This book examines the economic theories and policies that underline the governance of the European Union. Through exploring the history of European economic governance and how this framework has evolved over time, it contextualises theoretical influences, policy debates surrounding the European Union and its instruments of governance, including the European Semester, Six Pack, Two Pack, and Fiscal Compact. Forthcoming reforms to fiscal rules and the economic policy architecture of the European Union are also discussed, with a particular focus on the impact of the COVID-19 pandemic.  This book aims to give readers a broad understanding of the framework and dynamics that define European economic governance. It will be relevant to researchers and policymakers interested in the European political economy.
