This book introduces and applies the economic way of thinking to public policy and public administration. It provides a non-technical introduction and assumes no prior economic or mathematical training but looks closely at the methodological and normative assumptions underlying economic analysis. It provides a deep understanding of the method than a simple technical presentation would allow. After introducing the basic assumptions of the economic method, the book considers the analysis of market failure, the role of government in a market economy, behavioural economics, bargaining in government, bureaucracy, interest groups, and levels of government. By providing a balanced introduction to and overview of economic approaches to government, the book will be useful to undergraduate and postgraduate students in public administration and public policy, as well as academics and practitioners in these fields interested in the application of the economic way of thinking.
