This book investigates the constitutional and partisan powers of presidents in Asia and how these powers are utilized in policymaking. It offers a comprehensive analysis of presidential and semi-presidential democracies across the continent, establishing a baseline measure for presidential 'strength' based on both constitutional and partisan authorities. Through comparative case studies of Afghanistan, Indonesia, the Philippines, South Korea, Sri Lanka, and Taiwan, the book examines the practical application of these powers within actual policy-making processes.

This book is recognized as a significant contribution to the study of Asian political systems, particularly focusing on the executive branch. Scholars likely find its comparative framework and detailed case studies valuable for understanding the nuances of presidential power in diverse Asian contexts. The analysis of how constitutional and partisan strengths translate into actual policy outcomes provides a robust foundation for further research in comparative politics and Asian governance.
