This book examines the links between major contemporary public sector reforms and neoliberal thinking. The key contribution of the book is to enhance our understanding of contemporary neoliberalism as it plays out in the public administration and to provide a critical analysis of generally overlooked aspects of administrative power. The book examines the quest for accountability, credibility and evidence in the public sector. It asks whether this quest may be understood in terms of neoliberal thinking and, if so, how? The book makes the argument that while current administrative reforms are informed by several distinct political rationalities, they evolve above all around a particular form of neoliberalism: constructivist neoliberalism. The book analyses the dangers of the kinds of administrative power seeking to invoke the self-steering capacities of society and administration itself.
