The public sector continues to play a strategic role across the world. The last thirty years have seen major shifts in approaches to public sector management in many different countries. There is also a fierce debate across academic disciplines about contemporary public adminstration/management: some advocate the use of more managerialist approaches; while others critique them. New functions have also arisen in the public sector, such as evaluation or management consulting, which require analysis. There is a renewed need for an analysis of contemporary public sector organisations, which are changing rapidly before our eyes. Thus it is time for an authoritative assessment of the major trends in public management, embracing both their intended and unintended effects. This Handbook brings together leading international scholars to comment on key current issues. The individual chapters include a mix of broad overviews, in depth exploration of particular thematic areas and analyses of different theoretical perspectives such as political science, management, sociology and economics. The authors have been given sufficient space to develop their distinctive arguments. The editors provide an overall concluding chapter. The Handbook combines scholarly rigour, engaging writing from senior authors and high policy relevance. It will be relevant to advanced students, researchers and reflective public sector practitioners.
