Intergovernmental fiscal institutions are the overarching framework for relations across government levels. They comprise the constitutional set up of a country; the division of power between government levels; the prevalence of fiscal rules across government levels; intergovernmental budget frameworks; the role of independent bodies such as fiscal councils in shaping fiscal relations; the inter-ministerial organisation of fiscal decision making; and other framework conditions shaping intergovernmental fiscal relations and fiscal policy. This book brings together academics and practitioners dealing with or being involved in shaping the institutions of intergovernmental fiscal relations. It has an interdisciplinary focus and provides insight from various academic or practitioners’ fields: economists, political scientists, budget management specialists and others.
