The role of agencies in policy-making

There is an extensive literature on the proliferation of agencies and the delegation of authority to such bodies across different countries. Much of this research asks whether New Public Management (NPM)-style agencification reforms have been implemented according to the original objectives, and what consequences - intended or unintended - the reforms have produced. Yet much of this research lacks an explicit link to the literature on the policymaking functions of public bureaucracies and their interactions with elected politicians. What are the consequences of agencification for the policy process at large? What policy relevant tasks do agencies perform, to what extent are they involved in policy-making, and what factors influence the quality and quantity of their participation? This introductory article gives an overview of key concepts such as " public agencies" and " policy autonomy" and the research literature. Moreover, it critically discusses relevant theoretical perspectives, outlines the articles included in this themed issue and argues for a more systematic and theoretically guided analysis of agencies' role in policy-making. © 2012 Policy and Society Associates (APSS).
