This critical book focuses on two dominant reform agendas - managerialism and politicisation - to examine the condition of Anglophone countries after 40 years of reform to public sector management and governance. Comparing four countries using the Westminster system - Australia, Canada, New Zealand and the United Kingdom - John Halligan explores the changes resulting from distinctive reform agendas, exposing performance shortfalls and unintended consequences, such as bureaucratisation. Offering a broad overview of the implementation and outcomes of key administrative developments, Halligan unpacks those traditions and conventions of governance in Anglophone countries that have been disrupted by unrestrained political executives, producing dramatic imbalances in management and governance systems. Judicious and incisive, this book will be crucial reading to postgraduate and advanced undergraduate students of public policy seeking an in-depth understanding of both historic and contemporary reforms to public management and governance. Halligan's comparative approach to public management systems will also benefit government practitioners and specialists working closely with governments.
