPP issue from the Centre for the Study of Public Policy, I review its distinctive aim of publishing articles applying relevant concepts from the social sciences to problems facing contemporary governments. The aim is illustrated by reprinting five articles from past issues and a Symposium (1986) discussing different ways in which social science journals are edited. The articles are Bowen (1982); Weaver (1986); Rose (2002); Silvia (2004); Bruner and Abdelal (2005).

Irrespective of the level of government, public officials increasingly face the challenge of evaluating and making choices between more instruments. Agencies are intended to be a new and different type of governance instrument offering prospects for stronger input from experts, greater transparency and depoliticised decisions. Using ‘legitimacy’ as the framework, this study compares an agency (European Aviation Safety Agency) to comitology and its predecessor (a sui generis intergovernmental regulatory network). Although EASA is often heralded as a major change, the conclusions here are that its predecessor was quite effective and that comitology has been greatly improved and could have been explored as alternative instrument. Therefore, the agency solution was neither unavoidable nor necessarily better.

Based on extensive new empirical fieldwork (via a case study of the reform of the territorial State in 2007–2010), this article interrogates the meaning of the prefectoral institution in France. The central puzzle this article addresses is the survival of a pre-democratic institution – the Prefect in – a democratic, decentralizing and Europeanised Republic. Changing conditions have required institutional resilience and adaptation in a period of state restructuring and rescaling. The case study of the prefectures as old institutions is framed using language and tools of new institutionalism across three dimensions: the timing and sequence of decision-making, the logic of appropriateness, and interaction. Beyond the narrow case of the prefectures in France, the article makes the case for combining modes of institutionalist analysis in order to penetrate generalities about the black box of institutions.
