This book provides a conceptual and methodological approach for researchers evaluating governance and policy in the face of complexity, and demonstrates the application of this approach across different governance and policy contexts. It fills a significant gap in the literature on governance, and proposes a theoretical focus on coordination to enable the assessment of multi-tier, cross-sector governance institutions and policy. It also introduces a range of applications for the proposed approach, including two case studies of governance and policy for the built environment and health services. The book introduces, analyses and draws from a range of perspectives in political economy, political science, policy analysis and evaluation. It also engages with longstanding debates in political economy about states and markets, which are largely overlooked by political science analyses of coordination challenges in governance. The book will appeal to scholars and students of governance, public policy and political science.
